I have a little problem with my samsung s3 mini I've only had it for 4 months. Everytime I plugged in my phone to charge sometimes it won't charge and when I plug out the charger the charging icon stays there and the phone keeps saying it's charging when it isn't. I tried rebooting and wiping,when I turn off my phone I have to take the battery out and put it back in for my phone to come back on. Please help
