Installation

Downloading the GCG App

The GCG App is only available for users from authorized institutions. The current list of partner institutions is available here. GCG can be downloaded from the Google Play Store or official IISc link provided by your institution. Do not download the App from any other third-party sources since it may not be authentic. You will need an invitation code to activate the GCG App. It will not work without a valid invite code. This too will be provided directly by your institution as part of the initial welcome email.

Device Pre-requisites

The GCG App is initially available for Android devices. An iOS ad hoc version is available for testing by invitation. Any Android smart phone running version 6.0 (Marshmallow) or later is supported. The phone should also support Bluetooth Low Energy (BLE), which most phones purchased in the last 4 years should have.

Installation for Android

  1. From your smart phone, download the App from the Google Play Store.
  2. You will be prompted to Install the App, and that it does not require any special access. Select Install.
  3. You will get an App Installed confirmation. You can then Open the App.
  4. Please go through the installation screens. Read all the instructions carefully.
  5. Please read the Informed Consent carefully. This describes the data that is collected and how it is used.
  6. You will be prompted to allow access to the device's location. Select Allow or Allow Always. (NOTE: In Android, access Bluetooth is termed as location permission. We do not collect your GPS location unless you explicitly allow it from the App later. For more details, refer the FAQ.)
  7. You may optionally enter your Phone Number and get it OTP verified. This will allow you to reinstall the App later without requiring a new Invitation Code.
  8. Enter your Invitation Code, read the Terms and Conditions of using the App and click on Activate.
  9. If the Invitation Code was valid, you will be displayed your PIN number. Keep this PIN safe and do not share it with anyone.
    • NOTE: If you have provided your phone number, this PIN can be used along with the phone number for reinstalling the App later and you will retain your earlier Unique ID linked to your prior data. If you have NOT provided your phone number, you will need a fresh invitation code to re-install the App and all your past data will be lost. You can always update your phone number under Settings to allow re-installation.
  10. Click Done. You are ready to use the GCG App!
  11. Make sure to keep Bluetooth and GPS on all the time. This is necessary for contact tracing to work. See the FAQ for more details.

Reliable Contact Trace Data Collection

Is data being collected properly?

Installing the App is the first step toward digital contact tracing for COVID. Given the diversity of phone brands and OS modifications by these vendors, not all Android phones allow GCG App to work properly and perform Bluetooth contact tracing. There are two ways you can find out if contact tracing is happening.
  1. Check if the progress bar increases during the entire day and is close to 100% at the end of the day. This means your scans and advertising is happening properly.
  2. Click on the progress bar or Plots icon at the top of the App to see the scans for each hour in the past 24 hours. If all bars are green, then your scans and advertising is happening properly.
  3. Watch out for notification alerts in the GCG App that state that you have not collected enough data to show any scores, or inform you that contact data collection is not happening properly from your phone with a link to this GCG support website.

Common solutions

Enabling Bluetooth and GPS

Say your GCG scan progress bar is not moving at all or moving slowly through the entire day. The obvious thing to check is if you have Bluetooth and GPS enabled all the time. If either of them are not turned on, contact data will not be collected. You will see a "Scanning Stopped" the notification panel of your phone, and a banner "Please enable GPS/Bluetooth" at the bottom of the App. If so, you should enable Bluetooth and GPS. Here is a video on how you can do it.

In rare cases, if you denied permission for GCG to use Bluetooth when the App prompted you, and you selected "Don't ask again", just keeping Bluetooth on will not be sufficient. You need to go to Android Settings, you App Manager, select GoCoronaGo, and under permissions, enable Location permission.

Allowing the GCG App to run in the Background

The GCG App keeps running in the background and performs contact tracing, even when you're not using the App. But some Android phone brands kill Apps that run in the background after a short period of closing the App. You may need to go under Android Settings and look for options under App Manager settings to allow the GoCoronaGo App to run in the background. Videos on how to do this for some common phone brands are shown below.

Allowing "High Power Consuming" Apps to run

The GCG App keeps running in the background and performs contact tracing using Bluetooth. This consumes a small amount of power, less than 10% in a hole day. Some Android phone brands end up marking the GCG App as a "high power consuming" app and kill it to optimize power. You may need to go under Android Settings and look for options to allow the GoCoronaGo App to keep running, even if it consumes power in the background. This may be under the App Manager settings or Battery settings. Videos on how to do this for some common phone brands are shown below.

Enabling Auto-start of GCG App

When you reboot the phone, the GCG App tries to start automatically. But some Android phone brands do not allow the App to automatically start unless the user manually enables it. You may need to go under Android Settings and look for "autostart" options under App Manager settings to allow the GoCoronaGo App to start automatically when the phone restarts. Videos on how to do this for some common phone brands are shown below.

Locking the GCG App in the App Switcher

Some users go to the Android task switcher or recent tasks list and clear out all Apps that are running. In some Android phone brands, this can kill the GCG App running in the background. In such cases, you may need to "lock" the GCG App in the task switcher so that it does not get killed if you clear other recent Apps. Videos on how to do this for some common phone brands are shown below.

Having Internet Connectivity

The GCG App does not need an Internet connection all the time. However, it needs to connect to the Internet a few times a day to allow the contact trace data to be uploaded. This allows proximity and other forms of contact scores to be updated, and reported back to you and others in the contact network every day. This consumes just a few MB of data each day. So try to be connected to the Internet for at least some time every day.

Brand-specific solutions

We have additional videos on how to solve the common scanning problems for some of the Android phone brands. More will be added over time. If your brand phone is not listed, you may be able to find a solution at https://dontkillmyapp.com/ or your phone manufacturer's website by searching for "allow background apps" or "app power consumption".
