The phone features a 3.2-inch 16M-color AMOLED capacitive touchscreen and a 3.2 megapixel autofocus camera. Compared to Sprint's version of the HTC Hero, the device offers a left-sliding QWERTY keyboard with Search Key, four-way navigation with arrow keys, a faster processor, and more available user-accessible memory; however, the Moment has a lower-capacity battery and its touchscreen hardware does not offer multi-touch support. An exclusive custom version with an internal MobileTV antenna and external antenna jack was released in 2010 in the Washington, D.C./Delaware metro area for a public field test of the Mobile ATSC standard.
The base of the Moment's Android 1.5 interface is identical to the unmodified Android install in T-Mobile's G1 phone; built-in software includes Mobile Google services such as Google Search, Gmail, YouTube, Google Calendar, and Google Talk. Building from that, Samsung added Moxier Mail (POP/IMAP Support, Microsoft Exchange access) and Nuance VoiceControl, while Sprint installed NFL Mobile, NASCAR Sprint Cup, Sprint Navigation, and Sprint TV.
In May 2010, Sprint made an update to Android 2.1 (Eclair) available on its website, then announced in June via Twitter that the Moment and HTC Hero would not be upgraded to Android 2.2 (Froyo). A third-party upgrade to Android 2.2.2 was later released in February 2011 by enthusiasts at The Haxung Development Group.
As of the latest Android 2.1 build DJ07, the Samsung Moment, the Samsung Intercept, and the Samsung Transform (all based on the same SoC) do not include support for OpenGL ES 1.1 or 2.0 (in Android 2.2) despite hardware support for it. A community led complete rewrite of the g3d drivers is in development. Samsung Moment and Intercept users have also been reporting issues of data and airplane mode lock up over the CDMA network while using various browsers, streaming software such as YouTube and Pandora, and even randomly for seemingly no reason. The data/airplane mode lock up also prevents making voice calls and forces user to restart the phone to have connections restored. Enabling wifi radio while using CDMA network makes the issue more frequent. GPS has also been a "hit or miss" feature on the Samsung Moment, as some devices have perfectly working GPS, others have semi-working GPS, and yet others have completely dead GPS altogether.
Despite various software updates from Sprint, the previously mentioned issues have remained unfixed on most handsets, leading some customers to believe that the issues are due to defective hardware, rather than software, many customers have pushed to get a replacement phone of equal value from Sprint, but the only phones officially offered as replacements (and even then, only if at least three exchanges have occurred within six months) are the Samsung Intercept and HTC Hero, both of which are considered downgrades to the Moment. Some customers also claim that they were often lied to when confronting Sprint on the issue, often being told that the data lockup and GPS bugs are not known issues, even though the official Samsung Moment update log on Sprint's website lists three different updates meant to address the issues. Customers have also accused Sprint and Samsung of violating FCC regulations, as the data lockup prevents both outgoing and incoming calls, including 911, unless the phone is restarted. It has also been speculated that this is the reason that the Samsung Moment was silently discontinued, despite Sprint's official statement that the release of the Samsung Intercept and Samsung Transform were the reason for the Moment's discontinuation. As support for the Samsung Moment has officially ended, it is unlikely that the issues will be fixed unless by a third-party source.
Third-party development 
Much progress has been made towards bettering the Samsung Moment, with the most prevalent website being SDX-Developers.com. The most important improvement is the port of Android 2.2.2 to the Moment. It offers better memory management, filesystem conversions from RFS to EXT2 or EXT4. These all dramatically improve bootup time and overall speed.
