force close loop - unrooted

[Lithium2]

Hi, my phone today seems to be stuck in a force close loop. It pops up down the bottom of the phone in a black box 'forcing close of player' and 'closed?', every few seconds, exiting whatever app I am currently using. This only happens immediately after I turn the screen on, for about 20 seconds and then stops until I turn the screen off and then on again. I have not rooted the phone or done anything out of the ordinary. I did download a couple of apps from the play store and have since deleted them, but I still have the problem. I have read to clear the cache partition to fix this issue, but I believe it is in recovery mode which the Z3 does not have. I would prefer not to do a hard reset. Is this my only option?

If on KK try Settings then tap the 3 dots then Reset app preferences or if on LP Settings then Apps then tap the dots then Reset app preferences reboot and test

or try performing a system repair using PC Companion as this will often fix issues - This will factory reset your phone and erase all data so best to backup before you begin

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
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
