Bob’s having an issue with his tablet. He writes: “When you to to type a letter, the keyboard comes up a numeral. Not in all cases, but it is not possible to log into my e-mail etc…”
Fortunately, that’s an easy problem to take care of. It sounds like the issue is the onscreen keyboard for your tablet. Onscreen keyboards are a bit different from physical typewriter and PC keyboards. On those keyboards, numbers are at the top of the keyboard and sometimes on a numeric keypad off to the right. You also access symbols, by using the shift key and pressing those same number keys.
Since the onscreen Android keyboard is more compact, on many onscreen keyboards, you access numbers and symbols by pressing a key on the left of the keyboard. Sometimes it says 123, sometimes Symbols.
When pressed, it gives you access to a keyboard of containing numerals and symbols.
To return to a letter keyboard, you’ll need to tap the ABC key.
On some keyboards you can toggle between numeric and symbol keyboards to access additional symbols.
Some larger-screen tablets do features the numbers above the letters, more like a traditional keyboard. But those numbers are often quite small and close to the letters.
It’s pretty easy to get a number when you want a letter. You could try to position your finger slightly lower on the screen, if you’re getting numbers instead of the letter you want. Or another good alternative for accuracy is to use a stylus. You could also use voice controls. If you see a little microphone symbol on your keyboard, you can tap that and just speak to your device instead of typing.
