Advantages and Disadvantages of Stock ROMs
Stock ROMs are the default Operating Systems which comes pre-installed with the Smartphone.
Stock firmware is the result of a lot of research and testing done by the operating system vendor, the device manufacturer and/or the mobile service carrier. Therefore, it carries several advantages:
1. It is usually quite stable upon release.
2. Almost all bugs are patched during the extensive beta testing before release.
3. It carries the official support by the firmware vendor, device manufacturer and the mobile service carrier.
4. Updates are pushed automatically to the device by the carrier.
Along with its advantages, stock firmware also carries its disadvantages and these include:
1. Updates aren’t frequent, as development is done mostly by corporations who have to follow a scheduled release cycle.
2. Providing feedback to the manufacturer in case of any issues is either impossible, unwelcome (often with Apple devices), or a long, tedious process.
3. Similarly, getting official support can be a hassle as well, involving a tedious process.
4. If the device manufacturer and operating system developer are different (as is the case with Android and Windows Phone 7), any updates released by the operating system vendor need to be edited by the device manufacturer or mobile carrier to add compatibility and additional software before release. Hence, some devices get updates delayed by months.
5. Updates are often released first in the United States, leaving the rest of the world waiting. (A world does happen to exist beyond the United States, we’ve confirmed it ourselves!)
6. Worse still, when manufacturers choose to no longer release official updates for their older devices in favor of newer ones, their users are essentially stuck with old versions of the operating system. This case is evident with many Android devices barely a year and a half old.
7. Several OS developers, device manufacturers or mobile service carriers add restrictions in the stock firmware ranging from locking the use of the device with one network/region to disabling sideloading of apps (we’re talking about you, AT&T) not available in the official app market, to advanced restrictions removing any chance of getting root access, just to name a few.
