WhatsApp for Vivo V27

Floating banners are controlled by Funtouch OS, not WhatsApp. Go to Settings > Notification & status bar > Manage notifications > WhatsApp and turn on 'Allow notifications', then enable the 'Banner'/'Floating notification' style and 'Lock screen notifications'. Next, in WhatsApp tap Settings > Notifications and turn on 'Use high priority notifications' for both messages and groups. Finally, stop the OS from throttling the app: Settings > Battery > Background power consumption management, find WhatsApp and set it to 'Allow background activity' so notifications can wake the screen.

First confirm the permission: Settings > Apps > App manager > WhatsApp > Permissions > Microphone and set it to 'Allow' (Funtouch sometimes leaves it on 'Ask every time'). If the mic still cuts out, clear WhatsApp's cache (same app screen > Storage > Clear cache) and make sure no other app is holding the mic — close recorders, call recorders or the voice assistant from the recents tray. Then test the hardware in the stock Recorder or Phone app; if it's bad everywhere, check that the bottom mic hole near the USB-C port isn't blocked by a case or dirt.

This is usually Funtouch OS power management killing WhatsApp in the background. Go to Settings > Battery > Background power consumption management, find WhatsApp and choose 'Allow background activity', then turn on Auto-start for WhatsApp under Settings > Apps > Auto-start (or 'More settings' > Auto-start manager). Also grant WhatsApp 'Display over other apps' (Settings > Apps > Special app access > Display over other apps) so the full-screen incoming-call UI can appear, and enable 'Lock screen notifications' for WhatsApp in the notification settings.

On Android 13+ WhatsApp needs full media access. Go to Settings > Apps > App manager > WhatsApp > Permissions > Photos and videos and choose 'Allow all' rather than 'Select photos' or 'Ask every time'. If folders still don't show, open the stock Albums/Files app once so the system media scanner re-indexes storage, and confirm the missing folders aren't marked hidden or stored on a path (like a hidden '.nomedia' folder) that the gallery won't index.

That blinking is the Funtouch OS notification LED, set per app. Go to Settings > Notification & status bar > Manage notifications > WhatsApp (or Messenger) and turn off the 'Light' / 'LED notification' toggle. If you'd rather kill it for everything, look under Settings > Notification & status bar for a global 'Notification light' / 'Pulse light' switch. You can leave sound and banners on, so messages still alert you without the constant flashing. See how others solved this on Reddit

iPhone-to-Android WhatsApp transfer uses WhatsApp's official cable-based tool. During the Vivo's initial setup, run the 'Move to Android' / Google data-transfer flow with both phones connected by a USB cable, then in WhatsApp tap Settings > Chats > 'Move chats to Android' and follow the on-screen QR-code steps. An iCloud backup alone won't restore on Android, so don't delete WhatsApp from the iPhone until it finishes. Afterward, verify the same phone number and set up Google Drive backups under WhatsApp > Settings > Chats > Chat backup. See how others solved this on Reddit
