iOS 11.4 iMessage keyboard and screen problems spreading system wide
Since installing iOS 11.4 my iPhone SE has problems with the iMessage app.
While typing a message the keyboard starts behaving strangely, becoming unresponsive and misaligned with where I tap it. Then the problem spreads to the whole screen and then system wide, with the iPhone opening apps all by itself.
I use the Gboard keyboard and uninstalling this has lessened the problem a lot.
But today, after receiving a quick sequence of messages, the problem reoccurred while using the standard keyboard. However, this time thing got better when I left the phone alone for a minute. (That was not the case while I still used the Gboard keyboard. Even a reset could not solve the problems then.)
iPhone SE, iOS 11.4
