How to distinguish an acer tablet from a fake. How to distinguish an original Samsung tablet from a fake? Programs required for firmware

While counterfeit tablets are becoming more common, we offer several ways to tell the counterfeit from the original.

Recently, there has been an increase in the sale of counterfeit Samsung tablets. How to distinguish a fake from an original? During tablet tests, we examined two fake Samsung Galaxy Note and found many differences, knowing about which will help you not to fall for the bait of scammers.

So, two counterfeits came to us through third hands: the Samsung Galaxy Note 10.1 SM-P600, better known as the Galaxy Note 2014 Edition. The history of acquiring fake tablets from many is about the same: a market, a train station or a street, a bustling atmosphere, a certain person who needs money and does not need a tablet generously offers to buy a tablet from his hands and at a very low price. The purchase is accompanied by a check from Euroset (or another "network") and a warranty card. Moreover, in our case, in addition to charging and a USB adapter, the kit already included a cover with a keyboard in it.

How to distinguish a fake check?

The first thing we noticed was, of course, the checks. At first glance, real checks, upon detailed examination, turn out to be fake. By the way, Euroset checks are most often forged.

We turned to Euroset-Retail LLC for a comment, but they could not tell us anything on the phone and advised us to contact the law enforcement agencies. But in Euroset stores, experienced sellers immediately found many differences between a fake check and the original. According to them, cashier's checks may differ from region to region and from city to city, but regardless of this, each check of the network must contain certain information, which did not appear on fake checks:

- The real check should say Euroset-Retail LLC, not Euroset LLC. You can usually check the true name of the legal entity of a retailer either on their official websites of these retailers, or in sales outlets.

- Also on the real receipt must be the full name of the product. In this case, the fake receipt did not contain the full name of the product (in our case, Samsung Galaxy Note 10.1 N8000 should have been written on the cash register receipt)

- The check must have the serial number of the product (in our case it was not there).

- Seller's full name must be present. The seller's name was not on the counterfeit check.

How to distinguish a fake by the appearance of a device?

- Appearance of the front panel.

Typically, a counterfeit tablet looks different from the original. In our case, both fakes from the front look almost the same: only the fake for the SM-P600 has the logo moved up, like the original, and is applied crookedly, which is even visible to the eye. The fake N8000 has a logo at the bottom, as befits a real Galaxy Note N8000. In our case, it was easy to distinguish a fake by the size of the tablet. The diagonal of the displays of both fakes does not exceed 9 inches, instead of the required 10.1 inches!

- The presence and location of ports and connectors.

Paradoxically, a fake almost always differs from the original in a set of ports. So this time, they were absolutely nothing like what Samsung tablets should have.

The most remarkable, perhaps, is a separate "back" button on the top edge and a separate DC jack for power supply on the right (the charger in the kit had a specific plug, not a Micro-USB plug). Actually, this charger is one of the important indicators of a fake. Many people then go to stores for the same charger from "Samsung tablets" and are sincerely surprised that Samsung does not have and did not have such chargers.

- Rear panel view.

As for the rear panels, the scammers have "confused" something. For some reason, the fake Samsung Galaxy Note 10.1 N8000 has a very cheap leather-styled back panel, while the fake Samsung Galaxy Note 10.1 SM-P600 has a smooth back, when the originals should have the opposite: the real Samsung Galaxy Tab N8000 is smooth at the back, and the Galaxy Note 2014 Edition has a leather-like back. In addition, in both cases, the camera lenses are off-centered rather than centered.

How to distinguish a craft by its filling and functionality?

The third thing that you should also pay attention to is the filling and functionality of the device. Fakes differ from real ones in every possible way. Some things you can easily check:

- Displays. The easiest way to "see" a fake is to turn on the display. Most often, pixels are visible on them, and the colors do not look quite natural. The counterfeit displays are terrible - with a resolution of 800 × 480 pixels, instead of the promised 1280 × 800 on the Samsung Galaxy Note 10.1 N8000 and 2560 × 1600 for the Note 10.1 SM-P600. Not to mention the color rendition and the matrix.

- Battery. If during the 5-minute presentation of the tablet the battery charge sits down by more than 1-2%, then this is most likely not the original. The fake battery runs out pretty quickly, literally in half an hour. In our test of two fake Samsungs, the batteries lost 10% of their charge in 5-7 minutes! Moreover, when charging from the mains, the charger from the kit began to whistle and crack.

- Processor. The counterfeits use ultra-cheap processors from Allwinner (the AnTuTu benchmark identified our tablets as Allwinner-Tablet N8000 and Allwinner-Tablet SM-P600). Processors from this company are very cheap: for example, the "more expensive" Allwinner A33 processor can be bought for $ 4 - you can imagine how much the Allwinner A23 used in these tablets costs.

Benchmarks showed that both devices are weaker than Samsung's flagship smartphone two years ago - Samsung Galaxy S3: one was rated twice as weak, the other about a quarter. Allwinner SM-P600 has almost half a gigabyte of RAM, so it turned out to be stronger, but Allwinner N8000 has only a quarter of GB! Basically, the first Apple iPad had the same amount of RAM, and it sold great, only it was already 4 years ago.

- Cameras. They are very easy to check. To do this, you need to go to the camera settings and see the maximum photo resolution. If you see that the resolution is small, then this is definitely a fake. Both fakes in the Product-test had two cameras each, and both were 0.3 MP!

- GPS receiver. Go to settings and see if GPS can be turned on and if there are any settings for it. Alternatively, try to download any GPS test app such as GPS test. If there is no GPS, then it will be impossible to download applications and a corresponding message will appear stating that GPS is not supported.

Both "our" fake tablets did not have a GPS receiver. It is theoretically possible that there is GPS, but there is no such function in the settings, and it cannot be detected by any navigation programs. True, this is almost unbelievable and tantamount to their absence for most users.

- If the seller (or documentation) claims that the tablet is equipped with a modem, then it must also have an IMEI number. If you can't find it, then ask your salesperson to do it for you. If a tablet equipped with an IMEI modem does not have a number, then most likely you have a fake in your hands.

- Interface. Original Samsung tablets use the proprietary TouchWiz interface. You can tell by eye if you've ever seen a "naked" Android and once held a real Samsung tablet in your hands.

- Instructions for the tablet. You just have to look at it and read a little. In our case, the instructions of both tablets were full of typos (!), The same screenshots from "pure" Android, black and white pictures, an unpresentable font, which is simply incredible for the instructions for a real device from Samsung, in the check of which there are numbers in the range 17- 20 thousand rubles.

- Stylus. The "trick" of the Galaxy Note series tablets is the included stylus, which the counterfeits did not have. It's easy to check - you just need to look at the case.

- Counterfeits cannot be recognized by original programs such as Samsung Kies 3, which is completely unsurprising. Unfortunately, it will be problematic to check in this way in the field.

- Display diagonal. If there is a ruler or a good eye, the deception can be recognized in this way. The diagonal of both fakes does not exceed 9 inches, instead of the required 10.1 inches.

- Built-in memory. The memory can be checked in the tablet settings, but it is safer to connect to a computer and see how much memory is available. Instead of the promised 64 GB of internal memory, one tablet turned out to be 16 GB, on the other 4 GB of memory.

Distinguish a fake with manufacturer support

We contacted the Samsung support chat, but there we were "sent" to law enforcement agencies. Then we called Samsung support at 8-800-555-55-55. There we were told that when buying goods from hands, a person can turn to them and they will be instructed on how to distinguish an original tablet from a fake one in terms of settings. We were also told that fakes differ from the originals in almost everything: from the interface to the types of SIM-cards (the latter is not relevant in our case, since there was simply no SIM-card slot on the fakes). As a rule, each major manufacturer has its own support hotline, which you can turn to for help in such cases.

The considered forgeries are, of course, two special cases and do not pretend to be general. Counterfeits can be different, improve, like counterfeit checks, become more like the real ones. In this case, the easiest way would be to recognize a fake by an incorrect cash register receipt (without the full name of the product and its serial number), low display resolution, presence of a DC power socket, incorrect positioning of cameras and low resolution of photos, and finally, simply by the small size of the tablets. Well, the most important advice that will allow you to avoid problems - do not buy tablets from your hands, no matter how positive and honest the “seller” may seem! Remember: free cheese is only in a mousetrap.

Product-test continues to test tablets in the field. You can find the results of comparative tests of tablets in our rating of tablets, where all popular models are compared with each other in the most important parameters.

When you turn on the tablet, after the Samsung screensaver, the Android sign appears on a green background and nothing else happens, or vice versa - first the Android icon, followed by the "eternal" Samsung.

We enter the firmware mode

To flash the N8000, you need to use the LiveSuit program. The sequence of actions is as follows:

1. Turn off the device. If enabled - press the power button and hold for about 10 seconds;
2. Launch LiveSuit and point it to the required firmware file - the Select Image button. Wait for the file to be processed;
3. Press "Sound +" on the tablet and while holding the button connect to the USB connector;
4. A window will appear with the following suggestion: "Click Yes if you want the firmware to happen with the memory formatting. Click No if you need to update the firmware without formatting (Recommended)";
5. Wait for the flashing process to finish - about 3 minutes. The device will automatically reboot.
6. Select the Russian language in the settings. The default is usually English.

Programs required for firmware

The program itself for the firmware is LiveSuitPack 1.11.

An error occurs in the firmware when using the Play Market "a and you will not be able to download anything. The fact is that the firmware has an old version of the program. Whatever you search on the Internet, download the Google Play Market from our website: Download Google Play Market 8.1. 29.

Counterfeits for popular tablet models appear on sale not much later than the official start of sales. Big brands suffer the most from the actions of such “craftsmen”. Buyers who have received a fake under the guise of the original Samsung GelaxiNout N8000 tablet may be forever disappointed in the brand. What can you do to avoid getting caught by scammers?

The level and quality of counterfeiting is constantly being improved. The first versions of fakes are so crude that even an inexperienced buyer will be able to determine it. All of the following tips are general and will certainly help identify a fake. But keep in mind that you may end up with a fake tablet of the highest quality, and it will take more attention to detail and characteristics to determine its authenticity.

The photo below is an example of an original tablet and a fake. In our case, it is very simple to identify a fake, even in appearance. The size of the tablet does not correspond to reality, the Samsung logo is smaller in size. The diagonal of the display of the counterfeit tablet is about 9 inches. In this case, the diagonal of the original Samsung tablet is 10.1 inches.

The fake, which ended up in our hands, is radically different from the original in the arrangement of ports and connectors. This is clearly visible in the photo below. Any comments are superfluous here.

The charger for this Samsung tablet has a Micro-USB connector. Our fake is equipped with a connector of unknown origin, and this is perfectly visible in the photo of the plug from the charger. When you try to buy such a charger in a store, you will fail, which once again confirms the fake of the tablet as a whole.

The back panel of the branded tablet Samsung GalaxyNoteN8000 with a diagonal of 10.1 inches is smooth. Our fake has it styled like a cheap leather. Here we can see the shift of the camera lens to the corner, while on the original tablet it is located in the center.

After turning on the planet, a fake will allow you to calculate the low quality of the matrix and color rendition, including pixels visible on cheap copies. The display resolution of the original Samsung GelaxiNout tablet is 1280x800 pixels, while the counterfeit has only 800x480.

The counterfeit tablet is powered by the cheapest Chinese Allwinner processor. For example, the most expensive processor from this company costs no more than $ 4. It's not hard to guess what quality our processor has. The original tablet uses Exynos 4412 processors.

The camera is another weak point of any fake. In our case, the manufacturer of the tablet installed a 0.3 megapixel camera in his "work of art".

Also, a fake can be detected by a small amount of built-in memory, the appearance of icons, a desktop, installed applications and similar trifles.

Note N8000. Despite the fact that this model has been on the market for more than 2 years, it continues to be successfully sold. It is its parameters and characteristics that will be considered in this review.

CPU

The heart of this Tablet PC is the Exynos 4412 CPU. This is Samsung's own development. It includes four cores of revision A9, operating at a frequency of 1.3 GHz. It is the combination of these characteristics that allows the Note N8000 to cope with any task without any problems. Again, all the possibilities implemented in the APM architecture successfully function in this silicon crystal. This is disabling unused cores, and lowering the clock frequency of an unused module. All this allows you to significantly save battery life. All in all, an excellent combination of performance and energy efficiency, which is the hallmark of all devices built on the basis of this architecture.

Graphics subsystem

To perform graphic functions, the Mali-400 MP4 adapter is integrated into this device. Of course, at the time of the release of the tablet, it allowed solving all tasks without exception without any problems. But now its processing power is no longer sufficient for demanding applications. The screen resolution is 1280 pixels by 800 pixels. Moreover, its diagonal is 10.1 inches. This is enough for normal and comfortable work, but a certain graininess of the picture will be present. Another disadvantage is the glossy screen finish. All finger touches will be imprinted on it.

A definite plus is the presence of a capacitive sensor, which is characterized by increased sensitivity. Another advantage is support for up to five touches at a time. But now cheaper devices can boast of a similar feature. Despite the presence of certain remarks, the graphics system of the Samsung Galaxy Note N8000 is well balanced, and its capabilities will be sufficient for the needs of most users.

Memory

The memory subsystem is excellent on the Samsung Galaxy Note N8000. Reviews of the satisfied owners of this gadget are another confirmation of this. It has 2 GB of RAM. Now, 2 years later, not every tablet or smartphone is equipped with that much RAM. The built-in memory of 16 GB is enough to store several movies or a library of books. In addition, there is a slot for installing a Micro SD card up to 32 GB. You can also use an OTZ cable to connect an external ordinary flash drive up to 16 GB. In general, the memory subsystem in this case delays by five points out of five possible. Also, it can be quickly increased without problems by connecting an additional memory card or flash drive.

Frame

The strengths of the Samsung Galaxy Note N8000 cannot be attributed. Reviews only confirm this. There are two options for its design - white (for a female audience) and black (more formal). Case material - plastic. It scratches easily, and it is unstable to impacts. Therefore, it is better to immediately buy a cover in the kit that will protect this tablet from damage. A similar situation with the screen. It is made of regular plastic and is also not crack-resistant. So immediately you need to stick on a protective film so as not to scratch or ruin it. These measures will significantly extend the operating time of this device.

Battery

A mediocre battery is installed in the Samsung Galaxy Note N8000. The Chinese version is even worse in this case. The proprietary device uses a 7000 milliampere / hour lithium-ion battery. This capacity is enough for one day of comfortable work. Although with a not very intense load, its charge can be enough for two days. But still not enough for today. Now there are already batteries for 10,000 milliamperes / hour, and this is enough for 3 days of active use. But the Chinese copy has even less - 3000 milliamperes / hour, which is enough for half a day of work. So before buying it is necessary to clarify the modification of the device. In addition, the rest of the technical specifications in the Chinese version are significantly worse than those of the original.

Software

Samsung Galaxy Note N8000 runs on Android operating system with outdated version 4.0.4. This is enough to run most of the proposals. But still, some programs (for example, An-Tu-Tu tester) require version 4.1. Most likely, the system software of this Tablet PC will no longer be updated. Therefore, owners will have to work with what is available. This nuance must be considered before purchasing.

Communications

The Note N8000 is equipped with a rich set of communications. First of all, this is bluetooth (perfect for connecting other mobile devices), Wi-Fi (provides the maximum data exchange speed when connected to the Internet) and a 4G modem. The latter option allows this device to function in any mobile networks that are available today. At the same time, the owner of the tablet is not tied to anything, but can exchange data with the global web in any corner of the world where there is a mobile connection. Also, do not forget that there is the possibility of making calls. True, it is better to talk with headphones. The tablet has a large diagonal, so it is not very convenient to use it for these purposes. Among the wired communication means, there is the possibility of connecting via the YUSB universal serial interface. For navigation, the gadget has integrated transmitters for working with GPS and GLONASS systems. This will allow you to determine your location without any problems. All this is enough to comfortably fill this device with all the necessary information and navigate the area.

Outcomes

In terms of technical specifications and software, the Samsung Galaxy Note N8000 looks flawless. The price is greatly overpriced. Similar tablet PCs from other manufacturers are much cheaper. For example, Lenovo Yoga can be bought significantly cheaper. The device from Samsung costs 450 dollars, while from the Chinese manufacturer a similar device is estimated at 375. From this point of view, the purchase of a device from a Korean manufacturer is not entirely justified.
