The Motorola BackFlip and Sony Ericsson Xperia X10, both released in 2010, represent distinct approaches to smartphone design and functionality. Although both devices utilized GSM / HSPA network technology and supported 2G and 3G bands, key differences emerged in their physical attributes, display capabilities, and operating systems.
Motorola’s BackFlip, announced in November 2009 and released in March 2010, featured a unique design with a side-sliding QWERTY keyboard, dubbed “BACKTRACK.” The device measured 108 x 53 x 15.3 mm and weighed 133g. Its 3.1-inch TFT display offered a resolution of 320 x 480 pixels and a pixel density of approximately 186 ppi. The BackFlip ran Android 1.5 (Cupcake), upgradable to 2.1 (Eclair) in the USA, and was powered by a 528 MHz ARM 11 CPU with an Adreno 130 GPU, alongside 512MB of RAM. It included a 5MP camera with LED flash and a microSDHC card slot with a 2GB card included.
In contrast, the Sony Ericsson Xperia X10, announced in January 2010 and also released in March 2010, adopted a more conventional form factor. It measured 119 x 63 x 13 mm and weighed 135g. The Xperia X10 boasted a larger, 4.0-inch TFT display with a resolution of 480 x 854 pixels and a pixel density of approximately 245 ppi, protected by scratch-resistant glass. It ran Android 1.6 (Donut), upgradable to 2.3 (Gingerbread), and was powered by a 1.0 GHz Scorpion CPU with an Adreno 200 GPU, and 384MB of RAM. The Xperia X10 featured an 8MP camera with LED flash and a microSDHC card slot with an 8GB card included.
Both phones supported Wi-Fi 802.11 b/g and Bluetooth 2.1 with A-GPS for positioning. However, the Xperia X10 offered additional features such as DLNA and a hotspot capability. The BackFlip included stereo speakers, while the Xperia X10 had a standard 3.5mm jack. Both devices utilized a Mini-SIM card.
The Xperia X10’s chipset, a Qualcomm QSD8250 Snapdragon S1, provided a more powerful processing capability compared to the Motorola BackFlip’s Qualcomm MSM7201A. The Xperia X10 also offered video recording at up to 720p with a software update, exceeding the BackFlip’s CIF@30fps capability. Both devices featured user interfaces distinct to their manufacturers: MOTOBLUR with Live Widgets for the BackFlip and Timescape/Mediascape for the Xperia X10.
Both the Motorola BackFlip and Sony Ericsson Xperia X10 have since been discontinued, representing early iterations of the Android smartphone landscape.
