The Samsung Galaxy Tab SM T 230 and T230NU don’t support cellular communication. In other words, no SIM card can be inserted.
With the 7 inch TFT capacitive touchscreen, the display is buttery smooth and you get very fast responses to clicks and swipes.
When it comes to the build, both the T230 and T230NU look attractive. The plastic doesn’t feel cheap and holds well in the hands.
It’s large but can fit into your hands without causing too much discomfort. The screen dimensions sit at 17.78cm with a WXGA (1280 x 800) screen.
Display ratio of 16:9 ensures that the images are crisp, clear and do not lack any details.
The back facing camera sports just 3 MP. However it comes with HD video recording and geo tagging. The front facing camera for selfies is 1.3MP.
Under the hood, the Samsung tabs run on Android v4.4.2 KitKat.
It features a powerful 1.2Ghz processor that’s up to speed on most smartphone related tasks with 1.5GB RAM and a memory slot that can take up to 32GB external memory.
The 4000mAH battery is a beast and promises 22 hours talktime. It’s a non removable battery though.
Even though neither tabs support cellular connection, they support Wi-Fi 802.11 a/b/g/n, dual-band, Wi-Fi Direct, Wi-Fi hotspot.
On to the rooting guide.
Samsung devices used to be very easy to root. So much so that developers started buying Samsung devices because of it.
It’s not that easy anymore. Primarily because of Knox. Knox is a sort of root counter. So no matter how you root, once Knox is tripped Sammy would know that you rooted your device and essentially it’s a game over as far as warranty is concerned.
But luckily Knox is not enforced everywhere yet. So we find that these 7 inch tablet devices from Samsung do not have any Knox security enabled.
That means it’s a boon for us as we can root very easily and also unroot in case we need to go back to Samsung for warranty.
So are you excited to finally root your tablet? This guide here, tells you exactly how to go about it! So why wait? Hop on to the ride!
