Phone temperature sensor not working - Charging slow - How to fix?

Recently, something has happened to my phone's temperature sensor. It's showing ridiculously high values for the temperature (over 100 degrees), even though it's very cold. This has caused my phone to refuse fast charging, and it charges very, very slowly. (~7 hours to charge)
Is there anyway I could turn off a sensor or fake its value so that my phone charging returns to normal?
Or is there anyway to force the phone to ignore the thermal limits during charging? (I know it's dangerous but I have no choice)
Deleting the thermal engine file doesn't fix the issue.

Calibrate accelerometer?
I'm developing an app that is supposed to measure vertical accelerations, and in the process I've discovered that the accelerometer seems to be uncalibrated. When the phone is lying perfectly horizontal, the Z axis acceleration should be 9.81, but it is about 8.81 (X and Y being roughly 0.0). I can...
I'm developing an app that is supposed to measure vertical accelerations, and in the process I've discovered that the accelerometer seems to be uncalibrated. When the phone is lying perfectly horizontal, the Z axis acceleration should be 9.81, but it is about 8.81 (X and Y being roughly 0.0).
I can of course offset the error from within the app by letting the user "calibrate" the app while the phone is lying still. But it seems odd that there is no method within Android to do this - sometimes Google Maps prompts me to calibrate the compass by moving the phone in figure eights - but I have not seen any way to calibrate other sensors... is it possible?
A further problem is that if I turn the phone so the top is facing straight up (up/down in line with the direction of gravity), the offset of the axis' are different from what is expected, and different from the offsets I get when the screen is facing up. This all seems to indicate that the accelerometer is not as accurate as one might think, and when adding rotation to the mix the results get even more skewed...

How to disable turning screen off based on proximity / light sensor?
Problem: Android 13.0.0 turns screen off based on proximity / light sensor. How to disable turning screen off based on proximity / light sensor? I've already tried to find a dedicated setting by searching for "proximity", "light", "sensor", but couldn't find a dedicated setting.

Increase accelerometer sensitivity
I have a Samsung Galaxy S23 Ultra. I wish to increase the sensitivity of my accelerometer. I play a combat game with jets and cannot switch to a joystick as I have played too long with an accelerometer, tilting the phones to move left and right. It is like being able to move quicker left and right.

Prevent accidental touch while speaking on GrapheneOS (AOSP)
I've got a Google Pixel 8 Pro running GrapheneOS. When I'm on the phone talking to somebody and hold the phone to my ear, it very often accidentally registers taps.

I've got a Google Pixel 8 Pro running GrapheneOS. When I'm on the phone talking to somebody and hold the phone to my ear, it very often accidentally registers taps. This e.g. leads to activation of the flashlight or Bluetooth by the slide-down menu. Locking the screen after answering the call does not help, probably because the slide-down menu is accessible anyway. I cannot find any setting to prevent this. Does anyone have the same issue or any idea of how to fix this?
I used the app Sensors Toolbox to check whether the proximity sensor works as it should. And it does. However, it only detects small distances at the top of the phone (where the ear should be during the call, which is not always the case). If the phone detects a small distance to the skin during the call, the screen is deactivated, but is activated if the phone slips a little from that position. Is this normal?

How is the Body Sensor Permission utilized by the apps? \
I'm aware that it uses a hall and proximity sensor to detect human presence. I want to know how exactly it detects specific people. I'm talking of the smart lock: On-Body Detection. It used to be fairly inaccurate but the hall and proximity sensors cannot distinguish between bodies (i think, correct me if I'm wrong) \
So is there something I'm missing?
Can it read my ("vital signs") respiration rate, heart rate or body temperature (as it says on the screenshot)? I'm particularly interested because Google has it and Google has made it just for itself!? I've not seen any app request for this permission
!
. !
Googling shows body sensor is used to detect physical activities but it's not. The dedicated physical activity sensor is used for that.

Can Doogee Y9 Plus run AR apps?
I have recently bought a Doogee Y9 Plus. As I found out, the phone does not have a compass or gyroscope. I wanted to ask if the phone could still use AR apps. The phone isn't rooted, but I might even do it.

How can I disable my phone's magnetic field sensor or stop Android from using its data for `Sensor.TYPE_ROTATION_VECTOR`?
I've noticed that OsmAND's compass is much more accurate when forcing it to use the orientation sensor (`Sensor.TYPE_ORIENTATION`) instead of the magnetic field sensor (`Sensor.TYPE_MAGNETIC_FIELD`).

I've noticed that OsmAND's compass is much more accurate when forcing it to use the orientation sensor (
Sensor.TYPE_ORIENTATION) instead of the magnetic field sensor (Sensor.TYPE_MAGNETIC_FIELD).
Other (more modern) apps use Sensor.TYPE_ROTATION_VECTOR however and according to [the Android documentation](https://source.android.com/docs/core/interaction/sensors/sensor-types#rotation_vector) , this combines data from the orientation sensors aswell as the magnetic field sensor.
How can I disable the magnetic field sensor entirely or prevent Android from using its data for Sensor.TYPE_ROTATION_VECTOR?

How do I get the temperature of my phone via ADB?
At work, I run lots of automated software testing on Android phones. They stay permanently plugged into a development machine, and are given jobs to run via ADB. I'd very much like to be able to monitor their temperatures, and doing so via ADB would be the easy way.

I want to make a data science workshop. I know that some apps in smartphones in general have the ability to get tracking data, for ad, tracking and surveillance purposes.
I want to make people more conscious of this, by letting the user get this data and work with it him/herself.
Are there any more direct ways for accessing data of sensors in a given android phone (in a transparent, non-invasive way), export it to a file in the phone so that it is possible to be read by a script for data science purposes?
Thanks in advance.

If any of you know about the placement of specific sensors (doesn't have to be very precise) that would help me.

When I touch the fingerprint sensor while I watch YouTube in the app it activates the controls on YouTube, like I was tapping the screen. Somehow the YouTube app and maybe other apps listen to the event of the fingerprint sensor and reacts to it. This is very annoying to me since the fingerprint sensor is in an easy to reach place so it happens often. This is reproducible on different phones and android versions. Is there a way to disable this behavior somehow?

* [How does Android obtain battery temperature](https://android.stackexchange.com/questions/29405/how-does-android-obtain-battery-temperature)
Yet, I'm curious if there's a method for deriving ambient temperature from battery data. A [quick search](http://patft.uspto.gov/netahtml/PTO/search-bool.html) at U.S. Patents and Trademarks' Office revealed no such patents (yet).

Do you not have to worry about leaving your fingerprint randomly on the sensor which could waste battery?

I'm looking for a way to set the x, y, and z values for the accelerometer sensor on an android emulator for tests using espresso. My test requires that the device be positioned in a specific way and I am aware that the android emulator has extended controls to modify the rotation and movement of the virtual sensors. However, I am looking for a way to do this automatically without needing to use the extended controls or physically moving an actual device.
I have successfully modified the virtual sensors through the emulator console when connecting to the emulator via telnet; however, I haven't found a way to achieve this programmatically. To do this via telnet, I first needed to enter an authentication token, then, I used the following console command
set acceleration x:y:zshell dumpsys battery set level
