iPhone help if you can.

[Paper Roses]

I have an iPhone8 help that is serving me well. In the past 2 weeks or so, the screen is always black. Very hard to read anything. I went to ..settings.. and made sure it was set to "light. It still is almost black. I have to use a magnifying glass to read anything that appears.
If I go to the local iPhone repair shop for help, they will charge me $30 to answer my question and $ 60 per hour for any repair.
I have gone to
settings and it always shows "light" and the screen is still so dark I can not, without a magnifying glass under light to read anything.
Is there a way I can lock it so the background stays"light" always?
Please let me know if you have had this problem. It started about 2 weeks ago. I have no idea what to do.
Thanks for any ideas, I'm a iPhone/computer idiot and need help.
Appreciate any help you can give me.

1. Possibilities:

1. the back light may be bad

2. some buttons may be lowering your brightness ( this might be totally off base)

3. depending on your iphone OS version, you can create an shortcut called automation to periodically increase brightness to maximum

2. if you decide to replace the phone,

let us know. sometimes the Apple Store is better and sometimes not. your circumstances and wishes can be discussed ))

3. Not the same

problem I had with my iPhone 7, but I went online to Apple.com and followed their easy instructions. Sent it in for repair of battery and it didn’t cost a lot. It’s worth a try. I’ll look for the correct link

FOUND IT!! 😊

5. Push the bottom round circle button and say

7. That's exactly what I do!

8. If it never lights up, could be a backlight failure.

My 8 works fine. Crossing my fingers. Rarely, the gravity/rotation sensor locks up but a restart fixes it.

If your screen were completely black, it might be a loose wire. Doubt it. Maybe a "genius" can run diagnostics vis the lightning port.

Good luck! 📱
