I just purchased a Toshiba Excite 10. I was surprised when I attempted to update manufacturer-bundled software and found that I couldn't because it wasn't installing through Google Play.

Is there a way to make my tablet understand that an app downloaded or upgraded through my OEM is just as safe as something downloaded through Google?

You should go to Settings -> Security and check the option: Unknown Sources (or something like that). then your tablet would allow you to install apps from everywhere.

This option should obviously be turned back off when you're done. – pzkpfw Aug 29 '12 at 12:20
@bigbadonk420 Why? I don't see any reason to do that. – Richard Borcsik Aug 29 '12 at 12:34
Isn't this a security hole, allowing anyone to install apps on my tablet? – lacqui Aug 29 '12 at 13:29
@lacqui maybe it makes security problem, but when this is not checked, you are never able to install any app from other sources than Google play. And, I always turn this option ON without any problems, because anyway all apps require your permission to install, except when you have rooted your phone and some malicious app installs another app silently! – yrajabi Aug 29 '12 at 14:21
Because there's no reason that the default option should be to allow all packages from anywhere. If you need to install exotic packages, it's better to disable the protection then, instead of leaving it always off. It's like asking "why should I have the safety on when using guns, I'm not an idiot". Why not use it when it's there. You have no way of knowing what situations your tablet will be put in (other people using it etc). – pzkpfw Aug 30 '12 at 15:12
