[Q] Samsung Warranty on International Phones

Hi Everyone,
I am from the USA and bought a S3 Mini 6 months ago on Amazon since I needed an unlocked phone for traveling abroad. The phone was working fine but now just will not turn on or charge. There it wasn't dropped or exposed to water. Amazon won't let me return it since it's been over 3 months, the seller also won't let me return it, and Samsung USA is saying they cannot help because it is an international phone and inside the battery case it says it was made in Vietnam. I called Samsung in Vietnam and they said I have to contact Samsung USA.
Does anyone have suggestions on what I should do? I tried contacting Samsung on Twitter and they haven't responded.
Your help is much appreciated!

I can't help you with the warranty, but if you can find another battery you may want to test using that first.
If the battery really really flat, you can try connecting the phone to charger for half a day. Happened to mine once, it did not even display charging.

Thanks for the advice. I tried getting a new battery and charging it without the battery for day. Unfortunately, still nothing.

New unboxed redmi 4x speaker faulty

Hi all,
Just received a brand new redmi 4x from HongKong and the main speaker isn't working.
I've tested it using the inbuilt tester (settings,about phone, multile tap on Kernel, single test, speaker) not a whisper from it so I'm 99% sure it's faulty hardware.
I'm not sure if I can be bothered to wait for sending it back to HongKong for a replacement and they don't have an international warranted (as far as I know?)
Probably I will order a new speaker unit and change it myself.
Anyone have any inputs on this?
Look a fairly easy disassembly according to Youtube videos. Anyone have any experience to share?
why no warrenty?
Warrenty there is, but i ordered the phone from Hong kong and the lead time for returning, and recieving a replacement is gonna be nearly two months.

A word of caution before you buy refurbished Z3+ / Z4

Just sharing my experiences here. If anyone here who's interested on used z3+ / z4 . By used I meant refurbished. I suggest to put to rest those thoughts, forever. I bought one that seems to come from Japan from wholesale online. Sometimes it's Docomo or AU branded(you'll get what what I'm trying to say later). Mine came with 1 week warranty. I return mine's within 1 day as I had a problem with the rear camera. I got the replacement unit. Then I return it again as I found out that the display came off from the bottom within 2 day. I return the phone again. Then I got a unit with a faulty flickering lcd. Then I got a unit which seems usable at first then only after my replacement period had finished I found out that it got faulty battery which in my case it turn off and show low battery warning even when it still had 70% charge left. I replaced the battery which cost me $12 myself. Then the problem still shows up. I thought that maybe it's the problem with the firmware. But, the problem don't go away even after I hard reset and through sony companion. I return it only to found out that the motherboard itself is faulty. As the replacement motherboard is expensive. It has become a living brick somewhere on my shelf . I knew I should't have bothered with Xperia but I can't help it.

Buying parts fro repairing Nokia 8 Bluetooth and WiFi antennas.

Hello ladies and gentlemen.
[Quick story]
I bought this phone from a seller on eBay (offir.123), which sold me as new. I've sent to my friend's house which is in the USA and left a positive feedback because my friend looked at it as a new phone and didn't pay any attention to the details.
He sent the phone and when I got it, I've just found the problems:
Screen problems (LCD with glue marks)
WiFi disconnecting and being rejected by any router
Poor Bluetooth connection.
Well, even though I've sent messages to the seller, he just gave me a middle finger. My mistake in this case for leaving a positive feedback before getting the phone in my hand.
Remeber this seller: offir.123. Don't buy from him ever!
[Issue]
So I had to buy another screen from China and it just arrived today.
I've just replaced my screen and noticed that the WiFi cable was damaged. I believe this was the cause regarding the issues with my WiFi connection. I've even another topic opened here regarding the WiFi disconnection problem.
Now that I've closed the phone and all, the Bluetooth is not finding any device. I believe that it might be related to a damaged antenna too.
[Question]
Can you guys point a place where I can buy these WiFi and Bluetooth antennas and send to my home here in Brazil?
I looked over eBay, but haven't found anything yet.
I've attached some screenshots from Nokia 8 Teardown video made by JerryRigEverything.
Found it
Okay, like my other posts, I'll reply to myself.
I found a seller selling parts from Germany. He sends worldwide.

I hope this helps anybody in need.

OG PHONE 2 BLACKOUT OR DEAD?

Its been a month now since my rog phone 2 is dead or sowhatever you call it.
No display no power no charging indicator
But when i connect it on my pc using side port it keeps detecting it.
Is there anyone knows how to fix it?
I really use all my allowance just to get a gaming phone like that and i don't wanna waste it
Hi. I faced the same problem. I found out in two repair centers that due to constant overheating in games rom (ufs 3.0) in my rog phone 2 broke. This can only be solved by buying a new board. I, for example, a couple of days ago profitably ordered this on AliExpress sale for $ 150. Now I'm waiting for the package. It seems that this is a fairly widespread problem with this smartphone.
My asus rog phone 2 broke down half a year ago, when this problem was still unknown to anyone. I have not visited the forums for a long time, but now I found that this problem has become global. It's a pity that such a good smartphone turned out to be of poor quality. Only now I have the funds to pay for a new motherboard. If interested, I bought here: https://a.aliexpress.com/_9vTVx1
