[Galaxy Note II Q&A, Help & Troubleshooting] geekoo:
Read on... before you just see the post and start flaming. :)

Been having a helluva trouble with my Galaxy Note II since a month now.

It all started a day in April when I was on a weekend break and my charger just stopped working. Not the charger, but the charger port. I even tried a few other chargers and none of them worked, whereas my charger worked on other phones.

So after the weekend without a phone I come back home and read some posts on XDA about moisture in the USB port. I blow dry the port with the hair dryer and things start working again. After a couple of days of flawless working, again the problem comes up. But it is nothing that a few 'frustrating' 20 minutes of fidgeting will not solve and so goes life.

There have been a few days where it has gotten so annoying that the phone simply wont charge no matter what I do and which angle I place the phone (yoga for phones, anyone?). The phone has even switched off completely at times. Yesterday was one of those days when it simply wouldn't charge.

So again I spend a lot of time on XDA and Google and what makes consensus is that there is moisture in the USB port, or there is something wrong (loose connection) with the USB port and it needs repair.

Few facts before we get to that, and my point about this being a software problem.

1. The charger, when it works, works flawlessly irrespective of whether it is on the table or hanging by the charger from the power outlet. I expect that in case there is a loose connection, the position becomes very delicate.

2. The charger, when it works after moving the wire around for a while, keeps disconnecting occasionally even though it has been placed on a stable table surface and no one is disturbing the table. After some seconds, it connects back automatically and begins charging.

2. The phone works without any problem whatsoever when I plug it into the Samsung car charger - never once do I remember it not working

Now here are my findings from yesterday after I almost broke the phone in frustration.

1. On a whim, I decided to do a factory reset of my device. After fidgeting with the phone for 4-5 hours and it not charging, it magically started charging after the factory reset.

2. After the reset and a 1 hour charge, I updated all the default software on the phone - including 1 samsung update, 1 allshare update, and 1 push service update. Within a few minutes of this update, the charger started showing the 'loose connection' problems again. I also noticed that at times the phone screen would switch on for no reason - for only 2-3 seconds.

3. Again I reset the phone, and force stopped some samsung services and disabled as many samsung services as I could and I could notice consistent charging.

I subsequently installed some apps (not going full out as I want to observe the behaviour) and occasionally the charging stops. I then go into the application manager and shut down some samsung services and more often than not the charging starts working.

After all this circus, I believe there is something wrong with the Samsung services, the phone device drivers, or the MTP service. It does something when it detects a cable being inserted and causes a malfunction of the phone. This is what it looks like to me.

In fact the same problem happens when I plug in the phone to the PC too. The connection keeps breaking and the phone is just not usable from the PC. However the interesting thing is that when the USB / MTP breaks, the charge is still working and the orange light is glowing.

So, finally the XDA relevant question. Can you guys help me find out if it really is a software problem or just some strange co-incidence? Are there any traces that I can pull out to see which app/service is causing the problem? There are many apps/services that I would like to disable, but they are greyed out - is there anything that I can do about them?

Mind you that my phone is not rooted - so all the usually available apps might not work for me. I use the phone as a corporate device and I can't violate rules by rooting the phone. :(

Any tips, suggestions, ideas, flames? :D
