Why I am not receiving notifications & incoming calls even though my app was in network?

Short answer: your phone is stopping EngVarta from running in the background. Many phones close apps to save battery, and then EngVarta can't ring when a call or notification arrives, even though you are online. This matters most for English Experts receiving calls and for learners waiting for a callback. Work through the checks below. They take about two minutes.

What should I check first on any Android phone?

1. Notifications are on. Settings > Apps > EngVarta > Notifications > turn on Allow notifications.
2. Calls can open on your screen. On Android 14 and newer: Settings > Apps > Special app access > Full screen notifications (called Full screen intents on some phones) > EngVarta > Allow. This lets the call screen appear even when your phone is locked.
3. Battery use is not restricted. Settings > Apps > EngVarta > Battery (or App battery usage) > Unrestricted. On older phones: Settings > Battery > Battery optimisation > All apps > EngVarta > Don't optimise.
4. EngVarta can show on top of other apps. Settings > Apps > Special app access > Display over other apps > EngVarta > Allow. The app also asks for this when it needs it.
5. Do Not Disturb isn't blocking calls. Turn it off from Quick Settings, or let EngVarta through it: Settings > Notifications (or Sound) > Do Not Disturb > Apps > add EngVarta.
6. Background data is allowed. Settings > Apps > EngVarta > Mobile data > turn on Background data, and make sure Data Saver isn't restricting EngVarta.

Menu names differ a little between phones. If you can't find an option, type its name into the search bar at the top of your phone's Settings.

What else should I change on my phone brand?

Some brands have extra battery savers on top of the checks above.

Xiaomi, Redmi and POCO

• Settings > Apps > Manage apps > EngVarta > turn on Autostart.
• On the same screen, open Battery saver and choose No restrictions.
• On the same screen, open Other permissions and allow Show on Lock screen and Display pop-up windows while running in the background.

Samsung

• Settings > Apps > EngVarta > Battery > Unrestricted.
• Settings > Battery (on some models: Device care > Battery) > Background usage limits. Make sure EngVarta is not in Sleeping apps or Deep sleeping apps, and add it to Never sleeping apps.

OnePlus, OPPO and realme

• Settings > Apps > App management > EngVarta > Battery usage. Turn on Allow background activity and Allow auto launch.
• Lock EngVarta in Recent apps so it isn't cleared: open Recent apps, tap the menu on the EngVarta card and choose Lock.

vivo and iQOO

• Settings > Battery > Background power consumption management > EngVarta > Allow.
• Turn on Autostart for EngVarta: Settings > Apps > Autostart, or i Manager > App manager > Autostart manager on older phones.

Huawei and Honor

• Settings > Battery > App launch > EngVarta. Switch off Manage automatically, then turn on Auto-launch, Secondary launch and Run in background.

Google Pixel, Motorola, Nokia and other phones

The first checks are usually enough. Keep notifications on and set EngVarta's battery use to Unrestricted.

I use an iPhone. What should I check?

1. Settings > EngVarta > Notifications > turn on Allow Notifications.
2. Make sure a Focus mode or Do Not Disturb isn't silencing EngVarta. Turn it off in Control Centre, or go to Settings > Focus > the Focus you use > Apps and add EngVarta to the allowed apps.
3. Settings > EngVarta > make sure Mobile Data is on if you use EngVarta away from Wi-Fi.

Still not getting calls?

• Update EngVarta to the latest version from Google Play or the App Store.
• Stay signed in. If you restart your phone, open EngVarta once afterwards.
• Check your connection. Calls need working mobile data or Wi-Fi.
• If it still doesn't work, tap HELP in the app to contact us, and tell us your phone model.
