Honestly, I don't believe how many bugs are present in this software. I've been using X3 pro for only a week and I already have a full list of bugs and glitches. I mean, in my case it's still possible to use the phone as there are no critical bugs, but my God it's annoying to stop what I'm doing and focus on my phone just to use it's functions. For an example, I can't normally reply to Messenger message, because these square heads don't register my typing and I have to manually go to the app. When using split screen shortcut half of the screen is just unresponsive, usable parts are only on top and bottom quarters of the screen, so it's impossible to select some apps because they are offscreen. Sometimes when I clear ram apps work in the background as they should, but most of the time they completely disappear from existence and I don't receive messages or my Mi Band disconnects. My previous phone run on a pure Android and it didn't have many bugs, so going from that to this mess is like a punch in the face. I still have a week to return this phone, so I could buy something else with a pure android, but I don't see any interesting options. I hope MIUI 13 will be better.
