Phone signal

Check how good your cell phone signal is at home or at work, upstairs or downstairs.

Is the signal low or are you having a lot of cell handovers (handoffs) due to a poor signal; check if you should consider a different cell phone operator, or make your important calls from a different room.

Phone Signal allows you to check cell phone signal quality in detail (signal strength, handovers, radio type changes) over time and get cell network information.

Monitor signal

Provides an overview of SIM, network and signal strength (up to 1 minute). The signal graph is color coded to represent strength (green, yellow, red). Cell handovers (handoffs) are shown with vertical orange bars. Cell radio technology changes (e.g. LTE 4G to UMTS 3G) are shown with blue vertical bars.

Notes
Please note that not all phones correctly report signal strength. If you have a problem with Phone Signal, please report it as a bug and I will investigate. Thanks.
