Apple iPhone
Update November 7th 2017 Releases after 10.3.3 will not allow for toggling between the signal bars and the dB signal reading.
For current models using 11.1 iOS please do the following:
• Key in *3001#12345#*
• Tap : Serving Cell Measurements
• Scroll down to: Measured RSRP
• Add +20 dBm to the resulting number (example -102 shown
would be -82 dBm ... tModes.pdf

Yes, but it is not persistent and must be accessed each time needed, whereas before the downgrade this info was always displayed instead of the useless bars.
