|This is a UK phone (although made by a Korean company), but it had Korean in the language options|
As you can see in the picture, the keys are like this:
ㄱ ㄴ ㅏ/ㅓ
ㄹ ㅁ ㅗ/ㅜ
ㅅ ㅇ ㅣ
To type ㅃ, ㅉ, ㄸ, ㄲ or ㅆ, I need to press ㅂ, ㅈ, ㄷ, ㄱ or ㅅ respectively, and then press that '쌍자음' button at the bottom right, which will change the 'single' letter to a 'double' letter.
To type ㅋ, I need to press ㄱ followed by the '획추가' button at the bottom left.
To type ㄷ, I press ㄴ followed by 획추가. I then press 획추가 a second time to change ㄷ to ㅌ.
To type ㅈ, I press ㅅ followed by 획추가. I then press 획추가 a second time to change ㅈ to ㅊ.
To type ㅂ, I press ㅁ followed by 획추가. I then press 획추가 a second time to change ㅂ to ㅍ.
To type ㅎ, I press ㅇ followed by 획추가.
To type ㅑ, ㅕ, ㅛ or ㅠ, I type ㅏ, ㅓ, ㅗ or ㅜ respectively, followed by 획추가.
To type ㅐ, ㅔ, ㅒor ㅖ, I type ㅏ, ㅓ, ㅑ, or ㅕ respectively, followed by ㅣ. So for example if I want to type ㅖ, I first press theㅏ/ㅓbutton twice to get ㅓ, then press 획추가 to change it toㅕ, then press ㅣ to finally get ㅖ.Confused yet?
This system is a little bit too complicated (actually, everything about this phone is really rubbish). My other phone is way more simple, as it just has a 'keep pressing the same button until you get the letter you want' system:
|This my Korean phone (although made by a Taiwanese company!). Cheapest smartphone ever but I love it. Why is the photo so crap? Because it was taken by the other phone above.|
ㄱ/ㅋ ㄴ/ㄹ ㅣ/ㅡ ㅏ/ㅑ
ㄷ/ㅌ ㅁ/ㅅ ㅂ/ㅍ ㅓ/ㅕ
ㅈ/ㅊ ㅇ/ㅎ ㅗ/ㅛ ㅜ/ㅠ
and this is what you get from each key if you just keep pressing it:
ㄱ/ㅋ/ㄲ ㄴ/ㄹ ㅣ/ㅡ/ㅢ ㅏ/ㅑ
ㄷ/ㅌ/ㄸ ㅁ/ㅅ/ㅆ ㅂ/ㅍ/ㅃ ㅓ/ㅕ
ㅈ/ㅊㅉ ㅇ/ㅎ ㅗ/ㅛ ㅜ/ㅠ
But it still has some silimilarities to the other phone's method! Because to make ㅔ, ㅐ, ㅒ or ㅖ, you need to type ㅓ, ㅏ, ㅑ or ㅕ respectively, followed byㅣ. Once you know that, it's easy.
Good luck typing in Hangeul on your phone!
