    Device is Samsung Galaxy Tab A 7.0 (2016) 4G LTE (SM-T285), running Android 5.1.1 (Lollipop), without root.

    Device suddenly lost network coverage (not the first time), and flight mode did not solve it (not the first time, also), and the only way usually was to restart (power off/on).

    Usually that would solve the problem.

    This time, the same thing happened, and upon restarting the device, it spent a long time at the Samsung logo/splash screen (which is abnormal), and when it finally reached the lock screen, it took a while before the entire screen was loaded (wallpaper appeared first, then the time...). Upon entering into the home screen, some (not all) widgets were missing (noticeably the custom downloaded ones).

    Opened the usual apps to pick up from where I left off, and those apps ran as though it was the first time (as if it was just installed). App data (that was stored on internal storage) was lost. Other data (SMS, pictures) were intact.

    My immediate concern/focus right now is to recover the lost data, either by fixing this abnormality (safe mode/guest mode, maybe?), and if that fails, at least recover the lost data (preferably without requiring root).

    Any ideas?

    Only that since this is a computer, you should always have a current update - but it's too late for that now. There was a glitch in storage, and all the data got wiped. Since it's solid state, not magnetic, even a lab with an electron microscope will help. And since it's internal, you can't use PhotoRec on it. So no, no ideas on how to recover your data that wasn't synced or backed up.

    I don't know whether the data is actually deleted or I actually stumbled onto a separate "sandbox" (something like guest mode...?) because only specifically the app data was gone (so far). Any ideas about this abnormality?

    If not I would have to presume that the data is deleted, and I would have to recover it, and that would preferably have to be done via PC to avoid overwriting the deleted data.

    Any ideas?
