Annoying iPad Air issue in iOS 11 involving the shake to undo feature.

One problem which I’ve come across on iOS 11 on my iPad Air is what is called the shake to undo feature.
The feature was only supposed to work on iPhones so there is no way of disabling it in the iPad settings.
The feature means that you don’t have to press the lock button to open an iPhone, you can just lift or shake or move your device and it will turn on automatically however this can be quite annoying for me as I like to carry my iPad around with me and constantly having to lock it is annoying.
As there doesn’t seem to be a way to stop this issue, I was wondering if anyone else with an iPad Air noticed this.
