Just a quick question - what do you use to remove the glued-in battery? Samsung doesn't use the pull-tabbed adhesive and it's basically impossible to remove them without risk of damage. I had some success with isopropanol, but you seem to use a more dedicated solution.

[@MovilonePhoneRepair]

TheUn4seen , I’m using contact cleanner pcc 15, you can find it on Amazon! Best regards

[@bobmiah]

can i ask what may be the risk of damage please because i want to make sure my a40's battery can easily be replaced thank you

[@TheRealFobican]

I really wonder why they didn´t do a real dettachable lid instead of one that is attached on the phone with glue.

[@Kopfkirmes55]

The customer might get wrong ideas, like replacing battery instead of buying a whole new phone.

[@rickvdwiel93]

yeah, there is no profit from that. I don't know what they going to charge me within like 3 years from now. If its more logic to buy a new phone, I will just do that. I notice that 64GB loaded with apps will also consume all the 4GB RAM, which is not going to be enough. So upgrade would be necessary anyways I guess.

[@Mike-oz4cv]

Small plastic clips can be less reliable than glue. It would be great if they’d just put the screws on the outside and sandwich everything between them. Instead of gluing on a mostly useless back cover.

[@DonMikson]

Could you please tell if you used some glue or something when reassembling the cover, is the old glue ok or are there snaps?

[@MovilonePhoneRepair]

You can use b7000 or t7000, industrial glue. Thank you for watching our tutorial! Best regards

[@fieldmarshaljoe]

If you pause at 2:47, on above the brass threaded hole for the screw (to the right of it if the phone is upright) there is a small silver chip. What is this? I dropped my phone down my lift shaft and I’m Replacing the screen and housing as it snapped, all internals are fine EXCEPT that silver chip. It fell off. This video was helpful to locate where the chip went, I’m not sure if it was soldered on or adhesive as I couldn’t see any residue of past solder on it. It seems to be tacky enough so that after I put a peg/clip over it, it isn’t falling off of the board anymore. I may put some glue over the top to keep it in place. Do you know what the chip is for? Thanks

[@fieldmarshaljoe]

Perhaps a sensor? It looks like it’s located next to the front facing camera.

[@EfficientMan]

This looks like a crystal oscillator but is an odd place to be so maybe not.

[@Leahdepeahhh]

Can u dry it from the inside when it's wet? Or will that damage the phone even more? I get a ghost screen because it's wel from the inside

[@MovilonePhoneRepair]

Doggobrosvevo, the ultrasonic cleanning is the process that you have to perfom it when the device is dissasembly.

[@aceryeo8409]

While removing the back i cut what appears to be a small aerial next to the motherboard coaxial aerial connection. Can I buy a replacement part. It is labelled E1 10 M2 A4-E4 and T15 190605,

[@MovilonePhoneRepair]

Did you look for it on Aliexpress?

[@NegativeCZ]

during disassembly i broke that golden cable on bottom (MAIN1 R16 190901) but everything seem to work, any idea what function this connection have?

[@southsidetrojans5232]

What I'd the black bit of film for on the inside as mine broke and wont charge

[@JCD275]

When I turn on my mobile hotspot, what will offer the best signal? Lying down screen up , or standing the phone vertically? Just wondering

[@cherrygirlw]

Technically, having the antenna perpendicular to the receiver is the best way (at least it's how it works on RC planes, no clue if that applies to phones).

[@SuperBODY90]

I replaced the battery and now I have no 4G network connection after assembly. WLAN is working, but no 4g connection, so it is not possible to call somebody. The phone always shows the error "Not registered in Network". Do you know why? Before disassembling everything was ok. I also double checked all connections.

[@lopwidth7343]

Nice repair

Where can i buy screen desplay for my samsung galaxy a40?

[@miharozonicnik2653]

4:39 what conector is this?

[@elmervandermooren3268]

According to another video, this would be the screen connector

[@themarkpearson]

Thanks for that tutorial, it was really clear. I've just had to replace the charging port on two phones. They both failed at about the same time - slow to charge and no data transfer. A bit of a poor design I think.

[@MovilonePhoneRepair]

Hello, Mark! I m glad to hear that! Thank you too for your comment! Best regards

[@seemiihalainen7603]

My a40 charging port also broke and it wont charge at all and it got fixed and also my friends a40 had problems with charge port it is literally garbage port

is it possible to replace its wifi card?

[@MovilonePhoneRepair]

You mean ic wifi + bluetooth?

[@heyRicardo...C140]

@@MovilonePhoneRepair right

[@heyRicardo...C140]

is it a discrete removable component, or you didn't mention it in disassembling the phone just because it's integrated onto the mainboard?

[@paraskevasmavragannis2923]

the heat you apply .... how many celcius ?

[@bm952]

I used a phone heater app

[@bm952]

It worked xd

[@dzole00]

Can you change the charging connector if your screen is broken without having to change it

[@MovilonePhoneRepair]

'XeNoN ' yes, I can because, for changing the charger connector you need to open the devise by the back cover so it a not any risk with the screen! Let me know if you need more information

[@dzole00]

@@MovilonePhoneRepair Thanks, i'm asking you because i went to my local dealership and they told me that i must change the screen or it will divide the phone in half

[@anshathebe2237]
