My Samsung m31 is showing issues with camera focus as the right side top corner is getting blurred each time I click a pic having text,same issue is occurring with the Adobe PDF scanner app.Due to poor focus problem scanner app is clicking few blurred text.Along with that the hotspot tethering is also not working with the Samsung cord but with other USB cord(e.g-realme usb cord) it is working properly.I don't understand why such problems are occurring,I have got my phone on 13th of Jan 2021 through online service and these problems are occurring after I updated to android 11.Is it the buggy software problem or hardware problem I m not getting it.Assist me Samsung
