There are two types of ROMs in Android ecosystem. As I mentioned above one is Stock ROM or the Firmware which comes pre-installed with any Android device and the second one is Custom ROM or commonly known as ROM. Custom ROMs are developed by third-party developers for a specific device. Most of the Custom ROMs are feature-packed and fast which makes them a better alternative to the stock firmware.

There are several things which make stock ROM better than Custom ROM. The stock ROMs are stable and get regular updates from the manufacturer. If there is a bug, that usually will be fixed by the next update. Stock ROMs get Google’s Latest Android Security patches via OTA updates on a regular basis which makes them much more secure than the Custom ROMs.

What Is Stock ROM and What are its benefits?

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 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.
