Anker Bluetooth Wireless Keyboard

This keyboard works perfectly on iPad Air, but not so well on Andriod devices, for example Kindle Fire HD and Samsung Galaxy smartphone. When press Shift key with other letter key, does not turn input to upper case. The trick is to press Shift key first and then the letter key. In another words, press them separately. The Caps lock key does not work at all. The trickc is to pressue Shift key twice separately. The following input mode will be in capital case. Make sure the two Shift key presses should be separated, not too fast. When it is time to turn capital case off, type Shift key once.

After multiple tests, it is verified, this issue only happens to some software keyboards, including Go Keyboard. Other keyboards, for example, Hacker's Keyboard works just fine without any issue. Even it happens, it may not happen in some app on these Andriod devices. For example ConnectBob works well after a ssh session starts. In this case, the trick above should NOT be used. In another words, to temporarily switch to capital case, press Shift and letter together. Use Caps lock key to turn on capital case input mode. However, before the session starts, the password input still has similar issue, therefore the tick should be used.
