Samsung Galaxy Tab 3 won't turn on. The largest tablet in the Tab line

Hello site visitors. Today we’ll talk about another representative of Samsung’s Tab line of tablets. Namely about the Samsung Galaxy Tab 3 tablet.

The main company is the logical completion and addition of each of its lines. And despite the fact that the Note line is more popular than the Tab, it can hardly be called budget, but the differences, if you don’t go into details, are almost unnoticeable.

Samsung tablet

And so we begin to consider the technical part of the review.

Specifications

Despite the fact that most manufacturers have long since crossed the 1280x800 pixel resolution line, this sample, unfortunately, remained with the same parameters. This 10-inch screen is made on a PLS matrix and supports up to 10 touches. The Samsung Galaxy Tab Tablet 3 runs on a dual-core microprocessor with an operating frequency of 1600 MHz; by the way, it has 4 threads and x86 architecture.

The processor comes with 1GB of RAM, so it will be able to handle most modern applications. Depending on the assembly, the device will have 16 or 32 GB of internal memory, and the presence of a slot for external memory will increase the total space by 64 GB.

3G, Wi-Fi, A-GPS, Bluetooth, accelerometer, gyroscope, light sensor and infrared port are all also included in the basic set of the tablet PC. The gadget also has two cameras, rear and front, 1.3 and 3 megapixels, respectively. This Samsung Tab 3 tablet works on average up to 9 hours in offline mode. Its weight was approximately 500 grams, and its dimensions were 243x176x8 millimeters.

After a detailed examination, it was found that the design with some elements is even very similar to the Note line, for example:

1. All functional keys were lowered as mechanical ones to the front panel;
2. Familiar shape of the central button with a mirrored edge;
3. More rounded corners, resembles an oval.

Appearance tablet

Also on the front side you can find a front camera with a light sensor. On back side, just like on the front there is the manufacturer’s company logo and the rear camera peephole.

back side

On the bottom of the Galaxy Tab 3 tablet there is a standard micro-USB, which should please buyers, since the company decided to move away from the original connector to a more standard one.

Bottom edge

Turning the tablet PC over, we discover something surprising, namely the presence of an infrared port, most likely for wireless control, and not for data exchange. There are also two memory card and SIM card slots (micro-SIM), and the standard two volume and power keys.

Top part

The side faces are made almost symmetrically, only the left one has a headset jack. By the way, the speakers with a gray frame look quite stylish. More detailed information can be obtained by typing in a search engine the phrase Samsung Galaxy Tab tablet reviews, where experienced owners will give you comprehensive answers to your questions about this model.

In addition, the placement of the speakers is chosen very well; during operation, they are not covered by anything or anyone, and therefore the sound will be clear and pleasant to hear.

Side edge

In general, everything is good, we have not discovered anything supernova or revolutionary. A little bit of Note, a little bit of Tab, and that’s how this tablet computer came to be. One thing worth mentioning is that the assembly of this Galaxy Tab 3 tablet left only negative impressions. With light pressure or random movement, characteristic creaks are heard, and in some places quite large gaps were found, but one hopes that these shortcomings will be taken into account in mass production models.

Setting up Wi-Fi and 3G

It’s worth focusing a little on Android OS version 4.2

Desktop

As you can see, the main panel has changed its location; it is now located at the top of the screen.

Notification window

This is what the notification window looks like, as we can see it has a sufficient selection of shortcuts, for example:

1. Wi-Fi connection;
2. Enable mobile data;
3. Turning on Bluetooth and more.

Infrared program

This is actually the program for remote control via infrared.

Wi-Fi setup

As in any other version, we switch the Samsung Galaxy Tab Tablet 3 slider to operating mode and wait for the list of available connections to appear in the right window, for example:

1. Protected points;
2. Open points.

Enter the password and use it within range.

3G settings

To set up 3G Internet, first insert the card into the slot with the gadget turned off; the reverse spring mechanism will help you.

Next, go to Settings/Advanced settings/mobile network, turn on mobile data transfer and then go to Access points, click functions and create a new connection point. Now we fill in the fields with the relevant information.

Data to fill in the fields

The name of the new Samsung tab tablet connection point can be anything.

1. MTS - internet.mts.ru;
2. for BeeLine - internet.beeline.ru (if a USB modem is used, then home.beeline.ru);
3. Megafon - internet;
4. for tele2 - internet.tele2.ru.

Username

• MTS - mts;
• for BeeLine - beeline;
• Megaphone - empty field;
• tele2 – empty field.

• MTS - mts;
• BeeLine - beeline;
• Megaphone - not required;
• for tele2 - not required.

You can also send an SMS to the corresponding number of your operator, just like on a phone, and receive automatic settings. We looked at the Samsung Galaxy Tab tablet, instructions for setting up the Internet, let's proceed to the firmware.

Getting Recovery and Root

First of all, we save all the necessary information on other media, since everything will be deleted.

Now it’s worth noting right away that everything you do with the tablet is done at your own peril and risk, no one gives a 100% guarantee that the device will work after that. Therefore, you should not make claims to the site administrator for your crooked hands and lack of understanding of serious things.

And so we download the KIES program to install all the necessary drivers and remove it from the PC. Now we download the Odin program, as well as Recovery, Root and firmware from the website 4pda.ru or from official sources.

Instructions

• Turn off the Samsung Galaxy Tab 3 tablet and press the power button and volume minus;
• Connect the device to the computer;
• We run the program as an administrator - this is very important;
• The device will appear in the program under the corresponding COM port.

• By checking the boxes in the picture above;
• Press the PDA button and select the file with Recovery;
• Press the START button;
• The word PASS will indicate that the process has completed;

To obtain root rights, turn on the tablet PC and place the archive with the previously downloaded rights in the root of the memory.

Now go to Recover, press power and volume minus. Select Install from sd card and find your archive, confirm its choice and wait until the firmware is installed. Well, as practice shows, typing samsung galaxy tab tablet reviews into a search engine, I advise experienced users to resort to such methods in extreme cases.

OS firmware

The firmware can also be done using the Odin program; follow the same sequence of clicks. You will receive an updated operating system to Android 4.2.2. If obtaining superuser rights is also problematic for you, use this program.

But as mentioned earlier, only you and no one else are fully responsible for all consequences.

Problems during operation

1. The tablet does not see the SIM card;
You need to check its functionality on another device; if everything is fine, the problem is in the modules - take it for repair. If not, then most likely you cut the SIM card incorrectly or took it out of the plastic incorrectly.
2. The tablet gets very hot;
The OS may not be working correctly, reset all settings to factory settings - everything will be deleted. In general, heating during operation is a common phenomenon in equipment.

3. Does not turn on / does not charge / does not connect to the PC;

Immediately take the device to certified repair centers.

4. The tablet does not see external devices, For example;

• Keyboards;
• Mice;
• Flash drives;
• Modems.

This is because this model does not support the host operating mode at the hardware level.

The review article has come to its logical end. Now we recommend that you watch detailed Samsung Galaxy Tab tablet videos on testing and review.

Full video review

High-tech tablets produced by modern manufacturing companies have long become absolutely indispensable assistants for many users. In most cases, this “indispensability” becomes the main cause of annoyance and disappointment when devices fail. Fortunately, there are ways independent decision one of the most common causes of device malfunction, which we will consider using the example of a Samsung tablet Galaxy Tab 3. So, based on statistical data and the experience of leading employees of service centers, we can confidently say that the main reasons why the gadget does not charge and does not turn on are:

• Battery completely discharged;
• Burning of the power chip;
• Charger malfunction;
• Damage to the power connector;

Now that we have learned the most common causes of malfunctions, let's consider simple and effective ways their elimination. Let’s immediately make a reservation that if the recommended actions are unsuccessful, we can say with 100% confidence that the problem is in the device itself, which must be taken to a Samsung service center for diagnostics.

TOP 4 most popular reasons for Samsung Galaxy Tab 3 dysfunction

1 place

Almost all device owners sooner or later face the problem of complete discharge, in which connecting the charger turns out to be useless, since the only way out of this situation is to connect the tablet to the network, but not through a computer, and wait a few minutes. There is a possibility that as the minimum charge accumulates, the indicator will light up and the device can be fully charged. If this does not happen, most likely the problem is in the charger itself, which needs to be replaced with a similar model.

2nd place

In second place on the list of the most popular reasons for refusal to turn on and charge is an ordinary charging fault. It is obvious that if you are careless and violate the rules for using the charger, it will soon fail and will need to be replaced. You can determine if the charging is working properly by simply trying to charge it using a computer. A lit indicator is a sure sign of a charger failure. At the same time, you need to understand that if the tablet is completely discharged, using the computer is useless. In this state of affairs, the only thing correct solution - urgent repairs in a professional workshop or service center.

3rd place

The next failure, no less common than other types of failures, is a burnt-out power chip. It should be noted that most often the microcircuit burns out due to the destructive effects external factors, the main one being power surges. You can eliminate the possibility of breakdown as a result of such circumstances only by purchasing specialized protective devices, which do not always justify the money spent on their purchase.

4th place

And in conclusion, I would like to draw the readers’ attention to such a standard problem as a breakdown of the power connector, which is often caused by negligence in the rules for using the charger, the use of third-party products and wear and tear. Of course, the easiest way to solve this problem is to replace the connector, which, by the way, is much cheaper than repairs.
