I can also confirm, that version 3.2.2 fixed the issue. (Volla, OTA-15 stable). Thanks for the quick solution!

@ubtouch-newbie I also use the vollaphone with OTA-15 and congstar (D1/Telekom). My sim is ~5 years old. When I stated with the vollaphone I had to type in the APN-settings manually. Since I did that, it works fine and I can use LTE.

Yes, the "L" in the indicator bar stands for LTE.

I also had this issue a couple of times. But I think I also had it before OTA-15. But I also can`t reproduce it consistently. When I got into the state, that the phone does not recognice a call anymore, it stays in this state. That means further calls are also not recogniced until a reboot.

I also noticed, that rebooting takes longer if the phone is in that state. The part that takes longer is the time it takes until the phone shuts down. After choosing "reboot" from the popup there remains a shadow of this pop-up for about 15s until it shuts down. Maybe some kind of process that got stuck?

@stanwood / @domubpkm after a minor fight with the installer (didn't boot automatically in recovery mode) I could manage to install the actual image with OTA-15. Channels are now visible as expected, and the check for updates works now within a few seconds.

Thanks for your great support & Wish you all a happy new year!

@domubpkm without wipe means that my contacts, pictures etc. will remain after flashing?

@stanwood yes I did. The actual situation is:

When I open the update settings it says:

By the way: I never changed these settings to "release candidate". They were already like that when my Vollaphone was delivered.

When I try to change the Channel ist says:

The fetching-process takes about 10min. (Which is much more compared to my former BQ E5). Maybe there is some kind of timeout after 10 min, but thats only a guess. After that I get:

There is no Channel at all to chose.

When I get back it says:

I have the same issue as described a few posts earlier by @st0rk. Are there any news about the update of Vollaphones to OTA-15?
