WhatsApp for Xiaomi Mi Mix 2s

MIUI's Gallery sometimes hides the WhatsApp Images folder because the media-scanning index gets out of sync, or because WhatsApp's media visibility is turned off. First, in WhatsApp go to Settings > Chats and enable 'Media visibility'. Next, confirm WhatsApp has storage permission under Settings > Apps > Manage apps > WhatsApp > App permissions > Storage. If images still don't appear, check that no '.nomedia' file exists in the WhatsApp Media folders (a file manager can show it), then reboot the phone so MIUI re-scans the folder.

MIUI's aggressive battery management is the usual cause, since it suspends WhatsApp in the background to save power. Go to Settings > Apps > Manage apps > WhatsApp > Battery saver and set it to 'No restrictions'. Then enable Autostart for WhatsApp under Settings > Apps > Permissions > Autostart. Finally, open the Recents screen, find the WhatsApp card, and tap-and-hold (or pull down on) the card to lock it so MIUI won't clear it from memory. See how others solved this on Reddit

Picture messaging fails when mobile data is off or the carrier's MMS APN settings are missing, since MMS needs a mobile-data connection even when you're on Wi-Fi. Turn on mobile data, then go to Settings > SIM cards & mobile networks > your SIM > Access Point Names and confirm an MMS APN is configured (your carrier can supply the MMSC and proxy values). Grant the Messaging app its permissions under Settings > Apps > Manage apps, and make sure auto-retrieve for MMS is enabled in the Messaging app's own settings. See how others solved this on Reddit

Yes. MIUI has a built-in 'Dual apps' feature, so you don't need a third-party cloner. Open Settings > Apps > Dual apps, toggle on WhatsApp, and a second cloned WhatsApp icon appears that you can register with a different number. Alternatively, Settings > Apps > Second space creates a fully separate profile with its own apps and storage, letting you keep a second, completely isolated WhatsApp install.

WhatsApp itself works fine because it runs over mobile data or Wi-Fi, but the Mi Mix 2s lacks the CDMA bands Verizon traditionally uses, so it's best paired with a GSM carrier such as AT&T, T-Mobile, or their MVNOs. Insert a compatible SIM, then set the correct data APN under Settings > SIM cards & mobile networks > Access Point Names so mobile data connects. Once data or Wi-Fi is up, verify your number in WhatsApp as normal. See how others solved this on Reddit

MIUI includes system ad services you can largely disable. Open the Security app (or Settings) and turn off recommendations within each system app, and disable personalized ad recommendations under Settings > Passwords & security > Authorization & revocation by turning off 'msa' (the MIUI System Ads component). To keep alerts clean, also turn off unwanted notification categories per app under Settings > Notifications & Control center > App notifications. See how others solved this on Reddit
