This page is for administrators who choose devices and for anyone setting up a phone or tablet for the Venzeo™ mobile app.
Checked on 2026-10-09 against mobile app version 384: operating system minimums, install sources and the checks behind certified reports.
Operating system
| Platform | The app runs on | Reports can be Certified on |
|---|---|---|
| Android phones and tablets | Android 7.0 or newer | Android 9 or newer, with Google Play services version 20.50.16 or newer |
| iPhone and iPad | iOS or iPadOS 16.6 or newer | iOS or iPadOS 16.6 or newer |
On Android 7 and 8, or with Google Play services older than 20.50.16, the app still works, but its reports get no certification label at all in the web interface.
Requirements for certified reports
Venzeo™ checks every report. A report is Certified only when the device that sent it meets all of these requirements. If one of them fails, the report shows Warning! instead:
| Requirement | Android | iPhone and iPad |
|---|---|---|
| App installed from | Google Play | App Store |
| Device security check | The device passes Google Play Integrity with strong integrity, and Google Play Protect reports no issues | Apple App Attest is available (it is not on simulators) |
| Device not modified | Not rooted, developer options turned off, not an emulator | Not jailbroken, not a simulator |
| Location | No app that fakes the GPS location | No app that fakes the GPS location |
| Device clock | Within 24 hours of the correct time | Within 24 hours of the correct time |
- Samsung Galaxy Store and other app stores: reports from these copies of the app are not certified, because the Google Play licence check passes only for apps installed from Google Play.
- Sideloaded copies (installed from a file): the app shows App Install Source and asks you to reinstall Venzeo™ from the official store.
- Wrong device clock: the app shows Inaccurate Time. If the clock is more than 24 hours off, reports show Warning!. Turn on automatic date and time to keep the clock correct.
- Huawei and other devices without Google Play services cannot pass the Google Play Integrity check, so their reports are not certified.
