Samsung S4 / Android Messaging issue.
I recently bought a brand new Samsung Galaxy S4 on O2. Everything is working exactly as expecting, except for the messaging app...
I can send text messages absolutely fine; messages deliver near instantly and reach their recipient as intended, however I'm having problems with receiving messages. My phone takes hours to actually receive messages. Whenever I send a text the messages my phone should have recieved hours ago come through seconds after the message delivers to it's recipient. The messaging app is clearly having a problem pushing messages from my network to my phone, but I've no idea how to solve this... :/
Also, this is not a network issue. I have removed the SIM card and put it in another phone and messages come through to it instantly. I also have O2's TuGO app installed on my iPad and my messages are delivering to that on time.
Any help anyone could provide would be greatly appreciated.
