r/samsung on Reddit: The Samsung S21 processor is the best Exynos in Samsung history
February 14, 2025 -

I bought an s21 in 2024, the motherboard of my s9 was burned, the exynos of my s9 was heating up, and the battery didn't last long, so for the purchase of a new samsung I was afraid about the samsung chips, so much so that I had aimed at the s20 fe with the snapdragon, but I decided to give a chance to the exynos of the s21, the reviews spoke well of it.

Guys, it's a masterpiece, it never heats up, super fast, with 120 hz activated the s21 can easily hold up in 2025 with phones released now, I think samsung hit the mark that time..

Funny that the s22 has returned to having a mediocre exynos, Samsung is really strange what do you think? Do you agree?

I miss the s9 screen though, that resolution was crazy

I don't think S21 Ultra Exynos can upgrade it's CPU to a better Snapdragon though. I would like to upgrade the S21 Ultra phone without getting the S22 Ultra platform which now operates in a lesser of a phone's component space that was taken up by a pen holder.

3 weeks ago - The processor and thermals on that phone are crap, DO NOT get a S21U or S22U those have the horribly efficient chip. Get a S23U and up ... I used my s21 ultra since 2021 until last month when it fell and screen damaged. Camera had alot of glare reflecting off the light compared to newer phones.

May 18, 2019 - Camera and processor, basically. ... The big differences are laser autofocus (last year's camera had trouble focusing), and a new sensor. The number of cameras has also gone up but I'm struggling to understand what the new one does. Could overall be a decent improvement. ... The main one is the same camera essentially. Nothing ground breaking, just a tiny marginal improvement, I doubt it'll even show up in comparisons. S21 Ultra ...

r/S21Ultra on Reddit: Are newer devices really that much better than the S21 Ultra?
March 3, 2025 -

My wife has an S22 Ultra. It's alright. I don't really think it's all that worthwhile of a device to upgrade if you already have an S21U, unless you get a really good deal.

I had the chance to try out an S23U recently.. And honestly, I wasn't impressed that much. If anything, it almost seemed like a downgrade, particularly in the camera department. Everything seemed to be off colored and grainy. My wife seemed to think so as well. Tried different settings... Nothing seemed to improve it much.

My wife's device, the S22u 256gb with 12gb of RAM, is incredibly laggy. I've never had this problem with the S21 Ultra.

That makes me beg the question... Are these newer devices really worth upgrading to from the S21 Ultra? There seems to be so many issues with newer devices.

2 days ago - S21U had the best design, screen looks exactly the same to me, camera had minor niche use-case improvements (like low light), and performance doesn't mean anything now in modern chips (everything can run the usual 5 apps everyone uses).

It might be possible for me to get hands on an S21 Ultra sealed pack for approx 320 usd (29k inr). You think this is a good deal? And does it makes sense spending this on a phone which effectively does not have any OS updates coming? I have always wanted to get an Ultra but never got around to doing it, and this might be an opportunity. I'm checking if I can get a similar deal for s22 ultra, but it seems unlikely.

Let me know your thoughts please.

I have an S10 right now thar works perfectly but feel I should upgrade before issues arise. Do not care about the latest features or acquiring status by having the latest cell phone.

Is it a bad move to purchase a galaxy s21 right now in April 2024 It's unlocked. From backpage.com 168 bucks

Is this the right move?

Iโ€™m planning to upgrade from Iphone Xs in early october. My questions:

  1. How does it hold up today?

  2. What are the pros and cons of owning it now?

  3. How often does it lag, stutter?

  4. What phone would you recommend if you donโ€™t recommend buying this phone ( Samsung S21 Ultra)? You can recommend any phone brand model except Xiaomi ( because I donโ€™t like itโ€™s os)

I use my current phone for Social media, work, browsing and sometimes for games My maximum budget is 350โ‚ฌ euros

r/S21Ultra on Reddit: Suggest a android as good as samsung s21 ultra but not samsung.
May 26, 2024 -

On the end of May my s21 ultra (exynos) had a big update, and ever since it has freezed unexpectedly and afterwards had multiple reboots. I had it examined in a local phone service, but they found nothing. I have had enough of this, once it stopped working in a middle of a super busy night as I was planning the night with my friends.

Before I was a Samsung ultra fan because my previous s20 ultra had proven to be a reliable, smooth and fast phone. The issue I have encountered now has shaped my thoughts, and I no loger want to have anything to do with Samsung.

Please suggest a android phone you find as good as Samsung Ultra, but more reliable. In the best scenario also as good camera, but that's not the main thing. I have positive experiences with Xiaomi, but I was thinking about One Plus although I haven't had one. Thank you!

January 2, 2019 - As someone who likes good screen resolution, i still fell bad that samsung decides to give fhd only to non-ultra models ... The changes I like the most is the 5nm process and Wifi 6E. Although I will wait for its refinement in the Note Series. "1st generation" of anything is often plagued with bugs. ... Possibility is note series this year might not come. ... Other than the processor is the S21 better than the S20 at all?

Is the S21 Ultra really an upgrade over the S20 Ultra? I know the S21 loses an SD slot, no longer includes the charger in the box and gets a newer chip but these things are minimal. In terms of features and hardware is there anything that, in paper, makes the S21 Ultra better than the S20 Ultra?

The camera getting a real auto focus system is huge. Better processor. Better screen. S pen compatibility. An extra camera. Improved space zoom. Adaptive qhd 120. Bigger battery. Way better design. I actually think it's a large upgrade. I know losing the SD card sucks. Charger too. But those aren't deal breakers for me. If I had the Note 20 Ultra, this would be a harder question to answer.

I have the S20 ultra and, despite initially swearing off the S21 year because phones don't change that much, I decided to trade it in toward the S21 ultra. Reasons are: I cannot stand the finger print sensor on my S20 ultra. It has, at best, a 50% success rate on 1st attempt, and frequently registers 5 failed attempts and kicks me to the pin entry. Hoping the rev this year is a lot better. Cameras have always been so-so. 100x is worthless, even 50x is not great. 10x is the absolute limit of bothering in my opinion but not what you really expect from a big fancy camera module; trying to eek out 10x from a 4x optical just isn't great--I really like that samsung is using two telephoto cameras in the S21 ultra to address how people have tended to take zooms--a smaller zoom at 3x and a larger zoom at 10x. Provides much better overall results. Original 108mp sensor and optics on the S20 ultra was kind of a let-down. It did improve with updates, focus behavior did improve with updates, but not to the level that such an expensive phone should. The improvements in the note 20 and then brought into the S21 should provide a pretty good improvement in the main camera overall. I haven't really used sd cards in years, so the removal of the slot doesn't bother me. The $700 trade in value plus the $200 accessory credits was $900 worth of incentives against the $1100 I paid for my S20 ultra (discounted price on Amazon), that it was a much easier decision to get rid of my S20 ultra. Generally speaking, the S21 ultra display is said to get a bit brighter in bright ambient environments. The S21 ultra has an adaptive refresh rate display rather than one that can only be locked at a certain refresh rate, which is potentially a power saving aspect compared to the S20--the actual amount to which this matters is yet to be seen. I was never blown away with the battery life on my S20 ultra, though I was never disappointed by it. Maybe the adaptive refresh rate on the S21 will bring it into impressive territory. The S21 has more microphones for audio recording. S21 also has updated camera modes (director video camera mode) and processing features (like single take--perhaps those will trickle down to the S20 series at some point, unknown). I think my S20 ultra has been a tank in general use, but I really, really hate the fingerprint scanner on it. That's reason enough for me to not recommend it to anyone at this point in time. While the S21 doesn't include the charger in the box, if you pre-order, you get more than enough samsung store credit to get one at no additional cost.
