#DMGC | Modification Google Camera ver. 7.1.015
ver. 0.1 by @the_dise
This is the first build on the new stable version. This is a very raw version, I do not recommend installation, if only as a guide.
What about bugs. Slow Mo, Self-timer, Portrait on the main camera and to all this plus wild lags UI does not work. But the rest seems to work, it was tested on Mi A2.
