I was finally able to change the APN in the settings. It seems that it has to be tried more than once until it sticks.

Otherwise the double SIM works well (I tried with two SIM that I didn't need to fiddle with the APN settings) under OTA-17. I didn't try MMS though, I've never sent or received a MMS in 20+ years of using cell phones.

@pascal Hey Pascal.

I recommend you to open the bootloader manually. Works best on a Linux system. If you opened the bootloader, the installation of UT with the UT Installer should work.

fastboot flashing unlock

is the command you should use. Keep in mind that the phone must be set into the fastboot mode to execute this. If the VollaOS is installed you have to close the bootloader with

fastboot flashing lock

This had helped me to switch from UT to VollaOS

@mardy Same here, I don't know when it will be solved for RN7.
Also noticed that online charging works, but no charge indicator on the display....

@arubislander Hey @arubislander no problemo. If you could point out where or what i need to look out for in the log files, i' m good to go. I can then post the part that's needed.
Thanks for all the help!

@jimpson Can be but i only use Telegram so i can not tell you more mebay someone else can...

@marco said in No MMS on Vollaphone with Free Mobile ?:

for the sim yes it is super recent,

Okay. At least that's a start.. Something probably changed. I'll try to find an open store (because Covid) and ask around. Thank you.

Is it possible this is not a device bug but rather an OS quirk? If you are in an app using audio and press the volume buttons they control the volume for that app type. If you press the volume keys while nothing is running it adjusts the ring volume (at least it seems to on my oneplus one). Now for the real quirk, the buttons still adjust the volume while the phone is asleep. To test this turn the volume all the way down, press the power button to put it to sleep then press the volume up ten times followed by the power button. You will see the on-screen volume level and it will be up. If it is not on-screen press the volume button one more time to bring it up and see if the volume was adjusted while the phone was asleep. So it may be the volume is being turned down by the buttons while in your pocket.

@jojumaxx Did your try cleaning like i suggested you?

@domubpkm Ok, i'll do that next time i update my music. Thank you very much for the tip!

@moem Aha! Thank you very much. I'll go and have a look. 😁

@captaincook
Well if it's an obvious major issue like wifi doesn't work, or camera or calling it's probably device specific.
If it's a general question like how do I do this or that, or if after an OTA a feature is missing (regression) then it's more device agnostic hence better asked in support.

I know it can be confusing but support was crowded with device specific questions making it harder to find answers.
Now you can search the dedicated subforum and learn about what is not working yet and witness progress.
While you can ask for help about how to do something with UT ; how to sync my files with Nextcloud...
I hope it helps.

@dobey same here. I've just updated the app and everything's back to normal.
Thank you very much for the work!

@lakotaubp Quick and perfect ^^

@lakotaubp Danke 🙂

@domubpkm Yes, you are right. On Aquaris I used the File Manager to find the contact.db.
And I'm an 'idiot' 😁
I forgot to set visible all file in the Volla Phone Directory. Now I see it
Thanks again

@lsrb It would be after an OTA that you will lose your modifications. An over the air update works by downloading an entire read only image and replacing the current one. All of your user directories are safe but not the root file system below home/phablet.
