Okay, I have m3s already for about 5 months and I almost didn't had any problems with it but yesterday sh-t happened... I am really accurate person and I don't throw phones and ect., this phone didn't fall down even once. Also I am not phone gamer or something like that, I just use it check email, some social apps and make pictures, nothing special just regular user. I can't say that this phone heats a lot, but yesterday with heating started strange thing, color temperature started to change and on right side of screen (mostly) started come out red "lines". And more phone heats up them more lines and color temperature change is seen! Today I had googled​ this problem, and appears that I am not only one who had this sh-ty problem! Tomorrow morning I will go to shop (in France) where I have bought this phone and demand for a change or repair because I have warranty and I hope that it will happen really fast due to soon I will need to go for trip to different country for X time period so I need this phone! And I really don't want to make bad reviews to MEIZU phones, but if this situation will have bad impact on my side, than trust me you will get not so good reviews about your products on English, Russian and French community's​ (I would really hat to do it, but it depends on your service)
Thank You for Your attention!
