I switched from Windows Phone to Android. I brought 2 Moto G LTE and have it for about a week. The scrolling for phone is not smooth at all, it is jerky. Touch sensitivity is not great either, I have to press on the screen harder. I installed the usual apps like Facebook, Facebook messenger, Skype, Line and couple games. My phone constantly running at 75% or more of ram, I have to constantly using Clean Master to release the ram. I searched forums and website and following many advises, but no improvement. Should I reset the phone or return the phone and asking for replacement? If I choose reset, is there a way I can backup everything so I do not have go through the set up steps for all the apps? Please help, I am newbie to Android OS.
