Mobile Cell Phone Test Mode
Signal strength is a number ranging from roughly -50 to -105. Some cell phones
may show as a positive number. -50 (roughly full signal) is better than -105 (roughly no signal).
Approximately -95dB is the bare minimal signal strength to make a phone call.
- -90 - ~2 bars
- -85 - ~3 bars
- -80 - ~4 bars
- -75 - ~Full Signal
- The closer to zero the value is; the better signal strength is.
