I recently bought an ipad mini 3, 64 gb model on Powermac. It's brand new,sealed with warranty. The problem here is that i've been experiencing some lag in some ways when im using the ipad. Like when i'm rotating it on imessages, app store, or when i'm shifting from safari to home(using assistive touch) its only smooth on home and in apps..thouh somr apps still doesnt have the smooth rotation. Also, there are times when i open the camera and i try to take a picture with it, the first picture doesn't have a shutter sound. I just want to know if it also happens to people who're using the same device as mine..or atleast with same processor. I'm just a little frustrated because i expected to experience a snappy performance(though it is also snappy in some ways too) because it has the a7 with m7 coprocessor and it just came out(though i know that it has the same features as the mini 2) and its expensive enough for me. Plus given the fact that i have its on 64gb model and i barely put apps here( i only have 27 apps) i've already tried resetting its hardware by pressing the home and lock at the same time. Still the same. Its running ios 8.1.2 btw. I guess the games are okay. Really fast, smooth and all.Idk if ios 8 is just too high already for my ipad or is this a hardware damage? I want to know so i can have it replaced with a new one.
