.

My choice for Android:

• enable-new-contacts-picker

• enable-new-photo-picker

• disable-pull-to-refresh-effect (disable vertical overscrolling for refresh - I always hated that!)

• enable-chrome-duet - love that new design

• enable-scroll-anchor-serialization (not sure if it's working on mobile, but on desktop a nice feature)

• autoplay-policy (document user activation as requirement for autoplay - but for some reason, it is not always working, I wish that autoplay can be disabled entirely)

• download-home-v2 (more UI customization)

• stop-in-background (prevents scheduled tasks in background, thus reduces battery usage)

• enable-horizontal-tab-switcher (UI customization, I prefer this horizontal tab switching)

• upcoming-ui-features (general opt-in for UI flags)

• android-site-settings-ui-refresh (more UI customization)

I am pretty proficient with flags but some of them are not straight forward. When I google for a flags list, it comes up with chromium flags list and other sites, but the explanations are the same as in the actual flags list. There must be a detailed list with explanation; it would be crazy to not exist. Thanks for any help.

In case you didn't know, these are 2 nice flags.

Before, i always noticed that my bluetooth headphones sounded way worse while connected to my chromebook versus on my phone, well, for some reason disabling the "Bluetooth Floss Telephony" flag fix that.

And if you like the idea of your windows matching the current "Material You" design philosophy, you can round your boxy windows, using the "Use rounded windows" flag.

I own the Xperia 1 VI and since the latest firmware came out, lagging has been improved. But I still noticed junky, laggy scrolling when browsing in Chrome for Android.

So I've checked the chrome//flags and found some that really improved this.

Courtesy of AndroidAuthority.

Open Chrome. Click on the address and delete any URL that might be in it. Type the following in the address bar: “chrome://flags/” (without quotation marks). Press Enter.

Search for these three flags and enable them, after enabling them, realunch Chrome:

Smooth Scrolling - Ever notice your scrolling stutter or that it can get a bit sluggish? There could be many reasons it’s happening, but this Chrome Flag will likely improve the situation. Search for “Smooth Scrolling” in the search bar and enable the feature. It’s a great feature Android users should enable, but you can also use it on Windows, Linux, and Chrome OS.

GPU Rasterization - Is Chrome simply not fast enough for you? We know how you can harness the full power of your computer to speed things up. There’s a trick, though; you need to have a dedicated GPU for this one to make any improvements to Chrome’s performance. GPU Rasterization allows Chrome to take some of the workload off the CPU and have your GPU take care of it.

Override software rendering list - GPU acceleration on Chrome is usually only available for supported devices. But, of course, there is a Chrome Flag for nearly everything. You can force Chrome to use GPU acceleration, even on unsupported devices. Just be warned that this may cause compatibility issues, as systems are often not supported for a reason.

Does anyone know if there's a way to bring back the share icon by the address bar using a flag? I use share all the time and it's that extra few touches that irritate the life out of me. I have done some searching but nothing specific comes up. Thanks to anyone who can help.

Do you have any flags enabled/disabled? If so, which one's and why.

Thanks.

So on the list in chrome://flags there used to be a flag called "#organic-repeatable-queries" that got rid of the recent searches on the Chrome Android app homepage. As of today [I think the app probably updated] the flag has disappeared from the list and I see no similar flags. Does anyone know a solution to this?

I'd really appreciate any tips!

This is like the 4th time this has happened on my Android phone. Chrome suddenly changes to tab grid and I have to go to flags and disable a bunch of them in order for it to work. But this time nothing happened. I tried enabling and disabling every flag in every tutorial, and it didn't work. I tried clearing the cache and forcing stop on the app and that didn't work. I tried restarting my phone and still nothing. All tutorials I can find to fix it are outdated from a few weeks ago. Has anyone figured out the fix this time?

Edit: I uninstalled all Chrome updates so it went back to the factory version, then updated it via "my apps and games" section on the Play Store and it worked. But then I tried disabling the flags again, and it went back to tab grid. So I repeated the process and the tabs were stacked like I wanted them to. I don't know how long this fix will work.

Edit 2: I was using Chrome for a few hours and the tabs were stacked. Then I closed it and reopened it and grid is back.

Is their any way to temporarily disable flags. (Similar To What Happnes When Flags Causes Device Crashing)

This is part 2 of the big update post I made about Chrome OS 83. If you missed it, click here to go back.

There are several new experimental features and tweaks in Chrome OS 83 that are unfortunately not part of the default Chrome OS experience. There could be several reasons why: the developers ran out of time for this release cycle, the experiment is deemed too unstable to be left on by default for the stable channel where the majority of the user-base are, or they need to collect more user feedback before shipping them. Some of these experimental features are tucked behind a page where they can be manually switched on or off. These features are called chrome flags. You can find the switches to try these experimental features by typing chrome://flags in Chrome’s URL bar and hitting enter.

Disclaimer: The following is a list of fun, EXPERIMENTAL flags I recommend to test out for those of us itching to experience and test upcoming features from Google. Although I consider these flags to be stable, that might NOT be the case for you! Be prepared to hit the "Reset all to default" button before asking for help, when something odd happens. I am NOT responsible for lost data, unstable sessions, or missing out on important notifications. I recommend making frequent backups of your session, such as backing up your Crostini containers, your important files and app data. Make sure all user profiles are ready for recovery. Enable these flags with caution!!!

Get the Chrome 83 features into Chrome OS 83

Some of you guys were probably expecting the extra privacy and security controls, tab groups, third-party cookie blocking in Incognito mode, etc. in this build of Chrome OS. Almost all of the features did not roll out for most devices. Although Google has officially announced that these features are rolling out in the coming months, you can get these features back by enabling these flags:

• chrome://flags/#tab-groups - This allows you to separate tabs into different groups. This is a huge productivity booster for college students like myself who prefer to separate tabs by subject. See screen recording by Google.

• chrome://flags/#privacy-settings-redesign - enabling the flag brings the completely revamped Privacy and Security settings into Chrome. It includes new artwork, more privacy controls, and a built-in safety that checks for malicious extensions, compromised passwords, and more. This also brings the New Enhanced Safe Browsing security feature. This feature scans your downloads and sends website information to Google Safe browsing to help protect you from malicious websites and files. It’s like a virus scanner, but built into Chrome! See screen recordings by Google for the new privacy and security settings in Chrome and the new Safety Check.

• chrome://flags/#improved-cookie-controls - this flag will bring a switch to the incognito mode new tab page to block third-party cookies in the Incognito session. You can also allow third-party cookies for specific sites by clicking the “eye” icon in the address bar. See screen recording by Google.

• chrome://flags/#shelf-hide-buttons-in-tablet - this flag brings back the fully gestural tablet mode interface that hides the Home, back arrow, and Overview Mode buttons. To activate Overview mode, swipe up from the gesture bar. In the app drawer, pull up from the Shelf hotseat.

• chrome://flags/#extensions-toolbar-menu - this flag brings the new Extension menu that condenses all of your extensions into one extension icon to keep the Chrome toolbar organized. You still have an option to put your extensions next to the omnibox by clicking the “pin” icon. See screen recording by Google.

• chrome://flags/#webui-tab-strip - this flag brings the brand new touch-friendly design to Chrome while Chromebook is in tablet mode. This design also saves space when browsing the web. You can swipe down from the omnibox to reveal tabs. Be careful with enabling tab strip and tab groups - they dont play nice with each other. When the tab strip is active, the tab groups are not, and changes in tab order in the touch mode will mess up your set tab groups when going back. Thanks for the heads-up u/BaronKrause ! See screen recording by Google.

• chrome://flags/#dns-over-https - This adds an additional layer of protection on the web while also providing the user flexibility over the DNS they’re using. Personally, the DNS that my ISP offers is pretty slow, so using Google or CloudFlare’s DNS makes a positive difference in my web browsing experience. YMMV as I couldn't enable this feature with the flag.

Productivity boosters

Work smarter, not harder. The following list of flags will help boost your Chrome OS workflow and make the user experience a whole lot more efficient.

• chrome://flags/#drag-to-snap-in-clamshell-mode and chrome://flags/#multi-display-overview-and-split-view - these flags help improve the laptop overview mode experience by allowing you to drag windows to the side to snap them. Additionally, with multiple virtual desks, you can drag a window from one overview grid and drop it into another overview grid. Small changes, massive productivity booster. Both of these flags must be enabled to prevent a crash. See screenshot

• chrome://flags/#system-tray-mic-gain - is your Chromebook’s microphone too sensitive? With this flag, you can adjust the microphone level of your Chromebook. It will appear in the volume controls in the system tray. See screenshot.

• chrome://flags/#enable-desktop-pwas-tab-strip - this adds a tab strip on top of the PWA and Chrome shortcut window. This is incredibly useful for multitasking with one window (i.e. Google Docs). See screenshot.

• chrome://flags/#ash-limit-alt-tab-to-active-desk - this limits the windows listed in Alt + Tab to the ones in the current active virtual desk. Previously, Alt +Tab would cycle through all windows regardless of the virtual desk, which was quite annoying.

• chrome://flags/#global-media -controls-picture-in-picture - this flag enables Picture-in-Picture controls in the Global Media Controls. Incredibly useful for working with multiple documents and playing media.

• chrome://flags/#enable-assistant-routines - this flag brings the Google Assistant routines feature to Chrome OS. Nice feature carried over from Google Assistant on Android.

• chrome://flags/#tab-hover-card-images - this shows a preview of the tab when you hover your cursor over it. I personally like it, but it may not be to everyone’s tastes. See screenshot.

• chrome://flags/#enable-quick-answers and chrome://flags/#enable-quick-answers-rich-ui - this brings the Google Assistant to the context menu when right clicking a selected word on a page. It's pretty limited right now as it can only find definitions, but there is a ton of potential with this feature in the future. See screenshot.

• chrome://flags/#pdf-two-up-view - this will enable a new option in Chrome's built-in PDF viewer to display two pages side by side. If you want better performance, I recommend leaving this flag alone and using this PDF viewer instead. Make sure you enable “Allow access to File URLs” for this extension to work.

• chrome://flags/#enable-cros-virtual-keyboard-floating-resizeable - enabling this feature flag will allow you to resize the floating virtual keyboard. This is useful for some screens where the floating virtual keyboard is tiny.

• chrome://flags/#new-shortcut-mapping - this feature flag allows you to reassign the shortcut mapping for Caps Lock and the External Meta key to something else (example: change Caps lock key to open Google Assistant).

• chrome://flags/#avatar-toolbar-button - this is useful for quickly managing your Google account, such as password management, modifying payment methods, and saving location addresses for autofill. This puts your Google account profile picture on Chrome’s toolbar. See screenshot.

• chrome://flags/#rar2fs - this flag allows the native Chrome OS file manager to mount RAR archives without plugins. If you need to open several different types of archives, I recommend leaving this flag alone and use this chrome app instead. Note that the Chrome apps are retiring soon in favor of PWAs.

• chrome://flags/#allow-scroll-settings - this feature flag allows you to adjust the scrolling speed for mice and touchpads. This is great for some mice where scrolling the mouse wheel overshoots the amount of scroll intended. Found in Chrome OS settings.

Performance and Battery optimizations

Trying to work with a slow machine can be seriously frustrating, especially when the battery doesn’t last very long. One of Chrome OS’ strengths is its lightweight nature - it's a lot more efficient than a heavier operating system like Windows. There are a few flags you can adjust to help optimize your Chromebook even further. Note that the following flags in this group are likely to cause a crash if they don't play nice on your device.

• chrome://flags/#turn-off-streaming-media-caching - this feature flag prevents caching certain media content to disk for the purpose of improving device battery life for users. Previously, media content was cached to disk during acquisition and playback. Keeping the disk active during this process increases power consumption in general, and can also prevent certain lower-power modes from being engaged in the operating system. Since media consumption is a high-usage scenario, this extra power usage has a negative impact on battery life.

• chrome://flags/#smart-dim-model-v3 and chrome://flags/#smart-dim-new-ml-agent - Chrome OS will use machine learning models to predict whether the user is likely to remain inactive. Chrome OS may dim the screen early or defer dim accordingly based on ML results. This saves battery since the screen won't be left at a high brightness for a prolonged period.

• chrome://flags/#scheduler-configuration - by default, Chrome OS does not use hyper-threading on Intel CPUs in effort to mitigate MDS attacks. Users concerned about the performance loss, such as those running CPU intensive workloads, can re-enable hyper-threading with this flag. Enable with caution!

• chrome://flags/#enable-background-blur - struggling to get good performance on your Chromebook? Blur UI is expensive with CPU usage, so disabling this flag will improve UI performance. Caution: this may cause some graphical bugs!

• chrome://flags/#enable-fling-animation, chrome://flags/#percent-based-scrolling, and chrome://flags/#impulse-scroll-animations - thanks to the Microsoft Edge developers, these flags improve the scrolling performance and experience. This applies to swiping on the touchscreen. The percent-based scrolling flag changes the behavior of mousewheel and keyboard scrolls. Previously, one “tick” of the scroll wheel or arrow key press will scroll by a fixed value in logical pixels. It caused a problem with smaller scrollers since each scroll tick would scroll by a large fraction. To fix this annoyance, the flag translates each “tick” into a percentage.

• chrome://flags/#dynamic-tcmalloc-tuning - This allows tcmalloc to dynamically adjust its thread cache sizes in response to memory pressure. Experimentally, this improved the number of loadable tabs on low end Chromebooks by 10% while also reducing tab switch times by nearly 5%.

• chrome://flags/#use-preferred-interval-for-video - when enabled, the composition rate will adjust based on the video’s actual FPS. This is useful for improving WebRTC performance while saving battery; previously, the display compositor would be updating more frequently than the video stream itself.

• chrome://flags/#enable-vaapi-jpeg-image-decode-acceleration and chrome://flags/#enable-vaapi-webp-image-decode-acceleration - currently, Chrome OS uses libjpeg-turbo and libwebp to decode JPEG and WebP images on the CPU. These flags enable hardware acceleration to JPEG and WebP decoding through Intel’s Video Acceleration API (VA-API), which saves CPU cycles. These flags work fine for my session, but these flags should be the first to disable if you run into problems.

• chrome://flags/#chromeos-video-decoder - this flag enables the new Chrome OS video decoder pipeline for hardware accelerated video decoding. This feature is stable enough for most devices, but if you run into a green or black screen when playing video, disable this flag.

• chrome://flags/#enable-service-worker-on-ui - by enabling this flag, the bulk of service worker code in the browser process will move from the IO thread to the UI thread. This is part of a big initiative to simplify Chrome’s IO threads, which can boost performance.

New Crostini features

Crostini on Chrome OS has been progressing quite nicely over the past few releases, though there are some important features that are missing. The following list of flags fills in some of these holes.

• chrome://flags/#exo-pointer-lock - this allows Linux applications to request a pointer lock, i.e. exclusive use of the mouse pointer. This is absolutely necessary when playing Linux games on Chrome OS.

• chrome://flags/#terminal-system-app - enable this flag to bring the upcoming Terminal system app to Chrome OS, which features a slick dark theme, terminal tabs, and various settings to tweak the terminal app experience. See screenshot.

• chrome://flags/#crostini-disk-resizing - if you need to increase or decrease crostini’s disk space, this flag will give you the option to do so. You can find the new option in the Linux (Beta) section of Chrome OS settings.

• chrome://flags/#crostini-port-forwarding - this feature opens up the host port forwards to user defined ports in the VM. It allows users to add new ports and activate, deactivate and remove existing ports.

• chrome://flags/#crostini-show-mic-settings - this adds an option in Linux (beta) to allow crostini apps (like Audacity) to access your Chromebook’s microphone.

• chrome://flags/#enable-experimental-kernel-vm-support - this feature flag upgrades the kernel to bring Crostini to older Skylake Chromebooks like caroline. YMMV as this feature flag may not upgrade the kernel on your skylake device (including some caroline devices). if you have a Chromebook newer than skylake, there is no need to enable this flag.

• chrome://flags/#crostini-gpu-support - before enabling this flag, verify if crostini GPU support is already enabled by default on your device. Launch the Linux terminal, install mesa-utils via sudo apt install mesa-utils, then run glxinfo -B. If the device line displays virgl, then crostini GPU support is already enabled and you do not need to enable the flag.

• chrome://flags/#crostini-usb-allow-unsupported - if you have an unsupported USB device that you need for crostini, this flag will allow your Chromebook to mount it. Enable at your own risk!

The “I want new pretty things” corner

Want to experiment with new redesigns? These flags adds extra eye candy to Chrome OS, apps, and various Chrome components. Gimme that Google Material theme!

• chrome://flags/#files-ng - this will replace the existing file manager with the completely redesigned file manager built using WebUI and Google Material theme. Disclaimer: the Dark UI everywhere enthusiasts won't like this. See screenshot.

• chrome://flags/#help-app - This brand new SWA app, called “Discover”, completely overhauls the Help app experience, featuring a slick Google Material theme with nice Google-y illustrations. This app also merges perks from buying a Chromebook, like free Google One storage for 12 months (YMMV). See screenshot.

• chrome://flags/#app-grid-ghost - when dragging an app around in the launcher app drawer, there will be an outline of where the app icon will be placed when you let go. See screenshot.

• chrome://flags/#enable-cros-virtual-keyboard-bordered-key - want to make your virtual keyboard look more like a physical keyboard? This flag puts bordered keys in the virtual keyboard to give it that “keyboard” feeling. Note that this is only works with the English keyboard for now. See screenshot.

• chrome://flags/#tab-outlines-in-low-contrast-themes and chrome://flags/#prominent-dark-mode-active-tab-title - when using a dark theme or entering incognito mode, these flags will help improve the legibility of the tabs. Should be enabled together. See screenshot.

• chrome://flags/#enable-query-in-omnibox - this will simplify the omnibox to only include your Google search query instead of the full URL. I like this one personally, but it may not be to everyone’s tastes. See screenshots.

• chrome://flags/#ntp-realbox , chrome://flags/#ntp-confirm-suggestion-removals , and chrome://flags/#ntp-realbox-match-omnibox-theme- these flags adds a "real" search box in the middle of the New Tab Page which accepts inputs directly. Previously, clicking the search bar will move the input to the URL bar. The suggestion removal flag will allow you to remove suggestions that the realbox outputs. The last flag allows Chrome themes to match the theme of realbox to the omnibox. See screenshots.

• chrome://flags/#enable-md-rounded-corners-on-dialogs - love rounded corners like I do? This flag makes dialogs rounded to match Google’s material theme. See screenshot.

For the Artists on Chrome OS

Palm rejection has been a major pain point for some Chromebook owners who draw art on their device. Although it has improved in recent builds of Chrome OS, a lot of users wished it could be better. Well guys - wish granted.

• chrome://flags/#enable-neural-palm-rejection and chrome://flags/#enable-heuristics-stylus-palm-rejection - these flags are an absolute must for users who spend time drawing or handwriting notes on their Chromebook. This improves the palm rejection significantly! Note that this does not work on all devices and will not work with external drawing tablets. If you're not using a Pixelbook or a Pixel Slate, I recommend leaving the neural palm rejection flag alone.

That's about all folks. Enjoy the Chrome OS 83 release!

Last updated: 5/31. Added fully gestural navigation flag in Tablet Mode.

How to do something with chrome android flags or other things at chrome://chrome-urls/ , maybe accessibility settings so I don't have to read the top comment on YouTube

I don't care if it makes YouTube look like reader mode, or anything else as long as it works. disabling comments completely would be ok also, I can open a separate mobile browser if I want to go to the URL and view them. note that Google has still not added any extension support for Chrome Android. as long as i can access m.youtube.com with the aforementioned, that is what I'm looking for. thank you, anyone who can help. I have no programming experience so I couldn't deduce what might work at the chrome urls page

Look here

Yes I know this is a chrome browser feature and not ChromeOS specific.

What are some flags that genuinely improve the browser performance and/or UI without adversely affecting battery consumption?
