Ever since the very last update to NG5 I have had issues with bluetooth connectivity. More specifically any and all bluetooth devices I connect (full charged batteries)) have scratchy, choppy, and intermittent audio. I for the life of me cannot figure out why nor how to fix it. I would really like some assistance.
So basic details.
Device: SPH-l720t
Stock Rom: NG5
Wifi power saving mode disabled through dialer menu
Normal Wifi options selected
Wifi Calling enabled (needed because of crap signal in house)
Things I've tried:
Re-provisioning through dialer menu
Removal / reset / re-connection of bluetooth devices

Does this only happen when you are using WiFi calling? Unfortunately WiFi and Bluetooth frequencies are fairly close to one another (both are in 2.4 Ghz range) and can and do interfere with each other. You could very well get interference when using both at the same time. The WiFi is going to have activity when you are on a call, and so is the bluetooth - and they're both going to be active at exactly the same time - increasing the chances of interference. The only thing I can think to suggest is to change the channel that your router is using and see if that helps.
If it's happening all the time (even when not using WiFi calling), then maybe try deleting and re-pairing your bluetooth devices.

My S4 keeps reconnecting to my wifi for some reason. I get the toast notification saying "Connected to <SSID>" that will sometimes pop up every 5-30 seconds, but it never goes more than 30 minutes without doing it. My router is an Asus RT-AC66U. I've tried forcing 2.4Ghz only, 5Ghz only, changing the preamble (short, long, auto), changing the channel (manually specifying each channel, and also tried auto), and even manually assigning an IP address on the phone. None of these things help.
I have "check for internet service" under the advanced wifi options disabled, and also have it set to keep wifi on during sleep.
The phone shows Very Good signal quality. Using wifi analyzer shows a signal strength of between -45 to -68 db, depending on what room I'm in, so that's definitely not the issue. It even does it sitting in the same room as the router. No other devices have an issue, including my roommate's S3.
I can fix it by turning off wifi power save mode (*#0011#), but then my phone heats up quite a bit whenever I'm using it, and my battery drains at 10%/hour even when I'm not connected to wifi. So that's not really a solution.
Is there any other fix for this? It's a bit ridiculous. I'll load a webpage and it'll interrupt halfway through when it re-connects to wifi. Since it keeps reconnecting to wifi, it causes all the phone's connections to be re-initiated, and also seems to trigger Google Services to update the phone's location. This results in Google Services (NetworkLocationLocator) holding a wakelock for 1/3 of the time.
So it seems the problem was IPv6, specifically IPv6 that autoconfigures. All the wifi networks I typically use are dual stack IPv4/IPv6. What I'm guessing happens is that the phone doesn't wake up for some of the IPv6 broadcasts, and then the phone reconnects to fix this once it realizes it's out of sync. Turning off power save mode means it gets all these packets and doesn't have to reconnect.
So I fixed it by having Tasker disable IPv6 on wifi whenever it connects to a wifi network (it's re-enabled if you disable wifi or reboot). Run this as root:
echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
I wonder if this is just a bug in the chipset, or if it's a driver issue that can be fixed in a later update.
I had the exact same issue with mine (same router) and solved it by disabling WMM APSD in the router settings. Wireless>professional tab>5GHz drop down box>Enable WMM APSD>Disable.
A guy in the other GS4 Q&A forum gave me this solution and I haven't had an issue with it since.
I have this same issue... so when my Wi-Fi is dropping like that, I disable the Wi-Fi power save mode by dialing *#0011# then pushing the menu button and selecting the Wi-Fi option from the pop-up, the psm button is there. Fixes it every time, doesn't stick thru a reboot tho.

Hello, I'm having the same problem but I'm new to Tasker and don't know where to put that command. Would you mind showing me how to implement it please? Thanks.
Edit: Nevermind, I think I figured it out.

I'm running SACS Custom 7.1 with Faux kernal, and since I update to 7.1 from v7, my phone doesn't save any wifi profiles I connect to. Another thing I've noticed is no image shows up when recieving a call, so I have no idea who is calling. I got a 3rd party caller id from the market to fix that, but still a strange issue.
I am experianced with phones, but haven't posed enough here to post in SACs page, so any ideas would be helpful.
I tried looking at settings from 3minit or XPOSED, but nothing has changed since V7, so I'm wondering where to look.
The wifi profile shows up in data/misc/wifi/wpa_supplicant.conf, but only the one I am connected to at the time. If i disconnect and reconnect I need to re-enter the password.
Not important but annoying.
Thanks for your help in advance, you guys are awesome!

Wifi issue is faux kernel flash a different kernel. A module from xpose is the culprit sorry I forgot which one was it. To solve all your problems just do a clean install of v7.1 and when doing that make sure you click stock kernel or flash a preferred kernel. I dont use xpose so I dont have that problem so its your choice if you want to use it just read like 10 pages from the thread to find your answer.

I have to do this same thing and it works for me perfectly. A little bit of a hassle after reboots, but it works. I sent this to Samsung and they've opened a ticket on it (reportedly) to be addressed as they've had a lot of complaints about WiFi areas with multiple Access Points.
Hi,
when I ride my car, I usually turn on the car mode, WiFi and Bluetooth. I start at home where I am connected to my WiFi and connect the Bluetooth audio. Everywhere works fine.
But once I reach my destination where they also have WiFi the phone tries to connect to it. This causes the Bluetooth to shut down completely and only a reboot of the phone makes it possible to re-activate it.
I just started to experience this issue. Is it possibly related to the latest Android update? Does anyone know a fix?
Thank you!
Change the Wi-Fi band.
Go to Wi-Fi, click 3 dots menu, select Advanced and change the frequency band at 2.4ghz.

Hi, Thank you very much for your recommendation. The situation has improved since but I have had another two disconnects:
- once Bluetooth reconnected itself
- the second time the situation was again as described above
Any further ideas?
I'm still facing the issue in irregular patterns. Are there other possibilities than changing the WiFi band?
Try other radio maybe.
.48 seems to work fine for many users

Hi, thank you!
I just tried to find an option where to change the radio but couldn't find it. Could you please tell me where it is?
However, I discovered the "scanning always available". Does this drain the battery? If not, I could turn off WiFi in my car and always put this option instead. The only reason why I turn on WiFi in the car is to improve the GPS location and I usually turn it off cause it drains the battery when I am on campus and it keeps reconnecting to several WiFis.

Here are the radios.

Just flash through custom recovery.
And for GPS you shouldn't need Wi-Fi or other data.
Mine locks in seconds, the moment I activate the navigation.

Hi,
I'm experiencing annoying WiFi/Blueooth problems and I need your input on this one.
This is a very common one that has been present since the beginning of N4's life, but isn't present in all Android builds. I haven't found any nice, neat thread with proper info and description of the problem, so I'm posting one myself.
Specifics of the WiFi + Bluetooth problem are:
1. Bluetooth is ON, mouse and keyboard connected.
2. Wifi is ON, connected to a 2.4GH AP and being used.
3. After a very short period of time (mostly from 20-60s, sometimes upto 3minutes) the WiFi is still connected, but internet connection drops - pinging or opening a new browser page won't get the connection back.
4. Restarting WiFi gets internet back, but just for as long as in .3
5. If I turn one of the bluetooth devices off, internet immediately comes back online, but only like in .3
6. When Bluetooth is on with no devices connected everything is fine.
7. Turning Bluetooth on and connecting devices first, then Wifi doesn't make a difference (some poeple say this helps).
8. Router and bluetooth devices DO NOT matter and im am 100% sure of that - tested them with Note II with no problems.
This is obviously interference, but Nexus software/driver is bugged and won't handle this interference - won't reestablish connection when it's dropped (timeout).
My Nexus 4 info:
Android version: 5.1.1
Builds with the issue: CM12.1-20150829-nightly-mako / Euphoria-OS 1.1 (AUG 15) and previous Euphoria OS builds.
There are few apps that might be a workaround for this issue. They monitor the connection and reestablish it whenever it drops.
I've tested the Wifi Fixer app and it does work for me. So this is one of efficient workarounds, but still using internet is annoying as there are few seconds breaks in service at least once every 3mins, but mostly every 20-60secs.
LOGCAT:
I was just running continuos ICMP pinging and staring at the latency output while adb logcat was running on PC.
Suddenly, without any reason I could think of, connection got dropped and host become unreachable. I tried to reproduce this occurence, but unfortunetly it's "random" and appears without any apparent reason.
Code:
D/HeadsetStateMachine(21494): Disconnected process message: 10, size: 0
D/audio_hw_primary(191): disable_audio_route: reset and update mixer path: low-latency-playback
D/audio_hw_primary(191): disable_snd_device: snd_device(2: speaker)
E/WifiStateMachine(633): WifiStateMachine CMD_START_SCAN source -2 txSuccessRate=3.63 rxSuccessRate=4.05 targetRoamBSSID=any RSSI=-50
D/HeadsetStateMachine(21494): Disconnected process message: 10, size: 0
WIFI BAND:
Can't detect or connect to my 5GHz SSID while I'm connected to bluetooth devices.
Even if I connect to a 5GHz AP first and then switch BT on, the network will drop internet connection shortly or whole Wifi connection will drop (unlike with 2.4GHz).
I can test few ROMs, but it'd be better if I knew which specifically could work. Don't wanna waste time. I want to focus latest builds obviously - interested in Lollipop only.
So if you've came across this problem and somehow got it fixed then please share a solution.
Lately I've been having serious trouble connecting to Wifi networks. This occurs both on my workplace network and home network. I have tried resetting my Network Config, but this didn't fix anything. The only thing I've found that will allow me to connect to Wifi is to restart the device - but I have to do this every time I want to connect to a different Wifi network than I was connected to previously.
One strange thing that happens with this is that when I disable Wifi - whether it be via quick settings or in settings - it doesn't actually disable Wifi. The toggle switches to off, but I'm still able to see nearby Wifi networks. The only way to fully disable Wifi is to enable Airplane Mode.
This has been happening recently since I performed a Factory Reset, flashed the latest factory image, and rooted.
Anyway, any help with this would be greatly appreciated!
UPDATE: Looks like switching from Automatic Wi-F- frequency band to 2.4 GHz fixes the issue, but that's not really ideal, as I prefer my 5 GHz network at home.
Hi there,
I have my S8 Exynox version for more than one week and I am facing some strange issues that I cannot explain and I have never experienced them with my previous phones.
I have WiFi router (2.4GHz/5GHz) running OpenWRT and S8 is disconnecting or keeping connected but losing internet access. Many times when I unlock the phone I can see that it is not connected to WiFi and just connecting or there is a message "Connected to XXXX" indicated that the connection was somehow re-initiated. It seems to be more stable if I remove 5GHz network connection but still not reliable.
This is even more strange. When I enable WiFi on S8 and let it connect I am facing network connection dropouts on my LAN not only on WiFi but even on cable. I am listening network radio and the sound disappears randomly and the issue is gone if I disable WiFi on S8. Sometimes I even have to restart the router.
Settings changes randomly. I was navigating with Waze and there was no speed indication. I stopped and found out that it was disabled in settings although it was enabled my previous drive. And another time LTE was suddenly disabled. There was 3G/2G selected in Connection -> Mobile network -> Mode.
I am using Dropsync to synchronize several Dropbox folders with my phone. One of them is synchronized to Share folder in local storage. Yesterday I found out that there is some sync problem in Dropsync and it turned out that Share folder is not existing. Some process has obviously deleted that folder. Could it be that I run optimization in device maintenance?
I am using Nova launcher with Morena icon theme. I have selected some icon for Samsung calendar to have is consistent with the icon theme but it randomly changes to stock icon during the night.
It forgot BT pairing with my Garmin Forerunner. I had to pair them again.
I have enabled volume sync when I connected my JayBird earbuds for the first time but it was disabled again few days ago.
Does anybody else have issues like this?
Experienced the WiFi issues in the beginning too, it doesn't kill my ping any more at least not majorly and it seems to have stopped not being able to connect to my router properly. Can't say anything about the rest.
And how did you solve the WiFi issue?

I didn't, it resolved with time, it did seem to stop after rebooting my router one last time but I doubt that's it as I already did that once and the issue happened again.
