The strangest issue I have seen with a Samsung Phone. Help appreciated! - Galaxy S6 Q&A, Help & Troubleshooting

Hey all,
This is a bit of a tough one.
I do quite a bit of phone repairs and I have my own little setup for everything and etc.
I got a Samsung S6 (SM-G920P) from my local market and it had an FRP lock - which is nothing for the most part.
Not thinking correctly, I just went to my Samsung Firmware, opened an XSA ROM for 6.0.1 and connected the phone via USB and went to flash. Fail. OK why did it fail?
AH - Because I am not using the right firmware for this (Thus I was getting the custom binary blocked message).
So I downloaded a 5.1.1 ROM and 6.0.1 ROM for the G920P and began to start the process again.
Put the phone in download mode and connected it to the PC, but I got "USB Device not recognized".
I thought it was a one off problem and reconnected it and it was all good. Loaded the 6.0.1 ROM and started flashing.
Completed successfully, no problems at all.
So then trying to do the FRP bypass with an OTG USB - I found it wasn't detecting it.
Thought, well, why not go down to 5.1.1 and make my way back up.
Connected the USB Cable and nothing. Tried again. Nothing. Tried another 5 or 6 times and eventually it appeared in Odin.
Started the flashing process and half way through it, the phone disconnected and now I have the "Connect to Smart Switch" screen on the phone and now any PC with all sorts of different cables will not detect the phone at all.
However - there is still power going to the phone as it's able to charge via USB Cable with no problem at all.
Next step - I took the phone apart so I could get a look inside to see if there may have been water damage etc.
Perfectly clean inside the phone. All flex connectors are fine, no corrosion and the WDI has not been affected.
Took a lot at the USB port and it's fine. All 5 pins are present and no damage is done. Soldering *looks* OK on the PCB, but it looks secure and the phone gets power no problems, so I am at a point where I am looking at this thing going what happened?
The OTG USB I tried in a Galaxy S7 and a Nexus 5X and both came up no problems.
All my cables I have are of decent quality (I assume so :/) and work with every other device tested.
I reseated the Flex Cable inside the phone for the charging port PCB and that hasn't improved anything.
Tried different computers etc.
Tried it with Smart Switch - doesn't detect and reinstalling Device Drivers didn't work.
I don't want to take the LCD off because it's working perfectly and I don't want to break it (You all know how fragile these screens are) - because I would replace the whole charging port assembly PCB - but this is why I am here asking to see if anyone else has experienced such a weird issue and can maybe provide some sort of an explanation into what exactly might be causing the issue.
And I was going to say would heating the phone up cause any issues with soldering, but I used about 30-45 seconds of heat to the back and the back glass came off fine. My thought that I may have damaged the port with heat is probably unlikely.
I don't know guys, the phone is still on and I have put it in Download Mode as well as left it in the Smart Switch screen and tried over and over and it's just getting power and not data (COM port in Odin).
I can post some pictures of the Micro USB port, the PCB etc if need be.
If someone has a solution, I swear I will buy you a beer!
Thanks heaps!

galaxy s 2 acting strangely, battery drain and randomly going into driving mode

I got my sgs2 about a month ago and its been like a dream, battery lasts for a long time phone runs ultra smoothly no glitches and nothing weird has been happening, but these last few days its just been really weird.
1) it started randomly going into driving mode, i dont even know how to activate it or what it does, but i think its draining my battery
2)When i was watching a tv show on my phone it thought that there was an hdmi cable connected and wouldnt let me hear anything through my headphones. i exited it several times but it still though there was a cable connected. Then i went straight home and quit it from the task manager and it worked with the headphines but that might have been a coincidence.
3)When i connect the charger it takes a while to realize that its charging and sometimes stops charging and says that the battery is too hot or too cold but when i feel the phone it feels completely normal.
4)When i connect the usb cable, other than taking a while to realize that its connected to a charger it doesnt realize that its a usb so i cant transfer files with my computer which i do often
5)I pressed home before and it took me to some sort of clock which i imagine is for a dock but i have no such thing
6) Even after using the phone for a while and using several apps the android os has used 59% of my battery, when usually its the display that uses about 30 or 40%
none of these things had happened before and now they randomly started all at once, i havent downloaded any shady apps so i doubt its malware
any ideas?
thanks
Are you using a stock firmware or custom?
Have you tried resetting back to factory default?

seems like majority of your problems are linked with the micro USB port, try resetting your phone and see if that helps. This is weird though.
It happened once to me on my sgs but that was because I inserted the charging pin without realising it was wet but it went back to normal a few days later and I changed my charger.
i was also starting to think it would be a micro usb problem,
would a factory reset fix it?
if so how would i back up my apps so that i have the same apps with the same progress on them, is it even possible?
or should i just wait and see if it goes back to normal?
I am also having this issue now. I've tried a factory reset with no effect. The phone is now largely unusable. Did you get a resolution? If so, how?
im having the same problem too .. wish it's just a software issue!!
the problem solved itself after a couple of days, i took out the battery and left the phone alone for about a day and after it worked fine again, not sure if it was the time or leaving it without battery but its working normally again
I'm having this exact problem - phone switches into driving mode, then says MTP is connected - then it switcheds to a strange lock-screen I have never sen before. It's really strange. I flashed a nandroid backup from a few months back and still the problem is there. I'd flash back to stock and send it in - but I can't connect to Odin via USB because of the problem. Is there anyway to convert a Stock rom to a CWM flashable file?
I'm desperate to get this sorted.
Experiencing the same. Has anyone a proven solution for this?
My phone, sorted itself out - should I say my wife sorted it out - by mistake. What I think she done was hold down the home button, and then pressed the power off button together and held them untill the phone switched off. When my phone came back on again - she had somehow removed the -Exclamation Triangle of the kernel counter and removed the problems from this post - that I'd been experiencing for abouyt 5 months prior.
Go figure - I now have a SGS2 that works beautifully again and has also had any kernel counter and Custom Rom flashing notifications removed altogether. I wish I knew why this worked, as I'm sure their are many who would like to remove the Triangle without a jig.
The other option that seeemd to work for other people was to clean the MicroUSB port of the device with a dry, clean toothbrush - though this did nothing for my problem. Good luck -I know how frustrating it is.
Help Please
Guys, I am Facing the EXACT same problem.
1.Driving mode on/off automatically
2.Showing a lockscreen which shouldn't have existed on this planet.
3.Hanging up unconditionally. Have to restart phone.
4.Sudden "mtp connections" and because of that "Media Scanner"
I own a Galaxy note just 1 month old! I was so angry that i wanted to sell this. But i couldn't adapt to any other smaller screens so, guess ill try fixing this.
1.It definitely is something related to usb port (Since i cannot charge my phone, i use an external charger)
2.Took my beloved to a samsung service centre, they said phone is waterlogged and showed me the motherboard, saying"IC MIGHT be damaged"
3.Cost for repair - $200
4.Cannot afford that. I am guessing they were bluffing cause i saw the shiniest motherboard ever
5.Please fix this, or ill be stuck with a Nokia 500 !!
6.I can, however afford changing the usb connector, anyone successful with that?
Edit: Did my homework and found out that its definitely a usb port problem. Solution:Clean the usb port. Ill try try it and get back to you ppl. Oh and about 20% of the world's population is facing the same problem.
Edit(2): SOLVED!!!
1. Turn Off phone
2. Remove battery.
3.Take a Brush with hard bristles(Toothbrush/Artist's Brush)
4.Take a pin.
5.Take your own sweet 15mins to perfectly clean the micro usb port using the brush. Nicely and Tidily, give all possible strokes to flawlessly remove any dirt in there.
4.Then take your pin(Be careful here) and gently insert it into the gap between that small metallic micro slab and the bottom part of the usb Connector and gently move it up, VERY GENTLY!!!
5.Clean the battery's charging plates using a cloth, i used my own T-Shirt.
6.Put battery in and REBOOT.
7.Clean the charging pin of the charger using the safety pin/Brush or both.
I have it on for 15mins and no problems. Removed and put the charger again and again, still no problem. After waiting for 1 week, i am able to charge it using its charger! Now lets see whether it lasts......:-/
Edit(3): So, my phone acted up again last night, with driving mode and car dock. I used the pin solution, No problem till now. its Peacefully charging. Bah! it really is annoying
Edit(4): Now, its been 24 hours since my last solution, and phone hasnt acted strange. I guess after another 12 hours ill rule out the permanent solution. Which i used.
same here
Well.. I'm having similar issue. Battery drain and random driving mode/voice search sometimes. It all started after last OTA update and rooting without changing a ROM to custom. I've clean out USB port and no result. Maybe it's time to scan system with AV or unroot device...

I had the same issues 2 weeks after i bought my galaxy s2. Took it to Samsung customer care and they replaced the micro usb port. Haven't had a single issue since.
PS: Try to dry out the port and the phone if it is a water logging issue. I used a hair drier to do that. Luckily the tab that indicates water damage hadn't changed colour.
Had same issue with my Samsung Galaxy Note - randomly going in and out of driving mode, used a dry, soft toothbrush to clean out the USB Charging port, so far so good.
Make sure to flick the bristles of the toothbrush back and forth with your thumb first as you might see a lot of dust fly off of it.
Don't use anything hard like a pin or needle as you might scratch the contacts.

It's just a software problem, the reasons might be:-
1) you might have opened and closed some huge apps randomly and very rudely..
2) You are low on space on the internal MMC Card
3) Your phone might be performing the restarting apps re scheduler
Solutions:-
1)Factory Data reset will not help as the cache section might be corrupt.. neither the android 3e will help...
2) a)Use odin and download the Latest firmware package from Sammobile's Website.
b) for tutorial on flashing, go http://forum.xda-developers.com/showthread.php?t=2488942.
c) Do not touch the phone after processes and restart was observed...
d) Again get into download mode and re flash the same Firmware again...
e) Restart the phone holding the HOME key, (it won't do anything by itself)
f) it will surely fix your Phone
3) Message me if any problem persists...

I registered on this forum just to say that this is a great solution. It looks like my phone is saved now
Hope it will not happen again.

[Q] [i9023] Water damage - USB won't connect to PC.

Hi there,
My Nexus S (i9023) phone recently fell into a water bucket and I immediately pulled it out.
Not much damage was done to it except of one thing: after I put it in a bag of rice like stated on the internet for overnight, and then plugged it in again to the charger, it seems like something was different.
When I plug the phone to the AC power - phone DOES charge, but nothing else happens.
It doesn't turn on screen and informs "charging", and doesn't have the "charge when phone is off" option anymore. Instead it would just turn the phone on.
Also, when connecting the phone to the computer nothing happens, it's just charging the phone! can't mount USB anymore
I took the phone to a lab which handles these cases. They replaced the USB port and cleaned all the corrosion. They said it's fixed now, and indeed the USB port is new.
But then after coming back home it's still the same.
I'm sick of being dependant on other people and would like to fix it myself.
Any clue which part of my phone was fried? Where can I get it?
Thanks!

Are u rooted?
Try a different ROM. Maybe one ur ur backups.
If it still does connect then it has to be the ROM assuming ur computer has the proper drivers still.
Good luck
Vs Nexus S 4G
Thanks!
Thank you!!!
Problem solved after I loaded one of my backups.
Any explanation to that? even when the phone was turned off it couldn't charge it in off mode and now it can.
How come it's a software issue?
Thanks!
I can only guess that ur ROMs kernel had a "fast charge" option. If so this doesn't allow computer connection. How it got switched to that option... who knows .... maybe the sudden power surge.
If not that, then ... strange things happen when a phone get wet.. the sudden power surge could have changed the power output causing CPU adjustments... who knows.
I'm just happy it worked for u.
I'd recalibrate ur battery asap.
Good luck
Vs Nexus S 4G
Hi, the same thing happened to me, only it wasn't a bucket, it was a pool, and changing the ROM didn't work (I've flashed at least three different ROMs since then, kind of hard when the USB port doesn't work but eh, what can you do).
Also, it's on a Gio, not a Nexus S, but the principle should still be the same, yes?

[Q] Desire S, USB not working but charges? Pls help.

Hi
I recently bought a Desire S from a friend. I went about rooting it but when I plugged it into my PC it is not recognised at all, literally nothing pops up on the phone or the PC.
I've checked the settings in the phone and USB debugging is enabled and I always changed default connection type.
I have even booted into Hboot and plugged the USB in, but still nothing.
The phone charges perfectly fine and I've tried plenty of different cables. My other Android phone works perfectly when plugged it.
I'm starting to think its a hardware issue, anyone else heard of this? common problem? any fixes?
Thanks
Re install htc sync and drivers, then remove sync and try again
“Pressure is something you feel when you don't know what the hell you're doing.”*―*Peyton Manning
I have the same problem, sort of. When I plug mine in all is well at first, but give the phone one tiny nudge (or just wait a few minutes) and it goes back to charge-only mode. It's probably a slightly loose connection somewhere in the USB port on your phone.
To be sure, try if it works in Linux. The Linux USB stack sucks infinitely less than what Windows uses.
Thanks for the replies. I tried Ubuntu but exactly the same (it worked with my Nexus 4)
Thats a little annoying, thankfully charging still works, just unsure how long that will last for! plus I cant root it! but I dont exactly need it rooted but I tend to do it anyway.
I've sorted it now. It was a loose ribbon cable, plugged that back in after taking the phone apart and its working.
Bootloader unlocked and custom recovery flashed. Ready to rock.

[Q] Help... rogers infuse can't connect to pc all drivers removed and reinstalled.

This all Started about two months ago when my cousin could not use her phone because it was cracked to the point that it was painful to tap or swipe. she gave me the phone to fix the screen but then i started looking up stock android roms and figured that since all that skinned old samsung sh** was going to cause more of a problem than it was going to fix, so i decided to attempt an update. Shortly after i plugged it in i noticed it wasn't showing up but i thought kies might have a solution to the problem but it didnt. I have used usbDeview to remove all drivers and reinstall using kies as well as an isopropyl bath to attempt removing any caked up shiz on the inside of the usb port but none of that worked. i have taken a good look at the usb port from all angles including with the housing removed and nothing seems to be out of place but it still cannot connect. it is on rogers so i cannot oneclick root it and since i cannot connect it to a pc i cannot root it the old fashioned way. Does anyone have any ideas on how i can fix this completely broken phone

Does windows pick up anything? Including something unrecognizable to it? If so, the adbsetup-1.3 drivers should work fine.
If nothing shows, check your cable (try another), make sure you are using a USB 2.0 port, and sadly, that's all I can think of, that stands between you and a broken device. Hope this helps.

Nexus 5 won't connect to anything over usb

So recently I started having this problem. My Nexus 5 stopped charging all of a sudden.
After messing around I found out that I could charge the phone when it is turned off, but when I boot it (while connected) it doesn't show the charging icon. Only when looking up the battery status at the setting menu it says charging.
To my surprise fastboot was still working (adb wasnt) what brought me to think it's not the hardware.
So far I have done a factory reset, wiped everything, installed stock kernel and recovery, downgraded to stock 5.0 (I don't even know why, just thought its worth a shot...).
At some point I took the phone apart to try to determine whether I tore out the connector itself, and noticed nothing.
I'm really running out of ideas here... I can live with having to reboot the phone for charging, but I really need it to connect to the computer.
Any help will be appreciated!
You tried different USB cables and chargers? USB debugging enabled? Computer is a trusted machine in adb?
I have 2 computers on which adb is trusted. Both stopped working. I tried a few cables, all of them worked with another phone, but did not with mine.
Adb is enabled. :/
Did you try revoking all computers and re-establishing trust after flashing a stock ROM?
Strange that fastboot commands work and adb doesn't.
Nope, but I tried connecting to another one and no dialog popped up.
Btw, an hour ago it just started working... All of a sudden...
I should be happy, but now I have no chance in finding what was the problem.
Anyways thank you for now, if I have any more issues I'll update.
I assume it's physical damage to the usb board/module (since it started working while no change to the software was done in the past few days).
I will order a new one just in case.
Thank you again guys!
Maybe a loose internal connection? You could try removing the back to looking for loose connections.
Did so, didn't notice anything strange.
I do have experience with soldering, but I would rather not touch it before I get a new one, just in case I screw up. Small components are no fun.
The thing that still bugs me though is I had fastboot working perfectly fine all that time. Oh well
