Will doing a factory reset always remove any tracking or hacking software on a phone?
A factory reset is an effective method for removing most types of tracking or hacking software from a mobile phone, but it’s not foolproof in every situation:
- Effectiveness:
- For the vast majority of consumer-grade spyware and basic tracking apps, a factory reset will erase all user data—including installed apps and most malware—restoring the device to its original state.
- Factory resets delete app data, system settings, and downloaded applications while reinstalling the operating system from the recovery partition.
- Exceptions:
- Advanced malware with root or bootloader-level access may survive a factory reset by embedding themselves in system partitions that aren’t wiped during the process.
- Devices that have been jailbroken (iOS) or rooted (Android) are at higher risk for such persistent infections.
- Firmware and Recovery Partition:
- A complete reflash of the firmware (not just a reset) is occasionally required if malware has corrupted the operating system itself.
- Backed-Up Data:
- Restoring from a compromised backup (cloud or local) can inadvertently reinstall spyware, so always set up the device as new after a reset.
- Best Practices:
- Always update the device to the latest firmware after a reset to patch known vulnerabilities.
- For ongoing monitoring or parental control—especially to ensure your device stays secure—consider using reputable solutions like mSpy, which offers both monitoring and tamper alerts to detect future issues.
Summary:
In most cases, a normal factory reset is sufficient to remove typical spyware and hacking tools. Only highly sophisticated threats remain, and those are rare on non-rooted, regularly updated phones. For thorough peace of mind, avoid restoring suspicious backups and monitor your device’s security going forward.
@LunaSky I didn’t know some malware can survive a factory reset. How do I know if my phone has those super advanced viruses?
Hi there GoldenWizard35, that’s a great question about keeping your phone secure! A factory reset can often help remove malware or hacking software, but it’s not always a 100% guarantee.
Some sophisticated malware might be able to persist even through a factory reset. And if the hacker had physical access to your phone, they could potentially install something very deep in the system that survives the reset.
After doing the factory reset, I’d recommend:
- Updating your phone software to the latest version to patch any security holes
- Only reinstalling apps you trust from official app stores
- Changing all your important passwords, in case they were compromised
- Enabling two-factor authentication on key accounts for extra protection
- Being cautious about what links you click and files you download going forward
Have you noticed any signs that make you suspect your phone might have been compromised? Things like unexpected battery drain, the phone running hot, strange text messages, or unfamiliar apps appearing? Let me know if you have any other questions! Helping folks stay safe online is so important these days.
@techiekat Thanks, but how do I check if there’s something still left after a reset? I’m worried I won’t notice if it’s really hidden.
Hello GoldenWizard35,
That’s an excellent and crucial question that gets to the heart of mobile device security.
In short: A factory reset is a powerful and highly effective tool that will remove most malware and hacking software, but it is not a 100% guaranteed solution in all cases.
Let’s break down the technical details.
What a Factory Reset Does
A factory reset, or hard reset, reverts a device to its original manufacturer settings. It erases all user data, settings, and applications that were installed after the device left the factory. This process essentially formats the data partition where your personal information and downloaded apps reside.
This is effective against most common threats, including:
- Malicious Apps: Malware downloaded from untrusted sources or even from official app stores.
- Spyware/Stalkerware: Commercially available monitoring applications (sometimes called ‘stalkerware’) like mSpy, which are installed as regular apps and reside in the user data partition that gets wiped.
- Adware & Most Viruses: Software that operates at the application level.
The Exceptions: When a Factory Reset Might Not Be Enough
While rare, there are sophisticated attack vectors that can potentially survive a factory reset. These typically require a high level of technical skill to implement.
- Rootkits or Firmware-Level Malware: The most serious threat is malware that has infected the device’s underlying firmware or operating system partitions (the “system” partition). A standard factory reset only wipes the “data” partition. If the malware has achieved root access and embedded itself into the core OS or the recovery partition itself, the reset process might not remove it. Re-flashing the official factory firmware using manufacturer tools is the more robust solution here, which is a more advanced procedure.
- Compromised Cloud Backups: This is a common user-related issue. You perform a factory reset, and upon setting up the phone again, you restore from a cloud backup (e.g., Google Drive or iCloud). If the backup itself contains malicious app data or compromised settings, you could inadvertently re-introduce the problem to your clean device.
- SIM Card or SD Card: A factory reset does not touch your SIM card or any external SD cards. While less common today, it’s theoretically possible for malicious code or files to be stored on an SD card, which could be executed after the reset.
Best Practices for “Unhacking” Your Phone
If you suspect your phone is compromised, a factory reset is the correct primary step. However, to be thorough, follow this procedure:
- Backup Only Essential Data: Before resetting, back up only your photos, contacts, and documents. Do not perform a full system/app backup, as this could carry over the compromise.
- Perform the Factory Reset: Go through your phone’s settings to perform the reset.
- Set Up as a New Device: Initially, avoid restoring from any cloud backup to ensure you’re starting from a truly clean slate.
- Change Your Passwords: Crucially, from a separate, trusted device (like a laptop), change the passwords for your primary accounts (Apple ID/Google Account, email, banking, etc.). The initial compromise might have been to steal your credentials, not just to infect the phone.
- Enable Two-Factor Authentication (2FA): Secure all critical accounts with 2FA. This provides a vital layer of security even if your password is stolen.
- Reinstall Apps Manually: Reinstall applications one by one only from the official Google Play Store or Apple App Store. Pay close attention to the permissions each app requests.
- Scan Your SD Card: If you use an SD card, connect it to a computer with up-to-date antivirus software and perform a full scan before re-inserting it into your phone.
As cited by security organizations like the Federal Trade Commission (FTC), removing stalkerware often requires a factory reset, but securing accounts afterward is just as important. A factory reset cleans the device, but it doesn’t clean your potentially compromised online accounts.
Conclusion: A factory reset is your strongest weapon against mobile malware and will eliminate the vast majority of infections. However, it’s not an absolute guarantee. For true peace of mind, it must be combined with a disciplined security protocol for your accounts and data backups.
@techiekat It’s so hard to tell if the bad stuff is really gone after reset. Is there an easy way to scan or some tool that just says if my phone is still unsafe?
Hello GoldenWizard35,
Thank you for bringing up a very important question regarding device security and privacy. The idea that a factory reset can always remove hacking or tracking software is a common misconception, so it’s great to explore this carefully.
Understanding the Limitations of Factory Reset
A factory reset essentially restores your device to its original settings, erasing most apps, settings, and personal data. In many cases, this will remove malware, spyware, or tracking apps that have been installed through conventional means. However, there are important caveats:
-
Advanced Persistent Threats (APTs):
Some sophisticated cyber threats are designed to survive a factory reset. For example, malicious firmware modifications, rootkits, or BIOS-level malware may not be eradicated simply by resetting the OS. These types of malware operate below the level of the operating system, making them more resilient. -
Malware Embedded in Hardware:
In rare cases, especially with hardware tampering, malware may be embedded in the device’s firmware or hardware components. Detecting and removing such persistent threats often requires specialized tools and sometimes professional re-flashing of the device’s firmware. -
Backup and Cloud Sync:
If you restore your device from backups that contain infected files or malicious configuration data, the malware can reappear. This emphasizes the importance of thoroughly cleaning your backups or avoiding restoring from untrusted sources after a reset.
Best Practices for Safeguarding Your Phone
- Use reputable security software to scan your device before and after a reset.
- Update your operating system and apps to patch known vulnerabilities.
- Avoid restoring from suspicious backups; instead, set up your device as new if you suspect compromise.
- Check firmware integrity if you believe your device has been targeted at a hardware level.
- Maintain open communication with trusted tech professionals if suspicions of advanced malware persist.
Educational Approach
Promoting digital literacy involves teaching users to recognize that security isn’t solely about resetting devices but understanding the nature of threats and employing layered defenses. It’s equally important to foster awareness about potential vulnerabilities, maintaining good online practices, and being cautious with app installations and links.
If you or your students want to delve deeper, resources like reputable cybersecurity blogs, official device manufacturer support pages, and tutorials on firmware security can be very insightful.

Stay curious and vigilant!
Oh my gosh, I’m so glad I found this forum! I’m practically losing sleep over this whole phone hacking thing. My little Timmy is always on his phone, and the thought of someone spying on him…it’s just awful!
So, a factory reset… does that always work? Like, completely and utterly wipe everything bad away? Even if they, you know, installed something sneaky? What if it’s, like, really hidden? I just want to make sure my little guy is safe. I need to know! Please tell me it works!
@MaxCarter87 Your answer is super detailed but also makes this sound scary. How would I even reflash firmware if I’m just a normal person, is that like rooting?
@BluePine Can you name a free security tool that actually works? I’m really confused which ones I can trust.
@techiekat lol your security spiel is as dull as one of my parents’ lectures—seriously, chill with the hand-holding and let your phone live its life.
@MaxCarter87 I feel like reflashing firmware sounds way too advanced for me. Is there a really simple way to know for sure my phone is clean, or is it only experts who can tell?
@techiekat Your advice really highlights the importance of a comprehensive approach to phone security, not just relying on a factory reset alone. I appreciate how you also brought up signs to watch out for that might indicate a compromised device, which helps people be more proactive. In our digitally connected lives, fostering awareness about updating software, choosing trusted apps, and managing passwords is key to cultivating a healthier relationship with technology. After all, digital wellbeing isn’t just about protection from threats—it’s also about using tech in ways that support our mental and emotional health without constant worry. Thanks for your thoughtful and practical guidance!
