Hi, guys So, proximity sensor doesn't switch off screen during calls when it should, causing ending calls in my pocket or opening stuff by mistake when holding the phone to my ear. This is a software bug, not a hardware issue (proximity sensor reacts ok on testing with multiple apps, but not in dialer, where it should). So returning the phone won't result in any benefit on my side, since it won't fix the actual issue. Yesterday I read somewhere on the forums that 3rd party apps might cause these issues, though I was having the same apps on my previous Samsung device, and never encountered such an issue before. So I'm pretty sure this is not caused by third party apps. And so I uninstalled the most recent app that I had installed (again, I had the same apps installed on my previous Samsung phone, and never had this issue): the Google Now Launcher. Then I restarted the phone and the problem was gone. For a while. Today, I had the same issue again. And reading somewhere that a factory reset of the phone will fix the issue, even though I'm not a big fan of redownloading all my apps and setting the phone up all over again, I did it, hoping it would actually fix the issue. It didn't. And not just that it didn't, but it also revealed an issue that I heard about on the news recently, which is OEM ROMs not performing an actual full wipe on /data when the user does a factory reset of the phone. This is unacceptable. And even though this is not related to the proximity sensor issue described in this thread, it's still very concerning that companies like Sony still don't care for user security, or they want its data so much they need to do stuff like this to get it. Either way, not a good thing. UPDATE: after some testing, I noticed the problem occurs in two circumstances: headphones plugged in. Not everyone keeps the phone in their hand while making a phone call. Most people will call using Google Now, or will put the phone in their pockets after the person they're calling has picked up.That's the point of using headphones in the first place (so that you can have your hands free). when the phone doesn't detect movement (I suppose it's using the accelerometer/gyroscope for this, as well). If you just call someone and cover the proximity sensor, without moving the phone upwards, the screen will not turn off, even though you are in a call and even though the proximity sensor is covered (so in theory it should turn off the screen). Not sure if this is ok or not. Anyway, it's less annoying than the first one. And sometimes, even if the user takes the phone to the ear, while in a call, the screen still does not turn off, for some reason. So please, forward this to whomever is in charge of fixing this issue so that they can fix it once and forever. Android version is 5.0.2.
