This defect is affecting ALL units of the Galaxy A71 and S10 Lite. No exception. Probably due to the super amoled plus display. This is a difficult defect to detect, so many users believe that their device does not have the problem, but the truth is that people do not follow the correct steps to verify the problem.
As I already had 2 units of the A71, I realized that the visibility of this defect can vary according to the device. That is, this defect may be visible in different shades of dark gray, depending on the device. Sometimes the nuances are minimal, but always dark gray. Sometimes, the problem is visible when using apps in dark mode, in other situations, the problem is more restricted.
To check, go to a completely dark room, reduce the brightness to between 5% and 10%, and place the two gray images below in full screen.
Some users of the S20 also have a similar defect, but the discoloration is green. The feedback is that even after updating the S20 to fix this problem, the problem continues. In some cases the problem has been minimized, but it still exists. This is a hardware defect! No software updates can fix it. There is also another problem. When rolling dark images, (mostly black) a bluish drag accompanies the image. Samsung is trying to HIDE the problem, as few customers notice the defect and request a warranty. And if everyone becomes aware of the problem, and requests a change of screen or device, the losses to Samsung would be astronomical. Besides, everyone who has their unit replaced, or the screen replaced, receives the new device with the same defect. And Samsung continues to manufacture new units with the same defect. It's impressive! And Samsung's attendants, as always, are totally uninformed and unprepared. Before buying, I asked technical support if this defect widely reported by users of the A71, was a problem that affected all units, or were isolated cases. The attendant did not answer my question, and just said that I shouldn't worry, and I could buy peacefully because, if the device had such a defect, Samsung would do the repair. Now I ask: Who buys a cell phone thinking about repair? Even so I decided to take a risk and bought it. The first unit I received had this defect. I replaced the device, and the second unit, in addition to the same defect, has a serious battery drain problem, which causes it to discharge about 50% at night, without use. Samsung needs to speak up! And offer a valid solution! Update does not solve, as it is an engineering defect of the screen! They are trying to hide the problems of these devices in order not to assume the responsibility and the costs of repairs. Apart from the irresponsibility of continuing to produce and sell these damaged devices!
My two A71.
