Hey folks, I noticed that on my At&t samsung focus that the connection often doesn't switch down to edge when 3G is at no bars(tested-no data). And I know that areas I visit often have edge coverage because i can turn off 3G manually and get good reception... but any insights/solutions as to why the focus doesn't automatically switch bands/connections? radio bug?
edit: I did do the hsupa/dpa release hack via diagnosis console.
This also bugged me. In my experience this is not limited to the Focus. I encountered the same issue with the Tilt 2. It took probably a complete loss of 3G signal for the phone to switch to Edge and then even though the Edge signal had 2 bars, as soon as it got just a trace of 3G signal it went right back. Fortunately with the Tilt 2 I am able to turn off 3G and the phone stays in Edge all day long in areas where 3G os crappy. I wasn't able to do that with the Focus.

I'm having these problems as well and I also did the hack. Since then I keep getting cannot connect messages in IE. It was so frustrating that I undid the hack(?) and this happens all the time. Can someone give me the settings to make sure I restored the original settings.
i own a samsung galaxy s2 ordered from uk,
everything working fine except for this serious issue that i have been trying to resolve till now.
i have a monthly internet subscription from my carrier and it always been working fine on my iphone ( i mean here connecting through the 3g network ). but in the S2 .. i have to use Edge to be able to access the internet ( the mobile network mode must be set to GSM only ). whenever i switch the network mode to GSM\WCDMA auto , the 3g icon appears but when it tries to connect to internet, the phone automatically switch to Flight mode and i loose the network signal. and this happens all the time. till now i am only able to connect to the internet by switching the mobile network mode to GSM only which only uses Edge network .
i have tried every possible thing to resolve this issue but nothing worked for me. please help
What country are you in? What carrier are you on? What bands do they use?
location location location.
Where are you from?
And what frequency does operators in your region operate.
just curious, have you tried hard/factory reset?
i am from saudi arabia and i am using Mobily network.
mobily is using HSDPA network as well as Edge network.
i did a software reset and still the same issue.
phone information:
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
crazy idea - is there any blocking going on in SA or with that carrier? Have you used another not carrier supplied smartphone successfully on that network?
I have been always using their 3g network on my iphone. And still there network only on edge connection on the s2. What i have noticed is that the saved apn sometimes shows up and sometimes disappears

Hi, very similar issue here.
For this four days since I have got my GS2 everything was just fine. The data connection and 3G speed was great. Yesterday, all of the sudden all got crappy. Could not display any web pages. It starting to display page but after few seconds pop-up window appear which say "Data connectivity problem. The server failed to communicate. Try again later"
Interesting that my gmail, market, xda app working fine as normal.
I'm in Ireland on O2 now.
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
Can someone help to solve the problem, please. Is it possible that something with the hardware is wrong? Broken?
I'll perform the factory reset and will let you know.
i just managed to flash my device with the latest EXE1 dated May 3.
and i am still facing the exact same problem.

Maybe we should ask for replacement...
I have same issue, and for Ihrrob, your other application are working fine because what i noticed on my mobile that 3G & 2G connection is there but not permenant that's why WIFI hotspot always disconnect and VOIP applications are not working.

You are right the 3G/2G connection is there but not permanent.
If I press the Internet icon the home page, which is 'Google' appears (sometimes) immediately. I think this is because the page is very light. If I try to open a regular page it loads 1/3 of the content or nothing.
i just hope it is a software bug not a hardware problem
Type on the dialpad *#*#4636#*#* and force the phone to HSDPA only on the dropdown menu. This is a hidden menu on the phone.
Isn't this carrier related?

Unfortunately not.
I have spoke to the rep in the store. They reset all settings for me but it didn't help.
Just to double check if he wasn't wrong I've put the sim card in to my N900 and all data worked fine.
Bad, bad...

I'm on Mobily network in Riyadh, and 2G/3G is working fine for me. I stay on 2G most of the time to save battery, but have tested 3G and got around 3mbps.
I have the same Baseband, Kernel and Build number (rooted)
Are you using "Market Enabeler"? It can change your APN settings, and you need to restore the provider setting.
just rooted my device.
still same weird issue.
issue again: simply whenever my device tries to connect to H+ , the device automatically enters flight mode and automatically disable flight mode so that the signal bars come back without H+ and when i check back the saved APN i see nothing there ( thought i was there before ). and this strange behavior disappears when i switch the mode from GSM/WCDMA auto TO GSM only .. after i do this the device connects regularly to Edge network and i can browse the net.
so basicaly for me i will be only able to use the device on Edge instead of HSDPA or 3G.
im really hoping for help from here because i don't think i will find any help outside of this expert community.
regards
try to make it on obligatory 3G (WCDMA only) and check if the problem still there ..
still same problem juffo
i have noticed that another post are poping up talking about almost the same issure.
i hope a new firmware will fix this
Hi,
Using a N910F with T-Mobile UK, default APN settings for EE. The phone was sold by O2.
I'm having a hard time maintaining a connection to the HSDPA network when out and about, far more so than with my previous phone with the same carrier in the same places. The signal will often show as full whereas the connection isn't established (based on having the 2 arrows highlighted) under the H icon. Once the connection is dropped it takes a long time to re-establish.
I've searched and read about other users having poor reception quality but this seems to be a different issue to the one I'm trying to resolve.
I haven't seen any alternative radios available for this phone yet so not sure if I just need to wait a while. If anyone has working APN settings for T-Mobile UK and can share them that would be really helpful.
Thanks for your advice!
Hi everyone,
I already looked for an answer in the forum but nothing conclusive.
My moto g4 play loses signal during calls. The sim card is 3G and so I changed the network manually to 3g on the phone. However the problem continues and I think it even got worse. It happens especially when I'm moving, in the car, etc.
Is there any real solution for this problem? I have seen many users complaining but I did not realize if there was a solution or not.
Can you help me?
Thank you
Since the SIM is 3G, I'm going to assume the network you're using is GSM (ATT/Tmo). It is possible that the cell towers in your area operate on a specific type of GSM frequency, and your signal loss is due to the phone trying to connect to towers not supported by your carrier. If a call drops again, check the Roaming status of your phone in Settings and see what turns up.
Also, it seems odd that you would have to change the network settings at all. Even if the phone is set to prioritize LTE, it should automatically detect the 3G signal and adjust accordingly.
It's all too frequently dropping 4G or LTE connection when on the move. It's showing a connection, good strength too, but no data connection working. Often needing an airplane mode toggle or reboot to get online again.
5G is disabled as I'm nowhere near a 5G area.
Anyone got any ideas? Different firmware or something?
I'm starting to regret moving away from the SD note 10 plus I had. That phone was rock solid.

I read that some people have issues with connection with some ISP providers. Try putting it on 3G and see if it works fine then. If it does then ISP has either sn issue with 4G network or phone needs a firmware fix to solve 4G connection issue if this isn't a hardware problem thought. Since for me it works fine here and my 4G shows all time and I even have 4G+ as status without an issue.
try disabling WiFi calling that helped in my case
Tried all that. Went into a town and it didn't again.. Had to force it onto 4g to get a connection.

Haven't had any issues myself, on giffgaff. Tried O2 briefly, it seemed okay too.

Give this app a try, might help fixing it to one band
https://play.google.com/store/apps/details?id=com.ray.samsungbandselection
Yes u have that thanks. It seems to be band switching that's the problem. Or is it possible my carrier has live but unused bands that the phone is locking into? So when I travel I find myself with a dead data connection?
