r/VivoX300Ultra

Dears, I noticed how aggressive is the doze management with the emails on my Vivo X300 Ultra (Global version). If you are struggling with that too, let me show you how to fix it!

Symptoms:

• WhatsApp notifications worked fine
• Gmail and Outlook only synced when opening the app
• No instant email notifications with screen off

Fix (NO ROOT):

1. Enable Developer Options + USB Debugging

2. Install Minimal ADB & Fastboot or Android Platform Tools

3. Connect phone to PC

4. Run:

   adb shell dumpsys deviceidle disable adb shell settings put global device_idle_constants inactive_to=2592000000 adb reboot

After reboot:

• Gmail push notifications work normally
• Outlook push works too
• Instant email notifications with screen off

Cause was Vivo’s aggressive Device Idle / Doze management suspending email sync in standby. Greetings from Italy

Took the shiny new toy (with 200mm teleconverter) out for a spin yesterday, very happy for the shots!
