Hi all, I have Xperia ZL with latest . 101 and using Serajr 4.4 system ui. My stamina weren't working properly so I decided to reset and clear "extended standby mode control" Data. After that even I restarted my phone but it doesn't turn on anymore. I tap the stamina switch button it gets on and then when I go back to setting and then to power management again , the switch is off again. It's like the stamina doesn't start at all. Even if I go to settings-apps the "force stop" button is impossible to tap. But I can clear data.
It same goes with "low battery mode".
Sorry for bad grammar. Anyone know how to fix this?
