Have you ever had a stuck pixel? How about backlight bleeding?
With the ScreenTest Cydia app you can fix stuck (out of place) pixels present in your iPhone, iPod Touch or iPad’s screen. Additionally you can test to see if you have backlight bleeding; and if so in what range.
The ScreenTest app works by using a logarithm that operates at a high frequency to excite pixels and hopefully release their stuck state. Another thing to keep in mind is that ScreenTest was designed to be a safe method of fixing pixel related problems. Unlike other applications which use unsafe methods of fixing such problems, the ScreenTest app ensures that the average power requirement to the screen is roughly constant which is safer than other methods.
Note: This app is available in English, Espanol, Deutsch, Francais and Italiano.
