# Introduction
The SX1, released in 2003 by Siemens, is a device that was ahead of its time. It had some unique features that were not common in phones at that time, making it stand out from the rest. In this article, we will take a closer look at the specifications and features of the Siemens SX1.
## Design and Dimensions
The SX1 is a lightweight device, weighing just 116g and with a thickness of 19mm. It has a compact size of 109 x 56 x 19 mm and a capacity of 110 cc. The SIM card slot used in this phone is mini-SIM, which was the standard at that time.
## Display
One of the most interesting features of the SX1 is its unique keypad arrangement. The display is a TFD (Thin Film Diode) with 65K colors, measuring 2.2 inches and having a resolution of 176 x 220 pixels. This display gives a clear view and a screen-to-body ratio of 25.0%, considering the time it was released.
## Platform and Operating System
The SX1 operates on Symbian 6.1 with Series 60 v1.0 UI. It had a TI OMAP 310 chipset and a 120 MHz ARM9 CPU. Though this may seem low compared to today's standards, it was quite impressive back in 2003.
## Memory and Storage
The SX1 comes with a 16MB internal storage, which can be expanded through an MMC slot. It also has 4MB available for general usage. This was quite enough for a phone back then and users could store their favorite music and pictures on it.
## Camera
The SX1 has a single VGA camera, which was considered a high-resolution camera at that time. It also had the capability to record videos, something that was not common among phones back then. However, it had no front camera for taking selfies.
## Sound and Comms
Although the SX1 was not designed to be a music phone, it could still play and record MP3s. It also offered the option to download polyphonic ringtones and had a loudspeaker for audio playback. The phone was equipped with Bluetooth 1.1 technology but did not have WLAN. It also had an infrared port and a radio built-in.
## Additional Features
The SX1 came with pre-installed applications like a clock, alarm, and organizer. It also had a predictive text input feature, making texting easier and faster. Users could create different profiles according to their preferences and also had the option to sync their data through SyncML technology.
## Battery Life and Misc
The SX1 had a removable Li-Ion 1000 mAh battery (EBA-540) that had an impressive standby time of up to 300 hours and talk time of up to 4 hours. The phone came in a sleek and stylish 'ice blue' color, adding to its appeal.
## Conclusion
Released in 2003, the SX1 was ahead of its time in terms of design and features. With its unique keypad arrangement, high-resolution camera, and Symbian operating system, it was a popular choice among mobile phone users. Though it has now been discontinued, the Siemens SX1 will always be remembered as a pioneer in the mobile phone industry.
