DHD Proximity Sensor Recalibrator Due to many DHD's being incorrectly factory calibrated with regards to the proximity sensor, this little app was written to allow one to change the calibration on-the-fly and persist it over reboots.
This app is specifically for those experience issues with the proximity sensor.
Well known symptoms include the following:
- Screen fails to turn off when holding to face on a call
- Screen does turn off when holding to face on a call, but fails to come back on, requiring taking out the battery
These problems are common in custom kernels/ROM's. HTC has addressed this issue however in their kernels from 1.32 onwards, but have failed to release Linux kernel source code for any new versions (latest source is pre-1.32).
1. Install app.
2. Run app.
3. Press the toggle button to start monitoring.
4. Move your finger over the proximity sensor (the little LED next to the front facing speaker).
5. Adjust the High and Low threshold values to your liking.
For those whose screen does not turn off, it probably means the factory values are set too high.
For those whose screen does not turn back on, it probably means the factory values are set too low.
The setting will be saved, and will be applied every time you reboot your phone. No need to go through any of the steps unless you want to change the calibration. When the settings are applied at boot time, you will get a toasty indicating the calibration value applied.
If for whatever reason you find the application does not work, or you do not want it anymore, just uninstall the app, and reboot. Your original factory settings will be in effect again. This application does not modify your system and does not require root rights.
