I had been using Meizu m3 note for the past few months but after installing the OTA update 5.1.11 G in M version my phone is charging very slow, it usually takes more than 5-8 hours and while on  a 4G network it doesn't charge at all. It's not battery calibration error.
At first i thought it was an error in thefirmware but the problem with m3 note is that i cannot go back to older firmware.
So i had to update it with higher stable version of Chinese firmware5.1.11 A and to my surprise the problem still persists albeit I was able to charge faster in Chinese firmware.
Should i wait for the next global firmware or should I go to the service center.
Any suggestions are welcome.
