I had the same problems explained here in this post. I own two Galaxy Note 4 and had the very same problems.
NOTHING will solve the problem on your Note 4. You can use Wake Lock, your phone will work well, but if you have to restart it it may not come until you put it in freezer for 10 minutes, which is stupid of course.
I tried all solutions exposed on this thread and NOTHING solved it. I even installed the ROM Resurrection Remix (Oreo version and others) and i had the same problems.
I can assure you that it is not a Software problem. It is a Hardware Problem caused probably by an Update by Samsung. I believe it is the Mobo.
Idk if Samsung did this Update on purpose or not, but they breake the phone down. The fact that they dont care about us shows the very bad after sales service they have. We payed over 700 bucks for a phone that didnt even last 4 years!
IMO Samsung expect us to buy a new phone every X years. Today it is our Galaxy Note 4, but in 5 years will be the same with the Galaxy Note 9 and so on...
Personally i will never ever buy a smartphone from Samsung anymore.
In other words:
Bye bye Samsung------->Hello Xiaomi Redmi Note 5 :-) (at least this one is not expensive)
Just a hint and further confirmation: I do assure everyone here in this thread, with 100% certainty, that this is a pure software issue. If you manage to downgrade your phone to Lollipop 5.1.1 CPD4 release, it will WORK WITHOUT ANY REBOOTING ISSUES or instabilities, only make a hard reset before and after just to make sure no residual files are remaining from 6.0.1. That's it! I did it, and I hope i can do it for you guys.
Just an idea: if it happens that you're travelling down to Egypt (Cairo), send me a message here and I will be very pleased to meet you and fix it in few minutes.
Any chance you could lay out the exact process for doing the rollback?
My phone is a T Mobile unlocked phone....will I be ABLE to roll back?
I have alreayd moved on to a new phone (Moto G5 Plus) but would like to have this one as a backup and not have to throw it out.
I've had my note 4 for 3 years never had a problem with until now it shuts off its hard to get to come back and when it does they android guy pop's up saying download failed or system reboot failed my phone has service I just don't want to do with it
Upon collecting my repaired Note4 (the Samsung Premium Support Center put in a new motherboard for 285 Euro), I turned it on, and the screen went black with odd colored stripes on random locations. Carefull inspection showed that the screen had been broken. So, the Samsung Premium Support Center put in a new motherboard, but broke the screen in the process. They won't make me pay for replacing the screen, but I have to wait for another couple of days. They did give me a replacement phone this time though.
I asked the technicians of two Samsung Premium Support Centers about this issue. Both technicians confirmed (off the record though) that there were "quite some" Note4's with this issue, and yes, more Note4's than any other device.
I'll get 3 months of warranty on this reparation. I'll have a Note4 with a brand new motherboard and a brand new screen. Anyone interested in buying my Note4? You'll get it for only 400 euro! I'll never buy Samsung again!
Not much else for you to do IMHO.....abandon Samsung.
I have a Note 4 sitting in a box, unusable after only 2 years.......
What is so amazing here is that there can be so many of us complaining about the same thing yet Samsung IGNORES us and says "too bad, so sad, it's on you"........and that they continue to send me emails touting their products.
I just got an email ad the other day asking if I wanted to see the new galaxy.....LOL
I will never buy another samsung ANYTHING again.
I was just in the market for a dishwasher and the salesmean offered me a good deal on a samsung.....I said absolutely not.
Here is a thought...if every one in this thread and all the OTHER similar threads visited Samsung's FB pages and posted their experiences, maybe Samsung would listen.
They have a mobile page, an electronics page and a general page......and if you look thru them, others are having issues there too.
Thought this common problem might have something to do with the Fast Charging option so I turned it off. Nope it's still fast charging and heating up the battery. But WOW after reading this post and all the following comments, I've now realised that I will never buy another samsung product ever again. Same problems here, on my third note 4 now. what a waist of my hard earned money. Adios SAMSUNG !!!
