It would really depend on your device. Since you didn't actually say what device you are using, we would really have no way to answer the question.
So, what device are you using? [/quotemsg
Sorry, I thought I was in a Tom's Hardware forum for the Samsung Galaxy Grand Prime running android 5.1.1. When I registered I assumed all questions pertained to the Samsung Galaxy Grand Prime. Obviously not. Ive looked all over the internet and read the user manual cover to cover and can't find a way to make them lite. Spoke to Samsung 5 times and never could get anyone who knew anything about this. I could barely understand any of them due to strong accents.
