I have got brand new the Samsung galaxy a71 and the front facing and back camera in all third party apps seems to be grainy and blurry and struggles to focus and almost struggles to catch up with anything moving say if I record a video. In those apps. This is really annoying as I use this phone mostly for Snapchat to take snaps. Ist especially worse in not great lighting but the issue is still present in good lighting.
Anymore details needed I'll be happy to comment I just need this sorted as it's starting to annoy me
