Sony Ericsson Xperia X10 mini pro

The Sony Ericsson Xperia X10 Mini Pro is a mobile telephone released by Sony Ericsson on the 24 May 2010.

The device is an upgrade of the similar X10 Mini with many of the internal specifications being identical. The major differences between the X10 Mini and X10 Mini Pro are a slide-out full QWERTY Keyboard, and the Pro having slightly larger dimensions (3.5 × 2.0 × 0.7 inches opposed to 3.3 × 2.0 × 0.6 inches).

The X10 Mini and X10 Mini Pro are designed to look similar and share functionality with the larger Xperia X10, but are internally very different devices. The X10 Mini and X10 Mini Pro lack Sony Ericsson's "Mediascape" media-management software, but include "Timescape" as well as the proprietary "Rachael" UI.

The X10 Mini Pro (as well as the X10 and X10 Mini) runs on Android 1.6, with an update to 2.1 being rolled out from Sunday 31st October 2010, to Tuesday 30th November 2010. The updated Xperia mini pro is more responsive and faster when compared to older Android version 1.6.

The Xperia mini pro (U-20i) has received lot of complaints due to poor built quality. After weeks of usage, customers have reported squeaky back panel. As the plastic parts are not covered under warranty it has become one of the major problem with phone.

Sony Ericsson

Sony Ericsson is a joint venture established on October 1, 2001 by the Japanese consumer electronics company Sony Corporation and the Swedish telecommunications company Ericsson to manufacture mobile phones. The stated reason for this venture is to combine Sony's consumer electronics expertise with Ericsson's technological knowledge in the communications sector. Both companies have stopped making their own mobile phones.

The company's global management is based in Hammersmith in London, United Kingdom, and it has research & development teams in Lund, Sweden; Tokyo, Japan; Mexico City, Mexico; Beijing, China and Redwood Shores, United States. By 2009, it was the fourth-largest mobile phone manufacturer in the world after Nokia, Samsung and LG. The sales of products largely increased due to the launch of the adaptation of Sony's popular Walkman and Cyber-shot series.

Sony Ericsson Satio

The Sony Ericsson Satio (U1) is a smartphone announced by Sony Ericsson at the Mobile World Congress in Barcelona, Spain on 15 February 2009 as the Idou (pronounced "I do"). It was released on 7 October 2009 in the UK in 3 colour schemes: Black, Silver and Bordeaux (Red).

The focus of the phone is the high quality playback of music and video, as well as photography. The camera is located on the back of the phone, behind a slider and features a xenon flash. On the side of the phone, there is a shutter button, and a button which allows you to switch between still and video modes. Next to this is a rocker switch for zooming in and out. Also on this side is a button for playback of photos or video. The other side of the phone has a sliding lock button and a covered slot for a MicroSD card.

The front of the phone is dominated by a 3.5-inch, 16:9 ratio 360x640 TFT resistive touchscreen. There is also a front facing camera for video calling. At the bottom of the touchscreen are three small buttons: green (left), white (centre), and red (right).

In terms of software, Satio uses the Symbian OS 9.4 operating system, which is created collaboratively under the stewardship of theSymbian Foundation. It uses the PlayNow service, Sony Ericsson's mobile content platform, and is part of the company's new Entertainment Unlimited service. In terms of connectivity, it is Wi-Fi-enabled and has a GPS chip for navigation and location-based services. It also supports full Flash for video playback.

The phone was withdrawn from sale in November 2009 by two major British retailers due to complaints from customers. However, the problem was found only in UK editions of the phone and was probably caused by carrier-specific customizations. The following software update released by Sony Ericsson provided a fix and the phone was back for sale at those two retailers.
