Phone only using half screen

I’m making a small first-person project for Android. When I launch it on my LG G2 phone it only uses half of the screen, which isn’t really optimal. Does anyone know what I’m doing wrong?

I think you just need to restart the app

Hey Neshri,

Just wanted to check in and see if restarting the app has helped with the Half Screen issue for you. If the issue is still occurring and you have yet to figure out a solution, you can always post a question on our AnswerHub at and we can try and resolve it for you. Just let us know and we will be glad to help.

Thanks and have a great day!

have restarted it several times, so no that didn’t help. Anything else?
