What is so different about my Pexel7a that's any different to my 5?
Nothing that I even notice. Except for missing convenience such as the rear finger sensor.
And that's the same for most models.
In fact in a desperate bid to make phones exciting again, manufacturers are trying to bring back the folding concept. And that's just going to be a total fad since it doesn't actually bring anything functional to the market.
It's also a bit daft, because not only do they now have your fingerprint, but your DNA and all the other unique identifiers that come with your blood and flesh.
I suspect that it won't be long until they're found, unless they're one of the few people who are totally off the system.
