Solution to ongoing optimization problems and other crashes on WhatsApp

1. Restart WhatsApp several times

This solution applies to all types of locks and phones (iPhone, Android, Blackberry, Nokia, Windows Phone etc). You can try to restart the WhatsApp application even dozens of times when it crashes before you can get it to work. But, in the end, the result is achieved.

Close the WhatsApp application from the application bar (double press the Home button to bring up the application bar, touch the application for about 3 seconds and you should see a small “X”. Click on the “X” to close WhatsApp) .

Open the WhatsApp application and wait for it to load. Then close it again.

Repeat this procedure several times until WhatsApp works normally.

2. Facebook sync on iPhone

If you are using WhatsApp on iPhone and your phone suddenly freezes, most likely this is due to the fact that you have installed the latest version of Facebook on your phone, which has activated automatic synchronization with the phone book. To fix the crash problem, you may need to disable synchronization. Open the phone settings, go to Facebook and disable the synchronization with contacts under the heading “Allow these apps to use your account”.

3. Reinstall WhatsApp (for all smartphones)

The easiest way to restore Whatsapp after a malfunction is to delete the WhatsApp application and perform a new installation (therefore, reinstall the app). Before carrying out the deletion, it is recommended to make a backup , so as not to lose any data on the phone.

4. Problems updating WhatsApp

If WhatsApp crashes during an update, the problem could be that the installed file type is not compatible with the version of the operating system you are using on your mobile.
This is the case a common problem reported by several users:

“… during the optimization phase, the” optimization in progress “process seems to last an infinite time, as if it were frozen, usually on the value 100.”

If steps 1 and 2 did not solve the problem, proceed as follows:

5. Blocking during a chat

If WhatsApp crashes while you’re trying to have a conversation with a specific contact, delete the profile picture you set for that contact in your phone’s address book (or try removing pictures for all contacts you have in both your address book and WhatsApp chat).
