Hi, I've looked at various forums and counseling centers, but I haven't found the problem I have yet. In short, I have had a xperia Z5 for about half a year, and sometimes it happened to me that the display flickered at maximum brightness, or the most gray color, and today it is almost always. It is also interesting that this is sometimes affected by the stamina mode, when I turn it off the display stops flashing. I tried everything from various apps to uploading an older android. Now I have only one complaint left. Should I get it right, or is there still a solution?
