Why has iOS 7.1 made my iphone keyboard unresponsive?

Mine too. It's awful! I've rebooted a couple of times and also tried restoring the iphone. I'm afraid to update my daughter's phone.

It's fine on my son's ipad though.

Try restarting your device or turning it off then on again, maybe that will help. Personally, my iPod touch 5G keyboard has been fine (actually, way better posting on here on iOS 7.1...iOS 7.0.6. was slow). I also restarted my iPod touch, and it's worked perfectly since then.

Same issue here with iPhone 5 (64GB) - Just got this phone three days ago brand new! Tried restarting it about 10 times, restored from backup and even did an entire factory reset and issue persists. Anyone have any solutions yet?

Other than restarting, I don't have any other solutions. Sounds like iOS 7.1 brought some bugs of its own... :/

It was ckuan who posted that https://discussions.apple.com/thread/5983129?answerId=25129533022#25129533022

Excellent, a big thanks to ckuan!

Can't believe that didn't come to mind... 😊

Thank you Dalesys. That worked!

i had the same problem and i also had shakey/freeze/static-y issues with scrolling in Intagram .. reboot and it seems to be fixed but my keyboard keycaps are now bold .. weird and i cant figure out how to unbold the appearance .. any one?

Just tried reseting keyboard dictionary and restarting iPad mini. At first it didn't work. I contacted Apple support and slow keyboard response was mysteriously OK. About a half-hour between resetting keyboard dictionary and response returning to normal. Beware, it may take a while for this fix to become effective.

I have the same problem on my iPhone 5s 64gb since updating to ios7.1 my iPad works fine though with the update.

My iPod 5 has been so slow and this helped PERFECTLY thank you so much!
