How Phono measures the signal strenght

Here some details, how phono calculates the signal percentage:

To determine the signal strength dBm is used, Android provides also ASU, which determine the speed at which the phone is able to update its position with the nearby antennas.
Phono uses an algorithm that tasform the asu in decibels to determine the actual signal strength on a linear scale. The bars in the statusbar instead take a range from -112dBm (low) to -60dBm (signal good) and for example when you above -87dBm it shows full, even if it should not. So the graph in the status bar is really approximate.
To further verify what I'm saying you can use: -> Menu -> Settings -> Phone info -> Network (second item) -> Signal strength (second item)
You'll find the specified dBm and ASU, compare them with those of Phono and see which are the same (but do not change location while doing it).

Finally to say the signal quality is a provider / net problem and not an issue of phono!

Hope this makes the situation a little bit clear to the users. ;) If not, feel free to contact us.
