What is WhatsApp, and how is it different from other messaging apps?
WhatsApp is a free messaging app that lets you send texts, voice notes, photos, videos, and files, and make voice or video calls over the internet. Unlike some other apps, WhatsApp uses end-to-end encryption by default and works smoothly across mobile and linked devices.
Can I use WhatsApp without my phone being online?
Yes! With multi-device support, WhatsApp now allows you to use it on up to four linked devices even if your phone is turned off or disconnected from the internet. Just link your devices once using a QR code, and you're good to go.
Where can I safely download WhatsApp for Android, iOS, or desktop?
You can download the official version of WhatsApp for Android, iOS, Windows, and macOS directly from Fileion. We offer secure, malware-free downloads that are always up to date.
Why won’t WhatsApp open or load on my phone?
This can happen if your app is outdated, your device has low storage, or there’s a network issue. Try restarting your device, updating WhatsApp, clearing cache, or reinstalling the app from Fileion to fix the problem.
How do I fix QR code scanning issues when linking devices?
If the QR code won’t scan, clean your phone camera lens and ensure the screen brightness on the other device is high. Check your internet connection and try again. Restarting both devices often helps.
Is it safe to use WhatsApp on a shared or public device?
It’s better to avoid using WhatsApp on public devices. If you must, never save login details and log out after each use. Always enable fingerprint, face unlock, or PIN protection on your phone to manage linked devices securely.
Can I make group calls using WhatsApp?
Yes! WhatsApp supports group calls with up to 32 participants for audio and 8 for video. Whether you’re catching up with friends or having a remote meeting, the calls are smooth and encrypted.
Does WhatsApp support sending large files?
Absolutely. WhatsApp allows you to send files up to 2GB in size—including videos, PDFs, and documents. Just select the file from your device or drag and drop it on desktop, and it will be sent securely.
Why am I not receiving notifications from WhatsApp?
First, check that notifications are enabled in both your device settings and WhatsApp settings. Also, make sure your device isn’t in battery saver or do-not-disturb mode. If using on desktop, keep the app or browser tab open in the background.
How can I log out or unlink a device from WhatsApp?
Go to WhatsApp > Settings > Linked Devices on your phone. From there, you can log out of any connected session with one tap. This is especially useful if you stop using a specific computer or device.
Does WhatsApp work on Linux?
WhatsApp doesn’t have an official Linux app yet, but Linux users can access WhatsApp through a browser using WhatsApp Web. Some unofficial apps exist, but they aren't supported by WhatsApp and may have security risks.
Can I use two WhatsApp accounts on one phone or PC?
You can use two accounts by using Dual Apps (on Android) or WhatsApp Business alongside the standard version. On PC, open one account in WhatsApp Web and another in a separate browser or profile.
Why is WhatsApp running slowly on my device?
If WhatsApp feels slow, it may be due to low device storage, outdated software, or background apps consuming resources. Clear cache, update the app, and close unused apps to boost performance. Reinstalling from Fileion can also help fix lag issues.
