Sony Canada stops Android Marshmallow update for Xperia Z5 due to Play Store bug
A bug affecting the Marshmallow update for the Xperia Z5 is bad enough that Sony Canada is pulling the update for its users. One of the big issues caused by the bug is the Google Play Store crashing, even after cleaning all app data or cache. Some users can’t even open the app at all. There’s no specific date yet when the fixed version will be up. At the moment, the fix is to do a clean install of the firmware again. What users of the Z5 and Z5P need to do is clear the data of the Play Store. Head over to Settings > Apps > Show system > Google Play Store > Storage > Clear Data. From there, proceed to Settings > Location > and then move the slider to the OFF position. After that reinstall Android.
