    A few days ago, my XPeria Z3 kept hanging and showing black screen when it hanged. Even worse, the phone screen would sometimes go on the fritz, with whatever is on screen suddenly shaking and undulating, or it would show white noise static. Sometimes, the hang takes a long time to get resolved, sometimes it goes away when I lock and unlock the screen. Most of the time however, locking the screen also makes the hang worse.

    I've taken it to the official Sony service center in our area, and the repairman flashed and reinstalled the firmware to the latest version.

    A few days however, the problem still persists. Thinking that it must be some incompatibility between the OS and one of the apps, I tried switching to Ultra Stamina mode, so that only the basic apps will run. Unfortunately, even in this mode, I still experienced the black screen and the hanging.

    Is anyone else having this problem? How did you fix it?
