Basically MEMEUI (MIUI) is Buggy UI so forget About Bugless update Some bugs are fixed By Them but Some aren't Fixed By them which we need to Fix them as A Temporary Jugaad and I Think that 10.3.4.0 is a good update as so many bugs were fixed by them and Battery after Calibration is working better than previous one just a main thing with MEMEUI we need to use is the Technique and Jugaad then it will work fine

bro.. it's one of the worst update!
