I have been facing the problem of not being able to do a conference call as the SM-G900S model does not allow a merge call facility. Have been trying to flash the custom roms, but to no avail. So just had the idea of installing the phone app standalone from any other ROM. Thankfully Samsung allows us to change the phone app- so I am thinking that if I do a custom install from any one of the roms - this should fix my issue.
So my question here is - which is the .apk file which will install a phone application for me ? I have come across the phonesky.apk - but I think this wont do the trick..
Any suggestions ?
Thanks & Regards,
