Problem

[tato5DB8]

I am notice that my cell  phone heats up, when I am using it, specially when I used the selective correction.

What can I do?

When you do something on your phone, the processor in that phone gets to work and will generate heat while working. The harder it needs to work, the more heat it will generate. That is completely normal. So as long as the heating up is not excessive, there is nothing you need to do.
