How to Use WhatsApp on a Tablet— Two Ways
For years, using WhatsApp on a tablet meant awkward workarounds and a browser tab that logged you out. That changed when WhatsApp rolled out companion mode: your tablet can now link to your phone’s account and run WhatsApp as a proper app, with your chats synced and your phone free to stay in another room. If your tablet does not support the app, WhatsApp Web still works as a solid backup.
This guide covers both methods step by step, the limits of each, and the fixes for the problems people actually hit. Before you start, check one thing: your tablet needs a stable Wi-Fi connection and your phone needs WhatsApp already set up and working, because the tablet links to that account — it does not create a new one.
Before You Start: What You Need
You need your Android tablet, your phone with WhatsApp installed and logged in, and about five minutes. Companion mode works on most Android tablets running a recent version of the operating system — if your tablet is very old, use the WhatsApp Web method below instead. Keep your phone nearby for the one-time QR scan, and make sure both devices are on Wi-Fi or mobile data. If you are new to using WhatsApp across devices, our guide to WhatsApp multi-device explains how the same account can live on four devices at once.
Method 1: Link Your Tablet as a Companion Device (Recommended)
This is the proper way. Your tablet runs the real WhatsApp app, your chats sync, and you can send and receive messages even when your phone is switched off.
Step 1 — Install WhatsApp on your tablet. Open the Google Play Store on your tablet, search for WhatsApp, and install it. If you see a message saying the app is not compatible with your tablet, skip to Method 2.
Step 2 — Open WhatsApp and choose “Link as companion device”. On the welcome screen, tap the three-dot menu in the top corner and select “Link as companion device”. A QR code appears on the tablet screen. Do not enter a phone number here — that path is for registering a new account, not linking.
Step 3 — Scan the code with your phone. On your phone, open WhatsApp, tap the three-dot menu, then “Linked devices”, then “Link a device”. Point your phone’s camera at the tablet’s QR code. The tablet will start syncing your chats, which can take a few minutes if you have years of messages.
Step 4 — Wait for the sync, then start chatting. Once your chats appear, you are done. Send a test message to a friend or to yourself to confirm everything works, then put your phone away — the tablet now works independently.
Step 5 — Optional: set it up for daily use. Turn on notifications for WhatsApp on your tablet so messages arrive even when the app is closed, and pin the app to your home screen or dock. If you share the tablet with family, use WhatsApp’s chat lock to keep private conversations behind your fingerprint or PIN.
Method 2: Use WhatsApp Web on Your Tablet (Works on Any Tablet)
If your tablet cannot install the app — older models, some budget tablets, or iPads running the browser — WhatsApp Web is the fallback that works everywhere.
Step 1 — Open your tablet’s browser and go to web.whatsapp.com. Use Chrome or your tablet’s main browser. If the page shows a “download the app” prompt, tap the browser menu and request the desktop site.
Step 2 — Scan the QR code with your phone. On your phone, open WhatsApp, go to “Linked devices”, tap “Link a device”, and scan the code on the tablet’s screen.
Step 3 — Bookmark it. Add the page to your home screen so it opens like an app next time. Your chats will load each time you open it, and messages will sync as long as your phone has an internet connection.
The trade-off is that WhatsApp Web on a tablet feels like a browser tab rather than an app: notifications can be unreliable, and voice and video calls work less smoothly. Our WhatsApp Web productivity tips show how to get the most out of the browser version if this is your daily setup.
What Works — and What Does Not
Linked as a companion, your tablet can send and receive messages, photos, voice notes, and documents, and you can join group chats normally. Video and voice calls also work on the tablet app, with the camera and microphone built in.
There are limits worth knowing. You cannot use the tablet as your primary device — if you log out of WhatsApp on your phone or delete the account, the tablet stops working too. Some features arrive on phones first and reach tablets later, and disappearing messages and live location behave the same as on your phone once set up. WhatsApp’s own Help Center keeps the official list of what companion devices support, and it is worth a quick check if a feature you rely on seems missing.
Fixes for the Problems People Actually Hit
The QR code will not scan. Brighten your tablet’s screen, clean your phone’s camera lens, and hold the phone steady about 20 cm away. If it still fails, tap “Link with phone number instead” on the tablet and enter the code shown on your phone.
Chats are stuck syncing. Leave the tablet on Wi-Fi with WhatsApp open for a few minutes. Large chat histories — especially ones full of videos — take longer. If the sync seems frozen, restart the app once and let it resume.
Messages arrive late or not at all. Check that your tablet is not killing WhatsApp in the background: go to Settings, then Apps, then WhatsApp, then Battery, and set it to unrestricted. Battery-saving modes are the most common cause of delayed messages on tablets.
The tablet keeps asking to link again. Companion devices disconnect if unused for a long stretch. Open WhatsApp on the tablet at least once every couple of weeks, and the link stays alive. If it does drop, re-linking takes the same two minutes as the first time.
Final Word
Companion mode is the method to use if your tablet supports it — real app, real notifications, and it works when your phone is in another room. WhatsApp Web covers every other tablet well enough for messaging. Either way, the setup takes five minutes and the payoff is a bigger keyboard and a bigger screen for the app you already use all day. Link it once, pin it to your home screen, and your tablet becomes a proper second screen for WhatsApp.
