They all use the base package from the chipset vendor. It only supports android and only for a given number of years. I wouldn’t be surprised if the license was massively invasive.
Basically, there’s no drivers and no documentation for most mobile hardware outside of manufacturer contracts.
Is the PSU in V2 any less shady than in old Enders? The almost naked industrial unit was easy to install with wrong screws that reach into the circuit board or have things fall into the contacts or through the slots inside.
I’d look at the cable and the switch and any connectors and connections there first.
