Why is my phone so slow?

The most likely reason that you are experiencing this lagging is because this phone can be operated using different modes. This phone has four different operating modes: Performance Mode, Balance Mode, Smart-saving Mode, and Ultra-saving Mode. Make sure that when you are playing games, you play them on Performance Mode so the game can run more smoothly. Now, be aware that Performance Mode uses the most power, so I recommend making sure that you don't play too long, because then your phone will die: or play with your phone while it's charging.

Although the Performance Mode will help with the performance of game play, the lagging can be helped by simply closing programs and not letting them run in the background when you are done with them. By doing this, you will reduce the possibility of lagging on your phone.
