Question WiFi seems to be disconnecting overnight - Samsung Galaxy S22

I thought this was an issue with my ISP or WiFi, but now I think it's an issue with the phone.
Many nights a week, I notice that my podcast feeds haven't updated as scheduled. This worked most of the time on my previous phone (S10). The logging (or lack of it) implies WiFi wasn't on at the time and so it didn't try to update.
The other thing is that I noticed when I woke up the phone screen, a bunch of notifications and their sounds from different apps happened in succession. These weren't scheduled, as it happened at some random time like 7:17am. My Do Not Disturb setting is set for 10:30pm to 6:30am.
At times (with both phones) I've noticed the WiFi in the morning just isn't connected. Sometimes I had to tap the SSID to make it connect, other times I had to disconnect and reconnect, other times I had to disable WiFi and re-enable. These instances may have been a mix of the phone, the router, and the ISP, but I can't tell, and they're not often.
I think most likely it's a mix of my ISP being troublesome and making my router freak out (that has happened a lot during the day), and Samsung's software being over-vigilant, maybe in trying to optimize connection or battery or something.
Regardless, I'm trying to figure out what I can look at or do on the S22 to find out what's wrong (logging or tracking somewhere?) or troubleshoot it or fix it. There could just be some odd one-off setting somewhere, but I've gone through a lot and it's a rabbit hole and nothing I've changed yet seems to get at least my podcasts to update overnight. The notifications only happening when I turn the screen on hasn't happened much, and it's a minor issue anyway (since I don't often wake up after 7).

[SOLVED] Sleeping phone won't connect wifi when enabled by Tasker

Hi guys,
I have no data plan, and I use wifi at home. I have a Tasker script that turns wifi on when at home, but turns it off overnight to save battery and avoid cooking my delicate brains. At 6.30am, Tasker switches on wifi and normally the phone would then fetch email etc. whilst sitting on my bedside table, so when I wake up later and check the phone, everything is there waiting.
Recently, this has stopped working. Tasker is switching on wifi as normal, but wifi will not connect whilst the phone is asleep. If I wake the phone, wifi still won't connect however many times I wake it until I unlock the phone. Wifi then connects immediately. I have no problems holding a wifi connection at any other time of the day whilst the phone is asleep, and my wifi sleep policy is set to "never". It is only first thing in the morning I have this issue, so I assume it is related to Tasker switching wifi on whilst the phone is sleeping.
Anyone have any idea what could cause this? I changed from CM7.0.3 to CM7.1.0 recently, but I can't be sure if that coincided with my problems starting.
Thanks.
UPDATE:
I solved my own mystery in the end. I forgot to mention that in Tasker, as well as checking the time I am also doing a "cell near" check. When I remove that check everything work correctly. Tasker help mentions that cell location updates sometimes don't work reliably when the phone is sleeping, and that this is a bug in Android. I can only assume that updating from CM7.0.3 to CM7.1.0 introduced that bug for me.

wifi goes sleep even setting policy to "Always On"

I have set the Wifi policy to "Always on".
Many times (but not every time) when my One X goes into sleep mode, all data connections don't work. I notice it because I feel so strange there is no notification from Whatsapp and Line as usual. So, I press the power button and see no data connection at all. After a few second, 3G data connection appears but no wifi. Wifi then replaces 3G a few second later.
It usually happens and I feel so annoyed as I lost communication with my colleagues when One X is sleeping.
Is there somewhere in "Setting" that can override the "Always on" in Wifi policy? If I miss it, please let me know.
I feel very disappionted with my One X as it contains a lot of bugs.

It's happening to me too, it's very frustrating because when turned on it show as connected while it's false.. and i'm unable to browse/etc without re enabling wifi manually.
Same issue on the One S. This is most likely a driver related problem or something. I think the next firmware update should fix this, but if anyone of you can provide a hotfix or something I wouldn't be sad
Getting the exact same problem.
I have not noticed this so far.
same problem with wifi....and in the nights my Data also gets switched off after sometime of inactivity...couldnt find any setting related to that....do any of you know any hidden setting for it?
Yeah it happening to me as well. It could be kernel related.
Same Here
Mine is opposite, I want it to sleep on screen off but it keeps reverting to always on. Quite frustrating as it is the major cause of my battery loss
Sent from my HTC One X using XDA
Mine uses less battery with wifi on then normal 3g/4g

I cant connect to my home wifi, it show connected then disconnect immediate
it no usaable now in my house
I just noticed this, too. Really annoying when you suddenly stop getting any notifications for E-Mails etc.
This is also not fixed in 1.28 :/.
I seem to only have this during the night hours, though. Like there is some sort of "Quiet Hours"-function but they forgot to put it in the settings >_<
I think this is the special Sleep Mode kicking in, and the WiFi Always-On is overridden by it.
When I turn the screen off, I can still ping my One X over the network. However, after some time (maybe 5-10 mins) it no longer responds and has dropped its WiFi connection.
The Always-On WiFi option has only ever applied to when the screen is off. The sleep mode thing is new and not related to android itself - an HTC hardware thing by the look of it.
Maybe it's fixable in the driver software, but I believe the "WiFi always on" function is behaving correctly - it's the new sleep state that is breaking it.
I could be wrong, but that's what it looks like.
If someone has the time, try setting up a PC to continuously ping the One X and see if it keeps it from going in to sleep mode.

Hello Dave,
Your analysis is quite impressive,
I also started dealing with this from "Special Sleep Mode" perspective.
I have got the FOTA, find data in my signature, and still suffering from the same issue.
To summarize my findings let me brief it:
When I first got the update, the problem seemed to be solved
I kept connected to my home WiFi router for several hours and got notifications from Whatsapp and Twitter
I thought the problem was solved and the bug was fixed, as I kept seeing my OneX on the WiFi Client on my router's managing interface on my PC
I shut down my phone, WiFi was on, and turn it back on
WiFi kicked in and connected with no problems,
An hour after, I sensed something wasn't good, notifications were silenced
I unlocked my phone and checked the status bar to find there were no DATA connections at all, nothing, no WIFi no Mobile Data, the usual bug
Now I started to think,
I Have got this problem after a full shut down, and at a battery below 15%
One thing to add,
I turned my phone off with WiFi enabled and when turned it on WiFi kicked in.
Now I am monitoring on the following basis.
I clicked all WiFi hot spots previously saved on my OneX and chose to "FORGET"
Connected to my preferred hotspot
Monitoring the WIFI, with battery over 15%, seems to be very healthy, more than an hour on sleep mode, and WiFi is on, uninterrupted and VERY CONNECTED
I will keep monitoring the behaviour till battery fall under 15% and will report back
I'll make sure to turn off WiFi before shutting down my phone if I have to, this is to eleminate the other variable and keep concentarting on one variable "Battery percentage"
A point to add:
On my previous Gingerbread SensationXE, there was an option on Settings> Battery to control phone's behavior and stop background sync and other activities when battery fall below a pre-defined percentage.
Default was 15%
I can't find this option on my One X, IceCream Sandwich
That's why I started to analyse the problem from the perspective of "Special Sleep Mode - Below 15%" bahaviour.
I will report back as soon as I have results.
Thank you
Update:
Started to experience same issue when battery falls below 50%.
All DATA gone down, no WiFI and no Mobile Data.
Charged my phone to 73%, "Forget" all WiFi network.
WiFi off
Monitoring Mobile Data only.
Mobile data gone down after 30 minutes sleep mode, 73% battery
Connecting to WiFi, and started monitoring WiFi
WiFi + Mobile Data gone down after 30 minutes.
Power down phone, and then on, 73% Battery, WiFi off
Monitoring Mobile Data only.
Failed, and disconnected
Failure
I've done a Factory Reset !!!
Update:
No problems on WiFi, nor Mobile data whatsoever for the whole day until battery falls below 10% !!!
WiFi disconnected after exactly 15 minutes, Mobile data kicks in, then disconnected as well !!!
I turn on the screen after 20 minutes to find NO DATA CONNECTION of any kind.
Mobile data kicks in, WiFi replaces mobile data, and start receiving all data dependent notifications!!!
I have the same problem, wifi is turned off sometimes when screen is locked.

Hello Pabson,
Thanks for sharing.
Would you provide more information about your phone's software number, your location (Region, not specific).
Thanks again.
Same here, tried several roms and the same happens with every ROM out there. What is more, I cannot connect to WIFI at work (WPA PSK) but I can connect perfectly to my home WIFI network.
Hopefully this is not a hardware fault and will be fixed.

If it happens on every single rom you you installed, then apparently this is a hardware fault.
What "Base" do the Roms, you installed, created on?!
I mean based on what version of RUU?
same problem here.
I mis the "power saving mode" options like in android 2.3
It might idd have something to do with power savings mode kicking in.

Frequent disconnects only on home wifi

Usually I can resolve my own issues, but this time I need some help.
My 360 disconnects from my phone often (about 20 times a day). Sometimes it will reconnect immediately, sometimes I have to toggle bluetooth, sometimes I have to reboot both phone and watch.
On one occasion, my phone forgot the watch all by itself, like it wasn't even there. I had to factory reset the watch in order to reconnect.
I've tested thoroughly and can confirm this is only happening while my phone is connected to my home wifi. While on data or other wifi networks (both 2.4 and 5 ghz bands), the issue is non-existent.
My phone (Moto X 2014) is running 5.1 stock and rooted. I greenify Facebook only. I use Tasker but do not have any wifi-specific profiles set.
The watch is running 5.1.1 and I'm using the latest Android Wear. I tried rolling back a few versions but no change.
My router is running the latest firmware (Verizon router provided with Fios), and I've tried broadcasting in different channels.
Kind of at my wits end, here. I would appreciate any suggestions. Thanks!
Well, it happened again last night - out of nowhere I received a pairing request from my watch. The phone had just forgotten it, and I wasn't able to re-pair without performing a reset of the watch.
Steps taken since then:
1. Set wifi to channel 1
2. Set wifi to 802.11/n
3. Uninstalled Wear Mini Launcher (provides notification when phone and watch disconnect... I suspect it might be causing issues)
I've been at work and connected to wifi for 2 hours, no problems. At home, I'd have disconnected twice by now.
Argh!
Hi
Did you sort this issue?
I've noticed it on my Moto 360/ Moto X 2014 as well.
When I connect both wifi and bluetooth and then disable Bluetooth my phone complains that Android Wear has disconnected and to tap the alert to reconnect, which I do but I'm not sure if it does anything.
Then I've noticed my watch will drop wifi connection every now and then but after a bit of messing around in the settings I found an option under Wifi settings/ Advanced called Power Save which I've adjusted to the longest time possible (180 minutes), it was previously set to 30 minutes and I'm guessing the watch was disconnecting from my Wifi network when it hit this.
I've only just done this though so I don't know if it'll solve the frequent disconnect issues, however i'll still have to reconnect the Watch after 180 minutes.

Phone loses certain settings or apps if the battery dies suddenly

I have searched as much as I can, but can't find any info on this. It has happened on both mine and my wife's M8, but only after updating to Marshmallow. If the phone dies suddenly without being able to shut down fully most of the time it will lose certain settings, like sounds, data and Wi-Fi turned off, saved Wi-Fi networks gone, etc. If it happens while starting up it has lost whole apps, all contacts; mostly acting like a first boot but some installed apps, settings, call history, text messages, etc did remain. Any ideas?

I spend the same, and also turns off me having 20 % battery....google traslate, sorry.
I get the exact same issue, but no idea why it happens :/
Sent from my HTC One_M8 using Tapatalk
It's a glitch with HTC's Marshmallow version. It happens on stock as well as custom ROMs. Nothing to do but wait for an update from them, or always make sure your battery stays charged. It happens to me at 6%
Same Problem but phone dies at 20%-30%

I am having the same problem, heaps of settings change, including default keyboard, messaging app quick settings wifi etc
if my phone was dying at 5%i could deal with it but it is dying anywhere between 20 and 30% and often catches my unawares.
An update to fix this would be great.
Yup, I have the same problem only I don't lose saved wifi networks but I get signed out of every single app. I also get a google play services error which requires me to clear the apps data.
Snap!
I have been having these problems for the past 4 months (running Lollipop)
I thought that the Wifi passwords issue and app logouts was due to low system memory. (battery would die around 15%)
Since doing a factory reset and 2 weekends ago, the battery dies around 25% and I still experience app log outs etc.
My device is close to the 24month warranty limit and I need a fix urgently.
I also have Bluetooth call random clipping happening both on lollipop and Marshmallow.
This is killing me. Any fixes yet?
Lately it's been losing home screen icons and a couple settings even when I manually shut the phone down. Ironically yesterday when it died suddenly some previously missing icons I had yet to restore reappeared.
please!! any Fix ???
Any fix??? My phone does this too, and its becoming more often than a weekly thing now
A few times now manually shutting the phone down before the battery dies has led to all Google related icons (Chrome, YouTube, Play Music, etc.) being removed from my home screens and having to manually re-add them. When the battery dies it's a roll of the dice what, if anything, will be changed/lost.
In addition to almost everything already said RE: most customization is lost, apps and widgets disappear on restart, etc. I've noticed that all of the (mostly AT&T) apps that I disabled are enabled and updated when the phone comes back on! This is so annoying and is my first major problem with this phone! It's taking time to have to redo all my settings each time the phone dies!
Same problem here very annoying especially as I have to phone bank to reset my mobile banking app as it screws the settings in this. #leaveitoncharge
Yesterday mine died at 30%, and upon restarting it went through the "Optimizing Applications 1 of 261" then proceeded to come up with a warning that the phone had an internal error and might be unstable until doing a factory reset. After clearing the warning it was stuck in a "Sense Home has stopped working" loop until I could get into Settings and clear the data for Sense Home. This allowed me to at least make sure things were backed up before doing a factory reset, but more than half of my contacts were missing as well as many text, call history, etc. A similar thing happened with the wife's M8 last week and had to factory reset hers then too.
I had this problem and had my battery and main board replaced in the final month before 24 m warranty ran out.
Do a battery test *#*#3424#*#*
Then hit more, and select battery test.
Battery has to be 100% to complete teat which takes an hour. Do this when you don't need it.
My test would often show 91-94% but I had one that said 71% which I saved a screen shot.
Since the battery and main board replacement it's still my favourite phone.
solve the problem of battery and loss of settings , change the battery of my htc, now everything is fine , 3 days that the battery is discharged properly , I hope this information will help someone.
Not positive I've lost settings, though I'm fairly certain I have. I have lost app permissions many times. And my phone seems to die around 30% and won't let me boot unless I am plugged into charger. I was recently forced into a factory reset due to a message that popped up just like a somebody else a few posts back. This is a recently replaced phone (VZW replaced it as the prior had battery problems). The prior one did not do this. I hope HTC get's their act together and fixes the issue. Highly annoying.
Ive been having this issue since the beginning of the year and now it seems to happen every few days. I pretty much don't have a choice but to buy a new phone at this point, which sucks because I love my m8.
This is exactly the same issue I've been having. I'm at my wits end with having to re-do all of my settings and apps daily, and sometimes (randomly!) it won't hang onto a charge for more than a few hours even if I'm barely using it. I basically have to leave it on a charger all the time to keep it from shutting down and losing all my settings! I used to love my M8, but for the first time ever I'm considering swapping to a Samsung just to get away from these issues. I've had this phone for a little over two years and these problems only just started around March 2016 - but they've been an absolute constant since then, and only getting worse.

delayed notifications on Pixel 3 XL

Got my pixel a few days ago. Not receiving notifications in time drives me nuts. So usually gmail notifications appear on screen as soon as I unlock and wait or after about 15-30 minutes after I received an email. Sometimes longer for whatsapp No battery saver, no adaptive battery, optimizations are off for gmail. Also tried all permutations of those settings. Tried factory reset and Q up and downgrade. Nothing seems to work. Happens on wifi and cellular. Devices isn't rooted.

Since you are fairly new here in terms of posts, why not update your profile with at least your location and carrier. We don't need your exact GPS coordinates, but knowing what city/country you live in and which carrier you are using can be very helpful in diagnosing your problem. Others in your area may also chime in with their experiences if they see you are close by. If you are on an MVNO, then state exactly which one. To start with, how many APN's do you have for your carrier and have you tested any other than the default? Verify your APN settings with your carrier's web site, and fill in any that are blank or wrong. Was your SIM from your last phone, or did you get a new SIM from your carrier provisioned for your Pixel? You should not have to tweak your phone at all for the issues you are describing. Just some thoughts. Cheers.

I have the same issues. I just ordered mine from Google, unlocked.
Sim from Sprint, updated PRL. Doesn't matter.
Sometimes I don't get notifications from my "battery charged" app.
It is frustrating. I don't know the fix, and I haven't mentioned it here either.
What seems to work so far is disabling deep/light idle via adb:
$ adb shell dumpsys deviceidle disable
Deep idle mode disabled
Light idle mode disabled

This will be lost on reboot
scrap that, it's not working either way. Don't know what to do, it's unusable that way. Kinda need fast notifications for business
I have the same problem, but, only with certain apps. I'm on Verizon in St Louis, USA. I'm currently on Q beta, but, this happened on Pie at least since the start of this year.
Messages does this the worst. I'll get the message on the web app sometimes a couple minutes before it pops up on my phone. A REALLY funny one, when connected to my SUV via Bluetooth, a message will popup on its screen several seconds, sometimes more before it does on my phone. So, to me it seems like the phone is getting them right away, but doesn't send the notification immediately?
Now, Outlook on my phone I get them before they show on my work computer. So, thankfully I'm not getting delayed work emails, that could be bad considering I'm a sys admin.
I've noticed with some others, like Facebook or whatever, that if I wake up my phone, unlock it, or another notification comes in, all of a sudden I'll get some for those if there are any. In checking FB it's definitely a late notification.
I just turned off adaptive battery yesterday for other reasons, that hasn't helped. I wonder if it's one of the battery settings though that are somehow affecting it. Like the optimization for example. I don't know. It's REALLY annoying though. This plus the Bluetooth problems that Google can't seem to fix (but no other phone that I know about has these problems), I'm really starting to get pushed away here. If it weren't for day one updates, the camera, and things like that, I'd consider jumping ship...
If anyone figures this out, let me know! I'll keep digging too.

Yeah... that was the first thing I've tried. Haven't found any solution still. Basically gmail notifications don't work. Old mails will stay as unread for half-an hour and vice versa. Pretty useless

I noticed this for the first week after a clean flash then went back to normal
Might have something to do with the new battery management
So, I've been paying more attention to this, and, I've noticed something. Every time a notification doesn't come through, even though it pops up on my watch or my car, the tap to wake doesn't work. I wonder if the screen just isn't waking up for some reason? I'm not sure how that's controlled, so I don't know how one would fix it though.
Just wondering if anyone has figured this out. It is beyond ridiculous to have to wake up my phone in order for for a notification to come though. I am noticing this mostly with Gvoice and Gmail. My most frequently used and important apps. Connected to wifi 99% of the time as coverage is terrible in my area. All battery optimization is turned off. Also, it is intermittent. Most times things come through fine. For example. I woke up in the middle of the night and looked at my phone and I Gvoice message went off as soon as I woke it up. In this case the message was coincidentally sent right then, but that is the same behavior I have been experiencing when a message is delayed. Phone and watch are quiet, wake phone, suddenly my watch and phone go off with one or more notifications from one or more apps.
The one thing I have noticed is that push notifications get effed up for certain apps and I have to turn off app notifications, fully close app/clear cache, re-enable notifications and turn the app back on/reboot.
