Having installed the HM7k app with Dongle on Moto play 6 (because my Galaxy Tablet is currently incompatible with the app) and got it working with a couple of locos I have experienced two app crashes. The app crashes to white screen and does not respond to a Forced Stop or Clear Cache. Only Clear Storage fixes it, but that loses all input data for 30 locos etc. Am I the only one to have experienced such an app crashes. Using other software, one of the first things to do is to backup/save the input so far. With many 'keystrokes' required for each loco and accessory, a crash is catastrophic and off-putting. What is the recommended method to backup all this add data? I have tried several general Google backup methods. All to no avail. Shouldn't there be a built-in save data/backup facility? I would like to keep a copy of the data 'off site' as a backup.
