Source-derived summary

The Xperia X1 (codenamed HTC Kovsky) is a high-end smartphone from Sony Ericsson, and is the first in the manufacturer's Xperia series. The phone was designed and built by Taiwanese OEM HTC. The X1 was first presented at the 2008 Mobile World Congress. The X1 is an arc-slider phone with the Windows Mobile 6.1 operating system. It is Sony Ericsson's first product to run on Windows Mobile. The device also has a Java virtual machine (JBed) and supports Java Platform, Micro Edition that is claimed to have a richer set of features than typically available.

Features

The phone features a three-inch resistive touchscreen overlaying a keypad which emerges when the user slides the touchscreen face upward, much as in the HTC TyTN II, although the X1's touchscreen slides out in an arc. Its touchscreen is a 65,536-color TFT WVGA display. It has a 3.2-megapixel digital camera which records video at thirty frames per second in VGA (640×480) quality. Reviews highlighted camera performance as mediocre and disappointing. There is also a secondary front-facing camera for videoconferencing that is of QCIF format.

The account is most persuasive where Sony, Ericsson and Xperia can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as smartphone model. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q1061068. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2008.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
