QUESTION: Marshmallow failed to connect - Samsung Galaxy S7 Questions and Answers

Constantly, I get a 'failed to connect' bug on:-
Facebook
XDA
Spotify
Rarely chrome
Gmail
- and any app that uses the internet for a prolonged peroid of time. (Especially annoying on chromecast)
Even with wifi and 4g switched on, i sometimes get the annoying 'unable to connect' message until i close the app and start again.
I've slithered around the net, I've found similar posts with mixed responses and fixes that all fail to work. - I even went to restoring my S7 and using it with stock settings for a week just to ensure it wasn't any misconfig'd settings, or power saving settings, but sadly the ONLY improvement is that spotify doesn't DC anymore.
Has anyone having these issues with marshmallow come across a fix?

Wifi connection connected but won't load pages

It said connected in the wifi setting and it shows bars but it just won't load any website in the browser .. anyone got a fix for this?
I have the same issue. Tried different combinations of restarting wifi, turning on/off cell data, on/off wifi calling, etc... all with no result. I've also tried on different networks (both public and private)-- it'd start working for a while and then all of a sudden stop and never work again.
Seems similar to the problem here: forums. t-mobile.c om/t5/T-Mobile-G2x/G2x-WiFi-DNS-issue-not-the-4G-switching-one/m-p/831439 (sorry there's a new user no link restriction)
Does anyone have any suggestions?
Thanks

is it specific to the browser or can you not move any data?
Idk, whenever I have had problems connecting to the tmo network, which is a separate issue.. it was always that wifi calling was still on even tho wifi was turned off. Every time I had probs w/ data on tmo network, it's been wifi calling.. Your case seems to be diff tho.
Is it specific to just your network or all other networks? Try shutting off wifi, reboot... then turn it on again? Idk.. just tossing out ideas.
Some found the root cause and I am posting his finding as I do have the same issue and can reproduce the error:
I think I have discovered a new WiFi-related bug in the G2x's software. I have witnessed this occurring on my phone, and have also reproduced it on a store demo unit. I believe it is unrelated to the switching-to-4G problem people are having with the My Account app, since it occurs even if I have set up the Google account on first boot after a factory reset.
The details of the problem are:
- Every so often, the phone randomly gets stuck in a state where it is not able to initiate any new connections that are made using a DNS name. Attempting to navigate to a web site, h**p://w*w.google.c*m for example, will result in a generic failure message.
- However, attempting to connect directly to an IP address instead of a DNS name works perfectly. For example, navigating to 74.125.225.16 will work fine and will load the Google home page.
- When the phone is in this state, using a DNS lookup tool such as "DNS Lookup" from the Marketplace *will* work, even when using the default DNS server address that the DHCP server is giving the phone.
- The problem has occurred for me when data is off and WiFi is on. I do not know if data being off is a requirement, since this is the way I usually run the phone, so this may be coincidental.
- Switching WiFi off and back on again will *sometimes* work to solve the problem, but sometimes will not. When this doesn't work, switching WiFi off, then switching data on, then back off again, and then finally switching WiFi back on again will occasionally correct the problem. However, I have seen situations where none of these things worked, and the only way to get DNS working again was to factory reset the phone.
- I haven't figured out the exact pattern yet, but this issue seems to occur when the phone has been inactive for a certain period of time. I have often discovered that the phone is in this state upon waking up in the morning after leaving the phone on the charger overnight.
- I have, however, found a method to reproduce the problem that seems to work fairly consistently:
1. Turn WiFi on, and data off.
2. Power cycle the phone.
3. When the phone starts up, start the browser and attempt to browse to w*w.google.c*m. It should fail.
4. Try to browse to 74.125.225.16. It should work.
Just wanted to get this issue in the forums to see how many others have been noticing the same thing.
I know that once the device has less than 10% battery it automatically turns the WiFi off to save battery power. Were the devices this was happening on have a low battery?
Fully charged. It even happens when pluged in with the charger.
My Wifi wouldn't even work if I froze it with Bloat Freezer. It has to run in the background for wifi to work. I found that Wifi can get really inconsistent with it disabled.

Same problem here. After about 30 minutes of being idle, as soon as I pick up the phone it tries to connect 2g/4g. The log are saying theres no connection, so it appears that wifi its going to sleep and not waking up so android is trying to connect 2g/4g
Really starting to be a pain
I have frozen the bloat, and I think the problem is getting worse.
Toggle airplane mode is a quick workaround to get wifi to wake up

Same thing happened to me, I did 2 factory resets, and it seems it has been fixed, don't really know what causes it.

This may or may not be related, but...
It looks like I found a hacky fix for the dns/wifi/4g bug: install "Set DNS" from the market.
Now when I go into market, and display my downloaded apps, it jumps from wifi to 4g then back to wifi as it should, fast.
Whether or not it should even do go to 4g is debatable, all I can say is my 2 Galaxy Tabs had the same behavior.
If everyones connectivity issues are really due to the DNS settings getting wiped out, then this will work around the problem until I/we find the location of the actual bug.
Would you guys having this problem also post it here?
http://www.lgforum.com/forum/boards/general/lg/topics/g2x-wifi-problems
Thanks.
I figure the more people that post there, the more the chances are of LG fixing it quickly.
Work around:
enable airplane mode
reboot
enable wifi
wait a few seconds after the wifi connects, background crap stops
disable airplane mode.
The set dns app looks like a winner. Haven't tried it but that's what's
wrong.
The freezing and other suggestions are all useless crap.
Updates...
I did a factory reset and installed JuiceDefender (I don't know which one worked) but it seems to be all fine now... will update if things become problematic again
I've been having this problem as well. I've always been able to fix it by toggling WiFi off and back on again. I downloaded SetDNS and when it happened again last night I tried that and it worked great.
Glad to see it's a software problem and not a hardware problem.
same problem here. hopefully it won't happen in cyanogen mod

This fixed the problem, at least until the next time I reboot my phone
How do you use SetDNS? This software bug in G2X reboots my router (DGL-4500) sometimes.
Question bout SetDNS app
Does the phone have to be rooted to use the setdns app? I try to use it but it says "Cannot get root. App will not function."

[Q] WiFi strange behavior

I got my daughter her tab 7.7 about 6 months ago & had been going on perfectly. Android version is 3.2 & I have no easy measures to update for the time being.
For internet connection she uses only my WiFi secure connection. It was working fine all this time.
Today she can't log to her Facebook account via the Facebook app. I checked it out to find that I can log in via the browser but not the app. I thought it may need updating and tried Google play store but I was astonished to find it not working too as it gives me "No Connection. Try again".
I noticed that the WiFi mark is white & not showing the green strength marks, but connection is confirmed by the WiFi name. I was shocked when I tried the software update from "about" when it gave me the "no connection message" despite working WiFi connection. Samsung app is working perfectly & I can update its applications.
Also funny thing happened, when I tried the browser it kept giving me certificate errors many times.
I tried the VPN as I googled around but nothing changed. Same problem.
Switching off & on didn't help either.
Any Clues??
Thanks
Most strange thing happened.
Everything is back to normal without me doing anything.
I left the tab for a while while writing the previous post.
When I came back I found the app update mark showing up, I turned on the WiFi & touched the update icon, the strength signal showed in the WiFi & update started the goggle app. All went normally. Facebook app worked & even the browser certificate errors disappeared. The software update in the "about" worked fine & checked & found no updates.
What is going on...
Can anyone explain to me what's happening?
Thanks

Try Power Cycling your modem/router. That often corrects connection issues. Presume other devices were connecting just fine?

Notifications coming in at the same time.

So I just got the phone a few days ago and I've started to notice some strange happenings. Whenever I get notifications for my apps or messages they always come at the same time. Say I have a text message come in, it will then push facebook or something like that and show messages that I have from the messenger app. Is this normal behavior?
@Demonlinx This has been happening since the first day for me too. I've noticed this only happens when I'm on WiFi, if I'm on data I get my push notifications the moment they happen (all except Google hangouts for some odd reason). I don't have the Facebook app installed but this is a constant annoyance I've been dealing with for a while now, it seems as if when the screen is off its not pulling in data when connected to WiFi, but as soon as I get a text message or turn the screen on my notifications come rushing in all at the same time. Are you on WiFi too when you notice this happening? Or is it all the time?
@elpindian Ok, so I noticed that this happens only when I'm on WiFi as well.. Although it seems intermittent because I've been getting other notifications via a wifi connection, i.e Twitter, Snapchat, etc.. So I'm not sure what is causing this issue. I'll keep trying to mess around with it and see what I come up with.. Are you stock? Do you have connection optimizer turned on? Mine is off. Tl;Dr I only notice this happening sometimes and it only happens (so far) on WiFi.
edit: I found that if I enable WiFi and Mobile Data at the same time it seems to eliminate this issue, I'm trying to test using just WiFi and seeing if the problem still exists.

Try a data reset by dialing ##72786#
@Demonlinx I am stock with no plans on rooting until there is a fully functional AOSP rom out there for our device. I have disabled connection optimizer as well, but haven't turned data off even while on WiFi. Is there a specific setting to do this besides the disabling data option? I never turn my data off since I have unlimited, does connecting to WiFi automatically turn off data? Because I know if I did turn it off I wouldn't be able to receive MMS and I definitely still get all my MMS with no problems.. Snapchat and twitter have delayed notifications when I'm on WiFi but work flawlessly when I'm only on data.
@Soooperstar thanks man but I've been told by a Sprint and Samsung rep before to try that and still I have these issues... Could it maybe be a problem on our router's end? I've noticed that this doesn't happen with every WiFi connection I have; i.e if I'm at my gfs house who has her at&t router vs my Comcast router.. I've also noticed that if my screen is off for more than a couple minutes while connected to WiFi my android wear watch will give me the offline message if I try and interact with it. It's as if the phone stops any internet connection while it's sleeping, somewhat annoying because I can't just walk around the house and expect to receive notifications on my wearable without waking up the phone (phone calls and texts excluded).

Could be..... Kinda hard to troubleshoot. The only one I have a problem with is Tapatalk and XDA app. I think that one may be related
@Soooperstar it's weird, I think it has something to do with the phones deep sleep issues and Sammy has yet to figure out all the bugs. I love the build of this phone but can't stand the software. I'm ready to move on to a Nexus device when the next one releases.

Internet connectivity issues

Does anyone have a problem with their mobile data sometimes not working? For example sometimes when I launch Google maps and go to search it will say "cannot connect to Google maps, try again later." I then have to close and reopen the app a few times before it connects. This also happens to my reddit app where I have to refresh a few times before it detects I have a connection.
I'm currently in the US on t-mobile. I tested and have received this problem with stamina mode on and off.
Try it in safe mode,hold the power off menu to reboot in safe mode.
I have had similar issues on .200 firmware, especially with the Facebook app. I don't recall having the same problem on the .152 firmware.
Do you have the same problem with the Facebook app?

I don't have the Facebook app installed.
This connectivity issue happens regardless of how many bars of reception I have. It could show full bars and the 4g sign and it will still happen.

Question Whatsapp Web not connecting when phone is locked

Hey guys,
I just bought the S21+, overall great phone except couple of issue with Android Auto and Whatsapp.
I was able to fix the Android Auto issue (wouldn't connect, had to remove the latest Google Chrome updates) but the whatsapp issue is above my paygrade.
I scanned the QR code and everything works but as soon as the phone screen goes black, whatsapp is slow and disconnects often. Not completely disconnected as after I send a message perhaps 10/15 seconds later it gets set but still not responsive as before (S8+)
Any idea?

Hard to say.
Have you network/internet connection issues?
Are you connected via WiFi or mobile data?
You should check connection settings. Try if it makes a difference if you are connected via WiFi or mobile data.
And if you have installed an adblocker, try disabling. Just to be sure that this is not the culprit.
And I would check for system and app updates.
After you running stock Samsung firmware? Hopefully not disabled any system app.
And the issues with WhatsApp are in the Android app or using WhatsApp desktop on a PC?
EDIT:
Now I have seen the title with WhatsApp web.
Do you have the same issue with WhatsApp desktop app on PC?
The smartphone needs internet access, so if it's locked, it still should be connected to the internet. So you should check the (energy saving) settings that WhatsApp and internet access well not be set to standby when the phone is locked.
I think I have been able to resolve this issue for me. I have Samsung Galaxy S20 FE and due to WFH, it is connected over WiFi. Once the phone gets locked due to idle timeout, the Whatsapp Web would get disconnected on my Laptop.
Resolution:
I followed the following steps
Go to Settings -> Connections -> WiFi.
Click on Settings Icon for the Current Network that you are connected on.
Expand the Advanced menu.
Change option for Metered Network as "Treat as unmetered"
This should solve your Whatsapp Web Disconnect issue.

I have the same error and I still can't solve it
Same problem but above solution didn't work for me either
A bit late, but I was having the same problem and think I found a solution.
1. Go to Settings (In Android)
2. Apps.
3. Find Whats App.
4. Usage --> Battery.
5. Select Optimized or Unrestricted (Mine was set at "Restricted")
Hope that works!
