My older sister recently complained to me about being tired of all phone notifications, and was asking me how to block ads on android. Although I'm not tech-savvy, I realize these very basic tips might not be common knowledge to everyone. So, I thought I might as well share a few simple tricks.

1. Stopping your data from being collected
   Last year, my own phone was bombarded with spam emails. I decided to stop the problem altogether. I learned that there are services that scan which companies collect data about you, use it to send spam emails, and then these data removal services send requests to remove your details. I might not have explained it well, but I think this reddit post does.

2. How to block ads on your phone
   I personally find them very annoying because you hear sound, you look into your phone and instead of messages from friends there is some unnecessary ad. Luckily, they are easy to block.
   Go to Settings > Apps, find the app that's spamming you, tap on 'Notifications', and turn off 'Allow notifications'. This should stop the pop-ups from apps.

3. Blocking unwanted text ads
   If you get a text from a number you don't want messages from, you can usually block it right from the message by choosing the 'Block' option. It’s probably one of the easiest and cheapest ways.

4. Dealing with spam emails
   Gmail has quite an effective and easy-to-use spam filter. Marking email as spam should definitely be your first step. I believe this redditor wrote a few more good tips.
   I know these are very basic tips on blocking ads on android, but, as I said, some people don’t know how to do even that. So I hope it helps. And If you have tips to add, please share.
