The screen of my iPhone 11 got darker
Some time ago I noticed that the screen of my Iphone 11(64GB) got darker. Since it is nearly 2,5 years old I decided to buy new Iphone 11 (128 GB this time) but as I did backup from my old one the screen of the new one got darker too. I've already been to iDream to see what is the problem but after doing the diagnosis I was told that everything is okay (even with the old one). They told me that the light sensor is working and everything in settings is normal. They suggested that the problem may be in one of the apps I have on my phone but they didn't know which one. Here's my question, is it possible that it is because of some app and if yes do you know which one ? If not they suggested that it could be some problem with system that couldn't be explained. Can I do backup without damaging screen brightness of my new phone ?
