The debloated ROM is not technically a custom ROM for the T-Mobile version of the Samsung Galaxy S5 smartphone, but it does offer people the feature that most like to see from a custom ROM which is the bloatware banished. Bloatware is the system apps that are installed on your smartphone carrier network or your OEM because they thought it would be an excellent idea for you to have the apps but you did not. As soon as these apps are not appealing to you, there is no reason to have them on your device unless the idea of having a worse battery and worse hardware performance somehow sounds appealing to you. The problem with these stock apps is that they are often really tough to uninstall, and that is where a ROM that offers them removed for you become appealing.

There are many ways we can remove bloatware without going to the trouble of installing a custom ROM but each of those ways requires knowledge — and pretty good understanding at that. The reason is because you will be removing the system apps manually and you need to know what is required for your operating system to run smoothly and what isn’t. From somebody who has tried this before, it is a lot easier to brick your device than you think. That’s why installing one of these debloated ROMs instead is the most appealing option.
