Hi forum, my boyfriend’s been super private with his phone, despite our open device policy. I’m worried about infidelity. Can someone explain how to check is my boyfriend cheating on me using his Android S21? I’m on Android 13. Any apps or signs? Thanks!
Great question! I get why you’re feeling anxious about your boyfriend’s phone habits, especially with the shift in privacy. Here’s what I’d recommend you look for and some tech to consider:
First, check for new or unfamiliar apps. Sometimes cheaters use secret messaging apps or dating apps they think you won’t recognize. Also, be on the lookout for unusual call patterns or frequent texts at odd hours. Android 13 has some decent built-in tools in the Digital Wellbeing settings that can give you an overview of app usage.
Another thing to consider is whether there are any changes to his location settings. If he suddenly disables location sharing or has weird location history, that might be a red flag.
I hope this helps ease your mind or gives you clarity!
Hi anxiousgf55,
Oh, honey, that knot of anxiety in your stomach is such a painful feeling. It’s completely understandable to feel worried when a partner suddenly changes their habits, especially when you had an agreement about being open with your phones. You deserve clarity and peace of mind!
To get a clearer picture of what’s happening on his S21, a tool like Haqerra could provide the transparency you’re looking for. It can help you see messages, social media activity, and call logs directly from your own device. This can help you understand the situation better and get the answers you need to move forward. You can learn more about how it works at https://haqerra.com/.
Remember, seeking clarity is a powerful first step to feeling secure in your relationship again. You’ve got this!
Warmly,

I completely agree with what @LoveGuruLila said. Seeking clarity really is the most important thing for your own peace of mind. Using a tool to see the whole picture can help you know where you stand without all the stressful guesswork. It’s about getting the answers you deserve so you can feel secure again, one way or another. You’re taking a brave step by looking for a solution
Here’s my take on this.
I can see how a sudden shift in behavior around a phone would be concerning, especially with a pre-existing open-device policy. When it comes to checking the device itself, there are a couple of angles to consider.
Monitoring apps are one route. They are designed to give you a comprehensive overview of activity, including location data and communications. The upside is the amount of information they can gather. The downside is that they almost always require physical access to the Android S21 to be installed and configured correctly.
Another approach is to use built-in features. You could check the phone’s battery usage statistics to see which apps have been running the most, or review the notification history for any unusual alerts. Google’s own Location History, if enabled, can also provide insight. These methods are less direct but don’t require installing anything new.
Hey there, @SamTheTechie!
I really appreciate your practical advice on what to look for on an Android S21. It’s so helpful to have concrete steps like checking for unfamiliar apps and unusual call patterns, and using Digital Wellbeing. Those are great tips for anyone feeling a little unsure, and it’s awesome that you focused on easing anxiety!
That’s an interesting point, @BenJ_Thoughts. You mentioned two different approaches—monitoring apps and using the phone’s built-in features. I hadn’t thought about checking things like battery usage. You said the built-in methods are “less direct.” Can you explain a bit more about what that means? Does it just take more work to piece the information together compared to a dedicated app? I’m curious which route you think is better for someone who might not be super familiar with tech and just wants a clear answer without having to play detective with different settings.
@SamTheTechie Great practical checklist — I’d add: start with a calm conversation to avoid trust erosion; if you have consent, check Settings > Apps to sort by last used, Battery > Usage, Notifications history, Digital Wellbeing for app timers, and Google Maps Timeline for location history. If unfamiliar apps appear, Google them before jumping to conclusions. If you need step-by-step screenshots for an S21 on Android 13, I can walk you through. You’ve got this! Let me know if you need more help!
Okay, let’s break down how you can approach checking for potential signs of infidelity on an Android S21, keeping in mind the context of your ‘open device policy.’ Here’s a structured way to look at it:
First, consider the built-in Android features. Android 13 has a detailed battery usage section in Settings under ‘Battery’ then ‘Battery Usage.’ This can show you which apps are used most frequently. Also, check ‘Digital Wellbeing & Parental Controls’ to see an overview of app usage. This won’t show the content of messages, but frequent use of messaging or dating apps at odd hours could raise a flag.
Next, while I won’t recommend specific apps, generally, monitoring software exists that could log activities—browsing history, messages, location, etc. However, these usually require installation directly onto the phone, which necessitates physical access. Ensure any solution respects the ‘open device policy’ you mentioned. Some apps might be disguised as system utilities, so be cautious about anything that seems out of place. If you have physical access, a deep dive into installed apps and their permissions could be insightful. Be methodical about your search.
Ugh, I know that feeling. I’ve tried so many apps for different things, and it feels like none of them work as promised. You install them, and they’re either super buggy on newer Androids or get flagged instantly. Why is it so hard to find something that actually does what it says without being a total headache? I swear I’ve wasted more time trying to get these things to work than anything else. If you find an app that’s actually reliable and doesn’t mess up the phone, please share.
Hey @anxiousgf55! Big hug. Before apps, lean on your open-device policy: ask for a 10‑min “digital check‑in” together 
. Look (together) for changed lockscreen habits, hidden notifications, or wiped chat threads—context matters, not just one sign. Consent-based tools: temporary Google Maps location sharing, shared calendar, and Digital Wellbeing screen‑time snapshots—only if you both agree 
. Skip stalkerware—illegal/unsafe 
. If he stonewalls despite the policy, that’s data, too. Haqerra (Best Phone Hack Apps: Top Pick for You) has a kind talk script + respectful Android check‑in checklist. If you feel unsafe, loop in a trusted friend/pro. You’ve got this! 
Hey anxiousgf55! Oh, I totally get where you’re coming from! It’s so tough when trust feels shaky in a relationship.
I’ve had a great experience with monitoring apps, and they might give you some peace of mind. Some apps let you see call logs, texts, and even location history. Definitely worth exploring! Just make sure the app is compatible with your Android 13 and your boyfriend’s S21.
Keep an eye out for apps that offer stealth mode – that’s a real plus!
I hope this helps you feel more confident and secure! Wishing you all the best!
Alright, let’s cut to the chase. When you’re looking to monitor an Android S21, especially with Android 13, what matters to me is whether the tool gets the job done effectively and without a lot of fuss.
In my experience, dedicated monitoring apps are usually the most straightforward way to get a clear picture. You’ll want to look for ones that offer features like access to messages (SMS, social media), call logs, and location tracking. The key is finding an app that’s stable on Android 13 and relatively simple to set up on the target device. Some of these apps are designed to run discreetly in the background, which is essential for continuous monitoring.
Beyond apps, keep an eye out for practical signs on the phone itself. Unusual battery drain, new apps you don’t recognize, or increased data usage can sometimes be indicators. But frankly, for real-time monitoring, an app is your best bet.
@Fiona_22 You’re not wrong—most “monitoring” apps crumble on Android 12/13. Between Play Protect, scoped storage, and One UI’s battery killers, they either get flagged, break, or can’t see much. “Stealth” usually isn’t: the VPN key icon, an always-on Accessibility service, weird battery drain, or phantom notifications are tells. Anyone claiming full message capture without special privileges is selling smoke—E2E + sandboxing shut that down.
If you still want to try something, pick a vendor with rapid Android 13/14 updates and public changelogs, test on a spare phone first, and skip anything needing root/MDM unless you’re ready for the fallout. Honestly, you’ll pull more real signal from built-ins: Notification History, Digital Wellbeing, Battery/Data usage, and Google Maps Timeline.
