Got a Lemon Epic 4g Touch

The phone is absolutely stunning and a definite winner. It's really sad that it seems that I may have received the lemon in the bunch. Hopefully this is an isolated issue but my phone starts having serious technical problems when attached to a charger. Screen unlock is hard to orchestrate, applications and contact lists and settings menu's open on their own and even attempt to execute their own commands. The phone is fluid and beautiful until u want to charge it and use it at the same time. I think I got a lemon. I've already processed an exchange with Wirefly and they were extremely responsive and immediate in processing my request. I tried doing a factory reset to no effect. If there are any other trouble shooting suggestions I would appreciate it. It is really a shame that this phone may be a lemon. I searched and read about similar issues with the previous epic when using an aftermarket charger. Everything came in the box with the phone here, oem. It is possible the charger may be bad but I might as well exchange all of it just in case. Could be a slight short or something that bad.

Go exchange it.

nah...
look HERE
already being discussed. its a galaxy s2 bug. There are a few fixes floating arounf

Did you have Kies air running in the background?

No I've closed out the apps and it's still an issue, I've also tried a factory reset.

Known issue, common to a lot of phones. Can be fixed with software. Doesn't seem to happen over USB charging and it seems to happen much less severe the closer to 100% you are.
Not a lemon at all....it mildly annoys me.

Thank you for that link to similar issues with international GSII users. I am going to go and test it out on various outlets throughout the house. I will also try using various settings with SGS touchscreen booster from the app market. If anyone else experiences this please let me know. Honestly, after my exchange if this is an issue with the new phone as well I would still probably keep it. I should also test whether this is an issue during regular USB charging. I'll be back with the results.

It's really really sensitive though, i mean it just goes nuts.

Yeah, some outlets/power systems are likely worse than others. Stick with USb charging if you don't need it charged rapidly. I've had no problems with that so far.

Problem consistent on four separate outlets at all different settings using screen booster app. USB charging does not have this problem though. I may just have a sensitive phone. It would be nice to confirm with another epic 4g touch owner though before I carry out the exchange.

My friend's E4GT had a picture in the gallery of a Best Buy employee flipping off the camera and to make matters worse, the device will not charge...

The phone is downright sick though, a long term keeper. Featherlight, it feels surreal when you first receive it with how wide, long, light and thin it is, so surreal it feels like a fake phone. So thin and long the first thing I thought was this thing looks like it could snap in half. But my first Evo came with a bad pixel too so I guess with this one I'll try again. Honestly, I'm keeping the next one no matter what.

My HTC charger actually works fine. My Samsung charger is the one causing the problem

This is interesting. Here are the results with using my HTC Evo charger on it compared to it's own.
HTC Evo Charger with after market USB Cable - WORKS PERFECTLY
HTC Evo Charger with Samsung USB Cable - Moderate problems
Samsung Charger with Aftermarket USB Cable- Severe Problems
Samsung Charger with Samsung USB Cable - Severe Problems
It's own equipment is doing it. Makes no sense. Should I keep the phone and use my Evo's charger?

retesting, HTC Evo charger with Samsung USB cable seems to be functioning well.
The culprit seems to be samsungs charger.

i wish they would have lined that sprint one with felt.....
coming from seidio cases the non felt ones really scratched up the phones bezel so ill pass....looks like im gonna have to find a silicon one thats easy to take off

only issues i have is with the samsung charger so i just threw it in the drawer and used one of the 20 other usb chargers i have...

Yup did that too, threw that little sugar cube of a charger in the box. Using my HTC TP2 charger with no issues.

I've been using my old blackberry usb cable to charge mine since I've got it and I don't have that problem.. try using a different usb cable
Tapatalkin' it from my Epic Touch 3g

I notice the same random behavior with my phone when connected, but I really didn't freak out I'm just using my other charger from my first epic and problem solved,it's charging and working at the same time ;-)

The charger that came with this phone looks like such a piece of junk that I really refuse to use it! My photon charger has been working flawlessly on this phone.
Sent from my SPH-D710 using Tapatalk

similar weirdness here too... it wouldn't charge. had it plugged in to the wall outlet and noticed the charging light was not on. unplugged the cord..unplugged the usb part and plugged back in to no avail. then i powered off the phone then plugged it back into the wall and now it's charging. i hope this doesn't get worse. if this is it, the maybe i can deal with it. anyone else have this happen?

Slowness In Touchscreen While Charging

I found a kernel in ATT Note that removes ghost touches, so that might be just the thing that slows it down.

Mine gets slow too..I'm got beastmod5 with darkside kernel ..
It lags crazy when using adownloader

What was the point of this thread?
And yes I am aware of the issue u speak of being as it is widely known that the phone is less responsive to touch while on the charger.

I found using crappy chargers will really show this issue.
With one the screen is unusable.
It sounds like it converts over to mains power to allow the batter to charge, however the battery is sucking the majority of the power from the line so there is not enough to fully power the unit...

That the developers can contact him, or they can just take off the piece oof code, and there, we have good working touchscreen, it will also be ffaster and more responsive always.

Alot of phones do this my g2x did this also

Because the kernel makers add the water proof touchscreen optimizer, something like that, that makes it able to use while water is in your screen. But if you disable it, it would be a lot faster.

these strange issues are usually caused by cheapo chargers
it doesn't do this when you charge via a computer USB or wall using the original stuff
a decent build quality of china made wall / USB chargers will also work fine.
it all comes down to the quality of the power regulator in the charger

Well, it happens to me in all ports, in all USB cables.

Happens to my GS2 on *any* custom ROM with the stock charging pieces. The stock firmware never has touch-lag when charging - ever. YMMV.

This is wht I'm trying to say
For those a bit confused as to what 'Ghost thouch' is, and why it is removed:
Samsung added a bit of code to the touchscreen driver on the non-intl version of the note to detect 'ghost' touch input events, similar to the raindrop detection on the original Motorola Atrix (and others). While a nice idea on paper, this had un-intended consequences when trying to perform multi-touch input that continues longer than around 5 seconds; such as playing some games. It is now disabled in this kernel.
Edit: There also seems to be a pleasant side effect that I hadn't noticed... keyboard input is improved. Makes sense I suppose, since now there isn't this constant check for false touches slowing things down. Let me know if you see this on your device.

I have this issue too no matter which rom is being used or which charger im using. If there is a way for me to disable that "water drop" thing im sure many would take kindly to that.

Its a samsung thing. I've had several samsung phones and the touch screens always goes wacky while charging

Charging Issue

Hi guys,
i have some issues with charging my inc2.
it is not accepting any charge anymore, tried diffrent chargers, cables, even on my pc but nothing. The orange charging LED just flashes slowly on and off...
Any ideas?

Need to replace phone or replace charging port.

Yes, unfortunately it is a known hardware issue. Over time, the charging port starts coming loose. Like mentioned above, you CAN fix it yourself. There are video tutorials on YouTube and the replacement part can be had for under $10. If your device is still under warranty, Verizon will replace the phone. If it's not under warranty (or if you just want to give it a go), the port replacement process is pretty straightforward.

I might give it a try. Does anybody have a video or a link?
The weird thing is, that the battery is discharging very fast, could it be just a bad battery?

Could b the back door on your inc 2. I believe you need the back door on to charge cuz it goes thru contacts on the back. I dropped mine one day and charging and getting signal was almost impossible till I figured that out and bought a new one

Ok.
Seems to charge now. Won't touch it until it is full. After that I will check what is going on.
I don't know where this issue came from.never dropped it nothing. It was even in a Otterbox
Sent from my GT-N7100 using Tapatalk 2

The issue stems from regular use. The charging port is essentially held in place only by the connections to the board. Repeatedly plugging and unplugging the power cable causes it to break over time.

actually just replaced the charger port on my incredible 2 today. It really wasn't that difficult at all. If you have any questions feel free to PM me

yeah it has to be replaced. happened to me last month. It's honestly like the worst flaw with this phone

Def need to replace it. Same issues I was having at one point with it randomly taking charge. I found that if the charger is plugged in a held a certain level ( i placed the phone on a flat surface with a book under the cord for leverage) it would charge just fine.
If you are rooted and sending back, make sure you revert to stock to avoid any annoyances.

I've managed to solve this issue without messing around with the phone's innards (the last time I did it was a disaster and I was forced to buy an entirely new phone). It's not pretty, but if you twist a rubber band around the micro usb end of your charger, plug your phone in, twist that same rubber band around the phone itself, and make sure the connection very tight, you might get some more life out of your charger port.
Ugh. I can't wait for my upgrade.

Nice name there Dave.

While, I give you major kudos points for MacGuyver-ing a solution, that's more of a quick band-aid than a real fix. I could imagine having a rubber band around the phone could potentially hinder usage.
But hey, way to think outside the box! :good:

Thank you. You're telling me. Do you know how hard it is to use a touch screen with a rubber band across it? Oy.
Right. The caveat here, of course, is that this technique will only help charge your phone until the charging port becomes so disconnected from the board that no amount of force will reestablish this contact. And this will inevitably happen because you're going to keep plugging and unplugging your phone from the charger which is what created the issue in the first place.
If you know you have big, sweaty, idiot hands (like me) that are going to destroy your phone if you take it apart (like me) and you can tough it out: more power to you. The other alternative is to buy an external battery charger and a second battery. The disadvantages here are pretty obvious (e.g. you have to carry a second battery around; if you forget a second battery, you can't ask another Android user to borrow their phone charger, etc.).

Charger Making High Pitched noise

I always knew I had a better hearing capabilities than the average person because when we were studying different sounds frequencies in class I could always hear the frequencies that my classmates couldn't Now that I have my new GS4 and want to charge it Im hearing an extremely high pitched noise... that stops when i unplug the charger... I dont think im super human so im wonder if anyone has heard this or knows exactly what is causing this let me know... Thanks!

try leave the device in other room when charging

I know I had that same problem with my Galaxy Nexus charger. It only happened when I had the charger plugged into the outlet but no to the phone, it went away when I plugged the phone in... Who knows... it never affected functionality.

It's SATAN.

I've noticed the same. It's not superhuman hearing, I have terrible hearing from being blown up a couple times and got the audiology tests to back it up, but I definitely can notice it if I'm within 3-4 feet in a quiet room.
It's nothing to be worried about, I've heard the same from other chargers before. Probably something to do with Samsung upping their chargers to 2A.

There are certain Frequencies that people cant hear.. My mother or my sister couldnt hear it... Im not saying im super human just that everybody cant hear it... but yeah ill try to ignore it... its Similar to the popular "Mosquito Ringtone" of 2006

Does it sound like coil noise ("capacitor whine")? Defective/damaged/cheap/Poorly-designed caps make a distinctive high-pitched squeal.
Sometimes they'll function like that perfectly for years, sometimes they'll short out in a matter of minutes. Either way, I'd ask for a replacement.

Its gota b an inductor coil. Happens all the time to chargers. You can get a replacement since it wont last as long as it probably should. No problems short term.

power/charging issue

ive been having a problem with this phone for a while. it has a problem with turning on and statying on. i will set it on charge while its powered off for atleast two hours, but as soon as i turn it on it will last for about 5 mins and turn off.
i first replaced the battery and it has the same problem. so i replaced the charging port and it was working fine for a few weeks and now its back to the same issue. i cant even get it to charge now
so just trying to figure out what kind of other components it could be

Disclaimer: You're at a more advanced level than I am. I've never done phone repair, and I don't know enough about phone hardware to say if there are other components that could be responsible. I'm a software guy.
That being said, I'll chime in with what I do know, on the off chance that it's actually helpful.
When computers get too hot, they do an automatic thermal shutdown to try to prevent permanent damage. I assume smartphones do this as well. You're on XDA, so there's a good chance you like to tinker. Did you overclock the phone? Overclocking generates more heat, which could potentially lead to a thermal shutdown or permanent damage. Or you might be using or storing the phone in a hot environment.
Have you tried using a different charging cable? Maybe the cable or its connector went bad. You could also test the cable with a different device. Maybe the wall outlet, etc went bad. Did you check the connectors that the battery attaches to, to make sure they're clean?
When you opened the phone to replace the charging port, maybe you didn't put it together quite right, so over time something came loose or got pinched. Desktops and laptops use various types of adhesives such as thermal paste, and computer technicians have to remember to reapply new adhesive when putting a machine back together. Maybe phones use some adhesive too, and maybe you forgot to reapply it?
Hopefully someone more knowledgeable about phone hardware will chime in, but the Incredible 2 section of these forums has been a ghost town lately. That's why I'm giving my two cents. If it were me, I'd just buy a new phone.

well i greatly appreciate your lengthly response. to be honest, it is my mothers phone, which is why i want to try and fix it. i gave her an iphone so she really doesnt need this phone but i would like to figure out what is wrong because i do like to tinker with things. i have tried different chords, wall outlets, usb ports on the pc etc. i will reopen the phone to see if everything is back together, because thats the only thing i can think of from what you mentioned.
thanks again. if anyone has had a similar problem, let me know

sounds like you're either having a battery issue or need to replace your charge port on your phone. its a really simple process all you do is order the port from like amazon or ebay and the old one on your phone just unplugs from your phone circuit board there actually is a tutorial forum in the development page for the droid incredible 2 that gives you instructions on how to do this. hope this was of some help to you and if so please click thanks.

The OP already tried both of those things.

Oh ok yeah i just noticed where he put that. Hardware problem maybe. Im more into software myself than i am hardware.

MINE TOO! Omg
This... it's too much. Okay, a month ago the damned power button got too hard to press in, which should have been a warning that the hardware was getting faulty I suppose. But I downloaded an app that let me use the volume button to turn screen on/off. (I won't say which because I half-blame it, unfairly, for killing my phone
(Sorry, I'm still —mourning! the death of my phone I guess.)
The app was an ugly solution, I guess, but it worked. (I couldn't turn the screen off easily, so I set the screen-off to 10 seconds.) And I hadn't used screenshots in a while so that was no big deal; and my ROM could get me to Recovery easily enough, so screw the power button, right?
But then last night, my phone STOPPED CHARGING! I did a batt pull, tried new cords; turned off every useful app. I even went back to stock ROM, which (even though plugged in) left me with 20% batt. Might as well have bricked it, I guess.
Nothing worked. I was able to turn bluetooth back on so I could use my Air Droid acct to get my on-phone pictures, at least (everything else is safe on the SD), and then I charged it overnight in the wall and hoped for the best.
I was pretty thrilled to wake up to 100% charged! —For a few minutes. As soon as I unplugged it, it started discharging fast, and then not even the wall charger stopped it from discharging.
After brooding, for a few hours, I called Verizon tech. The tech (VERY nice, admittedly) said my Dinc2 was just dead. (Damn they're good: he was more sympathetic than a doctor delivering bad news!!) —But I feel so lost. He offered me a DNA or a Dinc 4G (and some motos and crap), but said my Dinc2 wouldn't be worth fixing. He said the power button alone was a PITA, but the dongle thing you plug the charger into was likely the problem, AND it might be the battery. Maybe he said other problems, but ultimately he suggested some pre-owneds he had for sale (I'm trying to keep my unlimited data plan), or try PhoneKarma.com. (He said he didn't recommend eBay, where they have Dinc 2s, but I'm not sure why.)
So ...do Dinc2s just have power issues after (?) 3 years? I guess that's a pretty good lifetime, but boy is it depressing. (I know — hooked on a damned phone. #Sucks.) I mean, it would be stupid to fix this one, or buy another one, right?

@Trebuchette, no matter what machine you use, rechargeable batteries do not last forever. Order a new battery from Amazon or eBay and you should be fine. They're pretty cheap and easy to replace. http://www.amazon.com/HTC-Incredible-6350-BTR6350B-Packaging/dp/B0064SI3QA
A case might make your power button easier to press. The OtterBox Defender is an excellent case that you can get for $15 used (very good condition), if a new battery successfully fixes your problem.

Hey: might be worth a shot! I did try another batt, but it was older too. And I didn't think of an otterbox at all, tbh. Thanks! Might be worth a try!
Hey: does it matter much if my USB cable is LG or whatever? I tried several different USBs too, but I'd been using this LG one (no idea how!) for probably about a year.

No, the brand of micro USB cable should not matter. It's a technical standard.
Don't buy a case until you've verified that a new battery actually fixes your problem. If a battery doesn't fix it, it's only a few bucks lost. In that case, I would then get a new phone.

i just came back to this thread after i basically put the project on hold for a while and wanted to see any new suggestions. so after leaving the phone alone for two months, i pluuged the phone in and i saw that orange ligh indicating it was charging. so far so good, im not using it as a primary phone which is good, but that would be my suggestion is to give the phone a rest for a while
EDIT: yeah scratch that, its doing the same **** now
