Made by Camera360 (image Below). You could download it from the samsung app store if you clicked on Add More Filters...

I bought s10+ recently and cant seem to find that filter anymore.

Would greatly appreciate it if somone can send link to that filter so i can download it please. Thanks.

[Samsung Galaxy Note 8 Questions and Answers] Max_Terrible:
If it's a filter that you bought from the Galaxy Store, it should be linked to your account and you should be able to go through your old purchase history to find it again. If it was a free to download filter, then I don't have any further advice.
[Samsung Galaxy Note 8 Questions and Answers] Chumbuck3t:
It was a free to download filter from samsung App store, made by Camera360 :(

After formatting data partition, I am unable to restore backed-up data directly as I get an error (255?). I have to always let the phone boot to the welcome setup screen before going back into TWRP to restore my backup.

Is there something I can do to avoid this lengthy step?
[Moto X4 Questions & Answers] gee one:
I found the same. It's almost as if twrp doesn't format correctly.

I typically use fastboot -w, flash, then boot into the ROM, then restore from backup.

All roms seem to have problems with Sprint. It's hit or miss, and LTE is basically broken.

I've found that older pixel devices have had this issue on some roms, and it has to do with missing files for Sprint.

Also, there's a crash to com.android.phone when I go to Carrier Settings.

Here's the forum posts that talk about a similar issue: https://github.com/maruos/maruos/issues/20

Crosshatch w/ Aquarios stops charging....?

I was curious if anyone has had this issue. My Pixel 3 XL with Aquarios stops charging at 61% both plugged in and wireless charging. When I notice it, the screen is always dimmed, I'm not sure if the screen timeout is directly causing or has anything to do with this. I have had this ROM and set up for several months and this is the first time it has done this. Any help would be appreciated - But I can always reflash - I was more concerned with letting the appropriate people know about this in case it has or does become an issue.

Thanks!

Depends on the distro you use per what needs to be installed.

Never seen that error before.

Take the time to look over what all is needed per your distro and make sure you have everything installed.

We have a Telegram chat for users trying to build and wanting help.

Hit one of the team members up on TG and ask them to add you.

one other thing i wanted to ask, the dock keeps sliding up like it does when you first get setup to let you know to swipe up on it, but it does it all the time on this build on my phone, is that a known thing or is there a setting to turn that off?

The apps installed per Google's gapps are listed here.

It's very slimmed down with just what is necessary for working gapps like playstore, dialer, backup, setup etc.. with a couple extra like wellbeing.

Per spyware if you're conspiracy theorist thinking Google's on the watch them use something to block the apps you're afraid of. Lol

[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] MikereDD:
Disable the apps and or use an app that will uninstall them. Most likely an app that needs root like titanium backup or such.

Just know this could cause issues, so you're on your own if you have problems.

Try freezing them first and test for issues before completely uninstalling.

[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] smartymcfly:
Google owns Android, and it is an official Google phone, it is going to be basically impossible to remove Google completely. You can remove all the apps by Google and it will still be a phone that is made by Google and runs Android. Think about all the stuff that is not user facing made specifically for the pixel phones. If Google wants to spy, they won't need to use something like an app to do so, it would be coded into the hardware that allows them to do so.

This happens from time to time, I've had some times when flashing my test builds and the vendor mismatch **** wigged out.

You could probably avoid this by flashing the latest vendor images to both slots.

Does this app have a limit for login's per device ('s) maybe. You could try using an app like TitaniumBackup or Migrate to backup the apps data and restore that apps data after flashing the monthly updates and finishing the setup.

[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] bggold:
Yes but flash aug vendor to both slots

One more thing flash magic after first boot
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] AndroidPr0:
So if I'm coming from stock I need to:

- Flash latest vendor, reboot twrp (to switch slots), flash latest vendor on opposite slot

- Wipe system, data, cache

- Flash rom, reboot twrp, flash rom on opposite slot

- Flash twrp installer

- Reboot and setup

- Flash magisk

Is that the correct procedure?

Thanks!
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] mgp53:
I too can not find the WIFI calling option. After an August release, (flash_all) I set it up before installing Aquarios Aug release. I saw bggold mention backup of the setup. . Do you mean a nandroid? I didn't think that worked properly. Sharing your method would be greatly appreciated.
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] jlokos:
If you are coming from Stock August update, no need to reflash vendor (unless it is not flashed to both slots). Do not wipe system***. Wife data and cache, flash rom flash twrp installer; reboot recovery and flash magisk, reboot system and you should be good to go.
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] Shaftamle:
Why do you not wipe system?

Is the "flash twrp installer" step necassary if twrp is permanent installed and not booted?

[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] AndroidPr0:
Got the rom up and running, thanks!

How come wifi calling isn't working? I enabled it on stock and went through the agreements. I have AT&T. Turning the switch on does nothing and I verified no calls can be placed over wifi.
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] mgp53:
Same problem here TMobile. Although I don't even have the choice in the menu.
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] twcobra:
Its a finicky beast. I have it working on AT&T Here is what I did.

On AquariOS in About phone. Emergency info. I filled out all the information.

Dirty flashed stock and did the wifi calling authorization and also made sure to fill out the emergency info.

Verified WiFi call on stock.

Dirty flashed back to AquariOS and WiFi calling was then working. I have not done a clean install since so I have not repeated the process. So I am not sure if there was some other factor that made it work.
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] MikereDD:
I'm on T-Mobile
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] mgp53:
I know it works. Had no issue with July release. Can't figure out what I did (or didn't) do when updating to August .

Btw, Thanks for all you and the developers do for our community.
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] AndroidPr0:
Thanks I'll try this in a few days when I have time to flash. Did it prompt you for anything when u turned it on in aquariOS or did it just turn the switch on?
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] twcobra:
The switch stayed on when I dirty flashed back to AquariOS. Also if you get it working. Make sure you know what your passcode is. AT&T makes you enter your passcode for voice mail while calling with WiFi calling.
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] AndroidPr0:
Ok I know my VM pin. Does it make you enter it for every single call made over wifi or just for the first one or just for VM calls?
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] jlokos:
Everything I have read on xda states not to wipe system on devices with A/B partitions; you need flash twrp installer each time you flash a rom because the rom overwrites the boot image.
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] Shaftamle:
So my only other question is, if you're on one ROM and want to switch to another do you have to go back to stock first?

Fire Hound 8.1
[Google Pixel 3 XL ROMs, Kernels, Recoveries, & Oth] bggold:
Yes you have to and dont wipe system. Yes you have to flash twrp after you flash the rom. The boot.img gets flashed to and over writes twrp. Always flash magisk after your first boot.
