This wiki page concerns the Samsung Galaxy S4 Value Edition, sold in select areas like The Netherlands. It is structurally the same phone as the Galaxy S4.

The only differences between the two phones appear to be mostly related to the software. The Value Edition ships with a Android 4.4 (instead of Android 4.2). In addition, the VE appears to have a different WLAN module (the Qualcomm Atheros Prima instead of the Broadcom 4335 featured in the stock S4).[1]
