[Q] Changing something something inside can affect phone? - Hardware Hacking General

Apparently, my Samsung Galaxy Y Duos is malfunctioning(Fast battery drain and overheating) so I gave it back to the store and gave them my warranty. And they said they had to change something inside.
But then, my aunt warned me that opening the phone might affect the touchscreen and make it sh!tty.
Is this true or is it just some hoax? Since I'm really worried about it.

Liquid damaged phone

My father bought a new Galaxy S for my daughter a few weeks ago and gave it to me to store until her birthday a few days ago. The phone was in my wardrobe, in the box, sealed and not used in any way.
On her birthday, it was unwrapped and charged and played with but we noticed almost immediately that the signal strength was very poor and varying wildly continually. We thought nothing of it but when we checked with another Galaxy S, we found that the signal was nearly 2 bars lower all the time and there were many times when the signal just vanished altogether.
I contacted Samsung and they asked me to send the phone in to their service centre but when they got the phone, they reported back that the phone had been water damaged and was therefore not covered by the manufacturers guarantee. I told them that the phone was brand new and unused but basically they, told me to go away - I guess that no one admits to any damage!
They also sent me a photo of the damage and, on inspection, it's a picture of a single solder track which looks like it has some corrosion on it. There was no damage visible anywhere else on the phone at all and no other damage on any other surrounding electronics is visible.
I have not asked them if the liquid damage indicators had changed at all but I did look at the other Galaxy S and couldn't even find the indicator anywhere!
Can anyone suggest what I should do next - the cost of the repair is very high and we simply can't afford to get it done at the moment.
If you know someone with required knowledge, try to clean the rust.
It´s a standard reply from Samsung and possibly a standard picture.
As moisture damage is almost impossible to disprove, that´s what they like to use.
Try to compare the picture with your actual phone and eventually talk to your lawyer.
whats your location i might be able to do something about it.

[Q] what would cause the screen to look like this?

My friend bought a note 4 and after 16 days it began to get purpilish-black splotches that looks like spilled ink on the screen. He brought it to ATT and they tried to tell hi that the screen was cracked (it's not). This picture is what it looks like today (about 20 days after purchase and 4 days after it began to happen). Any clue what would cause this? Any help would be appreciated because ATT is not trying to help at all.
I guess I should mention that his blutooth was having issues since he got it, and sometimes when he'd call people they wouldnt be able to hear him.
I feel as if this is a faulty device, but ATT isn't having it. They keep trying to say he did something to it. The phone is only 3 weeks old, never mishandled, never wet. What could this be?

would that be a factory defect?
Hard to say, I doubt they will accept it under warranty
Regards
Happened before on my note 3 after i dropped it. It will only get worst until the entire screen will become black.
It can happen even if the screen is not cracked. Odds are it's the result of the device being mishandled even unintentionally.
Looks like a simple fake.
I wouldn't accept it under warranty, that thing is a mess! No way it happened "on its own". Maybe he was frustrated with the bluetooth and call issues and he threw it against a wall?

Your friend should ask the ATT guys if its was really due to mishandle such as drop or thrown away, they should be some dent or scratch on the phone body. If ATT guys can not find the defect of body dent or scratch, then ur friend have a point there and should can claim under warranty..

Weird question: how can i shorten the life of the device?

So I have a note 3 n9005 that is two years old. When I bought it I purchased 2 years of extra waranty (so I had 4 years in total) which also gave me premium service. Means that whenever my phone gets defective and I go for a warranty repair, if they do not fix my phone in 5 business days I get all my money back (the initial price I paid back in 2014). I updated to a s7 edge and gave the note to my girlfriend, but I didn't take good care of the phone: the chrome bezel is all washed out, the screen has a few micro scratches etc. So I'm thinking of intentionally shortening the life of the phone somehow. Apart from the battery, the phone still works like new and it still performs very decently compared to today's standards (kudos to samsung for this durable phone lol).
So is there anything I can do to "brake" my phone, but it would still be covered by warranty?
I'm thinking of running a very intensive app non stop while keeping it charging. Maybe excesive heat will do the job in a week or so...
If it's an accidental warranty, you can always drop the phone and tell them that you accidentally dropped it . OR you can try Hard Bricking the phone after rooting and flashing some wrong bootloader through odin so that the phone doesnt even boot up. After that, just tell the warranty guys that phone suddenly stopped working.

It's not accidental warranty, it's like a normal warranty just extended for two more years. Won't a brick of any kind leave any signs that it was rooted, or the software was changed? If they find out its my fault they'll likely reject the waranty.

I accidentally emmc bricked my Note 1 [N7000] before warranty expired, and the phone didnt show any boot screen in any way (Completely dead). And the guys at Samsung changed motherboard (i think). But I was lucky in my case.
I have a better solution to your bezel paint peel off problem. Just buy this case, its really awesome and it covers the bezel and replaces the lame old battery cover with pure aluminium .
Kommandant Case
Or you can use any other case for that matter. In the case of micro scratches on the screen. Suck it up bro, its just micro. : )
Does anyone know how to hardbrick this device without leaving a trace that it was rooted?
Since this thread is basically about committing fraud, I'm afraid it will have to go.

Samsung Galaxy S7 DUOS (G935FD) Hardware Advice

Apologize if this is the wrong forum as most threads I've seen on here are usually software related, but wanted some technical input.
Goal Get a working phone again for the cheapest price, bonus points if I learn something along the way, am okay with accepting the risk of ruining my 'broken phone' even more.
Samsung S7 Edge DUOS broke (no response to charging, no LEDs or lights at all) while traveling in Europe. Took it to a Samsung Paris service center and they said they were pretty sure it was a motherboard problem and I would need to send it back to Asia to fix it, especially since it was DUOS.
I'm probably going to order up a new motherboard myself and attempt a DIY repair, partially to save money, but also for enthusiast purposes. No experience with my phone, but tinkered with computer hardware before (delidding Intel CPU for overclocking purposes and did minor case modding).
1) I see different motherboard models such as for Verizon, AT&T, etc. But the physical specs of all of them seem very similar (minus the DUOS), does that mean I can buy a non-DUOS board for my phone bezel/case/camera? I got it originally from my brother and have no interest in dual-sim capabilities at all. If it means I can get another similar performing board with domestic US shipping (most used DUOS boards on Ebay/AliExpress ship internationally), I would rather prefer that.
2) Anything I can do to make sure it isn't a motherboard problem? Given the backstory and only 2-3 minutes of testing in the back (not sure how long it would take a technician to hook it up to a multimeter), the service center rep said he was pretty confident it's a motherboard issue.
3) Anything I should look out for? Make sure the motherboard doesn't have a blacklisted IMEI? I'm actually a bit unfamiliar with phone hardware, are the drives, RAM, etc. all complete with the motherboard? Or are those externally hooked up elsewhere in the phone? The prices of the motherboard complete set seem to be pretty cheap to me ($60-$100 range).
Backstory
Received it from my brother who bought it in the Philippines. The most physical damage it's ever taken was slipping out of my pocket while sitting and hitting a hardwood floor, phone worked fine for months. While driving one hot day, my phone just died while using the GPS, last I checked it was about 70% battery, and then the screen turned black and got very hot. After some googling, I waited for the phone's battery to die before charging it back up, and sometimes made it to my home screen/photo gallery, and other times got stuck in a boot loop. It would still have a blue LED indicator on the front, while being hot, and could boot the phone up in recovery mode. Although it kept giving me partition not found errors.
Did a factory reset and for some reason it miraculously worked. Re-downloaded apps as I needed them and phone seemed to work just like new again. Then 2 weeks later on the plane way to Europe, was using an GBA emulator for an hour or so, before closing the phone to sleep. Woke up to the phone very hot to the touch, non-responsive, no LED's, figured I would try waiting for the battery to die down before plugging it in again - no luck.
1.
I swapped a Duos Mainboard in a Non-Duos Display, there was no Problem at all, i think you are fine with buying a normal board, only internally the Card Slot has more Pins, but the Card Caddy is the same.
2. It surely is the board, if the phone gets really hot, it's not the battery. And a broken Display would also not make a phone get very hot out of nowhere. And yes, the whole computing stuff is soldered on the Motherboard, CPU, RAM, Modem, Controllers, IC, almost everything. So if it's not a short in the USB-Port, it is the Motherboard in my opinion.
3. I dont know anything About blacklisted IMEIs in Europe. Maybe you should look, that the board is not Google/Samsung locked.
Btw, you dont Need to wait until the battery runs down, it's also not very good for your Display and battery if the phone is so hot over a Long period of time. Simply hold Power+Home+Volume Down to do a hard reset, which should Always work.
Sorry for my bad englisch!

Swollen battery, how to change it?

Hi everyone, I've had this phone since the day it was released and it has never failed on me, and I've always charged it correctly not usin it while charging and not overchargin it and never letting it die from battery low
Anyways, recently I have noticed that the back of the phone is slightly bulging up, it's still veeery slightly and to be sure im not mistaken, i put ut on a flat surface and saw that the phone is standing on the center of its back. Where XPERIA is printed.
Is there a way i could change the battery myself at home? Or is it even easy to be done by a repair shop or not? There arent any Sony support centers in my country.
Btw, I havent noticed any changes to the routin batterylife of my device

Assuming you can get access to the battery, when you get the battery out you will notice the plastic skin around the battery is bulging. Use a pin an pop it, then the gas stuck insde will escape. Then put back in your phone and your done.
I did this for my Xperia Z. No issues... good as new now.
i will try to do it, hopefully not exploding my phone or hand
the reason why im hesitating is that Ive heard that the NFC will most likely get damaged when trying to change battery
