Yesterday I got an update to upgrade my Micromax Yureka mobile to CyanogenMod 12 which upgrades the Android version to Lollipop. And from then I am unable to pick calls, as nothing gets displayed/or rather display won't turn on to pick up the call.

I installed a sensor test app and found that the proximity and light sensors are not working. I removed the screen protector as well. Can someone please suggest a fix for it?

  • Which ROM did you upgrade from? You may need to flash an updated modem.
