Good evening, I have a problem with my Xperia Z apps it shows that the date of every Google app 1/1/1970 1:00 am. I guess it happened since I update my mobile to Android 5.1.1, is there any possibility to fix it because I'm not able to install new apps or to use apps that access my location. I'm not able to roll back kitkat because no PC available around me. Thank you
