Android Pro app resets completely

[Arno K]

Ok, I think because it is/was convenient to store data there due to system restrictions invented by Google some tims ago, it was Android 4 or 5 when they decided not to let any app store and read data anywhere on the device. Now apps need special right to access folders other than their own. Perhaps Tim can give the prime app a folder for storing content now.
Nevertheless we found out why your Android prime loses data from time to time.
