Do you have small hand? Xiaomi Redmi 2 4.7″ screen is considered small compare to other smartphones in the market. However, even I cannot reach all 100% of 4.7″ screen with one hand operation. Therefore, MIUI’s one-handed mode comes to rescue. Yup, it will make phone screen smaller to 4″ or 3.5″. You should be able to perform all tasks with one hand then. Of course, the only downside – smaller screen.
