Security has been a sore spot for Android since its inception. With so many manufacturers making Android devices with their own customizations, it became impossible for Google to control updates. Instead, it has been up to the manufacturers to update devices.
With new exploits constantly being found and security being a hot topic, both the FTC and FCC launched separate inquiries into the security update practices in the mobile industry. The FTC is looking into Apple, BlackBerry, Google, HTC, LG, Microsoft, Motorola, and Samsung.
Monthly security updates are becoming more common lately, but only for certain devices. Cheaper and older devices are left in the dark, and security becomes a problem. Hopefully something productive comes out of these actions.
