Attention!!! I have found a fix for signal problems!!! - Samsung Epic 4G Touch

DISCLAIMER I AM NOT RESPONSIBLE IF YOU RUIN YOUR PHONE. THIS WILL VOID YOU WARRANTY UNLESS YOU FOLLOW MY INSTRUCTIONS. I CANNON GUARANTEE THAT THIS WILL WORK FOR YOU. I'M JUST SHARING THE INFORMATION
OK so as you have probably read in the title. I have found a fix for signal problems on the E4GT! All you have to do is take the back door off the phone. No do you see those stickers on the back. Those are covering up the antennas peel those stickers off DON'T throw them away stick them to something so that you could reuse them and stick them back on the phone for issues if you have to take it to the Sprint store. I have mine stuck to the back of the back door mine still fits on bcuz I have the extended battery.
After you have peeled those off you should notice that you're already getting a bit better signal. You should get a lot faster GPS lock that's what I noticed and it stayed locked on.
Now the next thing you can do is your choice. What I did was get a piece of tinfoil and folded it a couple of times and then cut a place for the camera I'll provide a pic of what mine looks like.
Now stick that piece of tinfoil on there and snap the back of the phone back on and you should be good to go.
Ever since I did that it worked miracles. I no longer have that big of an issue with signal on this phone.

Genius. So you are saying pull off the protective elements of the antennas then short them all together with tinfoil!? For any other people reading you can destroy your antenna this way. They are fine tuned to pick up certain frequencies. Please do not do this. Putting tinfoil will not help. The same thing goes for those stickers you put under your battery. Placebo effect. Op while your at it try sticking a wire into those ports on the back of the phone. Im sure it wouldnt hurt. DISCLAIMER-STICKING ANYTHING IN THOSR PORTS WILL LIKELY SEVER THE CONNECTION FOR WHATEVER THAT PORT WAS GOING TO. ITS HAPPENED BEFORE. ALREADY TESTED DONT DO IT.

Its not actually shorting them. They are protected ribbon antennas. What the foil more than likely does is direct the signal in a way. It may help direct the signal either to the phone or away. Either way, this is still not advisable to do. There are exposed components like antenna interfaces that could be damaged.

Gray are they protected when you peel off the black cover like he suggested? I havent had a need to pull that off. So I dont know if its bare under there or not.
sent from my Provari with a mini rda!

Yep. They are like flex cables.

So does this actually work or not? I'm not gonna chance severing network connections with tinfoil if it doesn't lol
Sent from my SPH-D710 using xda app-developers app

It works just fine for me it will only sever the antennas if you take the back off a lot I've noticed a boost of about 3 bars
Sent from my SPH-D710 using xda premium

Oh and if it doesn't work you can replace the housing on the phone cuz that has the antennas in it. The parts are on eBay for like $12-$15
Sent from my SPH-D710 using xda premium

The housing is not a concern. It is the exposed antenna interfaces on the motherboard. If those get shorted in any way, you will never have a signal again.

I haven't had a problem. The only way it could get shorted is if I actually attached metal to the contacts

charging cable

While charging the phone does it seem like the micro USB charger just seem to fall out
Yup mine does it too, just takes a light tug and it falls out.
Mines actually pretty snug. Doesn't seen to move much at all on me

I think you are just not putting it in all the way... with mine if I put it in softly it just falls out, but a little beyond that it feels like you are just going to go through the phone but it's like a second layer of safety

Drop? Reboot?

Hi,
Do u guys also have it when u drop ur phone (facing the battery cover) from a bit height it reboots?
Even if its from an height of 5 cm
Sent from my GT-N7100 using xda premium
Nope, I dropped mine twice from a height of 1 meter and when I pick it up its still on.

It is an indented security feature.
It happens to prevent data loss.

Now I'm seriously concerned. where do you get your information from? That is a feature present in laptops where there are moving parts like a disk drive. There's absolutely no point in that feature being present on a phone since it uses a chip to store information. The most probably cause as to why your phone reboots is because of the contacts between your battery and phone getting separated due to the impact. Make sure your battery isn't loose and all that the back cover is properly attached.

Just in have tested (on bed of course) drop 5times from 1ft height and never reboot,previously two times device was dropped from more than 2ft height on floor accidentally but never it was rebooted too. i have not read such kind of security features before this on mobile device.
I think it must have loose connection.
Sent from my GT-N7100 using xda premium
I watched a video drop of the S3 from about 5 meters with the commuter case, still on and working ^_^
Your battery connector is loose (on the phone), or the battery connector grid is dirty, so it looses connection when you drop it.

Thanks for the replies guys.. its weird.. ive pulled everything out and then back..it seems ok now :/

I forgot to ask your to clean the connector grid on the battery, if it is dirty of course.

I don't know I watched it in a drop test video.
Correction it was the back cover. It is intended to come out in case of impact to reduce the damage.

Phone won't enter usb mode

For whatever reason, my phone stopped recognizing that it is connected to a computer via USB (nothing in the notification pull down menu to start usb mode etc). I was on slim rom, I tried switching to an old wild by night rom and it still has the same problem. Clearly it's not the rom, so I'm pretty confused. Trying to mount in CWM doesn't work either, and odin mode is not recognized on the pc. Charging via usb works.
Either your wire is busted or the solder joints on your port are cracked. Both are easy to repair.

Hrmm.. gotta wait till I get home to test with a different wire. How does one tell if solder joints on the port are cracked?
Visually inspect them. Its also a dead giveaway if no wire will work and nothing else is wrong with the phone.

I did a little more forum digging and found this old thread: http://forum.xda-developers.com/showthread.php?t=1344882
Sounds like exactly what happened with my phone (weird car mode that I've never seen before popping up; charges but doesnt connect to usb). Looks like you're right about the usb port. Gonna have to see if I can debride the area somehow...
If you are not experienced with or comfortable doing precision soldering, hit me up. Also shine a flashlight into the port and see if the pins are still in place. Bent pins can cause crazy issues.

Soldering is out of my cabilities, mostly because I don't own a soldering device. I do have access to dental equipment though, so I took a look using some 2.5x mag loupes with a light and I saw some some dust and white corrosion. I used a plastic periodontal probe to scrape out the corrosion, small brush to dust the port, and air syringe to blow it all out. Wamo bamo, it's working again.. hopefully it stays working.
Sweet deal man! Glad you got it all back to normal.

Bleh it was shortlived, or at the very least -- finicky. Seems like I may need to replace the port. Do you have instructions for doing that?

Not instructions, but it does require the ability to take the device apart and some fine soldering skills. Not really easy to make instructions for that. It takes a lot of skill to do it.

Tragic Accident! My fiance dropped her HTC One

Ok so me and my fiance went on a road trip to visit my family for New Years. She accidentally dropped it when getting out if the car. It hit on the bottom right corner and dented it forcing the bottom plate up. I was gonna try to fix it DIY style like I fix everything but I want a few second opinions... I was gonna use a press or something to press it back down. Lol any other ideas?

Well...personally I would heat that one up and remove it to be replaced by a new grill. Google the part and also check out a couple teardowns. You might be able to reshape that white plastic once the grill is off too. Good thing she didn't get the glass !

I would take a look at a teardown guide. See if you can get a busted htc one on ebay to replace the back part or just try and bend the section that is bent.
There are some tear down guides on iFixit and also on youtube. Would post links but I don't think that is allowed.
the same exact thing happened to me. Dropped the phone, dented the upper right hand corner. What i did was buy one of those invisible body shield cases and put it on.
I've taken apart a fair number of phones,etc, but after seeing how almost impossible this thing looks to dismantle? Nope. I'll just pay the deductible.

Yeah it looks like a mess. I even watched a video and I would never even attempt to do that, way too scary.

I'm pretty sure you can't take a one apart without causing damage to the metal. It requires a special tool that only HTC has as far as I know.

The one got a 1 out of 10 for fixability on some blog Lol I know not to take it apart since it's mostly glued together.
Sent from my HTC6500LVW using XDA Premium 4 mobile app
It's not glued. Just press fit. It has a series of tension clips on the inside and separating them is near impossible without causing damage.

Actually I think it's both. Every teardown guide I've seen mentions having to heat up the phone to soften the adhesive. Here is someone on XDA that braved a teardown before sending the phone back for replacement anyway:http://forum.xda-developers.com/showthread.php?t=2353895

I saw one where the dude pulled it apart without heat, and showed there was no adhesive at all. Someone said something in the comments about how it'd be easier to use heat, and apparently this guy had done it both ways and the only difference is that using heat makes it hot as balls and hard to handle.

Service/Reception boosting antennas

These do not work, there's many webpages to see this info. They've been sold for years and years and none of them work.
The antenna built into a mobile phone is very carefully designed for optimal reception/transmission and small piece of plastic with gold etch on it won't help, it's more likely to cause issues.

http://www.amazon.com/Universal-Phone-Reception-Antenna-Booster/product-reviews/B000EFNQES
The antennas on the Moto G appear to be bonded onto the back, top and bottom - remove the back cover and you can see a slight raised section on the top and on the bottom edges of the phone.
Seriously, these stickers only work when you stick them to your forehead so everyone you meet can save time finding out what an idiot you are.

I agree, these stickers are a HUGE scam. Don't do it.
