I have the same problem with my A5 2017 and i also hate the fact that their is no OIS in back camera.Samsung should atleast by a firmware update add EIS or some kind of software stablization and fix the front camera
This problem is very seroius #samsung please do something you have spoiled my vacation because of this issue....i cannot take good pictures of me because of this front cam focus issue. I bought new phone after my LG G2 (best mobile ever) and was highly disappointed with this front cam focus issue. Recall all your A5 2017 and fix the problem or upgrade the mobile for free. I will raise this issue in press also on UAE.
The problem with the camera comes from the Samsung camera app... Try to change the app with Retica, for example. If you do this you'll see that the front camera is awesome.
Since you are an engineer, so my qs is, "Is it possible to rectify this problem by updating the phone or using any other camera app? or it's something related with hardware issue which can't be solved." I bought a A7 2017 few days back and facing same problems now.
YES INDEED I AGREE, just a full stretch of my arm is enough for it to loose all the focus. I'm a photographer and having a fixed lens and yet having the focus range not set to infinity, I'd rather have a higher aperture to keep everything clear. And it really sucks when it comes to wefie, didn't wanted my friends to be bokeh.
