Signal drops probably internal damage - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi all.
I've dropped my phone quite a few times and it's affected my signal.
The reception on the phone is very weak and drops in certain places where it use to have good signal before. Also sometimes people tell me I sound like a robot over the phone so it's got to be an internal damage.
Iv already changed the speaker/microphone part of the phone but the problem continues, my next geuss is the wifi signal antenna cable.
Any ideas of what may be the may cause?

have you tried some different rom and modem.? if not than try something different. i also faced such issue but after changing rom and specially modem, now me trouble free

assuming he didn't flashed any roms between drops....i think it's antenna related...that antenna is small and looks quite fragile...it's a hardware problem...i suggest going to your local repair shop...

I think it's definitely an internal issue. Signal drops all the way at certain locations when it never use to and some people say I have a robots voice so I have to call them back. Does anyone have any pictures of where the antenna is located in the phone?

Having the same problem here. Dunno exactly when it started but I'm getting lower signal everywhere than I used to get, indoors am having trouble getting any signal at all when it used to be fine.
Tried multiple different ROMs/Radios and a new Sim Card and it's not solved the problem
Also thinking I've just dropped it too many times.

it means is a hardware problem...

the antenae itself its basicly a wire with a connector(atleast the phone one), after the drops, the connection maybe got loose. open the phone up(you lost warranty anyways)and disconnect/ re connect the antenae. if dont work, then repair shop.

How to Increase Reception on Sony Xperia X1

Did anyone tried this out?
http://blog.whitesites.com/How-to-Increase-Reception-on-Sony-Xperia-X1__633958291637656250_blog.htm
Better try to flash an other radio version before doing this to your Xperia.
Edit:
At home i have just 2 bars of reception, but anyway it has a very good connection. Only HSDPA reception could be a little more.
If i am outside my house, i mostly have full reception even with HSDPA.
If you're getting a weak signal from your provider, there's no way to magically make reception better other than the provider giving better coverage.
Being that my Nokia's all have full reception in house and the Xperia loses connection in the same location...

I've changed 5 times already.
The issue is not whether it can be resolved or not, it is how slipshod the SE radio firmware is.
Nokia gets it right 100% of the time, so why can't SE?
The blogger on that link may be onto something (ie hardware related, not firmware) - but I'm not going to do that!
I changed the radio f/w to 1.16 - it's better than before, still not perfect in terms of the number of bars, and I sometimes lose the signal in the local supermarket...
X1 signal quality is poor/below average - but not poor enough to take the phone apart like that, or to actually change it for another.
I have already re-shelled my phone, so I have no fear of this. It is actually very easy to get to that part, but I would think that the rubberized coating would help to prevent corrosion on the copper antenna. Correct me if I am wrong, but wouldn't a cell signal have no problem passing through a millimeter of rubber compound?
I would be more than willing to mod this to get a few more bars, but I don't want to cause damage and not actually have any benefit.
If anyone here has tried it please post your results.
i just did this mod so far there has not been any noticable increases in reception but it seems to be more stable with less drop outs

Wireless and network signals recently very low

Hi all,
Within the past week or so, I've noticed a fairly large drop in the signal strength from both my wireless lan and 3g signals. With the cell signal, it was even dropping to edge sometimes when I was outside in an area which used to give me full bars. Wireless isn't much better, and it seems to be fluctuating between 4/5 signal and 2/5 signal even though I'm close to my router. Again, I used to have full signal in the same location. Nothing really would have changed.
Yesterday I tried flashing Continuum (2.3.4) instead of running the stock 2.2 that I had before. The 3g signal seems to be *slightly* more consistent, although I'm still not at full bars, whereas I always was before.
Is this a common occurrence? Is it my hardware, and can I fix it myself, or do I need to send it in to Rogers? I've only had the phone for about 6 months now. I wonder if it's under warranty still (assuming I flash back the original ROM and bootloader).
If anyone has any suggestions it would be much appreciated. It's odd, but the wifi signal almost gets boosted when I'm trying to use the internet, but not to full bars even when I'm near the router.
Bump. Is this the wrong place to ask this question?
Cheers
My AT&T Captivate has similar issues. Mine started about a month ago. I haven't put any effort into figuring out the root cause.
Yeah, I'd really like to figure out what's up though. Does the hardware just crap out after a few months of use? Thanks samsung!

This trend happened with my HTC Aria as well. I don't believe its anything related to Samsung hardware crapping out.
So, if it's software, what would be consistent across a ROM and kernel flash?
I recently fixed a network error effecting call quality by flashing a new modem. I know our issues are different, but since you did flash new ROM i dont think it could hurt.

Stumbled across this article on Toms Hardware today and felt like it was a good read for this thread.

Unfortunately it's not just my wifi that has issues, but 3g as well.

Have you tried flashing a different modem? The one that came with your current rom may be different than you had before which would account for your weaker signals. Different modems work better in different areas. Try something else and see if it doesn't help, such as JK4 or JL3.
I haven't yet, but I actually had the problem before I flashed the ROM.
Where are you located. I have absolutely ATROCIOUS reception in Atlanta, and ATT says they have some 50 towers down. Your area might be the same. In my basement where I used to have 3 bars consistently, i know have to run around the basement struggling to get one bar to send a text. ATT needs to get their act together or everyone might start switching to Verizon.
In Toronto, Canada. We usually have good reception. It's only recently that I have had issues.
check with other people such as your family and see if they have bad service too, if so call your service provider, there may be an issue on their end. Other than that all I can suggest would be a full reset to factory and a master clear and then restart from there. While that is annoying, it might be worth it to solve the problem.

Losing mobile signal frequently

I have an issue where I lose mobile signal every few minutes. If I use Llama and check the "recent" tab I can see Cell: -1:-1:-1 every 10 mins or so and if I'm using the phone the signal will go to nothing, then within a few seconds go back up. Has anybody else seen this issue? I've done a factory reset and it didn't help. I'm waiting to hear back from Sony support, but they're been pretty useless for me in the past.

I encountered the same problem on my xperia l.
You could try taking the battery out the phone when it is switched on "hard reset" ,then take out the sim card and reboot, then switch off, put sim card back in and reboot, it may take a couple of minutes, it's worked for some, Me included
Another thing You could try is putting Your phone into GSM mode from settings but this means You need to keep changing modes when data roaming

Whilst we appreciate the sentiment please take a look at the forum your posting your advice in. The Xperia Z1 does not have a removable battery and the term 'switched on ''hard reset'' ' makes no sense unless you mean using the red button in place of a battery pull.
Not trying to be rude but its frustrating when your device drops signal and the best advice you get is regarding completely different hardware.
To Chrisduffer: Have you rooted your device/unlocked the bootloader or flashed another ROM? If so perhaps consider an alternative Kernel or a software update via the flashtool if its still using the stock kernel?
same problem. No root / no flash. Stock 4.3. Same issue even before update to 4.3.
Any idea what to do? My signal drops down every day like 5-6 times for about 20-30 seconds with no reason. I'm also not able to connect to 3G (at least phone is not showing 3g sign next to the signal strenght).
Hmm...this is interesting because actually I saw this up and down on mine too but I was able to call and receive calls anyway...so I newer bother if is an issue or not...but I losing the internet connection frequently so what's wrong?
Instresting...mine too...stock 4.2.2 rooted, Lb....but when my signal totally drops I am able to call or text!

Sounds almost like the modem driver is crashing and then restarting. Factory default is what I would try first, unless this is happening in places where you have weak signal or are in an enviroment which would cause weak signal (inside, thick walls, metal, etc.).

Hypothetically.
Had a few issues myself with the same stuff. Try another radio via flash tool. Just deselect everything else and just flash baseband, no wipe. Be careful when flashing stuff.

Yes, alternative radio driver should help, if it's not HW issue.
I will try to give the phone on a warranty check ... hopefully they will be able to tell me what's wrong ..
if not, I'll go your way = flashing different ROM with different radio.

thank you for the answer which rom could i install? now i have the rom for italy (IT) that i found here... but i had this problem also with the completely stock device so could it probably be an hardware issue?
You think you have signal issues?
Almost forgot, I had a phone come in once and it had the same issue, ended up only recognising the sim card every now and again, you could try another sim, or even send it back for repair which is what happened with the phone that was brought to me.

so i'm going to send it to warranty, i hope it is an hardware problem otherwise i'll have to sell it, i can't stay witheout signal as soon as i hold it on my hand
losing data signal
I am having the same issue
Any idea?
Should return the phone?
I sent the phone to the warranty, I have also the results of the tests and they are all passed... So I really don't know how to do... If I find a nexus 5 i'll try to change this xperia for that, I can't stay whiteout signal when my old iPhone 4s receive it very well

bizare wifi behavior

well, my wifi is acting wierd... reception is good and it doesn't disconnect too often, theres just this little anoying thing!
everytime roughly 3-4 days after i flash a new rom my wifi simply refuses to connect to network, and not a specific one, any network at all!
and it stays like this for a couple of hours and then all of a sudden it picks up a a networks and it works fine for a while, untill i happens again...
i've tried restarting and taking out the battery and turning the wifi off for a while, nothing seems to help, he just decides on his own when he is whilling to connect again....
if i flash a brand new rom the problem disapear for a few days but then it comes back... i'm assuming it has to do with some sort of a cache that is filling up with loads of crap and ruining the wifi activity but i tried googling for this and found nothing..
ideas anyone? (btw this happens on all roms: stock, existenz, beanstalker etc...)
its a hardware problem and not so uncommon look here

if you can take it to a customer support and if you cant sell it and again if you cant, then just get along with no wifi/bluetooth/NFC check all of them you should have problem with them too

absolutly not related, my NFC and bluetooth works just fine, i don't need to press hard anywhere...
and my wifi works just fine after a fresh rom install... so it's defenetly a software problem...

to me that sounds like the start of it because mine was the same at the first few days flashing a new rom or something would help alot but then i just found out the only thing that was helping it to get fixed was the heat from the device not the rom, but it doesnt hurt to play around with it a little so go ahead and try some other roms or repairs.
you see good reception for wifi
you try to connect
at the authorizing or connecting you will see only one point of signal and connection would kinda like disappear.
this is how it was for me but at the first days it was random it was connected good and ready, when i would left the phone in stand by after a few minutes it would DC, so i thought its kind of a sleep mode malfunction or something but after a few days almost 1-2 weeks it turned out to be hardware problem like ohers so if you see any symptom like that start looking for service centers.
but i hope it would be a software problem for you, so good luck.
Well, once he connects he stays on for days, no problem there... Just sometikes he refuses to connect... Pressing the nfc button doesnt help...

What Wi-Fi channel is your network on and have you tried 5GHz?
Didn't look into those things, but it happens with all networks except ones without passwords
Sent from my C6903 using Tapatalk
Have you tried deleting wpa_supplicant.conf in data/misc/wifi and reconnecting to the network? (this will delete all saved passwords and settings for known wi-fi networks) also try to disable Auto IP in advanced wi-fi settings
Well the phone is qith my sister now, I got a new z1 so far wifi worka for her, it stoppes for a few hours yestarday but came back, I might try to flash. 310 and see if it works better with it. And the Wapa_sup sounds like a good idea. Btw z1 is also jittering some with wifi, it's a global Sony problem...

temp solution?
Well, it is probably a hardware problem. I have had the same problem, everything looks fine, but you can't connect to any network.
So, searched, reinstalled, etcétera, nothing worked. Untill I read a crazy solution link://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/xperia-zr-wifi-association-rejected/td-p/516275/page/4
and found out that if you put pressure on the back of your pone right at the NFC chip, with a finger or so, the Wifi will come alive again.
Personally I had to hit my pone's back at that exact spot with my finger (for not damaging it with excesive force) a few times, but then suddenly it worked.
So, I am convinced it's a hardware problem. Hope it works for other people too.

Redmi 4x trouble with connection and heat

Hello fellow members. I`ve stumbled upon a trouble with my Redmi 4X. I'd like to ask you if someone had similar problems with his Xiaomi. But first thing first...
I`ve dropped my phone few days ago. Guess what - broken screen :crying:. I did some research and decided to repair it on my own. I ordered orginial replacement kit (LCD + digitizer), watched few videos "how to" and I made it. But.
It seems that now I have some problems with network. Signal strength varies between full and the lowest (on 4G), but it feels like it's always the lowest. The internet is so slow, calling and sending messages is pure luck. Sometimes you can send or call, sometimes it's like out of range. I`ve tried setting "only 3g" setting, but it doesn't help. Factory reset didn't help aswell.
Additionally, the phone is overheating. I think it may be associated with the network problem, since phone can't find himself in range of mobile operator.
I called mobile operator and they didn't do anything, everything seems to be as before.
The phone is updated to the most recent OS (Global). I don`t have any necessary or strange apps, nor root or custom rom.
Before the change of LCD everything was running smoothly.
So, did any of you guys had some similar troubles with his/hers xiaomi? Could I broke something during the replacement? I think not, I was extremely careful, assembled everything as it should be but still..
Hope you guys could figure something out, since I`m really out of my mind what is wrong now.
Thanks!

Hi, the poor reception and overheating symptoms are typical of bad antenna or its connection, which were probably damaged during the impact. Without an antenna, RF transmitter has nowhere to dissipate its energy, hence internal overheating.
Please examine the PCB-antenna pairs of contacts on both sides of the connection. Good luck...
:highfive:
Try switching between preferred network 4G/3G/2G and see if you face the same issue.
you can also try using different network carrier sim into your device and your sim cars in other device and see if this issue persist
if issue persist try reconnecting antenna cable.
