GB WhatsApp Not Working? Troubleshooting Guide

1. Force-stop the app from Settings > Apps, then open it again.
2. Restart the phone.
3. Check free storage. A nearly full phone is a classic cause of crashes; keep at least a gigabyte spare.
4. Clear the app's cache from Settings > Apps > Storage. Do not choose "Clear data" unless you hold a backup, as that can remove your chats.
5. Check for an Android system update, since a pending one can cause odd behavior.
6. As a last step, reinstall the app, but only after you have copied a backup off the phone.

If the crash began right after changing a theme or font, revert that change or reinstall. Heavy custom themes are a frequent trigger. The release you have may also simply be old: the newest build listed here is 18.60, released September 30, 2026, and requires Android 6.0 or higher. Compare against your own on the versions page, and see how to update for the safe way to move forward.

Verification problems usually come from the phone, not the app. Check that the number is entered with the correct country code, that the SIM can receive SMS or calls, and that you are not on a weak or restricted network. Wait for the countdown to finish before asking for a call instead of an SMS.

• Turn airplane mode on and off, then try again.
• Move to Wi-Fi if mobile data is unstable, or the other way around.
• Do not request codes repeatedly; too many attempts can lock you out for a while.
• Make sure the date and time are set automatically.

If you are doing this during a restore, remember the number has to match the one used for the backup. See restoring chats.

This message needs plain talk. GB WhatsApp is an unofficial, third-party client, and WhatsApp's terms do not permit unofficial clients. WhatsApp has stated that accounts using them may be temporarily or permanently restricted. A message telling you to switch to the official app, or a notice that your account is temporarily banned, means WhatsApp has detected the unofficial client and is acting on it.

What you can and cannot do

• Reinstalling or updating the unofficial app will not remove a restriction imposed on your number.
• A temporary restriction may lift after a wait, and the notice usually shows a countdown. Using the unofficial client during that period can extend the problem.
• To get your chats back, you can try the official WhatsApp from Google Play once the restriction ends. Compatibility with your backup is not guaranteed.
• If WhatsApp offers a way to request a review, use the official channels. The WhatsApp Help Center (opens in a new tab) is the source for that, not third-party sites.

Delayed notifications are the most common complaint, and they are usually caused by the phone's battery management rather than by the app. Phones try to stop background apps to save power, and that can mean messages only arrive when you open the app.

1. Open Settings > Apps > the app > Notifications, and make sure notifications and the relevant channels are on.
2. In the same app page, open Battery and change the setting to unrestricted or not optimized. The wording varies by manufacturer.
3. Check that Do Not Disturb or any focus mode is not silencing the app.
4. Inside the app, review the notification and sound options, as some builds have their own.
5. Some manufacturers add extra "auto-start" or "background activity" lists. Allow the app there if present.

Allowing background activity uses somewhat more battery, which is the trade-off. If you have both the official and unofficial apps installed, check each has its own notification settings. The Android Help pages cover notification and battery options for most phones.

Messages stuck on the clock icon

Open a browser and confirm the internet works. Toggle between Wi-Fi and mobile data, check that data saver or a VPN is not blocking the app, and disable restricted background data for the app in its settings. Messages that stay pending usually mean no connection, not a broken app.

Storage and old releases

Low storage can stop media from downloading and make chats freeze. Old builds can also stop connecting once the servers change. Download a current release only from a source you trust, check its size and version against the published details, and follow the installation guide if you need to install again. If the install itself fails, see installation failed.

Still no luck? Look through the FAQ, or send details through the contact page: the exact message, your Android version and the build you use.
