Applications are designed for all the good reasons. But fishy use is also on incessant rise. Research shows 40% start with some online activity. 

Over fifty percent of users confirm that they are emotionally invested in someone online. And the major app behind this is WhatsApp because conversations go undetected on this app.

So when you see your partner more often on WhatsApp or to somewhat abnormal level, chances of infidelity are high on the messaging app.

Are you looking for ways to keep yourself aware of such happenings or you are sensing something fishy around? You are at the right place because we will help you out through different ways to sense anything going on and ways to confirm if it is true.

Part 1. 6 signs your partner is cheating on WhatsApp

In order to know whether your partner is cheating on you, note down the steps and methods highlighted below to see WhatsApp cheating messages:

1. WhatsApp online status increases, and online time is abnormal

One of the most common behaviors seen when your partner is cheating on you is their increasing WhatsApp online status. Your partner starts spending lots of time online.

This presence goes beyond what you normally experience with your partner. So if WhatsApp online status increases and online time reaches an abnormal level, your partner is potentially cheating on you.

2. WhatsApp updates become frequent

The next big thing is frequent WhatsApp updates if your partner is cheating on you. You haven't been seeing your partner that frequently on WhatsApp.

Then, suddenly, things became more frequent with WhatsApp updates. This is a major sign your partner is likely to be cheating on you.

3. Act happy while chatting on WhatsApp

Some may think of it as some normal action when we see something on social media apps. This could be a reaction to some funny status or some mate messaged your partner. However, this thing becomes frequent.

You start seeing your partner very often act happy while chatting on WhatsApp. This is a red flag that should warn you that there can be something fishy going on.

4. Your partner starts to pay attention to looks

Looks matter! When your partner starts cheating on you, he or she suddenly starts paying more attention to looks. This is an abnormal behavior that goes beyond just normal attentive behavior toward looks.

5. Keep his or her phone out of sight

If there is something fishy, this is normal human behavior to show as if he or she is keeping something away from others' sights.

Your partner should keep his or her phone out of sight to avoid letting you look at the screen when he or she is around you. This is something quite common and somewhat unignorable too. We see lots of humor and sarcastic approaches on social media about this act.

So be mindful of your partner's actions, especially if you see he or she starts to avoid letting you look at the screen when he or she is around you.

6. Your partner suddenly changes the phone password

Bad things are likely to happen when partners switch phone passwords. After all, not all partners work in some secret agency.

So unquestionably, hell can unleash! Your partner is loyal to you if he or she keeps one password or tells you if he or she makes any changes.

There is something going on that your partner wants to keep out of your sight. Sudden changes in password without your knowledge or behind normal behavior, your partner is potentially cheating on you.

Part 2. 4 ways to catch WhatsApp cheating (requires physical access to partner’s phone)

To know if your partner is cheating on WhatsApp, below are 4 ways to catch WhatsApp cheating.

Method 1. Directly ask to look at his or her phone

The most direct way to find out if your partner is cheating on WhatsApp is to ask to see his phone. When you check his WhatsApp, look for these:

Start by looking at the WhatsApp contact list: Any of the Android or iPhone contacts that have WhatsApp appear in the WhatsApp contact list.

If you see anything suspicious in WhatsApp contacts, like symbols or emojis instead of names, tap on the conversation with that contact, tap at the contact name, and then note down that number.

Compare that phone number to her phone's contact list to check the real identity of that contact.

Look for Deleted and Disappearing Messages: You may see deleted messages if your partner is trying to cover her tracks. If you see gaps in between exchanging conversations, then messages are possibly deleted.

Check the disappearing message settings. Partners hiding something use these settings, so messages are deleted automatically after a certain period. To check message disappearing settings:

Tap the chat to open it, and then tap on the name of the person at the top of the chat.

In Android, the Disappearing Messages settings appear at the top.

Check if there are multiple WhatsApp accounts: Go to settings on the WhatsApp application. Then click on the account. Then go to the Add Account menu. You'll see if your partner is using two accounts.

Method 2. Log in to WhatsApp web

In this method, you need to have physical access to the phone because when you log in, your partner will receive a prompt. For this purpose, you can ask for his phone for a few minutes.

The login process is:

Step 1. Go to https://web.whatsapp.com on any search engine. You'll see a QR code that needs to be scanned through the mobile app to get access to the WhatsApp account.

Step 2. Open the WhatsApp app on your partner's phone to scan your QR code, and select the three dots in the upper-right corner of the chat page.

Step 3. Select linked devices, and then hit link a device. Use your partner fingerprint or provide a passcode key if asked.

Step 4. Hold your partner's phone up to the QR code to pair it with the WhatsApp account.

Step 5. The WhatsApp account is now linked to the Web. You can see the current list of chats and see other features.

This is a good method, but it has limitations like:

• You can use it only on one computer at a time.
• You can't see when a message is delivered or read by any receipt.

Method 3. View media files on your partner’s phone

How to catch cheating partner on WhatsApp? The third method is viewing media files on your partner's phone. This is a simple process. You can do this by following the following steps:

For iOS:

Step 1. On the iPhone, open the Files app. If you don't see the blue Files app icon on your home screen, simply swipe down and then search for Files.

Step 2. In the Files app, search for the files you want to see.

Method 4. Recover WhatsApp deleted messages

Reinstalling WhatsApp could be the way to catch WhatsApp cheating. Backup of WhatsApp chat history on Google Drive on a daily, weekly, or monthly basis is a perfect way for backup. You can use it to restore any deleted or missing data.

Step 1. Uninstall WhatsApp from your partner's Android device, then go to the Play Store to reinstall it.

Step 2. Now, open the app and select the Agree and Continue button, and then select language.

Step 3. Sign in by entering your registered number. You will receive an OTP on the entered number for verification.

Step 4. After the verification, you'll see a prompt to restore your chat backup from Google Drive. Click the restore button to start the recovery process.

Step 5. Once the initialization is done, hit Next to fill in the information. You will be redirected to the chat screen as the process completes.

Media files, including photos, videos, documents, and more, will continue to download in the background on your partner's Android smartphone on WhatsApp.

This is a great method, but it has some limitations:

• Deleted or missing WhatsApp messages are only recoverable within the selected auto-backup period.
• Data before the next backup cannot be restored.
