I honestly do not know what Samsung are doing with their selves I now have no data at all since the last update I am bound to just a little at the bottom of the bars and it's been like this since the day of the update 8-in have missed 22 calls today day as I have just put my dog down and people are trying to ring me to say how sorry they are and they can't get through and they've left message after message so now I've got a ***** camera no signal not receiving any calls I've had to go outside in the garden to send this message my data is constantly connected all the time the two little Arrows are constantly on all day long all night my battery used to last 2 days now I can't even get 5 hours out of it there is nothing wrong with the battery before anyone says it's the battery or hold the hold that button or clear your cache or any other and nonsense you got to tell me all I want is a phone I can make phone calls on I can surf the internet and people can actually get hold of me because being self-employed my phone is my lifeline and if I am missing calls this phone is going tomorrow Samsung you need to sort yourself out before you go bust
