farkasditke73 You can't. On Android 10 and up Google blocks all attempts to use Accessibility Services to be used to record conventional phone calls. VoIP and SIP calls can still be recorded, though. Some developers offer aids to circumvent this limitation. I tried Cube ACR and ACR Phone but neither of them worked.

farkasditke73 PMPO = Peak Maximum Power Output. It means it can output 7.8kW for a few milliseconds. 4*120W RMS (Root Mean Square) power output is a lot more realistic.

farkasditke73 Yes, it can, using the Pythagorean functions. You must target the laser on the highest point of the cargo and it will measure its height from the device, i.e. NOT from the ground. Then you must add the distance of the device from the ground, which you only have to measure once and note it.

farkasditke73 The same here, S5 Pro. No security updates, no new Android versions.

farkasditke73 Which one has the constant current constant voltage driver?

farkasditke73 Strictly speaking the emitted light is not laser so there's no need for a laser marking. An internal laser source is used to excite the phosphor: LEP, Laser Excited Phosphor. If it were laser the light wouldn't be white.

farkasditke73 Mine is micro USB.

farkasditke73 Impossible. It would require two hundred and fifty amperes on twelve volts. The resistance of the heating element should be forty-eight milliohms.
