Regret?....no at all.

Are you owner of one, of this two models?
From where you conclude has a lot of software issues ? 

With C716 ,I have choice to run either Android 9 or Android 11, both with almost no issue (depend on other configuration).
Same apply for P/C725, choice of running ATV or GTV, with either version.

OTA versions is network auto update from other regions, which not (yet) appear here in SE Asia region and is valid globally.

Posting firmwares doesn't mean firmware has major issue.
We have some small group of people, who has access to latest firmware and I posting them here.

Edit:

P/C725 use same firmware as incoming P635/735 and C635 2022 models,

the only regret I have is when I miss to buy it when the price is cheaper 

Any regret?
