I haven't used the wallet before, but I've heard that when you send bitcoins the transaction can be cancelled for a short time.

It mainly depends on the setting: "Tools->Preferences->Transactions->Use Replace-By-Fee".
If it's disabled, the option "cancel (double-spend)" wont show up in the unconfirmed transaction's right-click menu.

On a side note, that behavior might change depending on the Electrum servers and bitcoin node users' decision on "Full RBF" which is already available in the latest version of Bitcoin Core.
If most Bitcoin Core nodes enable the option mempoolfullrbf=1 (which is disable by default), the Electrum setting above wont be necessary.

I use a mobile app. How do I enable it there?
