Samsung Galaxy Tab 7.7 LTE I815 Specs
Earlier, there are 3 tablets from Samsung that i just showed you in my previous reviews.

And those are Samsung Galaxy Tab 4 – from the smallest 7-inch model to the largest 10.1-inch variant.

From what i’ve seen on all these 3 tablets, it’s safe to say that 2 of these tablets – the ones with Snapdragon 400 processor (8-inch and 10.1-inch models) – can be great as gaming tablets, if not the best.

And that’s thanks to their Snapdragon 400 processor and Adreno 305 that really help a lot in their gaming performance, especially in handling 3D graphics intense games like Asphalt 8: Airborne, Modern Combat 4 or N.O.V.A 3.

And that’s the fourth-gen edition of Samsung’s most popular tablet series on the market.

What about the other edition of this tablet family?

Well.. well.. well.. as many of you know already – on this website, i already showed you many of Samsung GALAXY Tab series – the Tab 3 series, the Tab 4 (which i just published recently) and even Samsung GALAXY Tab 2 (even though i haven’t reviewed all models in this tablet generation).

However, there is still one generation of Samsung Galaxy Tab series that i haven’t managed or had time to review on this website.

And that is the first-gen Samsung Galaxy Tab.

So that’s why, today, i want to flashback our memory again by reviewing the first edition of this tablet series.

But i’m gonna start today with the 7.7-inch model of Samsung Galaxy Tab, the LTE version.

And probably the other variants of this series – like the 8.9-inch or other bigger models (if there’s any) in my next reviews.

Well, if you’re interested to know much more about this tablet, then here you go, my personal review of Samsung Galaxy Tab 7.7 LTE.

But i’ll probably not talk a lot about the entire thing of this tablet.

In this review, i’m gonna put the priority mostly on its gaming performance and the elements that have something to do with it – like display resolution, processor, GPU, RAM and battery life.

Of course, other sectors like camera or UI will probably get some space in this review (who knows?).

So you might want to check out this entire review!

Okay then, without further ado, here you go, my personal review of Samsung Galaxy Tab 7.7 LTE.


The first time Samsung launched its Android tablet, not many people considered it as a real challenger for the Apple’s iPad.

The most complaints that Samsung received over its first-ever GALAXY tablet were: their horrible build quality, ugly designs, laggy performance and other sectors that are just not on par with Apple’s offering – the iPad, which used to be the ‘definite choice’ for tablet shoppers out there who wanted to get premium tablets that didn’t compromise quality and performance.

But impressively, it didn’t take such a long time until Samsung finally found the best formula to make tablets that could compete with Apple’s tablet.

Soon after launching some sub-par mediocre quality tablets under the flag Samsung Galaxy Tab series, this Koren-based manufacturer finally had something that was worth considering for tablet shoppers out there on the market – besides the iPad.

Samsung Galaxy Tab 7.7 LTE was one of Samsung’s OG (older gen) tablets that indeed could finally meet with the needs of most tablet users out there who demand a good media-consumption tablet.

To be perfectly honest, I’m actually quite impressed with the whole thing that being offered by Samsung on this tablet.

First of all, it’s powered by a dual-core processor made by Samsung – Samsung Exynos 4210 -, coupled with Mali-400 GPU and 1GB of RAM.

And as i’ve always said over and over again on this website – any tablet that is powered by Mali-400 GPU will have good gaming performance, if not great.

And the gaming performance of these Mali-400 tablets are mostly good, with games like Modern Combat 4, Asphalt 8: Airborne, Dead Trigger 2 or N.O.V.A 3 all running smoothly in medium to highest graphics setting.

So this kind of makes me think that, despite being an older-gen tablet, it’s really amazing that Samsung Galaxy Tab 7.7 LTE indeed can be a pretty good gaming tablet.

And i’m basing this opinion from what i’ve seen on many Mali-400-powered tablets like Samsung Galaxy Tab 3 8.0, Archos GamePad 2 and even the lowest-end budget cheap Acer Iconia Tab B1-720 tablet, which all have good gaming performance, if not great.

But the questions are, with all of this set of great hardware specs, does Samsung Galaxy Tab 7.7 have what it takes to compete with other 7 to 8-inch tablets on the market to date, especially in mid-end market?

Is it worth it to buy this tablet, especially given the fact that this tablet is older-gen tablet released a few years ago?

If there is one sector that makes me impressed a bit about this tablet, then is definitely its specs.

Samsung Galaxy Tab 7.7 LTE comes with:
- a 7.7-inch display sporting the resolution of 1280x800 pixels or known today as 720p resolution,
- a dual-core Samsung Exynos 4210 processor clocked at 1.4GHz per core,
- 1GB of RAM, Mali-400 GPU (which takes huge role in ensuring its good gaming performance),
- 3.15MP camera on the back that is accompanied with LED flash and autofocus,
- 2MP camera on the front,
- 5100mAh power battery inside,
- Android 3.2 Honeycomb out of the box,
- 16GB/32GB of internal storage with the expandable external storage with microSD card for up to 32GB
- and some other standard features.


In the sector of screen, it’s amazing to see such an older-gen device like this already comes with a 720p display. I know that most of 2012-released tablets already adopt this type of display.

However, given that this tablet used to be in the first-generation series of Samsung Galaxy Tab, it really makes this 720p display look good for an older-gen tablet like this.

But that’s on paper.

In terms of quality, the display of this tablet might not deliver such an eye-pleasing experience just like any other 7-inch or 8-inch rivals that already sport 1080p resolution display.

However, it still looks pretty sharp for a 7.7-inch tablet and everything that you throw on this tablet can still be seen or read nicely – although you probably will still need to do some pinch-to-zoom gesture, especially when browsing the web or reading books.

One thing that really impresses me a lot with this tablet is definitely its hardware specs.

To be perfectly honest – as one of the tablets in the first-gen series of Samsung Galaxy Tab, i didn’t expect this tablet to have such powerful hardware specs on it (of course, in 2012).

Having a Samsung dual-core Exynos 4212 processor with the clock speed of 1.4GHz per core, Mali-400 GPU and 1GB of RAM, means that this tablet will be more than good to handle most of the games – even the graphically demanding ones – that you see today on the Google Play Store.

As a matter of fact, i’ve already seen many Mali-400-powered tablets - like Archos GamePad 2, Samsung Galaxy Tab 3 8.0 or even the budget cheap Acer Iconia Tab B1-720 -, amazingly have great gaming performance – with games like Modern Combat 4, Need for Speed and even Asphalt 8: Airborne running smoothly in medium to highest graphics setting.

And that’s actually not really surprising for me given that Mali-400 is still a powerful GPU until today – although it’s not relevant anymore with today’s standards.

So if Samsung Galaxy Tab 7.7 LTE is already considered as a good gaming tablet, then it’s no brainer that this tablet will also be great or even more than great (or greater) to do any basic tasks that you’ll mostly throw on this tablet every day – like watching movies, checking emails, using live wallpaper, browsing the web or any other media-consumption tasks. It delivers a smooth performance and excellent experience to the users.


Similar just like most of the tablets under the flag Samsung Galaxy Tab, this 7.7-inch tablet still features the same 3.15MP camera on the back and 1.3MP camera on the front, plus with the addition of LED flash and autofocus on the back camera.

Given that this tablet was released back then in 2012 (Q3 to be more precisely), then its quality or the photos/videos taken with the camera on this tablet might not deliver the best looking quality just like the newer Samsung Galaxy Tab tablets even with the same 3.15MP camera.

But at least, it still works and gets the job done, plus the photos probably are still worth showing off to your Instagram or Twitter followers.

Battery Life

Interestingly, this tablet is powered by a 5100mAh power battery, which is much bigger than the battery capacity inside the 8-inch model of latest-gen Samsung Galaxy Tab 4 – with its 4450mAh battery.

This is actually weird because as a normal user, we probably assume that a tablet with bigger screen will need much bigger battery, right?

Well, apparently, Samsung has been doing such a great job in improving all of its technology and power saving management for its latest-gen tablets, not to mention, making some tweaks here and there on the software as well.

And that’s why Samsung now doesn’t need to cram such a huge battery capacity in its devices just to make them last longer in battery life.

Thanks to Samsung’s innovations and improvements on its technology, now having a much longer battery life even with a smaller battery capacity is possible.

Anyway, back to the Samsung Galaxy Tab 7.7 LTE. In terms of battery life, this tablet is still good in that department.

So if you are a moderate user and are gonna use this tablet mostly to do some basic tasks – with screen on/off combined -, then you can expect to use this tablet last in one solid day – of course, in one full charge.

However, if you’re a hardcore user or tablet gamer, and will mostly use this tablet to do some heavy intense tasks – like for watching HD movies in marathon or playing games in the row, then you will likely need to bring your charger anywhere around you because it probably could only last around 5 to 7 hours the most, which is still pretty good for a 7-inch tablet.

My Personal Opinions

In conclusion, despite being an older-gen tablet – i still think that Samsung Galaxy Tab 7.7 LTE is still a good media-consumption tablet.

And that’s thanks to its Samsung Exynos 4212 dual-core processor, 1GB of RAM and the most importantly, the Mali-400 GPU. With this type of specs, this tablet will also be good – if not great – as a gaming tablet.

As i mentioned already above, with these specs, even the newer games like Asphalt 8, Modern Combat 4 or Need for Speed Most Wanted will run in medium to high graphics setting.

And that’s pretty cool for a tablet released in 2012 like this one.

Meanwhile, for other sectors outside performance and gaming performance, this tablet is pretty much good for doing some other things – like checking emails, watching HD movies, browsing the web (especially with LTE enabled, damn, it’ll be fast man!), reading books, listening to music or many other media-consumption stuff.

So the decision is now yours to make.

Are you willing to buy this older-gen outdated tablet or otherwise, you want to get a much better choice at the same price point with this tablet?

Well, if you do, then i have some great recommendations for you in 7-inch tablet market – like LG G Pad 8.3, Google Nexus 7 (2013 edition), Kindle Fire HDX 7, HP Slate 7 Extreme, HP Slate 7 Plus, Samsung Galaxy Tab 4 8.0 or even the most advanced tablet on the planet right now, the Xiaomi Mi Pad with NVIDIA’s latest and greatest Tegra K1 (with 192-core GPU).

Well, if you ask me, i probably will go with the Xiaomi Mi Pad given its most powerful Tegra K1 processor.

And the best thing about this tablet is, it’s really affordable compared to other 8-inch tablets out there, priced at just $240 for the 16GB storage and $270 for the biggest 64GB of internal storage, not to mention, with microSD card slot for up to 128GB for both models.
