I'd like to store all my Account information in it. Also using this same factory reset Android solely for cold/offline wallet(s) & google auth. I keep it in Airplane mode all the time and turn off airplane mode briefly when needed, then immediately back on.
This would be the perfect place to store this "vault app" or "safe app". As I only use the android phone with highly trusted wallet apps & google auth (currently). I use this device for nothing else.
I would also need the ability to back up this vault.
I also it needs to have very good encryption with no backdoors for the company who designed the app nor any hackers.
Thanks
