What is Google Camera (AKA GCam)?

Google Camera is the camera app for the Google Nexus and Google Pixel phones. It is not designed or intended to be run on other phones.

What is HDR+?

HDR+ is Google's proprietary image processing routine. HDR+ employs image stacking to control exposure, and also to preserve details, reduce noise, increase sharpness, etc. It is an all-in-one package.

URNYX05 will crash after I take a picture, on my mi 10, while burial works.

Thanks for the quick work.
[Xiaomi Mi 10 Themes, Apps, and Mods] sirTAVARES:
the xml is for burial maybe that is the cause of the crash.

burial is based on urnyx so both have the same base
[Xiaomi Mi 10 Themes, Apps, and Mods] Ezito:
Can u post some samples? I can't find anything... :(

I want to know if the camera is worth it.
[Xiaomi Mi 10 Themes, Apps, and Mods] manfred.exz:

[Xiaomi Mi 10 Themes, Apps, and Mods] AlexxAnders:
Detail & sharpness is great with Burial and the config. Colour is desatured & more natural.

Pictures follow...

Pictures taken in automatic mode with no zoom at night...obviously;)

Later I zoomed in 300% on both pics.

Which one do you prefer?

First pic is stock.
[Xiaomi Mi 10 Themes, Apps, and Mods] AlexxAnders:
With 10x digital zoom.

First pic is stock.
[Xiaomi Mi 10 Themes, Apps, and Mods] AlexxAnders:
Here I go again with 4 more ;)

From left to right:

Stock - Stock night - Burial - Burial night.

Burial definitely messes up the colours.

Can I correct this issue in the xml config?

The lights are both truly red.

Interesting to see, that Stock night also messes up the reds on the upper half of the pic.

At the moment I easily prefer the stock cam of the Mi 10.

Burial needs to be colour corrected.

Shots been made steady on a Tripod.
[Xiaomi Mi 10 Themes, Apps, and Mods] AlexxAnders:
I tested a bit with Burial...

Go into settings and put "HDR+ Enhanced Frames" to 30 or 45.

Also change "Pixel AWB in HDR+ Enhanced" to "Pixel 3".

That will do some "magic" :p

[Xiaomi Mi 10 Themes, Apps, and Mods] typos1:
Burial 7.3.018 works on mine (still running Android 10) apart from the built in gallery function, I just use the MIUI gallery.
[Xiaomi Mi 10 Themes, Apps, and Mods] typos1:
Yeah, its way better than the stock camera, the only minor glitches I ve found are that the error correction in the wide angle lense doesnt really work with Gcam and you cant get into the gallery via Gcam, you have to open the gallery app separately. I ve not used the stock camera since installing Gcam (other than to compare photos from both apps).

because I do not live in the United States, and this phone does not accept other SIM cards except t-mobile (network blocking). the built-in unlocking application says that this phone cannot be unlocked, maybe a bad ESN, don’t know, I bought this phone on ebay ...
[Moto G7 Plus Questions & Answers] JohnSmith8786:
Run the IMEI to see if it's been black listed, if it's not you can contact the carrier explain your situation and see if they'll unlocked it. However if it was bought at a subsidized price and the contract hasn't been fulfilled your locked to that carrier...

I bought this Revvlry Plus on Ebay and it arrived with the network locked up and then I proceeded to do network unlocking by server through a contact of mine.

I'm in the same boat, but haven't looked into it yet cause I'm using TMobile.

You should try to flash an stock moto g7 plus rom (not Revvlry) and see if your new sim will work. You'll need to erase your modem storage if it's not already part of the flash procedure (backup everything just in case)

fastboot erase modemst1

fastboot erase modemst2

Report back if you try this.

I actually resolved the first challenge I had by getting some good assistance in this thread:

https://xdaforums.com/oneplus-6/help/oneplus-6-twrp-boot-img-return-qualcomm-t4047773

But after everything was working fine with the TWRP, then I realized that I needed to downgrade from Oneplus 6 stock ROM for Android 10 to a new custom ROM with Android 8...

So I wanted to format whatever was on the phone, in order to do a clean install of everything.

But unfortunately I messed up, as I thought I could do it the same way as I did with my old rooted Oneplus One... and I went into TWRP and checkmarked all I could to format all I could, including SD card etc.

I am used to Oneplus One, and here the TWRP would still stay on the phone, no matter how much I formatted, meaning that I always had a totally empty phone... as I am used to format everything and connect the empty phone to my PC and copy the custom ROM ZIP on to the phone and then boot into TWRP and install it, in order to have a new fresh installation...

But now the format on this Oneplus 6 also removed the TWRP, so I only have recovery mode now, but fastboot devices command does show the serial number, so I do have some kind of connection, but also I have an empty phone with nothing at all. :)

I tried to do a boot with TWRP and a push with a random ROM, but this doesn't work now:

*******************************

PS C:\adb> fastboot devices

195ce6aa fastboot

PS C:\adb> fastboot boot twrp-3.3.1-17-enchilada-Q-mauronofrio.img

Sending 'boot.img' (28376 KB) OKAY [ 0.612s]

Booting FAILED (remote: 'Failed to load/authenticate boot image: Load Error')

fastboot: error: Command failed

PS C:\adb> adb push lineage-15.1-20181011_085513-UNOFFICIAL-enchilada.zip /data/media/

* daemon not running; starting now at tcp:5037

* daemon started successfully

adb: error: failed to get feature set: no devices/emulators found

PS C:\adb> fastboot devices

195ce6aa fastboot

*******************************

It seems that I found a custom ROM which is Android 8 = lineage-15.1-20181011_085513-UNOFFICIAL-enchilada.zip - but maybe not the best out there...

The mauronofrios TWRP that I got in version Q 3.3.1-17 might not be useful anymore if I want to install a custom ROM being Android 8.

So again, I am a novice and a fool here, and I need some kind of help now to get TWRP and a Custom ROM up and running now. :)

Thanks in advance guys!
[OnePlus 6 Questions & Answers] Osukido:
Anyone who have a good advise here?
[OnePlus 6 Questions & Answers] Paratax:
Easiest thing to do in your situation would be to use the unbrick tool from this thread.

https://xdaforums.com/oneplus-6/how-to/op6-collection-unbrick-tools-t3914109

This will completely format the phone back to Android 8 if you choose that version of the tool, and only requires 1 click after you install the proper drivers on your computer. Then you can start from the beginning and unlock the bootloader, then install twrp, and finally flash the Android 8 custom rom you want.
[OnePlus 6 Questions & Answers] TexnoViking:
Hm, I am just curious, why Android 8? Lineageos 17.1 should come out in a few month, which probably means that they will end support for 15.1. Why not 16.0?

Also, do not wipe random partitions. Follow the instructions for your rom. For example, for lineageos 16 you only format data and system

Hi All,

Just wanted to check and see how is VoWifi (or wifi calling) working for you guys. I’m in Australia and has an Optus and Telstra sim in my mix 3. Phone is running the latest Xiaomi.eu rom.

I’ve search around google in general and found that to get VoWifi to work there is a need to swap the carrier profile on the Qualcomm chip which I’ve done. I have done did the *#*#VoWIFI*#*# code to disable carrier check. However I’m not able to get wifi calling working at all.

Thought I check in here and see if any of you have better luck and if there are any tricks that I’ve missed and needed to try.

Thanks

[Xiaomi Mi Mix 3 Questions & Answers] LePala:
Unfortunately it is not that easy with the Mix 3. I have a simcard with working VoWifi in a Redmi Note 8 but with the Mix 3 VoWifi with the same simcard is not working. So it does not relate to the provider only for whatever reason.
[Xiaomi Mi Mix 3 Questions & Answers] Crim Soukyuu:
Give this guide a try. Works fine for me on K-Classic (O2 Telefonica Germany) on the latest stable MIUI EU ROM. Just make sure to switch to "prefer WiFi" suboption after disabling carrier check and enabling VoWiFi. I also had to enable the profile twice on sub0 for some reason...

edit: seems that's the guide you followed even though you didn't explicitly mentioned it? You should test that your phone does not default to another profile as mentioned here
