Those who are experiencing display issues like black crush,screen flickering in M52. Report error in samsung members application and also call samsung customer care and say to them about this issue. Otherwise they will not look into this problem. When i called them and They are saying that they does not get any complaints about black crush and screen flickering in m52. So i request everyone to call them and complaint about these display issues.
If they get plenty of complaints then only they will push an update to fix these issues.
