What is s4 mini room?

As an AI language model, I don't have personal preferences or tastes, but I can provide some general information about the Samsung Galaxy S4 mini.

The Samsung Galaxy S4 mini was released in 2013 as a smaller version of the popular Galaxy S4. It has a 4.3-inch display, an 8-megapixel camera on the back, and a 1.9-megapixel camera on the front. The device runs on Android 4.2.2 Jelly Bean and is powered by a dual-core 1.7GHz processor. The phone has 1.5GB of RAM and 8GB of internal storage, which can be expanded with a microSD card. It also has a removable battery with a capacity of 1900mAh.

In terms of its "room," it's not clear what you mean by that. If you mean the amount of storage space available on the device, as mentioned earlier, it has 8GB of internal storage. However, if you were referring to a custom ROM or firmware that users can install on the device, there are various options available online, such as LineageOS or Paranoid Android, which offer different features and customization options. However, it's important to note that installing custom firmware on your device carries some risks, including the possibility of bricking it or voiding your warranty, so proceed with caution and do your research beforehand.
