main con is that very low photo quality of camera and update

agree

So many problems in meizu devices software problem 4G is not supporting in india in meizu m3 note meizu accessories not available in the market and many more problems in meizu devices

which phone you have?  why you are dissatisfied?

On some point others are right about the processors being used by meizu compared to the Xiaomi ones. But the thing is, Meizu focuses its attention to their phone's Durability and Beauty (My basis here is the specs of meizu devices on their website. You can also read there some of the methods they used to build a Meizu Phone like heating it over blabla something etc ... ????) You can also reffer to the meizu phone's Camera quality, Screen Refreshal rate and Touch cell, Sensors, own features (OS).

mx6 is shit. can't unlock it bootloader to test anoter custom roms.

I agree

Then you would have chosen Xiomins Mi not meizu
now thers no point in blaming Meizu
yes but you can advice others not to buy Meizu device

bro in this price segment more other companies like MI give fast Processor snapdragon chipset and meizu only give mediatek chipset on there all devices

well devices are good as compared toh other devices in same price range.
But yes meizu is taking global users for granted ,they are developing flyme os for devices of other manufacturers all over the world but for their own devices they are not paying attention....Even there are not many devices too.Still Meizu doesnt care.
