Bought the phone back in 2019, used the camera almost every day to login to whatsappweb for work and read QR codes. Two /three weeks ago started getting the blurry / out of focus problem. Now need to get a new phone as I can't log in to Whatsappweb anymore and cannot read QR Codes !!!
No new apps added to phone, I have tried every suggested fix I can find on the internet.
