Bug Reports
1

REPRODUCIBILITY: 100%
OS VERSION: 5.0.0.55, 5.0.0.61
HARDWARE: Sony Xperia 10 III
UI LANGUAGE: Finnish (not relevant)
REGRESSION: Yes, before Sailfish 5.0.0.55 no issue at all

DESCRIPTION:

After updating to Sailfish 5.0.0.55 I started to receive complaints about my audio lagging behind the video in Telegram video calls. The issue doesn’t seem to happen immediately after starting the video call but after a few seconds or minute. The issue reproduces at least when using speaker in video call.

In addition, I cannot reproduce this issue on WhatsApp video calls so seems to be limited to Telegram only.

PRECONDITIONS:

Android App Support installed and running. Android Telegram installed.

STEPS TO REPRODUCE:

  1. Open Telegram
  2. Start or receive video call
  3. Put on the speaker from video call settings
  4. After some time the audio should start lagging behind the video

EXPECTED RESULT:

The audio and video should remain somewhat in sync throughout the video call.

ACTUAL RESULT:

The audio starts lagging behind the video after some time, and the issue doesn’t resolve by itself.

MODIFICATIONS:

None

ADDITIONAL INFORMATION:

No relevant data yet. Gathering relevant logs etc. can be proposed with instructions.

It seems that I just now also experience that on C2 5.0.0.61.

Did you test if same issue happens with ‘‘Telegram X’’?

Also: Does this issue happens both when using wifi AND with mobile data?

4

I don’t use Telegram X nor am I planning to so can’t really say abou that. This reproduces at least with mobile data. I haven’t tested Wifi.

I can confirm the issue is with both mobile data and on wifi. Doesn’t matter if I initiated call or received call.

Have you tried it? I don’t even have the option to call video on Telegram X.

I have done studies on:

Yottagram - No video call option
Telegram X - No video call option
Forkclient - Works really bad overall (Broken?)
Mercurygram - Video call available, but it doesn’t connect
Telegram official - Works, but lags horrible after 20 secs

Since I need to video family and such, I also did try Whisperfish. That app is of no use for me at all.

Whatsapp works, but the volume on Jolla C2 device is being reduced to 5% on speaker after 10 seconds. No go there either

Does this telegram video audio non sync bug also happens on phones with the latest AppSupport such as C2 and IV, V ?
Did anyone test that yet?

Yes, unfortunatelly. Fix is intended to come this month IIRC.
