Surprisingly, a lot of people only root their phones just because everyone else is doing it. It shouldn’t surprise you that there are still a number of people out there who have no idea the possibilities that opens up to you when you choose to root your device.
Granted, you’re taking a risk and you’ve lost your warranty already but then, I see no reason why you shouldn’t make the risk you took worth it. The benefits of rooting goes beyond having SuperSU to grant root access to installed apps only, there are so many things you can do with your device only if you’re willing to explore.
Unless otherwise specified, the apps listed in this article can be dangerous and should be used with care. But hey, it’s fun exploring the deep world of Android OS if you know what I mean.

Xposed Installer
This popular root app allows you to modify your device with
different the different modules available in the repository.
Xposed Installer itself is more like a framework and doesn’t
add any special functionality until you install modules. I
need to warn you though; you can brick your device by
installing this software . It’s not for the faint-hearted.
Gravity Box is an Xposed Installer module that lets you
customize almost everything about your UI. For instance,
you can decide to use a background image for your
notification center, change hardware key actions and many
more.

System App Uninstaller When your phone vendor installs bloatwares on your device, this is the right app you need to remove them. System App Uninstaller removes system apps that can’t be normally removed. This app doesn’t only remove system apps, it also manages your apps. However, it is advised you shouldn’t just go about uninstalling all system apps unless you’re sure of what you’re doing.

Disk Digger
Disk Digger is a very useful app that lets you recover
deleted files. It recovers deleted files right on your Android
device even if you’ve formatted your SD card.
You should note that the free version only recovers lost
photos and MP4 videos, you need to install the pro version
if you intend to recover other file types.

Pim.p My ROM
This is another app that lets your further personalize your
operating system and make things work just the way you
want. rom simple tewaks like setting WiFi scan intervals to
advanced ones like setting minimum & maximum CPU
frequencies, love-vendor My ROM is a root app any Android should
try.
There are apps and mods you can try out like the Sony
BRAVIA Engine 2 and more. However, it’s advised you
should use with caution as its still in Beta. Tampering with
what you don’t understand may have negative
consequences. Even the ones you’re sure of can send your
phone into a bootloop.

This is cool

Lucky Patcher This is one of the first apps I normally install after rooting my device. For each app, you can open the patch menu and do a few things like removing license verification, removing ads, changing permissions and more. Some apps too also support the custom patches preloaded with your lucky patcher install.

ES File Explorer ES File Explorer is more than just a file explorer, it has loads features and I think the name given to the app underestimates its capabilities. With root access, it can act a root explorer to access system files if you need to. There are also other features you can use without rooting your device like transferring files over WiFi.

Freedom
Developers need to make money to continue creating
awesome apps for us. I do not support cracking in anyway.
However, this app tends to bypass in-app purchases.
iFont
Just as the name suggests, this app changes the font on
your device. There are different fonts to chose from. This
does not necessarily need root access on some devices like
Samsung, Xiaomi and Huawei but you won’t be able to use
it without root access on other devices like HTC and Sony.
Greenify
As you use your device and install applications, it gets
slower overtime and starts lagging. This is due to some of
your installed apps always running in the backround. With
Greenify, you can hibernate these applications and speed
up your device.
It’s not really a root app anymore though, but there’s a
mode that needs Xposed Framework to function.
ROM Toolbox Pro
This is the all-powerful root app if you love installing
custom ROMs and modifying what you already have.
ROM Toolbox Pro combines the best features from apps like
Titanium Backup, ROM Manager, Root Explorer, SetCPU,
MetaMorph, Autorun Manager and others. It’s a paid software though.
Droid Wall
This app is not really dangerous but I decided to feature it, because it will be useful to most android users who want to manage their data consumption,this app allow you to choose the application, you want them to have access to the internet(data).

I still find rooting unnecessary.. At the end there is nothing your rooted phone can do that mine cant.

At least nothing important

You got it wrong big time. Your device is 40% not close to a rooted Android phone.

abeg all na wash...

To root your phone, kindly download King root. It's one of the best app for rooting Android phones. You can get it from Play store, or google search"king root apk".

Clean master is better than greenify, op didn't mention SuperSU

Thmbz up ma nigga

but my phone works just fine..does all it said it would and could do on the manual..

I can disable some system apps
Tweaking cpu and the rest is crap most times..i have friends who do it, their phone dosent fly yet
No i like the official roms, michael bricked his phone the other day trying whatever experiment or rom he wanted to do.
You hack apps? These days google has to verify the apps even after you intsalled..most times the patch dont work..i have tried several of them. But if it works for you, it would work for me too

Still yet to convince me man. Its not useless.. Bt why take such a risk that dosent mean much and loose your precious 13months warranty. Its like sucide

sorry ? which app have you tried patching? give examples

no doubt, your phone will work fine..

disabling system apps is different from uninstalling system apps

your phone is not meant to fly, at least you'd get something much reasonable than. stock rom. don't get me wrong stock rom is not always bad, sometimes it's more stable than some custom ROMs

There is something called "unbrick" you know. And most times you can solve this problems at least 80%

And you can unroot, you have that option in superuser, or flash your official rom

So your warranty is safe, expect for Knox that Samsung introduced recently
