Answer to "Rear-facing camera won't focus"SOLVED FOR REAL THIS TIME I THINK. See my explanation above about installing Camera FV-5 Pro. While I love the app, it did NOT solved the problem. I still recommend you get it. What has solved it so far is this: Go to settings/Apps/Google Play Services/Permissions. Turn off Body Sensors and Camera. ALSO, Go to Settings/Apps/Google Play services for instant Apps/Permissions. Turn off Camera. The first step did not repair but when doing both it does. Seems at some time or the other I have downloaded an app such as Google Fit or something that affected the camera focus mechanism. I’ll keep you posted. I would still get the Camera FV-5 Pro app. You’ll love it.
Answer to "Rear-facing camera won't focus"SOLVED. OK guys. After much trial and error I have found a fix for me. I downloaded camera fv-5 lite. Focused worked for a while. Went back to blurry photos. Downloaded fv-5 pro. Same problem. After much trial and error determine problem must be a continuous focusing problem. Chose continuous focus on camera fv-5 lite and camera FV pro. No problem sense. To choose continuous focus it is the circular arrow. Hope this works for you. Camera fv-5 pro is an excellent app especially if you are a photographer with a DSLR. Controls are very similar.
