Samsung Galaxy S4
From xda, several users are reporting screen problems of the brand new Samsung Galaxy S4. Problems with brightness and how at certain times the device automatically darkens and brightens, even after having disconnected the automatic brightness option or even the Energy Saving option.
As one Xda user suggests, inside the Snapdragon cpu, there is an option called "BRITE", that seems to work independently of the S4's own automatic brightness function, also contributing that we will have to wait for Samsung itself or an experienced dev to solve the problem, as happened in its day with the Tegra 3
Hopefully this recent problem, plus the strange purple colorations, ghosting and scrolling blur on the S4 screens, make Samsung get the batteries fast and put an immediate solution to these problems, since, in this race to be the best smartphone of the year, where the Htc One X, the Xperia Z and the Optimus G play, it is important that the majority of users remain happy and talk about the benefits of its newly acquired mobiles, ensuring that the S4 does not lose its well-achieved position due to its predecessors S2 and S3.
If some of you are having these same problems that Xda is reporting, tell us about them here.
