How to back up your Android phone before a factory reset
Selling, repairing or just starting fresh? Here's the short checklist that actually covers everything worth saving.

A factory reset is permanent the moment it starts. Here's the checklist worth running through first, in the order that catches the most easily-forgotten things.
Photos & videos first
Confirm your camera roll is actually backed up — open your cloud storage app directly and check the photo count matches, don't just trust that "backup is on." Auto-backup can silently stall on a bad Wi-Fi connection for weeks without telling you.
Chat app media and history
Photos and chat history inside WhatsApp, Telegram and similar apps usually live in their own backup system, separate from your phone's general cloud backup. Open each chat app's settings and trigger a manual backup — don't assume it's covered by your general phone backup.
Saved files and downloads
Anything in your Downloads folder, PDFs, voice memos, scanned documents — these often aren't swept up by photo-focused backups. Move anything you need into a cloud drive folder manually.
App data that doesn't sync automatically
Some apps (certain games, note apps, offline tools) store data locally with no cloud sync at all. Check each app's own settings for an export or backup option before you reset — once the app's gone, that data usually is too.
Two-factor authentication and passwords
If you use an authenticator app for two-factor codes, confirm it has cloud backup enabled or note down the recovery codes for each account. Losing access to your authenticator without a backup can lock you out of accounts in a genuinely painful way.
Write down what's signed in
A quick mental (or actual) list of what's logged into this device — banking apps, email, work accounts — makes it much faster to verify everything's reconnected correctly afterward, and flags anything you should sign out of remotely first.
The actual reset
Once everything above is confirmed, factory reset is genuinely simple: Settings → System → Reset options → Erase all data. Do this over Wi-Fi if possible — it can take a while, and you don't want it interrupted.
Done in this order, a factory reset is a non-event instead of a risk. Most "I lost everything" stories come from skipping the chat-app and local-file-only categories above, not photos — those usually are backed up by default already.
