It happens on the Huawei U8860. I installed my favour streaming app 'XiiaLive', it worked great on my HTC which can be controlled via BT handsfree, but on the Huawei the default streaming app preinstalled will be started instead when I click on the handsfree, I've to start my preferred app manually to allow the handsfree to take control, but this is not permanent, even I installed an app to make change on defaults, the settings will not take place, any idea ??
