Hi all,
I've been having kind of a strange issue with my Galaxy S4 SGH-1337M. I'll start off with a bit of background info. A few weeks ago my phone started having problems charging, so I replaced the charging port last week. Shortly after replacing the charging port, my S4 started having problems connecting to WiFi and Bluetooth. It's a little odd though. It still connects to WiFi networks occasionally, but when it does, its an extremely weak connection and drops almost immediately. It's the same story with the Bluetooth. It connects fine, but music playback stutters with speakers and my car's stereo. I've already taken it apart again to see if anything looks damaged or if the WiFi antenna was disconnected, but everything looked normal to me. My device is running Android version 5.0.1 and isn't rooted. I really don't know what's going on, and any help would be greatly appreciated.

Try a Wipe data : go in recovery mode and chose delet alla user data.
NB : All you're Data will be erased, need a backup if you wanna keep it.
Good Luck

Hello,
u can go heare ==> http://forum.xda-developers.com/showpost.php?p=50787570&postcount=2549 . See how to flash your modem, but first you need to know your modem's version ( ie : I337MVLUGOC4 or higher...) to do so, go to your dialer and type : *#1234# your modem version is called CP, google it, download it , flash it with odin, reboot and see if it's working.
If the wifi started after changing the charging port, it could be a loose connection somewhere or there is something wrong with the replacement charging cable.

That didn't work either. I also tried flashing the stock rom, which yielded no result.

I actually tried the old charging port to see if the issue was with the new component, but I still had the same problem with the old connector. I've checked all of the connections and everything, at least to my eyes, appears to be connected securely.
It's not uncommon for the wifi chip on the s4 to stop working. I have two motherboards sitting here that work perfectly except the wifi.

Okay, well I guess that's what happened then. Thanks for the suggestions everyone.
There may still be hope. Where did you get the replacement USB flex cable for the phone? I still say it could be the cable if the replacement was not oem.

I bought the USB port on eBay. The description claimed that it was OEM, but I don't think I would know otherwise. Like I said though, I have already eliminated the new flex cable as the culprit becasue when I reinstalled the old flex cable, the WiFi and Bluetooth were still broken.
The phone has the correct imei? If it does, then the wifi chip is probably defective.

Anyone else having problems with their phone freezing or slowing way down while the charger cable is connected?
I tried the wall-plug as well as a regular PC USB slot, but still have the same trouble. I tried changing between Active-Sync and Data when connected to a PC, but that didn't help.
It happened with both stock ROM and NRG's April 14th ROM.
Maybe I just need to ask T-Mobile for the "ID 10 T" code?
---Edit---
This only happens if I have the phone connected to any USB connection than the official charger.
It is still an issue when sync'ing, but otherwise charging it properly helps!
could be hardware related may have to go to tmo =/

Ok
so for the last couple of days I've noticed that when at home, if I turn on the HD2's Wifi, my entire home network stops working. The router can no longer be accessed, even by wired Ethernet.
I figure it was a router issue, so I bought a newer better one by a different company - and what do you know: The same problem persists! As soon as I enable WiFi in my HD2 the router becomes unaccessible - and as I turn it off, all is well again.
I'm a computer technician, an MCSA and usually pretty good with those things, yet this issue baffles me. What on earth could cause that?
No other WIFI devices cause this issue, only my HD2.

What is the radio firmware version on the phone and what is the make, model and firmware revision of the router.
2 IT engineers are always better the one
My older router (with same problem) was 3Com 3CRWER200-75.
I replaced it with an Edimax BR-6524N. Same weird issue.
Both have latest firmwares.
My phone radio version... To be honst, I don't know how to check. My ROM version is 1.48.405.2 (71294) WWE - which is the stock rom of the Israeli version as supplied by Newpan.
Also worth mentioning, this didn't happen until a couple of days ago. Everyting was fine for months with the same exact configuration. SOMETHING must've changed, but what?
And how is it possible for my phone to kill two different routers?
I have the same problem with my laptop when running windows 7 but not linux....seems too me at least my problem is a driver issue.could be the damned for you too possibly. Was there a possible divert update on your phone?
I do not have an hd2 so I am not sure.
Edited for auto correct mistake

You check your phone radio revision the same way you check your rom version. Go to settings, about phone, software information and look for the line "radio version".
Your actual rom version is quiet old and if you are still using a stock rom then you may want to have a look at the htc website for your country and see if you can get 1.66 rom or newer.
I personally have never experienced this problem but i always use linksys or netgear networking equipment. The linksys router i have at home i've had for many years (it's a wrt54g v2.0) and it still works perfectly even though it's cpu and networking chipsets are overclocked and it runs a custom firmware.
Well, the ROM is the latest available for my country :-(
But anyway, I managed to solve it by deleted all my wireless preferences and just 'rediscovering' my home network from scratch. Surprisingly that worked and solved the problem, even on my old router.
Now I'm wondering if I should return the new one and stick to my trust good old one, or stick with the new one? It was pretty expensive, and I don't really use an N wireless connection anywhere anyway, so... What do you think, XDA?

You have no need for it, get your money back.
the hd2 is capable of N speeds. You just need to enable it in the registry. Personally i would use the old one till it dies and keep the newer one in a box till then but the choice is yours
The newer one is a lot of money I spent for something I didn't even need eventually. I'll be turning it back, I think.
Thanks to all who helped You guys rock!

great to hear that you've found a solution!
A thought came to mind while reading this thread.
Wonder if it's possible that a certain radio file/setting on your HD2 might've been corrupted and instead of generating the usual wifi signal, it could've generated a signal on the same frequency that completely jammed you're router signal?
Similar to the radio jammer units available in some countries that can be used for GSM, Wifi, etc... just a thought!
Im glad you brought this up because I had the exact same problem (accept I could connect via ethernet just wifi went dead), almost brought a new router after spending 2 days trying to set it up :/ It wouldnt allow anything to see the router wifi wise let alone connect to it via wifi. I havent turned my wifi on the phone since then but ill try reseting my settings later to see if that works. I didnt wanna risk screwing the router over lol. Im on stock 1.48 rom and radio on o2 as well

That's an interesting thought, and if it's true - reversing it could be a tool for evil - just imagine being able to shut down networks just like that...
Anyway, I'm glad my issue was solved. That Edimax N router is really expensive, and I like my trusty old 3Com way better.
My N*kia n95 used to f*ck up the router like this sometimes
My Galaxy S4 Google Edition has randomly stopped connecting audio for calls in either direction. I have already tried all solutions I could find on the internet and this forum, including:
Reboot the phone
Check audio settings
Factory reset
Install multiple different stock firmwares
Install multiple modem versions for my phone
Test calling with other apps
Change type of network (GSM/CDMA/Global/etc)
Opening and cooling the phone
New SIM card
New carrier
I have determined that:
The calls work after leaving the battery out or switching batteries for about 2 calls before it quits again.
All speakers are working, but no audio ONLY during cellular calls.
Texting/Data works and calls on this SIM card work in other phones.
Calling DOES always work ONLY when using a bluetooth headset
It appears to NOT be a software issue, but I am not ruling that out.
Would anyone have an idea what piece of hardware could be broken? Any last software suggestions? I will be trying to sell this in a few days if no one knows anything else I can try.
Well the only thing you didn't try is a different simcard.

I just tried it and no difference. By extension, the new SIM was also a new carrier, so it was not related to that either. Thanks for the idea.
Same EXACT Problem
Not that this helps you at all, but I have the same exact problem. I have tried most of the same "solutions" you have tried as well, also to no avail. I have tried countless ROMs, reboots, Odin flashes, etc. What gets me is that once in a while, after installing a ROM or using Odin to go back to stock, I'll get my call audio back for a day or two. Eventually, and without apparent reason, the call audio goes away, and I'm back where I started.
In fact, I was about to write my own XDA post, but then I saw yours, and figured it would suffice.
Good luck. I hope someone has a solution out there because I'm at my wit's end.
Correction: All the same except that my phone is actually a MetroPCS SGH-M919N. Supposedly its the exact same model as the i9505.

Well, good to know it's not only the Google Edition. I believe the other threads I saw were from other models, too. The S4 must just have a cheaply made/defective part.
I've added one last observation to my list. I will probably make a swappa boneyard listing in a few days if anyone is interested.
Hi ,
Not clear if you guys have custom roms or not...
I seen similar problems like that in I9500 models and most of the time the problem was modem related..did you try to flash/ reflash a modem ( new or same) ?

I believe both of us have custom roms (and have tried flashing stock), and we have tried flashing a new modem (old and new). Although, since calling partially works, I will try a few more modems and report back.
Hello. I have a Samsung s4 i9505.
I changed over the Lcd screen and digitizer.
Now my WiFi is working but the range is very poor. About half of my other Samsung devices. Before I changed the screen it would work in the lounge room. Now connection times out or fails to get an IP address via WiFi.
I'm pretty sure it isn't the router.
I've tried reflashing the stock rom both 4..4.4 and 5.0, with Australian rom.
Now the WiFi comes up, will work within a close range and full speed but from a normal distance is not working.
I've opened it up and everything seems connected and intact?
Is it worth getting a new WiFi antenna? Or may I have damaged the motherboard.
Any suggestions appericated, I'm going mad.... Lol

Did you fix the lcd and the digitizer by your own? Or did you go to the official service of samsung?
I did it myself. Have done it before on the same phone with no issues.

Here's my thread: http://forum.xda-developers.com/galaxy-s4/help/i9505-slow-wifi-router-t3076105
Hello, im going straight to the point, i use my zenfone 5 (t00j) as a gps device all teh time, i ride a motorcycle all the time, unfortunally on a highway the phone flew out of the holder, got ran over a bunch of times by passing cars, but i noticed it was still alive, the volume buttons would make the bip sound when it reachs maximum volume ( screen wouldnt even light up so that was teh only indication). so i went on ebay and bought a bunch of parts. ok now the issue:
I cant get network signal, but i do have GPS and WIFI working flawlessly, what i wanna know is, does the wifi shares the same antenna? by that i mean that RF cable that connects the charging board to motherboard? is that the antenna for the network? it looks good dont show signs of damage but im at a lost, Sim2 was fisically disconected when i pick the phone up, and the SDcard was gone aswell, those were the main impact areas.
Can it be software bug or hardware? i've changed the sim card slots aswell and a factory reset
SMMI test shows only sim card slots fail and modem bus (wich i think its 3g?) wich would make sense not to work since cant get any signal, everything else pass's
Any help, any info on how that works? sim card slots send the info somewhere, where? what reads those signals?
thanks and if u know of somewhere more apropriate, i know this forum is more of a software related thing, but its active and i may get relevant info around here

respectufully, thats a whole bunch of nothing of an answer, ofc if i buy a new phone it will be solved lol, i have a new phone already, but i want to fix this one, hence my questions above, wanna try and solve it, since its only the network having issues, i might just use it as a dedicated gps/multimedia device since i fixed that much already.
the RF cable, thats the network antenna? what chip reads those signals?
