Two days ago my phone started to give me a problem. The phone I'm using currently was a Samsung Galaxy S Plus phone. It started giving me a weird problem for instant blinking blinking and beep beep sound continously while stating MTP Application error or something like that. 

Once in a while it will come out PC idle or something like that. The media scanner keeps on scanning for no valid reason. 

What the heck was that? Virus or software error? 

Anyone good Samaritan can help me solve the problem in a simplest way possible. Thanks in advance!

What does that mean?
