I released a test version for the rSAP installer app which supports 64 bit Qualcomm phones.
The MediaTek version still doesn't work. I have some strange problems with it...
The 3rd preview of Android "Marshmallow" does no longer contain any hint of the SIM Access Profile, so it seems it was accidently included in the first preview. At least it shows that Google added basic support for rSAP, so maybe more phones will add it in the future.
There is still no solution for the 64 bit incompatibility, but I'm working on the MediaTek version.
The new MediaTek phones with the MTK6732 and MTK6752 chipsets cause problems with my rSAP app when they run Android Lollipop. Android/Linux seems to be running in full 64 bit mode, although the ROMs still contain the unused (?) 32 bit files. My installer app sees the 32 bit files, happily replaces them, and ... nothing happens. The app shows the infamous "is this a compatible phone" error.
The same seems to happen on recent Qualcomm phones, like the Nubia Z9 mini.
The Qualcomm fix should be easy, the MediaTek fix will be a bit harder, because I had to use some "voodoo" to make it work. I'll let you know when I have news.
