Question: what is the difference between blackberry keyone and key2?
Answer: The screen measures 4.5-inches and has a 1,620 x 1,080 resolution. Like the KeyOne, it has a 3.5mm headphone jack and a fingerprint sensor in the keyboard's space bar. The Key2 is more powerful and has more RAM and storage. Battery life is about the same as the KeyOne, which means the new phone takes the win.
