i am really frustrated now. Actually i am using my jio sim in my meizu m3 note L681H and at first i  did not observe any lag issue in this device. But then i just put off the sim and i did not use internet in this phone almost 7 days. And now i am just using the internet in this phone and now it lags really bad or you can say hang issue. there has lots of animation problems and lots of lag for this reason i am very frustrated. Has it any solution?
