You have to press your menu button in the menu *#197328640# then you can select wifi. It is not a menu item.

turn your phone off then back on and it resets back to default. :cyclops:

does it actually do anything......
i mean if you ran some speed test, did it actually improve the speed??

How did you even get those speeds when the S3 is only supposed to support up to 21mb/s

This just disables sleep mode, doesn't improve performance as much as you think it does.

dead Galaxy Note

Hi every one! Everything was ok with my GNote and for months with ics update. yesterday I tried to reboot it because the battery was empty after long time use. I connected the phone to the charger but nothing happens. I waited a few hours but nothing too. It does not pass to download mode and recovery mode too. I tried the battery on the GNote of my brother and it works and its battery does not help to boot up on my GNote. So the problem is on the phone. What is the solution please?
PS: i don't changed anything on the Gnote since Mounths
Thank you

Just a long shot, but is it a faulty battery connection on your device.
have you tried to flash another gb or ics rom?
Im guessing you run on stock ics, you could be superbricked if you deleted a big file from your phone, deleting big files could trigger the eMMC brick command. Just guessing here so i could be wrong.

Wrong.
Seems to be battery connection problem from your tests as it was said before. If your warranty is not void..should go for SAV.
Sent from my GT-N7000 using xda premium
i'll send it to SAV Later. Thanks for all of you
Have you tried charging your battery in your brothers note, and then placing it in yours? If your phone boots, then its a faulty connector issue.

If it was a faulty battery connection, as seems to be a consensus here, than your phone wouldn't boot at all; yet you say that you can reach Download and Recovery mode.
It's something else.
No i cant reach any mode

i got the 16gb att version....it lags when on energy saver mode besides that its ok. The thing that upset me is half the storage is already used with all the stuff on the phone. It cam with about 8gb free. I am still playing around with it, the battery seems to drain quick but that's normal for a new cell out the box.

its always keeping my phone awake for 3 to 5 hours when im not using it

i do know it, i have been investigating about it without much success.
Mainly i can make it dissapear for half day if i use WIFI, once wifi is enabled the wake lock dissapears when i stop using wifi or do an experiment with it.
but somehow the error comes back once in a while, after a reboot, or after charging it.
no kernel fix it, no Rom fix it, im putting my hopes on CM

i removed fast dormancy and ril-fd is no more (im on crash rom atm where i found a cooked setting to turn off FD).
so this might be related to fast dormancy, i dont want to root this phone yet for certain reasons so i might try switching carriers, maybe it'll help

there are pre-rooted stock roms which are not supposed to increase the flash counter.
And i confirmed it, i toggled FD and the wakelockappeared, changed roms and tried that again, and the WL dissapeared.
But still my battery life sucks though, getting a honami when its out.

honami is the code name for the i1(naming confirmation pending from sony, will be disclosed at IFA or so we hope).
after A LOT of hate which went throught the phone, i updated the arrow rom to 5.1, deactivated FD, and nothing,i was getting 10% in 3 hours, for some reason i dont remember i rebooted the phone, and the darn phone still have the same charge from yesterday te phone have 24 hours of uptime (taking in account i have done some serious undervolt to the phone). i was getting about an hour per % an a half with hangouts and whatsapp freezed and in NO use or just checking the bat.
Not bad but too much work to have a "regulary updated" phone to work properly.
now i dont even know what will happen when i recharge the phone again what kind of behaivor will have this darn non-optimized phone I'll be reporting what happens.

[Q] How do I make my phone faster?

You can't. Network speed/strength depends where on your location?

Yeah reception on my note sucks from home, can't even put my unlimited data to use. Looking at 2mb download .8mb upload.
Coming from driod bionic which had 12mb down 6mb up from a weak coverage area.

Sometimes it depends on the congestion of traffic through that one particular cell tower that you are connected to. To test this as a variable, physically move yourself to another location where you are connected to another tower and run speedtest to compare

Called Verizon and they told me to switch sims and it got a little faster but still not as fast as my note 2. They told me to factory reset but I don't want to reroot and go through that whole process again, but I don't think factory resetting will do anything. I was thinking of downloading setCPU or no frills and just running it on performance and set my minimum clock speeds higher. What do you guys think?

Verizon ticks me off when they mention factory reset. The reason I believe they say that is:
1) it's fast and easy for them
2) they don't have to troubleshoot ur phone
3) they don't have to deal with you
4) most don't know crap about phones anyway
5) ur wasting their time to make more money
6) if you revert back to factory and still have an issue then they replace it. (Again because steps 1-5)

[Q] Alarm When Phone is Off

Ok i keep it straight..
Its my first Android device (The S4.)
Switching from my nokia c7 i've had this issue of alarm not going off when phone's off..
Actually i faced this problem that day when i had only 4% battery left (obviously it wasnt going to last that night)
So i turned off the phone and thought the ALARM would wake me up the next day..( as my nokia always did )
But to my surprise it didnt...
I did search for some solution on xda but no luck..
But then i saw the link of alarm working WITH PHONE OFF on the Rival HTC ONE..(http://forum.xda-developers.com/showthread.php?t=2406083)
So i was wondering whether the devs would be able to make some app..(Or refer me if theres any as i couldnt find one..)
Thanks for your precious time..
Regards.
Me
EDIT : So i was going though some more stuff on this matter and found something relevent..
Like there is a real time clock running on pc (that keeps time even when its off)..
Maybe HTC does use that to make its ONE power on ..
I think some files in the kernel can be edited for some progress on our s4 ( I am completely a noob and have no idea about kernels n all , i just read it somwhere)..
Maybe some real pro can help us out here, by studying htc one's files.. and try to make it work on some other 'SmartPhones'.
+1 to that plenty of time phone nearly dead and would love to do this if possible

The problem is that some 'smartphones" never really turn off.
My Blackberry Storm was one of those and my guess is that the previous phone you had didn't either.
If the phone is in deep sleep mode, then it can wake up.
If on the other hand, it's off, and I mean really off, there is nothing you can do.
The current crop of Android phones turn off; not go into a deep sleep.
Then how can HTC one do it..
I mean it may go to deep sleep..
But can't our s4 go to deep sleep..?

When your screen is off your phone is in deep sleep. At least should be i dont know how they did it but when you turn off android phone its off. No alarm. Maybe they have modified fly mode and altered frequencies for cpu gpu etc to be just enough to ring alarm with almost zero power consumption. But again its not off. I miss that too. Its like where to **** is my charger or hope my alarm rings
Sent from my GT-I9505 using xda app-developers app
With screen off battery goes down by more than 8-10%
I don't think that's deep sleep.. (in deep sleep battery shouldn't drain more than 2-3%..)
Yup if HTC can do that y cant Samsung.. Or other devs..

Dude only 4%,Thats great for you..
Do you use any battery app.. Or its by default..?
I've removed one phone lock app which did save me about 7% drain but still cant get it below 8%..for ( 8-9 hours of sleep )
But i'd still love this alarm feature..

Yes. Software-based. The question is that if a 3rd party app have access to the system to create an "auto on" or if is something that needs to be manage on the OS itself. Maybe with root access?

Maybe some tweaks in the kernel..
I read somewhere that HTC uses some real time alarm clock.. ( I ain't confirm about it though)
Haven't got any developer interested in it yet..
