Sometimes after using the camera, the taken photos will just disappear.

Often my screen will freeze up and the ohone becomes entirely unresponsive until I turn the screen off and on again.

Sometimes the screen won't even turn on at all and will then suddenly unlock and register every single swipe and tap I made on the off screen registers at once.

Then sometimes when idle the phone will just randomly crash and reboot.

A genuinely awful experience I have to say.
