I can't remember the exact error text but any attempt to install or update an app said something about an error setting up payments (even a free app) and the only way to stop this modal loop was to reboot the device. It's just in a drawer now.
That kind of sums up the general experience I had with the device.
For my wife's keyboard issue it's pretty random, you are typing and then the whole screen freezes for 4 seconds, when whatever you typed while frozen unbuffers all at once. I guess it's some bug in the Vietnamese IME since the keyboard needs to buffer diacritics (I'm just guessing)
> Is that hyperbole? There's a video of a guy putting a headphone jack in an iphone 7.
No it's just how it works in iPhone, full of random suggestions in case anything sticks because nobody has an idea on how it works and there's never any debug info.
Another example, I had another error setting up the dev account, nobody knew what to do, even their own support at Apple!
