Battery replacement - Samsung Galaxy S7 Edge Questions and Answers

Dear all,
Could someone please tell me how a battery of S7 edge is replaced? If i give it at an official outlet, and get it replaced, can someone from other place while selling the phone, come to know that the phone was opened?

They have to weaken the glue on the back of the phone (the machine they use to do this also weakens the glue on the screen.). Then they lift off the back glass and replace the battery.
If you get this done at a Samsung Certified Repair outlet then you would never be able to tell that it had been done and the phone will remain water resistant. If you have this done elsewhere, there's a high chance they will not do a great job, leaving gaps and the chance water could get inside the phone.

[Q] Battery connector broke. Can I fix it?

Hello all
I had a leak in a roof, when I returned home my Streak was sat in a puddle of water. It's affected only the four small battery terminals, but unfortunately due to subsequent shock damage, one connector has snapped out of place and is no longer springy.
As I can't see any visible screws I have no way to assess this myself, but does anyone know if I would be able to order the small battery connector part and fix this myself?
The water damage hasn't affected anything else so I know it's just the one battery terminal that's broken.
Thanks in advance for any help anyone can provide.
You might be covered under your house insurance, if not the cheapest option would probably be to buy a broken one off eBay for parts.
Thanks for the response.
There's no insurance on the phone - Dell customer support requires a tag number and of course this isn't a desktop PC.
Does anyone know where I can simply buy the part I require, just the battery terminal box?

Nexus 4 Back Glass Replacement Help.

I know this is a silly question. But I cracked the back of my nexus 4 from a 1 foot drop, (out of my pocket while I was crouched down spray painting in the garage). Just before I did this I was starting to have battery issues, basically under 20% the phone doesn't charge unless its off. Even on the stock charger, it just loses power and then dies and turns off again. Its frustrating now because I lost my warranty due to cracking it.
So My question is, if I go on (Ebay) and buy that glass, will I be able to do a clean enough install that they will take it as warranty and not notice? I don't want to buy the whole back assembly because its rather expensive with all the antennas to keep everything working.
I'd like to hear your opinions, or from people who have replaced just the glass before. Thanks.

You can do it, you just have to take off the entire back cover, peel off the NFC and charging coils, and gently pry out the glass. Look up the thread where someone put in a second battery (total of 4200 mah) in his Nexus. He has removed the (shattered) back glass off of his phone, and replaced it with a plastic housing for the 2nd battery. You could see how he got the glass off without damaging the cover. The hardest part I would think would be getting the glass to stick on while keeping the stock look. I don't know what kind of adhesive LG uses to glue on the glass, but ideally you would want to use the same kind.

Sweet man thanks for the input I'll go take a look at the thread.

Water damage :( what now?

Hi. This happened a while ago but I finally have the time to deal with my poor Nexus 6p. It spent a few minutes in a hot tub a few months back. Rice for more than 48 hours - nothing. Brought it to Staples where they put it in the machine that heats the gel balls (?) to remove the moisture. Charged it for a few minutes there and it actually turned on! Awesome, except the touch screen doesn't work. Battery seems to hold a charge, screen turns on and looks fine, volume and power buttons work, and I couldn't figure a way to test the fingerprint scanner or camera. Factory reset it. So now the phone is stuck to booting to the options menu with recovery mode and all that.
Is it possible to determine or guess what is wrong from this information? I've looked at the teardown, and I'd assume there is an issue with the pressure sensor, but I don't know enough about phone construction and parts to know if it's the sensor, or the part that connects the sensor to the screen, or something completely different.
I wanted to get some advice on what to do from here. Other than tossing it or leaving it forever, I have three options:
1. Repair shop: This seems like the easiest option, but potentially expensive enough that I'd be better off getting a whole new phone instead. Would a diagnosis be a separate process/transaction than the actual repair service? There are a few nearby shops for me to check out.
2. Fix it myself: The 6P seems like a pain in the ass to take apart and put back together (2/10 repairability score). I don't think it's beyond my ability, but the time and risk that it involves for me to do it myself makes me very hesitant. I also don't know exactly what I'll find inside the phone.
3. Sell it: Sell for parts and buy a new phone. If it comes to this, I need to know what I should expect to get for it. It's good hardware, and the parts that still work seem in good shape.
I wanted to consult the internet before going any further. So, how boned is my phone? Any different suggestions? Thanks for reading and I appreciate any advice.

You could flash the factory image but I guess you still wouldn't get past the setup screen without touch. I've been repairing electronics for 10+ years and if it came into my work I would disassemble it and look for obvious signs of damage/corrosion at the screen/digitizer connections, and look for track marks on the motherboard where a short could have occurred, or blown fuses/resisitors/diodes for the digitizer. Beyond that it's really a matter of swapping in a screen assembly (we have cracked glass 6p lcd assemblies that would work fine as a test unit). If that doesn't fix it, I'd order a main board. Having said that, it's not a phone I would want to own or even repair for a customer without telling them about the potential for future issues from the water damage. PM me if you want to sell it cheap for parts.
Screen and digitizer assembly is 'only' $60 - $80 on ebay or ali. So that is worth the risk. If this is not the problem you can sell it again for the same price, so no money loss here.
Waiting a few months though, is a long time to wait to dry your electronic devices. When it happens the best is to take it apart immediately to avoid corrosion.
The 6P is not easy to take apart, but it is do-able. Hardest part is the glass on the back. But if it cracks, a replacement will cost you less then 10 bucks.
What I would do is order the screen, take the phone fully apart, if there is a lot of corrosion, wash the mainboard in a contact cleaner (or if you don't have this, wd40 could work) then wash it with alcohol (to remove the wd40) and let it dry. Assemble the phone with the new screen, and hopefully it works. This way I fixed an Oneplus One 6 months ago, and it is still running perfectly.
To add a bit of clarification - use 99% USP Isopropyl Alcohol. It shouldn't be more than five bucks at your local pharmacy (Shoppers Drug Mart in Canada sells it for $1.99 for 500mL).
While using the 75% USP won't cause any serious issues, it is diluted with water, as it's more of an antiseptic (I can explain why 75% is better for wound cleansing than 99% if anyone wishes), and you'd just be prolonging the drying/repair process.
Use a lint-free cloth to dab the components - keep it away from the battery terminals on the battery itself. It is OK to clean the connecting terminals on the motherboard though. There are sandwich clips all over the LCD/motherboard, so be extra careful dabbing the cloth in there - one bent pin in any of those clips and your phone will need to be sent away for repair by a specialist.
DO NOT POUR IT ALL OVER THE COMPONENTS OR LEAVE IT SOAKING IN ANY AMOUNT OF ALCOHOL.

Should internal liquid damage be covered by phone warranty

The LG G6 phone I purchased in may 2017 fell face first and damaged the front glass, so I sent the phone for repair and got it back somewhere in October. Three weeks later the phone suddenly switched off when it had 15% charge left and refused to charge again. So I sent the phone back for repair and just got the repair quotation.
According to the company that will be repairing the phone, the repair won't be covered by the phone warranty, as it has internal liquid damage and that I will have to pay $400.
Now I don't agree with this for a few reasons,
1. The phone never fell into the water, let alone do I remember having any water on it.
2. Even if the phone had any water on it, how could an IP68 certified phone let water go inside the internals? If it wasn't properly sealed, how could the consumer be penalized for it?
3. After the first time repair, I had used the phone close to three weeks, how could there be corrosion in that time?
Now I spoke to both the company that will be repairing and LG, the customer service agents are both useless, as they have no answers for me. So I am going to try writing some emails.
Has anybody else had this issue? And does anybody feel I am being unrealistic here?

Water resistant NOT water proof.
Barely any manufacturers cover liquid damage.
Been fixing phones for 15 years now and don't think I no any company that covers water damage.
Corrosion will happen quickly. With a drop of liquid and a current flowing through it.
Phones that are liquid resistant just have a thick sticky seal that the screen and back glass stick to really well stopping liquid getting in.
Plus all ports and holes have rubber seals inside.
Just take it apart and clean all parts with alcohol spirit cleaner. Let it dry and test phone.

Will it retain the waterproof feature after replacing battery?

I'm planning to replace the battery because it lasts way less than before but if the phone gets opened will it retain the water resistance features or I will have to forget about it?
I want to have a new battery but that is one feature I don't want to lose.
I've replaced by battery and it's up to you to use the right gasket glue and apply it properly, or get someone who knows what they are doing. I've not tested mine since, but the seal is as good as the factory applied one.
There are YouTube videos on how to do it, the hardest part was separating the glass back without breaking it. Also, finding a genuine battery is very hard, as 99% of those on sale are fake.
