hi. I have been having a problem for ages now where if I use a hardware bluetooth keyboard, often, each letter is input twice when I type. It does not seem to matter what bluetooth keyboard is used, and I cannot see how or why it starts happening. I notice it when trying to actually type text into anything, sms, web pages, passcode, phone numbers, anything. The only way to temporarily sort this out is to restart the phone. It's almost as if the device thinks there are 2 keyboards both typing at the same time. I'd appreciate any help with this. Thanks
I am running the latest ios 10 on my iphone 6S, but it's been doing it since ios 8.
