Morning. You tap the Gmail icon, half-reading a client's email on the lock-screen notification — and the app flashes white, stutters, and vanishes. Tap again. Same thing. Your email is still there, but the one app you need right now refuses to stay open for more than two seconds.
Your emails are safe: every message lives on Google's servers, and every fix below works on the app's local window onto them — nothing here can delete your mail. Covers Android 10 through 14.

Why Gmail Crashes While Other Apps Work Fine
Gmail crashing on launch while, say, WhatsApp runs perfectly is not a coincidence — Gmail leans on system components that most apps never touch:
- Android System WebView: Gmail renders email bodies through WebView. A buggy WebView update has, more than once, broken Gmail on millions of phones overnight while everything else kept working.
- Constant background sync: Gmail syncs mail, labels, and contacts continuously. An interrupted sync — a dead zone mid-download, a half-written cache file — can leave local data it can't recover from on next launch.
- Bloated local database: years of attachments, offline mail, and search indexes pile up. A corrupted index entry can crash the app every time it tries to display the inbox.
- Aggressive battery savers: Xiaomi's HyperOS and some Samsung One UI builds kill Gmail's background processes mid-sync, which corrupts exactly the data the app needs at launch.
The good news: nearly all of these are fixable in under five minutes, in the order below. One distinction saves wasted effort — if Gmail opens fine but new mail never arrives, that's a sync problem, not a crash, and our Gmail not syncing guide covers it instead.
Fix 1: Force Stop Gmail and Restart the Right Way
Swiping Gmail away in the recent-apps list doesn't fully close it — zombie background processes can survive and crash again the moment you reopen the app. A proper force stop kills every one of them:
- Open Settings → Apps → Gmail (tap the app, don't just find it in a list).
- Tap Force stop and confirm.
- Now restart your phone — don't skip this. A restart clears stuck background services and releases RAM that low-memory phones desperately need for Gmail's next launch.
- After the reboot, open Gmail directly from the app drawer (not from a notification) and watch whether it stays open for at least 30 seconds.
If Gmail survives, the crash was a stuck process — done. If it still dies within seconds, Fix 2 goes straight at the app's stored data.
Fix 2: Clear Gmail's Cache (the 30-Second Fix)
Gmail keeps temporary files — message previews, thumbnails, half-downloaded attachments — in a local cache. When one of those files corrupts, the app can crash every single launch trying to read it:
- Go to Settings → Apps → Gmail → Storage (on Samsung One UI: Settings → Apps → Gmail → Storage; on Xiaomi HyperOS: Settings → Apps → Manage apps → Gmail → Clear data screen, then choose only cache).
- Tap Clear cache. This touches nothing personal — no emails, no account, no settings. Just temporary files.
- Do NOT tap Clear data yet — that's Fix 4, and it signs you out. Stay on cache for now.
- Force stop Gmail once more, reopen it, and let the inbox load fully. The first load after a cache clear is slower — that's the app rebuilding clean files, a good sign.
If you want the full rundown of what cache clearing does (and doesn't) across every app, our guide on how to clear app cache on Android goes deeper.
Fix 3: Update Gmail, WebView, and Chrome
If Gmail started crashing right after an update — or your phone auto-updates apps overnight — you're probably looking at a version bug. The Gmail-specific twist: the crash often isn't in Gmail at all. It's in Android System WebView, the component Gmail uses to render email bodies. A bad WebView update once crashed Gmail on phones worldwide:
- Open the Play Store, search Gmail, and tap Update if available.
- While you're there, search Android System WebView and update it too. On some phones (especially Samsung) you won't find WebView in the Play Store — on those devices Google Chrome handles WebView duties, so update Chrome instead.
- If the Play Store shows Gmail as "up to date" but crashes started today, check Play Store → your profile → Manage apps & device → Updates available — pending WebView updates hide there.
- After updating, restart the phone before opening Gmail. WebView changes only take effect on a fresh boot.
- Nuclear option for WebView-caused crashes: Settings → Apps → Android System WebView (tap the three-dot menu → Show system first if it's hidden), tap the three-dot menu → Uninstall updates, then restart. This rolls WebView back to the factory version. Re-update it from the Play Store a few days later.
The pattern to remember: crashes right after an overnight update → suspect WebView first. That's the one fix unique to Gmail-style crashes.
Fix 4: Clear Gmail's Data and Sign Back In
This one resets Gmail's local database — the synced mail index, offline messages, and account settings on the phone. It's the fix for crashes that survive Fixes 1–3, and your mail re-syncs from Google's servers afterward.
- Go to Settings → Apps → Gmail → Storage and tap Clear data (labeled Clear storage on some phones).
- Confirm. Gmail will open like a fresh install — signed out, inbox empty. That's expected.
- Open Gmail and sign in with your Google account. Wait for the initial sync to finish before judging — on a large inbox this can take several minutes, and interrupting it mid-way is exactly how corrupted data happens.
- Re-check your Gmail notification settings afterward (Gmail → ☰ → Settings → your account → Notifications), since a data clear resets them to defaults.
- If you use multiple accounts in Gmail, add them one at a time and test between each — a single account with a huge corrupted offline store can be the one crashing the app.
Fix 5: Remove and Re-add Your Google Account
Sometimes the crash isn't in Gmail's files at all — it's in the account sync state. A stale authentication token makes Gmail crash the moment it tries to verify who you are. Removing the account resets that state completely:
- Go to Settings → Accounts (Pixel), Settings → Accounts and backup → Manage accounts (Samsung One UI), or Settings → Accounts & sync (Xiaomi HyperOS).
- Tap your Google account → Remove account. Note: this signs you out of every Google app on the phone (Play Store, Drive, Maps), but deletes nothing — your data is all in the cloud.
- Restart the phone.
- Go back to Settings → Accounts → Add account → Google and sign in fresh.
- Open Gmail and let it sync fully. If the crash is gone, the account state was the culprit.
If you use 2-Step Verification, keep your verification method handy — you'll need it on sign-in.
Fix 6: Reinstall Gmail and Free Up Storage
Last resort for the app itself, plus the cause people forget — a nearly full phone can't give Gmail the space it needs to launch:
- Uninstall Gmail: Settings → Apps → Gmail → Uninstall (on some phones Gmail is a system app and only offers Uninstall updates — take that option instead, then restart).
- Restart the phone, then reinstall Gmail from the Play Store.
- Before opening it, check storage: Settings → Storage. If you're under ~1–2 GB free, Gmail has no room to build its cache — delete large videos, clear other apps' caches, or move photos to the cloud.
- Check for a system update: Settings → System → System update (Pixel), Settings → Software update (Samsung), Settings → About phone → System update (Xiaomi). Old OS versions running new Gmail builds is a real crash source.
- As a diagnostic, open mail.google.com in your phone's browser. If mail loads fine there but the app still crashes after a reinstall, the problem is specific to the app install — repeat the uninstall, this time declining any cloud backup restore of Gmail's data.
If Gmail crashes alongside other apps too, the problem is bigger than Gmail — our general guide to apps that keep crashing on Android covers the system-wide causes.

FAQs
Will clearing Gmail's cache or data delete my emails?
No. Clear cache only removes temporary files. Clear data removes the app's local copy — settings, offline mail, the local index — and signs you out. In both cases your emails live on Google's servers and re-sync when you sign back in. The only loss with a data clear is local-only settings like notification preferences.
Why does Gmail crash the second I open it, but works in the browser?
The browser version (mail.google.com) doesn't use the app's local database, cache, or WebView — it renders server-side. App-only crashes point at corrupted local data (Fixes 2 and 4) or a buggy WebView update (Fix 3). If both fail, check your connection or Google's server status instead.
Gmail started crashing right after a phone update. Is that related?
Very likely. System updates can change WebView, battery optimization, or background sync behavior, and Gmail is sensitive to all three. Work Fixes 3 and 6's update checks first: update WebView/Chrome, then check for a follow-up system update — Google and phone makers often ship a patch within days.
