[Q] NFC from top side? - Xperia Z Q&A, Help & Troubleshooting

Hi,
is it possible to use NFC from top side of device? From back side NFC working perfecty(3-4cm away) but from top cant detect it even if i place it right on the screen... why? Can someone test it?

That is normal, NFC is a very low power standard and the waves don't get through the metal of the mainboard and display (the NFC controller is on the back).

[Q] Home button

My home button stopped working after i installed armorsuit screen protector. i suspect some of the cleaning solution seeped into through the home button. The phone still works fine. i just need to use the back arrow to go back to home. I would like to repair this but i am not sure if the board is part of the usb charging board? has anyone had this issue? maybe that can give me an insight. thanks
Its not a part of the USB/ Charging module. Its a part on the front panel behind the screen... check this video for better clarity

Have you done the exchange before? Does not look that hard as long as you have patience.
Not the home button.

after looking at the video, It looks to me the USB/Charging module contains the micro switch that the home button actually pushes on. The button itself on my phone works, it is just not turning to the home page.
I don't think the usb module has the home button because I have the replaced part with me and nothing is there. So it has to be on the panel.

(Q)Are my phone's IR sensors working correctly

Hello guys
I was just experimenting with moto display of my device and I found this
Is it normal??

Does it happen in ur phone also, please tell, I will ask for a replacement if it's abnormal
By the way the IR sensor's pink color light is visible only if I see them through my other phone's camera.
Sorry for my bad English

Infrared is visible on camera, but not to the naked eye. Any camera will pick it up.

I believe the OP is referring to the completely unresponsive Moto Display when either only both bottom IRs are visible or only his right IRs are visible.
I m not concerned with visibility of IR sensor I m concerned about the fact that moto display activates if i cover the bottom sensors but not if I cover the upper portion of screen
So is there anything wrong with the IR sensors at the bottom part

No there's nothing wrong with anything here. The IR sensors are disabled when the proximity sensor is blocked. This prevents the phone from keeping the IR sensors on while it's in your pocket.
Oh man I m relieved
I was thinking to get a replacement
Thank u all who replied

[Q] IR Sensors Possible Issue?

So the IR sensors on the phone, the ones that are on each corner of the phone and detect movement so that it lights up the active display. Has anyone noticed this? When i wave my hands over the bottom ones, the screen doesn't light up, but if i wave my hand over the top one, it does. Does this mean my bottom ones aren't working? It hasn't really been a real problem, and I'm exchanging my phone for a different color anyway, but wondering if other can recreate this or if it is actually an issue.
Should only take a quick wave of your hand over the bottom bezel of the phone to see if the display turns on. Someone please take a second to let me know.
You have to be a certain height above the lower sensors for it to activate. I have the same issue.
I also have to look at the screen just right to make the screen stay on. Many times it starts to dim while I am reading and I have to adjust the phone. I also have to wave fairly high up to turn it on.

I could be wrong but I believe you have to wave your hand completely over the display for it to function properly. So its not unintentionally turning on with every movement near it. The command is a hand wave over the display, not the bottom of the phone. So I believe its working as designed.

I can make it activate by waving over the bottom half, but only when I do it a few inches above the screen.
i have the same problem.

i can activate the sensors when approaching from the upper part of the screen.
But not from the lower half (sensors below the display).
when seen in very dark room i see all the sensors (upper two and lower two) light up red.
i know that when the upper part of the phone is covered ,the sensors don't work because if the proximity sensor senses dark then it means ur phone is in ur pocket.
should i get a replacement . (really worried)
i did reinstall the moto app, it didn't help.
My Moto X has the same issue.
Edit, covering the top sensor may make the phone think it is in a pocket. I can wave over the bottom of the phone with no response though.

There's nothing wrong with your phone- the "sensors" at the bottom are just flashers and the actual IR receiver is in the top of the phone, so if you wave your hand too close to the bottom the receiver won't be able to pick it up.
Only the top right one wakes the device on mine.
I really doubt it's the IR. I believe it's the camera waking the device.

Why would you doubt something that is explicitly stated by the manufacturer? The IR sensor's sole purpose is for gestures, one of which is to show the Active Display.

I don't think you have a problem. Try this:
If u simply wave at the top sensors, from any direction, the screen turns on.
For the lower sensors, try a bunch of different movements and you'll realize that when you reach for your phone (that means, moving your hand down and approaching the phone from the bottom part) the bottom sensors work.
My theory: the top sensors detect any movements, specially wave (from side to side) movement. The bottom ones detct the "reaching for" movement... If i remember correctly, the little demo you get inside Moto app tells you you can view notification by waving right above the screen or right before you grab the smartphone... isn't it exactly that which we are discussing?
Taking a shot in the dark here, but try going to the "Moto" app, hit the little gear icon top right and select actions. Then select "Wave to silence".
Now test it out, try swiping just above the top sensor (leaving the bottom sensors unused). Now try vise-versa (swipe across the bottom sensors while leaving the top unused). Notice how the wave action DOESN'T work when you isolate the sensors in this way. Now try swiping just above both of them with either your hand or with two fingers, one swiping the bottom and one swiping the top at the same time, you'll notice that DOES work. I think the only time all the sensors are used is for the action of waving to silence calls and things of that nature. When it comes to Moto Display and showing notifications, I'm pretty sure it's programmed to only use the top right sensor, as it wouldn't need three sensors to detect movement. Though I'm not sure why all three sensors come on when the display is off.

Again, there is only one actual sensor, the rest are just flashers, like little LEDs. The flashers send out IR, and the sensor picks it up. What this means, is if the sensor doesn't see your hand (ie, when your hand is only near the bottom of your phone) it's not going to activate anything. The IR flashers essentially bathe your hand in IR light, and the sensor is the component that actually sees it. Make sense?

:good: +1.
I've read the same statement in some technical review.
Can't really remember which ones.
Don't replace your moto X. He's fine.
I've noticed on mine, the bottom two are easily visible in the dark, whereas the top right is barely visible, and the top left isn't visible at all.
I'm not sure if this is affecting the performance or not.

Read the post from MetalHead above yours.
I can activate my screen by waving my hand over the bottom or top portions of the screen.

i did. The top left one doesn't light up at all, unlike the bottom two. This leads me to believe it's non-functioning.

Animation around the camera hole when switching between front and rear cameras

I've had my US unlocked Galaxy S10 for a few days now and one thing I've noticed is that the animation around the camera hole doesn't work when I am in the camera app and switch between the front and rear cameras. Has anyone else had this not work on theirs? Is there a setting that might affect this? I like this animation and want it to work on my phone. Any help you guys can provide is most appreciated!
I was told that led has been removed for now because they made a galaxy case that does some led stuff or something like. They might put it back in an update but no telling when or that's at least what I was told.

Do you have the virtual bezel turned on? Because if you do, that turns off the animation around the camera hole.

I'm not sure what the virtual bezel is so not sure if it is turned on. Where / how do I check that?

If you don't know what it is, then you probably don't have. The virtual bezel is the black bar that covers the hole in the display and pushes the status icons and notifications down. It can be found in display -> full screen apps -> hide front camera

Gotcha! You're right, I don't have that turned on.
