To install an alternative OS on an Android, you first have to attain root privileges. That’s right — most smartphone owners don’t even have full power over their smartphones. Attaining root on an Android was relatively straightforward in the early 2010s, but as the years passed by, newer Android phones became harder and harder to root. Rooting also comes with the wonderful consequences of voiding your warranty, so have fun with that.
After you’ve attained root, you need to flash a custom ROM (Read Only Memory) on the device, provided by the developers of the operating system you’re trying to install. After that, the steps are OS-dependent.
Meanwhile, you need just flash any Linux distribution on any regular old USB, plug it into your desktop, reboot into the USB, and install it from there. After that, it’s not as smooth sailing — Linux is notorious for hardware compatibility issues with certain components, but hey — at least you installed the damn OS.
The last gaping hole on the smartphone software scene is the update life cycle. Apple usually provides 5 or more years of updates for its iPhones — that covers iOS generations and security updates. That’s not bad.
Meanwhile, Google provides a measly 2 years. That means that after 2 years, any major cybersecurity vulnerability discovered in the last Android version that your smartphone uses will not get patched. That means if you value your security, especially if you do mobile banking, you need to purchase a new smartphone every 2 years.
The duopoly that Google and Apple has on the smartphone OS market has lead to terrible software design choices, lack of freedom, and possibly exposes users of this critical technology to hackers if they don’t barf up a couple hundred US dollars every 2 years.
If you’re rich (or American), you probably don’t care. You probably do already get a new phone every 2 years. But for the majority of the world that spends $200-$300 on their device and uses it for 6, it’s not as easy. And because of the lack of root privileges, there’s software in your device that you can’t control — and when you purchase a cheap phone, it’s most likely a Chinese one, and they’re not exactly the role model of respecting user privacy.
