Ever since my 4x HD was new I've noticed a problem, but it's getting so annoying now I finally thought I should do something about it, and I've contacted LG with a view to sending it off for repair:
When I remove the phone from my ear the proximity sensor usually fails to wake the screen back up, meaning I have no controls to end the call with. Occasionally swiping my finger over the sensors at the top of the screen wake it up, but mostly it takes several attempts, and presses of the screen lock button.
SO annoying when you are leaving someone a voicemail and it's still recording, all they hear at the end of the message is the muffled swipe of a finger and me muttering and swearing at the phone as it carries on recording for another 30 seconds or so!!
Anyone else have this issue??

Mine doesn't awake in the end of calls too... but I thought it was normal
We have an option where we can use "Power button" to turn off calls...
I didn't knew that the proximity sensor was suppose to wake up the disply...
Hi Rudeas,
Glad it's not just me!
Where is the option to use the power button to end calls?

Settings/Accessibility/Power button ends call :good:
you can set power cut a call

Maybe a really daft question, but I presume you haven't put a screen protector on that covers the sensor? Stone of the cheap protectors do and that would stop it working properly.
Good thinking, but no, I don't have a.screen protector or anything over It.
To test and eventually to calibrate the proximity sensor, you can use hidden menu (dial 3845#*880#) -> Device Test -> All Auto Test Menu Full -> ALC / Proximity Test.
You can even test the "auto brightness mode" (to test also the light sensor) and "enable proximity wakeLock" (to simulate a call).
To test the sensor just put a finger near the sensor.
There is also a "Calibration" feature to calibrate the sensor if needed.

Wow italianquadcore! That is amazing! Firstly I could see by putting my finger over the sensor how poorly it was working. Often it wouldn't notice I had taken my finger away- then I pressed calibrate, and now it notices instantly, every time!!
Thanks loads, I'm assuming it's fixed now!

Italianquadcore is a lifesaver, right?

Thanx a lot, yah it was a screen protector giving trouble to sensor.
Hi everyone.
I've just bought myself P880 as well. But had the same problem as author. However, the fix to calibrate via hidden menu didn't help at all. My sensor doesn't react at all, however, when I am using a hardware test it shows sensor is present.
Do you think there is something wrong with sensor itself, or there might be some android might have failed to initialize driver?
Thanks in advance!
Mine wasn't fixed by the calibration for long. It soon got worse again, I actually damaged my headphone socket (using a really big headphone plug through an 3.5mm adapter, then accidentally knocking it) and ended up buying a new part from etradesupply.com for about £17. The headphone socket is the same component that contains the proximity sensor, so replacing that fixed it.
I had phoned LG, but as I had bought my p880 from german amazon they said they wouldn't have covered me even if it had been a warranty problem (So much for Europe being somehow unified!) so I had to risk taking my phone apart myself!

Using the hiddenmenu gives me an app crash on v20a when hitting device test, Any fix for that?

It works with V20A without any problems (just tested). Please check if you disabled something, regarding hidden menu or some other related items, in app management.
Thank you italianquadcore!
That solved my issue as well...
Is there such a code for CM?

I just found out that we can assign more fingers to unlock our S5 using finger scanner.
When we are registering the fingers. We are asked to swipe the fingers 8 times.
Here's the trick..Instead of swiping the same finger 8 times, swipe different fingers one by one..and all the finger prints will be registered.
If this was already posted earlier...then my bad
Sent from my SM-G900FD
I don't think that is a viable option. It seems the wizard scans the finger 8 different times so it has a better reading of the print in the event you don't get an exact perfect swipe. The fingerprint unlock is already awful enough and doesn't work too well. Sure, you can scan up to 8 different fingers with the wizard for a single pass, but I think you would have to scan each finger perfectly afterwards to match the way it was scanned into the phone to unlock it Since you can also store multiple fingers, why not just scan the two or three fingers you would use the most and get a more accurate scan possible with the 8 passes?
..
Does anyone have any tips for using fingerprint scanner?
Swiping is originally very bad idea. Samsung missed the point. In iPhone you press button and scan your finger at the same time. So, unlocking made by simple press and hold 1 second to unlock.
What did Samsung is utterly nonsense and inconvenient.
I suggest the opposite : Use all 3 in only one finger. This way phone unlocks only with one finger, but scanner has the best possible recognition.
Every time change the angle of the finger slightly, so to read the finger in every situation.

they could not do anything. apple patented that fingerprint system, the same way they patented "a rounded edged rectangle with a circular home button"
apple copies people but does not let themselves be copied. ... SMH
Hello, I don't know If its supposed to be that way. But when I first heard of the "wide selfie" thought to myself wow I can now take a full picture of the background.....hope turns out I can only turn ONE direction. Not both. And fractly like that its pointless
In wide mode if you start with yourself center frame and tap the camera icon it will instruct you to turn the camera slowly either left or right. If you do so until it beeps you'll be prompted to go the other way to capture the other side. Obviously if you dont go until the opposite direction prompt then the capture will end prematurely and you'll only get half of the shot.
My finger print sensor stopped working yesterday and no matter what I did it just would not unlock my phone anymore as if it forgot my registered print so I deleted the the saved prints on the phone and tried to make a new set but the sensor doesn't wanna read my finger prints. What do I do? This is dumb if I have to send it in for repair cause this is a two month old phone lmao
I have noticed that the fingerprint sensor on this phone is such a piece of ****. After enrolling my fingerprints as usual, the dumb thing unlocked like twice out of ten tries, it made me so mad. This is what I did to get it to work decently.
When enrolling your fingerprint, make sure to
- don't press on the screen, place it as delicate as an angel's kiss
- try to get as many angles as possible, even following the animation when angling your finger
- also try to get it to record your finger perpendicular to the sensor like in this emoji
When unlocking, make sure to
- Try to center your finger as much as possible with the white circle on the display
- If it doesn't unlock right away, keep your finger there for a couple of seconds. Sometimes it does not unlock immediately
Enroll your main unlock finger twice! This is very important to get it to record as much info on each fingerprint as possible. My thumbs are my main unlocking fingers so I enrolled each one twice. Another trick that helped me was to enroll one finger in normal phone holding position, and the other one in more unusual positions like upside down, with the phone flat on a table, and so on). This wasted 4 out of 5 slots though, only one slot is left for a backup finger.
If you apply a screen protector, delete all your fingerprints and enroll them again using the aforementioned tricks.
After doing this it's almost as reliable as a normal fingerprint scanner. Reliability improved from 2\10 to 8\10.
