I have this "problem" as in the title. The signal dBm reading is inaccurate and certain app needs more accurate readings. When there are four bars, the dBm is -89dBm, and three it's -93dBm and one -101dBm and zero -111dBm.
The signal strength reading is dependent from bars.
My app needs more accurate readings between the bars, for example -90dBm and so on. How to improve it?
Hope you understood, it's a very little but annoying issue.
