About Keyboard Test
Test every key on a USB or Bluetooth keyboard connected to your Android phone, tablet or TV box.
A keyboard test shows exactly which keys your keyboard sends, so you can find dead keys, sticky keys and keys that double type. On Android it is perfect for checking a Bluetooth keyboard, a USB keyboard on an OTG cable, a tablet keyboard cover or a mechanical keyboard before you buy it second hand.
How To Test Your Keyboard
- Pair the keyboard over Bluetooth or plug it in with an OTG adapter.
- Open the tester and confirm the keyboard appears in the device list.
- Press every key once, then hold a few to check repeat.
- Watch the log for missing keys or keys that appear twice.
Problems A Keyboard Test Finds
- Dead keys that send nothing
- Chattering switches that type a letter twice
- Wrong layout or remapped keys
- Function, media and modifier keys that do not register
If a key fails, clean under the keycap, try another cable or port, and test again before replacing the switch.
