[icon name=”sticky-note” class=”” unprefixed_class=””] Stock ROM’s are the ones that come pre-installed on phones or tablets. These are the versions of Android developed by the OEM’s for making their phones look unique. They also come with pre-installed with certain apps.

The reason for the usage of Custom ROM’s over Stock ROM’s are:

1) Security: These ROM’s are developed by big companies and hence there are fewer chances of malware/ virus affecting the phone.

2) Warranty: Installing a Custom ROM needs root access and this voids warranty of your smartphone in most cases. A lot of OEM’s do not allow the root access or customization.

3) Pre-installed apps and features: A lot of these ROM’s come with pre-installed apps which are sometimes useful. These apps vary between different manufacturers and even for models. Some OEM’s also give their customers premium features like Launchers, wallpapers, home screen, etc.
