Camera Focus Issue

Hi Guys,
As I'm sure you are aware there is an issue with the camera that affect some batches of Mi 4i phones.
This issue result in out of focus photos.
The phones work weel up to rom version 6.5.6.0 and from then onwards you get the issue, which means there was some in the rom development the conflicts with the phone hardware.
Xiaomi does not care less for for us as they are pure money driven, therefore I wonder if there are any devs willing to find a solution for this issue.
Meantime, me and many are stuck with firmwares up to June/2015.
With custom roms, or 3rd party firmwares, the camera works flawless, although the quality from photos and videos are miles away from the quality of a MIUI rom. This issue is only noticeable when using MIUI firmwares.
Hope someone can contribute for trying to solve this completly negleted and ignored situation by Xiaomi.
I can test if you need.
Thanks

Have you given a try to SnapDragon Camera?

Off course. I have tried everything within my limitations.
Something changed from firmware 6.5.6.0 onwards and it's within the firmware developing which means it affects any camera app.

Best umi z Rom ???

I dont know whats the best and newest stabel rom for the umi z. I found. Umi z lite, Noa MM and Nougat. Gemini. Or the Original ? Can anyone give a answer pls

I would love to know that too. I've seen a few ROM's that seem to be better than the Umi Z Stock Rom. However, with the 7.1.1 Lite ROM it's almost impossible to read the user experiences, because it's on a Russian platform, so I have to rely on the quality of Google Translate.
For me, I've experienced the following issues on the stock ROM (latest OTA of MM) ;
- sometimes the sound stops working (alarms, ringtone & music etc.) and I have to restart the device to make it work again.
- video's don't have the best quality
- the camera is barely usable on third party apps (Snapchat, Google Camera), because they cannot change the ISO values? (or so UMI says) Result: very dark video's / photo's
- the phone sometimes heats up to a point that I have to stop using it in order to let it cool down again. I don't know if this could be solved by software tho, maybe it's just a hardware problem...
- connectivity > in the supermarket / stores the connectivity is really bad. I have zero signal. With this, I also don't know if it's software/hardware.
- Bluetooth > Very short range before it starts to sound really bad
Did anyone have these problems too with the stock ROM and did the custom ROM worked for you to solve these problems? Also, what issues have occurred on the custom ROM? I would also like to know what ROM has the best battery performance.
I'm sorry for this long post, I just really want to find out, like Dobberman, what the best custom ROM is for this phone (cuz for me the stock ROM crashes / has a lot of problems)
Thanks in advance.

So I am as much as you. I've read all sorts of reports from users of all the roms out there. But I must confess that the best Rome is still the last floor nougat. On the nougat rom I then flash some tools like greenify and make build.prop settings. After that she runs real solid. The reception is not the best on the phone, but Build.prop tweaks can improve things a bit. So I actually received quite a good reception. In shops, he is not so great, but usually sufficient. Have now actually tested all available roms.

So you are now using the Umi stock Nougat ROM with tweaks? I've read a lot of problems about the Android 7.1.1 update on Umi Z (having to restart after flight mode etc).
Did you try any of the custom ROMS? What problems did occur to you when you tried them?
I've never done anything with build.prop settings, so I'm not quite sure if that would be an option for me..

I don´t have anything Problems whit the Stock Rom.
At the beginning I also had problems with the stock rom. But I could fix it by simply flashing all of Rome's releases with the flash tool via firmware upgrade without having to start the phone until I had installed them all after each other. (also the beta version) After that everything worked well for me. Only I do not get more than 4-5 hours of screen on time. No matter what I do, but that will simply be due to the processor ... you can not really adjust this. I tried everything.
The custom roms are just so that most have a very bad camera. The battery life is usually not much better than the normal Stock Rome. Otherwise, I have not been able to detect big bugs.
As long as we do not get source code, it will not change much, I think.
Edit: you can See my sot. I test whit amplifiy. Powernap ans other tools like xposedandroidtools. And also you can See the green signal all the time.

Based on what you said, I've decided to upgrade the ROM to Android 7.1.1. The performance / speed is a lot better on this ROM and thus far I have not experienced any lagg or apps that stopped working; which is a relieve. However, the quality of the camera seem to have dropped and there is a greenish tint on it. Also, on third party apps it is still too dark to make pictures / video's.
Are the mentioned tweaks the ones to fix these problems? Or did you install another camera? I've seen the Lenovo and HTC camera in other threads about the Umi Z. I hope you can help me

Great hehe. I can say thats not a camera APP Problem. You update the Software From the Start rom, whit the flash tool as Firmware upgrade. And you will See the Problem gone. I have this find out as i flashet the Rom back and forward many times and testet the Rom differents. From all original umi z Roms. DL all original umi z roms and flash it. Dont Start it. Finish The last flash and you can Start it.

I'm sorry, I tried to understand what you wrote, but I have no idea what you're saying xD (I have no experience with this stuff). Are you saying that you have to flash the ROM and test the camera every time? It sounds really weird to me, sorry

What do you mean with " install all the ROMS?" Isn't it true that I only have to install the latest ROM (V7.01.20170711). Are you telling me that if you flash this ROM (instead of OTA), that the greenish tint in the camera and the dark camera in third party apps will be gone? I honestly don't understand how that could be possible. I've had the same issue with the dark camera in all the previous OTA versions. Only the green tint occurred in the 7.1.1 ROM

download all official roms and flash all with the flash tool from umidigi with firmware upgrade. Begin with the first version of the umi z cellphone. Until you arrived at the last version. then you can start the mobile phone. No cam probs more

I did these changes to build.prop
ro.signal.4g=-140,-135,-130,-125,-120,-115,-110,-105,-100,-95,-85,-80,-75,-70
ro.signal.3g=-140,-135,-130,-125,-120,-115,-110,-105,-100,-95,-85,-80,-75,-70
ro.signal.2g=-140,-135,-130,-125,-120,-115,-110,-105,-100,-95,-85,-80,-75,-70
ro.com.android.mobiledata=yes
persist.radio.mobile.data=9,9
ro.mtk_world_phone_policy=1
resulted in a much better signal from mobile provider. 4G reception vastly improved. Thanks Marly97

Suggestions on ROM & camera app

Hey guys, new comer here.
So I've flashed lineage os 15.1 and it has been doing great, but the battery life is worse than that on latest global stable version of MIUI. Do you guys have any good suggestions? (Also tell me how to root Resurrection Remix if you're suggesting it, I tried but failed)
Also, all 3rd party camera apps (those I tried at least) can't take long exposure shots (longer than 4 seconds) and they're buggy to say the least. On that front, I missed MIUI since the stock camera can take shots up to 32sec shutter speed with ease. Do you guys have a fix for that?
Hope my questions got answered and happy modding guys.

Best camera [Custom ROM]?

Hi everyone. I recently flashed a new ROM on this device trying to escape from the overheating, I was expecting a proper camera app but I only found bugs.
I tried Pixel Cam V1.1, I used it on MIUI and it was great but on RROS it became unusable.
Gcam MGC 8.1 by BSG worked but it only recognizes one sensor of 8mpx.
Also the UltraCVM UltraCam but it has so many bugs with lights that is unusable.
The chosen one was Tiger Camera Xmas release, it's almost perfect but trying panorama mode makes it unusable, fortunately the 2x and more are stable.
But I ask for someone that probably have tried another apps or xml config files.
I am considering install the MIUI stock camera from ANX but the POCO X3 isn't listed as compatible device and I don't want to root my phone to be honest. But if someone know about one functional version I will apply it as last resource.
I'm opening this thread to know your opinion, I researched on Gcam thread but it has too many versions that I've tried. I really liked all the sensors and the 64mpx so I need to find an app that takes me closer to use the full camera experience.

FYI, there a whole thread dedicated to Cams at https://forum.xda-developers.com/t/4164397/.

Yeah thanks, I put the same above "I'm opening this thread to know your opinion, I researched on Gcam thread but it has too many versions that I've tried" everybody are talking about updates of the updates with different dates and versions

Solution for the camera

Since an update while ago the camera got from really good to bad.
I read on several places on the web where people experince the same thing.
I wounder if there are any solution to this? Any rom or mod for the stock firmware?

A factory reset doesn't fix it?
There's GCam, which may improve photo quality: https://forum.xda-developers.com/t/google-camera-mod-for-the-zenfone-6.3965028/
