Available WiFi networks list repopulates every single time - Google Pixel 3 XL Questions & Answers

I'm at my wits end with this problem. Hopefully someone knows what's going on.
The problem: Everytime I open the available wifi networks menu it always shows an empty list, which repopulates after 3-4 seconds. It is fairly annoying to wait for the phone to find all available networks.
Expected behavior: when opening the available wifi list, it should already be populated. At least, that's what happened on all of my previous phones, except for the Pixel 2. Is this a problem with the Pixel line? Can anyone confirm?
I think there's something wrong with my wifi settings. I've tried everything: wifi scan throttling on and off, wifi scanning on and off, turn wifi on automatically on and off, open network discovery on and off... what's going on??

I just checked mine and it took a few seconds to scan but after that if I closed it out and went back into it, all the networks were still there that it had scanned previously a few minutes ago. Tested it a few more times after that and a few new ones were mixed in without having to wait for it to scan when I opened the WiFi page. Maybe try a different kernel and see

Mine is behaving exactly as you both describe. For better or worse I think this is the intended behavior.

Thanks. Since yesterday, I've noticed mine does that as well, but I would say it's only about 20% of the time. As soon as I do other things on the phone, the wifi picker clears itself, as though the list was being kept in memory. Did you try switching to other tasks as well? The annoying thing is that my other devices always keep the list populated. My wife's S10e on Android 10 works well, I have an old OnePlus 3T and it works normally. Even my ancient Nexus 9 works as intended. Is this something exclusive to the Pixel line? Something to do with the RAM issues on the Pixel 3?

Only time I've noticed it is when I'm sleeping and the phone is idle for hours or similar scenario. I don't keep my wifi on when I'm not using it so it doesn't scan in the background. The pixel 3 series has been known to have bad memory management which I've read has been fixed with the December security update supposedly. So maybe that's something to look into.

[Q]Problems with WiFi and screen off?

Does anyone else have issues with the WiFi connection while the screen is turned off? I noticed that not a single one of my music streaming / radio apps work when the screen isn't on. It works for maybe a minute before all sound just stops. Starts just fine again once I power up the screen.
Has there been any changes done to the handling of these matters in ICS perhaps?
Pretty annoying not being able to stream music over WiFi as I think I'll hit my 5GB limit on data pretty fast if I can't use the WiFi at work for this.
So has anyone else noticed these issues?

Yeah same here. I remember this being an issue with Android 2.1 for my Desire but was fixed in custom roms. Might be the same situation here again.
I remember this being an issue with my Nexus One, don't remember if it was fixed in 2.2 or 2.3. I remember testing file transfer using SwiFTP, with the bug the file transfer would go down to double digits (kB/sec), with the bug fix it would be a few hundred kB/sec, with the screen on it would hit mB/sec or so (in any Android version).
I believe this is the official issue:
http://code.google.com/p/android/issues/detail?id=9781
With my Nexus S I'm not experiencing this bug. Sscreen on still gives me a major wifi speed boost, but screen off I get a few hundred kB/sec, which should be more than enough for any streaming app. KiloBYTES btw, not bits. I'm surprised ICS and/or Galaxy Nexus brought this problem back. Or it could be something else entirely.
Are you connected via 2.4GHz or 5GHz wifi? I would think the new 5GHz radio in the GN probably has more aggressive power saving features. Try switching to 802.11b/g (instead of 802.11n, in any frequency), see if it helps.
Have you changed your WIFI sleep policy?
On my Froyo phone, if you hit menu while in the WIFI settings (I know there is no menu in ICS) you get an option to go into advanced settings where you have the option to choose your WiFi sleep policy (When screen turns off, never when plugged in, never).
There should be a way to access that advanced settings area somewhere.. My phone is a couple hundred miles away right now and I won't see it for another week so I can't be of much further help right now. However, there "was" a setting in previous versions.
best info at the time last year was here for the N1
http://www.google.com/support/forum/p/android/thread?tid=01a47ff5b0a92d52&hl=en
7xx replies there to read, but really good info. somewhere in there, maybe around#600 the info gets good, can't remember. But shortly around this time the problem was gone/fixed.
there was a guy with an app i think it was wifi fixer, i could be wrong. that worked sometimes, but battery drain was bad. Whatever google, or CM did fixed the low power save mode issue. I'm thinking it was something at the kernel level?
edit, on second thought, there's no good reason to read all that. You won't get a fix out of it anyway. It was updated away in the end, something related to MAC addresses and build numbers and frf50 or some such.
BUT this seems like the same kind of thing going on in the power save mode.
Have you checked your advanced settings?
Wi-Fi>>(settings [bottom right])>>Advanced>>Keep Wi-Fi on during sleep...
Mine was set to always by default, so I suspect that the issue lies else where...

I would suggest that this issue is related to the individual applications you are using, rather than anything to do with Android.
I am able to stream music from Google Music via WiFi just fine when the screen is off, and I am also able to talk to someone on Skype via WiFi just fine when the screen is off.

Thanks for posting that; I was getting pretty worried and disappointed after reading this thread. I had to deal with this when I first got my Nexus One, until Google released the 2.2.1 update with a new Broadcom driver which finally fixed the issue. No streaming, no pushes, just nothing at all from wifi when the phone went to sleep. All traffic to/from the phone would just stop. It was maddening.
The Galaxy Nexus comes to Canada a week from today, and this would've been a show-stopper for me. At least it's working for you, so my day isn't ruined quite yet
Has this issue ever been nailed down? I've seen considerable discussion on it going back years. I've seen considerable speculation regarding WIFI mode and Governor. I've seem many of the bug reports marked closed.
Yet I have a GN on v4.0.4 and the moment the screen goes off - either because you turn it off or it just times out - the WIFI goes to h*ll. I've run ping and network trace from both sides and there is no doubt the WIFI stays connected, however latency goes way up and packets are lost... and with TCP connections it gets congested with retransmits. I've run with the governor set to "Performance" and there is no difference.
So, is there any consensus on what is causing this problem with current stock hardware/software?
I read that it's something that's been coded in for a while. Try using this:

Ok, to answer my own question, this is still related to the PSP issue from years ago:
code.google.com/p/android/issues/detail?id=9781
code.google.com/p/android/issues/detail?id=15549
Bottom line is that some hardware - like GN - has an additional level of PSP on WIFI. The issue was resolved by inclusion of an additional lock mode - WIFI_MODE_FULL_HIGH_PERF - some time ago. However, its up to an application to request the new lock state if it thinks it needs it. Many don't.
So, its probably not a bad idea to contact developers of the various applications and recommend they look into the new lock level in the later APIs.
Also, the "WIFI High Performance Widget" can be used to manually hold a WIFI_MODE_FULL_HIGH_PERF lock on the WIFI if you're dealing with an application that isn't doing it its self. Beware of the other "WIFI fixes" out there, none of the ones I tested were acquiring the correct lock.
Also, from an adb shell you can use "dumpsys wifi" to see who is holding what lock, for example:
Code:
Locks acquired: 5 full, 5 full high perf, 5 scan
Locks released: 4 full, 4 full high perf, 5 scan
Locks held:
WifiLock{PANDORA type=1 [email protected]}
WifiLock{HighPerformance type=3 [email protected]}
Here you can see Pandora is only holding type=1 (WIFI_MODE_FULL) and HighPerformance is holding type=3 (WIFI_MODE_FULL_HIGH_PERF). Dumping the WIFI state takes the guess work out of it.
Tried that widget, having absolutely no luck with 'in tune' and 'winamp' for radio with the galaxy nexus verizon...
as soon as the device sleeps, wifi goes to hell and buffer drops in and out every 2 seconds. Completely unusable, any recent fixes? this is totally making me think I just bought a $400 brick since this feature was very important for me.
What may be confusing about that widget is that it is a "widget". You have to locate it under "widgets" and then put it on the surface and then click it to enable it... it should be blue when on, and black when its not.

I have been trying to put the 'widget' itself (2x2 square) on the home screen but even if i hold and drag it to where I want it, it never actually appears on the screen. And of course i'm still getting crazy ping times...Does anyone else have this working on a GN (verizon - not that it should make a difference)?
I have found a few workarounds to this issue, none are great and frustrate me greatly.
1. Root and use the franco kernel. Seems people with that have no issues - since you can set? the wifi to full performance.
2. Use this wifi performance widget
3. Use an app that has properly set its own wifi settings. - Going through all the radio apps on the google market, i am finding only one app that seems to be doing this right: DI Radio - some kind of dance/techno/etc - confirmed it with ping times, they remain low on sleep.
Not one other radio app seems to have set 'proper' settings - which shows that something needs to be addressed in the os...I was having good luck with the yahoo music app, but depended on the stream (maybe some buffer more :dunno - the ping results are garbage.
EDIT: I tried installing high performance wifi again, and finally got the widget to one of the homescreens! Let me break it down for anyone else who comes across this. After install, the small 1x1 blue app box is put on your desktop and the black screen comes up with the wireless networks and a checkbox. I then went to apps->widgets and tried putting the 2x2 widget on the home screen again, and like always it clicks on like its there (and when you click home and its never there). However, this time I hit BACK instead of home after dropping the widget and it took me back to the black screen with the checkbox, then i hit home and voila its sitting there. You can click on it like you mentioned! Confirmed with ping for tune in...pings remain low.
If this continues to work, it may be a godsend. It is annoying having to have this, but far far better than not.
I had that problem also especially when i tried to download big files when the screen turn off the download speed became extremely slow, this widget solve this, i think to that moment its the easiest solution tap it when you need it tap it again when you done.
By the way i had this problems with franko kernel also and again to my opinion it is the good solution for now, until the apps developers update their apps.

If you download the SDK - you only need Android SDK Platform-tools - to a PC and use the adb shell it is easy to dump the WiFi lock state with dumpsys wifi and see exactly which app(s) are holding what locks. Completely takes all of the guessing out of who is doing what when. Judging the behavior can be subjective because there are other reasons that the WiFi can break up which can be very frustrating.

The app does work well, however I have been running into some issues as I continue to use it. It randomly decides to turn off the forced max wifi (even though its still blue and looks like its operating) or perhaps the phone is forcing the wifi issue again. It seems to happen when you are downloading, playing with some other apps? You only notice it when you sleep it and the streaming radio immediately starts having issues.
Solution is to flip back to the widget turn it off and turn it on again. It works, but is another annoyance.
I haven't yet ascertained exactly what causes it to switch off yet.

I will look into this, thank you.
---------- Post added at 06:16 PM ---------- Previous post was at 05:28 PM ----------
I used the adb shell (learned how to install all these dev tools and how to use it first ) and here is some updated info:
Tunein = type=1
Pandora = type=1
Audioaddict service (Digitally imported app I posted above previously) = type=3
google music = type=3
High performance app = type=3 (havent figured out why this likes to stop randomly)
I will update with more app info, hopefully others can also email the developers and see that it gets fixed, so we no longer have to use damn workarounds...

Yes, it definitely has an issue holding its lock, and it definitely seems related to another application taking over and also when it switches to cell and back, I can confirm that. It may be related to the OS since the widget thinks it still on when clearly the lock as been released, so it may be that the OS released the lock and the widget has no idea. I haven't taken the time to look into the details yet, and this is something we should make the developer aware of.

Yup, from what I can see it loses lock:
1. when cell switching
2. manually killing/starting wifi
3. when ANY application is downloaded/removed (ie. changes in permissions)
4. when playing with dolphin, other apps for more than a few minutes, it will kill it even though the blue stays lit. I think its as you mentioned, during general use of the phone, at some point some permissions are changed and hifi performance is tossed off its lock.
If you only are streaming music and re enter the phone to check a gmail alert or two...it seems to be fine. otherwise you need to hit the lock widget one more time before sending it to sleep with pandora/tune in playing.

[Q] Loss of BT and WiFi every day

I received a brand new Galaxy Note 4 from Sprint a few months ago to replace a problematic LG G2, but didn't activate it until last week (it sat in it's box prior to that and wasn't even turned on). At first, it worked great, but recently it has been losing Bluetooth and 2.4 GHz (I think) WiFi connectivity every day or so (usually when I wake up in the morning), and the only way to get it back is to restart the phone.
Has anyone heard of this? Or have any suggestions on troubleshooting or resolutions?
Thanks very much!
Three things to mention:
1) I did the tap & go to transfer my data from my old LG G2 (running some version of Android 4.x - I can't remember which one specifically) to my Note 4, but that was a week or so ago and the problems only started in the last few days.
2) The Note 4 came with a version of Android 4.x, but I updated it to Android Lollipop - again, this was done a week or so ago and the device seemed to work with no issues after doing it.
3) I am using the Samsung Gear 2 watch with the phone via Bluetooth but it seems all BT connectivity dies when the above issue happens (such as no ability to connect it to my car BT, etc.)
Thanks for any assistance!
Have you changed the visibility timeout to never? Then keep Wi-Fi on during sleep? For the Bluetooth problem, which I had also,I did a factory reset and haven't had as many problems since.

Thanks for the info. I haven't ever made any of those setting changes previously, which is what leads me to believe something is wrong. For Bluetooth visibility, it is set to "2 minutes", but wouldn't this just be when a device is initially connecting to my phone, and not when a device is already connected? And for WiFi, it is set to "Always" for "Keep Wi-Fi on during sleep", so this is already set per your suggestion. Basically, things used to work fine, and now every night it seems to lose BT and 2.4 GHz WiFi. Per suggestions on another forum, I did a cache partition wipe, but this doesn't seem to have helped. This morning I woke up, and the device had lost it's connection with my 2.4 GHz WiFi network (wasn't even seeing it), and had connected to my 5 GHz WiFi network, and while it still showed connected to my Samsung Gear 2 watch, I don't think BT was working since I tried to connect it to another BT device and it failed. I then restarted, and it worked fine (until tomorrow morning presumably). I'd prefer not to hard reset, especially since there's no guarantee doing so will fix the issue and it won't just re-occur, and because it'll take me a lot of time to back everything up, hard reset, and then restore data, settings, and customizations to my device.
Any other suggestions or thoughts? Thanks!
I just wanted to say that my connectivity timeout is set to two minutes as well. I use my BT everyday for my headset and my head unit in my big truck and have had no issues.

Thanks for the info! This is so frustrating - just started using this device, and already it's broken...lol! Anyone have any other good thoughts or suggestions on what I might be able to do to resolve without a hard reset? Thanks!
Any other thoughts/suggestions? I'm open to Anything at this point!!
I spoke with someone at Sprint Tech Support, and they had me turn off WiFi Power Save Mode using *#0011# (and then choosing WiFi from the three dots menu) to see if this would help resolve the above issues. It didn't, and now even after re-enabling the power save mode, things have gotten worse. Now, every time I leave a location where I'm on WiFi (such as my home), my device's WiFi never refreshes to auto reconnect to other WiFi SSID's elsewhere. So even if I leave my home and arrive at an office where I've previously saved a WiFi connection, the phone stays on 4G/LTE until I manually turn off WiFi and then turn it back on a minute or so later. And I still think the 2.4 GHz issue (above) is happening as well.
WiFi is basically useless on my phone now - anyone have any ideas at all?
Thanks!

Verizon S8+ Bugs and Issues

Hi everyone,
I have 2 Galaxy S8+ from Verizon and here are my issues:
Past issues:
One of them did not come with the Galaxy Apps store (Not the plays store), and that phone also experienced the DQA issue
Current issues:
If I turn on Fingerprint gestures, the fingerprint sensor will stop working, this was an issue I had from the day I got the phone and has continued even through the updates. Here's a thread I made about it a while ago : https://forum.xda-developers.com/galaxy-s8+/help/fingerprint-sensor-t3595614
My internal speaker has detached, or at least I think that is the issue, as sometimes when I am in a phone call and shake the phone just a little bit, it will either start making a weird buzz sound or completely cut off the sound. Shaking it again will fix it, that's why I think it's a physical issue. I haven't dropped my phone and just in case I ever do, I have a case and a screen protector on it, and neither of them (phone, case, screen protector) have any damage marks on them.
The Biggest Issue: Currently this is the most annoying bug I am experiencing is that whenever I go to lock screen and security in the setting app, it crashes the settings app. I also can't use the search function in the settings app, as it crashes the app withing a few seconds. The lock screen and security is the only menu in which I experience this, I am 99% sure this is due to me turning on Secure startup. I had it turned on a few days after I got the phone and it worked great, I had to turn it off once, about a month ago in order to get a quicker boot. After that I was experiencing issues turning it back on (meaning I turned it on, rebooted the phone and it would not work) , after some persistence, I was able to get it to work and it has worked and still works.
One thing to mention is that I had done the most recent system update, I am not sure this issue was caused by at, since the inability so search in the setting menu has happened prior to the latest update.
I have tried everything other than a full factory reset (wiping all cache, wiping apps cache, reset setting, reset network settings), which I refuse to do, It is absolutely unacceptable for me to pay this much for this phone and have so many issues with it, I have factory resetted my phone (Samsung's recommendation) in order to fix the first issue listed above, multiple times and it did not work.
At this point I really don't know what to do, Samsung support has been useless in this, I don't wish to replace my phone right now as I need it to much to even give up for one day, If anyone has any advice/fix other than factory resetting, I'll happily try it.
Thank you,
GGgamer16
Sounds like a factory reset is needed. I just tried all you mentioned with zero problems on the newest update w/ navbar options and experienced none of that. Speaker problem is most likely hardware related.

You try changing your WiFi channel? Using 5ghz or 2.5ghz? I use Wifi 100% of the time I'm home and never have any issues with disconnects.

Yeah I have tried changing channels. It didn't matter. I'm on 2.4 GHz.
I found a possible fix from another forum. I changed my wifi encryption from wpa2 AES/tkip to wpa2 tkip only last night and was rock solid after that point. I didn't have any more wifi issues... Just wanted to mention this change for other people. I usually got 5+disconnects every night. I'm gonna try just the AES option tonight and see how it acts.

Fingerprint sensor issues, and WiFi issues "Obtaining IP address"

My LG G7 is a Verizon Wireless model that is not rooted. Over the last few weeks, the fingerprint sensor has been working only part of the time. Mostly, when I hit it with the phone locked, it will do nothing. Then I push the power button to get the screen to light up, and it leaves me at the knock code screen. 95% of the time, the fingerprint sensor will work at this time (yes I know I need to use the knock code when I boot the phone, before the sensor will work). A couple of days ago, the sensor would not work at all, so I went in and deleted some stored fingerprints. When I tried to enter new ones, I instantly got a message on the screen telling me the sensor was not working and to contact a customer center.
So, I did a factory reset and set the phone up as a new phone, figuring some setting was wrong, or an app messed with things. No luck. Still a partially working fingerprint sensor. Strange thing is, I then booted into safe mode and the sensor works 100% of the time. In regular mode though I may be able to wake the phone 5 times in a row, and then for the next 10 times nothing.
A short time after these issues started, I started getting a WiFi issue in that my phone will not connect to my work's "Public_Access" WiFi. It connects up to my home WiFi, and other WiFi, but not at work anymore. My tablet connects at work, and everyone else's phone connects, but not mine. I get a "Obtaining IP Address.." message, and every once in a while it will flash the word "Saved", but no luck in connecting. Signal strength is "good" to "excellent". Link speed is normally around 144 Mbps or higher, frequency is either 2.4 or 5Ghz, and security is "None". None for proxy, and I'm DHCP. If I go to static settings, the IP and gateway look like numbers from home.
Anyone else having these issues? anyone found any workarounds?

By any chance are you using VZW Messenger?
I'm having the same issue with the fingerprint sensor. The only workaround I've found is to reboot the phone, then it will start functioning again for a little awhile. Very bizarre.
I also recently started having issues with the fingerprint scanner. Since a lot of people have this issue I'm starting to think it is software related.

Strange thing is, I then booted into safe mode and the sensor works 100% of the time. In regular mode though I may be able to wake the phone 5 times in a row, and then for the next 10 times nothing.
A short time after these issues started, I started getting a WiFi issue in that my phone will not connect to my work's "Public_Access" WiFi. It connects up to my home WiFi, and other WiFi, but not at work anymore. My tablet connects at work, and everyone else's phone connects, but not mine. I get a "Obtaining IP Address.." message, and every once in a while it will flash the word "Saved", but no luck in connecting. Signal strength is "good" to "excellent". Link speed is normally around 144 Mbps or higher, frequency is either 2.4 or 5Ghz, and security is "None". None for proxy, and I'm DHCP. If I go to static settings, the IP and gateway look like numbers from home.
Anyone else having these issues? anyone found any workarounds?

By any chance are you using VZW Messenger? It was an update to VZW Messenger that caused the issue for me. Next update resolved it.

I do have Messenger on the phone. It is NOT set as my default messaging app as I do not like it. Only reason I have it is because too many of my colleagues send me messages through it, which I can't open any way else that I know of. I'll look for an update and see if that helps. If not, I'll delete it and check again.
Thank,
Andy
Last update to Messenger I have is from April 9th. I looked for a more recent update but no luck.
Just deleted Messenger, and rebooted. After the initial need to enter the knock code, I slept the phone by tapping the power button (sorry if my terminology is off). 4 different fingers then and no joy (from the sleeping phone). If I hit the power button, the screen lights up and leaves me at what I guess is the lock screen showing recent email and calendar events. From there, I can successfully (still about 95% of the time) use the fingerprint sensor or the knock code to unlock the phone. But from a screen-off, sleeping mode, the fingerprint is still in a maybe it will work, maybe it won't situation.
If I have the same problem for about two weeks approximately install youtube vanced and yowhatsapp I do not know if it will be that but it is very annoying I hope lg update soon but I do not think I have the Indian version
Have same model and had same issues. I recently found out that I was missing 3 updates. December update started these issues. I'm now on the 10j version and so far haven't noticed the issue. But it's only been a day or so.

I am also on 10j, and the issues are still there in regards to the fingerprint sensor....although for some unknown reason, after weeks of no WiFi at work, my phone finally decided to hook up to my work WiFi yesterday afternoon, and this morning when I got into work it instantly hooked up to it again. So, hopefully the WifI issue has been rectified. I guess I should somewhat count my blessings as WiFi is more important to me than fingerprint sensor, in the big scheme of things!
There has to be a software/firmware issue going on though as the sensor seems to be most troublesome when the phone is sleeping. Once the lockscreen is on, although there are still issues, it works 95% of the time. That makes me believe it's not a hardware issue.
I have Verizon also. It may help if all of you download the latest kdz for Verizon and reflash it vs factory reset. Using the lg up method by lamemonster. I do it all the time when I cross flash kdz as well as flashing back to Verizon. Hope this helps.
My G7 EAW is the same, fingerprints flicker. However, I removed the back cover and corrected the fingerprint, and it worked normally

can you link to or specify that exact flashing method? nothing works for me, second piece of new hardware, no results.

WiFi auto connect no longer working after Android 10 Update

WiFi Auto Connect no longer working after Android 10 Update
I normally turn off my WiFi when I leave for work in the morning and it would automatically turn back on and reconnect once I pull in my garage when I come home form work.
Since updating my Pixel 3XL to Android 10 it no longer does this? I didn't change any settings and I've checked and made sure all the proper settings are correct.
Anyone else having this issue? Halp!

You don't need to turn off your wi-fi when you leave your house, or ever. Try resetting network settings under Settings>>System>>Advanced>Reset options.

I've noticed this too. It's not really a showstopper for me, but it is irritating... I wound up doing a whole clean install for 10, so it shouldn't be from any residual crud or anything like that, I have no idea what's up there...

I just love it when people tell other people what they will ever need to do with their phones.
There's multiple reasons for wanting to turn off WiFi when you're not using it - from saving battery life, to not wanting your music to drop out if you're streaming in your car and you get close enough to an Xfinity (or any other captive portal you have connected to before) hotspot and it connects, thus leaving you without a network connection until you log in, which you can't do cause you're driving.
Try turning all the settings off under wifi preferences, and toggle the rating provider, turn them back on. Mine seems to work fine.
It's the same for me. Android 9 used "Smart Wi-Fi" where it would recognize where it was, and automatically turn it back one even after manually turning it off. Android 10 dropped this feature. It was useful as I used it all the time.
