I developed 'Can't open camera issues' on LineageOS 18.1. None of the apps could open the camera, tried restarting, app data clear, none of it helped. So I updated the os to latest 18.1 with a dirty flash, then to Lineage OS 19 with a dirty flash, the problem was still there. Then I did a clean flash and the problem is still there. Can anyone help? Also, miss the customization bits on os19.
EDIT - Another bug that I noticed is, I'm not getting Call notifications, the phone rings, but the call screen doesn't show up. I then need to wait for call to stop ringing, then open call log, and then redial.
Update to this - after installing the update, I was constantly facing forced restart issue. After booting, The phone would restart after 50-60 seconds. And that cycled continued. I clean flashed the rom once again and the issue was still there. but the error went away after half a day, on its own. So I continued using it ignoring the issue.
About camera not starting - The error did not resolve. after a few days, my front camera started, but not the back one. Whatsapp camera, when opened, used to stay stuck at the first frame that camera used to see. front camera worked perfectly. That led me to believing that there was no hardware issue.
After a few more days, the phone died after a day or two. I was in the office with no charger, the battery died on me (my bad) and the phone refused to turn on. tried 15 seconds long press, volume down+power button, both volume buttons+power button, but none of it worked. Although I did see a 'battery critically low' error once, I quickly put the phone on charging and tried to turn on the phone after 10-15 minutes, and no luck. tried overnight charging using original charger, and no luck.
Assuming that I had CrashDump error a few months ago and some mobile repair guys had worked on the motherboard, I thought it must be a hardware issue and gave the phone to the repair once again. They charged me 50$ saying that there was some sort of IC issue on the motherboard.
I feel like I may have panicked and have been scammed by the people at the repair shop. I should have tried unbrick tools first. But in my defense, the phone wasn't even connecting to the PC.
Have had a very bad experience with the phone in the last few weeks. During my crashdump error, the phone repair guy said that this error is very common for oneplus 6 devices. I'm planning on getting a new phone now, and not a oneplus device for sure. I had glorious 6 years of oneplus one and then oneplus 6 died early on me. Also, not a fan of the direction where oneplus is going right now.
