I'm working on a hobby project to stick a tablet in a car to replace the factory head unit. For this, I need to connect the reverse camera to the tablet (via USB, using something like an EasyCAP adapter), while the tablet being charged.
So far, I found that Lava SimulCharge adapter claims to do this. Although it's very picky about the devices it works with. (Exclusively a few Samsung Galaxy tabs with strict OS versions and even cable lengths)
I would like to know what other alternatives I have which can do this. (Prefer not being locked down only to the LAVA supported tablets, as they're quite expensive for my purpose.)
Is it a Samsung only feature? (seems like most Windows tablets support this out of the box across a number of OEMs. But haven't seen any Android device that isn't Samsung supporting this.)
Can I check which tablets have the support?
I prefer to do this without rooting the device.
