    Fix NFC image transfer · 629c98c2
    Nick Kralevich authored
    Image transfer over NFC is broken.
    
      STEPS TO REPRODUCE:
      -----------------------------------------
      1. Launch Gallery and open any picture
      2. Keep two devices close each other
      3. Tap on 'Touch to Beam' option on sender device and observe receiver device
    
      OBSERVED RESULTS:
      'Beam did not complete' message showing in Notification window.
    
      EXPECTED RESULTS:
      Beam should complete successfully and able to share picture through Beam
    
      ADDITIONAL INFORMATION :
      Device : Hammerhead
      Reproducibility : 3/3
    
    Addresses the following denials:
