Hi,
I have this strange problem happening since yesterday on my brand new Salsa. When I put it on charging and leave it on a wooden table, the touch screen responds weird to my touch. The ring lock will not open all the way or shortcuts will work weird. The soft keys at the bottom too go absurd not responding or giving different options.
If I pick the handset (probably providing grounding), everything works normal thereafter. I'm using only the original charger provided with handset.
Additionally even the sound into my car's auxillary port is behaving as weird filtering or dimming the vocal frequencies but allowing the music to get through.
Does anyone know why this is happening?
Only incident to have caused this I guess is when the sales guy I went to plugged the phone onto a blackberry charger yesterday for a few seconds.
Could it have caused some damage to some internal part - diode or something that is leaking AC voltage onto the capacitive screen ? Can I have it repaired at HTC ?
Since it's not even a week old, I'm too distressed about the weirdness. PLEASE HELP!
does seem like it could of done some damage as blackberry's do take a lot more juice than the salsa, personally i would take it back and tell them about the problems you have had only since the dude abused the phone lol
I will surely be taking it back but want to confirm if its the problem with the phone or charger, because I do not see this problem when I charge from my laptops USB.
And I want to know what it is before I take it to them. Its much safer to find the problem and tell them rather than allowing them to figure it out themselves and in turn damage something else.
Thanks
your laptop will deal 5v 1a max before the computer will cut off the usb supply due to risk of overload, new blackberry chargers deal a lot more than that due to the juice the device needs to charge, almost like different laptop chargers the difference in the supply would kill your laptop, i don't have any problems with my device regardless of surface it is resting on.
I have the same problem
I have the same problem, but it was observed from the time of purchase. So do not worry and take the phone in hand))
Resolved
With some searching I resolved this problem or I can say I at least know why this is happening.
It is the charger that is faulty and not the handset. I changed it with another HTC charger I had and the problem disappeared. I figured the most logical explanation is what I read in one of the post elsewhere in this forum.
The charger could be faulty to be leaking some AC voltage along with the charging DC juice. This leaked voltage interferes with the sensitive capacitive touch screen. If we hold the handset in hand, we are providing a natural grounding and hence the problem disappears.
I personally would not like this to continue and so I'm going to take it back to my vendor for replacing the charger or if the need be, buy a new one.

Try using another charger and see the difference. Hope you can get your charger repaired or replaced!
Take care.
this is due to a grounding problem or/and leaked ac current....
This problem occurs when your charger supplies more power than required by the phone to charge.The only solution for your prolem is changing your charger.

I had once another problem, that my Salsa overheated (red-green blinking) when I charged it and my Wifi was on. Maybe a background-process could be responsible.
Rooted but stock OS2.2, I897UCKB1.
I think this started only after I had to do a factory reset (sigh), but now, the Cappy will not stay on, or turn on, while being charged. Plugging phone in to power causes it to shut down immediately. This is NOT a random shut-down problem.
I'm trying to figure out if this is software - i.e., some setting somewhere in the phone or an app that got toggled - or hardware, a problem with the charging port.
Ideas, anyone, about how to solve it? Is there an app I might have that would control or correct this? Phone's beyond warranty but insured, so I have that option if it's a hardware problem.

What happens if you pull the battery, plug in the charger, and try to power it on?
Sent from my SAMSUNG-SGH-I897 using XDA App
Pulled battery, plugged in to outlet, tried to power up - no response at all.
Any thoughts as to what's going on and how to solve?
Try flashing back to a stock firmware of ur choice and see if the problem will still be present. Just a trouble shooting thought.

Was hoping to avoid that -- I have stock Froyo now.
One more datapoint - the battery DOES charge while phone is plugged in, I just cannot turn it on (and if it's on when I plug it in, it immediately turns itself off, without shutdown screen). I have also tried different charging cables and plugs, to make sure it wasn't a short in the charging apparatus.
I was hoping there was an app setting that might be forcing the close. Otherwise, odds seem high it's a fault in the electrical "wiring" to the plug, no?

Maybe try a different battery just to rule it out. You could try going to an ATT store and just asking to use one of their batteries on a show room Captivate to see if it fixes the problem. It might be a hassle to do, but it would eliminate something from your list.
Solved - but no answer
The good news: Phone's staying on while charging now. The bad news: I'm not sure why.
I had swapped out several different cables and batteries, plugging into computer and into electrical outlet, but the phone would not stay on . Had not had time to call AT&T, which was next step (out of warranty but insured).
HOWEVER, I used the car charger during a road trip, expecting the phone to turn off...and it did not! Great! So when I got home, I tried a cable with the wall charger and it stayed on, and it now stays on with all the combinations that did not work before.
My totally uninformed guess: Something in the car charger plug must have cleaned or straightened out the receptacle on the phone, which was misaligned but not badly enough to cause a short, since the battery took the charge.
I hate solutions like this...IAC thanks for the ideas.
Hey all,
Before I even start here, please no snide replies about using the search box on here or anywhere... if the answer is out there, I'm at a loss for the keywords to get it. Fair enough? As FYI, bootloader is (was??) unlocked, rooted, and has cwm recovery.
So I dropped my MB886 cracking the screen (round of applause please) and in the process of disassembling the case to install replacement I tore (severed) the battery connection cable. Fast forward to phone now reassembled with new screen and battery installed --> -->
The phone now has a green LED that will respond with blinks to button certain presses i.e. the simulated battery pull, but the device doesn't show up in lsusb output or device manager. I've read of similar problems where the phone has been brought back, and I've read of the exact problem with no solution. Basically the only two things I've really read that supposedly work are battery pull button sequence and using OEM charger/cable to get battery to take a charge.
Unlike, say the Atrix 2 where the lonely white LED is there to serve as a reminder that it is a hard brick and that's all you're ever going to get from it again, I haven't even read that this is in fact the #1 sign device is now a brick. So could someone verify it is or isn't? I've never tried to access a device this way, but Is JTAG an option?
I don't get why this should be, despite battery issue, it's all simple hardware swapping involved here as the software wasn't touched and was 100% working even with cracked screen.
Thanks for anyone with an answer or the direction to one.
2 things it could be then: you over- or under-tightened the new battery cable screws to where there isn't a good connection with the board. The screws have to provide equal pressure on the positive or negative contacts or otherwise there's a fault in the circuit.
OR
Your new LCD/digitizer is defective OR wasn't seated well.
Since it was working before, and since you didn't break anything else (to your knowledge), those are the two things I would check.

hey, thanks for the input. I remember battery connections being snugged when I originally took it apart, and to be honest, short of having a mini torque wrench I don't know I could put them back any closer to that. the digitizer could certainly be either defective or perhaps have a bad connection, and i am certainly willing to test/check for either, however do you know that this would prevent the phone from booting or cause it to only display the green led as a sign of life? something of the "halt on all errors" in pc bios? seems logical that the led would (or could've) been used like the oc speaker and blink out some code relaying you've got a bad O2 sensor or the gas cap isn't tight.
Over tightening can cause problems. So loosen them a bit if it's just-short-of torque wrench tight. I don't know why it does, but I've read people had problems when they over tightened those screws. That green light could be telling you that the battery is connected poorly.
Is there a possibility that the battery is so depleted that it won't charge? For that, you need a factory cable to charge the battery with power off.
Sorry, to clarify, no I just snugged the battery connections when reassembling, I only meant that i don't think i could get them any closer to the way they were originally without aid of something like a torque wrench.
As for battery charge as a potential issue... to be fair, I only have a OEM Moto wall charger and I think the cable I am using is Samsung. Surely the cable itself isn't the weak link in this chain? A car battery on a multimeter reading 12.0 volts is something like 50% charged and about 12.8 volts is looking pretty good, anyone know what I should get out of the 3.8V Li-Ion on a meter?
PS I double checked the both data cable connections to the motherboard, so I doubt just a bad connection is to blame here.

You should get from 3.8 to 4.1.

When I say "factory" cable, I'm not talking about the cable that came with the phone. There is a special Motorola cable (that you can even make yourself) that can charge your phone in situations when your phone is normally not willing to accept a charge.
If all else fails, try this: http://forum.xda-developers.com/showthread.php?t=1077414
Yes! This is brilliant and certainly answers a few questions. It'll take me a bit to get this together to try it, but I'll post back when I get a result. Cheers!

Scratch my previous answer. Seems I misunderstood what a "factory cable" is for. It can't actually charge your battery, instead it is used to power the phone so that you can flash/diagnose it, even when your battery is dead. Normally, you need a working phone to charge the battery (with the stock "charging cable").
This information may or may not help you. At the very least, using a "factory cable" may allow you to power your phone on, which would tell you whether the problem is your battery or the phone.

well, i'll take it regardless... i've acquired one of these mythical factory cables and it gets me into fastboot and recovery, so i'd wager, even though i haven't seen it, that it would boot all the way. so being that i don't have either the original charger (although have one that's motorola) or cable (samsung), my best bet is probably just find a store that has both an OEM motorola charger and cable even if they're not for the MB886? surely one for a moto x would work to charge battery, no?
or is this like a chicken and egg problem i now have? a catch 22? i can't charge the battery without a working phone, and i can't have a working phone without a charged battery? golly gee, anybody out there with an MB886 want to charge my battery for me? can i just hotwire the battery to a couple of leads from a charger and bypass using the phone as the charging device? at least to give the battery say 15%-20% to get something to happen... like get this rain cloud perpetually parked above me to blow over from above my head for a day or two maybe?
so, with phone plugged in with "factory cable" here's what i get and when... the phone bootloops on the "bootloader unlocked" warning screen if i don't press anything. volume down gets me fastboot, volume up gets me recovery. phone shows up in both and takes commands... so is it possible i just need to restore a nandroid backup, or is the battery charge the better bet now? i would just try the nandroid for $h!ts and giggles, but the last one i have isn't as fresh as i'd like, but is certainly usable if i must.

Any generic USB charging cable SHOULD be good enough to charge and flash your phone, especially a Motorola cable. I'm currently using an old Blackberry cable for everything. They should be all the same. In rare instances, a cheap cable may give you issues (I think I had a cable from an old Samsung phone that I couldn't get to work right).
I guess just keep trying until you find one that works. Hate to tell you to go spend $20+ on an official Motorola charger...
Regarding your battery, yes you may be in a bit of a pickle. I've never had to do it, but I've read of users who had to short some leads in order to directly charge the battery. Trying searching through the forums, I'm sure the info is here.

All hope is lost, I am now looking for a replacement.
Ok, so here's where I am at with this now... As we're basically talking about any regulated power supply that can put out an excess of (around) 3.8V and 800mA I've opted to use an old ATX computer power supply and wired the mini B USB end of a cable known to have in fact to have charged this very phone... nothing. I have also, for sake of hope, even tried using the wall wort from an iPad (which puts out a cool 5.1V and up to 2.1A). The green LED will shut off after a while of being plugged into said charger, but still no booty action.
As stated before, the phone still works with the factory cable.
So, I gather from this that...
A. some hardware component (i.e. resistor, etc...) on my phones board that is involved in the charging process has gone kaput.
or
B. There is some software flag flipped somewhere that could be unflipped with or without some trickery to what actually is VS what I want the phone to think it's seeing.
Anyone have any thoughts on this or something similar pertaining to B as a course of action?
*update to my update* ... umm, which should now be up to date??
I did a complete wipe of the phone (/system, /data, /data/media, /cache, and /dalvik-cache) and reinstalled the rom... and still nothing.
My A2 no longer accepts a chare and continuously drains its battery.
The issue is my own fault, as I used chargers that did not have the same specs as the phone.
Im wondering if anyone else ran into this issue and how they solved it.
I took my phone into a shop. After their diagnosis, it turns out its something wrong with the mother board, and not the charging port or battery.
It would be cool if there were some sort of software fix for this, but probably unlikely.
I got this used moto g6 xt1925-12 and it's having an issue where it's not charging in any normal mode
It does charge in fastboot mode but only up to 70%
There are no charger or cable issues as I already verified it and works with another phone
I am thinking there some chip or control device that is not recognizing the usb when I plug it in in normal mode so I was wondering if I could bypass whatever is controlling it and connect it directly to the battery
If I had a schematic I would try to see what is controlling it and perhaps replace it if that is even available on the market but without that I have to use brute force
So I was wondering if there are any electronics experts or perhaps someone who knows how a usb c is generally implemented in a phone or more specifically in the moto g6
Would connecting the usb c directly to the battery cause any problems ?
Even though you verified that your charger and cable both work with another phone, I would still try different combinations of cables and chargers. Various things can happen to both cables and chargers that render them less effective (a cable can have one internal wire fail, a charger can have a resistor fail, etc. etc.). Also, some devices are more persnickety about the power they receive than others. My GoPro Hero 5 Black was able to charge its battery and interface with my computer through a USB type C cord that didn't work with my Moto G6 at all.
That said, I can't offer much help additionally. Given the cost of a Moto G6, I doubt it's worth hours of soldering to get your battery working normally again. You might want to look into a replacement battery from eBay, but even then, you might still have issues because as you said, there could be a fault with one of the chips that manages charging. Allowing the battery to fully discharge once or twice might be worth trying.
Sorry, wish I could be of more help.

Thanks for the reply and trying to help
The phone I verified with is the exact same model xt 1925-12 so I am sure the charging system outside of the phone is fine I also bought a new battery and just plugged it in to see if that makes any difference which it did not and just last week I replaced the charge port and while that looked a little dirty and was missing one pin on the end which upon looking at a pinout found out to be a ground pin of which there is more than one so of course that did not make any difference
I understand it's a cheap phone I just like to get to the bottom of the problem if I can and perhaps do a little troubleshooting inside the phone
There has to some chip inside that controls everything since it's charging in fastboot mode but not in any other mode
I just have to try it and see what happens

I think I found something that may be a little safer than a direct jumper
I came across a video on Youtube where the guy installed a diode The video was about fake charging so that's not exactly my problem and it was on an older phone with micro USB and not USB C but in theory this may work
There was also another video on changing the ic charge ic on an Iphone 6 which was a BGA I am not even sure where the charge ic is located on the Moto G6 but if it's a BGA I don't want to mess with it unless I have to plus it's probably not even available to buy anywhere so I think I will go with the diode method first and see if that does anything
