Do you want to sell your old phone and upgrade to a new mobile?
1. Photos and videos must be backed up
If you are giving away your old Android phone to others, you must first back up the important data in it. The data you back up includes many of your photos, videos, documents, messages, and contacts. If you have not already backed up, you can use cloud-based services like Google Photos, Google Drive, One Drive, Dropbox to back up your photos/videos. This method is much better than manually transferring your photos and videos to a PC or external hard drive.
2. Contacts included
Contacts must be set to sync to Google Contacts. However, for some reason, it is better to double-check your contacts twice a day. You also have the option to export (export) the contacts into the memory cart and import (import) them into your new device. By transferring important documents on your phone to cloud applications like Google Drive and Dropbox, you can also access them from your PC.
3. WhatsApp is also important
Most people usually forget to back up their chat history. If you are using WhatsApp, you need to create a backup into the application settings and upload it to Google Drive. Otherwise, you will not be able to transfer the chat history on your old phone to the new phone. To back up your important SMS messages, you can use the SMS Backup & Restore application.
4. Backup app data too
Since we usually back up app data, open an app that contains important data, and use it if you have an internal backup option. Also, make sure to back up the apps that have two-factor authentication on your old Android phone.
5. Better to call
Most of us have a laid back attitude when it comes to selling an old phone. If you are selling your old Android phone after you buy a new phone, you can transfer all your data to the new phone. But the problem here is that transferring application data between Android devices is not that easy. There is no official solution to this from Google.
6. There is a solution but not completely
Although some OEMs (Original Equipment Manufacturers) offer applications specifically for backup, they do not work with some brands of devices. Once the application is working, the expected results do not appear. You can use the Smart Switch if you want to transfer data between Samsung devices. For OnePlus phones, the OnePlus Switch application can be used. Although a different version of Android is installed on both phones, these applications may not work. So when making such a transfer make sure that the Android version is the same on both the phones.
7. Delete Google Account
As long as you have your old Android phone, it will have Factory Reset Protection (FRP). It complies with the security standards introduced by Google. It is a good idea to turn off this FRP before you sell your old phone / tablet. For this you need to remove all the Google accounts you have signed in on your mobile. You need to go into the settings on your smartphone. Then select your Google Account in the Accounts section. If you click on Remove Account there it is as if you are logged out of that mobile. In addition it is best to delete other accounts as well.
8. Also do a factory reset
After you have removed all your data from your mobile and created a backup, it is advisable that you perform a factory reset on your mobile. This will allow you to delete all the accounts you have signed in on your mobile. Also it can be very difficult for those who bought your smartphone to log into those accounts.
9. Clean everything and remove the SIM / Memory cards
So far you have taken care of all the software aspects. Now remove the SIM / Micro SD card from your old Android phone. It is also a good idea to thoroughly clean your mobile using a damp microfiber cloth. Because our minimum responsibility is to keep your mobile clean while giving it to others who have been dirty for years. It is also a good idea to set up and provide other accessories that you have available, such as the purchase bill, warranty, box, charger, and earphones for the phone.
10. Where to sell your old phone
Once you have completed all of the above, you can boldly give or sell your old phone to your friend or family. If you want to sell your old phone to someone you can use online websites like 2-gud, OLX.
