I've just updated my Nexus 7 to v5 or lolipop or whatever Google's latest iteration is called.
The problem is non of the 'keep screen' apps seem to work on it now, including the one I had on the machine.
This is serious for navigating as the most you can hold the screen for using the settings screen is 30mins.

So if you're asked to upgrade don't, unless you know more about this stuff than I do ( not difficult)

And if you do know about this stuff can you help me with something that will keep the SkyDemon screen alive for more than 30 mins.
SkyDemon 3.2
Cheers
John
