Okay, well I just got a new phone(Optimus l9) and when I add words to the dictionary such as like "Mhm" or "Idk" it will still auto correct Mhm to Hmm, and Idk to Irk even when I added them.. Am I not adding them correctly or what? Like, it shows its in there but when using mhm or idk, it still gets auto corrected.
