3G, 4G LTE, WiFi (Direct, hotspot), Bluetooth and NFC are supported while only the infrared port is missing to replace your remote controlers. Standard microUSB v2 connector is built in for charging and connect to PC. Internal memory has 8GB - sufficient for all applications. MicroSD cards go up to 128GB. On 3.5mm you can connect headphones for FM radio. External speaker has 73-74db lodness which is not very loud and it's not worth buying some more expensive headphones.
