Wifi connecting/slow issues

Ok in my house hold, I have a note 4 and a note 3, both phones drop wifi connections, and has very slow internet, sometimes its fine, but more often its not. Wifi is full bars.
I know its the phones, and not the wifi, At work my note 4 also does the same thing on my companys wifi, and the note 3 as well.
What the heck is wrong, Ive tried everything on both phones to fix it. Factory reset being the biggest thing that should have solved the issues.
Whats going on?

Yeah have you seen the massive thread here: http://forum.xda-developers.com/note-4-att/help/wifi-performance-horrible-t2921653/page4
About 1/3rd are having WiFi issues, the 2/3rd like to say its not their problem go buy another phone.

No answers in that thread. Just a bunch of blah blah blah lol.

I'm also having this issue. Seems random but its causing me to use alot of extra data.
Seems like when the phone locks or sleeps that is when it disconnects. I have went into the settings and changed to to stay connect in sleep but that didn't fix it. I have also factory reset.

Don't have that "smart Switch" option checked, do you? I had this problem when that was selected. unchecked it and it went away.

I have the same issue and don't wanna take my phone back if this is a confirmed software issue.

[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!

Wifi problems after mm update

I've checked around and have seen other phones with the issue, but I've tried the fixes like forgetting network and resetting network settings. Ever since mm, every time my phone screen shuts off, it disconnects from wifi, kind of. I will still be connected jn settings, but it says no Internet available. I have to reconnect every time, and then it will work until my screen goes off again. I feel like this is killing my data since I don't always notice it. Has anyone had this problem and fixed it? I'm completely stock, no root or anything. Just did a factory reset a week ago and hoping I don't have to do it again since I'm finally set back up.

Have this issue with both wifi and mobile data. Mine doesnt matter whether the screens been off or not. Its like it goes to sleep periodically no matter what. Never had the issue until the latest update. Its not tied to a specific app, so its either the radio or a bug in the phone.

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.

Anyone had any luck getting rid of the wifi disconnect? The issue where wifi disconnects showing a ! next to the wifi symbol on the status bar?

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.

Phone constantly locks and sometimes unlocks

Hi, i have a big issue with this phone, i bought it like 2 weeks ago.
Since the 2nd day of use, i started to experience this issue, sometimes and usually when im not using wifi but mobile data, the screen goes to lockscreen, if i try to unlock it will lock again and that happens a couple of times, maybe 2, 3, 4, 5 times, sometimes i have to press lock button and try again. its really annoying, because somtimes it doesnt happen in a lot of time and then after 1 hour in the street and while im using it it locks and unlocks like crazy.
i did a soft factory reset but didnt work, i even tried in safe mode and it still happens.
yesteday i noticed that it even wakes up for no reason, that happened while i was driving in a highway, it suddenly wakes up like if i touched it, i disabled every feature about auto waking (like 2 touch, motion detection) but it still happens.
the only thing that makes it stop is if i switch airplane mode, so i guess maybe its something related to network (not wifi or location or mobile data because i disabled those and still happened), but when it is in airplane mode it will work fine, obv thats not a real solution.
i tried disabling and uninstalling a lot of apps but i cant figure out whats making this, im pretty sure its software problem, something related to network but i dont know.
do you have any ideas? even if i take it to tech service it will be hard to show them because sometimes it doesnt happen in hours.

anybody has an idea what could be causing my phone to lock for no reason while using it on the street?

Your phone gone kaboom

I have same problem, the problem is caused by the weak signals,which means that your phone connectivity is constantly changing, for example on a highway or in a basement. Solutions I have none, just waiting samsung to make a fix

Yes, thats exactly the problem. When signal is weak the phone locks or unlocks. I asked for a new phone at the store and they gave me a new one.

(Delete spaces in link between htt and ps)
Btw i don't think this is a software problem because if it was a software problem all phones would having this issue. I think it's a problem with some hardware failing in some phones. IMEI of failed phone is 356711101439414 check if yours is similar
