PIN Setting is too aggressive

[thisispav]

few use cases where this happens

1. even when I flick between 2 apps, Bitkit is stays in the background, for 2-3 seconds, I have to put in a PIN again
2. when click on a headline and want to move back to the app only few seconds later, you have to put in the pin again.

perhaps some buffer allowance of a few seconds would improve the UX
