The updater need to clean (like this post say). And the update take a lot of time (nearly 2 hours) but it’s not a problem for me.
The bug #7180 with Gallery on MMS is fixed
Thanks dev for you work. 
I have now updated to T and it appears to be working well. Still has the location problem, though.
Perhaps this means the note on the xz2c page the “this upgrade build could not be tested as there were no device specific testers available” is no longer true. If you have some list of tests, let me know.
No battery symbol visible. Only Gigaset in orange and ‘powered by Android’ in the lower part of the sceen.

Phone lagging, slower response, also get warning: “com.mediatek.ims.ImsApp keeps stopping” when sending SMS. Usually messages do go and do I get them, but often SMS messages “failed to send”. After reboot they do go when resending. But soon the problem reoccures.
Hi stanwood! I’m not sure if I ever charged my GS290 powered off, but now when doing so, the phone just shows Gigaset -logo and Powered by Android-logo. And keeps then bright on the screen all the time!
[Edit after the 2nd v1.15 update]
With the the first 1.15 update (1.15-r-202340914330641-stable-star2lte) everything works except sending MMS => It seems the new APN parameters for my Provider “La Poste Mobile” (on the SFR network) didn’t work for MMS only (4G was OK).
But after the 2nd 1.15 update few days later (1.15-r-20230915330641-stable-star2lte) the issue was solved => I noticed a new APN parameter called “MMS La Poste Mobile”. It seems to complete the existing “4G La Poste Mobile” APN, even it can’t be selected.
At the beginning it didn’t work for MMS sending. I had to select another APN et reselect the “4G La Poste Mobile” to be able to send MMS again.

I tried the upgrade to 1.15 and am now stuck in a strange screen that says: “Bootloader” please connect to your computer and use fastboot to interface with the device.
what am I supposed to do with fastboot?
It will not reboot and keeps coming back to this screen
Steve
Thank you.
I confirmed it was working well on 1.14.
When the GS290 was off and it was plugged on the charger, there was first the current splash screen “Gigaset powered by Android” during 5 seconds, then the battery charging indicator (blue battery color) came up with the battery percentage and you could see the fill rate in the battery icon.
Hello all.
Just updated to 1.15, smooth and quick as always, and seems to work well at first sight.
But I realise that OTA OS upgrade from Q to R, expected for this very 1.15, is only for stable build 
(note: I still can’t understand why this dev/stable distinction … apart that stable is for phones sold by Murena … but so what ?)
When will the R OTA upgrade be available for dev builds ?

Manual clean install of /e/OS-T e-1.15-t-20230917331436-dev-bramble (incl. e-recovery)
The first impression is good.
On 2023-09-29 I ran the OTA update and /e/OS version 1.15-s-20230913330639 (Android 12) got installed.
Most things work flawless:
But the “Camera” app is making problems: The mode “Focus: Auto” does not work anymore. See details in Camera has focus problems after update to eOS v1.15

The device was and is Magisk-rooted (solely to pass SafetyNet (please refer to https://gitlab.e.foundation/e/backlog/-/issues/7124 , which - as usual - hasn’t been touched by the team so far …))
Used the appropriate sideloadable firmware flasher zip from Wishmasterflo (https://github.com/Wishmasterflo/Firmware_flasher) to get the firmware right and performed a “dirty” system upgrade (via sideload too):
Everything stayed in place and works as before!
So this was really a straight and easy upgrade …
PS
I forgot to mention that the upgraded system is still equipped with microG Services Core v0.2.27.223616 because of the problems reported with https://gitlab.e.foundation/e/backlog/-/issues/7064 (which - as usual - hasn’t been touched by the team so far …).
Maybe that the new v0.2.28.233013 behaves better with respect to this, but as long as the microG team itself still considers v0.2.27.223616 to be the stable version I will also still stick with it …
Using easy-installer gives you also a ‘stable’ build.
Difference between them is ‘rooted debugging’ on ‘dev’ as far as I know. On ‘stable’ they also try to pass SafetyNet which for some app’s is necessary.

Thanks @mihi.
Is there somewhere some documentation that explains in details what’s in and what’s not in dev builds compared to stable ones, and also implications on the update process, OTA updates, OS upgrades, … etc ?
Installing the rc went smoothly, two days later I installed 1.15-s-20230913330639-stable-FP3 and it took some nine hours to complete the installation process.
Since then it is running fine with an average duration of 5.5 days.
Thanks for the good work.
