Few days ago I turned on Possibilities for developers. Until that event my Xperia SP was working without any problems. Now during phone calls my phone is not able to launch keyboard (for example write text messages or browse internet) and not able to open some apps (in Settings none of apps is able to be open) all during phone calls. Other times it is working as it has to. I tried to turn Possibilities for developers OFF, unfortunatly nothing have changed. How can I deal with this problem? (All updates of software were official through Sony PC Companion)
Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
I suggest that you to run your phone in safe mode for a while to check if you still experience this. If not this may be caused by any downloaded application. How to boot into safe mode?
I use Clean Master...Is it caused by using this app? I was using it few months without problems, it happen just lately.. So suggestion is to remove Clean master?
well, after deleting AVG antivirus and Clean master nothing changed. I am able to open keyboard while calling, but after locking screen and ublocking again, keyboard is unable to be open again...
