In the low-cost area we must forget to enter the “K” war, because those resolutions involve more expensive (and more demanding) panels. We could not expect a 4K or even a 2K here, but what we have in Fire 7 are 1,024 x 600 pixels and this is “short”, at least as far as experience (not cost, of course).
Leaving aside the resolution, the panel balances colors and contrast very well, without being too saturated and with a good white temperature (we do not have the numerical data, but it is quite neutral). The maximum brightness is more than enough for abundant light situations and the automatic brightness setting works very well.
What is excessive is the Blue Shade mode, although this also concerns the setting by the system (see also in Amazon Fire HD 8). It is an option to attenuate the intensity of the so-called blue light, which normally applies a very warm filter, but in this case is a much-exaggerated dye that greatly worsens the experience, far from contributing to read better with low light. It has an adjustment, but only affects the tone (red to orange) and not the intensity, which would be correct.
Otherwise, (except the pixels per inch) the screen is fine, with good viewing angle. The glass is thicker and you can see a certain distance with the touch panel, but it is something that we notice if we look a lot at angles and does not affect the experience, in fact the tactile sensitivity is correct (although we will see when talking about the performance that the Taps sometimes play it).
Performance: the secret of (little) RAM
We have the same processor in both Fire 7 and HD 8, an evolution of the previous that stays in a Quad core to 1.3 GHz. Although in the tab of the official page does not have more data on the interiors, Using third-party apps (CPU-Z, which fortunately has Fire OS version) we can see that it is ARM Cortex-A7 architecture and it is accompanied by a Mali-450 MP graphics and 1 GB of RAM.
Is this enough to have a good experience on a tablet of just over 50 euros? It is, because at this price we can not expect what SOCs or somewhat higher configurations yield, but we can not expect the same as in HD 8 although it may seem to us according to the specifications. We have a relatively lag expected for this, but sometimes it is quite flashy, for example when opening Twitter, Amazon Music (here it may take us more than 3 seconds to upload, being own) or the camera.
We can also find some hitch when deploying notifications curtain or timeline type apps like Instagram, but this is much more anecdotal. And obviously we will notice it when loading video games, but the truth is that beyond some break in the configurations (i.e., the previous to the games itself), the performance is quite good considering the features.
However, what can penalize the experience is a direct consequence of adjusting both the resources: delay the tactile response (when it is not a panel) or the accelerometer, for example when playing Asphalt 8. The delay of the execution of the tap we notice it for example when closing relatively heavy applications like a game or Spotify.
And another consequence is the heating, which starts very early without even playing, concentrating in the upper part of the back towards the corner of the camera, although it takes little to cool and does not bother exaggeratedly (it is enough to vary a Little grip if we are in landscape mode).
In what is system navigation and transitions we do not experience lag, we have a good experience here and when launching multitasking. And the screen flip does not suffer a break either (and we see that the accelerometer works well, since it is quite sensitive and does not require too much inclination to rotate screen).
The multimedia experience: we are better at reading
Amazon has its own multimedia content with Music and Video and in the app store we find some of the popular streaming services like Spotify or Netflix, but the low cost here happens. We have already talked about the resolution and here miracles can not wait (you can expect what marks the price), but the sound is quite poor in quality when we turn to the speaker.
Loudspeaker that is covered almost completely if we support the tablet on its back side, and that forces us to support it on the screen if we do not want the volume to be reduced. It is also better not to resort to the maximum volume (we speak about 97 decibels) and stay a little less than half, or directly opt for headphones since the experience improves a lot.
Of course, except for the lag that exists when browsing the heaviest apps (especially Amazon Music and Spotify), there are no interruptions in what is the reproduction of content, neither audio nor video, even if we set the highest possible quality. Moreover, when playing video the tablet is not only heated.
The cameras that are not missing, although we do not expect miracles
Having smartphones, tablets are not always the first camera that we use, but using this device can arise the need and at least these usually incorporate a back. In this case, we have two, a back of 2 megapixels and a front VGA, that is, practically the most basic.
The quality is quite low, but if we are not demanding, in this sense, we will manage and the one that includes frontal camera will allow making videoconferences. We have pictures with very little detail and watercolors, and with medium or interior light it is better that we aim at a static lens, since having a slow shot (especially activating the HDR) is quite possible that we get blurry photos.
The interface is simple and quite intuitive, and allows both cameras to pan or “lenticular”, which is similar to Apple Live Photos or create GIFs by joining multiple shots (captured as small video or multiple shot). Of course, the app takes a couple of seconds to load and opening from the home screen by dragging from the corner is slow and fails pretty much (we have to drag very slowly and for a long time).
Autonomy: there is no fast charge, but each load
We do not know the mill amperes / hour data and the system does not provide any statistics, so in this section we leave empiricism aside to be merely “experiential”. The Fire has standard USB 2.0, nothing of type-C or 3.0, and with its 5.0 volt charger takes about 3:17 hours to charge (0 to 100%).
Autonomy will always depend on what use we make, but making it quite intense (playing music, multimedia content, games and social networks) lasts for more than a day. We talked about 4 hours of playback with Amazon Video, around an hour of gameplay, about two hours of music playback and punctual reviews of social networks, when it has been somewhat less intense we have remained around 30% battery after 24 hours (without putting it in airplane mode during the night).
