@SamsungAdam as I mentioned, It happens at random times. For example, I'm browsing on chrome and it happens suddenly; I switch to another app or go to home screen and the blinking does not go away until it randomly decidesto stop, be it minutes or seconds. It happened in the old phone that I returned and now on the new one that I ordered. Imagine yourself reading or watching something and your hand or anything else gets near the sensor and it turns the display off; do you call that normal? I really don't think so. I did not test it in safe mode because it happens randomly. I don't want to stay on safe mode for a long time waiting for it to randomly happen, that's impractical, I get days without this problem and sometimes several times in one day day. I wouldn't have purchased the second device, but I have invested a lot of money in accessories already so I ordered the new one hoping that it would be better, but it isn't at all. Samsung's policy is ridiculous. They do not have replacement policy even if you receive your brand new phone faulty right out of the box. Your only option is to return it or send it for repair, and both options are time consuming and you will have to wait for a couple of weeks without a phone. You pay $1200 and this is what you get. Complete disappointment.

Having the same issue. It is certainly not normal. I get this annoying blinking at absolutely random times. Like during reading or watching something on the phone and this blinking and the proximity sensor is triggered and when anything gets near to it the display goes off which is not supposed to happen, the proximity sensor should be inactive when you're simply reading something. Also, that blinking is extremely ugly and it doesn't go away even when I switch between apps. It goes away after few seconds at times and after a few minutes at other times. I returned the phone and got a refund and purchased a second one and it has the exact same problem. Nothing about this is normal.
