Graphs of Grafana in mobile devices

I set up a monitoring server with integrated Zabbix and Grafana.

Everything is working properly, but when I try to view a dashboard on a mobile device (android or ios) the graphics do not load.

On android I tested on Chorme, Firefox, Opera, Opera Mini, UC and Dolphin. Just on the Dolphin graphics normally loaded.

In IOS test in Opera and Safari and the graphics did not load.

Is there any solution to this case? Does Grafana work in the browsers mentioned above?

Grafana Version: 5.0.4
Zabbix Version: 3.4.11

Operating system: Debian 9

Thank you very much in advance.

I updated to version 5.2.1 and the problem continues.
Has anyone ever experienced this?
