The HTC Evo 4G (trademarked in capitals as EVO 4G, also marketed as HTC EVO WiMAX ISW11HT in Japan) is a
History
During development the device was known as the HTC "Supersonic"; however the device was rumoured before it was officially announced. It was known as a variant of the HTC HD2 running Android.
The EVO was released on June 4th, 2010 in the United States (through
Features
The HTC EVO features hardware very similar to the HTC HD2, a smartphone running Windows Mobile.
Screen and input
The EVO had a 4.3-inches (480x800)
The EVO featured seven hardware / touch sensitive buttons, four of which are on the front of the device. Input and interaction with the device required users to use hardware/touch sensitive buttons often throughout Android OS. Like most Gingerbread Android devices, the EVO features four main touch-sensitive buttons on the front — Home, Menu, Back and Search. The Home button returns to the home screen where applications can be launched. The Menu button shows menu options in various applications although it can also be used for other purposes, the Back button is used to return to the prior page or screen displayed, and the Search button mainly allows searching through the phone but can be used for other purposes in various applications. The volume adjustment control is located on the right spine. A multifunction sleep wake button is located on the top of the device, which serves as the unit's power and sleep button and also controls phone calls.
The device responds to four sensors. A proximity sensor deactivates the display and touchscreen when the device is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs via users' faces and ears. An ambient light sensor adjusts the display brightness, which in turn saves battery power. A 3-axis accelerometer senses the orientation of the phone and changes the screen accordingly, allowing users to easily switch between page orientation modes. A geomagnetism sensor provides orientation with respect to Earth's magnetic field. The proximity sensor and the accelerometer can also be used to control and/or interact with third party apps, notably games. The device also contains a temperature sensor used for monitoring the temperature of the battery.
The device also features a
Processor and memory
The EVO is powered by the
It features 512 MB of eDRAM and also features 1 GB of built-in ROM that is mainly used for the system software.
Cameras
The EVO features a rear-facing
8-megapixel camera capable of recording videos in 720p at 30 frames per second and dual photoflash, which helps to illuminate objects in low-light conditions. In addition, the front-facing camera array has a 1.3-megapixel sensor in front of the device designed for use with video calling and for taking portrait images, although it can also be used in other applications. The front facing camera does not work on any versions of Android higher than 2.3.7 Gingerbread.Storage
The HTC EVO 4G features a microSD slot in addition to the built-in ROM that allows for user-expandable storage. The device supports microSD cards of sizes up to 32 GB. With Android version 2.2+ (Froyo) available as an over-the-air upgrade, the OS supports applications that permit themselves to be installed on the SD card.
The device comes pre-installed with an 8 GB
Audio and output
The rear of the EVO has a speaker that is used for most applications, this is the main speaker. A loudspeaker that serves as an earpiece is located above the screen. The microphone is featured on the bottom of the phone and is usually used for phone calls and voice-commands, although it can also be used in many other third-party applications. The unit has an HDMI-out (type D, micro connector) port, which allows sending content to an HD television set. The Sprint Mobile Hotspot application allows sharing the device's mobile broadband with up to eight devices.
Smartphone connectivity
The EVO features a
Battery and power
The device comes pre-installed with a 1500 mAh Li-ion rechargeable battery that is designed to be user-replaceable. The battery is interchangeable with the
Software
The device has the
The EVO has also seen support from the developer community with Android versions including Ice Cream Sandwich 4.0, Jelly Bean 4.1 - 4.3, and finally KitKat 4.4, some of which are available with HTC Sense while other available versions are based on stock Android. As of the end of 2016, there is very little, if any, support from the community due to the age of the device and the fact that more recent versions of Android (5.0+) on this device may not run.
Interface
In HTC Sense, the interface is based around home screen panels which in total are seven panels that allows user-customization. By default, the center home screen panel features a digital clock located on the top of the screen and weather animations of the current weather in the device's location, the remaining space in the bottom can be customized to user preferences. The launcher, located at the bottom of the screen, displays icons to open the App Drawer, Phone application, and the ability to add widgets on the Android desktop, and is shown throughout all seven home screen panels. Users can switch from one panel to another by sliding left or right. A small bar that sits on top of the launcher represents the current panel the device is viewing. Pinching the home screen (or pressing the home button if the user is on the center panel) brings up Leap screen, showing thumbnail views of all the home screen panels and allowing users to "leap" to another home screen panel easily. Unlike other custom user interfaces for the Android OS like Samsung's TouchWiz UI, HTC Sense does not allow disabling or removing a panel.
Most of the input on the device is given through the touchscreen, which understands complex gestures using
Criticism
30 frames per second cap
Some users have experienced noticeable graphics lag and/or slowness while using the phone.[15] Various reports throughout the Internet indicated that the device may have a 30 frames per second cap. An HTC representative announced that it was a hardware cap, not subject to software updates.[16] Despite the repeated claims regarding the supposed hardware cap, HTC released an update on September 22, 2010 that, among other things, removed the 30 FPS cap.[17]

Screen
There have been many problems with the screen. Some of the first customers complained of screen separation; HTC acknowledged the problem and was able to limit the number of affected units.[18] Another problem with the screen is a bright spot in the lower area of the screen. This is commonly referred to as the 'B-spot' or 'B-spot problem' due to the bright spot sitting at the location of the B key on the default on-screen QWERTY keyboard.[19] The bright spot is only noticeable when the screen's brightness is turned up and the content is light/white. This 'B-spot' may also become visible when the display is set to automatic brightness.

The device clock is 15 seconds faster than
Battery life
Users have complained that the battery life for the Evo 4G is inadequate and incapable of lasting one day of normal use.[22] This has spawned the creation of pages dedicated to explaining how to optimize the battery life,[23] and even an aftermarket extra large battery that enlarges the unit. In addition, there is a software error that causes a severely depleted battery to become unable to be charged in the phone. The OTA upgrade to Android 2.3.3 fixes this issue along with improving device battery life on the whole.
Design
The EVO's design is derived from its Windows Mobile-based brother, the HTC HD2, which also has a 4.3-inch (110 mm) multi-touch capacitive touchscreen, nearly the same slim profile, and the same placements of most general components and buttons. Although similar, the EVO has features that distinguish it from the HTC HD2 including the front-facing camera, the circular-shaped rear camera, an integrated
Kickstand, and touch-sensitive buttons instead of hardware buttons. Another feature is Android-specific buttons. The device has nearly the same dimensions, namely
122 mm (4.8 in) high
66 mm (2.6 in) wide
12.7 mm (0.50 in) deep.
Warranty
The phone comes with a one-year warranty, which does not cover scratches, cracks, smudge marks, liquid damage, and other forms of physical damage. Sending phones for repair is typically handled by the phone service provider, rather than through HTC.[24]
