Is there a way to delete multiple contacts on I phone?

Yes, there is a way to delete multiple contacts on an iPhone. Here’s how you can do it:

1. Open the Contacts app on your iPhone. This app is pre-installed and can usually be found on your home screen.

2. In the Contacts app, select the "All Contacts" tab or any specific group that contains the contacts you want to delete.

3. Tap on the "Edit" button located in the top-right corner of the screen.

4. Now, you can start selecting multiple contacts to delete. To do this, simply tap on the circles next to each contact’s name. A checkmark will appear indicating that the contact has been selected for deletion.

5. After selecting the contacts you want to delete, scroll to the bottom of the screen and tap on the "Delete" button. A confirmation pop-up will appear.

6. Confirm the deletion by tapping on "Delete from My iPhone" in the pop-up window.

7. The selected contacts will now be deleted from your iPhone.

It’s important to note that deleting contacts from your iPhone will also remove them from other devices that are connected to the same iCloud account. Additionally, if you have contacts synced with other platforms or accounts, such as Google or Outlook, the deleted contacts will be removed from those as well.

Remember to be careful when deleting contacts to avoid accidentally deleting important information. It’s always a good practice to create a backup or export your contacts before performing any deletion actions.

How did someone else’s contacts get on my Android phone?

It can be disconcerting to find someone else’s contacts on your Android phone. Here are a few possible explanations and steps you can take to address the issue:

1. Syncing with the wrong account: Check if your phone is syncing with multiple accounts, such as Google, Microsoft Exchange, or social media accounts. Sometimes, contacts from another account may have been accidentally synced to your device. To resolve this, go to your phone’s settings, find the accounts section, and ensure that you are only syncing with the correct account.

2. Phone restoration or backup: If you recently restored your phone from a backup or transferred data from another device, it’s possible that the contacts came from the previous owner or the associated backup. In such cases, it’s crucial to ensure that you restore or transfer data from a trusted source. To resolve this, you may need to reset your phone and set it up again, carefully selecting what data or accounts to restore.

3. Sharing or importing contacts: If you have recently received contacts from someone or imported contacts from a third-party source, it’s possible that the contacts you’re seeing belong to another person. Review your recent activities, contact imports, or shared files to identify any potential sources. Remove or delete any unknown or unwanted contacts manually.

4. Malware or unauthorized access: Although relatively rare, it’s possible that your device has been compromised by malware or someone gained unauthorized access to your phone. In such cases, it’s crucial to ensure that your phone has the latest security patches and perform a thorough scan for malware using trusted antivirus software. Additionally, review your security settings, change passwords, and consider enabling two-factor authentication for your accounts.

5. Contact merging or linking: Android devices sometimes automatically merge or link contact information from various sources, such as email accounts or social media. It’s possible that the contacts you’re seeing are not directly on your device, but rather linked to your own contacts. To address this, review your contacts app settings and unlink or separate any unwanted or merged contact information.

Remember, the steps to resolve the issue may vary depending on your specific device’s manufacturer, model, and Android version. It’s always a good practice to regularly review and manage your contacts, ensuring that you only keep the necessary and trusted information on your device.
