I also changed the battery. Same problem.

I think I am doing something wrong (I have around 120 apps installed) with the apps or with the gsm signal. For the beginning I intended just to do some tweaks on the official rom (remove bloatware mostly). I tried with package disabler, not much of a success.
[Galaxy Note 4 General] shaggyskunk:
You could install Wakelock Detector on your phone - You'll have to Grant some permissions with adb to get it to work on stock Samsung - Also Better Battery Stats (also requires adb commands) app - Both will help you to get an idea as to which apps are killing your battery - But I can tell you that apps like G+ Chrome Flipboard are just a few of the apps that are constantly running in the Background unless you can stop them from running in the Background & continuously refreshing your battery life will suffer.

[Galaxy Note 4 General] ionelm:
Thank you! I used before wakelock detector (always pointing me on Google app direction). I installed also Better Battery Stats and I will wait o see any results.

It looks like also the Doze app is doing something.

Have you rooted your phone?

[Galaxy Note 4 General] ionelm:
No, I haven't rooted yet. I am still working with the adb permissions.
[Galaxy Note 4 General] shaggyskunk:
Trust me - Apps that are constantly refreshing and running in the Background are more of a problem than Google - One of the great things about AOSP Roms is that most include Privacy Guard which allows you to Stop apps from waking or keeping your device awake.

[Galaxy Note 4 General] ionelm:
OK! So it looks like an AOSP Rom is something that will fit me. Do you have a link to the version for the canadian version of note 4?
[Galaxy Note 4 General] shaggyskunk:
There's a few Roms available - None seem to have been updated recently - You can Flash any of the Roms that are available for T-mobile on your SM-N910W8 - Roms that are listed for trltexx will NOT work for you - But trltetmo - will - Flash the latest version of TWRP 3.1.1-0 for trltecan from Twrp.me with Odin 3.12.3 or later - Download the Rom & Open Gapps arm 7.1 (I recommend Open Gapps Nano Package)

Here's some Roms available on AFH I'll edit this post & add a couple more.

https://androidfilehost.com/?w=files&flid=179146

Here's a couple more - The Dev The Br0ken isn't developing the Roms on this thread any longer (he's moved on to different devices) But try AICP & Resurrection Remix from this Thread

https://xdaforums.com/showthread.php?p=68115024

***IMPORTANT***!!

After you Flash TWRP img.tar with Odin 3.12.3 - MAKE SURE that you Make a Nandroid of your current Rom!!

You will also want to Download SuperSU v2.82 Stable to your external sd card - Same with the Roms & Gapps.

When you Flash a Rom - Boot into TWRP 3.1.1-0 and Factory Reset - Advanced in TWRP 3.1.1-0 - Manually Wipe System - Data and Caches - Flash Rom and Gapps 7.1 - Flash SuperSU v2.82 - Reboot and Setup your device.

I haven't really found any of the AOSP ROMs to have any better battery life than stock but I do like them a whole lot more. I just flashed back to stock actually from the latest Resurrection Remix trltexx version as battery was terrible for me. Every now and then my phone would just heat up and chew through my last 30/40% battery in 20 or 30 minutes. Never could determine what was going on. Otherwise the ROM ran pretty well.

I would start with rooting and debloating but make sure to grab a nadroid backup first, you might accidentally freeze or delete a needed file. Getting TWRP and root is pretty straightforward and shaggy has lead you down the right path.
[Galaxy Note 4 General] shaggyskunk:
BTW - You should probably also have the latest Stock Firmware downloaded to your pc - Just in case you need / want to Odin to Stock - You can find it at sammobile.com - Just search for your Device and Carrier ;)
[Galaxy Note 4 General] mystic74:
Battery issues might be because of your cell coverage too.

If you have a very bad coverage at home or at your workplace, this may kill your battery as well.

If this is the case you may consider changing the carrier or getting a micro cell tower.
[Galaxy Note 4 General] ionelm:
I read somewhere that the custom ROMs don't do much to the battery life and that is my main concern. I am still looking for the solution with the original rom rooted and debloated. For the time being I tried to leave the phone over night on airplane mode (only with wi fi on) Doze and Greenify installed (Doze with Gmail permission)and still drained 10 % of the battery. Today I'll try the full airplane mode.

The results from better battery stats and gsam (full) are irelevant. They mostly tell me that the Android System and Android OS are the main source for drain.

Just getting a Canada note 4 next week

And I'm looking for advice on the best marshmallow debloated oem Rom for it.

I'm used to very debloated roms with just about everything extra removed including Google play and all the Samsung apps.

As I understand it the Canadian note 4 910w8 is compatible with the T-Mobile variant. Are there other varieties that work with after flashing kernels? Or simple fixes?

I'm upgrading from a note 3 mainly because of the zero lemon case the note 4 is coming with.

I am having problem with Note 4 Camera not focusing properly on objects. I disabled ever other mode. Basically this happen when trying to take close pictures within a distance of 5"-10".
[Galaxy Note 4 General] nutpants:
I'm not sure about the note 4 but the s5 had a camera glitch that required you to clear cache on the camera app constantly to keep it focusing correctly.

A few Note 4 questions

Hello all,

I've just bought a Note 4 and I have a few questions about the phone's functions.

- Can I access the settings (by swiping down on the notification bar) w/o having to unlock the phone (like some other phones can) ?

- Does this phone have Air wave gestures -I think that's what they're called- like the Note 3 had (browsing pics w/o touching the screen....) ? Some people say yes, some say no. I couldn't find that in the settings like my Note 3 had it.

- When entering a contact's name, the characters we can enter are too few I think (can't put a person's full last name...). Anyway to change that? Also, some phone allow you to add other info (not just email) about the contact and I don't see this in the Note 4.

I appreciate any replies.

[Galaxy Note 4 General] Electroman365:
Wow ! So the forum went dead at my post !

Anyway, I guess no ability to access the settings by swiping down from a locked screen (unless I use a 3rd party launcher) and from what I read this is a security thing ! I guess I can live with that.

I figured out the short characters allowed for a contact's name, but still can't find anything about "air wave" gestures like the Note 3. So, anyone has any word on that, if any one still reads the posts ?
[Galaxy Note 4 General] flyjazz:
Has anyone flashed the Puerto Rico update from September 2017 version N910W8VLS1DQH2 ? Seems none of the Canadian operators pushed the security update to their users. It apparently has some battery enhancements and other minor improvements.
[Galaxy Note 4 General] sefrcoko:
I flashed the latest Puerto Rico version (whichever it was at that time) about two months ago on my N910W8 with Bell...upgraded my phone since then though, and gave it to a family member to use for now. Phone worked well with that FW, but I did have to disable or uninstall a few extra Claro apps and games. Also had to switch to English during initial setup :)
[Galaxy Note 4 General] flyjazz:
Would you say it's any more bloated than Bell's version. Having said that, I wonder if I flashed the Puerto Rico version and afterwards changed the CSC to Rogers using *#272*IEMI# would it retain the update? I don't see any reason why it wouldn't.

Edit: I realized afterwards that the Puerto Rican firmware probably doesn't have the option to change the CSC to a Canadian wireless provider.
[Galaxy Note 4 General] sefrcoko:
Just a little more bloat/branding than Bell, but not much. A few games, a few Claro apps, and a Claro boot screen (maybe a Claro shutdown screen too), whereas Bell only had a few Bell apps and that was about it.

Hmm not sure about the CSC. I haven't really messed with it too much in the past, so I can't say for certain. What you want to do makes sense, but I could be missing something :)
[Galaxy Note 4 General] flyjazz:
Thank you for the insight. I edited my previous post in regards to the CSC. I'm not a fan of carrier branded boot screens, perhaps I'll wait to see if one of the Canadian wireless carriers pushes the update, I won't hold my breath.
[Galaxy Note 4 General] sefrcoko:
No problem. If rooted you can always change boot animation or debloat as needed too, if you end up installing that firmware.

Well the Hardware is the same on both devices - We can Flash T-Mobile Custom Roms on the SM-N910W8 without any problems - I know that it's almost impossible to find a motherboard that says it is specifically for the Canadian Note 4 - If you can get the motherboard for the SM-N910T at a decent price and IF you can find out if it's new (or some kind of guarantee that it's not dead) I'd go for it ?

[Galaxy Note 4 General] shaggyskunk:
Yeah the only concern is are you throwing away $57.94... Unless you can get some kind of assurance / guarantee that the motherboard isn't suffering from the same issue as the one you currently have in your Note 4...... That's the trouble with buying used electronic components ?

Has anyone tried kyubi on our canadian device? Was anyone able to achieve a 7hr sot that some people in that thread have mentioned.

Another question is how would I go about downgrading to lollipop from marshmallow. I'm currently on a note 7 rom (magma v1). I tried directly going into download mode and odin on 5.1.1, but right when I click start, it gives me a fail. Do i need to first odin back to stock mm, then proceed to odin to stock lollipop?
[Galaxy Note 4 General] Wadadli:

Not an expert by any means, but I have a strong feeling you need to do what you just wrote ie an initial back to stock through Odin. Remember seeing this question in the past, so a search might yield the answer.
[Galaxy Note 4 General] VlitalityX:
I highly suggest everyone with the w8 to upgrade their firmware to the Puerto Rican version (latest). I flashed it yesterday, then flashed a custom rom (Magma v2.01), then flashed Flashpoint kernel v3.1, I'm getting great battery life as well as able to pass safetynet. When I was on the canadian dpk1 firmware, using flashpoint or ramkernel, my battery usage would drop very intensly, average SOT was 1.5 hrs. With the new bootloader, the SOT with flashpoint it's gotten comparable to BeastMode's SOT and maybe even better. With a huge plus, I'm now able to use google pay, and play pokemon go :P

The Puerto Rican stock is riddled with crapware, but with a custom rom, it's a godsend.

First just need to say, RIP to your note :( ...At this point its the slow failure of the eMMC chip (Your 32GB internal storage). You can check out the lawsuit thread going, since some people have managed to get it raised with the BBB and force Samsung to repair. Otherwise a new motherboard is the only fix.

I went through 2 Note 4's because of this in a short period of time. Only short term fix was to install a Wakelock app and force it to not put the device to sleep. This kept it running, but if the phone dies because of a dead battery, I had a 20% chance of it powering back on. If it didn't. I would need to remove my case and battery, put the device in my fridge for 20 minutes or so in a ziplock bag and then it would power up after being cold.
[Galaxy Note 4 General] emilgue:
My original Note 4 also died from the same cause and the seller refused to cover it. I did installed some non stock rom and rooted it, so I don't have a strong footing to demand warranty coverage.
[Galaxy Note 4 General] kojam:
Pine Sol, there is a fix to recover it. Search up xda. You ćcan probably find a link on Google.

Mine died long ago. Good thing I was a part of this xda community else I would probably have thrown it out. Having faith in this community I knew a fix would could someday. Checked for 6 months and this amazing community spit out a fix. PHONE RECOVERED!!!

But cash387 is right. You will have to use a wakelock app ...AND...if it does turn off, then u will have to put it in the fridge/freezer for about 10 min to get to power back on (I’m talking about AFTER u have found done the xda recovery/fix)

Lawsuit?! Gotta find that link!!! I successfully got Samsung to replace my Note 3 way beyond the warranty, even though it was quite evident that it rooted and did things to void the warranty. I provided them with tons of evidence that the phone had known issues and Samsung replaced thousands of phones in the US customers. I wrote my complaint to the Samsung Canada CEO.

I haven’t been able to get a reply regarding the 4! A bunch of us at work have the 4 and ALL OF THEM suffered the infamous Mac failure!

I want in on the lawsuit!

Would appreciate the link please.

Pine Sol, just realized that you had a link to follow ..LOL. Sorry for not reading properly. Actually, I believe I also used that link (including the one I just provided to fix my phone.

As well, I just remembered what even brought me to xda today (I used to spend waaaaaay TOO MUCH. time on this site! I’ve had to try to avoid it like a recovering alcoholic trying to avoid alcohol. LOL).

Anyone know of a GOOD RELIABLE eBay source where I can buy an unlocked clean N910T (T-Mobile) logic board for my N910W8? I just found sellers on aliexpress but don’t know how reliable they are. Not many reviews for any of the sellers. Plus, delivery takes FOREVER when I order from China!

I think I can follow youtube vids to change the board. My coworker paid some little shop here in the city to do it. He was charged over $140. I really hope they didn’t use another n910w8 board, since it will end up failing again.

I didn't get the mmc read failure as some have had. However my Note 4 just died on me last week.

From heavy use I had simply worn out the flash storage from too many writes and it was done for lol.

I think the Note 4's are reaching that point where more and more people that still use them will be running into aging issues.

To keep me going and get all data running again I bought a used one off eBay and restored my nandroid back up.

I've held off upgrading due to cost and frustration of new phones getting more and more expensive, and yet never feeling like their hardware and design actually justify the price tag.

Currently though I'm looking towards getting that new ASUS ROG phone once it goes on sale here, and if its priced under $1,000 CAD (hoping for no higher then $899 CAD for the 8GB/128GB storage base model) it automatically makes its better then Samsung or Apple IMO.

If the price is too high on launch or the reviews show it having too many negatives or something, then I'm starting to be interested in the One Plus 6.
