there are many threads on the issue on reddit and here. none of their suggested fixes worked. actually the only thing that seems to help is opening up the device and reconnecting or replacing the camera.
basically what happened is the app crashed one day when i tried to go from normal to wide camera. after clearing cache and data and restarting it works again. but you can't get the wide angle to work and the selfie cam causes the same crash.
i have not tried a factory reset. i have had androids for maybe eight years and never found a meaningful way to back up info. whenever i get a new phone i feel like i am mostly starting over at least with half of the apps. i use mac computers and back up my phone to my gmail account. so i think at best its only backing up my contacts some apps and maybe the calendar.
with the headphone jack, i have noticed the problem with my apple earbuds, audio technica headphones and the cassette adapter i used to use in the car. that's a good simple suggestion i haven't tried though. so i will definitely blow some compressed air in there to see if it helps. but i think the device is just crapping out. i expect planned obsolence with phones but not after a year.
mine also has some screen retention but that doesn't bother me too much.
oh but back to the headphone jack
@Greedog said the V40 won't have one. is this true?
are there no other great flagship phones? i tried a samsung for a week when i first went android and it felt cheap. does anyone like google motorola HTC anything else??
THANK YOU!!!!!!
