Hi guys,

I've some simple questions...

I've installed GCam with the instructions on OP, and all is gone perfectly; now I would like to update Gcam with latest Arnova version:

1) I have to unistall previous version, Is it correct?

2) I cannot find which version is installed : where can I see for this? In GCam Settings-Informations there is Arnva8G2 only

Last

Do anyone tried last Arnva8G2 7.9 beta?
[Xiaomi Mi A1 Guides, News, & Discussion] taurnilf:
You can install multiple gcam apps. I had 1.6, v6 and 7Beta9 at the same time before. Now settled with 1.6 and v7Final.

To know the app version, try going to apps->your gcam->app info.
[Xiaomi Mi A1 Guides, News, & Discussion] bojan1974:
first scruber version gcam,second V6. for me detail and quality is a same,but much fastes scruber version,of corse 1.6 is beter .your opinion?

[Xiaomi Mi A1 Guides, News, & Discussion] taurelio:
For a phone camera the difference between the two are negligable. 1.6 is better because of the slow, very slow hdr procesding. For a stable and reliable version of gcam eith great quality scrubbers version is the logical choice. 1.6 only wins at nigt photo but not by far

Hi, can anyone point me to Arnova's 1.6 GCam version that you all are talking about? Is there any special configuration need for that version? Please reply. :o

You can find the apks:

Over there you can find not only Arnova GCam but Other porting too.
[Xiaomi Mi A1 Guides, News, & Discussion] loliciu:
I use 3 versions of Google camera, but the one that I use the most is Scrubber version. It's the most stable, fast and to be honest you don't need more than what this one has to offer. If you are a professional photographer, than I should assume that you have your own professional camera and you are not taking pictures with your phone. When you are with a group of friends, you care about how fast the picture is taken and as a result, this app should be your choice.

Arnova v1.6 I use only with the rear camera (both in good and low-light conditions) and only when I go in some beautiful places and want to take pictures of the landscape, tourist spots, architecture of the buildings etc. in which I would love to get some more detail.

Arnova v6 comes with the best picture quality when you are talking about front-facing camera (again both in good and low-light conditions). I use this actually much rarely because I am not that much of a selfie guy, but when I want to take a picture of myself that looks a lil bit professional this app is the go-to.

These are the settings that I find to be the best for me in terms of picture quality + capturing speed.

1. Scrubber:

- Back-camera photo resolution: 12Mpx 4:3 format

- Front-camera photo resolution: 5Mpx 4:3 format

- Config HDR+: Pixel 2

- HDR+ parameters: Super High

- Final jpg quality HDR+: 100%

-> Advanced: HDR+ Control switch to ON

-> Experimental: HDR+ RAW+JPEG swith to OFF (you could turn it ON but please be aware of the available space on your device)

-> Developer setting: I have the following switched ON (diet_burst, fastswitch, gcam_enabled, progress_overlay, enable_micro, enable_vesper, gouda.front, raisr).

2. Arnova v1.6:

- Config camera HDR+: Nexus 6 Auto

- Model: Nexus 6P

- HDR+ parameters: High

- Back-camera photo resolution: 12Mpx 4:3 format

- Front-camera photo resolution: 5Mpx 4:3 format

- Burst settings: ON

-> Advanced: HDR+ Control ON, HDR+ Front camera ON, Portrait mode ON, HDR+ jpg quality: 98%, HDR+ RAW+JPEG: OFF, Compress RAW: OFF, Use ZSL: OFF, Remove pinkish/redish: ON, Show dirty lens warning: ON

-> Developer setting: I have the following switched ON (use_photos, diet_burst, fastswitch, gcam_enabled, progress_overlay, enable_micro, enable_vesper, gouda.front, raisr).

3. Arnova v6:

- Back-camera photo resolution: 12Mpx 4:3 format

- Front-camera photo resolution: 5Mpx 4:3 format

- Lens blur resolution: 12Mpx

-> Advanced: Auto-exposure mode: Auto, Config camera HDR+: Auto, HDR+ parameters: High, Improved Sharpness: ON, Disable front HDR+: OFF, Burst settings: Both ON, HDR+ image quality: 98%, HDR+ RAW+JPEG: OFF, Compress RAW: OFF, Improve in low light: ON

-> Developer setting: I have the following switched ON (use_photos, diet_burst, fastswitch, gcam_enabled, progress_overlay, enable_micro, enable_vesper, gouda.front, raisr).

EDIT: I should point out that going above those settings in v1.6 or v6 it will as a result take more time to capture what you want, while the actual quality might not improve drastically.
[Xiaomi Mi A1 Guides, News, & Discussion] gabricco:

[Xiaomi Mi A1 Guides, News, & Discussion] 5amar31:
They look identical. I can't see any difference between the two. Can you do the same for front camera? I'm currently using V6 for everything.
[Xiaomi Mi A1 Guides, News, & Discussion] bojan1974:
put arnova v6 auto exposure on slow,better details
[Xiaomi Mi A1 Guides, News, & Discussion] loliciu:
I know the details are better, but for a selfie the processing time is too slow, that's why I opt for auto; in this way it will use slow shutter only when needed (mostly in low-light).
[Xiaomi Mi A1 Guides, News, & Discussion] bojan1974:

No luck in installation

I have tried both manual and automatic methods, none worked.

For automatic : nothing happens on the screen after following all the steps multiple times

For manual : adb devices - nothing shows

adb reboot bootloader - error :no devices/emulators found

I have tried windows 8 and 10, 32bits and 64bits alike?

Any help?

Please provide screenshots of the device manager, adb and fastboot sessions.
[Xiaomi Mi A1 Guides, News, & Discussion] HitbP:
When I used the automated tool for the first time, I got stuck in TWRP, so I clicked "Keep Read Only" as advised. Still nothing happened, so I rebooted. The method didn't work tho, the "Manual Camera Compatibility Test" confirmed that nothing is activated.

After that, I also tried the manual approach, using those lines one after another:

fastboot oem unlock
fastboot boot recovery-3.2.1-1.img
adb devices
adb shell
setprop persist.camera.HAL3.enabled 1
setprop persist.camera.eis.enable 1
exit
adb reboot bootloader
fastboot oem lock
fastboot reboot

There were no error messages, so I assume there were no major mistakes. But still there's no camera2 api/... activated on my phone.

I tried the automated tool several more times after that. It finished without any problems (except I had to reboot from TWRP manually every time). But still, no success.

Any ideas what could have gone wrong? I'm using the global version of the Mi A1, language set to german, if thats of any importance.
[Xiaomi Mi A1 Guides, News, & Discussion] taurnilf:
What do you get when running "fastboot devices"?
[Xiaomi Mi A1 Guides, News, & Discussion] HitbP:
Me? Do I need to have the phone in fastboot mode for that? If not, I get nothing. If yes, I get a serial number 73eed.... in the first column and "fastboot" in the second column.
[Xiaomi Mi A1 Guides, News, & Discussion] taurnilf:
What do you mean by rebooting from twrp everytime. Did you have twrp installed?

My suggestion is to have your phone restored to stock then run the tool ir better yet, do the manual steps.
[Xiaomi Mi A1 Guides, News, & Discussion] HitbP:
I mean that I'm always stuck in twrp when the automated tool says "locking bootloader". For it to continue I have to navigate to -> Restart -> Fastboot.
[Xiaomi Mi A1 Guides, News, & Discussion] AndroGeek911:
i think the default apk that comes with tool is better in performance only issue i felt is zoom in potrait mode and slow motion videos are not working the other version fix these issue but pictures have more noise than the one that comes with the tool. and in very low light the focus is not good so low light pics turn out little bit blur any fix to that?
[Xiaomi Mi A1 Guides, News, & Discussion] taurnilf:
Okay. Do the manual steps. Use the twrp.img that came with the tool instead of recovery-3.2.1-1.img. Make sure "adb devices" and "fastboot devices" return something. Good luck.

It means that if you already have used this tool and are using gcam apps, you're fine to do updates. If you use or try to use this tool AFTER installing May update, data is wiped in the bootloader unlocking process.
