Couple of bugs I found so far:
-Zeam always installs (Comes as an system app, while the other launchers are apps you can unistall)
-Same for Nova launcher
-Voice search installs even when you don't select it
I instsall it on 2 phones now, both customized. I can confirm that Zeam launcher is always installed but I never get Nova launcher. I also don't get voice search.
On the phone which run on Semaphore 1.20s I find one Bug in Bluetoth today. With my free speach tool (HAMA Mirror) I can connect and also get calls fine but I can't call anybody. It dial and the one I called get the call but don't hear me. So incoming calls fine, outgoing calls don't work. without Bluetooth everything work fine.
On the slim Kernel phone I see that the Batterie loading bar you se when the phone is switched off don't work.
