If your phone says it's "out of storage" and won't take photos or update apps, you can fix it in a few simple steps without losing your pictures or contacts. This guide walks through it slowly, in plain language, for both iPhone and Android.

Short answer:

  • Open your phone's Storage screen to see what's full (iPhone: Settings > General > iPhone Storage; Android: Settings > Storage).
  • Delete old videos, clear app cache, and remove apps you don't use, none of which touches your contacts.
  • Empty the Recently Deleted album afterward so the space is actually freed.

First, See What Is Taking Up Space

You don't need to guess. Your phone can show you exactly what's full, and it's easier than it sounds.

  • iPhone: open Settings, tap General, then tap iPhone Storage. Wait a few seconds for the list to appear.
  • Android (Samsung, Pixel, etc.): open Settings, then tap Storage (sometimes under Battery and device care).

You'll see a list, usually with the biggest items at the top. Most often Photos and Videos use the most space, followed by apps. This screen is just for looking, nothing is deleted by opening it.

Delete Old Videos (They Use the Most Space)

Videos take up far more room than photos, so removing a few long ones frees a lot of space quickly. Your other photos stay safe.

  1. Open the Photos app.
  2. Tap Albums, then look for Videos (under "Media Types").
  3. Tap a video you no longer need, then tap the trash can icon to delete it.

Start with the longest videos and any screen recordings. If you're unsure about a video, leave it, only delete ones you know you don't want. You can always ask a family member to help decide.

Empty the "Recently Deleted" Folder

Here's a step many people miss: deleted photos and videos don't leave your phone right away. They sit in a special folder for 30 days, still using space.

  • iPhone: in Photos, tap Albums, scroll down to Recently Deleted, open it, tap Select, then Delete All.
  • Android: in Google Photos, tap Library (or the menu), open Trash or Bin, and choose Empty.

Only after you empty this folder is the space truly freed. This single step often clears up more room than people expect.

Clear App Cache (Safe Temporary Files)

Apps like Facebook, YouTube, and your web browser save temporary files called cache. Clearing the cache frees space and does not delete your account, photos, or messages.

  • Android: go to Settings > Apps, tap an app like Facebook, tap Storage, then tap Clear cache. Important: tap Clear cache, not Clear storage or Clear data, those would log you out.
  • iPhone: apps don't have a cache button, so for a heavy app you can delete and reinstall it, then sign back in. Your account information comes back when you log in.

Clearing cache is safe. The only thing to avoid is "Clear data" or "Clear storage," which signs you out. Our Android cache guide explains this gently if you'd like more detail.

Remove Apps You Don't Use

Old apps you never open still take up space. Removing one is easy and you can always reinstall it later for free.

  • iPhone: in Settings > General > iPhone Storage, tap an app you don't use and choose Offload App (keeps your info) or Delete App (removes everything).
  • Android: in Settings > Apps, tap an unused app and choose Uninstall.

Only remove apps you recognize and don't use. If you're not sure what an app is, leave it. Your contacts, photos, and messages are not stored inside these apps, so removing a game or extra app won't affect them.

A Simple Routine to Stay Clear

You don't need to do everything at once. A little, now and then, keeps your phone happy:

  • Once a month, check your Storage screen and delete a few long videos.
  • Empty the Recently Deleted folder afterward.
  • Clear the cache on apps you use a lot.

If reviewing photos and videos one by one feels like a lot, a review-first cleaner can help. Clenoir on iPhone or Cleanor on Android scans your phone and gathers your biggest videos and duplicate photos into a list, showing each one so you (or a family member helping you) can confirm before anything is deleted, nothing disappears without your okay. For more easy steps, see the clean up phone storage guide and the storage cleanup FAQ. With a few minutes of tidying, your phone will have room for new photos again, and your important memories stay safe.

Want the fast version? Cleanor for iPhone scans on-device — nothing uploaded — and surfaces your largest videos, duplicate photos, and heavy caches in one pass. For the full routine, see the free up phone storage guide.

FAQ

How do I see what is filling up my phone's storage?

On iPhone open Settings, tap General, then iPhone Storage and wait a few seconds for the list. On Android open Settings then Storage (sometimes under Battery and device care). This screen is just for looking and nothing is deleted by opening it.

Why is my phone still full after I delete photos and videos?

Deleted photos and videos sit in a Recently Deleted folder for 30 days and still use space. On iPhone open Photos > Albums > Recently Deleted, tap Select then Delete All; on Android open Google Photos > Library > Trash (or Bin) and choose Empty. Only then is the space truly freed.

Is clearing an app's cache safe, or will it log me out?

Clearing cache is safe and does not delete your account, photos, or messages. On Android, go to Settings > Apps, tap the app, tap Storage, then tap Clear cache, not Clear storage or Clear data, which would log you out.
