Hi Samsung! Please, if a Samsung representative is reading this - please do something to help. Please speak to a higher up technical programmer, software engineer and hardware engineer. Please get to work on this to find out how to correct this problem. This problem is going on for years with several of your phones. The problem? The phone lags, freezes and reboots. Or does not reboot. The phone turns off as if the battery has died when the battery has 20-30% left. Several times mine turned off when my battery had 49% left!
It may pop up with a message with the green Android man saying do not turn device off while we download... I will lay out the general problem. But if you do a search on this forum AND on Google - for the words Samsung Rebooting or Note 4 rebooting - you will find hundreds or thousands of people complaining about this exact same problem. Yet Samsung has not done anything to correct it. Many people are saying that this problem is engineered into the phone by Samsung in order to get the users to upgrade.
I'm on my second Note 4. 7 months ago my Note 4 just started freezing and rebooting. Rebooting in a loop. Sometimes the phone acts dead and does not restart. We have to do all kinds of tricks to get it to start up.
Most people blame this on the software updates. I had the phone replaced by Sprint. It worked great. This time I refused to do any software updates. 7 months went by and again last week one morning out of the blue, it started freezing and rebooting. Same exact problem. This time I did not do any software updating so the updates was not the problem. When the problem started this time I had not done anything to the phone. I had not loaded any new apps. I called Samsung and the representative doesn't know anything about it. I told her to search the Community forums. She asked me to do the standard checks again.
No - removing the SD card does not fix it.
No - clearing the Cache does not fix it.
No - factory resetting does not fix it.
No - going to Best Buy to have them reflash the software does not fix it.
No - new batteries do not fix it.
No - keeping the phone plugged in does not fix it.
No - the problem happens while running in Safe Mode also.
I tried many other ideas as well. No help.
This is the last chance. I am hoping to replace the phone again. If this happens again then I will be out and I will no longer buy Samsung. I feel this is a serious problem that Samsung is not interested in correcting. Please read all the forums. I am not the only person saying that. Most people with this complaint are saying they will not buy Samsung again. When my Note 4 works I very much like the phone. I'M VERY HAPPY WITH IT. But I need a reliable phone that does not reboot when I'm on a call or doing something. Often I pick up the phone to make a call to find out that it is trying to reboot itself again and is stuck in a reboot loop. I will have to consider LG, or Pixel or Nexus or even Iphone (ugh). I just started getting information about a new phone competing with the S8 - Essentials PH-1. I'm not looking to switch. I want to remain with Samsung with my Note 4. Does Samsung want me to stay with them? I'm not convinced.
This phone is a $700+ phone. I've only had the first one for 7 months and the replacement for 7 months. I'm not willing to pay this kind of money for an another phone. Totally unreliable for a very expensive price.
This problem is not limited to the Note 4. I've spent a few hours reading these forums looking for help. Note 5 users, Note 7 users have the same complaints. Though the Note 4 seems to have the bulk. I just saw a post on Samsung's Community Forum with someone having the exact same complaint on the brand new Galaxy S8!
I personally think that this is not a software problem because when the problem started again last week, I had not made any software changes to my phone including - I had not downloaded any apps. I had not done any software updates since I got the phone. The refurb phone replacement that I received was already on Android 6.0.1. I left it where it was and did not update it. When I woke up one morning and turned on my phone, the phone froze and rebooted. It then rebooted itself countless times that day. I went to the Sprint store and the man says he knows the problem. But he is obligated to go through a series of testing even though he knows it will not fix it. I believe that there is a hardware component or circuitry in the phone that failed. Maybe it was overheated or burned something out. There's an app called WAKE LOCK. I found out about this app from a forum on a Google search for Note 4 rebooting. Look for it in the APP Store and look at the comments to see how many Samsung users are using this. I loaded this app on to the phone and set it for level 4 - Partial Wake Lock. As long as that is running, it does about an 80% good job of keeping the phone from rebooting. It does it by not allowing the CPU to rest and fall in to sleep mode. But when I change batteries and try to reboot - either it will just not restart. Or it will get into a rebooting loop. Or it will sit on the opening SAMSUNG GALAXY NOTE 4 startup screen for a VERY long time. Once I get it to start up and the WAKE LOCK app starts it stays on for a longer time before rebooting. But it may turn off (without rebooting) even when the battery has plenty of power left.
SAMSUNG PLEASE - PLEASE FIND AND SPEAK TO THE RIGHT TECHINICANS IN THE COMPANY. PLEASE FIND OUT HOW TO CORRECT THIS PROBLEM. PLEASE SUPPORT YOUR CUSTOMERS AND KEEP THEM HAPPY. OTHERWISE IN THIS AUTOMATED SOCIAL MEDIA WORLD, WORD WILL GET OUT ABOUT THESE PROBLEMS AND CREATE ANOTHER PUBLIC IMAGE PROBLEM FOR SAMSUNG. MY FRIENDS KNOW HOW FRUSTRATED I AM AND HOW MUCH TROUBLE I HAVE GONE THROUGH TO GET THIS FIXED - UNSUCCESSFULLY.
I installed echoe rom pure Note 4 V47 and with synapse I set the max cpu clock to 2.0 GHz and governor to alucard.
I think the freeze happens because the high drain cpu current in complex operation, like shot a photo, the cpu voltage drop too low. With underclock the cpu current it's a bit more low and the cpu voltage do not drop too much.
With android 5 the max benchmak on antutu was about 50'000 while in android 6 the max benchmak antutu is 75'000 on my note4 with echoe rom. The increased performance cause high current drain from battery and maybe the power circuitry is not adequate.
I too have had the Note 4 for about 2 years now and two months ago it started constant rebooting. The only way I've found to counter it was to use Wake Lock......in Partial Wake mode.
Drains the battery faster but phone operates normally.
I love the phone but this should never happen on an expensive device.
Samsung seems entirely oblivious to the problem which is widespread.
For that reason I will never buy a Samsung product again.
It is outrageous that Samsung created this problem with a software update and thousands of phones have rebooting issues and they have done nothing. Trying WakeLock. Goodbye to Samsung when this phone crap out.
Wondering if they will leave this post in here. If I don't have a warranty, why not go to a custom ROM? To get the Note funationality they would still be based on Samsung for a newer phone. Might still have the same problem
They left the post about a custom ROM. While I look into that more (noob to the processs), I installed Wakelock like many threads suggest. Using partial wakelock and it sems to be much more stable. I have had one time in 48 hours that it seemed to freeze, but that could have been the app I was using and unrelated. It went on working after a couple of seconds. As those threads described, it does cost some battery life but at least I can use the phone when I want to know instead of spending time waiting for a reboot.
After numerous attempts to fix this problem and nothing worked. I decided that the Nugget operating system was the issue. I downloaded a app to scan my phone. The app would scan for operating systems that would work on note 5. Results was nugget failed. Doesn't tell why.
I decided to revert back to marshmallow os. Downloaded the needed firmware file, Odin. It worked out. Phone is back to normal.
Exact same problem started on my Note 4 about 2 weeks ago. Bought new battery...no change. I did the update in early August...might have started the problem. Thanks for the excellent post. It describes all my issues.
