You are respected and loved Mr, and it can't just be me, and it's not just for this subject, it's for everything you ever put out. God bless you Mr. I can take anything you say as the reality . which is rare for youtube
Sorin this is a nice workshop for phone repairs.
I thank you for the update and I learned again
hi sorin , i advice you to use money rubber to scour the screen in there place until the adhesive hardness , i work in phone repair and find its the best way to do that without damaging the new screen , this method will not put high pressure on the screen and you can give the phone to the customer without need to wait the adhesive hardness (if he cant wait) , hope these make your work more easier
Thanks for all the effort you put into teaching in these videos. You are a very good teacher.
I absolutely LOVE that you upload this often now!
What do you mean ?
hi Sorin excellent video did not realized you had to reheat the phone , thanks you i'm on a steep learning curve ,love the hot glue
I would cover the cracked glass with sticky tape before removing it.
Sorin your video goes to new level. No dogie job. Video edited. You deserve All the best for you.
Hello and thanks for your videos. I’ve been a consumer repair tech for many years on & off. Must say I’m impressed with your troubleshooting & repair abilities. I love the tools you used in this phone video, esp the usb charge monitor tool you are using. Unfortunately it shows as non-available as well as the thermal camera. I didn’t however see the thermal camera used in this video, but I can think of many uses for such a device. Thank you, have a great day. 🙂👍
Well done sorin nice fix mate
I love your new content. Much more professional, but I also was enjoying the "dodgy Sorin". :D
thanks sorin, i'm following for years now and i'm a professional tech also. i hope your own business will make you a lot happier and maybe more calm in your everyday life (just in a positive manner). deep love and nice tech utlities btw.!
Thank you Sorin. God bless you!
I enjoyed your tuitorial so much keep up 🤗
Thank you for sharing knowlege.
Salut ,Sorine! Te urmaresc de ceva vreme, i-mi plac vlogurile tale cu reparatii, sunt net superioare altor vloguri. Esti un om minunat! Totusi , am o nelamurire. Cum poti lucra electronica cu manusi in mana?! Fie ele si chirurgicale. Este obligatoriu in UK sau ....
Dokładnie. Zawsze wymieniam tylko to co jest uszkodzone i zostawiam oryginalne części, zwłaszcza body
Nice to see you are wearing the antistatic gloves, join the club.
You Are Superman💪
Repairing without schematics😁
No, the 2.7A at 5V is actually correct, if you account for thermal loses and the 0.2A from the resistance drop it comes down to basic Apple like 5v 2.4V (it just triggers the DCP at 5V 2.4A), the only reason the you see we see 2.7A its because of the losses and the fact that the battery is heavily discharged as well, it's just triggered another charging protocol as a fallback because that charger doesn't support QC2 which is the S9+ officially supports.
PD (USB i mean), PD MTK and or QC2 MTK Or just QC2 is another combination of protocols some from MediaTek and Qualcomm by using the PD standard over it.
My Poco F1 for example can trigger a variety of modes PD v2.0 at 18 watt at 9V and 2A but also a 6.9V decreasing as the battery charges down to around 5.2V starting from (with thermal loses included) 2.8A as that is slowly decreases to around "0mA" when it reaches 100%,
I have a lot and very high quality of chargers (the original which triggers the last one) who support most of the charging protocols which are out there and have tested this and also at work with like all the Galaxy A and S family(both Exynos and Snapdragon variants), all of the Xiaomi, Notes, Pocos etc etc and the normal ones or Pros or whatever, even the HUAWEI ones.
The Xiaomi ones usually trigger the PD MTK or MTK or QC2 fast charging protocol the rest are on either Samsungs AFC or SFC which is basically a QC2 copy at 9V 2A or rarely the PD v2 or just the DCP at various Ampere values but always 5V.
Charging protocols are a mess to deal with...
Edit: We use the exact same pad for heating phones at the store i work. This is basically a universal standard at this point.
I understand your point but, this not a standard, usb-c was accepted as a standard but each manufacturer modified the communication protocol so now we have a bunch of standards and protocols. This was the idea, one charger for everything :D
@@electronicsrepairschool USB-C is the connector, not the stuff that goes through it. The voltage, amps, comms, etc are part of the thing that goes through it, be it USB 1, 2, 3, PD, BC or QC.
The point of the USB-C is to be insertable a lot, stiffen the connection, make it reversible, faster and increase the power delivery, but there has to be room for improvement while the connector stays, so the protocols have been freed as to keep increasing power and speed and to allow for competition between manufacturers while keeping minimum interconnectivity.
Ideally, devices should support as many standards as possible, but what is likely is that they will all support the workhorse 5V 3A that PD allows and not worry about phone model to keep things cheap.
They have achieved what they set out to do. You can charge at any port (up to 15W) and you can also use one of the standards (QC or PD) to go up to 100W.
In the future, however, since USB PD is part of the USB spec and allows up to 100W (Extended to 240W in 2021), it is likely that it will be more widespread. Under the hood, Apple accepts USB PD, Samsung has just put out 45W chargers with USB PD certified (15V 3A), I think we're seeing the emergence of a final standard. It's simpler (5, 9, 12 and 20 volts) and also supports the fine control thing.
It seems that 3A is here to stay. So 5V (15W), 9V (27W) and 15V (45A) are going to be the phone and tablet staple, with the 20V and the higher extended ranges to be used for laptops, replacing the 19V thing they do now.
A used original part is usually better than a new aftermarket part. The same goes for the automotive industry. There are always exceptions, but it is too risky to take the chance.
I wish this video was uploaded before, same story costumer come to fix screen, told me phone need only replace screen, i ordered screen phone doesn't work...only when some preassure is applied on one of spot on the motherboard...
Esagger seems to have good cables... Also Anker and LDNIO
@Electronics Repair School Actually you can get original parts for samsung, just of course not on ebay / aliexpress.. :)
I been watching a lot of videos from this chap and love watching them they are very informative and been very useful
I have dabbled in computer repairs for sometime and done a few basic repairs on mobile phones and tablets but going down to component level I kinda shy away
But seeing these videos has helped a lot in figuring out what may be the problem on certain devices and I'm now considering buying some of the equipment such as scope the hot air soldering kit have a couple laptops sat around for practicing so let's see
In fact I have 2 laptops that need repairing one of them was supposed to be just a reformat but the owner failed to tell me the darn thing doesn't even switch on only has an orange charging light and the other laptop for water damages after roof got blown off during a typhoon and seen at least 3 blown components one actually looks like it melted
Actually I also have an Asus Zenfone that stuck on Asus logo when turning on it won't even flash stock firmware not entirely sure what's up with it if it's a problem with the Emmc as copying the content stops at a certain percentage or if it's down to locked bootloader so any tips on that would help
So more of these videos I shall be watching
I have the same brand of heat mat but I've heard bad things about it like one person said it blew up
agree!original part is the original part.
Thanks thanks sir gerad job.
i love the way you also write" how we are dealing with phone repair" just the way you talk...it's so funny... anyways good job... no insult intended...
I've been unlucky with quality on a few AliExpress orders for screens. I don't bother any more. If screen is broke, time to upgrade whole phone. Phones with good spec are so cheap now.
You do best Jobs from electronic
Sorin what do you think of buying screen and digitizer separately is it easy to remove old lcd screen from old digitizer?
good job my friend two tips use the pad at 95 degrees and second make or buy a phone glue remover tool work smarter not harder
Hi i would have wanted to see how you put the clamps.
What's that battery tester you're using 🤔 can you post link? Thanks!!
Big fan mr sorin
It's working
Thank you for this video, here are my 3 cents to it.
1. Yes, working with original parts is OK, but there are customers who want new parts, not used parts. And if you can't get the original part new, you'll have a trouble with this customer.
2. There are 3 major types of displays, which are incell, soft and hard LCDs. I don't like HARD ones, really easy to damage. A good one incell or soft are my preferences. Incell is the cheapest, but, it comes at the cost. Make a research, you can learn about them :).
3. Apple screens are much cheaper than the rest ;). Worth mentioning though.
4. Yes, you have to remove all the glass, correct, but it doesn't mean you have to use a microscope for it like 100% of the times. You can do it with a magnifying glass as well in many cases IMHO.
5. Good that you've mentioned about the proximity sensor. Ideal would be to mention the location of it. Most of the people won't know the location and won't be bothered to look for it. yes, that's their problem if they'll damage, but, would be nice to add this and make it a complete tutorial :).
6. I'd like to convert one screen to another device. If will do it like ever, will post on this/my youtube channel. But, for now don't have diagrams of screens like LVDS signals, and those additional chips like in Apple and others. I don't have too much spare time as well, so it's a dream more than anything else ;).
As always great vídeo Mr Sorin. Thank you for everything.
Does anyone know the name of Diana's channel? I am trying to find out more about the battery tester. Thank you
It's Didi Tech Girl!
I've always fitted genuine Samsung screens complete with the frame and never had an issue.
What is the battery tester you use for batteries ?
can you give the link for the device you use ? the one were the usb meter plugs in
Hello,from what site you order screen?
pls give information about battery tester sir 😊
There is a previous episode with the review for the baterry tester.
Sa stiti ca in Romania am gasit displayuri originale la anumite magazine online de renume dar de obicei se gasesc cativa ani de la aparitia telefonului. Cand telefonul incepe sa devina destul de vechi nu prea se mai gasesc originalele. Numai bine si mult succes in continuare 😎
Pe care site? Am patit cateva ori ca nu am putut sa pun displayul nou pe telefon atat de rau o fost.
did you make this battery test charger by yourself on EBl charger?
were did you get your gloves from and why do you use them? are they anti-static?
The magic hands!!!
Can you recommend a web site to buy smd components for mobile phones ?
So u saying the 9.2 v on the usb meter is the accurate reading cus it's the standard voltage?
Yes you can buy new original screen with frame with the Samsung seal on it but the cost is almost as a new phone ...
Wear glasses when removing broken glass from devices, that stuff pings off everywhere and can get in your eyes. Any glasses will do but I suppose goggles would be better.
The black B7000 is better than the clear based on my experience but that's my opinion
0:21 ok, tel me how can you work with gloves? I have no idea how to take small screws or to hold something... I just can't
Recent capacity doesn't say anything about battery lasting (life).That's the case of quality and stock storage time.About 3 pieces of battery I replaced in my mobile phone after half year of using until I got propper one.
Show what type of clamps and how please
Sir pls what website or app do u get this Samsung s8 screen and how much u got it?
If you don't have a heat pad, but you do have a 3D printer, then put the phone on the build plate and preheat it to 70-80 degrees Celcius ;)
The whole video i thought, i must have something that will heat up.. oh yes my 3d printer .. thanks..
I have done the same in the past :) 60c is usually enough
I've been watching people remove screens and such but I have yet to see anyone say how long they heat up the phone. I see in your video it's 158 F but for how long?
@Sorin. You mention Diana’s iPhone repair channel with one viewer. It seems to be an inside secret, since the viewer also knew about it. I tried RUclips, no luck. Can you please mention the full name of the channel? Thank you.

Please, could you make a video on how you connected battery charger with a testing and activation board for phone batteries that you have used in this video. Usually, those boards are powered by 4.8v-6v but you have obviously found a way to connect the voltage from the battery charger/tester to the activation board. Or I am wrong and it is made in factory and you just bought those two together?
Please check Diana"s video, she made a video testing the battery capacity
I have just become Diana's subscriber and watched the video you instructed me to see. In her video the activation board is smaller, probably limited to a few phone brends but in your video the board is bigger and designed for a large number of phone brends. I have asked Diana and you to possibly share the points on which you soldered + and - wires onto the activation board because your idea is very smart to combine the battery charger/tester and the activation board. Thanks in advance.
@@electronicsrepairschool hi there, what is Diana's channel name?
@@ivanr5315 Didi Tech Girl
@@zlane71 thanks
Just want to say that the HP charger cant charge and 9 volt. They do mostly at 5v and 19~20V depending on the model. Only if its new generation can do more voltages. The other cheap charger can do 5/9/12/15/19 depending on the model and if its good. So check the output voltages from the HP charger that you have.
Today we have pd, pps etc.
Otherwise great as ever
Nope, my hp power adapter has 5, 9, 10, 12, 15, 20
Yayy
Why would you replace the battery by an original part if you can just revive the battery with that tool of your friend?
I have problem with phone it doesnt turn on but i dont see shorts on motherboard. Its ALE-L21 Huawei.
Samsung is one of the worst repairs you will ever attempt. Sorin makes it look easy. This is the s8+ with the original frame. Customers think that a cracked screen is £40 repair. The rear always cracks and splits on removal. Go onto the more s20 etc and you will lose money. Great vid Sorin.
Samsung is one of the easyest to repair, back glass is removable quite easely if you know how to do it, nothing is serialized, almost all original parts are available to be purchased.
@@dexasdexas3784 You are wrong
@@56ty78ui I made a buck just by replacing batteries and screens on samsung mostly, Dexas is right, easiest money ever
@@56ty78ui samsung at 70degrees, isopropil and plastic from rx films everyone has. easy to open, use alcohol and you never crack rears again, be patient
Hi I'm here to learn how to calculate metal
you can put at 85º degrees no problem
Is there any degree/certificate required to start a repair business? Please tell me about your qualification? Are you university graduate or not? Plz tell
büyüksün sorin babaaa
sometimes, you rush through the satisfying parts, like gluing the screen.....lol
LOve the gloves your wearing now//
16:18: Why would they do that? On a similar phone which had a crack? Put the foil on there. They accidentally cracked it right away after taking it from the shop ? ........?? A little more clarification would be nice...........in my humble opinion.
Copies of original parts usually have been made with a little guesswork in mind, which can cause trouble with some functionality of the device ranging from something minor to something major which is why most people prefer to work with original ones unless the copies are very good and certified or they don't care a lot about the device working perfectly all the time for whatever reason. Customer is choosing most of the time, we make him aware of all the options depending on the device and current stock levels.
For screens we try to almost always buy one which has the LCD and the Digitizer together so we don't have to mess up with glues and risk of white/yellow/red or improper fitting and thus cracking sooner or later.

ce faci cind nu se potriveste in rama originala ecranu🤔
my main field 😋😋😋
The only problem with iPhones, for example, is that you can't find new original or genuine parts like screens or batteries. A second-hand, yes, but new ones, not at all. Because of Apple's policies. Also, there are copies and copies. Some of them are really rubbish, but others are so close to the original that you can't make any difference. Copy doesn't mean every time something bad or with bad quality.
Yeah, in the store i work, our number 1 repair is broken screens, people are so absurdly irresponsible.
If its "fast charging" why is it only 1.3A should be at least 2A for fast charging
If you can see, it consums more or less 13watts, which is 9v x 1.5amp, kinda aproximated. same as 5v x 2.8amp. both chargers do fast charge in different modes. if one is safer than the other is what i dont know.
@@CARLITOTESTIGO huh interesting if that is so I had no idea
Hello, with all m'y respect for you Sorin but this is not good idea to do à screen replacement like this ! Becouz you can order original Samsung screen " Original Service Pack"
Man im shocked if its original part then the screen comes with the frame.
Better yet, whomever books in the work: Have the customer turn on the phone, plug in the charger and make one call before accepting the job.
It's called "covering you ass"
Ni kavyu man ni wambu
he said samsung s9 plus but the screen said s8 plus
i always got samsung service packs to make sure the display was original, if they come with frame... well thats a easier less messy job for me :D
uimitor. bravo.
