I have a note 2. It's i317 to be exact. My issue is really weird. When I turn it on it will freeze randomly.... during boot or just whenever. This kept happening. So I put it up to the air conditioning in my car and it never froze. I could use it all I want as long as I kept it cool like up to my AC in my car. This tells me it's a heat issue. If it freezes and I quickly blast AC on it it suddenly starts responding again..... but only if I'm quick. ... if not I gotta pull the battery, cool it for a bit then I can boot it again. The phone doesn't even get that hot when it freezes. ... probly warm at best..... any idea what could cause this? I'm running stock 4.4.2 unrooted. This also happened on 4.3 ..... I tried resetting. How do I fix this? ??
Root it and disable DVFS using wanam xposed.

I've had this fault for nearly two weeks now where the phone will randomly shutdown and when restarted will immediately shutdown again. The only thing that will solve it, temporarily, is to remove the back cover and disconnect and reconnect the battery. After this the phone will start first time.
Anyone else experienced this? Would a new battery solve it? (Battery life is fine at the moment so maybe not this?)
This has happened while running both 4.2.2 and 4.3 My phone isn't unlocked or rooted, completely stock.
Any help much appreciated.
seems as your power button might be getting "stuck" pushed in. that would explain random shutdowns(pushing the button in for 10 seconds force shuts down the phone) and boot up.
That would cause the effects I'm seeing but when trying to start the phone it always "feels" like its working properly. I'll keep it in mind for the next time it happens though.
Never had this happened to me b4. Removing battery wont help either. Tried diff battery and power cable. Its just dead. Soft reseting wont work either
Any ways to fix this myself? Is it the power supply?
I have the same problem, I was downloading the stock firmware on my note 4 while charging, I went to check if it was done downloading but it was frozen, I couldn't get to the lock screen just a black screen with the red notification light, I removed the battery but since then it won't turn on nor charge. I know it's not the battery cuz it works fine on another n4. The weird thing is that I was also downloding the same file on my computer and it was frozen too it didn't finish the download just like my phone,.
This is the first time that something like this happened to me, it wasn't over heating or anything so I have no idea why it won't turn on.
The title says it all. For extra information:
So I got the battery full using universal direct battery charger and put it back. Switching it on without the charger plugged in won't work but switching it on with a charger plugged in does. You can even unplugged it after that vibration when turning on. That means, it's not the battery... you can even see the battery's full after booting successfully.
Not only that, with or without the charger, the S4 would heat up so much. No it's not the apps, even in safe mode or just while booting it would start to heat up. It wouldn't stop heating.
At first I thought the problem was the switch cause it won't turn on. Then I figured out it would turn on... but with the charger plugged.
Hmmm, any idea what cause it? It just happen all of a sudden one day. I'm thinking that, even if the switch or the port looks fine they may be the cause. Short-circuit I guess. Or I don't know, just my wild guess. If you experienced this one before, please share you experience and how you fixed it.
I'll add the edit I made on my reply here to make it easier to read.
EDIT: The heat is coming from the upper right area. Very close to where the switch is and sd card slot. Do you think it's the switch? If it's the switch, it's working well. No sudden reboots or shutdown due to the button acting like it's pressed when it's not, etc etc
EDIT: FIXED​
Flashed Albe95's LolliRom http://forum.xda-developers.com/galaxy-s4/i9505-develop/rom-albe95-lollirom-official-1-0-t3049564 and also flashed Imperium Kernel (afterwards... because I thought I already did -_- )
At first I thought I would switch ROM to see if it's really the ROM that caused my problem (Stock with AEL kernel).
I downloaded Albe95's ROM and it took some time before it really boot successfully. On the thread it says that it would after 15mins, but mine after 15mins is still not booting. I flashed many times thinking that I made a mistake, like I forgot to wipe, etc etc.
The overheat problem was still there while it boots. It gets really really hot. I thought it is really a hardware problem now, I flashed a new ROM and therefore the kernel was changed, and if it was changed and it still has that problem my conclusion was right.
BUT...
I put it in the freezer to battle the heat. When I took it from the freezer, the phone's off. I thought the coldness what made it turned off. I took it, charged, and turned it on. And when it turned on after plugging it in... the battery's empty. It was around 50% when I decided to boot again and wait.
While it is still cold, I tried to turn it on again and wait now this time for it to boot.
Albe95 said it would take around 15mins only, but mine did boot past 15 mins. Can't blame me why I thought it's stuck on bootloop for many times. Now I'm thinking if I have only given Imperium ROM a chance... HAHAHAHA too lazy to flash and wait for a long time again.
Please hit thanks if I helped someone in the future with these issues.
what s4 model, rom and kernel do you have ? any mods ?
the battery could still be the problem. can you test it with another one, a friends maybe ?
Maybe a short circuit by sweat water that got into the phone. Open it up, take the board and other other easily removable components out and clean them with Isoprophyl(cleaning alcohol) and a new/clean soft brush, reassemble and see if it helped.

This might do. Did not thought of this.
It's more on hardware I guess... Not kernel or ROM problem. Or, ok fine, just to be sure I'll try to flash Albe95 ROM. I am on Stock before and accidentally wiped the system partition also while trying to factory reset via recovery instead of data, cache, and dalvik only. Even without the ROM, it overheats very much.

Hey , I have a rooted Zuk Z1 for almost 2 months now, this week he began doing weird stuff like:
- charging really slow with no led light on when charging, if the phone is turned off then it just moves between showing battery to zuk logo with a few seconds in between. if connecting the cable to a computer it wont have that problem.
-Another thing that was earlier but doesn't occur now for some reason is the phone turning on when i plugged it in, when this was happening another thing that happened was that sometimes the phone just booted up and was fine for a few seconds to a few minutes and then just rebooted for no reason and this kept going unless i'd force shut it regular didn't work.
What do you recommend me to do?
Thanks.
Do you have some 'crazy' apps installed? Then uninstall and check again... If that doesn't work, flash the phone to stock...

Should I just flash cm13 onto it ?
Let me explain what happened: I was using the phone as normal, but suddenly it started to reboot itself, and with every reboot it was losing some battery until the point it lost all the energy, and now when I try to charge it, the only thing I get is the battery animation starting and suddenly disappearing, like a bootloop. Same situation when I try to boot into Safe Mode or Recovery Mode. But I was able to boot into download mode, so I tried to flash the stock firmware again both through Smart Switch and ODIN, but I got the same results. And also, this only happens if I have the phone connected to the PC or the charger. If I try to turn it on while disconnected, it doesn't do anything. What can I do???
Update: Well, now it reaches the Samsung logo but it get stuck in a bootloop. I 'm also able to boot to the recovery, but I'm not really sure of what can I do from there
I'm having similar issues!
Upon further investigation, I discovered some pocket lint stuffed in the bottom of the MicroUSB-port. A toothpick was enough to get it out. Still having issues with "mmc_read" failure, booting and long response times, but at least it charges reliably now. Will flash updated recovery/kernel/ROM as it has been a while - fingers crossed this will help.
I'm thinking the root cause of our issues might be different, but check your USB-port if you haven't already.
For my next phone I will consider integrated port covers, like the Xperia series.
I bid you good luck fixing your problem. Would'nt mind knowing what the root cause of your problem is if you find out.
The phone is alive again! The problem was the battery, I just replaced it and the phone booted as normal

Thanks for the update. Just out of curiosity. Was the bad battery a little bit puffy. On my note 3 I could tell by feeling and looking at it from the edge. Battery going bad starts to Puff up in the middle.
