You have three good alternatives if you want a affordable, good-quality, absolutely awesome android handheld:
- a black GPD XD
- a blue GPD XD
- or a red GPD XD
I don't have a s192, but everything I hear screams it's trash, it's also as expensive as a GPD WIN (which can run pc games...) and doesn't have the nvidia chip anymore in the new units if they are even still made...
When the S192 came out someone got one and found it had two batteries, both were already a year old... other units didn't turn on, broke after two days, etc... it was a disaster.
Get a GPD instead. Seriously.
