My wife bought a new phone, and was trying to use a previous charger and complained the charger's cable did not fit. I'm an electronic engineer and so, you know, errors are not forgiven at home! I said "Don't be stupid, all the world runs on micro-usb". I tried and with a little force it entered, and even charged for a while, then it popped out.
We then noticed the new cable in the box was larger, and realized the phone has USB type C, my fault to not have checked it. So I said in fear: "Don't worry, such an important standard must have been done with retro-compatibility as first thought...". And instead no, all the info I found say the cables are incompatible.
So:
- do you think I may have broken it?
- why did it seem to work for a while?
- may it be that, by chance, they designed it to be safe in case of errors like this?
EDIT Questions were not very professional, so I rephrase:
Does USB type-C receptacle provide a limited / failsafe physical compatibility with micro-usb type-B plug?
