Re: Charger not connecting
I've had my share of issues with the charge port on my Galaxy Tab 3 8.0, including having it replaced under warranty less than a month in. I think the connector on this device is a bit on the 'delicate' side and will not tolerate any mishandling at all, unlike my wife's iPad Air, which appears to be bullet proof.
You should be able to monitor the charging process in Settings, which will at the very least tell if you if the device is charging or not (there are also apps that will monitor the process, such as Battery Doctor, which is free). Plug the charger cord into the device first, then the other end into the wall socket (while I'll admit it's unlikely, arcing can occur that can damage the pins if it is inserted or removed while the plug is connected to a power source. It's not a lot of current but it's enough eventually blacken the pins, causing problems. It's highly unlikely this could be a problem in your case, with it being so new.). Watch the Settings to see if it begins to charge. If it doesn't, gently move the connector at the device around just a bit to see if it starts charging.
My Galaxy Tab 3 currently has to be positioned "just so" before it will charge (the charge plug has to be angled up a bit), even after having the port replaced by a Samsung warranty station. If the plug is allowed to move from that 'just so' position, the charge process will stop. So, to charge my tablet, I have to put a tube of chapstick under the connector to hold it up at the perfect angle! It's a pain, but it works and unless the port stops working completely, I won't go through the hassle of having it replaced. I'm not sure why but they completely rearranged everything for that repair and it ultimately took a factory reset to get things going again. I was glad to have it working again but I was not in the least happy about what they did to my homepage.
Good luck,
Cheers,

The charger itself is an unlikely culprit in the event of a 'no charge' situation. They're fairly simple devices and seldom go bad.
Good luck,
