Same with russian ‘grandma phones’ with big buttons. Some researches found thst although they don’t provide any functionality besides basic phone\sms stuff, they do try to call their motherbase, sending all credentials and geoloc. IIRC there was no argument about them sending the content of smses and voicecalls, but it’s troubling as it is.
+ Russian as in sold there, they are chinese, sometimes with a local branding.
That doorknob dick.
