If the virtual keyboard on your phone is difficult to use with the Google Docs mobile app, and you don’t want to use voice-to-text dictation features of Android or iOS, you have the option of pairing a Bluetooth keyboard to your phone.
Bluetooth is a short-range wireless technology that lets people wirelessly connect their phones to other computers or accessories. Bluetooth keyboards are inexpensive and lightweight, and can easily fit into a briefcase or small backpack. For the Google Docs mobile app on an iPhone or Android phone, serious typing is only possible with a bluetooth keyboard.
After turning on Bluetooth on your Phone (via Settings > Bluetooth) and charging the keyboard, follow the manufacturer’s instructions to pair it to your phone using a special on-screen code. This only needs to be done once; afterwards the phone will automatically detect the keyboard as long as the phone’s Bluetooth is activated and the keyboard has power. The following video shows how to pair a bluetooth keyboard to an iPad running a recent version of iOS:
You can then use the keyboard to type email or use other applications, including productivity apps such as Microsoft Word, Google Docs, PowerPoint, and more. I have heard of students who can’t afford a computer using their phone and a Bluetooth keyboard to complete reports and other homework assignments using Google Docs!
