After ios 9 upgrade keyboard freezes and lags in every app

是的，我的电话也一样有这个键盘崩溃问题，而且已经崩溃了很多次，我一个月里已经刷机并设置为新电话很多次，之前在iCloud里关闭那些功能的方案也试过了，的确修复了 一次，然而没过多久，我的键盘又崩溃了。这实在令人讨厌！！

Based on your turning off iCloud services, I was able to reduce the typing lag on my iPad. I don't have an iPhone. However, I am unsure of how far I should go with this: turning off icloud for mail, contacts, and calendars had an effect, but it prompts me about "previously synced iCloud _____" for reminders, safari, notes, and news. I don't know what I will be losing if I do this.

Anyway, this iPad is only a websurfing device and I use web-based email 99% of the time so I think I will kill "news" as it is probably useless. Safari probably should stay. BUT I don't really know what the *&!* "iCloud" is for, anyway? I suppose I should be able to shut it down b/c it's a detriment to performance and then learn how to use it smartly to back everything up every once in a while. Fortunately, this isn't my lifeline to the world, a cellular device, or my main household computer... Any advice on how to use iCloud, whatever the *&!* it is, smartly?

I started having this problem with 10.02 (it happened suddenly on a quiet Sunday morning) and remains after 10.1 update. Only affecting my iPhone 6. 😟

Tried most of the fixes here but the one that seems to be holding and working is to turn off iCloud drive. That's a pain in the proverbial as I now have to go back to emailing stuff to myself to transfer docs iPhone - iPad but at least I can type on my phone again

Only since IOS 10 here... IOS 9.x on my iPhone 6+ was just fine.

Apple needs to get their act together on this SLOWER IOS 10.x on our iPad 4th Gen and others...

Where are they? Amazing SUPPORT! (not).

This is what helped me... I turned Document and Data off and then on again... WORKED 🙂 Thanks

The keyboard was lagging after typing a few characters... Now seems better.

My keynoard freezes, too. What can I do? Does my Applecare help?

im having the same problem, ive been to the apple shop and they have replaced the phones and the problem is still happening, ive stopped sending text messages its pointless, Apple seem to be ignoring the problems. They have asked me to do a full restore as a new phone again, ive done this already and input my contacts one at a time, i have 8000 contacts due to work how is this ever going to work. Apple please spend soem of the billions you have squirrled away on sorting this out
