S4 reboot problem

Hi I received my s4 today but as soon as the screen goes black from none use it just reboots, if I use it its fine but as soon as I put it down for 30 seconds and the screen goes black it reboots. Is it a setting I'm missing or a faulty phone, sorry for the noob question but I'm along time apple user thanks for any help.

At first glance, it sounds like a defective phone that should be returned promptly. However, we should make sure that you are sure you're doing things right. You're not holding the power button down at all, correct? (just pressing it?) And you're saying that after it sleeps, it simply reboots, or it reboots when you try to wake it up?
First try messing with the screen timeout/sleep settings.. I think the default is 2 minutes anyway, so I don't see why it would reset after 30sec.
Next, the battery is charged, right?
Next, try pulling the battery and putting it back in.
Next, try a data format / factory reset. If you return the phone, you'll be forced to do this anyway, so it's worth a shot.
After that, you've got me. Anyone else?

Thanks I have tried all the above but it's still the same, I've had to phone for a replacement but due to limited stock I've got to wait three weeks. Is there any way I can download the original firmware and reflash it.

There are no stock images as of yet, so you are not able to do this currently

Thanks for that the weird thing is I can use the phone for hours with no reboot problems, but as soon as I stop using it, it will turn itself off and reboot.

Yeah, that doesn't sound good and certainly isn't the user experience you are looking for in a brand new flagship phone you dropped a pretty penny on. You could try bringing it into the retail store purchased and see if they can do a swap there. If there are more in stock it shouldn't be an issue. I assume you had it pre-ordered online

When I try to use kies in your above post I get this message 'GT-I9505 does not support initialising, and when I look at my firmware information it says your devices current firmware version is not supported to update firmware via kies.

Samsung has just released the German version of the Firmware (GT-I9505) for kies so hopefully the US AT&T (i337) will be released soon. Check SamMobile's site for firmware updates and to see if they available via kies yet.

Have you tried just doing a factory data reset? You can do it through settings or even stock Samsung recovery I think.

Hi. Since 27th i have the same problem. The phone reboots sporadic. After factoryreset everything ok but tonight the same problem occured again.
Any solution?
Thanks!

If you are not rooted then I would first look at what you may have installed since you got the phone. If you have not installed anything, have not rooted, have not frozen any apps, etc. then I would get in line for a replacement asap.

Do a factory reset. If that doesn't fix it, hope you have a warranty cause it sounds faulty.

Hey.. got this, too. But not with any software upgrade from AT&T!
After Flashing the I9195XXUBML1 i wasn't able to activate my WLAN.. So i flashed back to I9195XXUBMJ7. Now my WLAN works.. but i get this Error message too, that Unified Daemon(EUR) has stopped. Even wipe oder reflash did not make something better :X

Unified daemon (EUR) has stopped
Hi all,
I ran into this issue on my S4 (AT&T i337) when I updated my ROM. In my case it was a result of a dirty flash. The xposed framework was not installed on my phone after the flash, but Wanam was attempting to run. I reinstalled the framework, rebooted and the problem is now gone!
Hopefully this helps someone out.

[Q] HELP! Updated Telus S4 wifi not working

I hastily went for the latest update provided by Telus May 17th 2014 and everything said it worked but my wifi doesn't work (can't turn it on) the button just reverts immediately back to off. I could sure use a little help from the Gurus here on xda developers. I should say that the system was rooted and knox was disabled. I lost root as always after the update but was able to redo it and have it again.System still reports that it is 4.4.2 which it was before the update.

Try to download the firmware again on Sammobile and install that manually, can also try to flash model through recovery might help.

I have a EUR model so I will have to wait. But is the bug that the LG G3 had since the update to Lollipop solved? The bug where the screen goes on every 10 seconds after the battery is fully loaded using a wireless pad? Since the update to lollipop I cant use wireless charging anymore since this is a very anoying bug.

Wouldn't know. This is my first time on Lollipop.

I just updated my D855 SEA model with the latest OTA, did a fully wipe and started fresh. Charged it last night on the wireless charge pad and no such issue.
Cheers

Thanks, @cheetah2k

If this V20B SEA an older version than the current V20E?

I believe so, @twosix but the thing is, it doesn't have much bloat, IMHO.

Did a factory reset yesterday and set back everything with the LG backup feature, but the bug is still present

My SEA/20b version has intermittent weirdness with wireless charging. It often wakes in the night to say its charging slowly. I'm using an LG WCP-700 charging pad.

Guys, for some reason I feel that 20b is better than 20e (had that before the official launch of lollipop for SEA).

after updating via pc suite and checking for another update, it shows two upgrades available with version that is still v20b.
can someone please let me know if they have successfully upgraded their phone with both upgrades?
thanks.

well that didnt go well, it was a two part update to 20b, after the first part installed it got stuck in a boot loop and then second part installed still in boot loop, after install finished it just kept boot looping, i had to put it in recovery mode and do a factory reset, that worked but it loaded up with 10k 4.4.2 kitkat, so pluged it back in and ive just updated back to 20b, think ill leave it there unless somebody wants to try it

Same thing happened to me, except i think i only got the boot loop after the second update.
Did you happen to catch the firmware file name of the second update?

in the box on the screen on the second update it was already showing 10 k 4.4.2, i can only think that the first part of the update rolled it back to kit kat

Reporting after update
Update sucks, a bit laggy, and usage bumped up from 14% to 20% in smart cleaning. And there's really no need for T-action, though quick remote did get its very much needed upgrade.
I think this has some added bloatware to it, guest mode is gone (i mean half-a$$ed), quick memo+ does not activate when pressing its icon from the integrated home button, but I did discover a way to use it.
First, open the quick memo icon (green), close it, then press the shortcut on the home tray, now it works!

does anyone of you know what's the difference between the brightness slider on notification widget having C on it and without C? I cannot understand what's the difference, it seems the same for me.

[Q] note 3 camera issue

I purchased a pre owned Note 3 from C-ex and the camera is not working, when u select camera it is a black screen with the camera icons tho, the icons are not responsive and after a while it says camera is not working. the man in shop where I purchased it from said they believe it worked fine before 4.4.2 update and only stopped working after this update.
anyone have any solutions for this so I can possibly get camera working

I guess it's stock, non rooted and it was updated trough ota ?
A factory reset would be good.

You've got some reading to do. Look for the stickies at the top of forums - usually there's a guide there for how to do basic stuff with your phone. First thing would be to find out how to use Odin (software on your PC) to flash the software for your phone. You can get the latest release for your specific phone from sammobile,com - they have the firmware listed. You will need to sign up but it's free.
You will need to DL the samsung USB drivers and install them on your PC.
Then you use Download mode to connect your phone to the computer and flash the firmware. When it's finished you have a as-new phone set up.
If the camera doesn't work then there is something wrong with it.
Feel free to ask, but make sure you do your research. XDA'ers help them who helps themselves.
