I see, this device is not on our recommended hardware list - Recommended Android Hardware
That being said, it should work, especially since your content does not seem too demanding and it does work on similar device for you - perhaps there is something wrong with the device itself.
You could take a look at player status screen and CMS logs:
You will want to enable auditing for this display on Displays page in CMS first
Recreate the issue (ie wait for crash)
then check logs page in CMS for errors
Other way would be to install CatLog https://play.google.com/store/apps/details?id=com.nolanlawson.logcat&hl=en_GB (it does require root access though)
you could also check crashlogs on your android device (device -> sdcard->logs->crashlogXXX
where XXX is the crashlog number.
