I have recently replaced the stock samsung system on my note 2 with paranoidandroid, but I don't like the dialer. I have tried a few alternatives and found some I like, but none of them replace the bit that actually makes the calls. When I use, e.g. dialer one, I get a great interface that I like, but the moment I press the call or answer button it goes back to the original interface. Is there any way to completely replace it?
Take the dialer from your old stock ROM, extract from the zip, and install in new ROM. You'll need the app "/system/app-mover", free from playstore, to move stock ROM dialer into the system. Goto settings>apps and disable custom ROM dialer. Your running a custom ROM so this should work, I did this on my HTC.
If this doesn't work out right, just reverse the steps. No damage to the system.
