Samsung SGH-T379

From Misc Data Digs

The Samsung SGH-T379, also known more simply as the Samsung Gravity TXT is a T-Mobile exclusive slider phone released in August of 2011. It has an ST-Ericsson PNX6710 System-On-Chip which includes an ARM926EJ CPU.

Hidden Flash Player[edit]

This is in no way documented on any user manual, but this phone actually supports Flash .swf files up to version 7 from the SD card. You can use the number pad or the slider keypad to interact with a Flash applet, and a fullscreen option exists too.

Software Build Date[edit]

This can be found by entering the Admin Setting code at the dial screen, pressing Internals, and then going to Build Information.

Sysol7210 is incorrect, as this device actually has a PNX6710 SoC, part of what is known as the "Swift" chipset.

Software Update Sound[edit]

A "Software Update" function exists in the settings of this phone, but a software update was never released. Thus, the sound that was supposed to play when a software update was available goes unused. The sound is the same as T-Mobile notification sound on modern Android.

It's actually possible to trigger a test software update notification in one of the debug menu options.

Inside of the phone's firmware are 5 valid Adobe Flash .swf files. The 4th file contains credits from someone who potentially worked on the software or the Flash Lite-based UI elements on this phone.
