Ambient Light Sensor Issue with Idol 3 4.7"

I have my display set to automatically adjust brightness and pretty often the display goes haywire. The lighting I'm in won't change, but the display will suddenly become much brighter or dimmer than it was a moment before.

Is anyone else having this issue, or do I have a dud?

Battery Temp Sensor Issue after replacing battery

I replaced battery and USB Port on two Nexus 4 phones. Now the battery temperature perpetually reads 28.1C (give or take 0.1).

Battery and USB Port were ordered from FixEZ.com

USB Port replacement fixed original charging issues on both phones, but now have new issues. The new issue is that the phone struggles to top off the battery and make turn off unexpectedly at low battery with red LED.

My best guess is that if the battery perpetually reports 28.1C, then the phone can't compensate for battery temperature during charge/discharge.

I can feel the battery warm up during a charge from low battery (yes the battery, not the CPU) , but the highest I have ever seen the phone report the battery temp is 28.3C.

Assuming that the batteries were counterfeit/defective, I ordered 2 more replacements from FixEZ and started RMA for the first two. The two new batteries were marked differently (different source). I replaced the battery on one of the phones and get the same battery temp value issue.

So now, I'm at a loss what to check/do next. Is the battery temp sensor part of the battery? Or is it somewhere inside the phone and it's supposed to touch the battery?

Searching on battery temp issue tends to yield people with broken temp sensors (too cold). I do wonder if my issue is more common than people realize since I see a lot of nightmare stories about poor performance after changing the battery.

[Q] Sony Sensor?

Hi Guys,

First time joining XDA, have previously lurked on the S3 threads (a long time ago, think it was before knox?). I am awaiting my S6 Edge and was looking at the photo thread of photo's taken with the edge. I noticed some of you guys talking about some sony sensor and did a quick search to find out more, mainly, is this an app or is it part of the hardware? If it is an app, can I install it without root (and tripping knox?). Alternatively could someone point me in the right direction so I can read up on it instead of wasting your time explaining it to me, if it has already been documented.

//Thanks

LG G4 proximity sensor always on when screen is turned off

Verizon LG g4 proximity sensor always on when screen is turned off.

If the screen is on, but before unlock, proximity sensor is on as well. It will turn off only after unlock the screen to home screen.

Will it cause battery drain and infrared light burned out/dead after being *"ON" all the time?

It is infrared, so you can only tell if you use another camera or phone look at it.

Screen touch sensor dead spot

I picked up a N920I in Australia 2 days ago and started noticing that when typing it was very hard to type on the top row of keys. I would often get double presses (tt) or 2 different keys would be pressed (tg).

Often times when scrolling it would also seem like I clicked when my finger didn't leave the screen, which resulted in opening things I didn't intend to like ads, etc.

So I did a sensor test using *#0*# and found there is an area on the screen that is dead or senses very irratically.

Spen works fine and it only is the touch sensor.

Is this a hardware issue and should I exchange the unit, or is this a software bug.?

I'm on DVU1AOH2, updated last night.

How's the fingerprint sensor working for you?

Mine rarely gets it from start, and the usual ratio is 60/40 or even worse.

Which made me ask myself: while setting up the fingerprint, is it better to slightly move around the finger (the unorthodox way), or to keep it as fixed as possible (as per instructions)?

I only have the device for two days, but I will test this and report back the results. For now, the fingerprint system seems crappy and on its way to be declared next to useless. :eek:

Proximity sensor

Hey guys few days back I just flashed new android M build num:MPA44I... It was very good.. But the only problem I'm finding is that my proximity sensor is not working properly during calls !.. As soon as I receive the call and place it near my ears the screen goes off but when I take it off.. The screen won't turn on again !.. I've to manually press the power button !.. It was not happening in my previous lollipop! I'm finding it very difficult to manage during calls !.. Any solution for this ?..


Thx in advance! :)

Oneplus 2 Sensor Issue

Hey Everyone,

The Orientation and Accelerometer Sensor on the Oneplus 2 stops working for some time. But after restarting the phone, it starts working perfectly.

Is it a hardware issue or a software issue?

Is this problem common or should I replace the product?

Why don't we have a gyro sensor?

That's a bummer, the Moto X Play doesn't have a gyroscope, nor does it have a pressure sensor (barometer). Those two sensors are usually included in the lowest priced phone. I guess, it will mean no PhotoSphere and CardBoard for us.

Touch Sensor

I have seen this past 5.0 at times the sensor just goes beserk when typing or browsing starts typing anything clicking on anything and only way to get it to normal is lock and unlock screen, is going back to KitKat the solution ?

LG G2 accelerometer sensor slightly faulty

Since 1 month ago this phone worked really well. But a month ago the accelerometer stopped working, and since then it's on and off...I want to take it to warranty, because I tried three different kdz and the problem still persist so I'm quite sure it's a hardware error.
My question is because the accelerometer works for 1-2 days if you restart the phone, will the guys from warranty have problems in diagnosting the error? I don't want to sent it to warranty just to stay without the phone for 2 weeks and to get it back same way...Here is how the CPU-Z show the problem!

Proximity sensor problem (SMMI test fail)

Hi, I've searched this forum and the Internet in general about proximity sensor problems but it seems like basically every problem that someone else had was fixed by removing tempered glass/screen protectors/cases/covers. I'm having a proximity sensor issue and I'm not using any screen protector or case.

This has happened twice now. Once when I was listening to visual voicemail, once when I was making a call. The screen goes dark and will not respond to any wake commands. Every now and then it will turn on for half a second when I hit the power button but then turns back off again. The first time when I was listening to visual voicemail, I had to hard restart the phone by holding volume up and power. The second time during the call, I managed to hang up the call in the half second the screen came back on, which ended the problem.

Right after that, I tested the proximity sensor using the SMMI test (calculator .12345+=). The test makes you put your hand near the sensor, then away, then near again. During the test, the phone immediately sensed my hand near the sensor except that my hand was nowhere near the sensor and there was nothing else near the sensor either.

I did a reboot and ran the test again. This time, the test finished correctly. The phone did not detect my hand until I actually put it near the sensor.

I'm running stock everything except I do have root(ZE551ML). I'm leaning towards this being a hardware problem and I've only had the phone for a week so I'm well within my replace period with Amazon. Is there a solution to this I'm missing or should I just replace? I'm a firm believer in troubleshooting first. Plus, setting up the phone the way I like again will be a huge PITA.

Thanks.

Camera sensor Sony or Samsung?

Did you guys check the camera sensor on your Edge+? Apparently even this time Samsung is pushing two different models, one from Sony (IMX240) and one it's own ISOCELL sensor. In general, Images from sony sensor have been more eye-pleasing in the past. Would be nice to see how it varies based on model number/region for Edge+, and some sample shots from both.
