r/OnePlus7Pro

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

Hi everyone, I’m currently using the base model OnePlus 7 Pro 6GB/128GB as my daily driver. OxygenOS 10.3.8 runs quite well, but the Android version is too outdated, and some apps have stopped supporting it. I’ve tried various ROMs but haven't yet found the best fit for my 6GB RAM model. I’d really appreciate any advice or help you could offer,thanks!
