Why You Must Wipe Your Phone First
Leaving accounts, photos, messages, or saved passwords on a device not only renders the device useless to a buyer but also potentially exposes your identity and personal history. To remove accounts, disable activation locks, and get the phone back to its original out-of-box state, please follow the steps below.

Android Phone Step-by-Step Wipe Guide
Note that the options menu will vary by manufacturer, but these core steps apply to Samsung, Google Pixel, OnePlus, and most Android phones. Regardless of the brand, you must remove your Google Account before performing the factory reset to disable Factory Reset Protection (FRP):
- Back up your data
Use Google Backup, Google Photos, or the manufacturer’s backup tool to save contacts, messages, photos, and settings. - Remove the Google account and disable FRP
Open Settings > Accounts, then remove your Google account. Removing the account prevents Factory Reset Protection from locking the Android phone for its next owner. - Sign out of other services
Log out of the Samsung account, Facebook, Gmail, and other apps that remain linked to the device. - Encrypt the device if available
For extra security, enable encryption under Settings > Security if the device offers it before resetting. - Factory reset
Go to Settings > System > Reset options > Erase all data Factory reset. Confirm with your PIN, password, or pattern. - Remove SIM and the SD card
Physically remove the SIM card and any external microSD card you may have installed. - Final check
When the phone restarts, it should display the initial setup screen, confirming that the wipe was successful.
How to Erase a Non-Working or Damaged Phone
If the screen is cracked, the phone won’t power on, or it’s lost, you can still protect your data remotely or prepare for safe disposal.
In case of the remote wipe, the erasure will begin automatically the next time the phone connects to the internet:
- iPhone Remote Erase
Sign in to iCloud and use Find My to select your device, then choose Erase iPhone. After erasing, remove the device from your account to disable Activation Lock. - Android Remote Erase
Use Google’s Find My Device to sign in, choose the device, and select Erase Device. If remote erase is unavailable, remove the device from your Google account to prevent future access. - If remote erase fails or the phone is irreparable
Remove the SIM and, if possible, physically destroy or remove storage components before recycling. Use an authorized e-waste recycler that is certified in secure data destruction and has the necessary equipment to physically shred or dismantle the phone, destroying the internal storage chip (eMMC or SSD).
Quick Pre-Sale Checklist
- Your photos, contacts, and messages are backed up
- Signed out of Apple, Google, and manufacturer accounts
- Find My and Activation Lock are disabled for iPhone, or the Google account is removed for Android
- Factory reset completed and setup screen visible
- SIM and SD cards removed
- The phone is cleaned, and the accessories are located and organized for sale or recycling.
While smartphones depreciate quickly (manufacturers expect us to upgrade yearly), if your iPhone or Android cell is less than four years old, still functions, and has no major cosmetic blemishes, consider checking if you can sell it before exhausting other options.
Why reselling pre-owned technology matters
- It extends the lifecycle by at least another three years on average
- It allows the owner to recoup some cash from their outdated phone
- It provides affordable tech to those who cannot afford to pay full price at the retail store.
