Just like how people like to choose where they shop for clothes to wear they also like to be able to choose what ROMs are running on their smartphones and tablets. There are loads of third-party developers out there who are not employed by Google and Android and are making ROMs for people to use that look different from the ones that Android developers make for you. The allure of these is pretty self-explanatory: they allow people to be running something on their devices that they like better than what Android had managed to give them. There is also a lot more to installing a custom ROM than just the looks alone. People can pick and choose what ROMs they want based on their uniqueness, and by that I mostly mean features. Each ROM differs from the next not only by looks but what you can do on them. Often this refers to certain apps being removed which results in greater battery life and hardware performance while other times it means adding features that Android and other ROMs never presented to the people. The result should leave people happier both from better looks that they find more appealing and more practical features that they can make use of instead of the ones that were on the device before, and they never used. A custom ROM gives the Samsung Galaxy Tab S device owners a chance to use something that better suits them instead of using the same old software that pumped out of the factory right around the world. And much like that pair of pants that you bought last month that you like so much, the new ROMs should also offer that same kind of opportunity to rock something that you love and can feel good about using.
Android developers do not mind you installing custom ROMs, but they don’t make them easy to install. They block off the chance to quickly install a new ROM by reducing the stock recovery partition not to include the option of uploading zip files which is what you need to get them loaded. We solve this problem by installing a custom recovery like Team Win’s TWRP Recovery and then we can install our custom ROMs. The other thing that many custom ROMs need is for the device to be rooted. The only exception to this is when the custom ROM that you are installing comes pre-rooted. Most manufacturers and phone carrier networks would prefer you to run the stock ROM because they offer these corporations the chance to make more money from your eyes and fingers after you originally purchased the device. They make this happen by the system apps that are running in the hopes that you use them which then, in turn, results in revenue ticking over for them some way or another. By replacing the stock ROM with a custom version, you’re usually removing these system apps that were allowing them to make the money and thus it makes them unhappy. Ethically, though, it should be up to you what you do with your device since you already bought it. If that means throwing it in the bin as soon as you get home or installing a new ROM, then that is your prerogative.
PhoeniX ROM V3.0
The first custom ROM that we saw available for the Samsung Galaxy Tab S tablet is the PhoeniX ROM, and we are glad that it was because it’s one that you should try if you like speed paired with something unique that will separate you from the pack. One of the main reasons as to why people like installing custom ROMs that doesn’t get talked about nearly enough is the fact that it allows people to be more of an individual–something that so many people want to be on a very subconscious level. While not a psychologist, I’m almost certain that is the reason for people having outrageous haircuts. You find many of the independent custom ROMs that came out have that uniqueness appeal, but you can’t trust many of them because you can tell skilled developers haven’t developed them. The Phoenix custom ROM here is different. Here you have a ROM that is unique and also developed well. You can run this custom ROM on your work phone and not have to worry about stability concerns.
Features: a unique PhoeniX Kernel V2.0, a ROM that is based on Android 5.0.2 Lollipop, plenty of status bar modifications, a unique Phoenix ROM control feature, new notification panel modifications. Moreover, you also get other modifications to the ROM in general, new buttons and display features, a data management option, new restart options, new utilities, loads of other changes.

The SimplerStock custom ROM is pretty self-explanatory in that it promises to give you another version of the stock ROM that comes even simpler. So by “simpler” what do they mean? Well, it essentially means the same thing as having the ROM debloated with all of the stock system applications removed that you did not want. One of the main reasons why people root the Samsung Galaxy Tab S tablet is to install something like the Titanium Backup application and then choose which system apps to remove from the list of applications. It isn’t as easy as it sounds though and it usually requires a level of expertise to do it correctly without removing the wrong system apps. Removing the wrong system apps can be severe and result in you bricking the device. That’s why many people prefer to install a custom ROM like the SimplerStock ROM, which already has taken care of all that for you instead.
Features: based on the Android 5.0.2 Lollipop software updates, comes completely debloated, so you don’t see any of the Samsung system apps that were slowing down your hardware and using up the battery power.

Android 6.0 Marshmallow ROM
As with many of the other custom ROMs for the Samsung Galaxy Tab S tablet, the Android 6.0 Marshmallow ROM is rather appropriately named too. The Galaxy Tab S has been around for a long time and to have a Marshmallow-based custom ROM available is truly unique. Android versions usually get better as time goes on because developers can hone their skills and do more. The one problem that can sometimes get in the way is that older hardware in the devices cannot handle what a new ROM requires. The Samsung Galaxy Tab S device is capable of handling this custom ROM that is based on Android 6.0 Marshmallow relatively quickly given that it is a tablet and not a smartphone. However, it is also helped by the fact that it is based on Vanilla Android sources and pure AOSP. You will need to install Google Gapps with this ROM if you want any of the Google stock applications. You can see the Open Gapps package available from the XDA-Developers thread in the first post when you click the download link below.

We have mentioned several custom ROMs available for the Samsung Galaxy Tab S smartphone that come to you debloated, meaning they lack the system apps. They do not always have all of the system apps removed, though, and without trying them ourselves, it is impossible for us to see exactly which apps are no longer there unless the original developers of the ROM choose to let us know in the information they provided. Suffice to say; we don’t ever really get that chance to fill you guys in on what is available and what isn’t–until a custom ROM like the Supernova ROM comes along.
