4.8 - 4.10 android conversion problem - Resolution

Hello, I recently converted my project from 4.8 to 4.10. Had some bugs, but fixed them, but one bug insists;
When I exported and used my game on the smartphone, everything was much bigger and worse quality (like the widgets, bigger buttons, and everything didn’t fit in the screen).
When I hit play within Unreal everything seems fine, but when deploying it into my phone, everything is big and exceeds the screen.
Is there a new setting for this? Should I change anything?
I think the resolution gets smaller.
Any ideas?
Thanks!

The problem seemed to be in DeviceProfiles… it was treating my smartphone as low-end, while in 4.8 it didn’t, and set the mobile scale to 0.5.
Fixed this by setting it to 1.
