Restored from Sony Xperia X (F5121) to Sony Xperia X (Dual F5122), but never had the same, mostly smooth experience again!
I don’t know where to start… Here are some of the symptoms: The phone answers calls, but Android apps crash most of the time. Connections to the Jolla store and the Google store cannot be established anymore (worked for a while, i.e. the installation of the apps worked). WLAN connects, but after a while no more traffic! The installation of keyboards with other languages does not work anymore.
Any ideas how I can solve these annoying problems?
