When you click on it, a list of actions will appear, from which you must select Delete or the trash icon. The system will ask you to confirm the operation to prevent accidental data loss.
If you want to delete several records in a row without entering each one separately, use the mass selection mode. To do this, in the main contact list, press and hold your finger on the first entry until a check mark appears. After this, you can mark other numbers and click the delete button in the top panel.
- 📱 Open the application Contact and find the desired number.

Using third-party applications for batch cleaning
Standard tools Android 5 sometimes cannot cope with mass cleaning, especially if the telephone the book contains thousands of entries. In such cases, it is advisable to use specialized utilities from the store Google Play. These applications allow you to select groups of contacts based on various criteria.
Popular contact managers, such as Contacts Optimizer or Cleanerscan the database and offer to delete empty entries, numbers without names, or duplicates. Installing such an application requires granting access rights to the phone book, which is a standard procedure for this type of software.
After scanning, the application will generate a list of candidates for removal. You can view it and confirm bulk deletion with one click. This saves time compared to manually clearing each entry through the standard menu.
⚠️ Warning: Third-party applications may have access to your entire phone book. Download only proven utilities with a high rating and a large number of reviews in the official store.

Recovery of deleted contacts and backup
Before embarking on a total cleanup, it is important to understand the mechanisms of data recovery on Android 5. If you deleted contacts by accident, your chances of getting them back depend on where they were stored and whether syncing was turned on. It is extremely difficult to return numbers that are locally deleted without a backup copy.
Google provides an automatic backup feature. If it was active, you can restore your phone book to any date in the past (up to 30 days ago). To do this, you need to go to your Google account settings on the website and select the "Cancel changes" option.
To prevent data loss in the future, it is recommended to regularly create file exports .vcf. This can be done in the import/export menu of the Contacts application, saving the file to a memory card or internal storage. Such a file can be opened on any device and the list of numbers can be restored.
⚠️ Attention: The settings menu interface on different firmware (Samsung, LG, Sony) may differ slightly from the standard one Android 5.0. The names of the items may vary, but the logic of the actions remains the same.
Set up automatic synchronization of contacts with Google once a week to always have an up-to-date backup copy in the cloud without any extra effort.
Frequently asked questions (FAQ)
Is it possible to restore contacts after clearing data applications?
If you did not enable synchronization with your Google account and did not manually export the file, then it is almost impossible to restore contacts after clearing application data. The data is physically erased from the device's memory.
Why do deleted contacts appear again after a reboot?
This happens if the contacts are synchronized with a Google account or another service (for example, Facebook or Skype). Deleting them on your phone does not remove them from the cloud, and they will be downloaded back the next time you sync. You need to delete them through the account web interface.
How to delete all contacts on Android 5 at once?
The fastest way is to go to Settings → Applications → Contacts → Memory → Erase data. You can also select all contacts in the application through the menu (three dots) → Select all → Delete, if such an option is available in your firmware version.
Does deleting contacts affect the operation of instant messengers?
No, deleting a number from the phone book does not delete your account from instant messengers (WhatsApp, Viber, Telegram). However, the contact name in the correspondence may be replaced by a phone number, since the application will not be able to match the number with the name.
Where are deleted contacts stored on the SIM card?
There is no trash can on the SIM card. When you delete a contact from your SIM card, it disappears immediately and irrevocably through your phone. Recovery is possible only with the help of special equipment for reading chips, which is not available at home.
