WhatsApp for Xiaomi Mi Mix 2

MIUI's aggressive battery management can block WhatsApp's media scanner, so downloaded photos never get indexed by the Gallery. Go to Settings > Apps > Manage apps > WhatsApp, set Battery saver to No restrictions, and enable Autostart, then make sure WhatsApp > Settings > Chats > Media visibility is turned on. If old images are still missing, check that a .nomedia file isn't present in Internal storage/WhatsApp/Media/WhatsApp Images, then reboot the phone to force a media re-scan.

MIUI freezes background apps to save battery, which holds WhatsApp notifications until you open the app. Under Settings > Apps > Manage apps > WhatsApp, enable Autostart and set Battery saver to No restrictions. Then open the recent-apps screen, swipe down on the WhatsApp card to lock it so it isn't cleared from memory. Disabling Settings > Battery saver also stops the system from suspending the app overnight. See how others solved this on Reddit

Recording problems are usually a missing microphone permission: grant it under Settings > Apps > Manage apps > WhatsApp > Permissions > Microphone (do the same for Telegram). If playback goes silent or cuts out when the phone is near your face, that's the proximity sensor switching audio to the earpiece, so play messages with the screen facing you or clean the sensor area at the top of the screen. If recording still fails, clear the app cache via Settings > Apps > Manage apps > WhatsApp > Clear data > Clear cache and re-grant the microphone. See how others solved this on Reddit

Yes, MIUI offers two built-in ways. For a quick cloned account use Settings > Apps > Dual apps and toggle WhatsApp on to get a second copy that runs alongside the first. For a fully separate profile with its own contacts and storage, use Settings > Special features > Second space, which creates an isolated environment where you can install another WhatsApp. See how others solved this on Reddit

The reliable route is WhatsApp's own backup rather than Mi Mover, which often skips app-specific message data. On your old phone open WhatsApp > Settings > Chats > Chat backup and back up to Google Drive (use the same Google account on both phones), then install WhatsApp on the Mi Mix 2 and restore when prompted during first-time setup. Mi Mover can copy the app and local media, but always run the Google Drive backup first so your chat history survives. See how others solved this on Reddit

MIUI system apps inject ads that can crowd your notification shade and slow the phone down. Disable the ad framework under Settings > Passwords & security > Authorization & revocation by turning off MSA, then open the Security, File Manager, and Get Apps (Mi Store) apps and toggle off Receive recommendations in each app's settings. This leaves WhatsApp and other apps untouched but removes the system-level ad noise the update introduced. See how others solved this on Reddit
