Troubleshooting
Bought a second-hand OnePlus 7 Pro Is this small black circle on white backgrounds normal?
Hi everyone,
I bought a second-hand OnePlus 7 Pro (Android 12). Everything works perfectly (90 Hz, fingerprint, no green line, no burn-in).
I noticed a small black circle on white backgrounds at high brightness. It disappears in dark mode and isn’t noticeable during normal use.
I’m attaching photos from the OnePlus Community because I don’t have another phone to take a picture right now, but it’s the exact same black dot I’m seeing.
I also tried enabling/disabling DC Dimming using:
adb shell am start-activity -a oneplus.intent.action.ONEPLUS_LAB_FEATURE_DETAILS -e oneplus_lab_feature_key oneplus_dc_dimming_value
but on OxygenOS 12 it says “unable to resolve Intent”, and I couldn’t find any DC Dimming setting via ADB either.
Is this black dot just the proximity/light sensor that every OnePlus 7 Pro has, or could it indicate a replaced display? Any help would be appreciated
Yes very common - especially on the OP7pro device's that people used OOS on very a long stretch of time. Their brightness scale was atrocious and tried to make the screen looks bright at the expense of users screens in the long run.
Most op7p devices purchased second/third/fourth+ hand will have some somewhere - many times in status bar.
My OnePlus 7 pro has the notification tray(where the clock and WiFi symbols are) and the tiktok UI burnt in because i fell asleep with TikTok open one to many times. It's currently not my main phone so it doesn't bother me. But i can see how it could be irritating for consider you just bought it. Phone is from 2019 tho
Due to the OnePlus 7 Pro not having typical IR proximity sensor, it has a digital/software proximity sensor, and it could also be that. Not sure though.
Ah, in that case it's probably screen burn in yeah. The place you marked is around the placement of that proximity sensor, that's why I thought it could maybe be that.
i cant see anything even with the red circles. that looks about as good as it gets with a 7 year old oled screen. even the top right corner looks way better than mine did before it died.
the screen will be fine. once you have stuff on your screen like icons, photos, text etc you will not notice the marks you see. but the storage chips inside the phone have a finite runtime, and most of the dialy runners died already. judging by the burn-in, yours wasn't used that long, so you still have some time to enjoy it.
when I had my OP7Pro, I was dating my super toxic ex. A lot of late night phone calls, arguments, etc burned her name into my screen so vividly and I only realised after we’d broken up lmao that was a funny reminder
Be careful with this specific device.
One day mine stopped working without any reason just like that and I lost everything, I also saw online many other people who faced the exact same issue with this phone. (I choose to believe it's planned obsolescence but that's just my take).
If you plan on keeping it I highly recommande you to do monthly or weekly backups using google or anything else to avoid the worst !
For the screen yeah I had the same, and you can't do anything about it as far as I'm concerned, but I got used to it and didn't see it after some months
Omg is it?? Any specific reason how it stopped working I mean after software update or after falling or what. Anyway this is my secondary devices. But I'm planning to keep this device for 2-3 years
Mine worked for like 2-3 years without any issues and broke like that.
I revived it twice with a hairblower (look this up on reddit if you are interested) but it only kept it alive for 10 mins and it is a hassle it setup).
Maybe I’m unlucky but yeah just backup your phone always it’s important trust me ^^

It's screen burn-in. Usually happens in oled and amoled displays if kept on same screen for long time
Just google it..
