iPhone 5 may get amplified light sensor

According to Apple Insider reports, Apple's not feeling much happy with the functionality of light sensor equipped in its iPhone 4. Albeit, it's still unclear, where the problem lies, a cursory glance  through some discussion boards throws a little light on this issue.

One iPhone 4 user laments, "Whenever I step in from dark to bright environment light sensor works perfect... But whenever I step back from light to dark environment nothing in fact happens. My screen stays very bright forever." 

A reply is put forward that it's "normal behaviour" even though the sensor "is not working as it should". Without any surprise, incorporation of an unofficial case over the light sensor also hinders it from proper function.

As per DigiTimes, Apple could be set to switch to Taiwanese vendor, Capella, which is currently making light sensors for HTC mobile phones. The hardware may be somewhat to blame for poor function, but the controlling software may also be proved responsible. It lies completely in Apple's court, and if so may be a good news for the existing users. But, not forget, it's not the first time an OS update has been solely used to solve a particular issue with iPhone.

The ambient light sensor is one of the simplest yet most handy hardware features on handsets, which decreases the display brightness whenever you enter a darker environment, and vice versa. The iPhone is packed with one since it first launch, as has the cheap iPad and new iPad 2.

Albeit, any hardware change will improbable make it into new builds of current iPhone, but instead would be seen in much-awaited iPhone 5.
