[Q] My data signal is weak - Verizon Samsung Galaxy S III

I was wondering if I should update the radio, or the modem as they call it on the s3. If anyone has anything to say about this problem please get back to me. Thanks

Which rom are you using? 4.2.2 have always "shown" lower signal than i was actually getting, but i always had good signal and never dropped calls.

I'm running jellybam 7.5 now. I was running liquid v 2.2, which had a weak signa, is why I flashed jellybam. Thanks for the reply

I flashed the newest modem recently and I noticed more signal in my basement (where it was usually very bad) but curiously less out and about in the city (where it was usually spectacular)

I just flashed the latest modem, and my signal just grew 3 plus bars. Awesome. Thanks

[Q] WiFi sucks on CM7

Okay so on CM7 my WiFi signal is just way weaker than it should be. I'm in the room right next to my router, and I have like half of a WiFi signal...On every Sense ROM I've tried (and the stock ROM), my WiFi works perfectly fine, yet on CM7 it's complete garbage...Does anybody know how I might solve this problem? Somebody suggested I try a new radio. I had been using stock, but I flashed the Telus radio and it was exactly the same. Also, why doesn't CM7 have an option to use like Advanced WiFi or w/e (where it works better but uses more battery, it's an option in the stock ROM)?
I'm on CM7 also but my WiFi is the same on this as it was on CoreDroid and stock ROM. I had the Atrix prior to the Inspire and will say the WiFi on that phone was annoying. I could stand right near my router and I'd have 1 bar of WiFi like really?
My Wifi was great on coredroid and inspiredsaga, buy not cm7 for some reason

That's strange. Does it run slower or just show less signal? If it runs at little to no noticeable difference is it a big deal?
I'm not sure because I don't really browse the web on my phone through wifi, I usually only download Apps and whatnot.
I'm not sure if it's slower, but I lose connection sometimes. I'll be downloading something and it will say "connectivity lost. rety?"

Are you checking signal strength in decibels or just bars? Decibels is the only way to make a fair comparison. Some ROMs may have a different bar/decibel ratio. 4 bars on one ROM might be 3 bars on another for the same given signal strength.
FWIW a couple of weeks ago I was curious if different ROMs affected signal strength. I tried rooted stock, CoreDroid, TPC, CM7 and Ultimate Droid and noticed no change in decibel signal strength. Wifi Analyzer and Network Signal are two such apps that will show decibels. Be sure to measure signal strengths in the EXACT same spot and take an average of signal strength (as they will vary a few dB normally).
One thing I noticed since switching to CM7 is that my signal strength is more accurate. My laptop shows 3-4 bars when I have it right next to my phone, and on the stock Sense ROM I was showing max signal. Now on CM7, I get 3-4 bars of Wi-Fi signal strength, so I think it's all a matter of how it measures. If you are seeing serious performance issues, then that's a different matter.
FWIW, I have not seen any Wi-Fi performance issues between CM7 and stock ROM.
I had the same issue with CM7.
At one end of my house, one or zero wifi bars with CM7. Kept flip-flopping between wifi and 3G, disrupting use.
With stock ROM or TPC Stock Optimized at the same location, phone gets one or two wifi bars and I can surf without the phone flip-flopping between wifi and 3G.

That is just a slight radio mismatch issue between CM7 and whatever radio you're using (it sounds like you're using the stock radio). I had the same thing happen to me using CM7 with the stock radio. This radio is fine for a lot of ROMs, and it gets good signal strength, and phone calls were no problem, but using CM7 in 1-2 bar wifi strength areas it would flip between wifi and cell data way more than it needed to. Flashing to radio 12.48.60.23U_26.08.04.07_M3 and flashing the RIL file HTC-RIL_2.2.1003G fixed this problem for me. Now the phone stays locked onto weaker wifi signals much better.
I read somewhere on this forum yesterday that one of the new nightlies for CM7 is going to have a different RIL in it; maybe it will address problems like this.
same here
i was having issues with my wifi and signal bars w/cm7 also, so i just switched to ace.

Signal Drops - More Frequent Each Day

Hi Everyone,
I'm experiencing serious signal drops with the HTC One X LTE. It used to happen once a week, but now it happens like every 30mins, which is drivint me nuts. Can someone let me know if it is a hardware issue or a software issue.
I'm currently using the CleanRom 4.1. I flashed the phone right away, so I'm unsure how the phone is like on stock rom. I'm curently with Rogers Canada.
Force your phone to use only 3g . I have had this issue... Click on my profile and read my previous post.

I'm already only using 3G. I turned off LTE because it was draining my battery like mad. With only 3G i'm still getting terrible signal drops
Its happening to me too. On stock and on Cleanrom. Starting to piss me off. Even going into airplane mode sometimes freezes
Mine was dropping a fair bit on stock 1.77 and moreso on AOKP and CM9 based ROMS.
I found updating to Telstra 1.89 firmwares has fixed nearly all my connection issues on 3g/lte and wifi.
Try going into recovery, and clearing cache & Dalvik, then reboot.
Simple fix (and certainly won't hurt), and might not fix your issue. But its cleared up signal drops the few times I've had them.
I really think it's more network related. I saw a lot if this on 3G before getting the HOX. Seems to have cleared up in my area.

Get your carrier to give you another SIM. Fixed my issues and cost me nothing. Cause the iPhone micro Sims are too thin and don't sit right in your slot. The new still cards are thicker

I actually had this issue on cleanrom 4.1 only so I flashed back to cleanrom 3.1 and I haven't had a single drop since. Lemme know if this helps.

[Q] Stable Tmobile radios for a JB ROM?

Hey Guys,
Just wanted to know if anyone had any success flashing some Tmobile radios on their Skyrocket with a Jellybean ROM?
I am currently running AOKP JB Rom, and I have a Tmobile signal, I can make calls and text, but something seems to be blocking my data. APN settings show T-Mobile US, so I know there is a connection.
My current Baseband is: T989UVLH1 <----Is that the problem?
Thanks in advance.
I'm running R4INS AOKP Oct 24 build. Unfortunately I can't seem to get hspa working correctly no matter what radio I flash. I'm going to try a few other ones and report back. I get edge without a problem, but it has issues with H+. I get widely fluctuating strength and terrible down speeds (5kbps). The upload speed is better (300kbps) but not what I should be seeing in my area.

[Q] Little to no signal and no mobile data access

Well I'm on the latest CM nightly (CM 10.1 -20130312) and I just came from CM 10. I tried CM 10.1 before but I had little to no signal and I've decided to give the latest nightly a chance and well, I still have the same problems as before. I flashed the 3.18 radio on it and it literally made NO difference at all. I hate the AT&T variant of the phone. On the CM 10 version I didn't have this problem but there were times that I'd go half an hour to a full hour without getting any texts and then they'll all come in at once (and I know its no coincidence because some of those messages contain people wondering why I haven't replied yet). So can anyone help me with this problem please?? I really like CM 10.1 but not having any mobile data and an even worse signal is a REAL deal breaker for me.
I was having the same issue until I went into settings and changed it to GSM/WCDMA.

I used to be tech support for att. Obvious question: has this happen before? Now to put my xda hat on. Did you change APN settings? Is this the only rom you flashes? Also call att (611) and have them cancel registration. This basically kicks you off the network and bring you back on. Sim cards are not the issue as the are unable to determine signal strength. Hope you get it fixed.

I think it has something to do with the 3.18 radio. I never had problems until flashing it. I have tried multiple roms. Sense based and aosp. It happens on both although it seems to be worse on aosp. I went out of state and lost signal completely while running the latest Chameleon. I went into settings and as soon as I stopped it from searching for LTE it went to full signal. Maybe a tower upgrade issue? 3.18 radio issue? I guess it's something for devs to look into. I know not all towers are the same. 3.18 maybe conflicting with the area he is in. Somebody will get it figured out lol.

That's just weird. I flashed 3.18, and still get the same coverage (4-5 bars, 6mbps data). I don't see how it can effect you. The device is dual HSPA+/LTE. So if the device cannot find LTE, it will always back (circuit switch fall back). Even when I went to an LTE area (Nashville, TN), it still work perfectly. Could be something up with the physical radio inside of the phone. The LTE towers are suppose to be backwards compatible, but we know how companies can be. If your device is working in one area, and not the other, then it is a tower issue. Even though AT&T may find that their towers are ok, it is a tower issue, and there is no doubt around that. Now if it just gives you random coverage, no matter where you are, then it is the phone itself.
Having the same issue on CM. Just tried changing to WCDMA and my signal doubled. That is weird but thanks you guys.

[Q] OTA Causing Data Issues

I was stock unrooted and i got the ota. now my data handoffs are weird. in my house were i get 3 bars of 4g lte (-100ish dbm) i now have 2 bars of 3g and it switches between 3g and 4g. it didn't do this before. i then odined back and installed the ota again and same issue. Any suggestions?
New radios won't be the same for everyone. The new one may hold 4g for somebody else, but knock you down to 3g all the time. It all depends on your location. I say give it a few days to see how it is, then go back to the olds radios (MB1).

Interestingly enough, every time I receive an OTA, I factory reset for a fresh experience ( placebo or not, it feels like dirty flashing and never seems to run as quick or as smooth). However, every time I did so on MD3, and I tried 3 times, after the reset my data would barely work. Had a signal, showed 4G, just never loaded or indicated data transfer most of the time I tried to do anything.
I wanted the update obviously, so I ended up Odin-ing back and flashing the recovery-based version. Still using LK3 and its faster and more responsive than MB1 ever has been for me. Just food for thought.
Edit: LK3 modem vs MB1 modem
