DNS over TLS/IPv6 issues- Apps don't load data over Wifi

I can tell you I heard from them

You mean the fix that probably was implemented with QPR3 for Pixels, so after approx 9 months of first report in the issue tracker?

It’s also worth mentioning that the Pixel March update is different from the March (Android Security Bulletin) update that other phones get. The March update rolled out QPR3, the third quarterly update of Android 16, which updates many parts of the OS, not just security fixes. So, it has fixes that other phones do not have or get (other OEMs can release major and QPR2 updates).

The thread mentions first a potential culprit in the code at Google Issue Tracker and later a proposed fix at Google Issue Tracker I do not know what and when Google puts u into their patch releases.

But maybe let’s get this discussion back on track. There is no need to throw blame around and I do not understand why the the Google issue is mostly seeing voicy comments from FP6 users as of late.

Glad to hear you heard back from Fairphone. Currently the only thing I would suspect we can do is wait.

For sure it has to be mentioned that there might be other players involved when people are questioning FP isnt doing anything and it has no prio because its not fixed after 2-3 month. Its still marked as assigned in the Google Issue Tracker thus I guess its not officially solved? It was first reported in July 25 and there are still reports of Motorola devices from March 26.

So yes all we can do is wait, find a workaround that is OK for eachone and if not, sell the FP and move on to another device.

And also yes back on track would be great, so no general venting/ranting would be appreciated, only new ideas that help to mitigate the actual issue would be great.

I have read this thread on the Google issue tracker and compared my own environment, I don’t think it is the same issue. It might somehow be related, but I did a packet capture and I saw no RA with lifetime 0 in my environment and I still saw loss of IPv6 connectivity on my fair phone.

It seems to be somehow related to IPv6, but I don’t think it is the same issue, and should be raised and tracked as a different issue.

Same for me, could not reproduce this exact issue, no RA lifetime 0 visible.

Not mentioned in the latest update notes and obviously not fixed (just lost IPv6). :unamused_face:

Why was this issue not fixed in today’s update?

Because they are still working on testing potential patches

Damn, I’m really really annoyed that this still isn’t fixed. It takes so much from you to still recommend this phone.

Hello, I have this issue too. Sometimes I need to turn off Wifi so that the app I am looking at starts working. Especially annoying with videos. It also used to happen with my FP3 but I have no issues at all with my laptop… I always thought it is just normal smartphone experience, turns out it’s limited to Fairphones. Sad.

Is there anything I can help with to make the fix easier for the company? Any data or logs they need?

Hello, I’m new to Fairphone. I just received my FP6 few days ago. after startup and system update, I have the same issue. It’s pleasant to use but half of the apps that require an internet connection don’t start or take a very very long time. youtube is OK but googleearth not. the installation of an hotmail address in thunderbird took me at least 30mn (with endless servers verification duration), and now the access to the emails is rejected half of the time due to verification errors. a DNS modification changes nothing for me. turning WIFI OFF/ON works for a while. the same with airplane mode ON/OFF. another thing is working very well… : it’s removing the SIM card from the phone, you can’t call but all is working fine.

fortunately I can still use my old phone. As I can see in other posts I don’t know what to do regarding the delay and the lack of communication instead of “it’s in progress”. I still have a week to cancel the sale without justification and send back the phone to the shop, or finger crossed I put the phone on a shelf for weeks waiting for a potential fix?

It’s not, this issue is also present on (some?) other phones with Android 16. As I mentioned upthread, my Pixel with GrapheneOS has the same issue (well, not anymore since I swapped out our Fritz!Box) and in the Google issue there are also some people with Motorola phones with the same issue.

Welcome to the forum :slight_smile:

Interesting. If others who are seeing this problem want to make the test, it’s probably enough to disable the SIM without taking it out.

Settings > Network and Internet > SIMs
and disable the toggle.

EDIT - Don’t bother. I’ve just made the test. IPv6 is lost after about 10 - 15 minutes.

I haven’t physically removed the SIM though (I’m using a card in my FP6).
@jmf Can you indicate how long your IPv6 connection is lasting / lasted?

Useful website (already posted by nanoc) for checking your IPv6 connection: https://test-ipv6.com

EDIT 2 - After physically removing the SIM I still lose IPv6 after 10 minutes.

As has already been pointed out, all these temporary work-arounds come to the same thing, Whether it’s Aeroplane mode, turning Wi-Fi off and on, rebooting, … each time, you’re just restarting IPv6, and it fails after 10’ or so, from what I can see.

So far the seperate dns app (1.1.1.1 cloudflare) workaround has worked for me. No major issues so far. Sometimes a little buggy, could also be my internet, but less so than not having it.

Just install the app, connect, and it should work fine.

I just got a response from FP on my service ticket regarding this issue.

Dear customer,

As i already updated to FP6.QREL.16.69.0 and the problem still exists, i told them that this update didn’t fix the issue.

Anyone else got this reply?

Regards,

Peter

Thats just the standard response. For sure the latest update would not have fixed this, thats clear to everyone in development

EDIT - Don’t bother. I’ve just made the test. IPv6 is lost after about 10 - 15 minutes.

I didn’t noticed that it was temporary but I didn’t measure the duration. Now there’s something new: as I don’t want the phone to lose the connection during a critical app use and as some apps send codes for double authentication by sms I decided to disable the wifi and o stay on 5G only. so It stayed in this state during 2 days and surprise this morning the wifi was turned ON again automatically, and all the apps are now working properly without any delay like before. I don’t understand because I didn’t changed anything since yesterday. can any update be done during the night without permission.

I just checked the FairPhone Public issue tracker for the FP6, and this issue appears to not be listed as a known issue. For example, I see no references to IPv6 or RA packets at all. There is no reference to the Google issue tracker either. The “apps are slow to load” issue with the clear-cache workaround for Webview appears to be unrelated.

The page says it was last updated in March, so I hope it’s in their internal issue tracker.

That can be controlled by the user. It’s possible to have Wi-Fi turn on automatically when the phone is within range of quality known networks.

It is also possible to have mobile data remain available to apps even if Wi-Fi is active. This allows more fluid hand-over when passing from one access point to another, and of course when the required Internet resource is not obtainable over Wi-Fi, so I’m not that surprised.

Be aware that using mobile data may have an impact on your monthly mobile service account, but if that’s not a problem then keeping mobile data on seems to be your best option until the patch arrives to correct this problem.

Well I’ll add to these experiences: after reading all the posts I asked my provider (Delta, NL) to switch off IPv6. And I was cautiously content, the problem seemed solved. But no, after a day, day and a half it just resurfaced. It’s a shame, but I also understand that this is not a FP issue. Thanks for all the information.
