More necessarily a luxury accessory, the tablet has almost become a commodity so the prices do not stop falling. The class of devices under 100 € was sometimes surprising thanks to products of rare quality. The Polaroid Infinite 7 inches is not one of those …

Face to face
A long time standard bearer for instant cameras, the Polaroid brand has expanded in recent years into the mobile accessories market with the help of white label products and then its own brand. The Infinite 7 inch tablet is part of this effort of diversification and the device comes to hunt on the ground of the ultra-low-cost with its price floor of 50 €.
In the bowels of the device, there is a dual-core AllWinner A23 processor clocked at 1.54 GHz, with 512 MB of RAM and a Mali-400 MP graphics chip. The 7-inch (17.8 cm diagonal) TN slab touch screen displays a glorious 800 x 480 px resolution; the unique VGA front camera captures snapshots of 0.3 million pixels; the internal memory ranges from 4 to 8 GB depending on the model (expandable via microSD up to 32 GB additional). You have to rely on Android 4.4 KitKat to turn everything and autonomy is provided by a 2400 mAh battery.
The 4 GB version is from € 49.90, when the version 8 GB, decorated with 3G, displays a price of around one hundred euros.
If it is obvious that at this price we should not expect a device made of “noble” materials, we could still hope to find a plastic of better quality. The shell of the tablet is of fairly coarse quality, the assembly leaves a yawn both at the screen and the battery and is conducive to squeaks. In addition, the back of the tablet is easily scratched and attracts stains.
Where most 7-inch devices opt for physical buttons on the side edge of the device, so they fall naturally under the fingers – this format is used mostly in portrait mode, vertically – the tablet of Polaroid makes the strange choice to place all controls on the top edge, including volume control, thus forcing some finger gymnastics or two-handed use. Buttons that, by the way, do not really breathe quality and click with a sound rather dry and very plastic.
The overweight of the tablet (a little more than one centimeter thick) at least lends him the advantage of marrying the hand thanks to his bulging back. That’s at least that.
The slab of the Polaroid Infinite 7 has almost all the defects that a screen can accumulate. First of all the definition of 800 x 480 px displays a very low density of 120 pixels per inch and the place occupied by the display is only 63% of the front panel. The maximum brightness reaches a starved maximum of 170 cd / m², the color rendition is completely distorted, since the delta E reaches 12 and the color temperature even explodes the terminals of our probe and becomes at the limit of the computable (more than 55,000 K). Contrast does not save the game, with a low average rate of 411: 1.
Side delay and afterglow, the screen of the Infinite 7 delivers respectively 127 ms and 33 ms, results are not very good, but not catastrophic. If the numbers are staggering, in use it is not that which hinders the most. The two problems that most plague this tablet are primarily the construction of the device and the technology of the screen. First, the plastic slab that covers the whole is very far from the screen, which handicaps the responsiveness and promotes glare; the use of a TN panel has the effect of drastically reducing the viewing angles, making the tablet sometimes painful to use so it must be tilted to see something over the navigation.
INTERFACE AND NAVIGATION 2/5
In the great unhappy tradition of low-cost devices , the Polaroid Infinite comes pre-loaded with a version of Android (4.4) outdated and with little hope of updating. Fortunately, the manufacturer has had the good taste of practically not making any changes to the “stock” interface of Android, which ensures a good general fluidity during navigation.
In fact, the only significant change is in the navigation bar. Where we usually find the Back, Home and Multitask buttons, the manufacturer has thought fit to add two controls to manage the sound and a shortcut dedicated only to the screenshot. All are not only redundant with physical buttons and can not be removed, but also overload the navigation bar.
While we have not noticed any really slow-downs, it is rather the poor screen definition, the poor information density that results and the reduced viewing angles of the TN panel that make all the navigation activities (Web, app, photo …) painful. At least, the empty space between the shell and the circuit effectively dissipates heat since the tablet does not heat under any circumstances.
Video playback goes directly through the Google Gallery app, which is relatively limited in functionality. However, the tablet has no trouble decoding HD or Full HD video, but because of its low screen definition, it is far from honoring them.
Hi point on the side of the headphone output. Only compatible with 3.5mm jack 3 points, the output delivers a power below average and is not even saved by its rendition, nasal. As for the speaker, it is also severely lacking in power and gives a muffled sound focused on the mediums.
Side video games, the slate does not really work wonders. Where the majority of tablets manage to launch most games in the Play Store at the cost of a loss of graphics, the Polaroid crashes just and constantly during the launch of Real Racing 3 , for example. Once a less demanding game launched, the slate still has trouble following both the graphics as the general fluidity since there are perpetual micro-jerks that make the game somewhat complex.
The unique 0.3 Mpx sensor on the front panel announces very quickly the color: it will be dull. The rendering does not really shine by its deep colors or its vibrant details, but is enough to ensure video conferencing as the brightness is lenient. In use, still count nearly 2 s between the action and the effective triggering of a photo.
The Polaroid tablet does not hold the day, no matter what. Difficult to digest such a defect while today expects a tablet that it takes at least 2 days of sustained use. Unfortunately, the battery literally melts at a glance since a short surf session (just over 30 minutes) sees the battery percentage plummet a good fifteen points. Autonomy collapses rapidly below the 50% threshold.
We must strangely about 4 hours to fully recharge the meager battery of 2400 mAh. If the first half of the gauge is charging rather quickly (about as fast as it runs out), you have to be patient to reach 100%.
