I do not own this phone, but the Compact version, however I have tried both models extensively. I have been VERY pleased with the phones, but when I started playing PUBG Mobile I detected something odd, that avoided me to aim properly, sometimes the touchscreen wouldn't track the touches when they are very slow or precise.
I could try this in the XZ2 (not Compact) as well, and there's definitely a problem with the screen sensitivity, I'm not sure how to define it, but it feels like a dead zone that moves with your finger. The phone will not detect small movements, kind of a precision problem. The tracking is just not good enough.
I have a video and pictures to demonstrate the issue, comparing the sensibility to my other phone (Galaxy S8):
And a picture:
I'm returning the phone, and I'll buy again if Sony fixes this via software (I hope they will!). I will gladly replace my S8 with this XZ2 Compact if we ignore this problem.
Comments are welcome.
