Where can we check for latest security patches?
You can find them at

Checking out the latest security patches level at that page allows you to keep updated on monthly device updates. The page contains the available Android Security Bulletins, which provide fixes for possible issues affecting devices running Android. However, fixes from SOC manufacturers are available directly from the manufacturers. That means you cannot pick the latest patch(es) from Android Security Bulletin page but you have to obtain the update directly from your phone’s manufacturer.

The point is, to be always updated and try to not missing any security update.

These top 3 reasons give you a valid justification of why you should always keep updated:

  1. There have some viruses targeting Android devices. To name them a view: QuadRoot, Spectre, Meltdown, etc. are the perfect examples. These viruses could have harmed your device on a serious level. Therefore, patches are absolutely necessary.
  2. System Updates also bring newer Android versions at times. It means you can be more productive. New Android version may also help you to save storage, memory, etc. Remember that there are always reasons why either Google or phone manufacturer releases newer version of ROM/Firmware.
  3. Nevertheless, if you do not received new updates every month, just keep calm and need no worry. Some phone manufacturer like Motorola has decided against monthly update. Alternatively, the new security patch are rolled multiple patches together into a single one as a big update. One thing for sure, there is always update no matter when it will be released. The only thing you have to do is to immediately update your phone when a new security patch is released.

Some phones throw and option to ignore updating your phone. Again, never ignore a new firmware / ROM update especially if it includes security patches.
