Smartphone Samsung Galaxy S4, which is now available on the market, from the very beginning is not the best streak. Just as there is information that the manufacturer of stuffed its flash memory rather unprecedented in the network already circling another, not so pleasant news.
Novice buyers began to complain about the screen that displaying in full black image was clearly a red glow. It turned out that the red subpixels matrix remain active and preventing blacks. Samsung has responded to the reports and released a special software update. With that, everything now seems to be fine, though, and so you wonder how something like this has not been observed during the testing of the final version of the device.
This is not the end of problems with the screen Galaxy S4, because users have noticed another problem. After updating the system on your smartphone there is something else. As you scroll through the content of a black background, it can be seen that there is a purple glow just before I go black in dark blue. Well you can see it as you scroll through the list of system settings. Scroll the content up and down can be seen as dark stripes and buttons followed by the color variation. The discussion forum XDA Developers you will find that the problem is widespread, so it is difficult to consider this incident.
service Hardware.info got a copy of the Galaxy S4 and confirmed their own tests, the presence of violet glow, which is most evident in the rapidly changing content. For slower scrolling problem is not so much to see and some users may not even pay attention to him. What could have caused? Probably three sub-pixels, red green and blue, do not react as quickly when they have to go from black to dark blue. The appearance of the violet glow can attest to the fact that the red and blue subpixels react faster than the green. Before you light up the latter, the first two will give us is the color purple (combination of red and blue).
is not known whether this problem and Samsung will be able to eliminate through a special software update. What is certain is that its existence has not been found in other products Samsungach, such as Galaxy Note, Galaxy Note Galaxy S II or III.

testing the Samsung Galaxy Note first, we wondered if that’s your smartphone, tablet or rather longer, and we were not able to uniquely classify. Apparently we were not alone: ??after some time, someone decided that this type of equipment worthy of a new drawer. This is how the name phablet , which is a plywood English words phone (‘phone’) and tablet . We had to come up with something, because Samsung’s experiment was a great success, which initially was not expected.
processor is the heart of your computer. When performance is not enough, not only complicated tasks are performed slowly, you can not wait any longer, for example, to open the program. Additionally, the graphics card has a decisive impact on the number of frames per second in games. Today – as the “end of the world” – present a great test of processors from AMD and Intel. Great, I were in the 160 models, each of which has been described 52 results. If added to the measurements in the settings cranked up, the total result is 12000! You will not find a larger test of processors. Which is the best for gaming? Which is the best value for its price? Which one should I buy in different price ranges
