very weak signal - Galaxy S III Q&A, Help & Troubleshooting

I purchased a galaxy s3 international version about a month ago. The phone was working fine for about a month until yesterday, my phone is getting very little or no signal at all. also, when i connect my phone to my car, the phone will start calling itself. i performed a factory reset and the bluetooth problem was gone, but the phone is still getting very little to no signal. wifi is working fine. i called Rogers, my service provider. all they ask me to do was to buy a new sim card or remove the battery from the phone and wait. none of those helped... :crying: i'm kind of desperate here as i can't figure out what went wrong with it... my phone is not rooted or anything... if someone can help me out, i would really really appreciate it. :crying::crying:

Unless you are willing to start flashing modems to your phone there isn't much we can do for you.
Best bet is to keep pestering your carrier if you don't wanna root and modify your phone.

thx for the quick reply. So rooting my phone and flash a new rom is the only solution? :crying: is it possible it's hardware problem?

Not a Rom, not before trying modems anyway.
It may be hardware related, you should keep pestering your carrier for a replacement.
If it world fine before then chances are its a hardware issue or the cell tower near you is down.

i just found out in my mobile network setting under access point names, there's LTE ththering and Rogers LTE, could this be the problem? cus my phone doesn't have LTE maybe that's why? sorry, i'm not very good at phone stuff, it's just my random guess...

Is your phone International I9300 ????
Or are you possibly and no offense meant in the wrong forum ??##

Did you try with a SIM of other network? This may at least point out that either it is network problem or hardware problem.

I don't have another micro SIM... I tried flashing different modem and firmware. But none of them works... the phone is connected to the network, just the signal is extremely low all of a sudden... I had an software update 3 days ago, maybe that's why?

I don't know if you tried to pull out the simcard and clean the contacts. This was a common issue on the HTC Desire HD and this little fix worked fine.

Is the phone new? Has it ever worked for you? Have you considered the fact that it could be network locked(SIM locked)?
My phone ALWAYS shows "Not registered on Network" when I'm at home, that's because signal is terrible since I updated to JB (modem related).
Have you tried different SIMs from different networks? Have you tried your current SIM in a different phone?
[the phone is from 29 june..always worked bit one day data stopped working.. i got a HTC sensation and the SIM works fine in that phone/SIZE]

Ok,
so here comes the question my girlfriend always asks me :laugh:
"What did you do between it working, and it no longer working?"
You say data doesn't work, does that mean you can make phone calls?
I didnt do anything it just stopped working and i cant do phone calls...its like using an iPod.. maybe someone blocked my imei?could it be possible?

Yes, it's entirely possible, but you'll need to check with your provider. There is no way of checking from the device itself if the IMEI has been blocked.
Did you buy the phone new?
You could, potentially, be extremely unlucky and someone blocked the wrong IMEI code when attempting to block their own.
Ye it was new..there is no way to make it work then?

Well, if it really has been blocked, you should get in touch with your provider, and potentially have to go through some lengthy process of proving to them you legitimately own the device and didn't block it yourself. It's unlikely though, as I've never heard of a device being removed from the block list before.
Your other option is to leave the country, it will work in another country
Failing that, return it to Samsung telling them it just stopping working, you did nothing, and insist they replace it.
Probably wrong Kernel, happened often to me on my old sensation

[Q] Question

So i bought a samsung galaxy note off a guy on craigslist about 3-4 weeks ago and today i noticed i didnt recieve any calls or texts from anyone, so i checked my phone and could get a signal at all, so i reset the phone to factory using kies and now it says, Phone Not Allowed MM#6 and i cant connect to any network
someone please help and tell me what i can possibly do to solve this issue
I did a little research and it could be a few things... Either you've gave the carrier the wrong IME number or the phone was reported lost or stolen by the original customer... I would call the carrier the phone is for and ask them. Also if the original owner hasn't paid his phone bill the carrier can lock the ime from being used... I've heard a lot of people buying phones on Craigslist like that...

so it's an AT&T note and you're using it on Tmobile right? have you tried an AT&T sim? If you don't have one available to you, I think you can go into an AT&T store and ask them if they can do a quick check for you. Be sweet, apologetic for using their time, maybe send your gf in to flirt with them a little they'll more than likely give you a hand.

What modem is showing in the phone ? (needs blaze modem for TMO, if it's an ATT device)
And are your APN settings correct ? (needs the TMO apn's)
Two nails in the coffin for service if not correct.....

Unlock is permanent. Getting t- mobile to work on the at&t version is hit-or-miss.

Help fix 4G :(

Im going to explain this problem in a depth as i can.
I am s-off'd via jtagged, rooted and have twp recovery. I am on newest radio running NOS M7 v2.0.3
I can only connect to 3G for some reason with it reading eHRPD.
i do not know if it was reading this before i started the process of rooting since i never turn the phone completely on once i got it back.
So after some reading and advice i downloaded LTE on off to force 4G
It worked but at the cost of losing my mobile network causing me to not be able to make calls or send out text but i have 4G i can get on the internet.
Atm i am plagued with having 3G and service or using 4G w/o service... and this is a problem.
Also while on 4G it reads RSRP if that helps.
Idk if this is a hardware problem from me getting my device jtagged (which would suck since that means im stuck with it) or if it can be fixed.
Any suggestions would be highly appreciated since im getting annoyed

I had the same problem when I got my phone back. Took it back to Verizon and got a new phone. I tried everything and nothing worked. It is like something happened to the radio. Tried to flash a new one nothing. Still haven't heard back from mtv on trying to get a refund.

Sigh thats something i wanna avoid so Ill just have to stay stuck until moonshine comes out. I really like sense 5 and I don't wanna go back to 4+... Then I'll get a replacement I guess.
As far as RUU to stock and seeing if I was on LTE I already did all that. I was almost looking into build.props but I assumed that wouldnt work either. So guess I'm just stuck on 3G unless it randomly wanna come back which I doubt unless somebody comes up with a solution besides just getting a replacement.

Correct they are free, but the guy I tend to see at the Verizon store always seems to launch that hboot screen everytime I go in there. He did when I had the SIM card swapped earlier in the year as it would disconnect from my network several times a day. So I just want to be on the safe side.
I had my SIM card replaced twice on my resound and both times went to the store without relocking the bootloader or anything. Didn't have any issues. They programmed the new card and I was on my merry way. Maybe call em first and without giving any of ur account information ask if u can get a new SIM card if uv rooted ur phone. It would suck to go thru that process if it's not necessary but I can certainly understand the better safe than sorry approach. The phone call would definitely be worth the time though imo.

I think it was resolved after I flashed my radio and then I went back to stock just in case I have any more issues in the next week. As if I do I will go back to the Verizon store and swap out my phone. But I'd rather be S-ON in case that happens and be that way for a bit. Plus I wanted to test the S-ON for future purposes of in case I needed to get back there I knew how to.

[Q] No 4G LTE after flashing Cyanogenmod 10.1

After flashing Cyanogenmod 10.1 I have only been able to connect to 3G and cannot connect to 4G LTE. Does anyone know how to get LTE to work on Cm10.1?
Try doing a full wipe. Data/cache/dalvik, reflash CM.
Sent from my SCH-I605 using xda app-developers app
Also be sure you have LTE enabled in your network settings.
Were you ever able to regain LTE? This has happened to me as well. I've tried flashing back to stock, changing settings using *#*#4636#*#*, and a couple of others. Still nothing. Hate the idea of relying on 3G.

This happened to me. I ended up getting a new sim card and that fixed the problem.
Try putting your Sim card in someone else's phone that has LTE. If they only get 3G, it's your card. Of they still get 4G, it's something else with your phone causing the problem.

Something similar is happening to me. I'm on Carbonrom 1.8. 4g just stopped working. Have been reading around trying to get fixes. Got a new SIM card from Verizon and it still didn't fix it.
In my phone status it says I'm on CDMA - eHRPD:14, I believe this indicates I truly am on 3g. If it were 13 it'd be 4g. I think I have that right. I haven't come across much that's helpful although it seems this isn't that rare of an issue. Trying to fix as much of it as I can on my own. I've yet to revert back to stock. Have tried going to Beanstown, that did more harm than good (broke sms and didn't go to 4g).

Beans ROM is basically stock if you went to that and still didn't have 4G then there is something wrong with your phone. Try the dialer fix (Dialing the number posted above) and if that doesn't work I would start thinking about a warranty replacement.

Most likely would have happened anyways. Rooting and ROMing don't touch the modems that control your cell signal.

I haven't come across much that's helpful although it seems this isn't that rare of an issue. Trying to fix as much of it as I can on my own. I've yet to revert back to stock. Have tried going to Beanstown, that did more harm than good (broke sms and didn't go to 4g).

Odin back to stock. It usually will solve strange issues like this.

Having the same issue, mine came after i *228 my phone. It went through updating roaming and since then its stuck on 3g. Downloaded the Odin file going to try in the morning.
Ps. Attempted to insert my wife's sim into the phone to see if my sim was just bad but even with hers I was only getting 3g. Tried to flash the latest radio in twrp but didn't fix it either

Noob input
Just rooted my Razr Maxx (had a rooted Droid X). Flashed CM 10.1, while on CM NO 4g, go back to stock ROM and DO have 4g. I've switched back and forth several times and remains the same.
Sounds like a CM problem, but hey, I'm no expert, pretty noob.

NEVER *228 a 4g Verizon phone. It will and most likely burned up your sim card. *228 is not compatible with 4g devices.

Lesson learned. Did it on my galaxy nexus all the time without issue.

This happened to me. I ended up getting a new sim card and that fixed the problem.
Try putting your Sim card in someone else's phone that has LTE. If they only get 3G, it's your card. Of they still get 4G, it's something else with your phone causing the problem.

Same thing happened to me. Verizon changed it for free.

This alone did not work...however, I got a new sim card after doing this and I'm back on 4g. Got fixed a bit ago but was unable to post. Thanks for the help. No 4g was bugging me, but unfortunately it means I'm stock for the time being

[Q] Weird problem

Okay guys I have this problem with my Atrix 4G. It's usually on NottachTrix 2.0.0 or 1.9.0 since 2.3.0 was giving me weird errors. The problems I am having are that I have a strong signal of 4-5 bars and then either after an idle or just by watching it sometimes the signal degrades and eventually it's greyed out with a little x over it and it stays like that indefinitely. I've tried turning the wifi on and off, the GPS on and off, I've done a factory reset. I've repeatedly flashed the radios. 30, 36, 37, and the sbf of OLY_ATT_01.97.00R. I've done it with the sim in and out, with the sd in and out fixed permissions. " And I still have the issue of the signal either being completely off, or just degrading. I'm using this on T-Mobile but when I search for providers all it shows is AT&T and when I go to About Phone -> Status I consistently have between 90-120dBm under signal. What am I doing/not doing right?

i'm not knowledgeable about this issue, but based off of what you said, you're using ATT radios on a T Mobile network. perhaps a T Mobile radio would work? if i'm wrong with this statement, then i am and i'll admit it, but thats what i would try.

Im not sure that's how it works since the radio wasn't designed for this phone. Oh and it was working before and kinda worms if I reboot the phone but it still degrades

I always flash through CWM except for the 00R radio. And I just tried the other radios on the internet from the internationals to the UK to all US radios, still no luck at all. Is this a SIM issue or is my phone SOL?

i think i need to back track here and ask if you unlocked it so it is capable of running on different carriers. next would be did you set up the correct service settings like the vpn and stuff. and have you tried flashing, via fastboot or cwm, any t mobile radios?

Does this phone even have T-Mobile radios? I've flashed Via CWM, I am bootloader unlocked and SIM unlocked I have no clue what a VPN is but the APN comes with the phone I think.

lol apn is what i meant, not vpn, my bad. but yes, do you have the T Mobile apn info set up so it should work? and this phone was never made available for T Mobile, so it doesn't have any T Mobile radios. you would have to look for T Mobile radios to do what i was talking about trying out

What T-Mobile radios do I look for? Isn't each radio made specifically for each phone? And When I catch signal it does work.

ok its hardware issue. below is a paragraph about a different device that might point you in the right direction
"Did u follow the guide on XDA forums? They have the original guide for unlocking AWS bandwidth for ATT note 2 so that it could work on T-Mobile 4G.
If you flashed it correctly your phone should virtually pick up tmobile 4g any where you go.
Unless you live in a rural area that is."
it would be a hardware issue that should be able to be fixed using whatever was used in the case above. it may be about the note 2, but they did ask about other devices, so i would think it might work

From What I was reading, that method was for phones that have T-Mobile Variants that just have the 1700 Band blocked. Tmobile reps say it's probably a SIM issue which I'm hoping it is so I don't find out I have to buy a new atrix. But if its Software I'd love to be able to fix it now and get it over with.

I quite had somewhat similar problem but enabling 'use 2g only' I was able to avoid the loss of signal
