Camera focus issues with 2016-devices on custom roms

Hi there
Looks like i am not the only one, that having issues with the camera focus or autofocus on a newer G4 (H815) with custom roms.
It is definitely not a hardware issue, comes with ALL custom roms so far. it does not relates to stock roms (works fine there - tested many times)
marshell has written down a few posts to this issue. check his profile.
Any dev here, who can help?
Or is there any solution on its way?
Cheers, samukinson

My h815's autofocus is running perfectly with Imperium rom

Yeah, i know., but Imperium rom is based on stock. Genisys too.
This bug only applies aosp, cm13, ..., and apparently on newer G4's (2016)

Hi There, did you personally tested the stock roms without focus issues? Please list a few names I want to test because I am having focus issues with back camera. (I still have lollypop)
Thanks in advance

Genisys ROM: AF works
Imperium ROM: AF works
LG Stock ROM: AF works

Hello Guys, I had serious problems to get the back camera to focus when used on landscape mode. I moved back to stock ROM and didn't fix it, this was bad since day one I get the phone. How did I solve the problem? Replace camera module, now works great...!

Hi there? I've been having this problem too, stock or custom ROMS, where did you get the camera module from? Can you please share the details (prices, model number, seller, etc) if you can?
Thanks

Hello! Actually I did fit it in my local eBay (I live in South America) there are tons of LG G4 who have failed because of the motherboard so finding a replace should be easy but....This phone will continue to give you trouble, try to change it. I was able to receive a refund from Amazon for the whole phone. Good luck!

Mi5s autofocus problem

Hi all
Got new mi5s 4gb vrsion, autofocus do not work when camera start for 10sec-1min , after that all ok
https://www.youtube.com/watch?v=jAZhf2_zmSg
Same thing on oem and eu rom ,as well as few camera apps.
Any help appreciated

Please try autofocus not on a TV, they tend to be hard to focus on. Try it outside in daylight please.

Same thing m8
First time autofocus does not wok for 1 minute, than after than when you start it, does not work for 10-15 seconds.. Works normal for close up objects right on, but for far, no.

Same thing here... Could that be a driver issue?

This issue is known in at least one custom rom. Please make sure that you run an official rom. I believe the xiaomi.eu (not official rom) is also ok.

I'm running latest dev ROM from xiaomi.eu.
I also have the same issue on lastest official China global and China dev

That's not good then Not sure if it's a hardware issue in your case. Haven't read of this issue in the English xiaomi.com forum, so there can't be many with this issue.

I have same problem (4/32GB version). My mi5s arrived today and I couldn`t believe. Now I have two questions in my head "Is that software or hardware" and "Is it possible to be fixed"

I found a workaround (IDK if this works only for me)... Just open stock camera then open and close camera settings (gear icon). The autofocus should work now!
Let me know if this works for anyone else

I have the same issue when I try to take a photo or record a video . We are a lot of people with the same error. You can check the MI5S official forum at MIUI Forum and you'll see more threads talking about the same but there's no anwser from Xiaomi yet.

I'm also looking for a fix... Maybe only a patch for stock camera app until the problem is solved by xiaomi. I'll keep you updated

When I look to /etc/camera directory I can see 3 configs files for imx378 and two specifics for two manufacturers : liteon & semco (samsung). My sensor seem to be a liteon. Could the bug be link to a specific manifacturer ? Maybe a drivers to optimize for a specific manufacturer ?

Some people say that the last EU ROM, 6.12.22, improves the autofocus. Can anyone confirm it?

For me it's the same as on 6.12.8, BUT I tried the unofficial cyanogenmod for MI5S which seems it hasn't any issues in camera autofocus

I have the same problem.
But shaking, or knocking don`t help.
Even if i wait 15-30-60 sec, autofocus don`t work.
But first 2 weeks it works perfectly.

Can you confirm that flashing cyanogenmod really helped and camera work correctly now?

Camera stops - Nougat.

As I am experiencing problem with my camera on my LG I have to star this tread.
Maybe someone can help me solve my problem.
So last week I have installed the new ROM H-ROM V30 - I was coming from Freedom Rom 7.5.
So my problems with camera started. It is always crashing after launch.
I tried to go back to Freedom and it still no change.
Now someone in the Freedom 7.5 thread advised to go back to stock Nougat - camera bloobs etc.
So I did a clean install and it worked...
For like sometime.
I was thinking I will try again maybe the optional update did it from [ROM][H815] H-ROM G4 NOUGAT [v29a].
So I did only clean 1.0 and app is crushing.
I beg you help me.

I am like 99% sure now that this is a hardware failure. I have flash clean Nougat v29a - the 2GB file.
And nothing yesterday. Then in the morning the camera worked again. Now it doesn't work again.
I will replace the cam and see. Or maybe check maybe the connection is loose

I do not know what was it, but after flashing the 2GB clean V29a the camera is working fine. So it was fault of software.
Still, now I am afraid of flashing any type of custom ROMS - G4 without a camera i useless for me

Have you asked in the ROM thread? Happens with all camera apps?

I tried another app and the front camera works, but not the back one. Though with the default app I couldn't even test the front one, it closed immediately.
I know for a fact the camera worked fine before flashing the custom ROM, so it's not a hw failure.

When as the last time you checked the camera with a stock ROM? I searched around and there don't seem to be many people with this issue on the note 2. Your phone's model # is gt-n7100?

Yup, GT-N7100.
Last time I checked the camera was just a few days ago. And yeah I've searched for the issue a bit as well, didn't have an luck unfortunately...

Have you tried this ROM? --> https://forum.xda-developers.com/ga...-aicp-12-1-official-nightlies-t3569395/page85
I being using it as a daily driver for months, and it's the best one I ever had for this phone.
Few times I've had camera problems, but automagically resolved just after restarting the phone.
Give it a try, and let us know it this was an acceptable solution.
Best of luck.

Lineage 14.1 camera can't connect 8.4 WiFi

I rooted and flashed my tab pro 8.4 Sm-t20 with linageos 14.1 unofficial. So far everything is running fine but I can't get the back camera to work. I tried a few camera APps and a reset app I found on YouTube but can't get it to work. Has any one else been able to get it to work?
Thanks in advance

If you really have a need for the camera to work AFAIK your best solution is to downgrade to a previous ROM version.

I'd really like it to work it bothers me a little bit that I just can't get it to work. I really don't need it to work. I have my phone and another tablet that the camera does work on, have not rooted or put a custom rom on those. I do use Google duo and another app for video chat but it is what it is.
The thing is it's a shame Samsung isn't updating this model any more. It's actually got a slightly better screen and CPU than the 8" tab A I have yet it's stuck on kitty Kat with OEM software. I like having more updated software and the stock Android is more like what's on my Moto X4, so I'm not likely to flash it back to kitty Kat.
