Displays and Logs Cellular, Wi-Fi, Bluetooth, and GNSS Network Survey Details
About this app
The Network Survey app enables logging cellular, Wi-Fi, Bluetooth, and/or GNSS information to a log file (GeoPackage or CSV format). For cellular records it supports logging GSM, CDMA, UMTS, LTE, and NR records.
You might receive an alert from anti-malware software indicating that Network Survey sends SMS messages in private manner to deceive users. This is NOT the case. SMS permission is necessary for some of the logging that is done. Just to be clear though, Network Survey does not send any text messages, nor does it install anything. In fact, you can deny all the SMS permissions if you are not using the CDR (call detail record) logging feature. The SMS permissions are only requested the first time you turn on CDR logging. More information can be found in this GitHub Discussion: https://github.com/christianrowlands/android-network-survey/discussions/35
This app has the ability to access your device's location in the background. The background location permission is needed to start Network Survey at boot. You can deny this permission if you don't want to start Network Survey at phone boot. More information can be found in the App's privacy policy located at https://github.com/christianrowlands/android-network-survey/blob/master/privacy_policy.md
The cellular logging feature logs several details about the current serving cell, and then some basic information about the neighbor cells. This app won't log all 5 cellular protocols at once. Instead, it will only log information about the protocols that are current connected. If logging for one specific protocol is desired, then the phone must be locked to that protocol (try using *#*#4636#*#* from the dial pad).
The cellular survey records can be streamed to either a gRPC server or a MQTT broker. This is not on by default and a gRPC server or MQTT Broker needs to be setup for this feature to work.
See the NS Messaging GitHub Repo for more details on setting up a network survey gRPC server.
See for information on setting up a MQTT Broker.
A bonus feature of this app is its ability to create a Call Detail Record (CDR) file. If enabled, CDR events are logged to a CSV file.
The app also has a calculator that converts an LTE Cell ID to the corresponding eNodeB ID and Sector ID, and a calculator that converts an LTE PCI to the corresponding Primary Sync Sequence (PSS) and Secondary Sync Sequence (SSS).
I hope you enjoy this app as much as I have enjoyed writing it. If you have any feature requests please feel free to reach out by creating a GitHub issue at the link below.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.craxiom.networksurvey is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.55 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Network Survey first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Network Survey, and a listing is removed when the evidence for it stops holding up.

The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
