When switching phones, almost everyone will reinstall WhatsApp on their new device. Even if you have entered the same phone number or account, the WhatsApp messages on the old phone will disappear unless you perform a data backup recovery."

The synchronization issue between mobile devices and cloud services such as Google Drive and iCloud can also cause WhatsApp messages to disappear when the data backup recovery process is carried out. Typically, phones automatically back up to the cloud according to routine settings. However, if there are problems with the internet connection or storage capacity is full, the backup process may not run smoothly.

"Log out of your Google account and log back in. Turn off and turn on Wi-Fi again, or use mobile data. Force stop the WhatsApp app and reopen it. If storage capacity is limited, reduce the size of the data being backed up. Make sure the device's battery is not nearly dead. If using dual SIM, turn off the unused SIM. Check for updates in the Play Store as WhatsApp may need to be updated."

Sure! Here's the translation with the HTML tags preserved: "After the backup is complete, you can restore your chat history at any time with the following steps: Open the Google Drive app and sign in to your Google account. Tap Menu > Backups. Check if there is any recent WhatsApp backup data. Delete WhatsApp from your device, then reinstall the app. Tap the "Restore" option. This step also applies when you change devices."

Here is the translated text with HTML tags preserved: "If you want to turn off this feature for specific chats or groups, do the following: Open the desired chat or group. Tap the contact or group name. Tap "Disappearing message". Select "Off". Those are some of the reasons why WhatsApp chats disappear on their own and how to address them, which can help you solve this issue. Good luck trying!"
