Android Pro app resets completely

[Jacob Wall]

Curious if anyone has experienced similar issues with their Android Pro app:
1. User apps disappear for no reason
2. Calculator settings are completely reset for no reason
3. Other similar loss of data/settings?

I have tried to reproduce the issue consistently, but with no success yet. Most of the time I will use the hardware calculator, but occasionally I only have the Android with me (Pixel 2, Android 8.1), only to find that the user apps I installed on there are gone and all the settings are back to factory defaults. This has happened about 3 or 4 times in the past two months, only on the Pixel 2. On another Android Device, Samsung Tab E (Android 7.1.1) I haven't had any issues.

Other observations:

1. Updates
When the Android app was recently updated, I checked and was surprised that all the settings and user apps were unaffected after the update, so I certainly can't pin this to an update issue, and I know I haven't purposely reset the calculator.

2. Resets
A Reset from the menu Calculator>Reset clears all user apps, but that is expected. A Reset also leaves the Serial number intact, and the app will re-connect to the Connectivity Kit automatically. During the loss of memory situations, I have seen the Serial number changed, and I'll have to go and choose "HP_Classroom" before I am able to connect to the Connectivity Kit again.

Interestingly, as I was typing this post and playing around with the Pixel 2, it happened again, serial number changed, everything reset. Attempting to reproduce is not yielding any results however.
