I´ve got a problem with moto g android 4.4.2. The connection of data suspends when I switch off the screen. Having my phone with the screen off I cannot recieve messages in whatsapp. I can only receive a message when I switch on the screen and open the application. I checked all the settings, the notifications are on.
They say that this thing can help to fix the problem:
But I realy don´t understand how to install it. Can you please explain to me what to do to istall it?
