after replacing SHA-1 cert with a new SHA-2 cert (server side), our cordova android app (ios still working) does not work anymore. Meaning that the https requests fail somehow (on all devices available to us - Android 4.3;4.4;5.1 - Cyanogenmod 4.4.4).
Strangely this only happens if the app is installed per apk. If installed per adb everything works perfect.
We check everything we could think of (e.g. chain, https://www.ssllabs.com/ssltest/analyze.html, etc.). Nothing indicates a problem.
Both certificates are form Comodo (PositiveSSL).
Every hint will be much appreciated!
ps.: we switched back to a new SHA-1 cert but this will only work for 30 days.
