I try to post here to ask if there is a sort of debugging/logging way to find the origin of my problem.
When connected to the USB cable, the charging icon starts blinking as if the cable is connected and disconnected continuously. In this condition the phone is not charging, but will discharge very quickly. It’s also difficult to connect to your computer to update or sync because it’s difficult to establish a stable usb connection. This problem does not occur when the charging is done via the magnetic connector. This is the second Sony Xperia Z2 with this problem. The first has been replaced by Sony as a defect under warranty, but without success, the same problem occurred after a few days of use. I observed that the issue is started again after after using the magnetic charger . I've also tried to reset the phone and make a full recovery but the issue remain.
I would like to understand if it's an Hardaware related problem or is a software bug.

hi all,
my x10i suddenly stoped charging. It was connected to my pc and I noticed that the LED light is not shinning. Then I tried to charge it from wall adapter and car charger, but with no result.
Sometimes when Im lucky, it connects somehow and charges a while, but my pc wont recognize it.
My question:
Is it a hardware defect?
yeh I want to know the same thing. My phone suddenly stopped charging at all. I tried several different chargers and USB cables, issue remains. Computer wont detect as when USB cable is attached no light on x10a? Can someone help and question remains the same:
Is it hardware related defect?
also how can it be fixed?
It is most likely a hardware problem. The fix requires some soldering work to be done.

USB socket at fault.
Today i found out my SGS2 have problems charging the phone, not only that. i also have problems with USB file mode, and keis mode. and if the phone is turned off. i only once got it to charge without booting. else when i connect the USB it boot the OS.
What weird thing is, that ODIN works without problem every time!
The problem appeared after upgraded to Darky Rom KG6 with jkay mod. but don´t think it has anything to do with that.
I reflashed to a Stock KG6 (still same problem)
From OS restore to default, and format (still same problem)
tried to flash back to KE2 stock. an but on CWM, and clear battery stat, and system cache.
flashed backup with a KE2 Kernel (still had the same problem)
What i found out is that, when i disconnected the wall plug charger, the phone still was in a state of charging. and it don´t give the sound notify when attaching the USB. but when touch the USB cable it suddenly charge and give the sound. but it can also go in MTP mode. or start Voice recognize.
Could the be a faulty USB port on the phone, or can Battery State and kernel updates have something to do with this problem?
im now pretty sure this has something to do with the USB port. when i just spoke on the phone. it suddenly began to change between Car mode a normal.
i than tried an alternative why to deal with the problem. I tried with a hairdryer after taken out the battery, sim and sd card, and carefully heat the back of the phone.
for 5 hour there has not been any problem. both the desk dock, and wall charger is working.
got a dejavu from the xbox days and RROD.
I have the same issue. I think the USB port is faulty.
The phone reacts to different electrical resistor values on some pins of usb port that triggers car mode, desk mode, etc. So, somthing is faulty in the usb board that reports to the system that has something connected to it: charger, car dock, desk dock, usb jig, etc.
I can't find any solution on the forum, I tried with several roms and got nothing.
So... I'm waiting for a USB Jig to reset counter, back to stock rom and send it back to store for warranty
My problem seems to be fixed by using the hairdryer on the usb port. I think the problem appear from the why you hold the phone and if your hånd become sweaty. Because there are nothing to protection the usb port like the sgs1.

I hope this could work for you too
Hello, I received a Verizon galaxy s4 for screen repair. After replacing the screen I tested the device and it worked fine. The issue that I encountered was the USB port, I would connect it to the phone and it would not charge it nor would it show up on the PC. I though it could be a faulty USB Port on the device, so I ordered a replacement and replaced it. Yet I still have this issue, even while using a brand new USB port/ribbon/connector. Does not matter if i connected it to a wall charger, car charger, battery charger, or to the computer, it will not read the connection and will not charge or show up in the computer.
I need help in fixing this issue, I really don't know what to try and cant even think of possible things that are causing this. Don't know if this is a hardware issue or software issue.
Hello all,
Honor 7,
PLK-UL00
B341 and EMUI 4.0
Android 6.0
Im unable to use my phone as USB Mass storage device. When i connect my phone to PC sometimes im getting as USB device not recognized and sometimes im not. I tried different PCs and different cables. ITs ONLY CHARGING
tried cleaning the micro usb port, uninstalling and reinstalling drivers in Pcs but it didnt work.
I switched off my phone, removed mem card, reinserted it, swithced it on again, connected my phone to PC(in sleep mode)
phone is detected as storage device and got notification in notification panel to select as charge only/files mode/ photos mode.
After ejecting and removing cable again back to issue. No detection. OTG also not detected. No Data transfers are being made but its only charging( even through Car USB port)
Anybody facing USB not recognised problem ? i hope its software related.
could anyone let me know of solution.
Thanks.
I am also facing the same issue
I thought I was alone in this issue.
Basically, my problem is, the wall charging and USB connect are reversed. i.e., I connect my wall charger, its showing as USB mode and when I connect the cable to a PC, its showing as AC Charging. I tested with Ampere app and when I connect to AC Charger, it is drawing only around 300mA(like it would do if connected to USB) and its drawing around 1.5A(like it would do when connected to wall charger) when connected to USB PC.
I have been having this issue for quite sometime and recently, I had upgraded to Marshmallow through OTA upgrade. I thought atleast this upgrade would fix this issue but I am still facing the same issue. I even contacted the customer care and nothing useful advice other than restoring to factory settings was suggested(which I tried and didn't work).
I guess it should be some software issue but don't know what it is or how to fix it. Any inputs would be welcome.
Hello, first of all apologize for my English.
My Xperia Z2 has problems with the USB connector, I know you have some reports of this, but I think I have not found any solution yet. He is almost 3 years old, I think it is normal to present problems, but I still do not want to change my cell phone.
I am having serious problems trying to connect it with the charger via usb, I have to wrap the cable around the device, pull to see if I find a way to connect it, when it connects and starts charging, after a while it starts to hurt Contact again.
When I bought the phone, I used a magnetic charger, but because it was not original cables, it went wrong and I decided to use it for the same cable. I saw that some problems occur because of connecting the magnetic to the opposite, but it has almost 2 years that I do not use and the cell phone always charged normally.
Any solution?
Hey,
I started to have the same issue until it stopped altogether. I had to disassemble my phone last week to fit a replacement LCD and digitizer, and noted that my USB connector had actually snapped off from the logic board!
~TL/DR~ The simple solution is to make use of the magnetic charger. You can get the official charging dock or cables. Both are cheap enough, easy to use and charge the device rapidly.
