Comparison Blackview Tab 8 128 GB vs Oscal Pad 70 128 GB

The maximum brightness in nits provided by the tablet screen.

The brighter the display, the more readable the picture remains on it under intense ambient light. Also, high brightness is important for the correct display of HDR content. However, a large margin for this indicator affects the cost and power consumption of the screen. Manufacturers can specify standard, maximum, and peak brightness values. At the same time, an equal sign cannot be put between the maximum and peak brightness. The first indicates the ability of the screen to produce the specified brightness over its entire area, while the peak one - in a limited area and for a short time (mainly for HDR content).

The resolution and maximum frame rate provided by the main camera when recording Full HD (1080p) video at normal speed, without slow motion (if available).

The standard resolution for this format is 1920x1080. Note that this can be either the maximum shooting resolution or one of the relatively simple options in addition to more advanced standards (such as UltraHD 4K). At the same time, Full HD is considered more than a decent resolution by modern standards, and at the same time, it can be supported even by fairly simple and inexpensive tablets.

As for the frame rate, there are actually two values in normal shooting - Full HD 30 fps and Full HD 60 fps. A higher frame rate allows you to achieve very smooth display of dynamic scenes - even fast-moving objects in the frame are seen as clearly as possible, with almost no blurring. However, the low shooting speed also has its advantages - it allows you to reduce the amount of material being shot. Therefore, tablets that support 60 fps may have the ability to reduce the frame rate to 30 fps. But speeds above 60 fps are already used for shooting slow-motion video (slow-mo); see "Slow-mo" for more on this.

The ability to reproduce full stereo sound through the tablet's own speakers. For this task there must be at least two speakers. This complicates the design and increases its cost, but has a positive effect on sound quality: the sound is more expressive and detailed than when using a single speaker, it has a surround effect, as well as higher volume.

At the same time, for better sound quality, the tablet can be equipped with advanced sound system, which are noticeably superior in quality to conventional speakers. Such information further emphasizes the high level of the device. At the same time, the characteristics usually do not give the full name of the speaker system, but only the name of the brand that had a hand in tuning the sound.

The power at which the tablet is charged in normal mode.

On the practical side, the higher the charging power, the less time spent on it (with the same battery capacity). But this parameter does not directly affect compatibility with chargers: modern devices are able to work with “chargers” of both higher and lower power. At the same time, in the first case, the battery controller will automatically limit the charging current, and in the second, charging will simply take more time. Accordingly, the standard charger may be of less power. And when looking for a third-party charger, you should focus on the allowable charging power indicated in the specifications — this will give the maximum guarantee against malfunctions.

The presence of a case that protects the device during storage and transportation. Complete covers can have a different design; one of the most popular options is an accessory with a folding flip that covers the screen, while in some cases the flip can be folded into a stand. However, many users prefer to buy cases at their own discretion, without relying on the choice of the manufacturer, so this configuration option is not particularly popular.

The tablet case is protected from shocks and falls. A characteristic feature of devices with shock protection is a durable, massive body, often with a bumper made of elastic material at the ends. The degree of shock resistance may vary, but even the most modest models, as a rule, can easily withstand a fall from a height of about 1 m; More detailed information should be found in the manufacturer's documentation. Note that the presence of shock protection significantly affects the cost, and for everyday use, a protective case for a regular tablet is usually sufficient. So, first of all, those who constantly find themselves in conditions with an increased risk of “accidents” should pay attention to impact-resistant models: builders, rescuers, military personnel, etc.

It is not uncommon for such tablets to additionally have the MIL-STD-810 protection standard. Initially, this is a set of specifications that establishes certain levels of protection of electrical equipment from environmental factors. The standard was developed to test military equipment for the US Army to ensure that it remains operational under a variety of adverse conditions. It imposes quite stringent requirements on the test subjects: the level of resistance of the product to impacts during falls and shakes is checked, vibration tests are carried out, the operation of the device is tested in a wide temperature range, in the rain, in fo...g, under the influence of sand, dust, etc. However, the MIL-STD-810 label in “civilian” products does not always mean the highest degree of protection. This is due to the lack of strict regulation of testing. Thus, the most cunning vendors test the gadgets being tested according to literally one or two points of the program from an extensive list and often deliberately do not disclose which tests were passed. Accordingly, the specific features of such protection remain reliably unknown. The standard has been in force since 1962. Each new version of it is indicated by a letter of the Latin alphabet at the end. The further the letter in the alphabet, the more modern the version of the certificate. Since 2008, the MIL-STD-810G specification has been in force everywhere, and in 2019 a new edition of the MIL-STD-810H standard was approved.

The main material used for the body of the tablet.

— Plastic. Plastic enclosures are inexpensive, light in weight, and provide enough strength for everyday use. It is also worth noting that there are many varieties of this material, and the quality of the plastic used for the body usually directly depends on the price category of the tablet. Of the unequivocal disadvantages of this option, low scratch resistance can be called; in addition, if the plastic is glossy, prints and stains instantly appear on it.

— Metal. Most often, in tablet cases, metal refers to aluminium alloy. One of the key advantages of this material is durability. In addition, the metal resists scratches very well and gives the device solidity — both in appearance and in the feel in the hands. It weighs a little more than plastic, but often it is this moment that provides the mentioned solidity. The unequivocal disadvantage of metal cases is a rather high cost.

— Glass. Usually, in this case, it means a back panel made of special high-strength glass, complemented by a metal frame at the ends. Such materials look very good and feel good in the hand, but they are not cheap. In addition, glass, even tempered glass, does not withstand impact well and can crack if dropped or otherwise “trouble” (although the impact still needs to be quite strong for this). Therefore, this option is found only in some top-class models.
