Hello, after receiving and updating via my OTA my Xperia X F5121 to Android 34.3.A.0.217, I started to have problems to turn on the screen, bone whenever I turned off the screen, when giving two touches to the screen or from the porpoises On / off the computer did not turn on and the only way was to restart the computer, but when the screen was shut down again, it was impossible to turn it back on again, reinstall Android using Xperia Companion - Software Repair and continued the problem until a reinstall Complete in clean, no applications and enable one by one the functions, until the fault appeared when enabled on the screen with two touches to it, when enabled this function, the screen as it tries to turn on but it goes dark, reboot The computer disabled this function and my Xperia X works normal. It seems that this function causes some conflict with the new version of Android 34.3.A.0.217. I post this so that if someone else has this problem, find the solution, until a patch appears and solve this novelty.
