Meizu is the bad phone that i had ever used.So bad ram management and global stable firmwares are with bugs and the most of products are with MTK chipset even vivo and oppo use SD instead of MTK.Look like meizu developers are working for chinese users on the other hand they are neglecting to global users.Their business is only for chinese not for global.Stop exporting your phone to global.Import only in china.Many of global are cheating on you.Please leave from global and never comeback.Vivo and Oppo are better than Meizu.Shame on you Meizu.There are so many things if i write about of meizu.Sorry for nooob english skill
