I'm a newly arrived escapee from the iPhone Empire - I just got a Galaxy Ace and it seems better in all respects except one very important one for me... I used to use my iPhone to write / take notes etc, using an I-connex Bluetooth keyboard. But it looks like my Ace won't allow this keyboard to connect - it says it doesn't connect to HID devices.

I've tried two different apps to try and fix this - BlueKeyboard JP (which only works with certain keyboards, not including mine) and Bluetooth Keyboard Easyconnect (which I think requires my phone to be rooted - at any rate, it doesn't work).

I'd be very grateful for any suggestions how I can fix this, as it really makes the phone seriously less good than what I had before, given how I use it! Failing that I'd be very grateful if anyone could advise me if there is any version of Android that DOES allow HID devices to connect - and what phones run it.

Your device does include bluetooth support, however not the HID profile (with the Android version it runs). I only see 3 options: a) Wait until Samsung launches a firmware update (not happening, alas). b) Install a mod (Howto‌​, download here or search XDA). c) live without it?? – ce4 Jul 9 '12 at 10:20

Bluetooth was enabled early on in Android (1.5 or 1.6 iirc) So any limitation in that regards is from your specific device and not the platform itself.

I have successfully used HID bluetooth devices with: Samsung Galaxy Nexus, and HTC Evo 4g LTE, Toshiba Thrive, Acer Iconia A200.

I was unaware that there were any devices that disallowed HID device connections actually.

In general though Nexus [anything] devices are the least limited devices on the market at any given time, so I'd say you can't go wrong with one of those.

Bluetooth HID support was officially added to Android in Honeycomb 3.1. Any device that uses either this version or Ice Cream Sandwich (4.0 -> ) or Jelly Bean (future devices) supports Bluetooth keyboards out of the box.
