If the Best Buy app will not load, sign in, or add items to your cart, first check whether your phone can reach the internet. Then try the low-risk fixes—reopen the app, restart your phone, and install updates—before clearing Android cache or reinstalling. If BestBuy.com also rejects your sign-in, treat it as an account issue rather than an app-only problem.
1. Check your internet connection
Open a browser on your phone and load a familiar website. If that fails too, switch between Wi-Fi and mobile data or try another Wi-Fi network. A weak or unavailable connection can look like a Best Buy loading failure; this is a general connection check, not a Best Buy-specific outage diagnosis. Google recommends checking the connection and trying another network when Android apps or websites cannot connect (Google Play Help: internet connection problems on Android).

2. Close and reopen the app
Dismiss Best Buy completely from your phone’s recent-apps view, wait a moment, then launch it again. On Android, force-stopping an unresponsive app is among Google’s recommended troubleshooting steps. Menu names and gestures vary by device (Google Play Help: fix an installed Android app that isn’t working).

3. Restart your phone
Restart the phone, then open Best Buy again. A restart is a simple way to clear a temporary app or connection hang; Google also recommends restarting when an installed Android app crashes, will not open, or stops responding (Google Play Help).

4. Update the Best Buy app
Open the App Store on iPhone or Google Play on Android, search for Best Buy, and install an available update. Best Buy recommends checking for app updates regularly or enabling automatic updates. Its official app page links to downloads for both platforms (Best Buy Mobile App; Benefits of the Best Buy App).
5. Check for a phone system update
Look in your phone’s system settings for an available operating-system update, install one that your device supports, then reopen Best Buy. Google includes Android system updates in its general app troubleshooting guidance. The exact settings path depends on the phone maker, so follow its instructions rather than relying on a universal menu name (Google Play Help).

6. Clear the app cache on Android
If Best Buy still misbehaves on Android, open Settings, find Apps, select Best Buy, and look for Storage or Storage & cache. Choose Clear cache. Labels and locations differ across Android versions and manufacturers. Prefer clearing cache to clearing storage or app data: clearing data is more disruptive and may remove saved app state or require you to sign in again. The available guidance does not establish an equivalent Best Buy cache-clearing procedure for iPhone (Google Play Help).

Before removing the app, make sure you know how to access your Best Buy account. Uninstalling can erase data saved in an app, and reinstalling is not a guarantee that a particular cart or local state will return. Download Best Buy again only from the App Store or Google Play, then sign in. Best Buy provides official app-download links on its mobile app page; Google also explains how to reinstall Play Store apps (Google Play Help: reinstall and re-enable apps).

8. Work out whether it is the app, your account, or the cart
When the app fails but the website works
Open BestBuy.com in your phone’s browser. If the site works while the app does not, continue with app-specific steps and use the website as a temporary alternative. Best Buy says a signed-in account can save cart items between shopping sessions, but that does not establish that every cart issue is caused by the app or that reinstalling will restore a cart (Benefits of the Best Buy App).
When sign-in fails on both
If you cannot sign in through either the app or BestBuy.com, use Best Buy’s password assistance page. The reset process uses a verification code. Best Buy says creating a new password removes billing information from the account, so review payment details before your next checkout.

When the problem persists
Best Buy’s app page directs customers to its mobile FAQ or to call 1-888-237-8289 for app help (Best Buy Mobile App). Its contact page provides account and order support. The FAQ endpoint linked from the app page could not be opened on October 4, 2026, so use the contact page if that link does not work for you. The official pages reviewed do not confirm a current outage or provide an outage dashboard.
