I need to bypass the default installed dialler and use one from the Marketplace. (Android 2.3.3 & 2.3.4 - Galaxy S2) The solution I am trying to achieve is for all outgoing calls (not that bothered about incoming) to be handled entirely by a third part dialler such as Go Contacts EX or TouchPal Dialer. The problem I have is that they install fine but when entering the phone number in to the alternative dialler, the default dialler comes up instead after tapping the call button. I have done a great deal of reading on this but the most common quoted solution is not available on either of the two SII's that I have. Going in to the settings/applications/manage applications/all and then trying to clear the Launch be Default is not available (both phones) Installing any third party dialler does not bring up a prompt to select a new default. It is essential for the default dialler to be removed from the calling process and if necessary, will even consider deleting it from the phone and replace with a new file/app in the systems directory. Stumped! Any suggestions/solutions.
