Micromax YU Yureka is not working properly after upgrading. When we place a call, the screen goes blank and I'm not able to receive or decline the call.
I want to downgrade to KitKat, how to do it?
I faced the same problem. Follow these steps and your problem will be solved:
*#*#7769#*#*. One proximity info will come.
I am also a Yureka YU user and am extremely satisfied with AospExtended(LineageOS is also good but hasn't released Oreo yet). I have encountered zero bugs till now and Aosp's Telegram support is also very helpful.
Though this doesn't answer your issue, it's simply an advice for you from my end(because I have been in your shoes). I also experienced some faults in Cyanogen which are now completely gone thanks to these ROMs.
Thank you for your interest in this question.
