Many of my apps are protected by an lock app ('Smart Applock' - asking for a pattern unlock before access to gMail, install/uninstall, etc). As most of my apps are thus locked individually, I would like to have the convenience of a swipe-only unlock during normal use ... however, none of the app-locking apps I have tried offer protection just after boot-up! While the various bits of the system are loading, one can still access, say, gMail, and other functions for ~ 30 seconds.

To get around this problem of reduced security during the startup process, I was wondering if it would be possible to have a pattern or password unlock requested by the system once only, after boot?

Edit: one suggestion is to disable the 'power button instantly locks' and the automatic lock after sleep, which would mean that a password/pattern is asked on startup only and never thereafter. However, for the lock after sleep all one can do is select a time up to 30 minutes, not disable the auto-lock after sleep entirely. Is there a hack to extend or remove that limit?

  • Is your device set to lock when the screen turns off? If you can disable that then the initial unlock request should be the only one unless you manually lock it. – Matthew Read Feb 22 '15 at 16:42
  • Good suggestion - but there is still a timed lock that happens, and the maximum I could set is 30 minutes. Perhaps there's a setting I could set (in terminal) to remove that timed lock? – Simbamangu Feb 23 '15 at 8:13

You can encrypt your phone and it then will ask for a pin each time you boot your phone

  • Actually this is seriously counter-productive. After encryption, swipe is totally disabled and the device asks for a pin code every time you use it. – Simbamangu Feb 24 '15 at 3:26
