I've been having issues with this phone overheating since I originally got it. Today, about 50 minutes after boot, the battery had gone from 100 to ~60%, and the temperature was 46 Celsius. The issue is that it regularly gets that hot. Putting it in airplane mode does stop the overheating, but I can't figure out what app or service is using the radios constantly. (Another issue I have noticed recently is really slow 3g speeds, but I don't know if that has any connection to it.) If anyone has any ideas, please tell me.

Sounds like you have a defective phone. Call and get a replacement

Well then. I was hoping it was something that I was doing wrong. I'll probably go talk to the sprint people (there's a store about 5 minutes away) first though, see if they can test it.

You cant get it tested if its rooted, theyll tell you the test couldnt finish nd generally ask for 100$ for a replacement if u want it fixed

Well, what have you done to it? What software changes, apps installed? One might want to hope that its a simple software fix, have you backed your stuff up and done a factory reset, if that does not work what about doing another factory reset and formatting internal SD card (and removing external), if there are still issues, what firmware are you on?
So the main thing is to find out if it is actually defective (hard ware related) or software.
As TheChronicDroid pointed out, would be nice if Sprint could help but without the original ROM on it, they may not and hopefully won't make too much of an issue if its not the original one (wouldn't you hate it if the guy happened to remember that you came in before with a different ROM and have now put it back on original).
If you have changed the rom/rooted etc you can always put it back to original, including actually totally wiping and flashing an original sprint rom that will need some updates but will be totally original (is and SBF from memory).
Good luck;-)

This is really killing me, someone please help lol heres how it goes
On boot, takes a good bit for the 3G icon to appear, eventually Phone has 3G icon gray with arrows then switches to D [still gray], i click something like a browser or Slack Radio it goes to connect and if its fast enough it does [icon changes to RED/GREEN arrows] but usually its a gray D, then the icon disappears completely. After about 60 seconds or so the icon reappears and I can continuing surfing the net/listen to music..etc. Then after about a song or 2 this happens all over again. Im in place with good reception and i just dont know what could be going on here. I tried pulling battery, doing the *228 option 2...anyone know how i can fix this
just tried hard reset, no dice
A nice excuse to call verizon and get a replacement device (most likely for free).
I've called them, they try and shoot me over to Samsung, samsung trying to tell me to get a hold of my 3G service provider...verizon did tell me i was due to upgrade, but i love this phone (when 3G worked) i just dont understand what froyo did, when im downloading stuff it works fine, but as soon as I stop and try to access something use 3G i have to wait for the 3G to "reboot" so to speak cuz thats when it disappears for minute, then comes back for me to use...but with streaming music you can see how this is an issue
I was having this same problem when they were pushing the EA28 update a couple of weeks ago which never successfully updated to my device I might add. I went into the Verizon store and after the rep spent about 10min on the phone with whoever.... Told me they were sending me a new phone. Received new phone with the EA28 update already installed 3G and all data worked GREAT! Attempted the Froyo update 6 times yesterday all unsuccessful and now the new phone I have is having the exact same problems with data connection. Comments and ideas would be appreciated. But ya better believe I'm goin into Verizon if the update attempt I'm doing now doesnt work.
I'd get another replacement from verizon tbh. If then it still doesn't resolve your issues ask to speak with a manager and tell him your situation. They might hook you up with a free upgrade.
Im going to go down to the store so I can get a face to face and show them whats happening. I mean i just wanted to make sure this wasnt some new thing on Froyo that im not understanding. I see it goes "D" [dormant] but it shouldnt disappear and take a minute to start up and let me use it right...thats poppycock!
Are you using "juice defender" by any chance?
Sent from my SCH-I500 using XDA App
You're lucky that yours just takes a minute to re-establish the connection, mine will just keep giving me network errors and telling me to check network access ect., depending on what app/service I am trying to connect. Exactly the same things that happened when the EA28 updates kept failing on my last phone only 2weeks ago. Also the Froyo update that says will take 15min to download takes over an hour even though my 3g stays on constantly when downloading from Verizon.

Had it installed [but not in use] when I updated to Froyo, but I just did a hard reset and am still getting issues...
...my Froyo update came in in about a 1/2 hour or so, no drop issues ever when I was on 2.1, my 3G icon stayed in the status bar even when I was out of service range [it would go in to 1X] but on froyo its just disappearing no matter where i am]
This crap has happened ever since the first "froyo" modem leak for me (but not like I could call vzw and complain though until now) and had to resort to using the DL09 modem to increase my usage reliability by a small percentage. This crappy service only seems to affect people in certain regions, you all see where I live (look to the left) and you guys should update your profiles to reflect at least a region. I odin'd all the way to stock and did the ota's to froyo and ran stock froyo for 2 days with the same old ****ty results. I did get a replacement (in february) and still got the same exact dBm signal levels and data speeds at home that I had with the other device. But the voice mails with no missed calls and bulk texts and data lockups are really getting on my ****in' nerves. I'm so glad they finally did the ota cause I can guarantee that the issue will be wide spread in various regions. I spend all day driving around in a work truck with a coworker that has an epic (sprint) and he has absolute perfection in his service everywhere throughout the city. At the end of a 10 hour day I will have rebooted twice and have tws at 47% coworkers tws will be at 1% and he pays $35 less for unlimited everything, which is a kick in head too. Pondering etf to maintain my sanity and not be worried that my 70 year old mother is trying to call me with an emergency and having my **** go to voicemail. Now on to customer service to build a case. Ugh, pissed off rant over.
*edit* I use no juice defenders no task killers no set cpu or anything even remotely close to apps of that nature.
good day.
Not running juice defender or anything else for that matter, my phone is basically stock out of the box right now other than CWM 2.5.1, un-rooted. I did flash super user to phone after I received it, and that still appears in my apps list after factory reset but I am not rooted.
I've spent at least 8-10 hours [combined] searching the internet for issues like mine with the disappearing act the 3G icon is putting on, and i've noticed it to be a Froyo issue [even saw some complains on the Incredible on froyo and even on different networks other than verizon]. I'm not 100% sure its a Froyo bug, but either way it doesnt seem to affect everyone. I stream music a lot and i can't be having this damn 3G disappear on me and always reconnecting after like every 2 songs.....im off to verizon, i'll let you know what happens [tho they are prob going to offer me some kinda upgrade like they did on the phone, but i was happy with this phone at 2.1 and overall still am, i just want my 3G to stop glitching!]

I agree, just want my 3G to work the way it is suppose to. Dont really want an upgrade because I've never really gotten an upgrade that I actually thought was an UP-Grade. *From Verizon anyway* Still downloading software update, been well over an hour and at 73%. At this rate Verizon store will be closed by the time I'm done with this update attempt.
"UPDATE FAILED or INCOMPLETE. reason: IP_START_UPDATE" Anybody know the possible causes of this failure?
Sounds like you are indeed losing your IP address. I have also had sporadic problems but they seem to be in low service areas. Typically I remain stationary and use local wifi so it is unconfirmed.

Just got back from Verizon, non of the techs could figure it out, i got this phone awhile back from a friend [so naturally theres no warrenty..etc] so im stuck gonna have to hit craigslist and such to find a new one, then sell this one i guess
FINALLY FOUND A FIX [or should i say it found its way to me thanks to myself posting this issue on multiple forums lol] I can confirm that method 2 has worked for me. Dont just dial *228 with fascinate already activated, you have to remove the service completely [by activating another phone is how i did it] then reactivate it and you should be good to go.

I think I figured out when the data drops. The phone will lag to the point of inoperability, then the phone for some reason has trouble reconnecting to the tower. the only thing I have found to fix this is a factory data reset. I have been lucky enough to reboot in airplane mode sometimes which helped once or twice. Or to reload a rom. I just dont know how to fix it? I had my phone warranty replaced due to this issue and it still remains on new phone. I am somwhat pissed myself

Happens to me randomly specially when searching in Map app. Phone starts lagging and I have to reboot. After reboot it shows No entry like sign in status bar. Nothing works, I tried rebooting, reinstalling same rom, new rom, new modem. What works is take out battery and reinsert it. Thought I got a bad phone, but now it seems others have this issue too?
Im just south of chicago and I usually have to download my apps 2 or 3 times to actually get them installed. I noticed that after you choose to download and it spits you back out in to the menu. Reclick the app you just installed if there isno statusbar you are not trully downloading it.

This is the second vibrant that I have had this problem on, So I want to say software, unless I got 2 phones with the same problem. The EDT gps fix makes my gps lovely when I have a data connection. I know that heathen has also made a flashable data fix which would at least stop from having to do a data reset, and reinstalling all apps. Unfortunately the data fix is rom specific and not a universal deal. Anybody with more experience know why many vibrants have this intermittent problem???
Since I unrooted I have had no data drops, but cannot fully unlock the potential of the device, has anyone heard if a way to maintain stable data thru root?
Thanks

Did you try out different modems at all?
I've had the phone for 5 days, and I've gotten about 5 restarts.
It happens when I'm doing something. Playing with ring tones, playing a poker game app...
Just wondering if it's happened to anyone else, and if it's hardware or software related.
EDIT: 9/29/2011
I've had the phone for about 2 weeks now. The past week, I've not had any restarts. Don't know what's changed. I think there was an OTA update about last week. I"ve been using it as much as I had been - web browser, angry birds, email, etc...
Oh, about last week I also re-seated the battery. Don't know if that does anything, since the battery seem like it was seated fine. But someone recommended it. Could just be a fluke.
So, one way or another, the random restarts seem to have solved itself.
Me also
Had mine for about a week and has rebooted at least 5 times. Phone seems to hang and then rebooted.
I am coming from an EVO which never had these problems. Thought about trying a Samsung or another Photon
Yea, just yesterday when I was using my flashlight app for a few minutes. It has mostly happened when I used the led flash as a flashlight. It doesn't matter which app I use, it just restarts sometimes.
And also when I was playing a game today.

Those who don't have random restarts hardly at all...are you installing apps and using the phone fairly heavily?
I'm wondering if this is a hardware of software issue.
Try re-seating your battery and make sure the back is on good.I was having the restart issue and it ended up being that the rep that initially started the phone up didn't put the battery door on correctly.

Exactly. I've only had one random restart, after the OTA, but I chalk it up to the heat wave where I was working. Poor Mo-Pho got up to 119 degrees.
I would also suggest a factory reset and wipe of the internal SD, a lot of times the testing of each phone before they're put in the box can cause issues.

Ive had my phone for about a month, probably had 7 or 8 restarts total since I got it, two in one day during the first week but it seems better after the second OTA update. For the past two weeks I've only had two restarts. Each time it restarted I was playing angry birds and had let the phone got to sleep while in the middle of playing. When I woke it up it restarted.

I have the reboot issue, but I have narrowed it down. DEVS TAKE A LOOK!!
So far I can get a 100% repro of this issue if
1. I am on WIFI for DATA and make or receive a call.
2. then leave WIFI area and attempt to call out, TXT or use 3G data.
3. phone will reboot every time when that occurs.
60% repro of reboot issue with the fallowing.
1. make or receive call with WIFI on but not attached to network.
2. go into WIFI range of a known(not new!) WIFI hotspot and phone attaches to WIFI on it's own.(this will sometimes cause the WIFI, 3G, and phone signal to all appear in the task bar at the same time)
3. make a phone call, txt or turn off WIFI then attempt to use 3G data and phone will reboot.
Also this is VERY IMPORTANT!! The conditions above will not cause the reboot on it's own. If you have data updates off or leave WIFI off all day then you might never see this. Also VERY important if you receive a call when attached to WIFI and then use your phone for data only you will not get the reboot right away it may take upto 30-40 min. Also important, if you attempt to do either repro above via making a phone call you will see the dialer get stuck at "connecting" in the upper left hand side, but it will never go to "connected" and hitting anything on the dialer or the back button will not help only home, but you will notice nothing on the phone will work anymore. This will ultimately lead to a reboot!
Here is the problem as I have trouble shot the living crap out of this and it seem that either the voice/3G radio is locking up or the dialer is crapping out.
Also on a side note that when the dialer is stuck on "connecting" if you force stop the dialer it does nothing, but if you force stop the "dialer storage" it will kill the dialer, but you will still get a reboot at some point after that.
So now we know where to look at for this issue. Can any of the devs look into this as I am not sure where to go from here, but this IS the problem everyone is seeing and can be hardware or software.
Ive searched the forums, googled, factory reset, messed about with *#0011# power save, rebooted/forgot router and I'm STILL having issues with the wifi dropping and reconnecting periodically (maybe once every 10/20 mins?) . Im on BLG8 which is as far as i can tell the latest firmware (im not rooted) for the UK.
Has anyone got a solution to this? The main reason is I use Skype a lot and the call will just drop (obviously) with the wifi drop outs.
No other device has issues with my wifi router.
Any help would be much appreciated
Cheers
Does it make any difference how far you are from the router? Does it always connect fine initially?
I'm having the same issue and i've tried every fix that has been suggested. I dont understand after spending the amount of money i did on this phone that i have to run through the dialer to get it to work properly sometimes. Then other times it still drops out and wont come back on for 5 to 10 minutes. I've changed roms, kernels, and wiped completely i dont know how many times and went back to stock. Still works sometimes and hangs up others. There doesn't seem to be a permanent fix for people lucky enough to have this issue still. My 30 day return is way up and gone so i cant send it back. Samsung cant seem to give me an answer. I'm at a loss for words.

My 30 days was up, it's still been replaced under warranty. I took it to CPW who sent it away, it came back 'fixed' so I asked them to log into their WiFi... of course, they couldn't and the guy said he would order me a new phone but it would need to come from Samsung. My new one has blazing fast WiFi!
i have the same problem. i was hoping a new rom would fix it, but FWIR its busted. i get 2 bars MAX no matter how far i am from teh router. its fast enough, but it drops out constantly.
also my screen is sometimes slow to turn on from sleep.
im on vodaphone if that makes any difference.
Guys... I had a very similar problem with my phone.
First of all WiFi became very unreliable.. like yours. I changed ROM and it still persisted. I even went completely back to stock.. and it still persisted. Dropping out.. no reliable connection etc etc.
Then it started being really weird.. the touchscreen started responding intermittently. Sometimes I couldn't get it to unlock. And this was all on stock.. no root etc.
I was ready to send it back to be repaired.. and I came to the conclusion that there must be something staying the same.. even after a wipe / reflash. Maybe one of the other partitions was corrupt???
Now I'm not clever enough to investigate.. but I did come to the conclusion that a repartition may wipe everything and make it a real fresh install next time.
So I found an appropriate .pit file and stock ROM and used Odin to flash the ROM and partition the phone.
And it is now all fully functioning again.. no WiFi issues at all.

It seems to have improved with the latest JB leak, still every now and then but certainly better - i did a full factory reset + cache wipe in stock recovery (im unrooted etc). Still, would a modified kernel/modem fix this very common issue?
This problem is everywhere it seems.
OK so really weird update: my screen unlock is still a bit slow, but my wifi hasnt dropped for a few hours. i went through all the vodafone crap and updated/ran/configured it all, and now it seems fine. seemed vodafone wanted to verify my phone+sim details but couldnt over the wifi so kept trying to do it over the 3g, but couldnt do it quickly enough so the wifi cut it back out again. I have a headphone amplifier that is very sensitive to mobile phone signals. it beeps 4 seconds before i get a message or phonecall, and "ticked" at me whenever my wifi dropped out. its not ticked in hours.
TL;DR anyone on vodafone, run your "my vodafone" application and configure it all. might fix it.
Mine drops wireless a lot when connected to wireless A networks. It seems stable on wireless N networks. Anyone else notice A networks to be worse?

That seems a little on the warm side, even for stock, if I were you I would try to figure out if an app is being a CPU hog causing it to heat up.
My phone is 40 C tops... There's something definitely wrong here. Do you have a gps running the background? LTE on constantly?Tons of Data being constantly pushed?
Apps are ok. Im on wifi right now, sync is off, cpu usage is about 15% while reading this thread on tapatalk and im hovering about 55 celcius. If its not common then i guess ill call verizon tomorrow
Mine gets the overheating warning fast, well lte all day isn't helping it.
My phone always seemed hotter using the stock ROM. It stays much cooler on AOSP. My CPU will get up to around 70-75C during a stress test but normally under regular conditions it won't get above 55C.
SD Card
Problem: Overheating
A lot of people have reported that the S4 is getting very warm or even hot at times. Most people are experiencing this during movie playback or while gaming. Some had a problem with random apps, during calls, while browsing the web, or while using the camera. A few have experienced an issue while charging. Any smartphone is going to heat up with extensive use and hot weather will have an impact too.
Possible solutions:
It could be a rogue app. Make sure you have the latest updates for all your apps. Fire up the Play Store, tap Menu then My apps, and you should see available Updates at the top right. If you have an up to date app that always seems to cause the problem, then try to find an alternative.
Some people report that media server could be the culprit. Try removing the MicroSD card and backing up all the files onto your computer. Reinsert the card into your S4 and format it. This might solve the problem.
If it is a software problem then an update might solve it. There are reports that Sprint S4 handsets have already received an OTA (over the air) update, but we don’t know what it was for. In any case this solution means waiting.
If your S4 continues to heat up,and you aren’t using it heavily, then it’s possible you have a hardware problem. Contact your retailer, carrier, or Samsung to report the problem and see if you can get a replacement.
This work for me hope for you too

^ I saw that article too and tried removing my SD card, still heated up. Thank you for posting that though. Since this is a corporate phone I called my cell department and asked them about it. They advised that if the phone is still working then not to worry about it. They said they will take care of it if and when damage occurs. That said we will consider this a test. If the phone still lasts a considerable amount of time then we will know this is just a hot phone. If anything else develops I will be sure to update you guys. Thank you for ask the help.
Also according to this 60c is on the warm side but still safe. I know its not our phone, but in regards to thermal properties a chip is a chip right?
