I'm using galaxy A70, I have facing problems with the lock screen images. When I set a colourful wallpaper is nice and not a problem but Set a solid wallpaper it showed differently.
When I unlock my mobile that wallpaper is changed into narrow lines, cross lines but I was set a solid wallpaper. When Increase brightness that time I was facing this problem other wise ok.
Once I entered in no issues at all. Only issues on the lock screen
report this to samsung by going to "get help" page of this app and clicking "send your feedback.." to let them know of this. i also recommend taking it to a service center, in case its a hardware issue
