Rx Monitor

The description of Rx Monitor

Site Editorial Commentary：Monitor 2G/3G/4G/5G mobile radio signal reception from cell sites.

Rx Monitor provides a real-time display of mobile network information that your phone uses to communicate. It includes basic network details, call and data statuses, and received radio signal information from cell sites. Tapping on any displayed information will bring up a helpful dialog explaining various terms and acronyms.

Cell information is compatible with all technologies: GSM, UMTS, LTE, and NR. Displaying cell frequencies requires Android 7.0 or newer, while NR functionality requires Android 10 or later.

For newer Android versions, location services must be enabled before cell data can be displayed.

A chart for signal level is also available, offering zoom (pinch-zoom) and scroll (swipe diagonally) functionalities. The Events tab shows changes to your phone's status that might be of interest. The map tab overlays the network information on a map (gps must be enabled).

With neighbor cell information, you can use Rx Monitor in different scenarios to understand your mobile coverage:

- Determine the quality of your LTE coverage. See if you are in an area with a strong LTE signal from one cell or near the edge, where signals from multiple cells have similar strength. If your current cell has issues, identify other cells with good coverage as a backup.

- If you only have 3G coverage, check the signal level of LTE. Walk around with the app to find where LTE coverage ends and the service switches to 3G.

- On Android 7.0 and newer, check the signal level of LTE on different bands. Identify the signal level of your preferred band (e.g., one with large bandwidth, 4x4 MIMO, etc.) and see which band your phone is using.

For phones with dual SIM cards, operator and service statuses are displayed for each SIM when registered (i.e., connected). Registered and neighbor cells are combined for both SIMs on older Android versions. From Android 10, cells from different SIM cards can be distinguished.

IMPORTANT: This app might not function correctly or provide accurate values on certain phone brands or models due to the manufacturer's specific Android software implementation.

The app offers an in-app purchase for the Pro version, unlocking these features, managed through the option menu in the upper right corner:

1. Ad removal.

2. Log file saving (THIS FEATURE MAY BE REMOVED IN THE FUTURE). Log files are created in the app's private folder. You can move logs from previous sessions to a public folder via the option menu for easier management with file manager apps. Log files, in both private and public folders, can be opened using the Files tab. (This tab is hidden if no log files exist.) Log files are in sqlite database format (RxMon--.db). In case of a log writing error, a .db-journal file is also created, which helps repair the database when the .db file is opened.

Background monitoring IS NOT INCLUDED, as this feature has not been functional for some time.
