Have you tried contacting Dodger(sic) for advice or a firmware update ?
Their website is in English, but lots of the text is poor grammar, like most Chinese companies. I did contact their support but not hopeful.
And no cellphone company has firmware you can just download. It is always sent through OTG updates. And I already went to the System updates App and installed everything to the latest. Also checked on GooglePlay, I have the latest version of the InfiRay app.
