Parity Signer - android specs

Setting up air gapped android. Load parity signer but can’t open app. Says “insufficient security features available on this device”. It’s an android 11- go edition. (Cheap gen 3 tablet) is this tablet not compatible? I could not find min specs needed… help please

I think that the right place for the question is Github repository, for sure including as much as possible information would be helpful to debug and solve your issue.

Ok thx
