Honestly, it's a lot of little things that are coming together that other companies like Samsung are doing better. Connecting to Wifi takes ages, and if one try fails, starting the next try takes forever. Also, some apps don't support floating windows, there are also some quality of life settings that I miss every now and then. And then there's some other minor things that I just notice in the moment and immediately forget about again lol. But I definitely appreciate that they don't try to push their own app store, like Samsung, for example.

Personally I've just had issues with pocket mode not registering and combining that with liking tap-to-wake, lift-to-wake I ended up calling my emergency contact way too many times. Still not fixed.

Also, I thought it was standard to allow for forward/backward by long pressing the volume buttons, but that option isn't available apparently either.

It's battery optimization is also a bit shite to be honest, however I don't know of any manufacturer that doesn't run afoul when it comes to that aspect.

Minor gripes really, but it feels like it could be more polished and while the UI isn't modified too atrociously, given the above issues I'm wary of what else they've modified under the hood.

It's unstable and crashes a lot. Otherwise, it's pretty much stock Android, and it's nice not having 16GB of extra Samsung bloatware.
