I have a HTC Desire 816 which is running Android 4.4.2 and having some issues with the touch and the camera.
The main issue is some places of the touch screen is not responsive or it needs to tap couple of times to detect the touch. As you can see (following image) the center of the touchscreen having some issues.

Other issue is the rear camera. It's completely dead sometimes and if I hit the camera section with my finger, it's working sometimes. However the image quality is very low seems like it has a stucked lens or something? Front camera works fine and shoots good photos.
Next issue is with the flasher flasher works fine when I take photos with the rear camera when it works. However, any of flashlight applications were NOT able to power it up unless the camera.
Someone have tried to open this phone to remove a stucked SIM card and have damaged the logic board as you can see below. However, all the parts, sensors, mics, speakers close to this section is working fine (front camera, microphone, led, proximity sensor, light sensor, earphone jack). Any ideas about damaged section? will it causing above issues? Please help me guys...
Nobody?

I have Motorola Defy MB525. A Strange issue surfaced recently. The Proximity sensor is behaving weird - It works sometimes and doesnt sometime!
Sometimes even after the call, the red color sensor keeps lit until I pass my finger over it to close.
As soon as I make a call, the display turns off completely and I am left with no option to turn the screen ON to disconnect the call or do any other task. The moment the call gets disconnected, the light turn ON back.
The situation is weird and I am sure its something related with hardware as I tried various other ROM and its the same result in each ROM!
What I need to ask is, whether there is any method to turn off the sensor completely? Or I should just smash that sensor to make it go die and non-functional?
The sensor is attached to motherboard and not a separate hardware at motherboard unlike camera and other stuffs.
Any suggestions or ideas to overcome this strange issue?

There are some reports that turning the screw behind the Proximity sensor half a turn would fix the problem.
Camera problem: red/blue/purple noise in low light photos
Same story from M7 continues with M8. Taking pictures in low light has red/blue/purple noise/tint.
Here is video sample:

You can clearly see on video and picture heat shielding starts degrading, thus parts of the heat transfers to sensor.
Mine M8 produced in May 2014, serial number HT45.
Sensor is Omnivision OV4688 4M.
You can check sensor via file manager, no root is required.
For example, in Solid explorer:
Choose System Root - Sys - android_camera - sensor - open as - Text file - SE TextEditor.
Please report if you anyone has such issue.

Im interested in buying this phone so while researching about features i noticed two things:
1.
On the official Xiaomi website it doesn't say that the phone have barometer and everywhere else it says it has;
2.
In some videos featuring the camera module it says that the forth empty camera slot is ToF 3D sensor
(I want to know is it only for show or maybe it has some other sensor?)
If someone can test if the phone have both of this features (or doesn't have) it will be greatly appreciated
Thanks and sorry if i wasted your time

As for #1 im not sure. Why would anyone need barometer sensor anyway... But it's possible that it has it
As for #2, it has some chip under that part, so it very well could be that sensor...
Thanks for the answer, upon further research including here i found that there is no barometer sensor, now if only could someone answer what is that sensor under the fourth "camera" hole.
(My dilemma is if should go for this phone or F2 pro)

Click to expand...
Click to collapse
It's not camera, its light sensor hole.
Hi, I received my new Xiaomi 12X today and noticed that the LED flash on the camera works only upper side as you can see in the photo. It is normal? Shouldn't both LEDs be lit? Maybe someone can check on its 12X does it work in the same way?

Almost became blind while checking it here, but mine seems to use both of them, the lower one seems weaker. Tested with the camera flash and with flashlight on too.
As far as I know, most dual flash setups comes with a white led and a yellow one, so you can get a smoother white balance in your pics. Maybe the camera AI choose how much of each one is used depending on the light of the environment you're taking pictures, just a guess.
When looking with the naked eye, it is difficult to distinguish whether both LEDs are lit. Try cover the flash with a piece of paper and try again. Or zoom in with other phone camera.
Yup, seems that only the top one is on, like yours! (my old Redmi struggled a little to take this picture)
I found a Xiaomi 12 disassembly video and there is only one LED! There is a some kind of sensor next to it.
So everything works as it should, thanks for your time
Hello All,
As the title says, the front scree is no longer working. When I perform a reboot, the screen does show some pink/blue static on the front screen, then turns black when the phone completes the reboot. The always on display sometimes comes on, but very rarely. It sounds like the phone is still working with the black screen (I can hear the unlock sound when I use my finger on the fingerprint reader). Is anyone else experiencing this? Any ideas on what I can do to troubleshoot this? I have tried a factory reset with no luck. Picture of screen during the reboot is attached (black lines on screen are a reflection).
Thanks.

Looks like hardware. Maybe a loose connector or failed hinge flex cable.
Looks like you need to call Sammy and see if you can get them to cover it, otherwise, you're going to end up paying for a replacement/new phone.
I had this problem with an older Sam phone. The screen would come on and then fade away. I found if I wound the brighness up full immediately after boot and before it faded away it would stay on. If I turned the brightness down it locked off again and had to be rebooted.
It's still OK as a spare phone provided I don't touch the brightness
Take it to a Samsung Service Center for repairs
