[Q] Xperia Z Ultra automatic switch off and TOO LAG! - Sony Xperia Z Ultra

My xperia Z Ultra always switch off automatically and I have to switch on it again and again. Also, it is super lag and looks like slow motion. What can I do?

Does it restart continuously or you can use your phone for certain amount of time? Can you go to settings, does phone respond to your screen touches?

[Q] Disable Automatic Brigthness

Hi,
I've just bought an Xperia Neo with 2.3.4 firmware.
I'd like to know if there's a way to disable Auto brightness dimming.
In the Settings--Display--> I can change the brightness level, but the auto-dimming remains active.
There's a way to disable it without rooting device?
Widgets and application from the market doesn't disable auto dimming...
Thnx to everyone!
WZ
i would also like to know this, it's so frustrating, when i accidentally put my finger over the sensor it dimms the screen so i can barely see a thing

Turn off keyboard backlight

hello, my xz1 compact inst root and I have some questions:
I - Anyone know an app that reduce or turn off keyboard backlight, and that reduce absolut low light numbers? I do not like how this phone is bightness at night and not satisfied with the most famous apps on play store or night mode.
II - When stamina mode is turned on my keyboard starts to act strange like buggy and delays between touch and real write. Does anyone know how to solve this?
III - I'm using OnePlus app for gestures and not satisfied with my keyboard app. I'm using Gboard didn't like chromma and Swiftkey, does anyone recommend an app for bigger board since I had no navigation bar on screen? thank you!
1) CF.Lumen has a great red-light night mode, that makes the phone comfortably usable in utter darkness. The lowest brightness level on this phone is definitely a weakness.
2) It's likely Stamina Mode reduces performance to lengthen battery life. You might try a simpler, more lightweight keyboard, maybe? I think there's one called 'Simple Keyboard' that is really lightweight.
3) You can resize both Gboard and Swiftkey to be pretty large, easily taking up more than half of the screen.
