Two cheap 7 “Android tablets tested

2013

The tablet market has grown explosively in recent years. Before the introduction of the iPad, there was a small number of Windows tablets available, which were mainly used. In business After the introduction of the iPad soon followed many Android tablets and especially in the low end, the range has grown significantly in the past year.

Recently saw us all that you can purchase for an amount between 150 and 200 euros a great 7 “tablet but what about if you screw even further down the budget? In this review we take a look at it. before we take the Slate 7 HP under the microscope, which can be. purchased for less than 150 euro We also look at the Iconia Tab B1 Acer, which cost around one hundred euro. There are also a lot of tablets to get lesser known brands and you can import from Asia tablets, but tablets of major brands have their advantages in terms of availability and service.

Both tablets we take a closer have a 7 “screen, run Android and are relatively inexpensive that they do not offer the same experience as an expensive model, we know in advance, but how well -. Or bad – these tablets or ? HP Slate 7Appearance and housing

That both tablets are in different price ranges there is immediately apparent. The housing of the Slate 7 feels pretty sturdy, and also close all cracks and crevices fairly well. The back is matte gray with a shiny HP logo that is on top of the housing. At the top left is a camera and Beats Audio logo gives a red accent. With 365 grams, the Slate 7 on the heavy side for a 7 “tablet, but not so heavy that it’s distracting.

The housing of the B1 is from a much lower quality. The plastic back feels very vulnerable and cheap and the finish is not to write home about. You feel that the whole falls apart if you drop it. The B1 is in addition capable of thicker than the Slate 7. Where you have the idea to the Slate 7 that somewhere in the development process a designer has been involved in the B1 is that not the case.

Both tablets are equipped with a micro-SD slot so can be. Storage capacity increases Charging and connecting to a computer is through a standard micro-USB connector. The B1 is the micro sd slot hidden behind a small cover, while it is at the top of the Slate tablet to find 7 back.

In use is that the buttons on the Slate 7 feel a lot better than the B1. Acer actually makes use of whole flat buttons showing small increases again. These nodules do not feel too comfortable, and because the buttons also give little feedback, they are not pleasant to use. The Slate 7, by contrast, firm buttons with clear feedback.

In terms of audio quality are both tablets little impression. HP chose to place the speakers on the bottom will not be blocked if the tablet is on his back, but has the effect it does have the sound clearly from one side comes when you watch a movie. The sound quality is tinny, but the volume is decent.

The B1 has the speaker on the back and if you put down the tablet, it is thus blocked, the not too jofele sound quality deteriorates.

With tablets like the Slate 7 and Iconia B1 should be cut on all matters, including the system on a chip. In these tablets so you do not have powerful quad cores, but more modest chips from the previous generation. The Slate 7 refers to the Rockchip RK3066 of B1 and is equipped with a 8317T-soc of MediaTek.

Rockchip 3066 The two houses RK3066 Cortex A9 processor cores at 1.6 GHz and a Mali-400 GPU. Thus, the chip resembles Samsung’s Exynos 4410, which was later used in the two year old Galaxy S II. The MediaTek 8317T also has two Cortex A9 processor cores, but at 1.2 GHz. The GPU is the ancient of PowerVR SGX531, which is from 2006. Both are no high flyer, but you can not expect in this class.

MediaTek In practice it is important to note that you have to deal with old hardware. B1 at the most The tablet is quite slow and rarely run smooth transitions and animations. In addition, you now and then have patience when starting or switching between apps. If you do not have too high expectations, the B1 still suitable to browse a little and simple games sometimes run too, but there is not intensive to work with. Disturbing is that he higher than 1280×720 pixels does not support video files with resolutions, so you may need to convert new material.

The Slate 7 is in terms of performance clearly of a different class. While the processor cores are not so much faster than those in the B1, the effect of the faster GPU and the double amount of memory very noticeable. The tablet works fairly smoothly, still not as smooth as a model that costs 100 euros more, but it is a big difference with the B1.

For fans of hard data we have some of our usual benchmarks unleashed on the two tablets. For comparison we took some other small and cheap Android tablets. Most of them are, however, just in a higher price range than the two models in this review.

Bench with Ande we tested the raw power of the two cores. Which is not terribly far apart and that is also in line with expectations, since both chips use the Cortex A9 design. Interestingly, the Slate 7 thanks to its higher clock speed is faster when running native code, but lose that advantage when running Java code. The graphs clearly show that these two tablets on field performance laggards are.

With GFXBench we looked finally to the power of the GPU and it can be seen. Differences That the Iconia B1’s PowerVR SGX531 dates from 2006, is painfully obvious here. In this modern benchmark the Mali-400 GPU runs from 7 Slate circles around him. Fortunately, many mobile games smart enough to scale on slow hardware. Graphics settings That means that some games on the B1 still run, but they look or a lot less beautiful than on fast hardware. Image Quality

Both the B1 and the Slate 7 has a 7 “screen with a resolution of 1024×600 pixels. This not such a sharp image, but at this price it is unreasonable to expect a higher resolution. From experience we know that the display one of the items on which at most cheap tablets cutbacks and the B1 is certainly the case.

First the screen rather far sunk into the casing, leaving a lot of empty space between the LCD and the outer glass layer is. Located This provides additional reflections. The viewing angles are not good. On the picture below you can see the B1 and Slate 7, tilted at an angle of 30 degrees. When tn panel in the B1 there is little about the colors.

Viewing angles of the Iconia B1 (top) and Slate 7 (below)

Also, if you look straight ahead to the B1, the color reproduction is not good. We can even say that we have never encountered a screen with such a poor color reproduction, white looks like blue and not just a little bit. A neutral display with white really looks like white, has a color temperature of 6504 Kelvin. Almost no screen gets that in practice, but most screens are still somewhere between 5500 and 7500 Kelvin. In the B1, however, was registered our meter Kelvin and a color temperature of 27,000 that is clearly visible. With the naked eye

Beeldverhouding HP Slate 7 versus Iconia B1 The screen of the B1 is downright bad, at all levels. The Slate 7 is doing a lot better. The backlight is brighter, the viewing angles are better and the color reproduction is in a different league than the B1. However, the display of the 7 Slate has a large defect, which we can reconcile difficult, the aspect ratio is not correct.

The screen of virtually all tablets with a resolution of 1024×600 pixels is 16:10, but HP packed the pixels in a display with a 16:9 aspect ratio. The reason behind this is our totally unclear and the result is simple, everything is stretched. A circle on the screen of the Slate 7 not a circle, but a slight oval and a square is rectangular. The problem can be seen in the above image of the button in Android that leads to the app list properly. The court is of the Iconia B1 and around, as it should. On the Slate 7, the round button slightly oval, as you can see. Left in the picture

Is this a problem? It will not stand in your way in daily use, the functionality is not affected, and therefore there are solid people who are not heavy to lift. We think it is simply not. If you look at pictures of friends or family, it will look weird and most of it is not necessary. How this was ever approved by management at HP, is a mystery.

With the backlight on full power the B1 achieves a brightness of 193 cd / m², which is not much. The 7 Slate does it with 378 cd / m² a lot better. The B1 is just a little better at displaying black so the contrast is higher. That may be the low brightness, poor viewing angles and color reproduction lousy not make it up.

Figure below shows the values ​​of the two tablets again when it comes to color reproduction and color balance. The B1 shows that the white point of the walk has gone towards blue well.

The batteries in both the B1 and 7 Slate with capacity of 10WH respectively and 13.4 Wh to the small customer. In comparison, many other 7 “tablets like the Asus MeMO Pad HD 7, have batteries of about 16Wh.

The low capacities translate into practice to excessive battery performance. In our test browsing go both tablets less than five hours and the video test they come slightly further four hours. Of course you can not expect a solid performance for the money, but a MeMO Pad HD 7 is not crazy much more expensive and performs significantly better.
Software

Unlike manufacturers like Samsung and HTC Acer does not have too many changes to Android. There are many apps included, including a file manager, and a cloud storage service, but the interface looks largely out like we used to. In the notification menu are a few buttons added, and given that the B1 runs Android 4.1.2 – where that standard is not – it is a welcome addition. There is also a trial of McAfee present, and thus we immediately think of the bloatware that we are used to laptops. Who do apps are simply takes the Play Store in the rule for viruses, so do not fear a virus and spam scanner seems unnecessary.

Also on the Android Slate 7 is largely inadequate and there are few additional apps preinstalled. In the settings menu, we’ll find a button for Beats Audio back, which can be used for some headphones. Indicated Here the equalizer settings then adjusted. HP also provides an app with which you can send to a compatible printer. Print jobs
