Can I uninstall and reinstall the Gmail app?

Last reviewed: October 1, 2026 · Markdown version

Yes on iPhone, and on Android usually only if Gmail did not come with the phone. Either way, your email is not stored in the app. It lives in your Google Account, which is why Google counts "Gmail messages and attachments, which includes your Spam and Trash folders" against your account's storage rather than your phone's (How your Google storage works, read 1 October 2026). Delete the app and sign back in later, and the mailbox is where you left it.

What can be lost

The things that only ever lived on the phone. Google does not list what uninstalling Gmail removes; its Play help page on deleting apps gives the steps and is silent on app data (Delete apps on your Android device, read 1 October 2026). The closest Google comes is its warning about clearing the Gmail app's storage on Android, which "can erase your" message drafts, signature, ringtone and other settings (Fix sync errors with the Gmail app (Android), read 1 October 2026). Apple is direct about its side: "Deleting an app removes it and its data from your iPhone." (Remove or delete apps from iPhone, read 1 October 2026). So before you uninstall: send or copy out any draft you care about, and note your mobile signature.

On Android: uninstall, or only disable

If you installed Gmail yourself, it comes off like any app: Play Store, your Profile icon, Manage apps & devices, Manage, select it, Uninstall (the Delete apps page above). If it came with the phone, Google's answer is different: "You can’t delete some system apps that came pre-installed on your Android phone. But on some phones, you can turn them off", and for how, it says to contact the manufacturer (Disable apps that came with your Android device, read 1 October 2026).

Getting it back is the same screen in reverse: Manage, then This device, Not installed if it is not listed, then Install or Enable (Reinstall & re-enable apps, read 1 October 2026).

On iPhone

Touch and hold the Gmail icon, tap Remove App, then Delete App. Do not stop at Remove from Home Screen: Apple says that only moves the app to App Library, and "it isn’t deleted" (the Remove or delete apps page above). To reinstall, open the App Store, tap your picture, then Apps & Purchase History, Your Apps, and redownload Gmail from the list (Redownload apps from Apple, read 1 October 2026). Then sign in again, so have your password and second step to hand before you start.

Will reinstalling fix the problem?

Often it is not the step Google reaches for. Its sync troubleshooter for the Android app runs from a manual refresh and an app update, through a restart, the connection, sync settings and both kinds of storage, and ends with clearing the app's storage; reinstalling Gmail is not on the list (Fix sync errors with the Gmail app (Android), read 1 October 2026). If the app is slow rather than broken, the cheaper steps on why the Gmail app is slow come first. If a reinstall is what you want anyway, it is safe for your mail; just mind the drafts.
