Camera fault ? Proximity sensor fault ? - Huawei MediaPad M5 Lite Questions & Answers

Hi,
Could someone please test something for me ?
- When I set the exposure time to manual, 8 seconds, and take a completely black frame (i.e. the tablet is on its back, so the camera lens is covered) there is a lot of white hot pixels on the resulting photo (white dots). Could someone please do the same and tell the result ? I don't know if my camera is faulty or it's just normal (yes, I know usually tablets do not offer good photo quality, but still... why they allow so long exposure if the photos are unusable - and actually, could come really good with such long exposure?)
- What about the proximity sensor ? it's working in "kid mode", I mean - it's warning when I hold the tablet too close, but then, in normal mode, when I install any testing application and try to test the sensor, its readout does not change - constantly returning 5cm. But, on the other hand, it's reacting when I close the flip cover (screen goes off) and when I open it (screen goes on). Could someone please tell me if their proximity sensor also does not return any readout change in testing apps ?
Thanks a lot in advance !

Hello,
Mine is like that.
-about 20 dots
-5 cm always

Camera Driver yet?

I was wondering if there was any sort of camera driver for download yet, ive been looking all over the site and have yet to find one, and ive looked throughout the internet for one, but Im finding old websites not updated since january....pleeease anybody?
Is this what you are looking for?
http://forum.xda-developers.com/showthread.php?t=355587&highlight=camera
that version is still slow videorendering...
Thanks, it seemed to help out alot in brighter areas but the dark places are still slow... its no problem to me ill just use a dig camera if I need a dark pic... thank you =D
A trick I picked up here with the "new" driver was to turn the camera on. After it comes up, press the power button to put the phone in "sleep" mode. Hold your hand over the camera lens, wake up the phone with the power button, wait 5 seconds and see if the frame rate is a little faster. Goofy trick, but it seems to work.

i found this trick a long while ago. it does seem to work but i dont think it has anything to do with the htc-ca or omnia drivers so even if you dont have them installed, it will work.
I'm using the Laurentius26 V10 ( http://forum.xda-developers.com/showthread.php?t=416278 ) cooked ROM with the HTCA drivers ( see http://www.htcclassaction.org ) and the camera is performing extremely well. There is no evidence of any lag when there is sufficient light available, it seems to still take a performance hit when it has to compensate.
Rob
ps. that trick that p51d007 suggested is completely bizarre! Even the lag with close up or darkness goes away.
i am using the hyperdragon iiir lite rom with the (recomended) radio 1.65.24.36
and the omnia 3d driver installed in it
and video acceleration is perfect!!
a small improovement i have see also in camera
From my point of view... the camera gets SLOW whenever it has to increase exposure to compensate for the dark areas. The power button somehow fixes te exposure... or disables it.
Point is.. although being 3.0 MP...camera quality is nothing like a 3.0 real photographic camera. So... my question is...
Would picture quality get that worse... if the camera would always shoot with a fixed (lets say 1.0) exposure... and then increase the brightness of the picture via software ?
And to be REALLY bold... and please realize that i'm sugesting with virtually or really NO KNOWLEDGE ... 3D graphics can have its gamma controled... at least in a normal computer... how about showing the camera image on a D3D or OGLES texture... and increasing it "exposure" via gamma control ?
(Am i nuts?)
Yeah that trick works, but the picture is darker and a lot grainier. Also if you point the camera to a bright light source, it "resets" and then when you point at dark areas again, it lags. That trick seems to "initalize" the camera to a dark setting, for lack of a better phrase.

Damn, you're right, it resets when you point it at a bright source...I was all excited for a minute, too...
I wonder if there is a way to make the camera behave that way all the time? I snapped a picture with the trick active and it came out pretty good.

Need help samsung galaxy s proximity sensor not working

I need help with identifying the problem why my proximity sensor isnt working. This gets annoying because my phone turns the screen off when making a call and you can turn it back on since it thinks something is all the time in front of it. Is it maybe dust? On which side is the sensor located? Is there any software update for a proximity sensor?
If I type in *#*#0588#*#* that runs the proximity sensor test. The screeen goes green, vibrates and stays on 1 all the time( doesnt flick between 1 and 0 if I i move it). What can I do?
I've got a problem with mine aswell. It is always 0 in the test (it can't sense if i put anything over it).
It use to work but suddenly sort of died. I'm not sure what the problem is too but I would like a fix if anyone can come up with one
Funny thing though, my proximity sensor worked fine for 1 call this afternoon, but failed again soon after. :/
Looks like this is one big riddle for the samsung galaxy users. :/
I made a discovery.. If i shone a bright light on my sensor and held it really close to it (like 0.5-1cm away) then the proximity sensor would react and say something is covering it. Only works with a bright light though :/
How bright is that light? May I ask you what are the other 3 values of your sensors?

hmm it was the flash from my digital camera. I think any decent light would work. Try a torch, if that doesn't work try something a bit brighter.
As for the values, which 3 values do u mean?? sorry
Light, magnetic, accelerometer.
Which rom do you have?

oh, the values for accelerometer work fine, the xyz values react as they should when i move the phone.
Light sensor goes as high as 15000 lux when I shine the light on it.
Magnet sensor: 2 and the xyz change and react as they should. same with Azimuth Pitch and Roll.
As for the rom, I'm on darky's 10.1 Extreme Edition
As I thought my light sensor is also faulty. It goes only from 0-22lux
My solution

I don't know if this helps, I had a similar problem.. After i made a call my screen would not auto turn back on for me to disconnect the call.
It may have been coincidence, but after i disconnected "Increase volume in pocket", everything started working properly again.

Sorry, I should had given this information. This happened on a S4 (I9505) android version 4.2.2.
I don't know if this particular phone has the same menus has mine, but its how i solved my problem.
Having this issue too.
Nothing mentioned so far has worked for me.
Galaxy S4 SCH-I545 on VZW running 4.2.2.
Unfortunately I don't know when it started so I can't pinpoint any apps as possible triggers. However I have tried out all sorts of apps status bar apps, active notifications apps, launchers (Apex is my current now)

Proximity Sensor Issue

I am having an issue where always on display is staying ON while in pocket/faced down on the table. Feels like the proximity sensor is not working while on the AOD.
Plus, the proximity sensor doesn't seem to work while in the pocket either. The setting 'prevent accidental touches' has been enabled, however it is still responding to 'double tap to wake' while in the pocket for whatever reason...
Is there any fix to this?
I noticed the AOD stays on in my pocket as well. I thought maybe it was by design that way, even though it makes no sense.
Have not had a single pocket wakeup though.
It does seem that the proximity sensor (which is really the camera) doesn't work especially well though, from reports of people noticing it on phone calls. Hopefully something that can be fixed in software.

Thanks mate, appreciate your feedback. Proximity sensor works fine on my phone during calls. Can't think of any reason why Samsung would intend it this way...
Proximity sensor issue here as well
I have the same problem. I put phone into test mode and it was bad compared to my wife's s9 search proximity sensor s20fe on YouTube and see others with issue
There is no fix. This is apparently the way AOD works now. I can't remember if it started with the S10s or S20s.

I did some research on s20fe proximity sensor, because I desperately wanted flip case to open and close the screen.
Here is what I have noticed: there are two "proximity sensors" both sides of the front camera. These sensors close the screen during call if you touch them (I'm not sure if it's enough to touch just 1 or do you have to touch both of them). You need to touch these with your cheek or finger cause they need a electric field.
Phone also utilizes front camera light sensor during call: if there is no light, it turns off the screen but for this to happen phone needs to be on up right position. Screen won't close if the phone is on desk and you cover the camera.
So anyways, my point is that the proximity sensor is not able to detect if your phone is in the pocket or not. Only way for the phone to detect this is with the front camera light sensor, and I guess this would increase the battery consumption so much, there is no point.
You can test your "proximity sensors" by typing *#0*# in dialer numpad, select sensors and touch from the side of the front camera. If the screen turns green sensors are working.

I just purchased the Samsung S20 FE 5G UW (how about we shorten this to FE UW?) with all updates AND a glass screen protector and have no touch/proximity issues.
FYI I bought it at the Costco kiosk for a few dollars less per month, no activation charges and a 90 day return policy.
the Galaxy S20 FE (5G) has no physiscal proximity sensor.
Insted it uses a combination of the front camera, touch screen and gyroscope.
I have tested the proximity issues, luckily for me there were ok...turn green. The only thing that drive me crazy is the touch screen issues which never been fixed even after updates. Oh well at least its better than before.

Mate great information here, really appreciate this.
Tested the Proximity sensor using *#0*#, I agree with your analysis. The proximity must be using electric reaction to detect if my ears are touching it or not. Covering it with a book does not trigger a proximity sensor... This explain why my screen keeps waking up in the pocket.
As much as this is annoying, there appears to be no way out Just have to let the phone face outside rather than my legs.
I also have the same issue, while on a phone call, the phone's screen goes on and off constantly and I can see the notification bar moving. Very annoying.
This is a terrible design by Samsung. The punch hole usually goes in the "Empty" part of the ear, so the screen stays mostly on.
I might just return the phone because of this issue, I don't see it getting fixed by a software update.
I have the exact opposite issue with the proximity sensor on my Samsung S20 plus running Android 10 - i.e. it works well by turning the screen off when my ear/cheek/face is very close to the proximity sensor during phone calls; whereas, when the phone's screen is locked and turned off, the proximity sensor is turned off as well. Control by hardware? Software/firmware? Don't know?! To turn the screen on without using the Power hardware button, I had to enable the "Double Tap" feature in Settings.
On earlier/other Android mobile devices - Samsung included - the proximity sensor is always on - whether the screen is on, off, or currently locked. When it's always on, you can be innovative and build a widget, for instance, to turn the screen on by "waving" your hand above the proximity sensor to interrupt the laser. I suspect new(er) Samsung mobile devices like S20 and Note20 variants might be using a "virtual" proximity sensor setup/combo for controlling the device's screen - and that really sucks!
To test if the proximity sensor is always activated on Samsung S20 and Note20 variants, I type *#77692# - which displayed a hardware screen to test proximity and light sensors. Note: if you type *#0*#, the proximity and light sensor options are absent from the hardware test screen.
Has anyone found any method - via codes even - to permanently turn on the proximity sensor, even when the screen is locked and turned off?
I searched through AOSP framework vanilla codes and couldn't see anything out of the ordinary regarding control of the proximity sensor. Samsung might be doing something dubious with their firmwares/hardwares though - well, at least, the S20 and Note20 variants are having issues with the proximity sensor setup.
P.S: Not sure if you guys are aware, but Samsung mobile devices with odd designation tends to be more problematic than their even-designated counterparts, like screen's burn-ins/shadows on Samsung S3 devices, light sensor fluctuation (which affects screen brightness control) on Samsung S5s, and now proximity problems with the S20s and Note20. Samsung S20 variants are in fact "S11" variants renamed. So the trend continues with Samsung always stuffing up their odd-designated device releases.

Disabling Proximity sensor - Nokia 7 plus

Hi All,
I am using Nokia 7 plus for past 2 years. Andorid 10 with Nov security patch. Recently, my proximity sensor stopped working and I am not able to use phone any more (due to black screen during calls). I even root my phone and installed edxposed framework for disabling proximity sensor but no luck. Even sensor disabler not working for me. Any suggestions would be much helpful as I want to use this phone badly
I have same problem (stop working after lcd replace), try more solution, but at end i find one "working"... In Developer options enable QuckSettingsDeveloperTiles/SensorOff, this add Sensor tile to top pulldown QuckSettings menu, before call must you manually enable it, after call disable (because sensor off disable all sensors and also camera ;-)

Yeah, I have been using it. Problematic when attending calls in Skype which wont work unless you switch again. Thanks anyway
In my experience, proximity sensors don't stop working, they just work all the time! Often there's a small rubber gasket which separates the UV LED from the sensor. Can be lost when replacing a screen - I did this myself on a Moto G. Screen would go black in a call and couldn't be unlocked. I found the gasket on the floor, replaced it and this fixed the problem. Replaced the screen on a Nokia 7 Plus recently, same problem. I couldn't find a missing gasket this time, but glued a small piece of rubber between sensor and LED and this fixed the issue. Had to experiment with the size of the rubber piece to get it working properly. I think some of the UV light bounces off the back of the screen and is picked up by the sensor , if this piece is missing. My $0.02 worth...
Guys, I am frustrated with proximity sensor of my Nokia 7 Plus, as soon as I call, screen goes black.
I could stop it by enabling Developer Mode and disabling sensors, but this disables all sensors not proximity, and my camera stopped working.
Can I just remove it from mother board? any way to disable only proximity sensor?
Thanks in advance.

If you've had the screen replaced, I think the rubber gasket separating the IR LED and sensor has been lost. Seems to be a common cause of this kind of problem. Cheers

I guess just the screen turning off during a call. But removing it may damage some other component, I guess. I also wonder if the screen stays off or on permanently if the sensor is removed. If you're taking the screen off anyway you could just try my fix of glueing a small piece of plastic or rubber between the sender and receiver, has worked for me and is still working. But this is just my opinion, all the best in whatever you decide to do. Cheers

One more question
Is there a way to disable only proximity sensor through OS/App? This will save my effort to remove it from board and possible damage to board.
Am working on another 7 Plus which has the gasket fitted to the proximity sensor and took some pictures so y'all can see what I'm talking about. First picture is of the gasket, second is the sensor without the gasket. Cheers
Just checked in to this forum for give Gastrocnemius a big "Thank you"!
We have a Nokia 7 Plus with the "normal" USB connection issue.
Send to repair to an independent repair station (so not Nokia), who offered a good price.
When it came back it looked fine, charging and fast charging was possible, we have been happy.
Until the first call... Black screen with dialing.
A short search showed: many problems after an update, looked like software related issue with no solution.
Shortly after the new USB connection was faulty again.
So the phone went into a drawer and replaced with a new Nokia.
Now my old Redmi 4 is too old and some for me important apps will not work with the "old" android.
I remembered the Nokia 7 plus and started to repair the USB board, also as a trial if i can handle mobile phone repairs for myself. Well, cheap USB board found, change successful... not! Broke the Display (stayed black after assembly, board from display got hot, probably cable broken).
Ok next step, new display, screen works and and charging repaired on first view.
Function check: black screen during call. Tried several proximity fix tools without success.
The app Phone Check clearly identifies as proximity sensor as "close" / near, no change.
The change to far came only when the display was way to the side. So, the sensor is working, but the function close far is not working.
After weeks I discovered this fred! Gasket? Which gasket! There is no gasket! Check with several videos on YT, yes, gasket identified!
So I tried the mentioned fix rubber band but was not able to get it working.
Then I looked for a gasket online and found one available for the Nokia 2 / TA 1007 on EBAY for a couple of Euros and ordered it for giving it a try.
I just assembled the gasket.... the 7 plus no works like new!
So I'm assuming that during the first USB-board change the gasket got lost and the check by the repair company was only performed for the charging and no more checks for the rest or they didn't care (ASUMING!)
Long story short:
If the gasket is missing you can use the one from the TA-1007!
It does look a little bit different than the above gasket but mine worked. No further assembly from the phone is required, just slip it over the sensor (make sure that the big hole is left, seen as microphone is up and sensor is up left [don't know how to describe better]).
Thanks again for the hind to the missing gasket.
Best regards from Munich,
Thorsten

Question No proximity sensor in s21 ultra ?

I feel there is no proximity sensor in this phone..
Becuase while i am on call , even though the screen is touched to my ear , it will light up randomly as i am walking and turning.
Is that function managed by accelerometer and gyroscope as in new redmi phones ?
The autobrightness is also acting weird for me in some cases .

It doesn't do so for me but yes if I move my face when talking the screen turns on but then goes back off immediately. It seems that proximity sensor is managed by the accelerometer combined with ai just like it was in my old OnePlus 7Pro. However, I could be totally wrong!

While on call I tried to use another phone`s camera to search for proximity sensor ( it is ir based , so camera picks it up).
But couldnt find it

So then, my suspicions are right..It's accelerometer+ai
I think it uses the camera too. If you try unlock the phone with the selfie camera covered, it will try to prevent it.
Likewise, if you make a call with your phone placed flat on a surface, you can get the screen to turn off by covering the camera.

Yes it has one. It's near the light sensor... They are both under the display.

I dont think it has .
Even when i am on call , phone just touching my ear , it randomly lets the screen turn on .
Also as far as i remember , always on display in the previous generations used to turn off when the phone was in pocket ( or screen was covered)
But here , the aod always remains on regardless if phone is in pocket or outside .

Yes you are right. It has an ir based one like note 10,20, s10, s20...
Samsung probably is wondering if they should make it invisible with no indicator. That tiny flashing circle has caused more commotion than a midget hooker in the playpen. Every new model provokes this same discussion... talk about a fixation
Using the camera sensor be prohibitive because of power consumption. It would still need an IR emitter to work properly. Net zero gain... and a lot of added complexity at best.
You can test the light sensor with CPU-Z, cover the space to the right of the front camera, that's also what triggers display dimming no matter what adaptive brightness settings you have.
my S20 FE does the same thing on calls. super irritating... i wonder if Samsung will correct the SD card slot omission mistake on the S22. they did the same thing with the S6 and fixed it on the S7
