Stock ROM is an operating system developed by manufacturer itself when we purchase a mobile.But, in stock rom the manufacturers limits the function and feature of the phone or tablet for our

safety purposes.A Stock ROM basically based on the Android platform and its open source. Any developer can

easily access the code and edit it, recompile it, and re-release it, this is called CUSTOM ROM.

In simple word,Its the modified version of stock rom.Custom ROMs are usually made by third-party developers which consist lots of customization.It can be used by other phones which can unlock extra feature also

increase performance and battery life at the same time.When some of the manufacturer company

stopped providing updates for certain devices which means you cannot get any further updates but at that time with the help

of custom ROM we can update our phones to next android version .

Advantages of Stock ROM​

Security – Security is the key reason why people prefer STOCK ROM over Custom ROM. Each stock ROM is developed by reputed companies so there is no chance for any kind of malware to attack

our device because some devices come with Locked Bootloader. Due to which you have to unlock the Bootloader in order to install Custom ROM.That is why your mobile is much safer due to security.

Warranty– As long as you are in the STOCK ROM, your mobile will have a warranty.That’s why most of the users shift to the STOCK ROM after the warranty void.And stick with STOCK ROM for that purpose.This is one of the

reasons why users don’t use custom ROM over Stock ROM.

However, even after unlocking the mobile bootloader, many manufacturing companies offer warranties, although.

-Disadvantages of Stock ROM​

-Performance

Manufacturers limit the device, as the device may overheat when it reaches its limit. Due to which you have to face problems from sometime during heavy task. Like multiple task or playing games, etc.

-Less Space Many unwanted apps come pre-installed in stock ROM. Which we cannot easily remove or uninstall, because these are system apps Which very quickly fills our mobile storage. It

is the most unliked part of Stock ROM.

-Updates -Most irritating part of Stock ROM is that you need to wait a long for your manufacturer to send

the update to get new and exciting features in your device. Also after sometime manufacturer, stops

sending the update. In that case, you are stuck on the same android version with old features.

-Advantages of Custom ROM​

-Customizable

Android Custom ROMs are highly customizable. It is very easy to install different custom ROMs nowadays. You can

easily customize the looks of the system ui and also enhance the performance of the system at the same time.

-Better Performance and Battery life

Like the Advantages, Custom ROMs have many disadvantages that many of you may not know about, here are some.

reversible.This means you will be able to return to the STOCK ROM and your mobile phone will have a warranty again if your device isn’t bricked .

Most of the time to install Custom ROM you need to have root installed on your mobile or have bootloader unlocked.

While unlocking devices or rooting most phones is easy, some phones require a complicated step to

install Custom ROM.Due to which many times our phone may be dead or our data may be lost

-Loss of data

To install a custom ROM, we have to wipe cache and format the data, many cases data on storage often deleted. You will be lost your saved settings and other

apps data also. Also formatting data and wipe cache cause you to lose contacts, messages, call logs, and apps backup and important documents etc etc.

-BUGS

Most of the custom ROMs are ported from other ROM, so if you want to use those features on your phone, you may have to face bugs sometimes.

Custom ROMs are complied by the developer not tested by any authority or genuine manufacturers. So,

it might contain some Bugs in it. If you are planning to install a Custom ROM then ready for face bugs.

-Security

to unlock the phone bootloader or root our device this is the first step. Manufacturer locked our device,

for this reason, no third party app can affect our phone. But our device might get infected by malware if

the device is unlocked or rooted.Also, Many times we can’t use banking related app on our phone because of its root.
