    My oneplus 7 has started showing a weird problem. When i press the lock/unlock button to wake up the screen. The lock screen shows a very weird colour, a mix of whitish and purplish colour. However the screen is back to normal once i unlock the screen using the fingerprint scanner. This happens only when i wake up my phone and other times the screen is working perfect. Can someone help me with this issue? The issue is inconsistent and happens 1 out of 10 times or so. Will try to share the picture as soon as it repeats.

    I've noticed mine does this when my brightness is low and I wake the screen to use the fingerprint scanner. I believe it morphs the colors to adjust for the fingerprint sensor to properly read your print. once the scan is received and the device unlocks, I can see the colors quickly change back to normal before it transitions to my home screen. I wouldn't worry about it, seems like it's programmed in for the sensor to properly work.

    Makes sense. But this is something that started happening recently, probably after the last update. Because i have never seen it earlier before, whatever the lighting conditions be. I have been using this device dor the past one year and started seeing this only since last week.

    Could you please confirm when this started happening on your device?

    I have seen this happen on my device since I first started using it.
