When you think of exchanging your old phone or giving it to someone, there are some important things you should do first. If you do not do these things properly, your personal data may fall into the hands of others, which can cause big trouble. Here are some easy and important steps to make your phone completely safe:

1. Back up the data

It is very important to backup important data such as photos, videos, contacts and other files present in your phone. For this you can use Google Drive, iCloud or other cloud services. After taking backup, you can also store it on your computer or other device.

2. Log out of all accounts

Log out of all your social media, email, banking and other apps. Also, remove your Google, Apple or other ID from the phone. Don't forget to turn off tracking features like Find My Device.

3. Perform a factory reset

To completely format the phone, go to the phone settings and choose Factory Reset or Reset Phone option. This will completely delete your phone data. Make sure that no personal data is left in the phone after resetting.

4. Remove the SIM and memory card

Remove your SIM card and any memory cards from the phone. These cards may store your personal data, so it's important to remove them.

5. Note down the IMEI number

Make a note of the IMEI number before selling the phone. If you face any problem in the future, this information can be useful to you.

6. Physical condition of the phone

Clean the phone thoroughly and keep all the accessories like charger, cables and box ready. This can help you get a better price for the phone.

Remember that by taking these important steps you can ensure the safety of your data and bank details. If you are careless in any of these things, then your personal information can be misused.
