Hi Lee, I played around a bit today, now using aosp lockscreen instead of HTC's and had no camera problems. I will have a look on it the next days, where I will take a lot if pics again and report.
Now after magisk and magiskmanager update even with aosp lockscreen I get freezing camera again when waking up with power button or double tap fingerprint sensor.
Now it is more interresting for us in Tokyo, what the Thyphoon will do, beginning in two hours...
