WhatsApp for LG Q6

Over time WhatsApp's databases and downloaded media pile up and can swell to several gigabytes on the Q6's modest storage. Open WhatsApp, tap the three-dot menu, go to Settings, Storage and data, Manage storage, and delete large items and forwarded media. Then in Android Settings, Apps, WhatsApp, Storage you can clear the cache without losing chats. Turning off auto-download under WhatsApp Settings, Storage and data prevents the folder from re-bloating. See how others solved this on Reddit

This block usually appears after several failed verification attempts or when WhatsApp suspects unusual sign-in activity, and it often clears on its own after waiting a few hours. Make sure your Q6 has the latest WhatsApp from the Play Store, a stable connection, and the correct phone number, then request the SMS code again rather than retrying repeatedly. If it persists past a day, request the code by phone call or contact WhatsApp support from the verification screen. See how others solved this on Reddit

Android's battery optimization on the Q6 puts WhatsApp to sleep, so incoming-call alerts arrive late or not at all. Go to Settings, Apps, WhatsApp, Battery and set it to Unrestricted (or remove it from battery saving), then in WhatsApp, Settings, Notifications make sure call notifications and 'Use high priority notifications' are enabled. Also confirm Do Not Disturb is off and that WhatsApp has permission to display over other apps. See how others solved this on Reddit

This happens when WhatsApp's 'Media visibility' is off or the Q6 hasn't been granted full photo permission, so saved images stay hidden from the Gallery app. In WhatsApp go to Settings, Chats and turn on Media visibility, then in Settings, Apps, WhatsApp, Permissions allow access to Photos and media. If images still don't appear, restart the phone so the gallery re-scans the WhatsApp Media folder. See how others solved this on Reddit

WhatsApp validates its security certificates against your clock, so a wrong date or time zone triggers this error and blocks connection. On the Q6 go to Settings, General, Date & time and turn on 'Set automatically' (automatic date and time) and 'Automatic time zone' so it syncs from the network. After correcting it, force-close and reopen WhatsApp. See how others solved this on Reddit

When data is fine but messages stick with a single clock icon, the issue is usually WhatsApp's background data or a stale connection rather than your network. In Settings, Apps, WhatsApp, Mobile data and Wi-Fi, enable Background data and Unrestricted data usage, then clear the app cache via Settings, Apps, WhatsApp, Storage. If it continues, update WhatsApp from the Play Store or reboot the Q6 to refresh its connection to the servers. See how others solved this on Reddit
