- best phone for 130$ (second-hand)
if you can find a second-hand model, i definately recommen you to buy it, its a steal for the price. but there is one thing that bothers me, its the camera quality, but man if you dont care about taking good photos, just take it. snapdragon 870, 120hz amoled screen, great for budget mobile gaming. also, this device have many custom rom/os for you to try and find what you like best
Pros- cheap price

There's only a few kinks. For one, I wish MIUI chose which process to kill to save on battery a bit better than it currently does. It took a while to get Snapchat notifications to show as a result of that. Secondly, the navbar buttons could use a bit more adjustment than MIUI allows. Lastly, and this is the biggest issue, MIUI on the China releases of phones doesn't allow you to change the launcher to anything other than what Xiaomi approves of. So you're basically stuck with either the Poco launcher or the stock launcher. I couldn't find out any way to get the Google news feed on either of them so that was a bit of a shame. Other than those kinks the phone is great.
Pros- Display

Even the most demanding game runs smoothly, it doesn't tend to overheat in heavy games unless you push it too hard. The cameras take very good photos and you can improve it with the GCam. The sound is excellent and Dolby Atmos works both on its 2 stereo speakers and with wireless headphones.
