Is this Samsung J7 alive? - Samsung Galaxy J7 (2017) Questions & Answers

So recently I bought a Samsung J7 for literally pennies. I don't know history of this phone, but screen its cracked and not responding and its always black (don't want to turn on) as it was described on ebay. Charger doesn't work, it does not vibrate, generally dead. I disattached lcd and gave up, but then I tried to connect it to pc. My PC showed a notification that Samsung J730F is actually plugged.
And here are my questions:
Is this phone dead?
(if not) Will new display work on this phone?
(if yes) How do I know what is the problem in this phone? Can I somehow measure voltage to see if it's actually charging?
Thanks in advance and sorry for bad london

i have the exact same problem!!! It just started yesterday.
Do you use the original charger?
If you use a other charger with less power, the phone will not charge!
You need a 2Ah Charger.

Yes i understand, but i use the one that came with the telephone. Its the original samsung USB Cable 3.0 + the Charger.
I tried with the Charger from a Galaxy Note 2 ( usb 2.0) it still doesnt work.
It's a hardware problem.

As said is hardware issue. If your Note 3 is under warranty use it, because they will fix it. If not, go to a phone repair center and they should be able to fix it as well.
It might be the microusb from the phone, a friend of mine had something similar with his s2.Good luck!

Back up your data with your backup app of choice (Helium, Titanium Backup). Throw your backup file into dropbox.
Your photos should be backed up in drop box so don't bother.
Contacts are in your Google account don't bother with that either.
So I think it's just Music and movies if you're not using Play Music.
I would use sd card for back up, that's one of the reasons it's there. I backed up contacts on my old phone to Google and then for some reason couldn't recover it on new phone, maybe I did something wrong, but had no problem loading them them up from sd card. If you really hate to send it back (I would) you could open the back (search youtube, there are few videos how to), I think it's 8 screws and check if the charging board connector is loose. I wouldn't go much past that and would make sure there are no temper proof seals to disturb.
Hello how you solved this problem? I discover exact the same problem with charging on my n9005 today.
Pretty sure this is related to the software on this, not the hardware, unless they are all broken. I have recently sent mine in for the same reason, got new note 3 had it for a week now. But before sending it in i got a new battery, new cables, nfc charger and a cradle, to rule out all the chargers as a possibility. After getting the new one it worked fine until I updated after all updates came down now it wont charge again. I found that If I remove the battery and put it back in it will start charging from time to time but currently its off and charging sort of, Keeps starting to charge for about 5 min and then stops for about 10, and keeps this cycle. If anyone else has a new one and still getting this after Updates please let me know.

Problem fixed!
I had the same EXACT problem for a couple weeks. It clearly isn't a hardware issue if the battery actually is charging when off (FYI to anyone who needs a refresher on how technology works). Clearing the system cache took 30 seconds and worked! Here is how to do it:
Turn off the Galaxy Note 3.
Press and hold Volume UP + Home + Power buttons.
When the Android System Recovery screen appears, release the Volume Up and Home keys.
In the recovery menu, navigate to ‘’wipe cache partition’’ with the volume buttons.
Press power button to confirm.
Once this is done, select reboot system now.
Requesting your help!!!! pls... Super urgent

So after a lot of reading online and understanding logically that if the hardware is screwed then the phone will not charge in the first place, I followed your steps and wiped my cache. I was literally keeping my fingers crossed that this will be the end of my long haul with this problem. However, the phone did not start charging after that and the problem still persists. I strongly believe that this is a software related problem as the phone functions fine and the battery life is also as it was before. Given this, I kindly request you to tell me if there are any other solutions or ways through which I can fix this issue? Your response is most appreciated and urgent.. HELP!!

Ok, wiping the system cache worked for about 2 hours. I was a little too excited. I just replaced the charging port and so far, so good. Make sure to buy the proper charging port; each one is different per carrier (e.g., mine is a SM-N900V for Verizon, SM-N900T for T-Mobile, etc.). The charge port was $11. You can find all carriers, except Verizon, on Amazon. I googled Note 3 replacement parts and picked the most legit looking website to order mine. Good luck.
did any one found out any solution for this

Help! My Galaxy Note 3 N9005 Won't Turn On

Hi Everyone! I have a galaxy note 3 SM N9005 32GB. I've started facing a very weird problem recently that I cannot find described anywhere in quite the way I'm experiencing it.. My note 3 powered off by itself after running out of charge last night. Ever since then, the only thing that happens when I plug it in to charge is that the screen stays black and the phone only vibrates once. No charging LED indicator, nothing on the screen at all, just a black screen like when the phone is off. In order to get it to vibrate again, I have to do a power drain before connecting it back to a charger. There's nothing on the screen at all. Can't boot into recovery or download modes and it's not detected by a computer. Have tried multiple cables (USB 3.0 and 2) and have 2 batteries which were working fine till this happened.
Any idea of what's going on? And if I can back up any data from it like contacts and messages? Thankfully, I had transferred almost every app I could to the micro SD card (128GB Sandisk) and was able to at least recover my notes from colornote, but I digress. What is going on in my phone?
Additional info - the battery is probably still charging when I plug it in. I think this because the phone and the battery warm up after being plugged in for a little while just like they used to when the phone was working.
Even more additional info - I don't know if this is relevant, but I recently upgraded to the most recent OS version available. I think It's a 5.0 or something but I can't remember exactly. Also, the front camera stopped working some time after the upgrade. And 2 days before this, 2 apps refused to update for some reason. I don't know if this could be related.
TL;DR - Note 3 N9005 ran out of charge and is now almost dead with black screen and no LED but vibrates only once after plugging in or pushing the power button. To get it to vibrate again, a power drain needs to be done. The battery is still charging because it gets warm when plugged in.
I too had the same problem but when I connected the phone it would not even vibrate like completely dead.
Maybe try these:-
1)Connect it to the pc of it detects it then recovery would be easy.
2)Connect the charger properly.
3)remove battery for like 30 minutes and try the steps 1 and 2 again.
4) If still not working go to the dealer cause I had to go to him too. ?

I bought it off of amazon, any suggestions in such a case? Besides trying to send it back, I mean. Anything or tool I can try? I don't mind if it gets technical. Need to get my app data off the internal memory.
Though mine started with a different problem than yours, since today it seems like the problem is same like yours. Phone's display is totally black, yet I can go to download mode (cause phone is detected by Odin), I flashed the latest stock ROM of UK too, but now there is no change anyway. I want to be practical and think that this is a display problem, if not I will be more than happy. I have to send the phone to a local technician I know, lets see.
The only think I believe you can do is wait, for maybe 6-7 hours or so, with the battery detached, and then insert it back and see whether its booting with display on or not, if not its more likely a hardware issue, display possibly.

A5 Blue screen of death and now actually death

hello im doughlas ..
the story :
i remove the SD card directly without going through the settings, then immediately turns blue and can not be turned off and getting hot from the back cover , and I wait for the phone turns itself off and I tried to charge its battery back.... im not getting anything , no blink LED charging , no detect on USB mode , or anything..
im tryin ask to several technician in my town , some say the Internal , LCD , and batteries.
but im not sure with all guesses so im open up my LCD by my self and tryin to change my LCD with the new one , but still i have nothing ..
is anyone having the same problem with mine ??
do you recognize what is the real problem is ??:crying::crying::crying:
regards
Doughlas
Samsung recommend holding down the LOWER volume and power keys simultaneously for 7 seconds and it worked for me on my A5. No more BSOD (Blue Screen Of Death.)
Make sure the phone is charged.
How does A series have LED charging indicator?

is my P10 plus dead?

Hello everyone,
i recently acquired a used P10 plus almost for nothing.
the guy i bought it from said it fell on a carpet and it wont turn on anymore.
the symptoms were:
*black screen
*red led blinking (first 3 fast blinks, later only 1 every couple of seconds)
So i thought to myself, probably battery issues from the fall, maybe it disconnected somehow.
I disassembled the phone, reconnected every cable, but still same symptoms.
i read somewhere that red led usually means battery dead or the small charging motherboard (?) is broken. So i ordered both from Aliexpress and installed them today, but still the same issue.
i connected the phone on the charger without the battery, the screen came on (but it seems its broken also - only vertical lines and a crack, lol).
Any ideas?
should i order a new screen and try to fix it or should i give up? (i read somewhere that people couldn't power up their phone after screen replacement)
thank you guys in advance!
well, i guess ill just give up.
i was hoping for an idea of what to do, but nothing.
a shame really, i was hoping to get it back to work again.
cheers!

Galaxy S8 G950F Motherboard issues

Hello XDA Members !
I own a Galaxy S8 G950F model and I bought it with SIM Card Reader known to malfunction...the issue is that I odered a new SIM READER and I failed replacing it. What I mean by failing is that I haven't managed to remove it from the motherboard, even after I heated up that zone at 200 degrees Celsius. After I realised I need to contact special repair services I reassembled the phone and the volume up button was stuck as it was pressed but it was some motherboard issue, not the button itself. So I dissasembled the phone 3 or 4 times and I still couldn't fix the issue, few minutes after that phone went dead and came up to Samsung logo after 5-6 tries of reflowing the hole motherboard then went dead and stayed dead...
Now I know the motherboard might be dead but fun fact is that if I connect the phone to my laptop via USB, if I keep Power Button pressed phone connects to PC as "Exynos 8895" but no drivers can be installed and phone storage is not showing up...also I want to mention screen has no input and no LED is turning on when charging or connecting to PC....
Not so worring about the phone, any ideeas are welcomed, I own a P30 Pro now and a motherboard for S8 in my country is around 80-100 bucks but it makes me put some questions and maybe I'll find a workaround...
Any ideeas?
