Solution – Screen Going Blank During Calls on YU Yureka

Yureka recently started receiving the Cyanogen 12 update based on Android 5.0 (Lollipop). The update has however brought a bunch of bugs with it; one of them is the issue with Proximity Sensor of the device which causes the phone’s screen to turn off during an incoming or outgoing call. The issue was there in the KitKat OS as well, but it was a way less common. Anyways, while we expect YU or Cyanogen to push an incremental update fixing the issue, here’s a possible solution which should help.


  1. Outgoing & Incoming Calls – Screen turns off during a call
  2. Incoming Calls – Screen turns off as soon as you receive a call making it impossible to even pick up the call.

Fixing the Blank/Black Screen Issue

The blank (or black) screen during calls is caused by the Proximity Senor of the phone. It is a hardware issue with the sensor as its detection is not as robust as it needs to be. Calibrating the proximity sensor manually can fix or at least reduce the occurrence of Blank Screen during incoming and outgoing calls. Follow these steps to calibrate the Proximity Sensor on your Yureka.

This only applies to users who have updated to CM12/Android Lollipop. If you haven’t yet, check the update instructions here.
  1. Open the DialPad on your Yureka
  2. Dial  *#*#7769#*#*
  3. In the proximity calibration screen, tap on StartStart Calibration Yureka Cyanogen 12
  4. Wait a few seconds till it reads Calibration Good (in green)calibration good yureka cyanogen 12
  5. Tap Exit and you’re good to go.

That’s it. Most likely you won’t face the issue on the next call that you receive. If you still face it, make sure that there is no dust or screen protector covering the Proximity Sensor. Then restart your phone and consider repeating the steps again.

      I thought the setting was only deployed in Cyanogen OS. Strange to see it working in nexus with nearly stock android.
      But still wonderful to hear that it helped you out. Unfortunately it isn’t a permanent solution.

      Just guessing, it might be a network issue. Does the same SIM manage to do conferencing in other mobiles?

    if callibaration failed what we need to do next?

    • Narender Singh December 26, 2016 at 2:02 am #

      Make sure that no screenguard or dust is covering the proximity sensor on the phone. The proximity sensor is most likely having hardware issues if it still says calibration failed.

  12. Chandrakant December 29, 2016 at 10:48 pm #

      No. It doesn’t require a SIM card to be inserted.
