In my Samsung Galaxy S Duos, a lag is coming after some time again and again. Because of this lag, when I tab any contact for call, the call is not connected immediately. Infact, I have to restart my phone most of the times. If I retap the contact and wait for some minutes or so, it will dial the call and as I disconnect it, it again reconnect it without any further command. I am really pissed off with such a messy behaviour of my phone. Can you please tell me, why all this is happening and what is the solution?

I'm having a problem with accessing or sending messages on Viber. I am normally based in Ireland where it was working fine. I am currently in Italy and none of my messages will send. I have received one message that I have been able to read since I got here. Regarding all my other messages, I get the notification but when I go to read the messages, they are not showing so I can't actually read them. I am connected through wifi. WhatsApp is working fine as is iMessage…so I'm assuming this is an issue relating to Viber or with the handset ?
