When I go into the settings to enable wifi I get the following messages back to back, either one can show up first:
"unable to save the network"
"unable to scan networks"
When this started the phone was not rooted.
I rooted the phone in an attempt to fix this.
I deleted /etc/wifi/wpa_supplicant.conf after backing it up.
This fix was suggested in the EVO forum, however it did not work for me, also the wpa_supplicant.conf was not recreated, and I was under the impression that it would be.
Has anyone had this issue and fixed it without doing a factory reset?

Now that you are rooted, i would say do a nandroid backup, then do a factory reset to see if that fixes your issue, if not, then you have a backup to restore to incase it does not work, if it does, then your good to go, if not restore and you are no worse off.

How do you do a NANDROID backup? Using Koush's recovery image? I saw initial unstability issues so didn't bother with it. I'm still hoping to see Amon Ra's recovery.
oh jeez i'm glad this thread is here. I have the exact same problem now. I don't remember anything significant enough to screw up the wifi, but I did use XBMC and Allshare as a trial run and it worked fine and I was amazed.
The next day the wifi is gone and 'unable to scan networks' gets on.
Can somebody help with this issue?
I will nandroid back soon and see how it goes down.

that is a link to the how to, just follow the first post, once you have clockwork recovery installed do a nandroid back up through ROM Manager,(if that is the koush recovery you said you had your set, just install the app) try a factory reset after backup and see if that fixes your problem, if it does then your set, if it does not fix it, then you can always do a restore and it will put your phone right back to how you had it when you did the back up.
Just ensure that you dont partition your sdcard with the rom manager, it will wipe your whole phone internal sdcard, not the external one, you should have no reason to do this anyways, just wanted to let you know not to try for fun. as it is not one of the steps to backup or restore anyways.
I had the same problem and found that the problem seems to stem from Allshare. I used it briefly and disconnected from WiFi, later that night, I enabled WiFi and had this problem. Today I opened Allshare and it prompted me to turn on WiFi, I was redirected to the WiFi menu and attempted to turn it on again. Of course it failed the first time, but I repeated this process of opening Allshare and pressing "Back" when it tried to redirect me to the WiFi menu. Doing this two or three times somehow managed to get my WiFi finally to recognize and now it all works. I would say, that if anyone is to run into this issue, I think it's Allshare related. This is what I did to fix it, hope it helps.
thank you for that. i'll go try it out
None of that works. Does any developers or anyone with some experience have any advice or fixes? Much appreciated.

I'm pretty sure it had something to do with Allshare or XBMC. I think it has something to do with the phone having to scan a network for other devices to obtain indexes. When I was messing with allshare, I disabled the wifi in the middle of the phone attempting to scan my network for my media servers. That's the only thing I did, so it's the only thing that could have caused my issue. When I opened allshare again it asked me to enable wifi, I received the error a couple of more times then after a few times it fixed itself, which led me to believe that it was allshare that caused the issue to begin with. I'm hoping that samsung is aware of this bug.
Same issue, first time I restored a Nandroid backup to get things rolling again. This time I was testing a new DLNA server at home with AllShare, since then Wifi wont stay on. I have sent a message to Samsung support about it. Rebooting doesn't seem to help, not sure how to do a workaround.
Best thing is to go into AllShare, make sure Wifi is on, wait a few seconds and then go to home screen. Usually after a few tries the Wifi setting will stick.
Like I said, all I did was to try and go in and out of Allshare back and forth between the Wifi application and enabling/disabling Wifi. After a few tries, it magically enabled successfully and worked. I wish I had a better fix or better advice, but all I can say is that I just had Wifi disabled, attempted to launch Allshare, Allshare told me to enable Wifi, so it automatically took me to the Wifi settings menu, I enabled it, received the error, went back to allshare, it sent me to settings again, I enabled wifi again and immediately pressed back to get back into Allshare, at which point I just bounced back and forth between the two, hitting back immediately to get back into Allshare, and somehow Wifi worked. This leads me to believe that Allshare didn't finish "something" with wifi, so interrupting Allshare in the middle of a network scan is bad.
already returned one unit to tmobile because of this issue a couple weeks ago had no idea it was related to allshare. makes sense i was using it to try to stream to my xbox the day before
Looks like a pattern to me!
Also, if you are using Juice Defender, you may have a setting that is turning off WiFi.
Fixed for me
So I had the same problem. Not with allshare, never use it. Just randomly stopped working. Anyway, follow the link below, it fixed the problem. It does require root and editing the conf file rather than deleting it. I had a missing } from the end of one of my entries for some reason. I removed all of the saved ssid's and put in the missing } to the end of the t-mobile entry and no more problem!

I'm rooted, deleting that file worked fine for me and it was recreated (the one early in the thread)

It's worked . Thank you so much.
none of the "fixes" posted work. im bone stock, running eclair. same wifi errors as the op. The phone is to be used as a wifi only device, since the sim is not active. is there a real fix for this?
This is helpful information. thanks.
I'm not sure it hasn't been asked before, but I couldn't find the topic so far (maybe I haven't searched thoroughly, in this case I apologize). I'm using a DesireHD NAND ROM. So the problem is:
After letting my battery drain to near empty, I tried to turn on my phone for a few times, but I didn't watch the whole boot sequence, I was just surprised to find it turned off again after a while. Then I figured I have very low battery, then i plugged on to the wall charger. Then everything went fine, the phone booted and Sense loaded. I got a few error messages, like: The application (<application name>) has stopped unexpectedly. Please try again. The only choice was to Force close the application. Then came the first strange things, namely:
- a few applications' icons are shown as stock android package files
- practically no application is functioning, apart from Contacts and some fundamental programs, they all give the error message like the one above.
I guess it has something to do with me letting the battery drain that low, but I don't have a clue how to fix it. I wouldn't like to hard reset my phone, if there is other way.
Thanks for any help in advance!
You should try to fix permissions. If that doesn't work, start to see whether your rom recognizes your sd card. If it does, I would recommend a total wipe and reinstall. Make sure to wipe cache, etc. This should be a last resort though, as you will have to reinstall everything and there is risk involved.
As a last *last* resort, task29. As with the reinstall, risk is involved. If you don't pay attention and do these correctly you may be phone shopping soon.

I found the Fix Permissions option in the ROM Manager, ran it, and rebooted. Now background processes (Appkik, SetCPU) seem to be working fine, though the icon of Dolphin browser is still missing and some app icons are still shown as android package files, and are not working. This has happened before, don't remember exactly what made them go away, but they somehow disappeared. Thanks a lot!
I keep having to reconnect my previously paired bluetooth devices, and I believe this started after upgrading to Marshmallow. Initially, my devices seemed to unpair infrequently, like maybe every 10-14 days. But now, for whatever reason, it is happening more frequently and sometimes daily.
After reading through the forums here and at AC, I thought it might be happening because I rename the devices after I pair them, but that didn't solve the problem when I stopped that.
After Marshmallow, Android Pay required a screen lock to use, which I never had done in the past, so I also enabled Smart Lock and set my paired bluetooth devices as trusted devices. I just disabled all of that (screen lock, android pay and smart lock) so I maybe that will solve the problem, but I suspect it won't.
Anybody have any ideas?
Hi,
I have the exact same issue!
VEry annoying!
Clearing, hard reseting, repairing etc... tried EVERYTHING!
Now i also set smart lock and trusted devices.. Will go to a meeting and back, will test it on the way.

Well, that didn't work for me. I also tried clearing the cache from the boot menu, but it's still dropping my paired BT devices.
My new Square Up Contactless + Chip credit card reader arrived yesterday. Unlike their previous credit card readers that connect through the earphone jack, this one connects through BT. I cannot get it to connect to my XPE, but am able to connect it to my Moto X 2nd Gen.
I really hope this is a Marshmallow issue that will be fixed soon, but the lack of responses has me concerned that it won't.
I tried resetting the network settings and wiping the cache, neither of which fixed it. I decided it was time to do a full factory reset, but that didn't fix it either. Any other ideas?
I going to assume you are unrooted... But either way if you can change your SELinux to permissive that might help your Bluetooth issue there is this app here that might help out

Got the new phone from Motorola a couple of days ago. After reinstalling all my apps and customizations, including renaming my device and the 4 Bluetooth device I connect to, I started to experience the same problem. Not initially, but soon after I turned on the new System UI Tweak option.
So, I turned off the feature and it hasn't happened since. It has been a few days and I have restart (soft reset) several times, which I found would usually trigger the loss of pairing, so I'm keeping my fingers crossed that it was related to the UI tweaker.
This is a problem I didn't notice right away. I attribute it to the QF2 update because wife also has an S7 and experiences exactly the same issue.
In a matter of hours after reboot the internal sensors stop working or behave erratically. Sometimes the phone would go to the lowest brightness, the screen will not turn off by the proximity sensors during a conversation. Functions relying on shaking the phone stop working. Some (but for some reason not all) apps don't switch to the landscape mode. I downloaded several sensor testing apps and they confirmed my suspicions. After the reboot everything works, but several hours later sensors start showing random values or "no data".
Does anyone else have the same problem? With two affected phones in my possession it can't be a random fluke.
The phones are not rooted.
I had an issue where the phone no longer responded to "OK Google". Turns out I uninstalled all the updates to the "Google" app and reinstalled them from Google Play and that fixed it. I wasn't sure if it was the OTA for the phone or something else, but the OTA might have jacked something up somewhere. Have you cleared cache and such to see if that fixes it? Otherwise, I'm having no issues with the sensors not working.
Thanks for your suggestion. My phones are set for manual updates. I updated everything and rebooted. The sensors worked fo about 12 hours and stopped. Which cache you recommend to purge? Google app?
OK this is weird.
I have my Note 3 running on Norma ROM v17 without problems and a ton of apps installed.
Few days ago I tried to use smart select (with the pen) when a toast message prompted "Unable to capture screenshot. Prevented by security policy." . Well I just ignored for the moment thinking that something went wrong with facebook app which I was trying to capture.
However this seems to be permanent behavior. I can't take screenshots neither by Power + Home combination neither by SmartCapture not even if I try to use a third party application!
Did anyone had faced the same problem again?
Can somebody point me to the direction to solve this?
One last addition.
I don't know if it is related to this problem but I have to report it. The device boot animation is getting resized to top left of the screen every time the device boots. What on earth can cause this?
I"m back wirh a solution.
I was for more days trying to discover how to solve this problem.
Finally I decided to backup my data and wipe the system.
And then I noticed a command lying in the menu called "Reset settings" which I had to try instead of resetting to factory default the phone.
So this command cleared the settings (I really dont know which particular settings were cleared though ) without losing my apps, data, phone setup etc.
The problem fixed.
:good:
