My Samsung galaxy a40's front camera couldn't focus on things which weren't close for about 3-4 weeks. Then, yesterday, the camera started to focus very well, but it worked only for about 10 hours, because now it's broken again. What problem is it? Is there a solution for that?
It sound as magic, if the objetive is clear and you have not an special protector on it may work fine!!!
If you continue with problems and you have warranty, could be better to use the Oficial Technical Service for test and help you my friend
Try to install a second camera program to check if we have a soft or hardware problem as recomendation and after desinstall it, it will be only to check cappacity or camera system
Good luck and I wish you can use that good fronted camara as all our can use it
