A recent study and research on Android devices sold by well-reputed companies including Samsung, Huawei, and Xiaomi reveal that these companies lied to their customers about how secure their smartphones really are.
Smartphone companies often send security patches to improve your device’s security. Newer patches ensure more security and the companies are supposed to keep improving their firmware as new bugs and threats arise which can cause data leaks and hacks.
Facebook’s recent scandal shows how public data these days is highly vulnerable and controllable by high-end organizations – in the Android security patch case, companies have been claiming that their phones meet the latest security level while in reality, the devices ran an older version, missing necessary security fixes.
A Two-year Research
Researchers Karsten Nohl and Jakob Lell have been reverse engineering Android smartphones for the past two-years to check if the security patches have actually been included in firmware updates.
They discovered a “patch gap” in numerous smartphones in which companies simply changed the security patch date to the latest without actually updating the firmware.

If you navigate to your Android device’s settings, you can check its security level by finding your software information within “About Phone”.
But here’s the catch, this date can be changed easily without an update. Its done by editing the “build.prop” file which stores your device’s information such as model number, IMEI, and so on.
Samsung, Huawei, LG, and Xiaomi Included
Shockingly, almost every major smartphone brand has been concealing actual security levels. The researchers tested over 1,200 smartphones from several companies and it was found that Google’s Pixel and Pixel 2 were the only phones that had the latest security files.
Other than that, Samsung and Sony’s patch gap was smaller as compared to HTC, Huawei, and LG. Meanwhile, ZTE had the largest patch gap and has been missing out more updates as compared to other companies.
