For this reason, we have provided the template below for you to fill out with information about your issue. Please provide as much detail as possible so we can most efficiently resolve your problem.


Description of the issue:

How can this issue be reproduced?

  1. Have one new phone and one with open tabs and settings
  2. Scan the qr that’s shown on the old phone in the sync setting using the new phone
  3. Wait as long as you want and see nothing is synced.

Expected result:
Settings open tabs and everything that is checked will be synced to the new phone.
Brave Version( check About Brave):

Hello and thanks for this, here’s what I get:
(ERR_NAME_NOT_RESOLVED)
do you know the exact domain it is trying to reach? I looked at the logs but found nothing related to brave being blocked.

I managed to get it to resolve, but the synced changed are not applied on the new phone. The settings are not changed open tabs are not changed, even though it shows it downloaded the commits.

Any Idea how to get it to work?

Are you sure you changed the data preferences (settings → Sync → Data preferences) to include all that ?
Also, the open tabs are shown under history and not directly I guess.

Yep, made sure of it on both phones. Checked the history, but settings are not synced which is more annoying.

I have the sync dump right here:

Hey @Undertaker666. Let me try to go back to step 1 here and just kind of verify where you’re at in everything. It’s not that I’m doubting you have everything right, but it’s just that as I’ve helped various people here I’ve learned sometimes it’s good to take a step back and make sure we’re on the same page. Going with assumptions has been a swift kick in the nuts sometimes. lol.

If I can catch hold of the issue, I’ll get you to a solution. If I see it’s not going to be something simple, I’ll tag in support so they can figure out the complex issue. But hopefully it’s nothing like that.

I’m just going to ask that you be a bit patient with me and repeat information if necessary.

  1. What version of Brave do you have on both devices? I know earlier you mentioned latest but I try not to make assumptions. This could be “the latest” on Brave Nightly, Beta, or Release. It could also mean “the latest I could install on my phone, but it stopped being supported months ago.” So it does help if you can tell us exactly which version you’re using instead of just saying “the latest.”

  2. To be clear, you’re syncing between two Android devices, right? Which versions of Android are on both?

  3. If you go to SettingsSync and look at your device list, which will say DEVICES ON SYNC CHAIN, does it show both phones? It should show one that says (This device) and then list others besides that. For example, here’s a screenshot below from my Samsung Galaxy S9 below:

  1. On the bottom of the screenshot above, you’ll see there’s a button that says Data Preferences, it’s below Add New Device. If you click on Data Preferences on each device, do they have permissions turned on? Such as you see below in my screenshot, everything is toggled over (with the primary Sync everything standing out more).

Again, as simple as it is, sometimes people have left something untoggled here on one device but had it on in the other. If it’s not toggled on both, they won’t sync with each other. So it’s good to verify here.

I just want to make sure none of the above is going to be where your issue might be. Believe it or not, been a number of times people accidentally had devices on different sync chains, had been trying to sync devices that couldn’t be synced because they were too far outdated, they hadn’t enabled features to sync, etc. So that’s all I’m verifying with you.

SIDE NOTE
Other thing I’ll tackle really quick. What are your expectations on it syncing?

For example, open tabs won’t actually automatically open on different devices. When it says to sync open tabs it just means so the devices can see what’s open. On Android, you check this by going to the hamburger menu and you look at Recent Tabs.

Again, I know this terminology is different and some people had different expectations. So when you say it’s not synced to your phone, which place were you looking and what did you expect?

In terms of settings, I don’t even really know what they sync. I’m pretty sure they haven’t synced any major settings ever. Overall this is more of a misnomer if I remember correctly. The big things that get synced between just would be your passwords, typed history, and bookmarks.

yes.

already the same.

I know tabs should show up in history from other devices and everything you wrote, nothing is synced. no passwords, no bookmarks and nothing in the sync settings page.

@Undertaker666 Thanks. It just helped to make sure a lot of relevant info is there and it’s not sounding like it’s one of the basic steps people have had issues on. While I could randomly guess on things and ask for more details, I’d likely be wasting your time.

What I will let you know is that I’ve messaged @Mattches and @steeven while also tagging them here. I’m sure they’ll swing by with some suggestions and/or questions for you. But definitely wanted to try to get some movement on it since you’ve been holding out for assistance for 20+ days now.

The only other thing I might suggest, if you want to try it, is to leave the sync chain on both devices and create a brand new sync chain. Not sure if you’ve tried this before?

Great support from @Saoiray and @SmartyAadi here.

I’m honestly not sure why it’s not Syncing — everything seems to be setup correctly and if both devices are showing on both phones that means that they did Sync properly and are on the same chain.

I know it may seem basic but have you tried removing both devices from the chain and then starting over and syncing them together on a new one (basically just equivalent of turning it off and on again lol)?

If you try and that doesn’t work, can you please (while they’re Synced together) go to brave://sync-internals and take a screenshot of this page and share it here so we can take a look under the hood?

Yep, did that as well, did not apply the settings.

I posted the dump from that page earlier, does that not help?
Thanks for trying to help btw.

This is still not working sadly…

Tested again today, even got to uninstall and fresh install brave on the new phone.
Tried both scanning the old phone, and scanning the new one, did not make a difference.
On the new phone, sync-internals does not load at all now.

@steeven @Mattches wanted to loop you guys in again

@Undertaker666,
Apologies for losing your thread in the shuffle. I’ve asked additional team members for input here because I’m still not sure why this isn’t working for you.

Out of curiosity, are you able to Sync data on either of these devices to any other device you have? That is, does either phone Sync data with your laptop, for example?

Have not tried to sync a desktop.
I dug into what was synced on the new phone, I can see some passwords being synced, but nothing shows up in bookmarks or history.
Settings (which is the main concern for me) do not change at all.

Hey. I saw that you have a galaxy and pixel device. Not sure what exactly it could be but suggesting.
I have a Xiaomi device which runs MIUI, so for me, for sync to work, I need to also allow ‘Auto - sync’ data in my main phone settings app. Could that be something which needs to be done on the galaxy or pixel ?

Yeah, that is not something that’s relevant here. Thanks for trying.
