HTC developed several versions of the EVO, such as the EVO 3D and the EVO 4G LTE. The technical specifications vary from product to product, and some models support apps and features that other EVOs don't. To determine the capabilities of your smartphone or to find out if your EVO can run certain software, locate your device's exact product name and model number.
Touch "Settings" from the Home or Apps screen, and then scroll down to the System section.
Touch "About Phone" and review the Model Number field to see the product name.
Press and hold the power button for at least two seconds, and then select "Power Off" from the pop-up menu.
Wedge a fingernail underneath the back of the case, and pull up on the compartment cover.
Remove the cover from the EVO, and then lift the battery out of its slot.
Review the product sticker on the back of the phone to see the model number of the device.
