[4] Galaxy Ace 2 is a 3.5G mobile device that offers quad-band GSM, and was announced with dual-band 900/2100 MHz HSDPA at 14.4 Mbit/s downlink and 5.76 Mbit/s uplink speeds.

There is also a 5-megapixel camera with LED flash and auto-focus, capable of recording videos at QVGA (320x240), VGA (640x480) and HD (1280x720) resolutions.

Trend Plus has Android 4.2 Jelly Bean out of the box, single-core 1.2 GHz processor in conjunction with VideoCore 4 GPU and Broadcom BCM21664 SoC.

The devices are powered by Android 4.0.4 Ice Cream Sandwich, running Samsung's proprietary TouchWiz Nature UX as the default user interface.

[9] Since these phones run Android 4.0, they are still supported by cloud, communications and social networking services that push the latest versions of their apps, which have in some cases been designed with only the newest hardware in mind.

As a remedy, phone owners can replace those apps with less resource-hungry equivalents, or remove them entirely and use a web browser to access the services' sites.
