Wizard Notes. How to open your Galaxy

In the Комментарии и мнения владельцев to many previous smartphone repair articles, you’ve asked about how to disassemble Samsung‘s waterproof Galaxy S series smartphones to replace the back cover, and how difficult it is. Today I will try to describe this process in detail, with an indication of the nuances and possible pitfalls that can occur during disassembly.

Given the abundance of glass in the design of modern phones, the most common reason for disassembly is not the need to repair electronics, and the banal replacement of the back cover, which often breaks when you drop the phone.

Looking ahead, I can reassure Galaxy S7/8/9 owners that even with a broken back cover and broken display protective glass, your phone is likely to remain water resistant due to the presence of a laminating film on the inside of the glass. This is clearly visible after removing this very cover. The film is surprisingly strong, and even the shards of broken glass can rarely damage the film. This is a very big advantage of Samsung phones.

If, however, you need to replace the back cover, you need to choose a new. So we will not start with the disassembly itself, but with the choice of the back cover, which can be very different quality, ranging from very inexpensive plastic and ending with a very expensive 100% original.

The easiest way to buy the original cover is to find an ad on Avito or Jule with the sale of your required model for dismantling. In this case you will get a second-hand but original cover, which will be of a better quality than the similar ones. How much it might cost, it’s hard to say. It depends on the appetite of the seller. Approximately for such a cover are asked from 500 to 1 000

Another option is to order it on the Internet marketplaces like AliExpress or eBay. In the first case you are likely to receive an analogue which can range from excellent to terrible. With eBay it is better to look at lots of sellers who are in the USA, but then you will need to use an intermediary, which will increase the cost of the purchase. On the average it will be kept within 1,000-1,500

You can buy it in a “store around the corner” for 300-500. The advantage of such a purchase is the ability to assess the quality and appearance before giving the money. The minus is that it is likely to turn out to be the same Chinese spare part.

Another, most uneconomical option is to buy the original from an authorized service center (if they sell it). The cost of this pleasure can go up to 3 500-4 500 If you’re a pektsionist, this is your option.

After we bought the spare part, it’s time to disassemble our patient.

  • Plastic plugs. Guitar picks or even a thick plastic package from something will work just fine for this role
  • The suction cup. It is very desirable to have it for this purpose. Even an ordinary suction cup will do
  • Wide tape
  • Medical or isopropyl alcohol. A syringe or a jar with a spout as a reservoir. I’m more comfortable using the hydrogen peroxide jar specifically, as it’s easier to control the dose
  • An ordinary household hair dryer as a tool for heating. By the way, instead of a hair dryer you can use a canvas bag filled with salt preheated in a pan to 90 degrees. This option is preferable to a hair dryer, as it will allow you to heat the smartphone better and more evenly, and thus more soften the adhesive tape that holds the cover.
  • Construction gloves to protect your hands from burns (the phone will be hot).

When you are all set, it is time to get started.

First, you need to roll the broken back cover in duct tape. This is to prevent shards of glass from getting on your fingers and flying into your eyes when you disassemble it.

If you are not disassembling the phone to replace the cover and the cover is intact at the time of disassembly, you need to glue it all the same. it is not guaranteed that you will be able to open the phone without cracking the cover.

Please note that you should tape the lid as carefully as possible, preferably without bubbles, and most importantly, without jams and joints. Otherwise the suction cup will not stick to the cover and it will be harder to open the phone.

Then we warm up phone with a hair dryer or a bag with warmed up salt.

When the phone is warmed up (so that you can hardly touch it with your bare hand) glue the suction cup closer to one of the bottom corners.

Then we drop alcohol in a joint of a cover and a case and we begin for a sucker to pull away a cover, simultaneously trying to stick in a slot between a cover and a case a mediator or a plastic strip.

If you are opening the whole cover you have to be very careful at this stage and not try to poke the plectrum too deeply as the tension is too high and the cover can easily burst.

Never use a metal tool for this purpose, otherwise you are almost hundred percent likely to crack the cover.

The most important thing is to achieve a small gap between the cover and the case. This may require several approaches of warming up, dripping alcohol, and pulling the lid off by the suction cup. If the cover is already broken and the purpose of disassembly is its replacement, then you do not need to worry. pull harder and try to stick the pick inside.

The alcohol in this case is needed to make the tape come off the surfaces more easily. Also the alcohol won’t let the scotch go back on. Do not pour too much, but do not worry too much either. the alcohol will not harm the phone’s insides. Optimal dosage is three/five big drops per joint.

Once the lid is ajar, keep dripping alcohol into the joint and go all around the perimeter, peeling off the tape. Take your time and don’t forget to warm the cover where you peel it off.

Important nuance. don’t stick the connector deep inside in the middle of the right edge. There are outer coils of the wireless charging coil very close to the edge and there is a danger of damaging them.

Note, except for the tape around the perimeter, there are sticky white seals inside the lid, which must be kept. Once you have removed the old cover you need to carefully glue the gaskets either to the new cover or to the inside of the phone in the same position as on the old cover. This will prevent the new cover from bending and will make the construction more assembled and tight.

Then you need to remove the lens and sensor covers from the old cover.

The glass is in an aluminum frame that bends very easily, so before you remove it, heat it up well and remove it carefully. This frame is glued to a ring of duct tape on a tight base.

It is best to use a thin flat tool to remove it. I use a blade.

On the new cover, it’s best to glue this frame with adhesive to keep it watertight. For example, with a B7000.

Once you have the new cover ready to install, it’s time to clean up. Namely, clean the perimeter of the metal frame from the remains of the adhesive tape on which you will glue the new cover. Cotton swabs and rubbing alcohol will help. Slowly clean the frame, making sure it is absolutely clean, without any lumps of old glue and tape. It is especially important if you want to keep watertight.

If water protection is not important, then we take the lid, align it relatively to the body and, gently pressing around the perimeter, glue it in place.

If you need to restore the protection from water, then, in addition to the tape, which is likely to be on the new cover, you will need to glue the perimeter of the cover with glue or sealant. I advise glue, because the sealant in a confined space without oxygen will dry very long.

After the cover is glued, you need to put it under the grip for a couple of hours. Do not overdo it. A big book is enough.

That’s all, our phone is ready. It remains to remove from a table, and it is possible to use an updating.

In this case I purposely showed as an example an inexpensive Chinese cover, which you can buy in most spare parts stores, and which with a high probability will come to you from AliExpress. The difference in color with the original is striking.

So it is worth to think whether such a variant will suit you. If it does not suit you, it is worth looking for other options, about which I wrote in the beginning.

Pay attention to the color of the tape in the original and in the Chinese. This is the easiest way to distinguish the original from the fake. in the original scotch tape is a thick white tape with neat edges. If the tape is a different color, you are facing a fake or a counterfeit, which can also be good, but less often.

As you can see, if you are not in a hurry, then with the proper skill and patience opening of such a device is not difficult and fascinating case that you can do at home.

How to open the back panel on the Samsung Galaxy S7 Edge

Let’s look at an example of how to open the non-removable back covers on the smartphone Galaxy S7 Edge specialists. It is much easier to do when you have special equipment for this. It resembles a normal vise, equipped with a large suction cup.

It serves as a tool to hold the back of the housing. You do not need a heat gun with this equipment. As it refers to the methods that have some risk of breaking the Samsung high temperature.

  • In the middle is a recess for your phone. The case is placed between the two rubber vise holders;
  • The cover of the fixture closes and the suction cup engages. It is attached to the back cover of your Samsung smartphone. The joints should be moistened with alcohol or an alcohol-containing solution;

Eventually, the glue between the parts of the case succumbs and the device is disassembled into two main parts. the back cover and the module of the Samsung cell phone.

On the top end, to the right of the micro-USB connector you will see a small notch that looks like it was made for you to pry the cover open. Carefully insert your fingernail into this notch and swipe it to the left, passing over the part where the plastic case fits tightly to the display glass of the smartphone.

Preparing before disassembling a smartphone

Unfortunately, the times of removable covers of smartphones are left far behind with bare hands there is not a solution. Therefore, before the disassembly itself, it is worth to have the necessary equipment.

First, we need a special spatula to open the cover. Lately sellers of spare parts for smartphones (however for almost any small equipment) put in the set of their products the necessary small tools more and more often. If you decided to replace, for example, the battery and bought it, say, on AliExpress, there is a good chance that the seller has already put the necessary tool inside the package in which your battery will arrive.

Secondly, for deeper disassembly of the smartphone (if you have to go further than removing the cover) you will need special small tools a set of screwdrivers and tweezers. Well, and, lastly, do not forget to prepare a paper clip for removal of a tray under the SIM-card tray it is necessary to pull out before performance of any manipulations.

On its top end, to the right of the micro-USB connector you will see a small notch, as if designed to allow the cover to be picked up. Carefully insert your fingernail into this notch and swipe it to the left, passing over the part where the plastic case is tight against the display glass of the smartphone.

The glass back cover is glued to the frame of the phone. Using a suction cup pull the back cover up. Warm up the device in advance with a hot air dryer. This way the glue will soften and it will be easier to open the back cover.

Necessary tools

Ensure you have the right tools before disassembling your Samsung phone.

  • Mediator or regular credit card. Also bonus cards from small thickness stores will do.
  • PH Phillips screwdriver. If you only need to remove the lid. this tool may not be necessary, but for the removal of the chip and other modules such a screwdriver is required.

Older Samsung models usually have a removable back cover, but in the Galaxy line of recent years, you can find non-detachable cases.
