Does anyone else find the signal bad on their GS2? I have had a lot of Android phones and this one constantly goes through G, 3G, H...although when on 3G i receive nothing data wise until i goes back to G or H.
I have had the following Android phones while living in the same home.
HTC Tattoo. Always H 3-4bars.
HTC Desire. G only (RAREST H in front of my pc) however i think it was faulty looking back.
ZTE Blade. 3-4 bars H.
Moto Defy. 3-4 bars H.
HTC HD2. 1-2 bars H.
Xperia X10i. 3-4 bars H.
HTC Sensation. 3-4 bars H.
Now my SGS2... So as you can see signal is pretty good in my area depending on the device. Is there anything i can do? Do any of you experience weaker data than previous devices? I don't really want to return it!
The phone automatically drops to 3G to save battery when data is not being used, if you have having problems try a different modem, start from the newest and work backwards till you find one that works well for you, newest isn't always best, as modems are region specific.

Yes I just discovered a modem thread. All in CWM format which is great!
Think kg2 works well as that's what tmobile sent the phone with. (2.3.3)
Just trying the 3uk modified one... Seems to work well too!
If anyone else uses t mobile uk and feels like suggesting one feel free!

I would try KH3 modem for starters .

Thanks will give that a go. Signal has been ok except for at work. Usually 2 bars H or 1 at the worst. Today dropping to G a lot. Will keep testing. Thanks for the replies.

i noticed 2 days ago my i777 showed h for a sec then 3g and was gone i tryed to google for this and found no info
this morning i wake up power on my cell and sit it on the table next to me while online and notice again its showing 3g h then 3g holding the 3g i browse and it goes from h back to 3g i did a speed test to verify this and i get 4.1mb on 1st try
so is tmobile now rolling out for a new band cause i thought tmobile could not get anything bu e edge for our i777
if any one needs info let me know
however i have noticed that if i pick up the phone is almost always goes back to e edge seems like it must have a full bars of e edge before it snaps over to h then 3g so i really want to know whats going on and if so how to maybe keep the 3g and h cause it really seems sensative when i pick it up and hold it i get almost full e edge and the 3g h goes away
im using aokp
set rom controls to hspda andhuspa or whatever it is
sitting on 3g for about 15 mins now pretty excited ths would have been good a week ago while trying to download google drive and do some mapquesting that got me lost for 40 mins due to slow internet while driving
i was shocked so i took a video and a pic of the phone
i know this may be due just to the area i live in but still this is cool as far as i knew only the galaxy note could have its modem changed software to get on tmobile 3g i thought us i777 users were destined to get e forever i know tmobile was going to get a band back in oct last year and all this junk with att and then somthing about rogers getting it idk whats what i know tmobile is upgrading the whole reason they changed the modem in thier t989 and 3 weeks ago my net cut off totally for the day had major issues and tmobile was no help so i wonder if this is a indicator that before long we all will have 3g ? on i777 if so yet another reason to get my i777
T-Mobile is rolling out HSPA on the 1900MHz (PCS) band in some markets.

sounds great
but.... i can only get 3g or h
when the phone is setting on the coffe table near window undisturbed lol
i go stand out side and still no 3g or h even after 5 min
i sit it on the curb lol and i get 3g but sometimes back to e
and in side the coffe table wins with 3g and h consistantly taking up to 5 mins to switch back from edge once sit down tho ...
lol thanks alot tmobile the i777 modem and antenna are not weak are they
aokp
siyah kernal
nothing modded from stock or changed tho not using dualboot either

can u suggest a better more battery draining modem to try i do not care of batt life if it will be good enough to stop losing the 3g h when i pick it up off the table or direct me to the post with the locator i cant find it again was a link to g maps with search for areas and comments on best modems for areas
OR DO YOU THINK MAYBE IT IS WHAT IT IS I NEED TO WAIT FOR BETTER SERVICE BEFORE THINKING I CAN MAKE IT BETTER ON MY SIDE MAYBE ITS JUST TMOBILES SIDE AND THEY SOMHOW NEED TO REFINE THIER CATCHING OR WHATEVER YOU WOULD CALL IT
Usually cell carriers don't light up a new service on every tower in an area simultaneously while they're still rolling it out. That's reserved for the big public unveiling. Eventually the gaps will fill in. It's also possible your local geography is making 1900mhz reception worse than 850/900, but again, it's more likely it's not on every tower around you yet.

That's what HSPA is (idles in UMTS, aka 3G).
As stated, coverage is spotty because it's just being rolled out. It will become stronger over time. I suppose you could find a way to lock it to Edge if you want (easily accomplished on AOSP roms).
As for modems, it'll drain less if locked to Edge since your HSPA signal strength isn't good. You'll have to look at the map in the modem thread for suggestions. It's mostly different for everyone.
Folks,
I went to a Telstra shop (Australian 4G network provider) and was testing the 4G capabilities of the device. Having a HTC one XL to compare and an SII 4G, I noticed that it took a lot longer to connect to 4G. When it did connect we could only run speed test once on 4G and then it would not reconnect to 4G, always sitting on 3G. It was not a reception issue as the other 2 devices next to it were working fine. We placed the phone in flight mode, turned off data, 're enabled data, etc and nothing would get it back on 4G. There was only one SIII to check or compare so I am curious if others have the same issue? I can confirm it was running 4.1.1. I wonder if other i9035 users experience the same thing or its just a Telstra / one off device issue?

Not sure abt telstra but my virgin S3 4G always stick to 4G whenever available

They are meant to automatically connect back and forth from 4g to 3g where evere there is the coverage. There might be a setting, I am using Vodafone at the moment as my number has been with vodafone for ages, and I am not that worried about 4g untill the coverage becomes much larger, by then Vodafone is going to jump in the game anyway Early 2013, so will see how it goes, might jump into telstra or optus, I am pre-paid as I love to have the choice and no lock-in contractss
I'm on Telstra in Melbourne and can confirm the data speeds are fantastic and don't have any trouble getting on the 4G network. Infact, when in a 4G coverage zone it is always on 4G, doesn't 'step-down' to 3G or HSDPA+, Just sits on 4G ready and waiting.
I got 2.8MB/s down and 2.4MB/s up from my work on Collins Street.
So couldn't be happier.
And once I rooted and removed all the bloatware, runs perfectly! Really couldn't be happier.:good:
One thing I noticed is this modem is better than the standard S3. I get better 3g signal now inside my place than before.
At Sydney airport.....first taste of 4g. Wow! It's fast.
I have done a few speed tests of my data and it has always been good. The other morning I was at Skippers airport on the way to work and I thought I would give my speed a test.. 48mbps, I was shocked (in a good way..), I did not know those speeds were possible.. I need a speed app with a higher speedo as mine stops at 20mbps.. So old school now with 4g around..
Max I got in the city was 50mbps (bear in mind I only did two tests). My speed at home using my Optus ADSL connection (with Optus) my speed was under 2mbps.. Crazy difference..
Attached is a pic of my speed tests, the last two are the really cool ones.. I will have to test the speeds at Skippers when in the airport again next week.

Was that a Telstra or Optus S3 4G?

Moving to Q&A
I live in Portland, Oregon. I am a noob on this site, but I seem to be having issues with signal. For some reason, my Galaxy S2 on Straight Talk will drop from H+ to 3G in the middle of downtown! I am running the mod for 4.2.1 on my phone. Does anyone know a way to either boost the signal strength or get better overall signal?
It should drop to 3g when no data is being used. Back to H+ when you're using it again. That what you're saying?

even when I'm trying to upload, it likes to cut out of the h plus signal go back to 3g. even when I try to do a speed test, it will cut out to 3G and not it is any results on the speed test.
Hi all! First post in the Alpha section... Got my Alpha the other day. And i love all about it. But there is one thing thats gets me wondering. It's the reception. All my previous phones got good reception at home.. i get 1-2 bars. So my question is. Does anybody experience this issue? I have experienced SMS delays and chipped calls.
Location : Sweden
Provider : Telenor
Look at actual signal strength in dBm. Bars are arbitrary and vary from phone to phone.

Yeah, i have.. it's lite around -110 .. My Z2 had around -70 to -80 in the same region..

It could just be a faulty device... I'll try replacing my sim first. If that's the issue.
If that's not working. I'll have it replaced.
Edit: Had my sim replaced. Still experiencing bad reception. It goes as low as -105dbm... where my z2 had around -70 (same network, same location)... that's bad. Any ideas what I can do to solve this?
Yeah keep me updated - my Alpha also seems to have noticeably weaker reception than my iPhone on 4G (800mhz band).
Hoping its a modem firmware/software power output thing and not a hardware thing.
Same here, looks like the reception is 1-2 bars worse than other phones.
But I have no experience of delayed SMS or failed calls and the speeds on internet is very good.

Signal problems
Hi, I'm on my second Alpha and first sim, I have an alternative sim yet to try but have chated on Twitter with another user who found no improvement with a new sim and changed phones completely. I'm with three. My signal goes completely when I'm sitting with other three users whose phones work fine. I think it's a phone fault and am considering sending it back now.
Hi guys,
I noticed something interesting with my Alpha:
As you, I have a poor signal strength. But when calling someone then the signal bar jump to full force instantly!
Could it be a link with BIG little technology?

Well, for those who have the same problem, I deactivated the 4G. Then the signal strength is better. I made the test: 2 bars with 4G enabled in network settings, full signal when 3G only.
As a possible future Alpha owner, question.
Are you on a USA Network with the Qualcomm Alpha ?
Or in Europe on Exynos Octacore ?

I am using a european Exynos one
The alpha is my second LTE able phone. Both showed a completely different signal bar reading when using LTE (and checking in lecture, how Signal strength is meassured for GPRS/EDGE/UMTS/LTE it shows, that LTE uses a completely revised scheme to calculate the signal strength)
I haven't made any speed measurements yet, but my feeling is:
(4G) With LTE, even without any highlighted bar i can use internet, webpages load fast, other lookups work.
(3G,3.5G) With H/H+ , and at least 1 bar highlighted, internet works
(2.5G) Edge and at least 1 to two bars, internet is available... three bars are better for it to be worthwhile
(2G) G only - forget it. I'll need 4 bars to surf the web, and i must wait. Chat works if i'm lucky and got at least 1-2 bars.
Apart from that: the signal bars in 2G and 3G show the strength of the signal - but aren't any measure of the quality of the signal. They show anything that sends on the frequency/timeslot of the 2G/3G signal you're receiving. If you've got heavy interferences, you'll get full bars but it all is static.
(Like - in a disco, you've got loud music, and people speaking very loudly to you - that would be full bars, but not the best place to speak to each other....)
I don't understand exactly what the value used by 4G exactly means, but it sounds like it only represents the LTE cell you do want to receive - so it should be more accurate and cutting out the noise somehow
I think you're right ! This is my feeling too. In 4G calls are always perfect for me even with one bar.
In settings we can also have a more accurate highlight on to the signal strength in Db.
Guys this alpha is full of mysteriousness !
I think samsung did it ON purpose.. ! Save battery??
I have weaker signal too.. on iphone 5 is full and i had on my former Honor 6 full as hell..
But I dont konw IF samsung wants to save power by this .. I think it has no much influence as iphone 5 nor Honor 6 had full signal and battery never got down fast.. when I had Honor 6 100% at night it was 98 % in morning..
Another thing with aplha ,when i leave phone in sleep half hour or longer , th emobile network stops and wont come up...
I have to restart phone or turn airplane on ad off.. then H+ or 4G appears..
I have the issue with mobile data too, it seems to also do it when it has been on WiFi for a while and you change to mobile data.
no service
Hey guys,
I have a very bad reception with my Samsung Galaxy Alpha when i'm in the subway in Paris. To be honnest I have no service, no sms, no calls, and for sure no internet...
I can see people using their smartphones inside the subway without problems.
I had an iPhone 4 during 3 years, and didn't have any problem with it when I was in the subway.
I'm using the same phone carrier "Bouygues Telecom"
So what's wrong with this Galaxy Alpha ?

it disables data carrier APN and it won't turn it auto i went it that settings and had to tap that circle manually to get green .. think it is bug .. need sorting out updating software..

looks lik eit might be a software problem .. we need to contact samsung bout it or complain on their site.. but guys all of us we must complain not just one person cos they wont sort it out..
Hey people,
I'm also having connection issues:
When I boot the phone it's working is at should: Switching between 4G/3G/EDGE etc. After a while the connection sort of times out. I can only make emergency calls. It works flawlessly for up to a day, or it can only work for like 5 minutes.
Rebooting the device fixes this temporarily. My service provider (Hi in NL) has already sent me a new simcard which doesn't help. They are now saying I should send it over for repair.
Btw: When i leave it in CDMA only, the problem takes much longer to arise (like a couple of days).
I can see that people who have posted in this thread are having the same issues. I'm wondering if this is firmware or hardware related, as I want avoid sending over my phone. If it IS a firmware bug, sending it over for repair obviously isn't going to fix this.
I have sent an e-mail to Samsung BeNeLux. Like Simona Simmy says, we should all write to Samsung
