[HELP] Poor reception after repair - T-Mobile Samsung Galaxy S 4

So, A week ago, I broke my galaxy s4 successfuly damaging the LCD. No Big problem, Ordered a used LCD from e-bay and carefully took the old one off and installed this one. Boot up the phone and wallah! it works fine. EXCEPT! The stupid thing doesn't have reception half the time.
Sometimes its stuck on edge with full bars, sometimes its got 4gLTE but no bars, Sometimes its got a circle with a line through it saying no service and sometimes it has all bars and 4glte yet it still says searching...WEIRD.
So I tore apart the phone again up till the board and carefuly started inspecting everything , looked normal. Looked on the rear frame. A plastic piece where it says R1 was coming off, so I took it out completely and re-glued it back on. Turn the phone on and same thing. I did lose all the screws during the repair.... silly me lost the magnet they were stuck on and have not been able to find it. So unless the screws act as antennas which is possible, it is losing service all the time. I suspect the plastic piece where it says R1 is the problem and have ordered a new piece due to arrive on monday next week. The only problem is I just moved and am expecting quite a few calls for job interviews. Can't risk losing a great opportunity.PLEASE HELP ME WITH ANY ADVICE YOU CAN GIVE!!!! thanks!

If you're having issues with the reception I recommend having a look at the micro USB/charging board. I swapped that part out before after breaking it and had horrible reception. I then purchased another one (actually meant for my phone) and all was well again.

Menu button goes off by it self

I always had a problem with my menu button going off at random. So if anyone else has this problem here is a fix. U will need to open up ur phone and thanks to Samsung with out any void stickers. after removing the screws the bezel around the screen is just held in by clips. So you be left with glass and the board. Clean around the rim of the glass should have little dirt build up on the rubber sealant. Also I booted up with out the flex cable( linked to the touch button) connected and once booted up reinstall every thing and it work no more random menu pop ups

Good info. But i thought it was caused when in low signal areas. Actually, i got my replacement refurb phone a couple months ago and it never had that menu problem until a week ago. So the dirt thing is possible
I just got this phone last week (used) and it has done it constantly when in low signal areas, like my job. However i put it on wifi at work Friday and it stopped. So i think it is related to poor 3g signal. Just my thoughts based on my experience.

menu button
I had the same problem on a brand new phone. It was 1 month old. It had it happen to will on wifi or will I
had full bars. I think the dirt problem is more the problem. I work in a shop with alot of dirt on the air.
Thanks for the info. I will know what to do if it happens on my refer phone.
if its a dirt issue why the need to reinstall software?
I cleaned my phone yesterday. Bought it from a chick that wore a lot of make up so it was pretty dirty. And so far no menu button misfires. May in fact be the dirt issue. Odd that it was really only going off during weak 3g signal times.
WOW, universal problem
I have been experiencing this on my new device for some time now. I thought I was alone but apparently others have it to then. Mine will go haywire all of a sudden to the point where the menu pops up and disappears up to 20 times by itself leaving the phone unusable and making the other haptic buttons non functioning. Usually requires quickly turning off the screen and popping back on. Drives me absolutely nuts to the point that I de-rooted and went back to absolute bone stock only to still have it happening.
Has to be dirt related. I thought maybe there was some voltage or heat problem that was causing it to fire. Has anyone had any luck fixing it without tearing the phone apart?
I want to smash this phone in low signal areas!! My NS4G gets better signal than this does in bad 3g areas. In California where I had full bar 4g this phone was perfection but once I got on the east coast (especially spots in NYC) I get so damn frustrated!!
I sure wish it was dirt causing it but I got it when my phone was new when I was LOS testing in dead spots the first month I had the phone

Mine has been doing it since I got it. It is a refurb though as I bricked 2. The 2 previous phones didn't have the issue and it only does it when switching from 3g/4g to wifi or vice versa, or while switching data back on after a call. In my case it's definitely not dirt.

Same always want to throw my phone at the wall when I'm in a low signal area and the menu button goes crazy!

will be trying this to see if it fixes it for me as well
I have this same issue with mine and will be trying this when i get some time. It's very random and very annoying.
have had this happen on 2 phones, finally on my 3rd replacement last week and it has been good so far....
This keeps happening to my phone, only most of the time it's the search button. Low-signal areas mostly, connecting to wifi stops it completely. I think it may have to do with using non-samsung chargers/cables.
Mine alternates form the menu button to the search button. Both equally annoying... I must have some special dirt in my phone

I notice it more in low-light situations than I do in low-signal situations. When I'm connected to WiFi, I don't see any lessening of the phantom menu button.
U guys could also try the second part which is to boot up without touch button connected then when booted connect it back via flex cable on the bottom... good luck
BTW opening ur phone isn't so bad no void stickers and after screws are just clips

Damn guys I thought I was alone with this problem! I swear, I don't care how great the S3 is. If it has the same behavior its getting returned immediately. My GNex doesn't though so that's a good sign. I wonder if we could add menu buttons to the screen and disable soft keys and maybe it would get rid of this behavior. I have to see if a dev can make that happen

Well, I'm gonna have to edit my comment from earlier in the thread. After about breaking mine in half and throwing it out the window yesterday, I decided to try taking it apart and looking around. I didn't see any dust, but once I reassembled it, the problem has not returned. It usually does it immediately when it reboots and continues until it has acquired a signal. I've tried my best to get it to go crazy and so far so good. Those having the problem may want to give it a try and see if it helps.
My brother in law who is rooted on Blue Kuban, My Sister in law who is completely stock EL29 and my self also rooted on Blue Kuban all experince this problem. we all have launch day phones. def seems to happen more for us in low signal areas. so annoying. for those that took the phone apart is there any chance of dust getting in and being seen or is it no big deal?
thanks

[Q] 3G network not working after drop

Hi,
I would like to ask for help and/or any suggestions that might lead to the solution of this problem.
Basically I was skating and had an accident and the screen cracked, which i got replaced, but then at the same time the network was connecting and disconnecting continuously. It sometimes shows the bars like there is good signal but i cant make calls or send texts, as soon as i try it shows a cross and no signal.
I tried everything from factory reset to changing the Radio/RIL to changing the rom. After a while I switched it to GSM only and it worked!!! So now the phone works on "2G" only which is annoying as the internet is quite slow. But as soon as i switch to Auto between GSM/WCDMA it goes back to doing that problem.
I would appreciate any suggestions, It might a damage to the mother board, but everything seems to run brilliantly on the phone.
Hi I've encounter the same accident too, but luckily I'd use casemate barely there, so it proof had protect my phone. You may need to sent for repair, as it sound so serious.
run an RzrU on the phone and send it to HTC or your carrier for repair. Definitely one hundred percent hardware failure

Is the bottom plastic cover cracked from inside or damaged in any way?

Quality of certified like new replacement from VZW?

Hey all,
Having some charging issue with my device that will likely necessitate a replacement device. I've been hesitant to make the move given the quality issues of CLNR with Verizon in the early months of the GNex existence.
For those who have recently received replacements, did you encounter much problem? It seemed like the issues were mainly related to the screen or reception issues. I had my Gnex since day 1 and never had any dropped calls or weak/fluctuating 4G signal. I'm hesitant to give it up!!
Thanks in advance!
I just got a replacement 2 weeks ago and mine has been great. No issues at all. But every device is different

Its probably the charger cable,battery the USB port is broke. I suffered similar issues with a CLN HTC incredible. Try switching batteries cables or adapters. If all else fails take it back
I had similar issues with my original galaxy nexus after owning it for 8 months. The replacement they shipped me the ear piece on it didn't work. Sent that one back and the one after it I've had for almost 4 months now with no problems. A lot of it is just random bad luck, if I was you I'd send the old one in and hopefully your luck will hold up.

It might be a good time for a refurb, considering VZW just retired the phone.. Is it possible the remaining Gnex stock was pulled for refurbs?
About two weeks ago I got mine replaced by verizon due to my phone having charging issues as well. I went into the store, didn't call before hand.
I had flashed back to stock before i went in. Told the girl there that it wasnt charging right and i have multiple batteries and they all do the same. she went to look up on some database if others were reporting similar issues (there were none). after giving her my phone number and 5 minutes later she said a replacement is on the way and to mail my old one back in the same box (shipping was paid for)
I was very pleased by how quick and painless it all was. She never touched or looked at my phone at all and asked hardly any questions. my phone also had a chip in the screen (about 2 cm at the bottom right, no cracks though)
the replacement phone had a sticker saying "like new" replacement but it was absolutely pristine. absolutely 100% perfect cosmetically and works great as ever (screen colors seemed better than my original one imo).
Thanks for the heads up. Went ahead with the replacement. Will wait and see.

Just realiezd there's a scratch on the screen of the device I'm sending back... Any advice on what to do? I don't wanna get burn... I heard that VZW can charge an arm and a leg for returns that have damage...

Nothing to worry about. Mine also had a chip in the bottom right corner (about 1/4 in long and 1/8 in high) as well as light scratches near the top of the screen. Luckily the chip did not develop a crack, but none-the-less, the lady at the VZW store didnt say anything of it even when i pointed it out, and my return was accepted with no charges incurred.

Really weak wifi signal and screen sensitivity issues

So my note 2 has really really weak wifi signal, I am 20 ft from the router with only 1 wall between us and the wifi keeps timing out and sputtering.
I have turned off the power saving wifi and replaced the drivers with the ones from 4.1.1, I have tried numerous kernel and roms.
Is it time to open up the phone to look for a hardware fault?
Also screen sensitivity on the bottom right of the screen is terrible, trying to hit the back space key can be a nightmare at times

Found the wifi fix
I just figured out what the problem is, the wifi antennae in the case was buggered! I ordered a new back of the phone and replaced that and the wifi is fixed!!! I had a feeling that was the cause of the issue but I couldn't be sure till I replaced it. The wifi antennae is above the power button, with the back off you can see it as the long piece of plastic that is stuck in on the very edge. I had to buy a whole new back - it was only about $11 shipped. But it solved all my wifi problems.

I took the main part out of the chassis frame and found that the spring contact on the PCB (which is supposed to touch the wifi antenna on the chassis frame) wasn't springing up. I bent it up so it matched the profile of the other spring contacts and put it back in the chassis frame and all was well. My suspicion is your wifi antenna wasn't broken (it's just a bit of metal so there's nothing to break, really), just not quite touching the spring contact.
Same Problem

Good day I am assuming that this is the same thing that has happened to my note 2 it had a fall, everything else is working fine just the wifi signal drops when I step a couple feet away from the router so can I ask for a link of where I can purchase the same part you are speaking of or a picture of where the spring contact is so I can try just bending it up please
Yeah mate when my wife comes home with her phone I will be able to take some pics of my phone and post them up

[Q] Radio/Antenna Repair Issue

Dear folks,
One night I reached out my hand while sleeping, touched a glass of water (which fell over) and my Galaxy Nexus GSM got wet. In the morning I dried it (*no* hair dryer, just a vacuum cleaner and a radiator), and it still works like a charm. With few exections: Almost no signal anymore. Most often no signal, sometimes weak signal, rarely full H+ speed.
In my flat I have no radio at all (-110db if that matters). No speech, no data.
Outside I may have luck, I may not. Sometimes I get almost full HSDPA+ as stated, but most of the times with "standard" covering just no signal or a really really weak one, where my old HTC Hero (T-Mobile H2 Touch) and my work phone (Nokia 31xx) have full(!) radio signal. Embarassing.
Speaker was damaged, too. So was the USB port (not charging when switched on, no sound, wrong headset recognition).
I decided to repair it myself. I did this before many times with my old Nokia 3310, and ifixit.com suggested, it's not that hard. So I went to eBay and bought a new speaker part (that more bulky part at the bottom of the disassembled phone).
Well, this fixed the speaker/headset and the USB issue. Hooray! But my radiosignal was still bad.
So today, I replaced the antenna mainboard (L-Shaped). Well, this fixed… nothing at all. I still got bad radio (at least it's not broken down completely). Now I wonder: What could I do next? Flasing radio firmware has no effect either (I think, I tried three or so). Is it really because it got wet? Sth else to replace?
I'm looking forward to any suggestions on what to do next. If you need any information, just ask.
Thanks in advance.
I'm sorry I can't provide pictures atm, but I only wrote 5 posts or so.
