Hi! I'm new to the "Smartphone", a couple of months ago I got a brand new Samsung Galaxy S 8gb phone and I really like it... but recently I ahve noticed that in the morning it has turned itself off... so I thought the battery had run out... as it wouldn't turn back on. The only way to get it going is to take the battery out! and when I put it back in it showed to be at 71%. This has happened a few times. Have I got a dodgy phone or do I have some setting wrong? Please can you help as this was quite expensive!! Thanks.
