a. Go to phone setting->security->device admin and uncheck HI App Lock

5.0 out of 5 stars fab little app 15 Jan. 2014
By Tjayne
Verified Purchase
i have this app on both my kindle and my mobile. it works great by adding a password -which can either be in letters or sequence. you chose which apps you make private for example i have my memo, messages, play store, internet and my files private but leave my numbers visible with no lock on. this way it keeps prying eyes from reading my private things whilst still leaving the phone accessible for use. also they cant run up and bills for down loading lots of expensive apps! works perfectly so far.

I recommend that you try this app, it's great to protect apps you love from sneaky and nosey people! Great for a kindle fire hd, and it's free, so you should definitely get this application now! :)

4.0 out of 5 stars AWESOME BUT COULD BE BETTER!!!! 23 Nov. 2014
Verified Purchase
This is a great app with many fab features such as disguising the HI app as a calculator and fake error messages for nosy siblings trying to get onto your Facebook™ account, however, the downside is that these are all on the 'upgrade to full version'. Still good though!!
