****, that must suck.
Well, I have never saw this before and I have no way to fix it, I'd just bring it back to the store.

Ok Samsung, **** you! I bought s7 on 01.04.2016, 1wk later water damage, got new phone after 10 days without it, now this and another 10 days without phone

[Q] Pocket sensor/proximity sensor?

So, I installed Tweaky ROM a few days ago, and since then my phone has been waking up if I take it out of my pocket.
This morning, I noticed that when the phone is locked or on the lockscreen, there is a very faint red light I have never noticed before;
When locked
Screen unlocked
Does anyone know what this actually is? My RAZRi had a pocket sensor, but never did this. Is it just a feature of Tweaky?
Thanks

Red Light near Proximity sensor Always On

First of all I am not talking about Notification light.
A Red light in proximity sensor next to sony logo is always on when device is connected to wifi, or when connected to mobile data only whrn the arrow indicators appears.
This red light is on even if i disable adaptive brightness.
I am shocked why no one raised this quesrion.
Hence here I am.
I hope this is not intentional by Sony.
Coz ffs i cant get one thing to my mind that how it is helpful. It is rather annoying.
Anyone with a clue pls share.

It's on on my phone as well. It was also like that on my Xperia X
I call it the "I'm watching you." light. I think its the proximity sensor's lazer. I dont think it should be on 24/7, but then there is this "Led light's lifetime depends on how many times they are turned on/off" thing. May be it is some kind of an optimisation?

It definitely has to do with data recieving signals.
But whatever it is for I am concerned about battery life
It is just plain stupid of sony to not recognize this.
Coming from z5 I thought speakers were average on z5, but I doubt XZ even have any speakers at all.
Sound is that bad on XZ. I can barely listen to ringtone and I was sitting right next to the phone. What if we are in the other room or @ some distance? We' ll definitely miss the call.
Disable adaptive brightness and the flickery red dot will go off. I can only see it in a darkened room so it doesn't bother me. I'm looking at the screen lol!

so u say that red light turns on only on lock screen...what happens when u unlock the phone is it still on (red light)? becouse mine is always on except when screen is locked and turned off course and then it turns on again when i turn the screen on...this is how sensor should work... If urs doesnt work that way then go send the phone to waranty... I wouldnt investigate anyomre just go to Sony.

Until yesterday it used to be always on, but now only on the lockscreen. It stays off when I unlock the device.
Why can't we seen to find the real use of that light?
Is it even a feature?

looks like this proximty sensor works that way by having red light turned on...so does ur adaptive brightnes still work after it turns off when u unlock the screen?i feel its faulty sensor!i can share u my experience with Z5...i had white spots on screen so i send it to repair and they replaced the screen but also they managed to break proxity sensor aswell... i actualy laughed out loud how can they be so careless ahhh nwm hope u fix it soon.

Well now I get it, atleast I think so.
Red light stays on if we turn on adaptive brightness.
It also turns on when data packets are being sent to our device (via wifi or mobile data)
But why? That is the main question here.
Previous devices never had this feature, and what diff does this make?
Looks like my adaptive brightness works fine.
Do you mean the light in the attachment?
It should be the infra-red light used by the proximity sensor anmd it is not meant to be seen by human. I can only take this from the camera of another device but I cannot actually see it.
Trust me, if you tries to use the camera of another device to view it, you will see it blinks a lot when the screen is on.

That is exactly what I am talkin about.
It is not supposed to be visible for naked eye until you use a camera.
This one just stays on. Doesn't blink.

OK so looks like im having a camera in my eyes LOL cuz i can see that red dot light constantly turned on...ill see what Sony will say about that.im gonna call waranty just for curiosity.maybe they know something
There may be some variation of the wavelength produced by that LED from device to device, while I cannot see it in my XZ, I can saw it in my last LG device. It won't cause any battery draining problem because either you see it or not, it is still blinking.
My God
This is not a problem
By using this proximity sensor our phone controls the automatic brightness setting.
which is called Adaptive Brightness

hey buddy we all know that but we just want to clarify why some ppl can see the light and some not.... read next time
Xperia X and XZs does this and its annoying, Sony obviously did a bad job in defining what's visible to humans.

Phone face down, rings, screen black...

If I have my phone face down on a counter when it rings, when I pick it up the screen is black. Not off, as I see some light, but basically dark.
I cannot see who is calling...can't get it to display.
This actually happens a lot other times. Just now, for example, I just picked it up, and turned it on with finger print. I placed it face down, and picked back up immediately...screen black.
If I happen to have it on and brush the screen across my side, it will go black.
The ringing is the realy annoying one.
Any suggestions? I'm thinking it has to do with something about the proximity sensor sensing the screen against something...but it should let it come on when it's not against something.
Is noone else having this problem? Every time my phone rings, it turns on but stays black. I never know who's calling unless I answer.
I don't know what to do with it. Very annoying.
Hoping someone has a suggestion.
You could disable auto dimming on your phone. Use Lux from Play store instead.

Do you mean Auto Brightness? If so, that is not the problem. I have it disabled and am using an app for brightness control...not automatic.
I cannot find anything in settings about 'auto dimming'.
Thanks for the suggestion though...
You're right. I mean Auto Brightness, it does Auto Dimming too . B.t.w. I don't have this issue.

I'm beginning to think I am the only one.
Another symptom which I am thinking is related. Sometimes when I touch my finger to the fingerprint button to wake the phone, it comes on with that dark screen for just a moment. It feels like the phone is busy, overloaded, or just slow. It will then come fully on. Also seems like maybe it is just in deep sleep and slow to wake up. If I turn it off and back on, it is instant.
I check memory and it always has just under 1.5 GB free.
I don't know what to think, but it is very annoying. I thought about chalking Huawei support, but I'm sureo they'd just say to hard reset.
I do have a lot of apps on the phone, but with that much free memory I wouldn't think that should be a problem.
Another interesting thing related to screen dark: I can have the setting for display to not turn off if no actdivity to 10 minutes, and it still goes off after less than a minute. (Going off is different from the topic of this thread where it is near black/dark, but not off).
I discovered this while trying to use Huawei backup. Thinking of doing a Factory Reset. Instructions say to not lock the screen, so I'm trying to keep screen on w/o my having to hold the phone the entire backup.
This overall topic is making me pretty unhappy with the phone, which I had thought was perfection when I started with it.
sigh...
I finally called Huwaei technical support this morning. They apparently know about this problem, and want me to send the phone back for repair. They expect me to be without a phone for two weeks while this is going on.
It speaks to the reason to not buy phones away from carriers, as anytime I had a problem with my Samsung, they would send out a replacement and then I would send back my old one and I would not have to be without a phone.
Pretty poor .
AN update In case anyone is following this for some reason...
Getting ready to send the phone in, I did another factory reset. I had got to wondering if maybe Gravity Box had been part of my problem. May be the case...not sure. But for now i'm not having the problem. I changed some of the settings on it when I reinstalled. I cancelled the return.
I've had the odd time when the screen is on, but not properly backlit. You can just about make out the screen, but then the backlight seems to rectify itself. It isn't just the Mate 9, but the P10 and probably other phones. Doubtful a hardware issue I'd have thought - rather a software glitch.
The P10 just got an update earlier this week (yet still with April security patches) but my Mate 9 hasn't had an update in months.

P30 bugs

So have a P30 for 2 weeks now and really like it in general just have two little bugs anoying me, one, when turned off if I insert the usb cable to charge...it restarts the phone, two, every morning when I turn it on the screen is in auto even though i always put it in manual
anyone have the same problems?

My phone restart at least 2-3 times per day, every day, since the day i got it.
i'ts not even the same thing i do when it restart. sometime i just open my phone and it restart.
I have spoken with my provider, and they won't do anything until they see it restart when i'm at their shop... but you know, i can't stand in their shop all day long!
i don't think it's the same problem as you, but some of P30 really have a restart issue!
Also my P30 since when I updated to EMUI .124 restart 2-3 times a day. It also sistematically freeze during Antutu stress test (maybe it help you to show to your provider).
I just send mine to be replaced, but I'm worried that also if they replace mine nothing change...
Been using almost 2 weeks on 124. So far no reboots and just ran antutu stress test successfully.
No issues in that regard to my UK purchased device. It's been solid as a rock so far with amazing battery life also.
Maybe there is a lot of p30 with this kind of issue. Let's see how will go the new p30 that huawei will send to me as a replacement.
No problems on my end, except for a blue tint on the recents window. Using a third party launcher. Removing/ disabling Huawei Launcher gives you an older (and in my opinion uglier but better) recents screen back without that issue. Everything works fine so far but they really need to tone down their bloatware. That's the main reason why i dislike Samsung and Huawei.
only one light flashes. only the right thing works for you, how is it?
Fingerprint sensor. Works slow and flashes frequently, Mine got stuck two days ago and even after couple of reboots was still not recognizing anything. Then started working again...

Let us know if it works after replace.. I'm worried that there is a sw incompatibility with something I installed and that nothing change when I will have the new p30. It can happen that one phone have issue, but I already heard 4 case with the same issue!
On Monday I went to the beach with my family, took the phone out to take some snaps of the scenery and the with 3 x zoom, lens had the sun directly on it and the screen started to flash but only when sun was directly on the lens, doesn't sound right to me so am thinking of getting it exchanged. Anyone else had this issue?
I sent my p30 to huawei assistance and they returned back my device with issue not solved. Phone still freeze sporadically.
Hello everyone, i have a strange bug om my p30, i bought my phone a week ago and i'm sure video recording was fine at the beginning, then i applied .124 update and now when i try to record videos it just stop after 1 second, no matter what resolution or format i choose, it happens with back and front camera. I already wipe cache and data of the camera app, but no luck. Videos works fine with other camera apps like open camera etc.. . I spent a week for fine tuning my new phone , so i don't want to reset all. Someone have any other suggestion? Thanks

Did the whole screen flash or just the picture preview? This doesn't sound abnormal to me. The little pixels of the little sensor fill with light super quickly, so of course pointing it directly at the sun will make them overflow with photons and just return a mostly white image

Thank you that makes sense now
Talking to Huawei support at the moment to fix the blue tint (and maybe also WhatsApp notification/ bad video playback performance) issue. They told me they'll reach out to me today.

I have the same problem with my P30 switching back on when charging - I've only been able to overcome this by inserting the charging cable first, then powering off. Not sure about your other problem as my display brightness is always set to auto.

Seems like they fixed the flashing bug with the latest update (.153)
I'm still waiting for it (.153), but as I try to find some logic in it's behavior I guess they tried to make it kind of notification light, but it seems to be unsuccessful.

Verizon LG V50 Proximity sensor problem... maybe

Greetings.
I just picked up the Verizon variant of the V50 and have a question, hopefully someone with a V50 can help me out. My proximity sensor, which is supposed to only be active during phone calls to shut off the screen, seems to be responding to darkness. If I'm in a lit room and the screen is locked, the phone shows the "Always on Display" like normal. However, if I turn off the lights, the screen goes black, the fingerprint sensor does not respond to touch and I have to press the power button multiple times to get the screen to activate. If I turn the light back on in the room, the AOD comes back on and the fingerprint sensor responds to touch.
I took a trip to my local vzw store hoping they would have a V50 on display to test this since I don't know if this is a phone feature or a defect. I'd hate to go through the hassle of swapping phones only to have the new one do it too.
I do have a screen protector on the phone but it is not covering the proximity sensor.
Can anyone with a V50 test theirs to see what happens and let me know? I'd appreciate it.
I just tested this on a Verizon LG V50. Almost pitch black while on a call:
- Screen blanks when I put it up to my ear
- Screen lights up when I pull it away.

Mine works fine when I'm on a call, it's when I'm not on a call. What if you have it just sitting on a table and you turn off lights and make it completely dark in the room? Does the aod turn off or stay on?

Or try this. Have it sitting face up on a table with the AOD on and put your finger over the earpiece/proximity sensor area. Does the display turn off? Mine does and I don't think it should. My V30 didn't.

Sorry, it was late when I responded and I neglected to mention that.
When not on a call, in pitch black, covering the screen doe not blank it out. Only when on a call does it blank when you cover the proximity sensor.

I appreciate your help. What about in regularly lit room? With phone showing the always on display, if you cover earpiece area, does display turn off or stay on? On mine, just sitting on a table in a lit room, and it's showing the clock on the aod, if I cover the earpiece display turns off. Sounds like I might have a defective device.

OK....Let me apologize once more. I missed the AOD part.
AOD turns off when covered regardless of light or dark environment. You want this to happen. The regular home screen does not blank except during a phone call.
You want the AOD to blank such as putting it in your pocket. This is an OLED and they burn. I have a Galaxy S8 where you can see that I used Waze a LOT. I would say that this behavior is normal.
Sorry about the confusion and missing where you asked for AOD.

No problem, thanks for your help. Can I ask one more thing? With the AOD on, with phone sitting face up with no obstructions anywhere and you make it pitch black in the room WITHOUT covering or touching the sensor. Does the AOD stay lit up or turn off?
In that scenario the AOD stays on.
Went in to a room with AOD on. Turned lights off....AOD stays on.
Turned the lights back on and then off to test. It stayed on.
As soon as I cover the proximity sensor with my hand, it turns off.

I have the same problem. And I have already discovered that it is clearly a failure of the proximity sensor since with a sensor testing application it tells me that I have an obstacle 0cm from the screen. Have you managed to fix it?

Try this. Ensure there is no screen protector over the selfie camera. Either cut a relief or use a pre cut protector for v50s/g8x. It worked for me.
Try this; ensure there is no screen protector over the selfie camera. Either cut out/relief that area, use a precut V50S/G8X protector OR no protector at all. It worked for me.
Well this is most common issues with low level refurbs.
Please use this App - it will fix the issue.
