Hey guys, so it has been good 20 to 25 days since I bought my new Nokia Lumia 720. I have even updated it to amber. I am generally very happy with the device and its offerings. But a constant issue I have been facing is that the OS sometimes stutters while opening certain apps. It doesn't lag, per se, but there is a skipping of frames while opening apps. Like when I tap on messaging tile, it doesn't complete its animation smoothly. It stutters a bit. Doesn't take longer time to open, works as it is supposed to, but that stutter is really annoying me. I thought this would be fixed in amber update. the OS does seems snappier after the update but the problem still persists. I have tried re installing the OS via NSU for retail, and did a hard reset, but to no avail. Do any of you face that issue?
