Check the Package Name
The package name is the app’s unique identifier. For 558h, the official package name is: com.558h.android. You can check it with APK Info apps or through Android settings. Fake package names often look similar but include a typo or extra characters.

🏆 558h Certification & Verification
558h has earned certifications and verification from trusted international bodies to support app quality, security, and authenticity for users in Bangladesh.
Multi-Layer Verification
Every 558h release goes through layered checks from multiple security scanners, penetration testing, and code review by certified security experts to keep vulnerabilities as low as possible.
🛡️ Tips to Avoid Fake Apps
Check the URL Carefully
Always check the website URL — confirm HTTPS, correct spelling, and no odd characters. Phishing sites often use lookalike domains with typos.
Read Reviews & Ratings
Fake apps often have low ratings or suspicious reviews. Read user reviews to spot red flags such as malware reports.
Avoid “Mod APK”
Do not be tempted by “mod APK”, “unlimited features”, or “premium unlocked”. Modified apps almost always risk malware and account bans.
Check the Developer Name
Confirm the developer name on Play Store or the website matches the official developer. Fake apps often use lookalike developer names.
Enable Play Protect
Turn on Google Play Protect on Android to auto-scan apps and block harmful ones. It is a solid first line of defence.
Check Permissions
Review the permissions the app requests. If they do not match the app’s purpose (for example a calculator asking for contacts), be cautious.
Red Flags for Fake Apps
- Downloads from sites with many popup ads or redirects
- APK file size very different from the official Universal 38.7MB or ARM64 22.4MB builds
- App asks for permissions that are not relevant
- Very low rating or no reviews at all
- Unknown or suspicious developer name
- App has not been updated for a long time
- Too many “premium unlocked” claims that look too good to be true
