Hi. Distinctive Ring Tone that matches Incoming Caller ID is broken in this release - does not work at all. Had to revert to v198 to get functionality back. Pls fix. Thanks


Any update for a fix?


They work correctly, just checked.
Not sure what kind of “Match Incoming Caller ID” you used.


Are there any plans to upgrade the android version from 4.2.2 to 4.4? I saw that the phone is running on an Allwinner A20 cpu (according to cpu-z). The latest available SDK should support Android 4.4
multiple integration apps for the clients we support, have a minimal required SDK version of android 4.4…

The A20 is listed with support for 4.4
