Then this is the app for you. With this app you can get a good idea of cell and WiFi signal strength and find out which corners of your office or home have the best reception.Very few phones do not meet the signal reporting standard, especially regarding dual SIM. Some phones also do not report the network cells required for this application. If the signal strength does not update, it is a sure sign of a broken ROM. This is a known issue, not an issue with the app.
