mobile phones use IR-based proximity sensors to detect the presence of a human ear. This sensing is done for two purposes: Reduce display power consumption by turning off the LCD backlight and to disable the touch screen to avoid inadvertent touches by the cheek. IR sensors have a number of disadvantages, including high power consumption, high cost, blind ...

I'm sure some of the solutions that were mentioned here will work for other people but unfortunately, the only solution that worked for me was a hardware solution. I took my phone to a lab and they pressed the screen to the back of the phone with some extra glue. After 24 hours the phone was good as new. As a programmer I was disappointed that no software ...

Plug in a headset. It's the only answer!

From what I can see in the video, the fluctuations are within about 1° in the first app, and 0.5° in the second. That's not exactly "random numbers in a wide range". Accuracy within 1° is acceptable for most intended use cases: Mobile games, screen orientation, gestures, etc. It's quite possible that Motorola decided to use a cheaper sensor since the phone ...

If the proximity sensor worked by simply measuring received light, it would be useless at night :) There are various methods this sensor can work, but the main idea is to decide if the phone is being held up at a person's ear. This is a yes or no question so the sensor doesn't have to be able to measure the distance, there just has to be a designated ...

This depends on the device. There are devices that have more accurate sensors, which can display the distance in cm correctly, but some sensors only report the distance as "near" or "far". If your device only gives the two states, Android uses the sensor's maximum detectable distance as the "far" state (in this case, 9cm) and 0 as the "near" state (which ...

The only way I managed to work around this issue with Macrodroid was to: put the trigger to volume button (up) put the action to reject call. So when I make/receive a call, I can end it with volume up button. Works on Z3 Compact.

This is a known problem with the current Android 5.1 update and screen protectors. The problem is related to screen protectors affecting proximity sensing that normally turns off the screen when it is close to your face. There are a couple of solutions: Remove the screen protector Set the Power Button Ends Call setting under Settings > Accessibility.

Proximity sensors allow the screen to turn off when close to the ear during a call. It should automatically come back when it's uncovered i.e. when it's not close to the ear. That said this app seems to promise that functionality -> Smart Screen On Off

Another usage for the proximity sensor is to detect while it's in pocket and disable accidental touch or power button press. Keep screen off when proximity sensor is covered (in pocket) In Moto Gx series (and I believe in Moto Z and Moto X also) if you pick the phone out from pocket or move the phone while it's laying on the table it'll show up the screen ...

I have v. 6.0.1. I contacted support with this problem, since I do not have any proxy setting. Go to settings - > apps -> phone or dial app -> memory -> clear cache and memory and restart your device. This worked for me. Hope this helps, good luck.

Use "Screen On Call" app to keep screen on during call. There is no need to turn proximity sensor off. It will keep working and if you move you phone to your ear, screen will go off, but if you keep it on the table or away from any blocking objects, screen will stay on, so you will be able to use keypad to punch more numbers or for whatever reason you want ...

Feel free to correct me if I'm wrong, but as I understand it, the proximity sensor is what's used in call to stop your face from providing unwanted touch input. It usually glows red while activated and emits infrared. The light sensor is what is used to measure light levels for things like adaptive brightness.

When you get a call in a touch screen smart phone, when your phone get closer to ear or any body part the phone screen get off. That is done by the proximity sensor. Proximity sensor is responsible to heat and when a body part get close to sensor the screen gets off and it prevents accidental touches in the screen. In some smart phones proximity is used to ...

I had the same issue recently, it seems the proximity sensor doesn't work properly and it always see there is something near the phone. During the phone call, this will automatically turn off the screen. I work around this using the app named "Proximity Screen Off Lite" https://play.google.com/store/apps/details?id=com.itsme4ucz.screenoff I configure the ...

Searching all over the web tonight 1/22/21 looking for an answer on how to fix this and found NOTHING. So with trial and error and a little ingenuity I developed my own solution which worked. Turn on airplane mode while the black error screen for in call is opened up on your phone. After the first beep notifying you the the call is losing connection the ...

The latest December 156 MB update seems to have resolved this issue. The problem is with AOSP Phone app. If the latest update has not resolved the issue, install google dialer apk & make it default.

Answer was actually pretty simple. This post suggests a couple of solutions, but the first one worked for me: Restart your phone.

That's because your Proximity Sensor is not working as it should. See Whats the use case of proximity sensor? . This could be due to software or hardware issue To check dial secret code # 0 #. See Samsung Galaxy A8 Secret Codes, Hidden Menu in Samsung A8. After reading the values follow steps here Try fixing with apps like Proximity Sensor Reset App or ...

Have you tested the Proximity sensor on the device, as this sounds like it may be related. Try the following. Menu > Settings > About phone > Diagnostics > Test Device > Tap Ear Proximity If this fails, make sure to remove any covers or Screen protectors and then test again, if it does work, then the Proximity sensor was being covered or obstructed.

You could try this solution to keep screen on during call using MacroDroid automation app (Root not required) To get an idea of how it works, settings required, testing/ troubleshooting, see my answer. Additional setting for this solution is from main panel of app Settings→Trigger Options→ Proximity Sensor Trigger→Enable Work with Screen ...

Using Tasker: Profile name: Screen on Conditions: Call Any, * + Proximity Sensor Tasks Menu (any title, any settings. This is to turn the screen on to show a menu. You can also use Pop-up if you want, though it may not work) Display Timeout (To keep screen on immediately after menu has popped up. Set it to any suitable time you wish to) This worked ...

Open up your Phone app, then tap the Menu/Overflow button and select the 'Settings' action. There should be an option to disable the sensor in those settings. If there isn't, download the Xposed Framework Installer, open it up then select 'Framework' and 'Update/Install'. Reboot, then install the Disable Proximity module. Open up the Xposed Installer again,...

This may be a "duh", but I've found that using a blue tooth headset also prevents this problem from occurring.

Proximity Fix app helped me on Samsung Galaxy Note 2 and in the reviews, fixed it for Nexus 4 as well. Maybe it is worth a try? EDIT: Disable Proximity Sensor AOSP thread may give a pointer on disabling proximity sensor by echo command.

I just checked the Samsung Galaxy SIII Manual which can be downloaded form this site. According to the manual, at least on this mobile phone, the proximity and light sensor are the same physical device. This device is used as a light sensor to increase the screen brightness at night and decrease it during the day, and as a proximity sensor to make sure the ...

If you want to learn whether or not it is caused by proximity sensor you can download this app and see if your proximity sensor is constantly sensing something that it shouldn't. If that is the case, I went through the very same problem and solved it. When I was searching the internet for a solution, someone simply suggested me to Take a little pipe and ...

I faced the same problem but I found a simple and perfectly working solution: Dial *#*#7769#*#* (Proximity sensor calibrator) You will see 2 options Start and Exit Click on Start. Move your finger over the proximity sensor 3-4 times and try to change the value on screen. If values are changing after 3-4 tries then your problem is solved. Thanks to nighil ...

Had similar issue with G2 after display replacement. Unfortunately this could be solved only by replacing the proximity sensor itself (via warranty repair). From the information I found out on the web The most disturbing issue was that I could not unlock the phone in dark light environment (the screen immediately turned off when I tried to go past the ...
