Hello,
GCam mods:
This gcam 4.2 mod originates from Potter/HTC developers and has been tweaked for sharpen and higher frame count on our device. Also be sure to go to settings and set Potter Extra/af to 20x (will be set as default in future).

2x Exposure Mod
This magisk module is for Ali and pie vendor only.

For Pie Vendor Only and will make viewfinder laggy

This shutter speed will be twice as slow as what is displayed in exif or manual mode.

2x Exposure Mod work on the official ROM Ali?
there is an improvement compare to the apk gcam 4.2 of the LG Q7 that is used on moto G6 Oreo?
The exposure mod will probably only work on pie vendor.

The lg q7 gcam has lower max hdr+ frame count, no raw support, no manual focus option, broken auto focus, and high digital gain usage.

I think you will see better results with this mod.

1.0 is better than 2.0

Use version 1.0, in my opinion, it is better than version 2.0 for photos and I do not think a new version is coming.

Could you give more useful information please? How is it better?

The image quality of version 1.0 seems to be better and sharper than version 2.0, just as the file size is larger in 1.0. In version 2.0 there are bugs already mentioned in relation to RAW photos, the camera crashes if you take snapshots in fast sequences with the HDR + enabled and there is no way to take new photos until HDR + processing is finished. (In version 1.0 it is possible).

Okay, working on fixing them. I'll apply the old sharpen values and change buffer size to accommodate more hdr+ pictures. 1.0 had more sharpen artifacts however, which is partly where the increase in file size came from despite same jpeg compression level. In lower light settings you'll have slightly fewer you can process nonetheless due to higher possible frame count.

Just fixed infinite focus in 2.0 based by setting correct hyperfocal distance for G6, but will upload after a few more fixes.

Version 3 seems more stable, with no apparent bug, good and stable photo quality. The only problem is still the impossibility of taking a new photo until HDR + processing is finished, but otherwise, it's perfect. :)
I can do another variant or option for lower hdr+ frame counts to work around this, but it is a trade off. The high frame count causes this.

If you feel better, fine. I do not think I have much trouble waiting a little bit for a new photo. However, I do not know how other people do.
Yes, I'll do another variant with a lower frame count within about a day. You can also just disable hdr+ if you want to snap quick photos. Only regression from v2 to v3 is smartburst is enabled but doesn't work, in v2 it was disabled because of this.

Hey, a bug found in version 3: You can not make recordings on the camera. :(
Edit: only occasionally, the first attempt at recording did not start, but at the second attempt it seems to be already working

    In version 1, try taking multiple photos in sequence with HDR + enabled. Then in version 3, take several photos with the HDR + activated in sequence, you will see the difference.
    I understand and can recreate this, it's a symptom of setting higher frame count. Next release will have two variants -- one high frame count, and one stock frame count.

    I mean I can't recreate the camcorder issue.

    Hi, I'm testing GCam V3.0a1 and found two issues. First of all, the automatic HDR+ not work properly, it helps turning on flash or turning on HDR+. Secondly, the front camera produces noisy pictures at low light, as if noise reduction was not enabled. In GCam from LG Q7 in front camera he takes better pictures in low light. Nevertheless, it is the best GCam mod for G6. Thanks. :)
    The front camera issue is known and an issue with savitar's mod for front cam. The issue is actually that exposure is locked very low on it, so there's too much digital gain. I'm working on a fix, but for now you can use the iso slider on the left which will also change exposure. Front cam actually supports up to 1/2 sec exposure with manual iso slider, which produces very good low light pictures.

    Hello,

    what brings more than gcam 4.2 on oreo?
    this allows a better night photo?
    As long as we're 32bit, we can't get newer than 4.2.
    Yes, it does.
