[will send crash log per DM!] Crash immediately when opening the app [4S, ios 8.4.1]

[riotimbuggggg]

Hello!
I want to use riot.im for my iPhone 4S on ios 8.4.1 but it crashes immediately when opening the app, so I can't make a report or something, my phone is jailbroken though! Maybe there is a possibility somehow?
I tried deleting and reinstalling the app, and of course turning the phone off and on, but these won't work.
I haven't used riot.im before.
How could this problem be fixed, or how could I send an (anonymized!) report so you have the ability to see what's going wrong maybe?
Best regards!

Hey there! I was able to create crashlogs, and will happily provide them if asked per DM by developers (for privacy reasons).

Hi @riotimbuggggg, you can PM at @Manu:matrix.org.

The problem comes from a 3rd party library, WebRTC framework which uses iOS9 symbols:

- Dyld Error Message:
  Symbol not found: _AVCaptureSessionInterruptionReasonKey
  Referenced from: /private/var/mobile/Containers/Bundle/Application/XXXXXX/Riot.app/Frameworks/WebRTC.framework/WebRTC (which was built for iOS 9.0)
  Expected in: /System/Library/Frameworks/AVFoundation.framework/AVFoundation
 in /private/var/mobile/Containers/Bundle/Application/XXXX/Riot.app/Frameworks/WebRTC.framework/WebRTC
  Dyld Version: 353.12

I have opened an issue there: AlexKMDev/WebRTC#48.
I am afraid it cannot be fixed easily. The fix will probably be to move the minimal version to iOS9 - which I am going to do for Riot.

The minimal OS version of the app has been upgraded to 9.0 to match WebRTC framework requirements.
