No mobile data when screen is off - N950FD - Samsung Galaxy Note 8 Questions and Answers

Hi,
I have a N950FD and I am having issues when the screen if off, there is no mobile data. I can tell by looking at my web whatsapp that it's telling me phone is not connected and has no active internet. All apps are unable to push any notifications until i start the app/.
On wifi, everything is fine though. The second my phone hops onto wifi, all notifications get pushed instantly (ex: discord, twitter, instagram, and etc), and will continue to get notifications while the screen is off.
I tried the Reset All Settings option. I made sure it is not in Power Saving mode, airplane is off, i check all apps have Allow background data usage, Data Saver is off. Not sure what else to do other than wait for Samsung tech support for further troubleshooting.

Diamond Wifi problem

Hi im having a problem can someone tell me if this is right or not.
When i have wifi turned on conencted to some point and using msn, after a while of not touching the phone the phone goes to sleep mode automatically when i press the side button to get back to the screen menu wifi shows its turned off and msn was already dissconnected the moment my phone went to sleep mode.Is this nromal?If so is there a way of fixing it.Thanks
As my first time using windows mobile not sure if its right or not.
Wifi will not remain active once the phone enters standby mode. If you switch the phone on again, wifi should also automatically wake up, but needs to restore the connection to the wireless network from scratch.
I see thanks.
Is this different for bluetooth even when its in stayby mode it seem to work.
Thanks
That's correct. Bluetooth remains active in standby and therefore a major battery sucker.
I see thanks everyone. So pretty much impossible to have MSN on the whole time unless i set my phone so that it will not go to sleep mode. Hence msn beceoms a big battery sucker as wifi will be on for a long time?
Thanks
Is it really impossible to tell WM to leave Wifi switched on when my Diamond goes to sleep mode?
Has somebody a solution for this?
Yeah I have a similar problem with emails... I'm trying to get emails over wifi/wireless lan, auto send and rec every 15 minutes but the device enters standby before this time... Done a ping to the device and as soon as it enters sleep mode it kill the connection... I would think that if there is an active app (like MSN or EMail) that wants to download data it would reconnect to any setup wlans or stay connected when using a service like msn... Is there any reg hack for this..?
My next question is when the back light dimms (not enter stand by) is it possible to set up keylock? i.e. disable the touch screen/HW keys, then I could standby the device after 30-45 mins (see how the battery goes on that one..!)...

Edit: I did a bit of digging around the web found this tool called PocketToolman - http://freewareppc.com/utilities/pockettoolman.shtml - Looks like it has an option to enable wifi in standby mode Seems to work anyone else want to give it a test to see if it works... I'll see if I can find a reg key for this tomorrow, unless anyone knows of one already? Looks like the standby kills the CPU so WiFi packets can be processed etc..? But Win Mobile 6 Pro has an "unattended mode", that should allow wifi to work and emails to s&r and MSN to stay connected... For eg this app calls unattended mode to keep wifi active... http://www.pda-ppc.com/download/communication/content/WMWifiRouter.html
EDIT 2:
I've been able to find the following keys that should work with the wifi...
make sure the 98C5250D-C29A-4985-AE5F-AFE5367E5006 class mataches wifi adapter
Disabled Enabled
HKLM\System\CurrentControlSet\Control\Power\State\Suspend\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
HKLM\System\CurrentControlSet\Control\Power\State\Resuming\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
HKLM\System\CurrentControlSet\Control\Power\State\Unattended\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
Now I'm assuming that HKLM\System\CurrentControlSet\Control\Power\State\Suspend\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default will keep the wifi connected in standby mode... I'm going to test, can others also test to confirm?
DWORD Dec values have states 0-4, 0 being full power 4 being off... Just to test it, use vaulue of 1... Need a soft reset... It may be worth changing the vaules to 2 or 3 to see if WiFi still remains connected but what the battery drain is like...
Found another app that may also work - http://freewareppc.com/communication/wifiprofiles.shtml
Creds to http://209.85.175.104/search?q=cach...wifi+unattended+mode&hl=en&ct=clnk&cd=7&gl=au for key locations
Someone else test these and let me know what results you get/what power settings you use...
Given how quickly my phone battery drops with WiFi enabled I doubt you'd get more than 3-4 hours out of it if WiFi was enabled in standby mode.
When you want to use MSN over wifi set the following reg keys to dec value of 2:
HKLM\System\CurrentControlSet\Control\Power\State\ Suspend\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
HKLM\System\CurrentControlSet\Control\Power\State\ Resuming\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
HKLM\System\CurrentControlSet\Control\Power\State\ Unattended\{98C5250D-C29A-4985-AE5F-AFE5367E5006}\Default
Power state of 3 doesnt seem to work..? Ideas?
Did some testing using each value as 2 (low power)... For me it drained about 35% of the battery in 4 hours... So you should get a full day (10hrs) out of it before you get to 10% or so...
Be worth making an app that allows you to toggle this...
I know this doesn't really apply to MSN (which needs always-on wifi), but for emails at least maybe there could be a way for the phone to activate wifi instead of the data connection when it wakes up every N minutes to check for new email. And then maybe after a timeout period it could activate the data connection (i.e. if there is no trusted wireless network available) to get the emails. Anyone heard of such a thing?
Also, why does wifi drain the battery so quickly in standby mode but the data connection does not?
Bumping this. Does anyone have any ideas? I might cross-post this in the Touch Pro forum if no one has any thoughts here.
This may help:

Honestly no expert on this, however if you install Advanced Config, under Menu/More Settings/Connections there's an option "Enable Wi-Fi on standby mode" I guess if you tick that you mught have your solution...
I personally haven't tried it.
Yep, just checked it myself and it seems to be do the trick...!
Obviously what sucks there is that you'll need to manually turn your WiFi on and off or otherwise you miht get some serious battery drain...

Program to mute just email notification during night?

I receive emails every 30 minutes on my Fuze. I would like to keep my phone volume on loud during the night (just incase I receive a call), but somehow mute or stop just the emails from coming in. Is there any program that can do this? thanks in advance
start/settings/sound&notifacations , scroll down to email , and uncheck what you would like to uncheck .
or download g-profile from ageye , look it up on google . it works quite well
Another solution: I use Phone Weaver (SBSH) - SPB makes equivalent Phone Suite, but I like Weaver better...
My setup = My phone not only goes to vibrate mode whenever certain categorized appts happen in my calendar (meetings/Clients/gigs), but every night at midnight it turns to silent or vibrate, the push mail shuts off, bluetooth shuts off if its on. At 5 am, wifi turns on and SPB backup kicks in if AC plugged in and wirelessly backs up my whole phone to my desktop every day, then turns wifi off. Then in the morning, resume pushmail and volume full.
I rarely ever have to touch my volume settings unless im going to a movie or dinner or something. I never have to think about backing up/losing my backups on a lost/stolen storage card/phone.
I just checked G-Profile too cause I've never looked at it. It seems like it does mostly the same things as P Weaver. try all the trial versions, see what you like.
If you are using active sync, you can set the peak vs off-peak time so that off-peak is when you don't want to recieve email. Then set off-peak to sync Manualy.
use mortscript to set it up.
http://forum.ppcgeeks.com/showthread.php?t=65663
you can also simply turn off the push feature using comm manager. What I did was modify te options in comm manager using the app called Advanced Config. I removed the 3G control from comm manager and added the control for Push Email. At night, I simply turn off the push email and that way the phone still stays on to receive calls but email is no longer pushed.

A few remaining issues... Need Help

After running Android for a couple of weeks on NAND, I've noticed a common problem among Myn's and Plemen's Android builds using the latest dzo's nbh files. I don't know if it is related to what I'm doing but the auto sync functionality of google (including gmail, calendar, and contacts) is very flaky and I get an odd reboot problem.
Since I usually use the phone as my primary wake up alarm in the morning, I never turn it off. Instead, before i go to bed, I put the phone into airplane mode and plug it in to charge. What I've noticed in the two weeks is that more often than not, the phone reboots itself sometime during the night. I noticed this because several times, the single plus double vibrate on startup wakes me up. Other times, I wake up and the screen is on (I've set it to never sleep when plugged in). It's not all that major as long as the alarm rings at the proper time.
Then, as I get ready to go to work, I turn airplane mode off. When I get to work I see that the phone says I have no email. I thought that was odd because I usually have a bunch by 9am. So I logged into gmail on the computer to find that I have 10 unread emails that all arrived while on my way to work (between 8:30am and 9am). So I went into the data sync options to check when it was last synced and it says 8:05am (the time I turned airplane mode off). So the next thing I did was send a test email to my gmail account. No notification after 2 minutes. So I decided to reboot the phone. After it got to the main screen I could see the sync icon on the notification bar and about 30 seconds later, all 10 emails plus my test email got to the phone.
I'm not sure what is causing this problem, but I have a feeling it has to do with airplane mode.
I'll do some more testing to see if I can come up with a consistent way of reproducing this problem.
Update...
I've just done a quick test and need some confirmation from others that this problem exists:
1. Turn airplane mode on.
2. Reset the phone by pressing stylus into reset hole.
3. Wait for it to boot up.
4. Turn airplane mode off.
At this point, I went to check the last sync time in the data sync settings. It should say a time close to when you booted up.
5. Now send a test email from your computer to your gmail account.
Your phone should never notify you of the new email.
6. Now reboot phone again using the stylus method and wait for phone to boot. Your emails should arrive on the phone automatically.
7. Now send another test email from your computer to your gmail account. You should be notified within a minute.

[Q] Wifi/3G not connected whilst phone is in 'sleep'

Okay. I noticed today that when pressed the power button to wake my phone from sleep the wifi or 3g (depending on where i was and what I was connected to, ie home or away) icon was not showing and thus indicating that it wasn't connected. Hmm, I thought it was odd, maybe it was a display error. But I then noticed that my emails and gmails all came through a few seconds after I unlocked the phone (and the connection icon appeared) and that they had all been sent whilst the phone was asleep. So, it seems to me that the phone is disconnecting from any data source when it goes into sleep mode. Now, I am right in thinking that the whole point of push notifications or setting your email to sync every 5 minutes is that the phone will remain connected even whilst asleep, and then wake up (briefly even) when it picks up an email?
I had no power saver on, no smart sync, wifi set to never sleep. Is this normal? It's pretty important that I get my emails as and when they sent to me. Any advice would be great. I am wondering if it's a bug, and whether I need to take to the phone back to exchange for another one?

you're sure power saver in the top menu wasn't on? because that's what it does, turns off wifi and data when the screen is off for an expended period.
maybe cycle it on and off a couple of times and see if the problem persists...

No, isn't normal.
So, can you upgrade to the latest firmware and, maybe, do a full wipe?
Did you install some app for battery?
And check that your power saver isn't on...
Check under power, setting that sleep mode is off. That on by default on mine. It turns data off after extended screen of time and doesn't require the power save to be activated.

Hmm, no additional battery apps, power saving toggled and definitely off (I purposefully turned it off because of it's data management policy), and sleep mode set to off.
So, I'm right in thinking that you/others actually get notifications then? and wifi/3g is working fine? Looks like it's a return and hope that the next one works (I only got the phone 7days ago). My software update says no updates available, though this is likely to be EE fault. If I can get the shop to exchange I might just do that. Ho hum, another 3 hours setting the thing up again then...
It seems to be a Wifi switching itself off problem...

So, a quick update in case anyone else is having this problem.
I reset the phone to see if it would make a difference and it kind of has. Now I have noticed that if I am using mobile data it's fine. Things are pushed, notifications come through. But if I use Wifi it's a different matter.
it seems that with Wifi on and connected then it works for around 15 minutes when the phone is sleeping (I have done a few tests). After this it seems to shut wifi down and hence no notifications. So it would seem to me that although Power Saving is set to OFF, and Sleep mode (ie no data in sleep) is set to OFF, the phone is still disconnecting from WIfi regardless of the settings. Which is a bit frustrating as I don't want to be connected to the mobile network all the time, especially at home, but still want to know if I receive emails.
Anyone else experienced this Wifi switching itself off issue (and then switching itself on as soon as you manually wake the phone?)? I have to decide whether to return the phone for a replacement or not. If this is a wide ranging issue it might not be worth it - though I'd have thought a simply thing, like keeping wifi on at all times wouldn't be hard to make sure it worked.
there are a few apps available on the play store such as "keep wifi alive" which might do the trick.

Okay, now I feel a bit of Doughnut! I think I've found out what was causing this. So, even though I had Power Saver OFF, Smartsync OFF, Sleep Mode (disconnect data whilst sleep) OFF, I hadn't had a proper look in the Wifi settings, and under Advanced I found:
Advanced>Keep Wifi on during Sleep. This hadn't been set to Always and was set to 'Only when plugged in'. So, changed to 'Always' and now it seems to work (and that would explain why I got emails through the night when charging).
So, apart from feeling a little red-faced for not exploring every single menu available, I am happy it (seems) sorted. If anyone has wifi dropping whilst phone is sleeping it seems there are four steps:
SmartSync = OFF [in Mail app]
Power Saver = OFF [in status bar and Power Settings]
Sleep Mode = OFF [in Power Settings]
Keep Wifi on during Sleep = Always [in Wifi>Advanced Settings]
Hopefully this'll help anyone else who has been having a bit of prolonged blond moment with the phone settings. {retreats to corner}

I have similar problem. Even when I have everything OFF as you suggest, I get disconnected a second after screen goes off. When I turn phone back on, I can see that wifi is on, but all aps are off and wont connect again. I have to turn wifi off and on and applications like skype go again online. I have this problem at home and also at work on corporate network. I have even tried apps that should keep wifi on, but with no change.
Interesting is that after the phone goes to sleep mode, I can see that speed of wifi is changing on phone. The phone actualy stays connected to wifi, but doesn't send or receive data.
The router at home is TP-Link 1043ND with DD-WRT (flashed to last firmware to see if it fixes this problem). I'm not sure what brand and type are corporate APs, but could be some cisco or similar.
Any advice what else I could try?

Freezing and Loss of cellular network signal

Hello.
SM-9500, 128GB, Snapdragon.
Three bugs:
1. Whatsapp Web constantly loses the phone. It helps if I go to the app on your phone. At the same time, the Internet is always available, with Telegram there is no problem in this regard. On Wi-Fi everything ok.
2. Communication (cellular network signal) is lost periodically. The phone shows the full scale of reception of the cellular network, the display is unlocked, but at the same time it is impossible to get call. After a while, sms come up about missed calls. Even Sim has changed - does not help.
3. The saddest thing. The phone freezing periodically. Once or twice a week. The first two times were at night, when standing on the charge. Once on the display, the Olways On Display picture was displayed (but did not move as in normal mode) and the charging indicator was on.
The second time the display was completely turned off, but the notification light was flashing.
For the third time, both the screen and the indicator were turned off and the phone was not on charge.
In all three cases, the phone did not react to any buttons, only the power + vol download buttons helped (it's strange that it's not just the power button).
Did anyone have something similar?
I do not want to do the reset and even more to carry in the service (it's not clear how to repeat last bug).
P.S. Sorry for my English.
My wife's Note 8 periodically loses LTE signal, and sticks to 3G. USA T Mobile version.

I understood the problem - it's switching the phone to 4G + mode.
when the phone is in standby mode, it is switched to 4G.
At the same time, it is impossible to receive a call or SMS, whatsapp does not work.
If I turn on the screen and open, for example, the browser, then the switch back to 4G + and the problem disappears (whatsapp works, calls and sms arrive).
This is confirmed by the fact that if I turn on the network mode only 3G / 2G, then there is no problem.
How can I turn off the transition to 4G + / 4G?
Or maybe I can somehow get the phone to correctly switch between 4G and 4G +?
