Hi.i m using app lock for 3 years .it helps us to hide the pictures n videos .i works good but once my phone was having some problem in speaker.i went to the service centre and they submit my phone nd said u can take back ur phone after a week .i agreed nd gave them my phone.They reset my phone due to which all the apps which I downloaded got uninstalled.Then I again install applock on my phone but my photos which are earlier hiden in that app could not be recovered although I had given them my email.I email them that ask the query that I could not recover my older pics but they didnt help me.so I lost all my photos .Which really disappointed me.??
