Android Controls and Connections
Although the exact buttons and connection ports on your Android device device may vary, there
are standard features common to all models in the Android series of smartphones and tablets. Let's take a look at those buttons, connections and controls and see what they can do.
Connections
Whichever model of Android device you have, it has several ports and other such facilities to connect it to peripherals and also to charge and connect to a computer. It will also, of course, have a SIM card drawer to house the SIM card provided by your mobile service provider. Not every Android model has every port described here.
USB-C/Micro USB
Most modern devices, including recent Android device models, use USB-C connections for charging the phone or tablet and as a data cable, for connecting it to your computer. Older Android phones and tablets might use Micro USB instead. Either way, it's usually found at the bottom of your device.
3.5mm Audio Port
The most recent Android devices forego the headphone or 3.5mm port, as most users today use Bluetooth earbuds instead of cabled connections. If your phone or tablet is an older model, though, you use this port to plug in cabled headphones or earbuds, or to connect to a speaker set's AUX port with a 3.5mm-to-3.5mm cable.
SIM Card Tray
To open your SIM card tray and put in the SIM, insert the thin pin-like tool supplied with the device or a straightened paperclip into the hole at the side of the closed tray. An older Android model might house the SIM next to the battery. If this is the case with yours, remove the battery
cover to fit and remove the SIM.
