WhatsApp Messenger Not Installing on Samsung A73 5G Despite Download Completion

I’m having trouble installing WhatsApp Messenger on my Samsung Galaxy A73 5G. Yesterday, I uninstalled the app and tried reinstalling it, but although the download completes, I receive the error message: “WhatsApp Messenger couldn’t be installed.”

I’ve tried several troubleshooting steps, including using different internet connections (both Wi-Fi and mobile data), trying different Google accounts, restarting the device, and checking my storage space. Other apps install and run without any problems — this issue occurs only with WhatsApp.

My device is no longer under warranty, and I don’t recall whether I recently performed a system update. I haven’t yet contacted WhatsApp or Samsung support, and there was no payment involved during installation.

I’m requesting technical support to fix this issue as soon as possible so that I can reinstall and use WhatsApp Messenger again on my Samsung Galaxy A73 5G.
