I've been in contact with the support directly for the camera issues.
A solution that works for me is the soft reset / whip cache: Hold the power button + volume up bottom until the phone reboots. hold until it goes into a second reboot and then let go. This way it clear the cache.
I'm guessing it's a ram management + some app that cause this issue. So not only HMD/Nokia is to blame for this.
@munnasharma @user1539331594868I will follow your suggestions. Will revert back if it works. Thank you
