64 Bit Lollipop Problems

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.
