Android Blurred UI

Hi,

I'm having a problem with UI in my app, the UI looks blurred and the text, input fields and button information looks as if they were lost.
This problem is only on Android, iOS is working fine, and this is not happening all the times, but in some random moment the app loads with this corrupted UI, I've seen the problem in Samsung Galaxy S4, S5, and in some Huawei models.
I'm using the normal Unity UI, and my Unity version is 5.4.1.
Any idea why is happening this or if is a known issue?

Attached to this post are two images, normal and corrupted UI.

Kind regards!
