WiFi stuck - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I've really never been on 4.4 before, but I just switched yesterday and even though the WiFi is set to only on when charging my settings show it's always running and I'm not sure if that's killing my battery or not...btw I'm running Negalite

Rootchecker and returning to stock

Hey guys I'm on an AT&T D800... since Monday afternoon my phone had been unusable... it got extremely hot both front and back near the mid to top of the phone... and was just chewing through battery 31% in 15 minutes... so I powered down and left it numerous times on different stock based rooms and still no luck it would just overheat till it shutdown or battery died if I didn't turn it off... I managed to get it charged enough to restore my stock backup, unroot, and put the stock recovery back on and then did 2 factory resets with still no change... so I called at&t and they sent out a warranty replacement which will be here tomorrow.. so my question is do any of these return to stock methods actually clear rootchecker? That's my only worry that they'll see that and nail me the retail price of the phone... I didn't use a custom kernel just the roms...
I see conflicting stories from people saying yes it does it clear rootchecker and others saying no.. I would just try but I don't have WiFi so I don't burn up my months data just to find out it didn't work.
The phone seems to be working fine since I powered it up 2 hours ago but I'm worried about any residual/repeat issues or decreased lifespan of phone from the overheating issues
Thanks in advance!

Flashing a Stock .kdz works completely. Perhaps you should read this sticky: http://forum.xda-developers.com/showthread.php?t=2432476
Thanks I've read that one before but I've also read other threads that say it still shows rooted when booted into download mode even after doing this reflashing

Did you check to see why the battery was being depleted so fast? I am willing to bet the phone itself was fine, but some app was utilizing the entire CPU, which would heat the phone up and kill the battery quickly.
Which means it's entirely possible you'll have that issue with the new one as well.

Yeah but after 2 factory reset there were only unused factory installed apps

The rom restores I can see that holding true but after 2 complete resets and not adding any apps... not even setting up any Google services I don't know what it would be

Wifi issues do I need to switch while I still can

I just got the s4 and its total stock but it keeps dropping on and off wifi. In fact in settings it sometimes says I have poor wifi conection. But I know my router is good and my wifes g2 has no problems. I read online there is alot of issues sinve the 4.3 update and even after the patch. I also read samsung is not going to do anything there blaming sprint or your wifi. Should I switch to the g2 while I still can or hold out for a fix or does anyone know a fix?

Also it took 4 hours to set up phone. Most was the crazy slow download of apps from play store and updates from play store. Small apps would take 10 minutes to download then about 5 to install while on my wifes g2 same app same time downloaded and installed in under a minute

WiFi switching on and off is probably under wifi settings. Just turn it off and it will stop switching on and off.

I tried that even did the ##code to get into WiFi and turn off WiFi saver. Nothing worked and then it started saying no mobile data connection but I was on lte and it worked. Plus I was getting that Knox problem so I just went to the g2. Thanks though

4.4.2 problem s

1. Why did so many apps disappear?
2. Why is home WiFi "unstable" Internet connection ?
FYI OTA upDate worked on safe root

If you're talking about personal apps you should reboot the phone. They will reappear. For WiFi I've had no real issues. Just spent the weekend at my cousins house and I wasnt disconnected at all.

I forget the actual name of the setting but look for something like "smart mode" under WiFi settings as well as avoid poor connections and turn both of those off. See if that helps you at all. Did for me
Verizon S4
Liquid Smooth 4.4
&
Sprint S4
Negalite 4.4

Bluetooth battery drain?

Stock G2, AT&T. Running KitKat latest update.
Since KK arrived, I've had major battery drain by bluetooth. I leave bluetooth off, but it is always the highest power user in standby. Anyone else have this, or know how to fix it?

the way I see Bluetooth is now like wifi even when it's off it's on but since it's in a low energy state it really shouldn't be draining your battery I've easily gotten 15+ hours while actually using the Bluetooth to play games with my moga controller and using my deck
I have the same issue.. im stock t-mobile on kit kat... and im currently getting the same amount of battery i was getting on my lg nexus 5.. which kind of sucked.. I dont think theres a fix yet
My battery life is horrible and Idk what to do

Maybe Phone Carrier
I think it's maybe related to your carrier too. They change something in the ROM to make compatible with network then release to your phone. For International and Korean Version is ok. But can you try to reset, if the problem still exist?
I have sprint and have been dealing with same issue since kk update. I don't even use bluetooth, always off, but yet saying keep awake 5hrs on a battery cycle.
I only experience it when I have wifi on at the same time, its weird.
From my experience on my phone, it's just a wrong reporting. Even with BT allegedly draining according to the battery stats, my battery life is still the same as before.

Is your wifi enabled at all? If it's enabled and not connected then chances are it could be scanning for networks which would cause significant power drain.

I went into the wifi /menu/advanced and turnedoff the wifi scanning for Google Apps and location even when wifi off. That is insane! Made an hour a day difference in usage.
On a side note, the signal on this firmware is better than. The wife's retail version has no signal in a store and I had 4g with two bars

I feel like my battery life is slightly worse as well. Although that could be attributed to what seems like weaker data signal. So idle time seems to hold up just as well. But the battery seems to drain faster when using data. I was going to monitor it for several more days and if it's still bad, i'm going to try flashing the MJE modem

For those running 4.4.2 on the Verison Note 3...did you all have to subscribe to the Chinese bot-net via Kingo Root, or is there another method to install a ROM? Is Safestrap the only option, or is there a full recovery available?
Thanks.
