For reasons that you still cannot explain, WhatsApp no longer works well and you would like to try to reinstall the application? You just formatted your smartphone and you don't know how reinstall WhatsApp without losing your old conversations? Don't panic. WhatsApp includes an automatic backup system that stores all conversations on the cloud (on Google Drive if you are using an Android terminal or on iCloud if you are using an iPhone) and allows you to restore them to any device connected to the same phone number and the same account Google / Apple of the backup source phone. The only exception is represented by Windows Phone, where in any case it is possible to resort to backups of chats saved locally by the application.
I would say not to waste any more time. Come on, give me five minutes of your time and find out how to restore the installation of WhatsApp on Android, iPhone and Windows Phone thanks to the instructions I am about to give you. At the end of the procedure you should be able to restore (within the limits of possible) all the chats that you thought were lost forever, plus their attachments, including videos if you had activated the appropriate function in the WhatsApp settings.
The procedure applies to all the most recent versions of WhatsApp and, as already mentioned, to all software platforms. Unfortunately it is not possible to switch chats from one operating system to another (e.g. from Android to iPhone), at least not officially, but we don't care about this at the moment. For now let's focus on reinstalling WhatsApp on terminals of the same type and see how to complete this operation. I wish you a good reading and a lot of fun!
How to reinstall WhatsApp on Android
If you want reinstall WhatsApp on your Android smartphone and you don't want to lose all the messages you had in the previous installation of the app, do it this way.
- Make sure the smartphone you are currently using is paired with the same phone number than the one on which you had previously installed WhatsApp.
- Make sure the smartphone you are currently using is paired with the same Google account than the one on which you had previously installed WhatsApp. If you don't know how, go to the settings of Android (the gear icon) and select the item first Account and then the logo of Google from the screen that opens. If your smartphone is associated with another Google account or no Google account, fix it by going to the menu Settings> Accounts and pressing the button Add account.
- If you still have your old phone handy or you want to reinstall WhatsApp on the same smartphone and you haven't uninstalled the app yet, launch WhatsApp, pigia sul pulsating (...) che si trova in alto a destra e seleciona la voce Settings from the menu that opens. Then go up Chat> Chat backup and verify that the backup function on Google Drive is activated. If not, tap the button Backup to Google Drive, put the check mark on Daily and presses the button Back up to start a backup of all your cloud conversations. If you want to include videos in the backup, check the item Include videos (but be aware that doing so will lengthen the backup and restore times and will take up more space on your Google Drive account).
After doing all the above checks, you can proceed to the actual reinstallation of WhatsApp. If you intend to reinstall the app on the same smartphone, then remove it and download it again from the Google Play Store.
If you don't know how to remove an application from Android, open the drawer (i.e. the screen where the icons of all the apps installed on the device are located), press and hold your finger on the icon WhatsApp and drag it to the basket which appears at the top left. Alternatively, go to the menu Impostazioni> App of Android and first presses the icon of WhatsApp and then on the button Uninstall.
As for the reinstallation of the application, there is not much to explain. After opening the Play Store (the shopping bag icon with the “play” symbol printed in the center), search WhatsApp, select the application icon from the list of results and first press on Install and then Accept.
At the end of the download, then start WhatsApp, follow the initial configuration procedure of the application and after verifying your phone number accept the restoration of the backup (which the application will automatically find on Google Drive) by pressing the button Restore.
Have you already removed WhatsApp from your smartphone and / or can't check for backups on Google Drive? In this case you can try to recover one of the backups made automatically by the application on the phone memory.
In addition to making backups on the cloud, the Android version of WhatsApp also saves chats on the smartphone memory and you can restore your conversations starting from the latter as well. In this regard, I recommend that you download the file manager ES File Manager from the Play Store and use it to get to the folder / Home / WhatsApp of your phone or the memory card inserted in it.
When done, select the folder Databases and choose one of the available backups (their name corresponds to the date they were created). Finally, press the button Rhinomine and change the name of the backup you want to restore to msgstore.db.crypt12 (This is not necessary if you want to restore the most recent backup, which should already be called this way). When you install WhatsApp again, the application will "see" the backup locally and ask you if you want to restore it.
You can also do the same “game” by taking the database with messages from another smartphone and transferring it to the folder WhatsApp / Databases of your new terminal (as long as you used the same phone number and the same Google account on the other mobile too).
In the event that WhatsApp fails to "see" the backup made locally, connected to this web page, log in to your Google account, remove WhatsApp from applications that have access to Google Drive and try again.
How to reinstall WhatsApp on iPhone
The procedure for reinstalling WhatsApp on iPhone is as simple as the one we just saw on Android. The application, in fact, performs an automatic backup of the chats on iCloud and allows you to restore them with each new installation, just a few taps are enough to complete the operation.
If you still have your old iPhone at hand or you want to reinstall the application on the same terminal and you have not yet uninstalled the app, you can check the status of the backups on iCloud by going to the tab Settings of WhatsApp and selecting the items Chat> Chat backup from the menu that opens. If the backup is too old or has never been done, press the button Back up now to create one. If in the backup you also want to include the videos received attached to the messages, move the lever relative to the option to ON Include videos.
Subsequently, if you have not already done so, uninstall WhatsApp from your "iPhone by" holding your finger on its icon on the home screen, pressing on x which appears at the top left and confirming the operation using the button Delete.
When the removal is complete, open theApp Store, search for WhatsApp Messenger and reinstall the application by pressing the button with the nuvola located next to its icon in the search results. Now you just have to start WhatsApp and follow the account reactivation procedure by typing your mobile number. Then press the button Reset Chat History and you will find all the conversations there where you left them.
The same operation can also be performed on a different iPhone than the one of origin of the messages, as long as you use the same Apple ID and the same phone number on both devices (but by now this should be clear, right?).
How to reinstall WhatsApp on Windows Phone
As mentioned at the beginning of the post, the Windows Phone version of WhatsApp does not have a cloud backup system, it saves conversations only on the phone memory, but this does not mean that you cannot reinstall the app and recover all the old chats.
To check the status of backups in WhatsApp for Windows Phone, start the application, press the button (...), select the voice Settings from the menu that opens and go up Chat and call. If the backup is dated or even absent, press on the item backup to create it "manually".
At this point, go to the screen with the list of all the apps installed on your Windows Phone, keep your finger pressed on the WhatsApp and select the item Remove from the menu that opens to delete the application from your smartphone.
When the operation is complete, open the Windows Phone Store (the shopping bag icon with the Windows logo printed in the center), search WhatsApp and reinstall the application by pressing the appropriate button. Now start the application, follow the initial configuration procedure of your account and press the button restore to restore the chat backup.
If you want to transfer your conversations from one Windows Phone to another, know that it can be done but only if the two terminals both have microSD support and are both associated with the same phone number.
To bring the backup from one Windows Phone to another, you must in fact transfer the microSD from the old terminal to the new one and install WhatsApp as we have just seen together.
