[Q] My samsung galaxy s4 won't remember my wifi network

Okay so I have a Samsung Galaxy S4 from sprint, I love the phone it’s great. I was on the mdl update stock rooted and everything was working fine with wifi. Then I did a factory reset updated to mf9 (the latest update) and then rooted it still stock. Now my phone will connect to wifi if I manually connect to it and works fine, however, if I disable and reenable wifi or restart the phone or leave my house and come back, it will not reconnect to my network automatically, I have to select it myself and put the security key in everytime. When I disable and reenable my wifi it will show “secured” under my network, making it seem as if it never tried to save the network in the first place, So it won't automatically connect like it use to on the mdl update, because it seems as if it forgets it when it disconnects.
I tried even connecting and then forgetting the network and then connecting again to see if that would fix it but it didn’t.
The weird thing is that at my work it remembered the network and connects automatically and when I’m in range. And when I’m away from work I can see it saying “not in range”. Why isn’t my home network doing the same thing, and how do I fix this? (btw I really don’t want to do another factory reset if I don’t have to.)
-I have a 2wire 3800HGV-B router.

Okay well I fixed it by unrooting and using odin to go back two updates prior to mf9, then did 2 ota's back to mf9 and rooted again. all is working fine, also fixed the phone's getting too hot problem and battery last longer than ever.

it's your kernel that was causing this...for future reference, if you're on mf9 with the stock mf9 kernel and do not want to have to wipe your phone to fix this, you can use ShabbyPenguin's kernel...i had this issue before on my s4 and this worked for me...why the rooted stock rom doesnt like the stock kernel for wifi blows my mind...lol

How was it going on? Do you still have the problem with the wifi?
Perhaps you can try this: http://forum.xda-developers.com/show...56&postcount=2 (Greatly appreciated and high credit to dajumper's work.)
This works on my I337 NI1 Unlocked Rooted. I uses ES Explorer with Root Explorer enabled.
I went to the "system " folder in the device, scrolled down until I found "build prop" then edited using ES Explorer Note Editor.

bluetooth issues since updates ***BEER TOKENS IF FIXED!!!

hi guys, need help desperately (willing to send a few beer tokens via paypal if someone can help me sort this ASAP!!!)
since a recent auto update to 5.0 on my samsung S5 (uk on o2 network) im finding my bluetooth won't auto connect or store/save connections
i have tried clearing data and restarting, as well as deleting and re connecting but its not working
before, i would pair to my alpine car stereo and it would ask to save this connection and that was it, and everytime i turned the car on, it would connect without having to put in a code or anything
now, every single time i get into the car, it asks to pair, it asks to allow access to phonebook etc, the whole process takes ages, and it still doesn't connect perfectly as the bluetooth logo on the stereo constantly flashes, this is a huge problem for me, as i have 9 points on my driving licence, some of which for using my phone so any more and i lose my driving licence

Full Factory reset since updating to Lollipop? Solves 99% of problems
To be honest, bluetooth not working is not really an excuse for 9 points for using your phone, you also have the option to not answer it when driving, or pull over first
---
EDIT - Try this too (You need to be rooted)
Open up build.prop in /system/ and edit this line
ro.securestorage.support=true
to
ro.securestorage.support=false
Reboot, set up your connections one more time, this time they should be saved and auto connect again, I have to do this for WiFI

i already have 6 points for unrelated driving offences,and 3 for using a satnav (when parked in a layby but the copper says my indicators were on and assumed i was pulling out even tho i was parked up and stopped with hazards on, but i suffered it as it was my first 3 points at the time) and just don't want to risk it, i drive and get 100+ calls a day work related so its hard without handsfree
trying the above, will let you know what happens

did a full restore on my phone, and its done the same
not sure how to do much else with the phone, so if anyones willing to guide me through it il happily pay them for their time
thanks

Did you try the secure.storage trick?
Pretty sure that's the same issue, I don't use BT, but it refuses to save WiFi passwords after a reboot unless I edit that line and reboot
You don't need to offer money for help, that's what people are here for anyway
If you don't mind tripping KNOX, which basically nulls warranty outside of the EU, you can use CF Auto Root to root and then you'll have permissions to edit that build.prop file

all the above makes no sense to me
iv had the phone a year, so it might be out of warranty anyway, is it a simple task if i watched a youtube video?
all my wifi passwords are fine btw

Yea it's pretty straight forward few videos here
https://www.youtube.com/results?search_query=cf+auto+root+galaxy+s5
But if your WiFi passwords are saving fine it might not be that afterall... worth a shot I suppose though, having root is always good, if for nothing else you can block adverts system wide
Basically you need this file if you S5 is the G900F
http://download.chainfire.eu/397/CF-Root/CF-Auto-Root/CF-Auto-Root-klte-kltexx-smg900f.zip
And ODIN
https://mega.co.nz/#!Exo3yADS!y7pFS5-9RVhp4vDxTRAQARAwkjyQAB_9mDZWfXkLqko
Put the phone into download mode (Volume Down & Home & Power) from a powered off state - then volume up when prompted
Extract CF Auto Root
Load the extracted file into AP in ODIN, wait for it to say it's happy, and hit Start
It will root the phone, then reboot the phone

Missing "HotSpot & Tethering" / Hotspot not functioning

So, I'm having a particularly strange issue here. I recently got this Sprint Note 4 and activated it. However, there appears to be a missing option under settings. Tethering and Hotspot is straight up gone. To clarify, I have pictures attached showing the item listing, and one without it.
Clarifications of troubleshooting I've tried so far:
I have attempted a factory reset of the device
I have attempted to do a reset with ##72786#
I have tried updating Profile, PRL,
I am using a DeOdexed PH4 6.0.1 ROM. I have tried reflashing per instruction (triple wiping Cache, Dalvik, Internal, System, etc)
I have tried flashing a STOCK OTA PH4 ROM to see if it would show up there. It does not.
I called Sprint technical support to reprovision my phone. They pushed out a a reprovisioning that I accepted. No change.
At one point, Wanam/Xposed was attempted to be installed. I checked for system/csc/features.xml. It was not there
http://forum.xda-developers.com/note-4-sprint/development/rom-stock-ph4-bloated-deodexed-t3473610/ is the custom ROM i'm using. However, it doesn't seem like a ROM specific issue.
If I use Activity Launcher or itools, i can access the actual wifi hotspot MENU (the toggle off and on, LAN settings, etc). I can enable it and the system will broadcast the SSID. However, if I try connecting to it, no devices are able to successfully connect.

here is the Activity Launcher referenced, for other readers:
http://forum.xda-developers.com/showpost.php?p=66713935&postcount=7
but anyways, regarding devices not being able to connect, sometimes the data connectivity (through hotspot only, not for the entire phone) will go dead if you don't start using it immediately after first unlocking and activating tether.
in my experiences, if you keep data alive by immediately connecting a device after your first time turning tether on (after unlock) by downloading a large file or somewhat frequently reloading web pages (on the connected device!) -- anything that will keep data sending and receiving -- it will stick, and the data service to connected device issues will stop.
it's not foolproof, it's not a silver bullet, but this is the method to the madness I have learned and worked for me many times when changing roms and even getting new phones.
it's been a couple months since I had to fiddle with it last, so I can't remember if it was necessary to re-unlock after a failed attempt at keeping data alive. you might only have to toggle data off then back on for another attempt.
when I had the problem of connected devices losing internet access, it would only happen after having worked for a few seconds to a few minutes. it'd work then abruptly stop, and this is my "fix"

My issue seems more in line with the devuces failing to validate to begin with. Not losing connection.

I had something like this before, I vaguely recall it having to do with using Odin vs. OTA stock. So did you try wiping your phone completely then Odin the stock PH4 tar, or did you OTA to PH4?

The very very very first time, I OTA'd to PH4. The next two tries were wiping completely and using the PH4 tar file. So both methods have been attempted.

I was referring to loss of internet connection, not signal related. I thought that was clear, sorry

I thought you meant loss of internet connection in the sense of anti-tether provisioning from Sprint. My phone's LTE never goes down (and I am able to still browse the internet from the mobile device while tethering).
The connected devices never successfully "connect". They aren't listed as connected devices under the mobile hotspot. My other Android phone (without mobile data) is forever connecting. My macbook claims it has an assigned IP but is "unable to access the internet". So I'm not sure what the hell is going on with that.
At this point, I have restored my Note 3 as my active device until I get this resolved. I'm willing to re-write everything down to the barest metal I can.
Somebody in another topic mentioned something about PIT. I don't know anything about that sort of thing. My knowledge extends about as far as installing recovery and flashing ROMs.
I'm confident I could follow procedure, but could use a guiding hand on where to go from here.

sounds like the tether unlock method you used was not done correctly, whether by whoever made it or yourself
method 2 in Galaxy Tools should work just fine. there are several threads in the Sprint note 4 seconds that contain the apk or ppl that will pm it to you. the author discontinued the public/free version of the app and now chargers $35+ per person for a 1 time use lol once you get a copy of the free one, make copies and store on multiple devices forever.
it's primarily for Sprint Sammy devices, so you prob won't see much if anything about it here in the collective note 4 forum.
may work on some boost or even tmo, but yeah.
edit:
you'll want either 3.1.5, easy install n msl read broken on MM and less features
or 3.1.8, troublesome install with msl read working but unreliably, more features.

Came back around to this, as I am running a multi-rom and am still encountering this issue. I never attempted any hotspot unlockers. The hotspot was missing from the get-go.

Just a thought and question: when you Odin stock tar to recover from this condition, are you using the rooted extended power menu to boot to download mode? Or, do you prevent the auto reboot of stock tar flash with Odin options?
A noted developer, @idone from Galaxy Tool app, once shared with me that rooted shortcut or preventing auto reboot can prevent the normal flash of Odin booting to recovery momentarily to set csc options. csc options flashed may not restore on any boots if you skip that initial auto boot.
The suggested method is to power down and pull battery for 30 seconds our more before reinserting battery and manually booting to downloaded mode. And do not uncheck auto reboot or pull battery but use Odin defaults and let phone auto boot. Doing this allows the phone to boot into recovery to do its thing briefly before booting system. I usually just let it perform the setup wizard and didn't activation just in case.
I rarely do the the data profile update or PRL because if letting the phone setup this way and phone prompts to reboot later, I believe this all done. But since this may allow ItsOn to bootstrap initialize, after flashing TWRP and backing up, I wipe internal memory and factory reset before flashing a custom ROM. Data format is optional; I don't always do that.
But if you do all that and don't see hotspot in Settings of stock, that's a problem. Maybe from dead stock, try KIES or Smart Switch to restore latest stock and check again?

Yotaphone 2 reboots by itself after after the screen switches off.

Hello
I have a Yotaphone 2 running android 5.0. I have a huge problem with the device which is, that the phone reboots automatically all by itself after the screen turns off. The screen timeout is set at 1 minute and once the screen goes off, the phone reboots! I don't know what the problem is but its making me crazy!
Note: The phone does not reboot if the screen doesn't turn off. So I changed the screen timeout to 30minutes. Also note that Wi-Fi doesn't start immediately. It doesn't even start most of the time and is stuck at "turning on"! And also, the phone isn't detecting my SIM Card!
Hope someone can solve my problem.

Wow, seems a lot of problems here. However you provided very few info about your phone.
1) Where did you buy it?
2) What have you done after you opened it, OTA? Which firmware was installed?
3) Have you tried factory reset by wiping data in the stock recovery? (Accessible with Vol+ and Power)
4) Have you tried to flash from scratch the RU .124 firmware with YotaFlasher?
5) The phone was behaving normally before or it's doing this as soon as you started using it?

I got the phone as a gift

-The phone was a gift from "Aramex Company".
-Yes, I have factory reset it! Note: It wasn't possible to reset it from settings because it would always get stuck in "Shutting Down" phase and nothing would happen. So I hard reset it.
-I found something strange going on though. Whenever I reset it, It would restart (after the reset is over) and say that "ANDROID IS UPGRADED TO 5.0".
I think it is upgrading by itself to 5.0.
-No, I haven't tried any flashing.
-Yes, the phone was working fine for a while and then started behaving like this!
Cheers!
(Thank You for your support and attention by the way)

Video
Hello!
I have made a video showing what the problems are! Please give me your e-mail so that I can send you the "Dropbox" link to the video.
Thank You!

I think the first thing to do here is to flash a clean firmware (RU or EU) on your phone via YotaFlasher, search here on xda how, and then report back if it's happen again! Seems that the firmware it was shipped with wansn't so stable.

Flashed it!

Hey!
As you had prescribed, I flashed it! First I flashed it with Android 5.0.0-ME1.1.60 and after opening the phone I used it for a while and the phone was same as before flashing! There was no difference at all! The phone was restarting on turning screen off as usual, the WiFi wasn't turning on, and the SIM wasn't being recognized!
But then I flashed it with Android 4.4.3-S01-003-ME1.0.3.61a and the phone is still rebooting by itself upon switching the screen off and the WiFi problem still persists! The WiFi just simply won't turn on. It's stuck at "turning on"! The SIM isn't recognized either! Also, the phone is restarting from the inside now (It wasn't restarting before. I had to keep the power button pressed every time I wanted to restart)! But NOTE that the phone still cannot be just shut down, it can only be restarted!
I don't know what to do!
Cheers

can you please help me find 4.4.3-S01-003-ME1.0.3.61a firmware. i tried yotaflasher and i cant make the program work. it exits close itself. i couldnt find any firmware folder in yotadevices ftp too. can you help me found the spesific firmware please?

Hi lgk350tr,
Why are you unable to make yotaflasher work, it is a pretty simple application. Have you tried to see instruction videos on YouTube on how to use it? Instructions are also available on XDA Developers' website. ( https://forum.xda-developers.com/yotaphone-one/general/yota-flasher-download-t3480922 )
Don't hesitate to contact, for any problem!

Try flashing the hybrid modem mentioned in the general guide (Part 2).
Try flashing 2 times before rebooting.
If nothing helps, you could try lineageos, @angelll123 made a lengthy guide how to that in the post quoted here , also check my comment.

Is this what you mean?

Thank You

I do experience similar issue, but only recently. I haven't done anything like flashing or upgrading my phone, it started by itself .
I am experiencing reboots whenever battery drops below about two thirds of its capacity. Also, charging and handling some load prevents this.
Note that my Yotaphone has both displays damaged. Still working though.

XT1644 No longer connects to any PC

I have been going nuts as of late trying to figure what happened with my Moto G4+. It was working fine, could connect to my pc no problem, then all of a sudden out of the blue, nothing. It only connects as a charger. I've checked it with different USB cables, different ports, even 3 different computers. Still will only connect as a charger. I've even tried it in recovery mode, still not recognized by any computer. I have not restored the phone as of yet due to a ton of pictures and whatsapp chats that I need to save. I have installed Xender to start to move some stuff off the phone, but I'm not too sure that a factory restore would help this. I have read that it could be a USB issue with the phone, either the port or the chip it uses itself. While I know I can replace the port, the chip is beyond what I have equipment for. I have turned on developer mode, and its set the USB mode to MTP by default, I've tried changing it to PTP as well, but the phone will only charge and is never recognized by the pc. All software and drivers have been updated, uninstalled thoroughly, reinstalled multiple times to no avail.
Is there any chance that this IS some form of software thing? Or am i just going to have to use the Zender app to move things between my phone and pc from now on. Until I can possibly send it off to Lenovo since it IS under warranty.
Any help is appreciated.

Just got off the phone with Lenovo/Motorola, and they are giving me the option that I wasn't wanting to hear, do a complete factory reset on the phone after removing the account information from the phone. Gee, that's what I was trying to avoid. Looks like I'll have to figure a way to completely back up the phone via wireless and hope I can save all my data needed to restore it later.
Will be trying the factory reset, but I'm not feeling very good about this at the moment. Will update later when I can get this done. But in the meantime, please suggestions.
Thank you again.

Provide some more info about what ROM you're running, etc... The more info you can provide about your situation, the more likely you're gonna be helped.
What ROM:
Stock? If so, what version and security patch?
Custom ROM? If so, which one and build date..?
I also have the xt1644 and don't have any issues whatsoever connecting to my Laptop, granted I run Linux on my personal PC. I also have zero trouble connecting to the PC's at my work which all run Windoze.
You mentioned you've tried connecting to your PC thru Recovery, so I would have to assume you have TWRP installed, no? If so, which version and by whom?

I'm running full stock room, no mods, build NJPS25.93-14-4, security patch of March 1, 2017. As for the recovery mode, that was the stock recover/bootloader. To where it should be raw adp mode. Even in that mode it is never seen by the computers I've tried. I can't install the newest security update because it won't mount internal nor external memory. I'm at work at the moment and if you need any more information, please let me know.
Thank you

Did the factory reset work? As I'm suffering from a similar problem

Have not done the reset yet, still finding the best way to back up everything, plus finding the time. Will be doing it sometime this weekend though

I just did the compete factory reset, and as i feared, it made no difference. So all my data is gone (saved what I could) and will have to figure a way to get a backup phone working while I have to send off the phone for repair. At least it's under warranty.

I have the same problem. I didn't do the factory reset (yet), but you confirmed my fear, the factory reset won't fix it. Too bad my phone isn't under warranty anymore.
Did you send it for repair?
What was the problem after all?
My XT1640 seems to be falling apart. Bluetooth stoped working out of the blue. Can't read SD card anymore and now USB connection isn't working.

My apologies for not doing a follow up post. I was able to send it back to Lenovo and the replaced the phone so it's back up and running fine. If it's out of warranty, then I'm not sure what avenue you can take aside from maybe finding one that's got severe screen damage but a good non blacklisted board and change it out. Aside from that, I can't tell you what they found wrong with it. I would assume the usb chip may have gone out, but without knowing the fate of my original phone, I can't say.
