Tester instructions

Testing the 2Greet app

This page is intended for hired testers of the 2Greet app.

Please do not install this special version of the app and don’t attempt to follow these procedures unless you were enrolled in the testers program.

Thank you!


In order to run the tests you need a phone running Android 6.0 (Marshmallow, API level 23) or higher. You will not be able to install the app on older versions.

Your phone needs to support the Google apps. Phones from vendors that don’t install the Google apps will not work.

We prefer that your phone is updated to the most recent supported version.

You need to have a 4G LTE subscription and also a WiFi connection. The kind of WiFi that requires a secondary authentication (like found in hotels) is not adequate.

The tests you are going to run will use up to 2 MB (MegaBytes) of LTE plus WiFi data. See the description of each test for details.


2Greet will ask for two permissions to run:
Phone (since it’s a telephony app)
Microphone (since it needs to transmit your voice)

Both permissions should be granted or the app can’t run.

User data usage and privacy

For testing we will need your real phone number in order to send you the Authentication SMS needed by the app. We will delete this number during the processing of test results and we will not share it with any other entity.

We also collect the device type as exposed by the Android system to correlate with the test results. We keep this information only to identify app issues on specific device types.

Please see our Tester Privacy Policy for all the details.

Uninstall and cleanup

Getting rid of 2Greet may be a bit tricky since some telephony settings are kept by Android outside the app’s control.

To remove all traces of the app after you finished the tests:
– Uninstall 2Greet
– Reboot the phone

These steps will make sure your calls will be restored to normal.


Testing and reporting

Please follow the steps below to execute the tests.

After you finish or as you run each step please fill the reporting form to let us know the results.
