Hi guys, I have some problems with my iphone 5s that would like to state here hope to get the sultions for them: 1- My iOS version was 7.0.2 and I installed some good apps on it, then I updated my iOS to version 7.0.3. After that when I tap some of my apps, first page of them appear and immediately vanish and don't go to the app. Does anybody know how to solve it? 2- At what percentage I should recharge the buttery? Thanks.
