The Motorola Droid 4 (XT894) is a smartphone made by Motorola Mobility.{{cite web |url=http://www.phonearena.com/news/Motorola-DROID-4-hands-on_id25683 |title=Motorola Droid 4 hands-on |last=V. |first=John |date=2012-01-10 |work=phoneArena.com }} It was released on Verizon Wireless's network on February 10, 2012 and{{cite web |url=https://www.engadget.com/2012/01/09/verizons-droid-4-finally-official/ |title=Verizon's Droid 4 finally official |last=Gorman |first=Michael |date=2012-01-09 |work=Engadget |publisher=AOL Inc}} is the successor to Motorola's Droid 3. It was released with Android 2.3 (Gingerbread) and can be upgraded to Android 4.1 (Jelly Bean).{{Cite web |title=DROID 4 Upgrades to Android 4.1 Jelly Bean |url=http://news.verizonwireless.com/news/2012/08/droid-4-motorola-ice-cream-sandwich.html |url-status=dead |archive-url=https://web.archive.org/web/20130319012155/http://news.verizonwireless.com/news/2012/08/droid-4-motorola-ice-cream-sandwich.html |archive-date=2013-03-19 |access-date=2013-03-19}} Droid 4 was one of the first smartphones to support GLONASS in addition to GPS.
Processor
The Droid 4 has a dual core TI OMAP processor with 1.2 GHz, updated from the Droid 3's dual core 1 GHz processor.{{Cite web|title=Motorola Droid 4 review|url=https://www.theverge.com/2012/2/14/2797056/motorola-droid-4-review|last=Hollister|first=Sean|date=2012-02-14|website=The Verge|language=en|access-date=2020-05-22}}
Webtop
Similarly to the Motorola Atrix 4G, the Droid 4 had the integrated Ubuntu-based{{citation needed|date=March 2014}} 'Webtop' application from Motorola. The Webtop application would launch when the phone was connected to an external display through a Laptop dock or HD multimedia dock. While in Webtop mode, the phone, operating with a similar UI to one would find on a typical Linux desktop, could run several applications on external display such as Firefox web browser, SNS clients and 'mobile view' application enabling total access of Droid 4 and its screen. In September 2011, Motorola released the source code of Webtop application at SourceForge.{{Cite web|url=http://sourceforge.net/motorola/motorola-webtop/news/2011/09/announcing-the-new-motorola-webtop-source-project/|title=Announcing the new Motorola Webtop source project}}
With the release of Android 4.0 Ice Cream Sandwich for the Droid 4, the Webtop application was replaced with ICS's tablet mode. This allows seamless access to all of the phone's applications without moving back and forth between two user interfaces.
Network roaming
As initially marketed by Verizon, when first launched, the Droid 4 was not capable of roaming in countries with non-CDMA wireless networks. However, after installing the update from Android 2.3 to Android 4.0, global roaming is automatically enabled on the handsets, allowing the Droid 4 to use GSM bands and provide HSPA data connections outside the US.[https://news.yahoo.com/ice-cream-sandwich-arrives-droid-4-enables-global-023504603.html Ice Cream Sandwich arrives on the DROID 4, enables global roaming] However, LTE speeds are only available on Verizon's CDMA network. Unlike previous versions of the phone, the Droid 4 does not have a hot-swappable battery.{{cite web |last=mp107 |date=2019-03-12 |title=Master Your Device |url=https://download.lenovo.com/Motorola/Manuals/77405/593014/DROID4_GSG_Vzw_68016542001b.pdf |page=8}}
Updates
The Droid 4 originally came with Android 2.3 "Gingerbread" out of the box, however, Motorola gradually updated the handset to Android 4.0 "Ice Cream Sandwich" and then finally to Android 4.1 "Jelly Bean". Motorola has also released regular maintenance updates from time to time.{{Cite web|url=http://www.androidorigin.com/motorola-droid-razr-maxx-4-ota-update/|title=Motorola DROID RAZR, DROID MAXX, DROID 4: Update Rolling Out via OTA|publisher=AndroidOrigin|access-date=11 January 2014|archive-url=https://web.archive.org/web/20140110224511/http://www.androidorigin.com/motorola-droid-razr-maxx-4-ota-update/|archive-date=10 January 2014|url-status=dead}}

As of August 2023, an ongoing effort by the Maemo Leste project to port mainline Linux to the Droid 4 supports most of the device's functionality, including voice phone calls and SMS,{{Cite web|url=https://maemo-leste.github.io/maemo-leste-five-year-anniversary-and-chimaera-release.html|title=Maemo Leste - Five year anniversary and Chimaera release|website=maemo-leste.github.io|access-date=2024-01-05}} except for the cameras.{{Cite web|url=https://leste.maemo.org/Motorola_Droid_4|title=Maemo Leste wiki - Motorola Droid 4|website=leste.maemo.org |access-date=2024-01-05}} The Maemo Leste project, funded through NLnet
