I can't export the video completely in my mobile it goes till and stops at 15% after that it stops and doesn't work

Is there enough free hard drive space on the disk to which you are exporting?

Hi there,

Are you still experiencing this issue? If so, could you please confirm if you are using the desktop version of Premiere or the mobile version of Premiere? 

Thanks,
Sumeet

Does your device spec match the minimum for the app?

You say ‘in my mobile’ so what program are you using?
