Hi all,
Have a Samsung Galaxy Note 8 running stock Android 4.4.2 I have used an OEM Samsung charger and cable always. But recently had to replace the charging port with an OEM charging port because it completely stopped recognizing the cable.
The install went well and the port works fine.
But I recently plugged in an OEM Samsung MHL HDMI adapter to watch movies on the tablet on my TV. Adapter works great!
The problem arises when I disconnect the HDMI adapter an then plug in the regular charging cable. The cable is not recognized. And it does not charge the tablet.
The tablet will ONLY charge if I use the HDMI adapter plugged in to the OEM Samsung wall charger. I have several OEM Samsung wall chargers and OEM charging cables, but the tablet will now ONLY charge with one specific cable attached to one specific charger and connected through the OEM Samsung HDMI adapter.
I used the adapter once on my Note 3 phone, and it has no troubles connecting to any other charger. But I amit, I am hesitant to attempt to try it again with the phone. I have lost the portability of my tablet now, since it will not accept my portable battery charger either.
Any ideas? Is there some sort of setting I have to change before disconnecting the HDMI adapter? I thought it was hot swappable, although I do not try removing it while it is sending. I turn off the tablet then remove it. Am I looking at doing another charging port install? Is this common with the Note 8?
Thanks for any help.

I had that happen as well not too long ago. Took the blasted thing apart and found that the MHL adapter's usb plugin to be cheap. Had broken internally. So I bought a cheap o replacement. Fortunately the replacment had a good quality usb port, so that said, should not have the same issue.
Think I have discovered part of my issue. The MHL HDMI adapter connector is considerably longer than the standard micro USB connector. This new Port is quite snug. Didn't think much of it after initial installation, just figured that old port was worn out. I think the snug fit may have allowed some shift of the port internally, even though it is screwed in. This small shift is just enough to prevent the micro USB from making proper contact.
I was able to utilize my portable battery pack when in the field with the tablet. Just connected the pack via the hdmi dongle. It worked.
Thank you for your insight.

Bought official Samsung galaxy S3 MHL Adapter from Best Buy... Finally a brick and mortar store had them. Some initial impressions below. Will update if I find anything new. Rooted s3 on stock ROM and interface.
S3 charger with BB cable and on 1080p Panasonic Plasma TV: Worked fine but only showed in 75% of screen (surrounded by black bars above and below). Did not test for lag.
iLuv 3 port charger with BB cable on 760p Panasonic Plasma TV: Worked in fullscreen on TV. S3 slowly lost power watching crackle, Tmobile 3G+, wifi off, plugged in 1amp port, no other devices plugged into charger. Tried same with S3 stock charger and BB cable and phone charges under same conditions.
Update: I bought a Kensington Absolute Power 2 port USB charger to charge an Asus Vivotab Smart and the S3. The charger comes with an adapter for charging tablets at up to 2.1 amps. With adapter, the S3 read around 2000mA which I am afraid would damage the phone,so I plugged it in without the adapter (per instructions). Without the included adapter the phone read around 700mA.
Again, I tried the the Samsung S3 OEM MHL adapter with the Kensington 2.1a USB charger (no adapter) and the phone slowly lost power. I tried this with both the S3 stock USB wire and a Belkin charger+data wire. I tried again with the stock S3 charger (1amp) through the MHL adapter and it charged the phone while viewing. Same Crackle episode, same 3g+ internet,same TV.
I am afraid of trying this setup with the tablet adapter for the charger, as I am afraid it will damage the phone. As a side note, I am using a 3500mAh battery from seidio.
Update: Tried the 2amp charger listed above with adapter. Interesting conclusion... besides having a strong enough power supply, you still need the OEM Samsung charging cable to charge and use MHL adapter at the same time.
In other words, the S3 charging cable with the Samsung S3 MHL adapter will charge the phone. Other cables resulted in a slow loss of power.
Update: Bought a Samsung universal charger listing 0.7 amps. Using the Samsung universal charger cable with 1. the 0.7 amp Samsung wall adapter, the 1.0 Samsung original S3 wall adapter, and Kensington 2.0 amp wall adapter all resulted in charging the S3 while using the MLH adapter with my TV.
In other words, the phone still charged using the Samsung branded 0.7 amp charger cable.
I’m having a problem charging my AT&T Galaxy S3 rooted. No USB cables work to charge my phone. Whether it be the one it came with in the box or one from wall mart. I’ve also tried all the USB cables, HTC, Samsung, and others. Also tried the USB mini Best Buy sells for these phones.
Before I had this problem USB cables would work just fine but all the sudden they stopped working.
The only way I can get any USB cables to work is if I hold it at an angle and itll charge and stop randomly but charges very slow if held at an angle.
Only way I can get my phone to charge is if I use a wall charger. I have tried all the USB cables with my car, lap tops, and usb to wall adapters.
HELP PLEASE!

That's a hardware problem.. not much we can do about it. You most likely damaged your USB port and will need to replace it.
You can contact mobiletechvideos.com for their services if you don't know how to replace it yourself.
I just got the Samsung Multimedia Dock EDD-S20EWEGSTD
I don't know if it is supposed to work this way but if it is, then it's garbage. The problem I'm having is that the USB ports only work when the phone is fully charged. I tried the OEM charger cable/adapter as well with the same result. I thought the USB ports were defective but later tried it after the phone had fully charged and everything worked as it was supposed to. I thought it was because I had used a different HDMI cable and plugged it into a different monitor but the next time I tried it the USB ports weren't working again. The only thing that changed is that the phone isn't fully charged now.
DO the USB ports work if the HDMI isn't connected? I tried to see if it would work as a multi charger but there was no output from the USB ports at all when the HDMI wasn't plugged in.
So for a while now i've been using the official S3 wall adapter that came with the device and a third party USB cable (The original broke about a year ago), but now that second cable has also stopped working. I bought a new cable today, again third party but it refuses to work in the official Samsung charger I put it in a Nexus 10 and also a raspberry Pi adaptor and it worked for both of them, but with my Samsung adaptor it refuses to work! It briefly charges the device and then stops completely... odd?
I should also note, when I connect it to the phone/computer it charges and syncs as normal, so it seems to be not playing nice with the official wall charger, is this a common problem?
so i have two usb cables and original. 2.0 amp samsung wall charger, the samsung cable i use for wall charger at home so when i setup my s3 as a AP i need constant 2.0 amp from charger keep up with the demand and charge the battery at same time but now i cant do that i have turn off hotpot and leave the phone alone so i can charge. i brought in my car usb cable, and now i can hotpot and charge at the same time no problem, so what is the problem with other cable? i mean cable still works and i still can use it for data transfer etc...
just cant use as heavy demand cable.
I have some cables from the "box o' cables" we seem to collect that have the same issue. Some of them won't keep up with the s3 others won't keep up with my n7. I notice it more with older cables so it seems to me that its the cable breaking down or wear on the contacts inside the connector itself.
