I downloaded this app 3 months ago for my LG device. When I opened the app it showed me tap here to root after 5 min my mobile got rooted. First I thought that it was a nice app for rooting the mobile but when I rebooted my mobile and then checked for root it told me yhat the your mobile is not rooted. I tried doing this 2-3 times but the result was same. Not only it was removing root when rebooting but also it was damaging my OS. After this app I tried kingroot app which is best for rooting the mobile as off I have seen. Ut is not recommmended to use kingoRoot app for rooting the mobile instead use kingroot( not on playstore) which is best for rooting. KingoRoot damages mobile OS. The overall interface of the app was quiet good but for us the interface does not matter as we want to root are mobile in proper way.
