@Sasan123 What you said is right
Flyme 5 has focusing issue.
Many of bugs reported even i reported but no result found.
Flyme said they will optimize the camera focus in flyme 6 …and yes camera focus has improved alot.
You can try flyme 6 beta.
Believe me its good(flyme6)
@zoroflamingo quality sided its true, the 4th generation of MX devices has been the worst. However, firmware sided the improvements are not really “feelable” for all devices. Flyme 6 might not feel as nice for these older devices than for us with the newer/latest phones.
To get back on-topic:
Maybe order a replacement for the camera module. Its not quite expensive and should be worth the investion, even if you do not wish to keep the device.
