Changing a smartphone is always an exciting event, but it is often overshadowed by the fear of losing important information. The most valuable asset for most users is their messaging history. Unlike contacts, which are synchronized with your Google account automatically, private messages require a special approach and manual configuration of backup copies. The process of transferring chats to Android depends on the specific application, the version of the operating system and what platform you are moving from (from Android to Android or, for example, from iOS).
Fortunately, modern instant messengers, such as WhatsApp, Telegram and Viber, have developed convenient tools for data migration. However, many users encounter problems due to ignorance of the nuances: for example, lack of space in the cloud or incorrect configuration of access rights on a new device. In this article, we will analyze in detail the mechanics of the backup and recovery functions so that you can save the entire communication history without loss.
The mechanism of cloud backup
The main way to save correspondence history for most instant messengers is to use cloud storage. When you activate the autosave feature, the application creates an encrypted archive of your messages and media files, which is then uploaded to the servers Google Drive or the service’s own servers. This process occurs in the background and usually does not require user intervention if configured correctly.
It is important to understand the difference between real-time synchronization and backup. For example, in Telegram messages are stored directly in the developer’s cloud, so when you log into your account from a new device, the entire history is loaded instantly. At the same time, WhatsApp by default, it stores data locally on the device, and sends only a snapshot of the state to the cloud for a certain time. This means that if you don't make a backup manually before changing your phone, your latest messages may be lost.
For cloud backup to work correctly, you need to make sure that there is enough free space on your account. Google . Often, users ignore storage full warnings, which blocks the creation of a new backup. It is also critical to use the same phone number and the same Google account when restoring, otherwise the system will not be able to identify the desired data archive.
⚠️ Attention: When transferring data between different operating systems (for example, from iOS to Android), standard Google Drive cloud copying will not work directly. For such cases, special migration utilities are required, provided by smartphone manufacturers or the instant messengers themselves.
Before starting the transfer, be sure to connect your smartphone to the Wi-Fi network. Uploading and uploading large volumes of media files over the mobile data can take hours and significantly consume bandwidth.
Step-by-step guide for WhatsApp
Moving chats to WhatsApp is one of the most popular scenarios, as this application uses a local-cloud hybrid scheme. To successfully transfer your history to a new Android, you must first create a fresh backup on your old device. This is done through the settings menu of the application itself, where you can select the autosave frequency and initiate a manual backup.
After creating a copy on the old phone, the process on the new device is as follows: install the application, log in using same phone number. The setup wizard will automatically detect the presence of a backup copy in Google Drive and offer to restore it. Refusal of this offer at the initial setup stage will result in the fact that it will be impossible to restore chats later without reinstalling the application.
If automatic recovery does not work, you can try to transfer the data locally via a database file. To do this, you will need to find the file msgstore.db.crypt14 (the encryption version number may differ) in the folder Android/media/com.whatsapp/WhatsApp/Databases on your old phone and copy it to a similar directory on your new device before installing the application. This method is more complicated, but more reliable in case of Internet problems.
☑️ Preparing to transfer WhatsApp
It is worth noting that media files (photos, videos) may not be saved in full if the “Enable video” checkbox was unchecked in the backup settings. This often leads to the text of messages being restored, and instead of images, placeholders are left. Therefore, before migrating, always check your backup settings.
Features of migration to Telegram and Viber
Unlike competitors, Telegram works on the principle of a cloud messenger. This means that your entire correspondence history, with the exception of secret chats, is stored on the company's servers. When you install the application on a new Android and enter your phone number, all chats, channels and groups appear almost instantly. You don't have to worry about backing up or transferring files manually.
However, there is an important exception: Secret chats in Telegram are tied to a specific device and encryption keys. They cannot be transferred to another smartphone. When logging in from a new device, these chats simply will not appear, and the history in them will be lost. This is done for maximum security purposes, so that even if the account is stolen, the attacker will not gain access to confidential dialogues.
The situation with Viber is closer to the WhatsApp model. Backup via Google Driveis also used here. To successfully transfer, you need to go to More → Settings → Account → Viber backup on your old device and click “Create a copy.” On a new phone, the recovery procedure starts automatically the first time you log in, but requires the same Google account.
What to do with Telegram secret chats?
Unfortunately, the technical architecture Secret chats do not allow their export or transfer. The only way to save important information from them is to take screenshots or forward messages to yourself in a regular chat before changing the device.
Users Viber should also take into account that restoring from a local copy (without the cloud) is possible, but requires manual copying of the folder .Viber via a computer or file manager. This is relevant if you do not have access to the Internet or your cloud storage is full.
Using local files and PC for transfer
Sometimes cloud methods are unavailable or unreliable due to slow Internet. In such cases, the method of directly copying database files comes to the rescue. This method requires a computer or a second drive, and an understanding of the Android file system. Local copies are often created automatically by applications every night, even if cloud backup is disabled.
To implement this method, you need to connect your old phone to your PC in file transfer mode (MTP). Find the directory where the messenger databases are stored. The path may differ depending on the version of Android: on new versions (Android 11 and higher), access to the folder is limited, so it’s easier to use built-in file managers with root access or make a copy through the “Export chat” function inside the application. Android/data is limited, so it’s easier to use built-in file managers with root access or make a copy through the “Export chat” function inside the application.
After copying the files to your computer, connect the new phone and paste the files into the appropriate folders. It is extremely important to do this Before installation or launch the messenger for the first time on a new device. If the application was already running and created an empty database, you will have to delete the application, clear its data and repeat the procedure for inserting files.
| Messenger | Storage type | Path to local copy (example) | Google Account required |
|---|---|---|---|
| Local + Cloud | Android/media/com.whatsapp/WhatsApp/Databases | Yes (for cloud) | |
| Viber | Local + Cloud | Internal Storage/.Viber | Yes (for cloud) |
| Telegram | Only Cloud | Not applicable (cache) | No (number only) |
| Signal | Local | Internal Storage/signal-backups | No (file + password) |
⚠️ Attention: WhatsApp database files are encrypted. Simply copying a file
msgstore.db.cryptwithout the corresponding decryption key (which is tied to your Google account and phone number) on another device may not work. Always use the official recovery procedure within the application.
Transferring data between different ecosystems
The most difficult scenario is the transition from iOS to Android or vice versa. Apple backup protocols (iCloud) and Google (Drive) are not directly compatible. This has been a serious problem for a long time, but modern tools can solve it. For example, when initially setting up new Samsung or Pixel smartphones, it is suggested to use a Lightning-to-USB-C cable to directly migrate data from the iPhone.
The official tool from WhatsApp now allows you to transfer chat history from iOS to Android. To do this, you need to reset your new Android smartphone to factory settings (if it has already been configured), run the setup wizard and connect both phones with a cable. The system will offer to transfer data, including WhatsApp chats, which will be converted into a format understandable by Android.
For other instant messengers, such as Viber, the procedure is also simplified: in the settings on the iPhone you can create a backup copy, and then on Android when you log into your account, the system may offer recovery if you use the official migration utility from the phone manufacturer (for example, Smart Switch for Samsung or Move to iOS in the opposite direction). However, support for cross-platform transfer still depends on the specific phone model and OS version.
Cross-platform transfer (iOS ↔ Android) is only possible during the initial setup of a new device. If the phone is already activated, a full data reset will be required to launch the migration wizard.
Remember that when moving between ecosystems, some data, such as call logs within the messenger or specific privacy settings, may not be transferred. The main focus of the developers is on saving the text of messages and media files.
Common errors and ways to solve them
Even if all instructions are followed, users may encounter errors. One of the most common problems is the "Backup not found" message. Most often, this is due to the fact that a different Google account was entered on the new phone, different from the one that was used on the old device to create the backup. Check your email in your phone settings.
Another common problem is the recovery process getting stuck at a certain percentage. This may indicate a corrupted backup file or an unstable connection to the server. In this case, it is recommended to interrupt the process, delete the application, clear the cache and try to restore the copy again, preferably at night with minimal network load.
Also, users often forget about two-factor authentication. If you have enabled a PIN to log in to Messenger, it will be required when restoring to a new device. If you forget this code, restoring chats may not be possible for 7 days (security waiting period) as the system will block access to data.
⚠️ Attention: Application interfaces and file paths may change with software updates. If you cannot find the specified folder, use the file search inside the manager or check with the official help center of the messenger developer.
What to do if you forgot your two-factor authentication PIN code?
If you do not remember the PIN code and did not link an email to reset, you will have to wait 7 days. During this period, you will be able to use the application, but your chat history will not be restored. After the period has expired, you can reset the code and restore the data from the last available copy.
FAQ: Frequently asked questions
Is it possible to transfer WhatsApp chats without Google Drive?
Yes, this is possible by locally copying the database file. You need to copy the file msgstore.db.cryptXX from the Databases folder on your old phone to the same folder on your new phone before installing the application. However, this method requires root access or a special file manager on new versions of Android due to restrictions on access to the Android folder.
Will my groups be saved when transferred to a new phone?
Yes, information about groups is stored on messenger servers. After logging into your account with a new number (if it has not changed) or on a new device, you will automatically see all your groups. However, you will only remain in them if you did not sign out of them on your old device. Group administrators do not change during data migration.
Does the backup copy take up space in the phone's memory?
Yes, the local backup takes up space in the internal memory of the device. This is usually several gigabytes depending on the number of media files. A cloud copy in Google Drive does not take up space in the user’s quota only in the case of WhatsApp (when using a special hidden section), while backups of other applications can be counted in the overall storage limit.
What to do if chat recovery is stuck at 99%?
Do not turn off the phone right away. Wait at least 30-60 minutes, as unpacking and decrypting large databases can take a long time on weak processors. If the process does not budge for more than an hour, the file is most likely damaged. You will have to delete the application, download a fresh copy from your old phone (if possible) and try again.
Can I restore chats if I changed my phone number?
There is a “Change number” function inside the application, which you need to use on your old device before creating a backup copy. This will transfer your account and history to the new number. If you simply insert a new SIM card without using this function, you will create a new empty account, and old chats will not be retrieved automatically.
