Whenever I play game, even surfing the internet only, a warning box with highlighted title 'low memory warning ' always pop up. The message mentioned that my memory has been used up more than 90%,and I am asked to clear the memory now. There are two options to choose from, either to clear now or to clear later, I choose clear now. However, it doesn't solve the matter. After a while, the same warning pop out again. I checked my phone ram, I used up about 547mb out of 800mb! My storage memory used up not even half of it! Is there anybody who can help me up with this issue? Thanks for your kindness!
