To use your Galaxy S9 smartphone comfortably, it is important that it holds a charge for a long time and performs its functions properly. If the battery life is reduced, and the device itself fails under high loads, a new battery should be installed.
For self-installation, you must have additional tools, which I will describe in this manual. Also, you need to prepare the workplace – it must be well lit and free of dust.
It is important to understand that without the appropriate skills, it can be difficult to repair. This instruction is of a recommendatory nature and does not induce action.
The time it took me to replace was about 60 minutes.
Tools to be used:
- Flat master keys;
- Hair dryer;
- Capacity for storing screws;
- Plastic tear-off tool;
- Phillips screwdriver 1.5 mm (Phillips PH00);
- Scotch tape (in the absence of it on the part itself).
- Well myself battery for Samsung Galaxy s9 (Battery marking EB-BG960ABE).
STEP 1 – Turn off your smartphone
- Hold the power button until the screen displays “Power off”. Click Turn Off.
- Be sure to wait for the screen to turn off.
STEP 2 – Remove the back cover
To remove it, we need a hairdryer, since the heated glue will be easier to loosen. In addition to a hair dryer, you will need a suction cup and flat tools – Openers.
- We heat the upper corner of the lid, from which we begin to detach the lid. Install a suction cup on this edge.
- Carefully insert the Opener between the lid and the frame and pull on the suction cup.
- Next, we heat the next area and, in turn, insert the openers into the slots, passing them along the edge to loosen the glue.
- On the bottom edge of the smartphone, the adhesive is particularly strong and may take longer to heat up with a hairdryer.
- Important! Removing the cover is the longest process, so don’t be afraid to spend more time on it than you planned. Remember that the back cover is fragile and may break. If difficulties arise, heat the place again.
As soon as the back panel around the entire perimeter is peeled off, you need to slightly lift it to disable the fingerprint sensor.
STEP 3 – Disable the fingerprint sensor
- Carefully lift the cover and use a spudger to remove the sensor.
- After that, you can completely remove the back panel and set it aside.
STEP 4 – Unscrew the screws, remove the motherboard cover
Prepare the place where you will store the screws, as there are 2 types of screws in different lengths in this smartphone. If you have difficulty unscrewing it, use tweezers. We recommend remembering the unscrewing sequence.
- Remove the screws marked in the image with red rectangles and set them aside.
- Next, slightly lift the cover of the motherboard with the NFC tag and remove it. It snaps off from above.
STEP 5 – Disconnect the battery
- After removing the motherboard protection, we can get to the battery cable. The connector is marked in the photo with a red rectangle.
- Disconnect the connector with a plastic spatula to avoid short circuits during repair.
STEP 6 – Unscrew the speaker screws and remove it
Also prepare a place to store the screws.
- Remove the screws marked in the image with red rectangles and set aside.
- Gently lift the speaker with tweezers, then remove it and set it aside as well.
STEP 7 – Removing the battery
Here you need a flat and not sharp tool, since the battery is glued to the body. Important! Do not damage the motherboard or other components while working.
- Insert the tool from the side between the housing and the battery. Lift it up slowly to loosen the glue.
- Then repeat the process on all sides.
- Once you are sure that the glue is loose everywhere, carefully remove the battery from the case. Set it aside to prepare for disposal later.
STEP 8 – Prepare and install a new battery
- Remove the protective tape from the tape on the new battery. (If your part does not have adhesive tape, you need to place it on the battery yourself.)
- Insert the battery into the case. It should be of a clear fit and not difficult to install.
- Gently press down on the battery while pressing it against the body so that the glue sets better.
STEP 9 – Putting the smartphone together, putting everything back in place
- Place the speaker back on the board with the charging connector and tighten with the screws. Make sure it snaps into place at the bottom.
- Connect the battery connector.
- Replace the protective cover on the motherboard. Make sure that it snaps into place and tighten the screws in the same sequence as you unscrewed.
- Next, reconnect the fingerprint sensor. Bring the cover to the body of the smartphone as close as possible and carefully connect the sensor.
STEP 10 – Installing the back cover back
If the panel was deformed due to swelling of the battery or broke during repairs, install a new one. back cover for samsung. Since any defect can lead to further breakdown of the insides.
- We prepare the surface of the lid for glue application. Degrease with alcohol.
- Before installing the cover, make sure that the glue is evenly applied, remove the excess.
- Next, holding the cover exactly over the smartphone, press it.
- Heat the seams with a hair dryer to loosen the glue.
- Press down on the back panel with your fingers until the glue cools down.
Now Samsung Galaxy S9 is ready to go again! I turn it on, run a performance check.
Tesla’s autopilot is to blame for the deaths of two people: is it true or not?
In April 2021, a terrible accident occurred in the US state of Texas. A Tesla car with two passengers flew off the highway at high speed, crashed into a tree and began to burn. It took the firefighters 4 hours and more than 120 thousand liters of water to put out the fire. Subsequently, the burnt bodies of two men were found inside the car: the first was sitting in the front passenger seat, and the second – in the back. Before the trip, they told their wives that they wanted to ride the car and mentioned the autopilot system. There was really no one in the driver’s seat, so the media began to write that the accident was the fault of Tesla’s automatic driving system. Our editorial staff immediately had a question: how could the autopilot system be turned on if no one was driving? After all, Tesla cars carefully ensure that while driving on autopilot, a person sits in the driver’s seat and holds on to the steering wheel. A very mysterious story has happened – now I will tell you everything that is known at the moment.
Tesla crash in Texas
The fatal accident occurred on April 18 and became known about it thanks to The Verge… Two elderly men from the Texas city of Spring got into a car that did not fit into a turn and crashed into a tree. The police said that at the time of the accident, there was definitely no one in the driver’s seat. It has been argued that Tesla’s autopilot is to blame for the deaths of the men. Many people easily believed it, but the owners of electric cars from Elon Musk strongly disagreed with the police version.
The fact is that Tesla cars carefully ensure that the driver always sits behind the wheel and watches the road. If the driver’s seat does not feel the weight of a person in the driver’s seat, his face is not in the camera view and no one is holding the steering wheel – the autopilot simply does not work. All this is done because the system still cannot fully control the vehicle and must be constantly monitored. Tesla’s autopilot can only follow a given lane, park on its own, keep its distance from other cars and avoid collisions. In any dangerous situation, the driver must take control.
How to trick Tesla’s autopilot?
However, Tesla’s autopilot can be easily fooled. One of the popular hackers recently said that the system starts working if a photo of the driver is hung in front of the camera inside the car. Even if the image does not move, the software thinks that the person is watching the road closely. The hand tracking feature can be fooled by simply stuffing a large orange into the steering wheel. And the pressure sensors on the driver’s seat are simply turned off when deceived by the methods mentioned above.
Apparently, it was these tricks that were used by people who posted provocative videos with Tesla cars. In 2018, a man was stripped of his license for sitting in a passenger seat with his arms thrown back behind his head while driving an electric car. And in 2020, the blogger lay down to rest in the back seat while the car was driving on autopilot. True, it did not last long.
How safe is Tesla autopilot?
The accident in Texas is shrouded in mystery. Not only that, the Tesla car could not go on autopilot while the driver was in the passenger seat. Elon Musk generally said that the owner of the electric car did not buy the Full Self Driving feature, which costs $ 10,000. So at the moment it is impossible to answer exactly what happened on the Texas road. We could assume that the men were simply cheating on Tesla’s security system and resting in the passenger seats. But this is impossible if there was simply no autopilot in the car.
The fatal accident happened at a very inopportune time for Tesla. Many regulators began to seriously question the company’s autopilot safety. In March, the NHTSA began investigating 23 accidents involving Tesla vehicles that may have been the autopilot’s fault. There have been seven fatal accidents in the manufacturer’s vehicles in the past 5 years, with the autopilot system being blamed most.
In 2016, Tesla representatives boasted that their cars drove about 210 million kilometers with the autopilot on. In comparison, ordinary cars kill people every 97 million kilometers of total mileage. In 2017, the NHTSA administration confirmed this data – according to statistics, in Tesla cars with the autopilot on, airbags are deployed 40% less often. From this we can conclude that vehicles with an autopilot are safer than with manual driving. But it is too early to draw hasty conclusions and it is better to wait for the results of new investigations. In the aftermath of the April accident, such cases will clearly be closely scrutinized.
Most accidents in Tesla cars are people’s fault. The company is trying in every way to make sure that drivers follow the road even when the autopilot is on. But no – people want to outsmart technology and relax behind the wheel. In 2018, a Tesla car drove into a concrete divider and caught fire, after which the driver died in hospital. The investigation revealed that during the accident, the owner’s hands were not on the steering wheel and his attention was clearly directed to the smartphone. In 2016, another person crashed in a Tesla car – it turned out that in 37 minutes of the trip he held the steering wheel for only 25 seconds.
Finally, it is worth noting that the problem with Tesla cars is not only the autopilot. The company uses lithium-ion batteries for power supply, which can explode and burn from a strong shock even in the absence of oxygen. It took firefighters about 4 hours to put out a car in Texas. To do this, they had to call Tesla and consult with the company’s specialists.
The microchip will detect COVID-19. Chipping started?
The COVID-19 pandemic continues to march across the planet. According to official data, an average of 8 thousand cases of coronavirus infection are recorded in our country per day, and the first place in the world in terms of the number of infected, according to Johns Hopkins University, is still occupied by the United States with more than 30 million confirmed cases. The fight against the pandemic is also in full swing – mass vaccinations have been deployed in more than 140 countries around the world. However, according to experts, due to the unfair distribution of vaccines in developing countries, it is possible to expect a victory over the virus no earlier than 2023. But do not forget that another effective way to combat infectious (and not only) diseases is their early detection. Recently, scientists from the United States have developed a medical microchip that, when implanted under the skin, can detect SARS-CoV-2 in the body in a matter of minutes.
Microchip for detecting COVID-19
As with other infectious diseases, the best way to stop the spread of COVID-19 is to detect the infection early. This means that in our time, we must be aware of any symptoms that may appear over time. But not everyone can recognize the symptoms when they appear. And, as we all know, failure to do so can lead to the transmission and spread of the virus.
But that could change with a new medical microchip developed by the Defense Advanced Research Projects Agency (DARPA), a military laboratory unit operating under the US Department of Defense. Designed for subcutaneous implantation, microchip can detect COVID-19 in the bloodstream for a few minutes.
When implanted, the microchip will also be able to display chemical reactions in the body, which signals the “user” that symptoms of COVID-19 will appear the next day. Researchers at DARPA have worked for years on ways to prevent transmission of infections and fight pandemics, according to a published report.
Their job was shown in the show “60 Minutes” on the American television channel CBS on April 11. The microchip, which reportedly does not track movement, sits in a tissue-like gel and is designed to test the patient’s blood, “writes Britain’s The Independent.
Interestingly, the microchip itself is in a green tissue-like gel and, when implanted, can display chemical reactions in the body, which signals the “user” about the impending symptoms of the disease (which, as a rule, appear the next day).
Where and how to use the microchip?
In fact, medical microchips have been (and have been used) for quite some time. For example, back in 2004, the US Food and Drug Administration (FDA) approved a radio frequency identification (RFID) device called VeriChip, which allowed doctors to view a patient’s medical records for quick and efficient evaluation. Over the years, many implantable microchips for various medical purposes, for example, for the delivery of various types of drugs.
FDA Approval VeriChip met tough opposition, but in the following years, many implantable microchips have been developed for various medical purposes, such as delivering various types of drugs (including birth control) and even microchips that help monitor heart health. And speaking of new developments, DARPA also recently invented a special filter that can be attached to a dialysis machine and literally remove COVID-19 from the blood of critically ill patients.
Once the chip sends you a “signal”, you can check yourself for COVID-19. “It’s like a check engine light,” the developers note, explaining that anyone using the new technology will immediately receive a kind of signal that prompts them to conduct a COVID-19 test on their own.
And, of course, it should be noted – before you start building any conspiracy theories, just know that these chips that detect COVID-19 will not be able to track movement or location. By the way, recently we talked in detail about why Bill Gates is not going to massively chip the population of the Earth and does not want to end up “killing all people”.
It is noteworthy that the new microchip may well be used by American sailors, especially after the incident associated with the outbreak of COVID-19 aboard the aircraft carrier Theodore Roosevelt, as a result of which 1,271 crew members tested positive.
Physicists have invented a way to detect dark matter
Our Universe is formed by something that you and I cannot directly observe. This mysterious substance, called dark matter, fills 85% of the universe and is responsible for its structure and the arrangement of galaxies and stars. Since dark matter does not interact with light, but has weight, it can only be measured indirectly – dark matter bends the light of stars due to the gravitational effect, just as glass refracts light. Is it any wonder that this mysterious substance has puzzled scientists for decades. But science does not stand still, and the latest research in the field of quantum technologies may turn out to be a vital link in unraveling the mystery of dark matter. Recently, a collaboration of US researchers has developed new devices using quantum computing bits that can detect weak signals from any of the subatomic particles. The new method, physicists believe, will search for evidence of the existence of dark matter 1000 times faster than ever.
While the rovers fly across the Red Planet, the world of physics is literally shaken by scientific discoveries. Recently, researchers at Fermilab reported a discovery that contradicts the Standard Model, a theoretical construct that describes the electromagnetic, weak, and strong interactions of all elementary particles. According to the results obtained, muons – they were found in cosmic rays – deflect when passing through a magnetic field, which contradicts theory and may be a sign of the existence of a force of nature unknown to science.
At the same time, scientists from the Budapest-Marseille-Wuppertal Collaboration applied a new method for calculating the interaction of muons with magnetic fields. Their results, oddly enough, confirmed the inviolability of the Standard Model and if they turn out to be correct, then there is no discrepancy between theory and experiment, which means there is no new force of nature.
It is important to note that the studies described above are far from the only ones in this area. For example, earlier results obtained at the Large Hadron Collider (LHC) at CERN also indicate the possible existence of new physics, and Danish scientists recently questioned the existence of dark energy, a force believed to be responsible for the expansion of the Universe.
Today physicists themselves cannot say anything definite (especially about the collapse of the Standard Model), since all the results obtained will need to be double-checked. This process, according to scientists, can take a year or a year and a half. As the physicist Andrei Golutvin, who works at the Large Hadron Collider, said in an interview with Tass.Nauka, “during this time the existence of the“ new physics ”will either be confirmed or denied”.
In the meantime, scientists are working to verify the results, physicists from the University of Chicago seem to have found a clue to the mystery of dark matter, which – and this is the most interesting – is associated with the results obtained at Fermilab.
How to detect dark matter?
Direct detection of dark matter particles has eluded scientists for decades, but not because of a lack of effort. Experiments on Earth were aimed at searching for a strange substance with the help of the LHC, but space seems to be conducting its own experiments – astronomers (provided they know where to look) can already detect the signature of dark matter today. This can be done using unusual X-rays from galaxies (when dark matter particles decay), strange flashes of light or X-rays near neutron stars (when dark matter particles turn into photons in their powerful magnetic fields). But there is also another way.
It was recently demonstrated by a team of researchers from the University of Chicago and the US Department of Energy’s Fermi National Accelerator Laboratory, developing new devices capable of detecting weak signals from any of the subatomic particles – “axion” and “hidden photon” – they were thought to interact with photons or light particles. in the visible everyday universe.
The theoretical existence of axions was proposed more than 30 years ago, but it was not possible to detect them experimentally. The new technology, according to scientists, is capable of radically advancing scientific research in the study of dark matter. Read the text of the study published in the journal Physical Review Letters. here…
“We know that there is a huge amount of mass around us, which does not consist of the same material as you and I,” – said Aaron Chow, a Fermilab physicist and co-author of the new study, told New Atlas. “The nature of dark matter is truly an insurmountable mystery that many of us are trying to unravel.”
Qubits and dark matter
It should be noted that in the last decade, scientists have improved their ability to use the properties of quantum mechanics that govern the strange behavior of particles on the smallest scales of the universe. Advances in this area have led to technology such as the “qubit” or bit of quantum computing. Qubits are inexpressibly sensitive to the slightest disturbance in the environment. And this (as you might have guessed) is exactly what physicists need to detect dark matter.
The new technique uses qubits to detect photons generated when dark matter particles strike an electromagnetic field. A special device, the so-called superconducting resonator, offers a way to create and store a signal photon: as soon as the photon is there, a qubit is inserted into the cavity and collects data about it. This method is most likely to help detect dark matter, since any invisible particlethat converts to photons can be seen. So you and I will have to wait again, but only this time in anticipation.
