I've inherited a HOX which I'm trying to set up for my wife to use. It has a very unusual issue, when plugged in either to a charger or a PC, it shows no indication of charging - i.e. no red LED. On a PC, it intermittently gets picked up as an unknown device - or more correctly 3 unknown devices, maybe mass storage, composite & MTP? Not sure cos it doesn't pick up any device info. As I say it is intermittent which suggests the micro-USB socket might be at fault.
But there is evidence that it is accepting a charge because every 10 minutes or so the phone vibrates and displays the initial start-up screen i.e. white background with HTC logo & it doesn't get past that. It doesn't show the 'Quietly brilliant' screen first like on a regular start-up. The screen stays lit for 3 minutes or so, then it flickers and turns off. Then it turns on again about 10 minutes later and goes through the same cycle. It does this continually when plugged in. I've also tried charging using the 2 end dock contacts and it goes through the same cycle. Also, the battery & board are both warm but not hot.
I've ordered a replacement USB socket which is easy to fit as its not soldered - this might help with PC access.
I've also tried using a variety of button combinations, but the buttons seem to be completely inactive and don't do anything either when it's in the 'on' or 'off' mode.
Any ideas? I've searched and haven't come across anyone else experiencing this issue.
Just realised that the charge port is soldered in place, not just pressure contacts. It's completely detached.
Has anyone replaced a charge port? Got soldering gear but that looks tricky...

It seems that wall charger of my Excalibur is not functioning properly. Following are symptoms:
1. When it is plugged in, sometimes it starts charging the phone i.e. amber light on phone is constantly lit and small plug sign appears on screen. But this happens rarely. Most of the time, the phone just doesn't respond i.e. nothing happens. I tried it on several wall plugs but it remains same.
2. When I connect it through mini USB cable with my desktop computer, it charges the phone always.
This indicates that something wrong with the charger though its just 6 months old.
Anyways, Has anyone else faced this situation? Can there be some disturbed setting on phone which are causing this? I have lately installed several homescreens songs etc on the phone. Please advice.
TIA,
KC
Hello
Long story short. Yesterday running PA + Lean kernel I sit down to play TURBO. After one and a half hour, I went back and put my phone down and plugged in the cable. It did nothing. I played a bit with moving the cable head plugged in the phone and started charging as AC. Unplugged, see if fast charged was toggled. It wasn't. Plugged back in. Nothing. Somehow, someway, I managed to connect. Was really hard to finish it and flashed back a stock yakjuwx (as my original rom was). Everything nice and good, but now sometimes I get the unrecognized device and have to unplug and plug back. Since than, these are happening:
- when devices is turned off, I plug the cable, the icon with bolt comes up, than switch to charge animation and it does disappear. Pushing the power buttons for a short time, not for long as power on, wakes the phone and displays the animation. Is this normal? or should the animation be displayed constantly.
- phones in battery stats doesn't show "discharging" it shows "not charging". Shouldn't it show "Discharging" when there is no cable plugged in?
- sometimes I got flashes as if is plugged in, the so called "phantom charge". (no, bending the tongue doesn't help).
NFC toggle off on doesn't help either.
Soon I'll send back the phone in warranty, as I bought it it was sent back one time for heavy temperature rised and video recording microphone problem, although they didn't changed anything with the microphone, just the motherboard.
Now I have problems with the sleep too... altough I had always. Here are some pictures attached.
I am affraid about not being able to unroot soon if the usb board goes to sleep... it's a matter of time I think... so any ideas?
My SM-T900 loses power and goes to a dead state, even though the battery shows 100% charged.
When this happens, I can:
Plug in the USB charger (both the charger and cable are Samsung OEM)
The screen shows a gray battery icon, with "0" in the middle
Within a few seconds, the battery icon changes to "100%" and fills with a green animation to the top
At this point (charger still plugged in), I can boot the tablet normally using the power button.
Once the tablet is booted, if I unplug the USB charging cable, the tablet instantly goes dead
If I leave the charging cable connected, the tablet still goes dead at some point (usually from 30 seconds - 5 minutes)
Any ideas from a Samsung expert? This sounds like it might be a hardware failure, but I know that software and hardware are very closely coupled on these devices. Suggestions greatly appreciated.

I found another thread here on XDA concerning battery-related issues with Samsung tablets. On a hunch, and the advice on that thread, I removed and reinstalled my battery.
The problem has been solved! It must have been a loose connector.

One day my phone fell off from my pocket (up to 20cm) while looking for something in the bag. Screen has cracked a bit, but when I came back to home and plugged device into a charger I've noticed that it doesn't charge rapidly, also there are issues with MTP mode, device doesn't detect that it's connected to PC it just charge, so I have to plug it multiple times until it detect that it's connected to a PC. Sometimes device displays on statusbar that it's connected, but switching to MTP mode doesn't work.
For first time I've thought that they changed "charging rapidly" to simple "charging" in beta 8.1, but it appears on both custom and stock ROMs. Device occasionally charge rapidly, so they didn't changed that.
It's like one week since accident. I'm planning to send device to LG for screen replacement, but more and more side effects slowly appearing, like 1px gray line on top screen. It's not a screen bleed, because it slowly disappears.
I was playing around with it, trying to set it up as a makeshift diy control center with an app and then suddenly the screen went black. It had been working perfectly for many years previously although the charging port was always finicky so I'd occasionally have to jiggle the cord to get it to charge (but I think that was due to the cords being too loose).
After extensive troubleshooting I concluded that it won't boot fully. The boot screen shows but in a flash it's gone, like a flicker. The device seems to refuse to allow me to turn it on when external power is connected to it, but if I sneak the charger cord in right as it is booting sometimes it will show me the battery charging animation for when the device is off (not sure what it's called but I've seen it on many devices as a standard feature) and it appears to actually be charging as it went from 84% to 87%. I also tried opening the device up and physically unplugging and then plugging the battery back in but that did the same thing as when holding the button without external power connected.
Is there any way to recover it or is it dead (it's been since 2011 that I have had this bad boy and I don't wanna lose him)?
