No Service - Galaxy S II General

Hello,
I've had my phone for over a week now and it was great until yesterday. Now I am unable to make any calls with it but data still works. I have attached some screen shots below. Any ideas on how I can resolve this?
The problem occurred 2 days after I flashed XWKE2. I tried a factory reset, no change. Then flashing to XWKE1, no change. Then back to XWKE2, no change.
Oh and the sim's not at fault, works perfectly with my I900 Omnia.

Ugh... samsung phones. My galaxy S and Nexus S both have this issue and it seems they still don't know how to fix it.
Usually I would just cycle airplane mode on and off to fix it. Sometimes that would cause the phone to never come out of airplane mode though... in that case I had to restart the phone.

O2 are suffering outage on their system at the mo. Just Google "O2 outage" for details.
Started yesterday and is continuing, they have engineers working on the problem.

try changing your radio band to gsm only..maybe that will help for some troubleshooting

Thanks but didn't help. This issue may be O2's fault not Samsungs.

They should really tell their affected customers when something like this happens. This most likely is the reason as I tried making a call using the same sim in my Omnia and it didn't work. Thanks for the heads up.

Thanks, tried it but didn't help.

There was a theft of equipment at a site near London, and it knocked out a large area of the country...
Goodness knows why a site of such strategic importance is unmanned, but it has caused a large blackspot...

Looks like service is back up now, for me at least. I probably should have googled 'o2 outage' before I reflashed my phone, but now I've turned off sending google usage data so hopefully my battery life will improve.

Seems like yours might be more a case of ID TEN T error more than anything else because I've never experienced that on the Galaxy S or this Galaxy S II.

Sudden Loss of Data on Nexus S

Hey guys,
This is actually my first post here but I do A LOT of reading on this forum.
I didn't quite find anything regarding my question (or at least a solid answer), however, so I've decided to post it up.
Has anyone else experienced a sudden loss of data from time to time out of nowhere?
I go from having Full Green 3G bars to grey bars out of the blue. I've heard the green bars is to let you know that you are connected to Google services but I am not able to access anything that uses data.
For instance, when I open up the browser, I receive an error telling me there is no network connection. When I open up anything else that uses a data connection, Market, News, etc, I receive the same error about there not being a connection.
This would make sense if I was moving and going in and out of service areas, but it happens when the phone is simply sitting on my desk and not moving at all. I usually use it to listen to Pandora while at work and have noticed that the songs cut in and out due to this sudden loss of a data connection.
I went from a Nexus One to the Nexus S and have never, not once, lost my full 3G bars in this same exact location. I personally believe its a software bug of some kind and have high hopes for it being fixed in the future. The N1 had similar issues when it first launched and Google / T-Mo were able to remedy that for the most part.
I am actually on my third Nexus S because the first two had some type of hardware issue; the first one's back button didn't work or light up and the second one had a blown ear speaker and would sound like a blown speaker in a car. As an early adopter, I expected this, so it didn't bother me in the least bit.
ALL of them did the same thing, so I know it is not just limited to my exact phone. This is definitely something with the Nexus S in general (or the current build of Gingerbread).
Can anyone shine some light on this situation? Thanks in advance and keep up the great work here guys!
---------------------------------------------------------------
UPDATE: Here are a few steps that I have taken in order to solve my sudden loss of data issue. I'm not guaranteeing this will work for you, but it has worked for me and a couple of users here on the forum.
Do the following:
Activate / Use the Sim Card that came with the phone (this is to ensure you are using the latest sim cards)
Make sure you have a 4G internet plan. (No t-zones, No web2go -- FULL internet only)
Call T-Mobile and have ask them to Reset your phone with their Towers
Here's a more technical explanation posted by Johoja:
1) Having network selection set to manual ( i.e selecting 302490 or TMOBILE) will result in No Service on a reboot. Solutions: - Have to cycle airplane mode to get it to pick up service (can be done with automatically tasker) - OR Use automatic network selection. (you can force wcdma only but that will reset the SMSC which is annoying if you go in and out of wind away/home areas and you want to roam.)
2) Being in a area with no service for extended periods of time 5+minutes(subway, basement, etc) will result in a dead baseband, meaning once you come into an area with service the phone will not reacquire signal, airplane mode will not work as the baseband is now crashed, cant maunally search for a network. Have to reboot to get signal. Solutions: -Use tasker to cycle airplane mode on and off when in no service areas i.e) search signal 4 minutes, airplane mode on 10 minutes. This will keep the baseband from crashing and possibly save battery. -Use NoBars to accomplish thesamething ( taskergivesyou a bitmore flexibilty of course but harder to use) http://www.appbrain.com/app/nobars-b...omdryer.nobars - Use airplane edit to avoid turning wifi/bt off when airplane mode is on. http://www.appbrain.com/app/airplane...kalti.airplane
3) WCDMA perferred does not work. - No solution
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=747f398a6c1bb2b9&hl=en&start=40:
I read one users response on a different thread regarding something similar to the issue that I am having.
They said T-Mobile told them to get a newer sim card and that this may remedy the problem. In my case, this has been the only constant in the 3 phones that I have been through. I have had the same sim card for about 3 years or so now.
I will try activating the sim card that came in the box with T-Mo to see if this remedies the problem. Since I'm at work right now I will have to try when I get home later.
Does anyone think this will have any affect what-so-ever?
The galaxy s phones when first released, all variants, had issues of signal dropping from full to zero bars while sitting in one place. I remember because there were YouTube videos of it All over and it was shortly after the apple antenna issue.
Not sure if or how it was ever resolved. But it seems that Samsung may just have this type of radio baseband performance if we see all these individual units doing this. I don't know maybe others can respond.
I have the same issue as the OP. I travel to the same location weekly with NEXUS ONE, signal never drops in the T-MO Country here locally, and streaming CNET POD CAST never a hiccup, however, with the new NEXUS S, I would lose DATA Connection only, while the 3G will show full signal. I had to reboot the phone to get the DATA back.
is it the S issue or 2.3 issue?
food for though....
If you have T-zones or Web2go or Phones 1st web, you will have problems
I had the same problem too, now I fixed the problem. The thing was that had the wrong data plan on the NS, i had my old web plan from my hd2 which seems like different from the one for the NS. I restarted my phone after 5 mins off and now i have my internet working beautifly. A T-Mobile rep said that it was an error in the system that made the phone think that that was the right plan for the NS for a few. A glitch you may say, but all you have to do is put the right data plan that all, easy. Hope this helped and have a wonderful holidays everyone.

this is happening to me too, last night for a little while and today for about hte last 4 hours can't get connection back. i have full white bars, with 3g icon but can't access anything
So I activated the new sim card last night and I'm still having the same problem. Albeit it doesn't happen as frequent, but it still does it nonetheless.
I will call T-mo again to verify my plan. I am on a 1500 Minute Family Plan which includes unlimited data and messages. I will see if they need to tweak something and let you guys know if this remedies the problem.
Ok, it seems like the issue has been resolved after I spoke to T-Mobile earlier today.
The rep on the phone verified that the data plan I was on was in fact the correct one. He said he was going to reset the signal from the towers to my phone to see if this would resolve the issue. He asked me to turn my phone off for about 15 seconds after we hung up.
Since then, I haven't seen the problem arise again so my guess is that it somehow fixed whatever was going on.
I'll let you guys know if this changes and the problem occurs again.

What's with the CAPS? ?
On topic: i have a captivate and I can confirm that all galaxy S phones had droppend data. An official ota update fixes it so maybe you guys need to wait for something official. Isn't there a new firmware for the nexus S already? Try flashing that and see if you still have issues.

Doesn't every android phone from samsung have this problem?
I know the Moment has that problem, after 3 updates samsung called it quits, I still have to reboot mine 2 to 3 times a day for data lockups.
@timur525 Yea, I'm already on 2.3.1.
I manually updated the first hour it came out hoping that it would solve the issue. The problem was still there after the update.

I have exactly the same issue as the OP. Extremely annoying to reboot the phone every time it happens. One thing I have noticed is that my phone doesn't know its number. If I go to settings, about phone, the number says unknown.

That shouldn't affect anything. My number shows up in status.
I had this issue resolved a few months ago as the push-to-talk app Tikl requires this in order to use it.
I was having the problem even with my number showing up. Call T-Mobile and have them reset you with the towers like they did for me and see if that helps you too.

I posted about this same issue on wrong section of the forum. Ive had this issue ever since samsung vibrant. I have applanet installed on my phone and some of the app that i installed accessed my apn and totally changed my apn setting to "Sirious application disabled.epc.tmobile" or something like that so i wyped everthing off from the phone and so far i havent had the issue ever since yesterday. Also i had the locale and language setting to korean so im thinking that might be causing it also.

That's what I remember too. I think its just an issue with the radio Samsung uses in all their phones. Might not be a way to fix it if even their new phones like the nexus s still have this issue. They prob would have tweakdd it by now if they could.
Same problem here. Xmas eve on shift and I have a phone that had no connection whatsoever (not even phone capabilities) this may be the one thing that takes the phone back. (If it happens again)

Have you called T-Mobile to see if they can give you a reset to the towers?
I had this done yesterday afternoon and haven't had the problem again since.
Also, if you'really using an old sim, I would suggest activating the one the phone came with just to be on the safe side.
If that doesn't help you then I would at least wait until just before your return period ends to see if there will be an update to address the issue.

[Q] Error sending/receiving MMS "National access coverage not available."

Hello,
Lately I have been unable to send or receive text messages that contain pictures or videos. The error message is always the same "National access coverage not available."
I called Verizon, on Thursday of last week (1-13), and the technician was unable to figure out the problem. He escalated it to the next level and said that someone would be contacting me in a day or 2. Well it's now Wednesday (1-19) of the following week and so far, nothing!
Has anyone else run into this problem? If so, what's the fix? Any help would be appreciated, especially since Verizon has been no help at all!
I'm using a Moto Droid2 ver, 2.3.2 Rooted and OC'd @ 2.25Ghz
Thanks,
Scott

Thanks for the reply.
Unfortunately, it didn't work. I updated it waited the 15 minutes. When it didn't work I rebooted the phone figuring maybe it needed to be refreshed or something, (long time windows tech, reboot fixes everything!) but still nothing. Just that same message.
I get the exact same error when sending or receiving MMS 50 percent of the time with the first initial try... *228 does not fix this.. verizon cannot fix it either...
OK, got tired of waiting for Verizon to call back. On the phone with 2nd tier support now for about the last hour, so far nothing.
Mine started doing that on mms after using juice defender app and I had to do a factory reset to fix it.
OK, got finished with the Verizon tech, who was very helpful, but we still could not resolve the issue.
She removed and reloaded my data from the server, switched me to another IP address and did a few other behind the scenes things but nothing worked. She suggested doing the factory reset, but I'm ready to give up troubleshooting this issue yet. If all else fails, then I guess I will have no other option.
Since sending MM text's in not a huge part of what I use my phone for, I may just wait for the next release of the software and hope that fixes it.
In the mean time I'll just keep playing with settings and searching Google and the message boards in the hope that someone can come up with a fix that doesn't involve having to wipe it.

I used to use that app, but removed it long before this started happening. I wonder if it left behind some orphan files that are somehow in there wreaking havoc?
Since the problem still existed even running the phone in safe mode, I would think that would not be the case, but anythings possible.
my phone does the same thing with same message... if i try again to download message it will usually come through, but if it happens on outgoing message it will never go through

That's the thing. Since so many people are having the same or similar issue, I just find it hard to believe it's not something on Verizon's side or with their software. This many people screwing up their phone's in the exact same way all around the same time just seem a little suspect to me.
Mine happened 6 months ago. Just reset it and see what happens. All your apps with reinstall by themselves.

Yeah, I guess I'm going to have to try something. I want to make a nandroid backup first just to be safe and then I'll give it a shot.
Thanks.
This is great!
So, I just finished the factory reset (which DID fix the problem) and was starting to configure all my custom settings when the Verizon tech I spoke with called me back. She said that she had just spoken to Motorola and they said it was a known problem with their phones! They are not sure what it is yet, but they are working on it. In the mean time, the only thing they can suggest is to reset the phone as a work around!
I asked the Verizon tech if there was any kind of documentation about this that she could send me, but of course there isn't. And there's also nothing on the Motorola site about the error either, at least nothing I could find.
While it doesn't make the situation go away, it does make me feel better knowing what the root of the problem is, sort of. Only problem is, there is no guarantee that it won't happen again.
i turn airplane mode on then off... works for me
Im having the same problem. I even reflashed to stock motorola, still does it. I noticed if i hold down on failed pics or tap download a few times it works. The problem seems to be triggering the data on and off from the send button.

Yes, I had heard that worked for some people, and I did try that but it still didn't work. Even so, that would only be a work around and not really fixing the issue.

Interesting, since I did the factory rest I haven't had a problem. If it happens again, I'll be sure to check that.

[Q] Moto Defy + call drop straight after dial while in 3G.

The minute I turn on my 3g any normal voice calls made from my phone gets disconnected within a second.
If I switch to Wifi / 2g the issue is solved!
I have tried Settings - Call Settings - Additional settings - Caller ID but the option of caller id itself is unselectable!! I have read many people saying to select caller ID and set network default fixing the problem but on my phone it is unselectable!
Please advice on how I can fix this problem! Thank you

No I am running stock 2.3.6 and havent done any updates since I got my phone 6 months back! The problem is still not resolved!
I beleive it is a problem with my carrier Airtel as they say that there is 3g upgradation going on in my area. But I still face this problem all around Bangalore!! I cant understand what is the major cause of this problem! I have used my sim in my friends Sony Ericsson Arc and there is no issue whatsoever! Im still waiting for a solution. Please lemme know if you find anything as well! Tx
I don't think its a problem with airtel because I'm facing this problem with vodafone, I m facing the same problem with airtel sim also in the same handset however same sims are working fine with other handsets.
Initially vodafone told it might be a problem in their network but after checking they confirmed that there is no issue with their network.
I feel its an issue with phone itself but know its related to hardware or software. Factory reset also didn't work, tried all possible ways that I could think of including replacing sim but no lucktill now.
I took phone to motorola service too, all they could suggest was to replace sim and factory reset which I've already done, only solution left is to give the phone for checking and they need 2 days to check if any fault is there.
Did your phone always had this problem or started recently? Do u remember making any settings in phone before this problem started?

You're right.. I guessed the same! Well this phone has been giving me this problem since January of this yr. Before that it was perfect! I cant remember making any changes in the settings. I have also done a factory reset but the issue isnt solved. I cant understand what to do now?! this really is getting irritating cause every time i have to make a call i switch off the Data using toggles widget and turn on again once done. I cant do this forever. Even the calls which I get from someone else gets cut in a second and appears as a missed call. I desperately need someone to suggest a cure for this!
Do let me know if you have made any setting changes recently . I ll try to remember if there is any common changes we have made and try to find a solution for this.

I also want to state that when my 3g was on before the issue began it used to be displayed as H - meaning high speed internet. Since the day I ve been facing this problem the H symbol changes to 3G - once this transition takes place immediately call gets dropped. I ve never seen the 3G being displayed before the problem.
Question: Does the 3G have to be switched off automatically once a call is made? Like for eg. if you re connected on wifi, even when you are in a call the wifi is still on and active in the background.
Is the 3G supposed to switch off automatically once a call is made just like it does when in 2g??
Some of the things I remember which happened before this problem started are:
1) I updated the firmware.
2) I kept a heavy bag on my phone by mistake.
3) I changed the phone's battery, I'm now using the an extended battery bought from eBay.
4) I changed the screen guard, using a matte finish guard now. (wondering if the solvents that they use while fixing the screen guard have any impact on this)
5) I started using the application Team Viewer a lot to operate my home laptop from office.
I've mentioned everything that I could think of, is any of this matching with you?
Its was a very good handset till this problem started, I don't want to buy a new phone just to fix this problem.
One more thing I observed is that this problem has increased over time, initially when this came to my notice 50% of the calls got cut while using 3g, but now all calls are dropped while using 3g.
The calls - both incoming and outgoing are working fine even if 3g is on but no data is being transfered. Once the call is connected 3g works fine. The problem is only in starting/initiating the call while 3g data transfer is happening once the call is connected 3g is fine.
Regarding my usage:
I've been using this phone very roughly from past one n half year, I use it regularly to download using both wi fi n 3g, I listen to music everyday using bluetooth n also watch many movies on my phone itself.
In short usage is very high n rough.
Could it be a wear n tear damage because of this?
Pls let me know if any of the mentioned points match with you which will help us locate the reason for the problem.

Well Sry but nothing in common! For me since the beginning of the problem, 100% of the calls are getting dropped! its been a month now. Do you face this problem in a specific area or all over town? Ive searched a lotta forums for an answer but to no avail! I dont know if rooting the phone will help!?!?! but that is my next step. Did you try going to Settings<Wifi and Networks<Mobile networks and selecting 3G only? FOr me the problem persists but i guess you should try this.
Hmm, problem is all over the town.
I've also selected 3g only in settings.
Even I'm thinking of rooting my phone but I'm afraid I'll brick my phone.
How are you planning to root your phone?

I ve posted on a forum for rooting advice as well! Still confused on which procedure to follow. The cm10 JB from Quarx sounds promising but only for defy MB525! Lucky you. I still have to wait for the MB526 which is not yet stable!
Thanks, can you pls provide the link to the page where step by step rooting instructions have been provided..
Do let me know if you come across any solution or workaround for this problem, I'll also update you if I get any..

Ive given my phone for service today. Hope I ll get my phone fixed!
Great, let me know if its fixed. I'll also get it done.
Rooting seems to be complicated, didn't do it as I'm afraid of briking my phone.

I gave my phone for service yest and I am expecting it tomorrow in the evening. Will Keep you posted on the update.
Same problem
I am EXACTLY facing the same problem. I have an AirTel sim and I don't remember from this problem got started. I tried restoring factory setting, flashing the phone in authorized service center and nothing helped. I was about to install custom ROM and just read this thread in the forum. I will wait for some more time to see if any of you is lucky enough to find a solution for it.
As a temporary workaround, I have changed the GPRS to 2G and its working now. In 3G, if I try making calls, the data connectivity will not be cancelled, but in 2G, as soon as you hit the green button, the data will be cancelled.
Please reply if you find any solution for it. Thank you!
Solved!

1) Does anyone of you NOT use motoblur Account????
2) Does anyone of you NOT use google account in your phone?
I think the solution lies in the questions above. If you use either one, the problem will persist. Try to factory reset your phone and skip log in Motoblur and Skip google account sync. The problem should be solved.
No luck
As suggested by you, I did a factory reset and tried making call without adding Google account and it didn't workout. I had the same problem. I even tried adding another Google account (after wiping data) and same problem. I lost hope
I am gonna use my mobile with 2G only till someone finds a permanent solution.
Thanks for your help!

Factory t-mobile S7e losing mobile network connectivity

so this is the second S7e and second SIM that I have been having this issue with. The phone will lose connection to the mobile network and the ONLY way to recover is to reboot phone. Reset Network Settings doesn't do anything. Toggle airplane mode doesn't do anything. Search for Network Operators doesn't do anything. I have a third phone on the way - but has anyone around here heard of or experienced similar? Am I missing something that I should be doing to correct this?
Thanks in advance
I too have this problem. Got a replacement refurbished phone under warranty and the phone has this problem

Did you pay the $20? I didnt want to pay the 20 so i sent the device to samsung. Should get it back friday or monday. The issue is definitely phone related. Im using a verizon s7 now and no issues like that arose. I even tried new sim.. My father is having same issue t-mobile s7 edge
Yes i had to pay 20. And it's disappointing I am having this issue with the replacement phone. I am having this problem on the U firmware as well.

I've suffered the same issue from time-to-time and just do a restart....annoying as hell to be honest
Are you guys always in the same location when this is happening or is it just whenever and wherever? Or is it happening a one certain place where cell signal isn't that great? I had this same issue BUT only in my house so I had to get a network range extender from t-mobile to use at home.
This happens to me all the time. It's so annoying. At work, in the car, at home--it doesn't matter where I am. Have reset firmware multiple times and even rolled back once too. I think it has to do with the latest software because I never had this issue before the Fall/Winter. Hopefully Nougat fixes this!

I happens randomly in different places. For me i lose complete signal, and then only get back signal without data. I have to restart when this happens to get back data. Annoying as hell !

I am having the same problem, this will be my 3rd phone 4th sim. I wish I knew how to fix it
I would try flashing different radios/modems, its worth a shot. Maybe try flashing the "U" firmware radios.
Nougat will fix it
My wife and I had the same issue on our tmobile s7 edge ... we got the 7.0 beta and now the issue is gone .... I bet it's radio and software related ... 7.0 will be out by the end of the month hope that helps...
I had this issue with my phone, and it was a huge pain. The biggest concern: I didn't know when my phone was off network (voice, data, etc.). The fix, for me, was simple: a new SIM card.
You may have an issue from a rejected permission on an app.
Had the same issue before but I did a hard reset and realised that I changed permissions on an app that wasn't written for 6.1.

I hope so! Been waiting for that before I try anything drastic, even though this issue is a huge pain in the ass. I'm glad others have come out of hiding to express their concerns with it as well. I thought I was the only one for the longest time having this issue.

Many of us have tried new SIM cards, but it's worth a shot if it's still not working consistently after Nougat is released.

My and my friend's phones are both running pure 100% OEM Tmo stock without any apps disabled or touched at all and we have this issue and have done multiple resets. Pretty sure it's an actual hardware defect, or hopefully just a software one with the modem/radio.

I was thinking about going that route. But I wasnt sure what condition the phone would be. How was you condition?
I sent mine to samsung and the things they replaced is the Coaxle cable "antenna" replaced 3 of them. I have been using the s7 from verizon on the U firmware so havent seen if it is fixed.

I received a refurb. Other than this problem, the phone is alright. I noticed this problem on receiving the phone it was running on T firmware. Then I switched to U firmware and radio but no difference. I called customer support yesterday, they said to go to a retail store to get the phone replaced. My worry is going through this process again and if I receive a bad device again what to do? After all refurb phones are like playing Russian roulette!

I just had this start happening on mine... I really wish they would release nougat already. It is ridiculous they won't post an Odin flashable version of the release candidate if it does indeed fix the issue.
I also think its a specific tower configuration that is causing the issue that the radio can not understand. (Maybe 3xCA). Its happening in the same areas every time.
I just started having this problem in the past month. All at once I've been getting BT sometimes turning off, mobile networks failing to reconnect after I visit a no/low signal area (such as after a plane trip when the phone was in airplane mode). I've also seen wifi mode fight my attempts to turn it back on sometimes - toggling itself on and off a couple of times per second until I poke at enough settings to stop it. When BT turns itself off I have trouble turning it back on, sometimes it just goes back on, sometimes it refuses after a number of tries and if I wait an hour it goes back on just fine.
The folks at a BB Samsung kiosk said they could reflash it if I wanted to go that route, but that the nougat release would be out soon so it might be better to just wait for that. Has anyone had a Samsung rep re-image their phone to try to solve this?

If you were able to fix without a reboot you didn't have the same issue as this.

I guess I wasn't clear about that as I have several problems that are probably related, but behave a little differently.
BT dropping - can usually turn it back on, but sometimes it refuses. Usually don't need to reboot to fix this.
Wifi dropping - often have trouble turning it back on and have seen the widget toggle off and on repeatedly by itself. Sometimes have to reboot to fix that.
Mobile Network data (and voice sometimes) dropping - usually have to reboot. I think I may have recovered that once without a reboot, but the other few times it's happened in the past month since it started I have rebooted and that fixed it in all but one of the reboots - one time I rebooted and still had to fiddle with it a bit after the reboot before it came back. That may have been because I played too much with the network settings before the reboot and so had to undo that damage after the reboot. But, definitely rebooting is a fairly reliable step in fixing this problem.
All 3 started happening around the same time which is why I thought it was a software issue (I remember a small update a little over a month ago, but forget the details of it). It's nice to hear that others also have the mobile network problem, but if that is isolated in those cases then maybe I'm not seeing exactly the same problem. But, it is clear that rebooting is almost always required to get my mobile network data back so that again suggests that at least that part is the same as what this thread is discussing.
In looking at the T-Mobile updates page for the S7 Edge I see that the version I have (G935TUVU4APK1) was updated in early November - which tracks when I started having problems, and it includes a fix for "Domestic data roaming improvements", which definitely sounds like they may have played with the radios.
I am so ready for the Nougat update...

Wifi issues?

Sorry if this has been discussed before. I just can't find it anywhere.
Is anybody having any Wi-Fi issues with their S8? What is happening for me, is that, I connect to my home private Wi-Fi network. Then 10 seconds later the network completely disconnects. Then approximately 10-20 seconds later it reconnects again. It keeps doing it over and over and over, non stop in a cycle. So I completely disconnected from my Wi-Fi, and I'm using my 4G LTE. I started noticing this at home, but then as I go to other to other Wi-Fi networks it's he same issue.
I even did a factory reset to the phone because of this issue and a home button vibration issue, where the vibration would not stop even in standby mode. It was also causing the Android OS settings to even be disabled, and not let me go into the OS serttings from the Android OS taskbar menu button, or the button for the settings in the app drawer. The factory reset did fix the vibration issue, but it didn't fix the Wi-Fi issue at all.
Also, is anybody else having this exact specific Wi-Fi issue I'm having?
Thanks in advance for all the answers and feedback!

You need too update your phone through the Samsung Apps app. Samsung released a fix for the wifi issue.

I already am up to date with all the apps in the Play Store and the Samsung store. I even contacted Samsung, and the woman on the phone on her own just completely connected me to a manager without saying a word to me. The manager ended up saying that he never heard of this and made a bug report so they could look into it. It's also not in their system, according to this manager. This was today around 5PM EST
It could be a hardware issue. Have you thought about exchanging it?

I already did. This is the second device to have the Wi-Fi issue. I just received my replacement device in the mail today around 4PM EST, which is the device I'm talking about here.
The thing I'm thinking is, that maybe if I went back to the direct cell phone providers store and did a buyer's remorse exchange. It could just be a batch of phones that have the same issue. Which more than one from the batch could be located at the same store. But since I'm in Florida, and the replacement device came from somewhere in Pennsylvania it's a completely different batch. Which the Samsung manager agreed with me. He even told me what I already know, that even if Samsung tests the phone. People in the real world using the phone, may encounter issues that Samsung never found on their own. He also went on to say that it's vital, that people in general, especially people that are tech savvy and semi tech savvy call in, because with us calling in it can help fix the issues that Samsung may have never encountered on our own. The manager also said, that there can be more people with the same exact issue, they just never called in and reported it like I have.

What kind of router are you using? Have to tried another? Go to a Starbucks, or some other free WiFi spot and test. So far with you it's been a 100% issue. I'd start looking at different things.

Like I said in one of the above post, that I noticed it at home first. But as I used other Wi-Fi's I noticed it was an ongoing issue. I've tired my home private Network, my work private network, and at a few friends houses.
The manager from Samsung, honestly believes that it is a Android OS bug.

It's not a big deal, I completely understand. So what else do you think I should try?
I also have issues with Wi-Fi similar to yours, if anyone has a solution, please let me know
Have you made sure that in settings you have a tick on "Keep wifi on durring sleep" ? Also for the sake of it, switch off "battery optimization" for all apps and see how it behaves. Also make sure you swithch​ off the option "smart network switch" under WiFi settings. What your phone is probably doing is constantly trying to switch between the WiFi and mobile data, or the power management puts it in sleep to preserve battery.
Well instead of getting the same same old suggestions (which Im sure you tried, all of them) you can read thru them all here in the thread that already exists:

Keep Wi-Fi on during sleep is activated. But it has nothing to do with that because my phone goes to standby mode in 30 seconds. While as soon as I connect to the Wi-Fi network, 10 seconds later it completely disconnects me. Then 10-20 seconds later it reconnects me. Then it repeats the same thing over and over. The phone can be completely in use, or it can be in standby mode, the same problem still occurs. Also the same thing goes for battery optimization, while it's on and off.
It also appears that someone else on the first page is having similar Wi-Fi issues. So maybe, a few of the many mass produced phones are having Wi-Fi issues. So maybe it's really an OS bug like the manager from Samsung on the phone yesterday was telling me.
Hi All, even am having a same problem, am here in Saudi Arabia and when i spoke to samsung Persons they are not showing an exact root of the problem and not even willing to exchange my mobile. this issue is with my mobile since 3 months and am waiting for upadte , i got 2 updates till now but none solved my wifi problem, i donno what to do
I can say this only happens to me when I have Bluetooth on and my watch connected and when I'm on a 2.4 signal vs a 5....and if by chance is your phone with sprint or verizon?
