Hi max_r. First I want to thank you for your post, I think it helped a lot, but I have a problem If you or anybody else can help me.
I did everything step by step how you mentioned.
My phone is Ngm Dynamic Maxi, not so popular so it's kind of hard to find help.
1. The phone is rooted.
2. I installed Android Sensor Box from Google Play.
3. Opened ASB, tapped on Proximity sensor, then on the down-left cornered button ad saw the name of the driver, like in the next screenshot:
The name is:
and the vendor is
4. Now I instaled, opened and granted super usor acces to Hardware Disabler, tapped on settings, sellected directory
to scan:
5. Then I tapped on Rescan for drivers and clicked Click me to confirm:
6.A new very long list of drivers loaded but I coudn't find my proximity sensor driver, I shearched for it many times:
Here is the list of all my device's drivers:

The thing is this isn't the only driver that I can't find in the list, none of my drivers from ASB. I can't find none of them and not even the vendors, most of them have Bosch vendor like in the next images:
I would really apreciate if somebody cand help me, my phone fell from my poket and cracked the screen exactlly where the proximity sensor is, And when I'm in call the screen goes black and I have not control over the phone, can't look in to my contacts etc during the call. I would like to manually lock it while in the call to save battery life, but i nthe same time be able to do everything else when I unlock it.
I hope for a good response, thank you again and have a nice day.
