I got my ZF10 on launch. I have been using it since then, I like it a lot, but no USB 3 sucks. Other than that, is perfect.
But then, Android 14 came.
It added literally nothing new. I can't think of a single thing feature that I'm using that wasn't on 13 already.
I fact, it got even less. The swipe from bottom to switch to the last or the one before app is lost. I would be reading manga on an app, then switch to WhatsApp to talk to someone or Instagram or telegram, and all I needed were a few swipes.
Now, if I want to write to someone, it's faster to just swipe to go to home and relaunch any app than swipe and look for the app, since you can only sweep and switch between two apps.
Another problem I got, is that a week or less after updating to Android 14, I got a massive burn in the middle bottom of my screen. I don't know how that happened, since I don't use any app that has any white or bright square there, and the apps with bright colors are usually everywhere on the screen, not just there.
The phone feels a bit laggier as well, don't know why.
