GrapheneOS version 2026092500 released

DeletedUser1191

Both devices that I've updated to this version have been unusable before a restart and are fine afterwards. One is completely following recommendations owner only, etc and suffered the same. Pixel's 9 and 10.

Everything is perfect on my Pixel Fold. The performance is great, and it seems like the battery life is even longer.

All good on 2 pixel 9a's.

6 years on multiple devices, GrapheneOS has NEVER let me down.

Big love to all at GOS

Pixel 9 no issues.

Me too on 8a.
Connecting to an Openwrt AP version 25.12.4 gives Saved / Check password and try again

Might be good info here for the devs

Thanks for the link bitestring

iyanmv Thanks for the tip – it’s sorted things out; the phone’s working properly again, and I’ve even been able to re-enable the accessibility services.
Let’s hope that restarting the device won’t cause the slowdown issues to reappear.

Facing some issues on Pixel 9 Pro. Occasionally, I can't use my power button to lock the phone and it randomly reboots afterwards.

marcelo Gotten worse, I can only use the powerbutton / lock the phone if holding the power button. Just shortly pressing doesn't work anymore + the phone reboots / crashes afterwards.

SplatterGames

marcelo that sounds like the power button is physically broken, in all honesty.

marcelo

SplatterGames it worked as it should before i updated

marcelo

marcelo although entering the pin, the phone asks for the pin after locking again and doesn't let me use biometrics to unlock.

Works fine on my Pixel 10 Pro XL, absolutely nothing to complain. App optimization process this time was much faster as usual.

I also experience a pretty bad performance regression after the update on Pixel 9a. Also, the behavior after every reboot is strange - the app optimization process starts running with only 8 apps.

Since the latest update l want to add to my prior post with screenshots.

After my initial findings after the latest update l did a flash on my Pixel 9 in case of any corruption during download and installation of the latest update.

All flash operations completed with succes.
Radio A flashed.
Bootloader A flashed.
Bootloader B flashed.
Kernel flashed.
Super images ALL flashed.
Bootloader relocked.
Auditor report done with Attestation monitoring.
Both reports OK.

My findings.

1:
WiFi on owner profile NOT working at all.
WiFi on secondary profile IS working ONLY 2.4 GHz.
Hotspot on owner profile NOT working at all.
Hotspot on secondary profile ONLY working at 2.4 GHz NOT 5 GHz
Prior to latest update WiFi and Hotspot functions worked at BOTH 2.4 GHz and 5 GHz

This is what l am seeing now,
Screenshots,

Up to now there were ONLY two available 'Preferred Frequency' sections, now there are three and the number of 'Preferred Frequency' sections is changing at random even without a reboot.

2:
Vanadium Browser default available DNS services is different from the owner profile and secondary profile.
Up to latest update NextDNS was never made available as a default DNS provider. DNS4EU was part of the default available DNS provider list but NextDNS is NOT made available in the secondary profile list now while DNS4EU is.

Have GOS updated the list to include NextDNS?
If so why is the secondary profile DNS list NOT the exact same as the owner profile DNS list?

3:
When loading any web page on Vanadium there is a delay between the website loading and Vanadium's site control icon loading, 'Top Left of Address Bar'
The website loads first with this site control icon then split second later site control icon loads. Its delayed in the loading. This wasn't the case prior to latest update.
If you compare the binance.com screenshot bottom left to the address bar top binance.com you will see this.

Same lag issue with 8a. Literally took like 5-8 seconds for the phone to start showing who's calling me and present the opportunity to answer..

I disabled Developer tools;
Cleared System UI cache;
Rebooted;

I think it's better. Not sure if it's as good as it was originally because apps still take forever to load, but at least I can see that it's loading something and responds to my inputs. I never had animations on (and originally disabled via Dev tools, now I disabled via accessibility settings)

I don't know if this is release related but I had a restart after using Pixel camera app (that of Google) and I tried to switch from rear camera to front camera. The phone got black and after a while restarted, after I saw info about kernel crashed and a possibility to share logs on GitHub.
I hadn't tine at that moment but if it would be useful I would be happy to help.

Maybe you'll get other advice bu t take the following into consideration:

backup everything in case the phone gets worse
this could be a hardware failure
you can attempt to sideload a full OTA .zip file. This process does not deliberately delete any data. It replaces all of the OS.

Instructions
https://grapheneos.org/usage#updates-sideloading

Settings > about phone > build number
Match that number to the end of the following URLs. It either ends in a zero or one.

If you have a 10 pro XL:

Security preview:

Lastly, back up everything you can think of then think of what you missed and backup that too.

It would be helpful to know if clearing SystemUI data is enough to resolve the UI stutter issues a small subset users are having or if it also requires clearing Launcher data.

GrapheneOS I'm experiencing it on my Pixel 8. I cleared Lawnchair and System UI cache (not data) and rebooted and it didn't help. I just tried clearing Lawnchair data as well and it hasn't been laggy for the first few minutes.

I was also seeing the "optimizing" notification on every reboot, but I haven't seen it pop up this time.

I’m on a Pixel 8. I’m having a problem with lag. I’ve tried lots of things, but I’m slowly starting to consider a complete reinstall, even though it’s such a lot of work. This is the first time in two years I’ve had this problem. I’m on the beta channel. I don’t know if it’s possible to switch to the stable version without losing any data. I’m using a single profile with G
Google Play services.
