Android Question Problems with app viewing

[Matteo Granatiero]

for 3 months I developed and tested an app on a galaxy s6 and everything okay, now I've tried it on a huawei and it does not show me the formatting of colors, fonts and more. Why?

Probable causes:

Different android versions
Different resolutions
The implementation code is wrong.

Correct implementation causes similar results on different devices.

Can you post screenshots from both phones?

Android version is 6 for Huawei and 7 for Galaxy s6 , but it worked even when galaxy s6 was version 6.0
