Hey guys,
I've been using my Note 4 for a couple years and it was running smoothly before but now it started showing issue, I hope y'all can help me with these problems..
Problem 1: Dual-Band WiFi Connectivity Issue
My N910G could not connect or even find any 5GHz frequency WiFi connection(neither my home WiFi nor the others),
but it shows no issue connecting the 2.5GHz frequency. My home router is working perfectly fine and my other devices which supports 5Ghz band have no issues connecting to my home router so I don't think this is the router at fault. I've tried reset my N910G to factory setting, at the setup it miraculously connect to the 5GHz band without a problem but as soon as I turn the WiFi off or leave it after a while, it disconnected and it does not show any 5GHz after that.
Problem 2: N910G Poor Cell Signal Strength
Okay, now this is a bit tricky. Recently, I changed to a new cell company and sign up for a postpaid package with LTE data only, the sim card is new but as soon as I insert it into my N910G and reboot it. The signal strength of my phone only range from 0 to 2(which is from -80dBm and above) and rarely reaches 4 or 5(highest) but I still can connect to the 4G network, it's just the signal is very poor. At first, I thought it was the sim card at fault but I tried trying it out on another phone and it works just fine.
Can someone help me out with these two problems? Is it because of faulty hardware or software? Does flashing a new custom rom helps to solve these problems?
i have same proplem with 910f is reading sim card and ther'es no signal :'(

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
Hello all,
I just got my N4 couple of days back. I have this problem where when i connect to a 3g network the signal keeps fluctuating. As in it connects to the network for some 5 seconds i ll have full signal and after a couple of seconds there is no signal it shows emergency calls only. This keeps happening repeatedly. But in the 2g network everything is fine. I figured this is a radio ( i had .48 ) problem and flashed an older radio ( .33 ) still the same. i m looking for a solution 2g network is way too slow. This never happened in my nexus s :/
P.S : i dint have a micro sim, so i got the sim cut into a micro sim, is this the problem do i have to buy a micro sim itself ?

It's goes according to your carrier's cell coverage. If you're in area with low HSPA+ coverage then you will lose it and it will automatically switch to another frequency band. Big building can block cell coverage. Going underground or being in the basement will lower your data coverage. It has nothing to do with your sim card or your baseband.

I never had this problem with my nexus s, is it because nexus s doesnt have HSPA+ ?
Hi, my i9505 has dead power button so i searched on the net and i i bought a not-working i9505 motherboard.
The problem was "sometimes it doesn't connect to the cellular network".
I installed the motherboard, sim was read correctly, insert pin.
All seems fine except it has serious problem registering to the network, and when it does ( maybe 1 or 2 times every 10/15 try ) it can only work in 2g mode, so only edge connection.
When it connectes in EDGE, after a few seconds, it disconnects, i see signal bars change and i understand it's connecting to 3G or 4G. Signal bars comes, but it acts like if it doesn't know how to communicate in that mode.
Using *#00111# i can see LTE freq. which is using.
I already tried unlocking using PERSO SHA256 OFF... unuseful try
Can you help me?
P.S. I forgot to say that IMEI seems fine, efs too.
Hello guys i'm new here and I am confronting a strange issue with my Note 4 Sm910F, the phone works great ultil I connect it to my home wifi, then the nightmare begins, the wifi works very well but after 20 min my network (3G or 2G or LTE, it doesn't matter) drops but I still have all bars, so I cannot make calls or send messages, if I go to Settings>Networks to switch between LTE 3G 2G it doesn't let me, it stays locked, I must restart the phone to regain celular network and then after a while it repeats the problem again and again. I'm sick of it already, also I tried different roms but no luck, I said that the phone have hardware issues sooo NOW the baddest part is that I sold the phone and bought a fresh new sm910F that DOES THE SAME PROBLEM !!!
I tried with another wifi router, still same problem, my old note 3 works okay on the same wifi.... i`m out of ideas.
Please help with any advice. Thanks.
If Smart network switch is active, turn it off.
That's the only thing I can think of that's causing the problem.

Hi everyone, I own this nice terminal, but I have a big problem. When I use the 2g network, since I'm in Italy and in 4g cannot receive calls, the phone has a very low signal and remains completely absent very often. I have the same problem when 4g makes the switch in 3g. Sometimes to recover the signal I have to turn the airplane on and off. It's normal? And does anyone have the same problem or can he help me? Is this a hardware problem? With a Xiaomi Redmi Note 3 Pro in I own these problems do not occur, so I rule out the problems of my network operator.

Also noticing issues with Chromecast .It fails to detect Chromecast and need to toggle airplane mode
With the 7.10.14 i didn't noticed this.
Chromecast works perfectly, also i'm not facing problem with 2/3/4G signal.
Wifi is not that great however.
I'm not going to upgrade to latest version until they don't fix this problem.

I'm in italy too but the modem, so far, worked really well for me.
I'm using vodafone and when receiving calls the signal switches back to 3g (very rarely 2g) but never faced any issue. After the call ends the phone switches back again to 3/4g in a few seconds.
