unresposive letters when i try to write a txt message

Hi tonystorm,

If you are having issues with your iPhone onscreen keyboard sometimes being unresponsive, you may want to try some things to troubleshoot.

First, quit all running applications and test again -

Force an app to close in iOS

Next, I would try restarting and if needed resetting the iPhone -

Restart or reset your iPhone, iPad, or iPod touch

If the issue is still present, you may want to restore the iPhone as a new device -

How to erase your iOS device and then set it up as a new device or restore it from backups

Thanks for using Apple Support Communities.

Best,
