I am using z fold 4 for past 1 year and that too without any problem. But yesterday my phone all at once lost its big screen. A black line has occurred all through its hinge area. This is something unexpected as this happened while openening the phone. This issue must be resolved as after paying such huge amount for a trusted brand product such things happening is very hurtful. I am looking forward to samsung help and r&d, How can samsung help me here! Moreover the touch features of the big screen are not working with fingers, only sPen works on the screen now. Kindly get me out of this trouble. Such a waste of money if this problem is not resolved.
