Crash on users device, however it doesn't crash on mine and I have the same device?

Hi all,

I have two issues:

  1. I had a user contact me and send a video showing the app crash to an IQ logo when he performed a certain function. I have the exact same device, yet the app functions flawlessly when performing the same function. 
  2. Another user is saying that he is getting the 'busy' circle show when he tries to install, then nothing after that. App never fully loads. 

Any idea how I can get to the bottom of these?
