Re: applock and smart app lock does not work on 5.1.1

Question

Hi @omdavice @wantboost When turn on the sony only the red led light flashed multiple times. This could be because battery was fully drained or there
was a problem with the boot. If you press the 3 buttons Power, Volume down and Volume up for about 8 seconds and then release them, the sony logo would appear. If this doesn´t work, you can also first run a backup of the device information like this: http://talk.sonymobile.com/t5/FAQ/Backup-amp-Transfer/m-p/407253#U407253 Then try performing a system repair using PC Companion: http://support.sonymobile.com/gb/tools/pc-companion/ This will factory reset your phone and erase all data. You might need tocharge your device for about 1-2 hours before so the device has at least 80% battery. Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device). Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process. If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP. I hope can be useful.
Best Regards,

My Xperia ZL have an strange battery behaviour. It started with a crazy battery indicator, for example, sometimes it is showing 75% of battery, then I start to use some app, and the battery drains to 50%, but right after I close de app, the battery shows 63%. So I've never been able to know how my battery is going for sure. Sometimes it is showing 35%, then I just use some app for a few minutes, the battery goes to 15% and suddenly the phone turns off. But when I reboot it, it is showing 30% again.
To charge the phone's battery, I must have luck, because it looks like the phone choose when it would like to charge the battery. The problem turns worst when the battery drains totally. The battery simply doesn't charge, the phone turns on and off constantly. When I plug the battery charger, the LED indicator glows a weak red light, then the "SONY XPERIA" appears, and then the phone turns off, the cycle repeats if I let the battery charger plugged in, back to the weak red light.
Does anyone here had the same problem with Xperia ZL? Does a simple battery change might resolve this issue?
Thank you!
