Out of the blue, my S4 has started running hot (very warm to the touch) on occasion. Also, moving around screens, typing, etc. is extremely slow. Battery drain significant as well. The only thing that has changed is that TWC installed a new router & the phone now jumps back & forth between wireless & mobile. Ideas?

Are u on custom software? Custom kernel? Try running just on mobile I've heard s4 doesn't agree with some routers
Stock ROM. Heard something similar but it used to do the same thing every so often with my old router. Weird.

ya sounds very strange i havent ever had a problem with heat, i run goldeye with ael kernel and get 3-4 hours of screen time. also rarely use wifi as i have an unlimited data plan.
hopefuly its not a sign of hardware failure
I'm actually leaning towards hardware issues as the wireless problem is getting better. I'm due for a new phone anyway.

Last week when the Onavo data monitor app appeared prominently placed on the market home screen I gave it a try.
Unfortunately it created a very annoying bug on my phone running JVU and Semaphore 2.5:
whenever my phone looses it's wifi connection for any reason it will not recognize and connect to available wifi anymore even if placed directly near the router with full signal strength!
The only way to get it connected again is switching wifi off and then on again...
I already uninstalled the app and did a factory reset but nothing changed. Probably it messed up some system files that don't get touched during factory reset.
As I'm in vacation now and don't have my data cable with me to flash a fresh firmware, is there any way to resolve this issue in other means?
Sent from my GT-I9000 using Tapatalk
Nobody here with any idea how to resolve this? It's really annoying as even battery consumption goes up very much when the phone looses wifi and auto connects to 3g.
Sent from my GT-I9000 using Tapatalk
I have no idea about your problem. I also have just installed Onavo on JVU firmware for a couple days, but everything is still ok....
So, I'm thinking the cause is from your router!! Why don't you try another wifi network?
Good luck!! ^^

Thanks for your answer! It doesn't depend on my router. As I said I'm in vacation right now and therefor using many different available hotspots, it happens on all of them... :-(

Any issues with battery drain and onavo? Cause it was sucking mine dry!! I thought it was semaphore's fault (i'm on icssgs 4.2) until i figure it out and uninstalled it. Now it is Almost as prior installing onavo. I have a feeling that it left some garbage behind though.
It definitely left some garbage behind and this thread is about to find out how to get rid of it.
Battery drain was and unfortunately still is very high on my device thanks to the non desired 3g connection instead of wifi...
Sent from my GT-I9000 using Tapatalk
Try to flash a new kernel again. It may help you updating some files that control wifi.
I used onavo for couple of days, battery drains. Its functions already in ICS roms, Less but good.

just joking hahahaha
I agree about the Wifi. In areas where Wifi is weaker, my iPod Touch performs far better than the Note in connecting
Same issue with me from past two days of usage.
Which version of OS are you using as mine is DDLA1(Unrooted) and I am facing the same issue, I can say this because I have used older firmware version(DDKL1) earlier that was rooted and wifi was excellent.
Never had this problem with all the version I went through. Now I'm on stock rooted LB1

I agree completely. The Notes wifi is quite weak. Can a new modem improve this?
Sent from my superior GT-N7000 using Tapatalk
the wifi signal is comapriably slower than my old hd2, side by side they are both connected via n signal to the router, note is showing 52mb and the hd2 running android is showing 58mb
I get much better connection on the other side of my house than any previous phone or tablet. I must say that even a couple of metres from the router I can get only a couple of 'bars', but download is still very fast.

Do a search (not being mean/rude, just not at a computer to find it for you) about WiFi on the Note in either this or the Q&A section. I read about a month ago that there's a text file that contains the authorized WiFi bands for your country, and since there's no US ROM the bands listed are incorrect. Of course you have to be rooted to change it (which you are), but I'm not so just living with G.

I rooted my device yesterday and flashed AbyssNote Kernel 4.2 and Wifi seems to work fine.
i also got this wifi problems, the htc desire hd got a much better signal
This is a big issue with my Note too. Sometimes signal will be showing aa strong, but then I get message....cannot connect to the server. Compared it to my s2, and the s2 had no problems making a connection.

I just got a gs4 and am coming from the gs3. Does this phone run hot normally? Seemed warm on stock and hotter once I tried to install the freegs4 ROM. Even shut down twice.
Edit: flashed a different ROM and kernel and am all good.

Not true on my part. I've flashed stock deodexed MF9 rom with Stock MF9, Agats, and Ktoonz kernel. All resulted in the phone heating up and shutting down on its own.

So I have tried 4 different ROMs and 3 different kernels and the heat issue keeps happening. Right now I was using the latest Venum ROM and the ktoonz kernel and the phone shut off due to the heat. Stupid phone, I just got it on Sunday. Never had this issue on my epic or e4gt or gs3.

The only kernel adjustments were to the governor and scheduler (using smartass and sio, no alterations to either). I just tried using the rescan media disabler apk to see if maybe my media was causing the phone to run hot. It seemed to be the only thing going in the background.

Usually the heat starts when I am using the phone, which is usually browsing the internet or reading up on sports news. Screen off or charging I have been OK so far. As far as the battery, it appears to be in good physical condition. I also have 2 OEM batteries by Anker that experience the same issue. So far so good, though - been using the phone moderately since the last shut down earlier today and it seems ok at this moment.

if it heats up really bad again try underclocking a step and see if that helps.....phone might be getting hot because your chip is poorly coated and the higher frequiencies are heating it up enough to shut the device down. you may have to underclock by one or 2 steps to ensure its not a consistent issue.....worth a shot anyways. unless you do high graphic gaming and multitask with 8 apps at once your really dont need the higher clock speeds anyways.

Good idea, hopefully I won't need to! Appreciate the feedback.
If you just got this phone Friday then I would return to stock, run triangle away and exchange it. What you describe isn't normal, why take a chance and get stuck with a bad phone when you are within the exchange window.

Try the stock kernel and rom and if it still get hot take it back. Try stock kernel it works man the others just cause me trouble.

Thanks all. I loaded up the latest Sac ROM and ktoonz kernwl, but disabled media scanner. No more hot issues. I guess it running like crazy in the background caused the battery to commit suicide.

Seriously guys, your S4 doesn't heat up at all???
I'm back to 100% stock everything (kernel, rom) and running this for a couple weeks. I've completed several factory resets and whatnot as well through those weeks. I know my install was clean as could be.
Now, my phone gets hot at seemingly random times. sometimes playing games, for sure while navigating with GPS and sometimes when its just sitting there. I monitor things with Better Battery Stats and keep an eye on the CPU Spy. I'm achieving deep sleep most often. Some of this is caused by the god awful Sprint service here and the constant search for signal, but I was hoping that this wouldn't get as hot as the S3.
so, should I seek a refurb from Sprint? I have the insurance. I am just afraid that a refurb would do me no better.
My biggest gripes are heating up occasionally, WiFi disconnect issues. I hope 4.3 can help some of these.
Hey guys I've been having horrible 4g and connection issue for a while on all roms even stock. YouTube is horrible and most things won't load or they take forever. My wife's s4 and daughters note 2 are fine and when they have strong 4g I get 3g. Any ideas.

I have an SM-N900V as well. I was having fits with 4G and wifi. My phone is rooted via vroot. I thought that might be the issue. I did a factory reset and did not restore my apps. I found the phone is still rooted but my connections issues were gone. I started recovering my apps via new installations. I haven't recovered them all btw. I had a ****load I didn't need. I do need an ad blocker and the only one that really worked was ad vanish pro. AVP caused the wifi and 4G problems. I can load it but as soon as I start it and load an affected app, down goes the wifi. I hope this helps and leads to further experiments. We need an ad killer that doesn't screw up the connections. AVP worked fine on my S3 until 4.3 was pushed out.
Hi,
Ive just bought a brand new Nexus 10 and its doing really wierd things.
After updating to Android 4.4.4 i kept getting kicked off and the device would go to the lock screen. Additionally the screen would do strange things when running Chrome like going totally black with a white ring in the center of the screen.
Also text doesnt seem to display properly at times; i have now downgraded back to version 4.2 which seems to have got some stability back howver text is still broken on occassion.... See attached.
Its really odd as i have a Nexus 7 mkII which ultra stable.
Could this be hw related or simply is the rom simply this buggy?
Thanks for any ideas.

Ok so I updated to 4.3 and the machine seems to be stable minus the occasional logout when opening Chrome.... However text still has problems displaying; also as with Android 4.2 it seems the wifi kept disconnecting every few minutes. Since the AP being used was the spare wifi card in my Linux HTPC it migt have something to do with the Intel Centrino card at the other end. I have a spare 3com AP which I will try and if not I also have a spare Cisco wireless router which I can also hookup.....
Other then that I dont know???

Have you tried a complete wipe (flashing the factory image and doing a data wipe/factory reset afterwards)? Not sure if that's what you did when you downgraded. I would think a 100% fresh start would help.
Yep I did... Sorry if wasnt clear. I even reformatted the partitions.....
I think what bothers me the most is the incomplete text...... When downgrading I got the stock rom from Google directly.
Also something funky is the screen seems to slightly flicker when running the Plex app. This could just be an app thing though as everything else is fine.

Boy. This is a real head scratcher. I've never heard of this before. It would be one thing if the screen was static, which would usually indicate a loose ribbon connection. Since you've already successfully flashed the factory image, I don't think it would be software related. But I can't think of any hardware issue that would cause this either.

Ok good news.... Using my spare Cisco wireless router I got stability on the wifi
I'm just thinking that maybe the issue could be something to do with the graphics chip??
Of course if I dont need to i really dont want to but if it isnt a software bug and the issue is hw related perhaps I should just contact the place where I bought it and get it replaced???

Hi,
It is really bugging me, quite a weird issue. I believe it can be surely a defective unit, after all you flashed a stock ROM wiping completely and problems still persists.
I recommend you contacting the place you bought it. Hope you can get a replacement .
