Apps that can alter the default security policy can be powerful and handy, but you need to know why they are doing it before you say OK.

I purchased the Unlock with WiFi app that Jerry recommended a few weeks ago. I haven't fully installed it to use yet because it asked to "activate device administrator". I wanted to be sure that was OK? What risks does it create to allow this type of access to my phone?
Thanks!
What an excellent question! Security on any smartphone is pretty darn important, and the simple fact is that most of the time when it gets compromised, it's because of something we did. I don't mean something crazy like installing cracked apps from a website you had to use Google Translate to read, though that's always a good way to compromise everything. I'm talking about changing device settings or just not using some functions because we don't fully understand them. The Device Administration API is a great example.
Originally baked into Android with version 2.2, the Device Admin API allows you to alter the remote or local security policy of your Android. We'll use my Unlock with Wifi app as a walkthrough of what that means after the break.
Have a question you need answered? (Preferably about Android, but we're flexible.) Hit up our Contact Page to get in touch!
