dear Asus,are you going to fix audio/video playback asynchrony issue?(youtube app).Im a owner of 3 devices(zenfone 5 a500cg,memo pad me 581cl and 572cl) please dont disappoint your loyal users ,instead to say make a factory reset,maybe will be better to release 5.1 one with fixing?dont say it me again.i made hard reset of these 3 devices twice already via recovery mode.and the problem still exist! I can give you some help-when i restart devices its ok and no audio delay,the issue appears every time when i speak via skype. We have problem with camera on me572cl ,after update to lollipop the camera just doesnt work,it freezes with black screen.just nightmare,also we have memory leak problem with all these devices-by using some time the ram usage increase and increase though all applications are closed and the system begin to use about 1 gb of ram and we loose the stability,device become work slow,the animations become laggy just like an old device,why?please focus on these 3 main problems and fix it asap!i believe in you,thanks
