nope, clean install of 4.20.3 (and clean install of android works 1R6u1 from extras folder), extracted google sample to my usual projects folder, opened by double-click the uproject. Then i’ve opened the augmented images data asset and cleared it by clicking the bin icon, and then i’ve added there my image (which was prepared as i described above). Packaged for ASTC and installed via USB cable and install.bat. Tested on SGS7 and SGS8.
