Why won't my phone update?

Concerns & risks

You were trying to update your phone, but it keeps saying the update failed.

Missing updates leave security holes.

Causes & evidence

Common causes: low storage, low battery or no Wi-Fi. See software updates.

What to do

1. Free up storage.
2. Plug in and use Wi-Fi.
3. Restart and try again.

Common mistakes: Common mistakes: trying over and over with low storage. Free space, plug in, connect to reliable Wi-Fi and restart. If it still fails, update using a computer. Check whether your device still gets updates. Restart the phone, check the date and time are set automatically, and try again on a different Wi-Fi network. If storage is tight, delete big videos or unused apps first. If the phone is old, the manufacturer may no longer offer updates for it; check the official support page for your model's status. Avoid unofficial update files from random websites. Some updates also need a few gigabytes free just to unpack.

Speed Man tip: Old devices may stop getting updates; consider upgrading.

Wrap-up: Free storage. Plug in. Restart.
