Is there currently any ROM and/or Custom kernel, that doesn't suffer from the memory leak bug?
I am aware that similar questions come up on every other thread.
I also would love to try for myself. Stock KitKat and stock lollipop both suffer from the bug. On lollipop I have much more free ram, but chrome and other apps still redraw when multitasking.
Problem is, I don't want to unlock my bootloader yet, as I'm still considering giving back the phone.
Thanks in advance for any insightful advice.

You seriously want an answer to that?
Just read "every other thread", then come to a conclusion and act accordingly. Or don't, since you don't want to unlock. Your choice.

I've been reading "every other thread".
And yes, I seriously want an answer to that.
I never said, that I didn't want to unlock my bootloader, eventually I do want to unlock it. But according to your reply, I suppose you don't understand that. Nevermind.
Thanks, anyway.
Titan Prime will yield you the best results with memory, from my experience.
Besides that, all you can do is sit and wait for 5.1. And hope that it will fix the problem.
I've got a (german) XT1068, and I was on build RETDEALL 21.85-14 for the longest time (KK 4.4.4). The phone was sometimes close to unusable due to the memory issues: Almost every time I went back to my launcher (Nova) the widgets would reload (all two of them), every 5th time the whole launcher would have to be restarted. When listening to music, the player would often be killed when it's not the foreground app. This all was already with tuned settings and the like. Simply put, my Galaxy S2 was a much better phone, with better performance and multitasking (same amount of ram, but dual core only)...
I've updated to the 5.0.2 build that was (finally) released a few days ago (22.46-28). It's a world of difference. I would say the problems are either gone or at least they got the biggest of issues under control. So far I haven't had it running without a reboot for multiple days (installing xposed and associated modules tends to require reboots), but so far everything is looking perfectly fine. Widgets haven't reloaded even once, let alone the launcher. Multitasking works, even larger apps weren't killed (like reddit news, which tends to use quite a bit of ram after scrolling for a bit).
So I don't know whether it's fixed, but at the very least this is a fully-stock-option that works perfectly fine (for me), even though I'm rooted and use XPosed that is by no means necessary.
I also have the German OTA update. Everything works fine. As for the memory leak for me that is a thing of the past, was really bad in 4.4.4 and I had the same version as the above poster. Everything stopped in the background, in point of fact there was no multitasking. With 5.0.2 I can play music run a navigation app, surf the net no problem and still see over 400Mbyte free ram in setting all without the dreaded app has stopped working or seeing apps restarting.

4.4.4 didn't have a memory leak, just high minfree values I think.
Lollipop does have a memory leak (and thats mostly googles fault) and the memory management is very buggy when compared to kitkat. The memory leak doesn't show instantly, it shows after some time and you can just reboot the phone to "solve the problem".
If you want a really good rom for multitasking I recommend CM 11 or some rom based on it.
4.4.4 definitely has some serious issues on the MotoG, it was not just the min free values. I had tuned those (basically tried everything), but it made no real difference. So far, LP feels like it's a different phone.
I agree. I can't understand how people would go back to KitKat after trying lollipop. Chrome and other apps still redraw when multitasking though. :\
Let's see if 5.1 fixes that.
BTW: does anyone get graphic glitches in Tapatalk and chrome? Sometimes whole areas of the screen turn glitchy, until I switch to another app or press the back key. (Glitchy= pixels in all colours, like an overheated GPU on a PC would produce.)
Hello people i just received the OTA notification, but i'm worried to update, to be honest my phone worked pretty well till today and i'm very satisfied with it, but it's kinda annoying the notification popup , i tried to stop the service as well but it keeps popping out.
Anyways i bought this phone cause it's such a great phone for the price, and cause i knew it was going to get Lollipop update, and now that there is the update i'm kinda conflicted about so many differents comments around the forums, i checked here, some other forums, and on reddit but i couldn't find a proper review of the Pro/Cons to updating the phone to Lollipop 5.0.2 (most of the review i found were of the previous version of L, and i read that 5.0.2 got some major fixes ); so there's anyone that can kindly explain me if it regrets updating the phone, or what are the issues? battery life improvement? i know that it gets a better multitasking, but some people complain that is "sluggish"? also there's anyway to change or remove the white background from the app drawer?
thanks in advance for the help.
I updated my phone more than a month ago. At first the phone seemed sluggish ,as you said, and even after a full wipe things didn't get better. The thing is that after a few days the phone's performance was just as smooth as kitkat for me ( I guess the rom settled ) . Battery life is the same , although lollipop may seem to need more resources at times , and I also installed nova launcher with moonshine icon theme to get rid of the white app drawer background. In a nutshell , the only difference for me is the visuals / new features like ambient display which I happily use. I don't play games on my phone but I listen to music , watch videos on youtube and stay online for a few hours per day switching between apps. The only problem for me is the blurry camera ( which is also an issue on kitkat ) and the lack of actual silent mode.
ps. I would strongly recommend a full wipe before and after installing and disabling apps you dont need from settings in order to save battery and resources. Don't forget to back up everything before wiping / updating
It is worth it. The features and the UI are definitely great, but don't expect any real RAM improvements. Performance-wise, the phone still multitasks like my old Galaxy Y (which had 256mb of RAM), and I only keep WhatsApp on the background.
But hey, it's not any worse than KitKat and it's pretty, so I recommend it.
Agreed.
Material design looks good, performance is the same and so it's battery life (at least in my experience). I am happy with it.
I got the update 4 days ago and haven't had any problems. Is it faster? Hard to tell but it certainly isn't any slower.
Ram management for me is much better, no problems with multitasking, navigating listening to music, surfing the net, still shows 464Mbyte ram free and no restarts. No lag at all on any apps (59) all of which work fine.
Battery performance is in line with what I had on KitKat, which was pretty good, (Don't forget where you put your recharge cable). I have to admit that I am not a power user, (I can get up to 3 days out of one charge) but I use it a lot to record tracks with OruxMaps when I am walking, GPS on and screen off.
I don't use mobile data so have it turned off on all apps that use it, I have a separate mobile router (Much lower cost).
Finally from my experience I would say that updating was worth it, just to get rid of the terrible multitasking that came with KitKat 4.4.4.
XT1068 dual sim Android 5.0.2 System version 22.26.1. rtde.retdall.en.DE.retde
Hello.
I've downgraded from 5.1 to 4.4.4 a while back, and I'm quite happy with the phone.
But, sadly, the old bugs from 4.4.4 came back as well.
The one that I'd like to solve, is the battery drain by Android OS.
I've noticed that after updating some apps, it's likely to happen. The only way to solve it, is by clearing the phone's cache (this includes a restart, of course)
It will work ok for some days, and then it would just re appear with no apparent reason.
I don't remember having this issue when I was natively at 4.4.4... That means this was not an issue at the time, or I did something to disarm the issue.
If the second one is the scenario, I don't recall what I did...
Now, I've most of Google Services disabled (no google now, or hello moto)... Only thin I use, is location at battery saving setting.
What else would I need to check?.
Phone does have a good deep sleep time.
Thanks in advance!
After a lot of issues i just ended up downgrading back to kitkat on my galaxyTab S8.4 wifi, from lollipop.
Issues i was experiencing were:
-totally unreliable battery meter & performance. - Could read 100%, and 10 mins later would read 5% and turn off.
-screen flicker - lines would flicker across the screen randomly, usually before the device crashed.
-Rebooting - the device would randomly reboot, but usually happened 3-4 times per hour, making the device useless.
-screen freeze - the touchscreen would stop working randomly, usually before it rebooted itself.
Ive just gone back to kitkat (voided my warranty in the process) and its still to be seen if downgrading resolves the battery issue, but already the screen flicker seems to be gone. Il update after a day or two use.
Very annoyed with Samsung for releasing an unusable update that rendered the tablet useless & the solution was to load a rom myself, voiding the warranty.
Have experienced absolutely none of the issues you refer to on my SM-T805.
Runs just fine for me.
Downgrading to KITKAT doesn't void your warranty.

I agree with ashyx , my tab s runs fine n dandy , sounds like you have a faulty unit schmintan
I don't know if your tablet has Knox, you can see status if you go under status in about device, usually, and see if it is "official" or not.
Far as what you did, before you went and loaded a ROM, I would have done a factory reset. Quite often, settings/apps brought over from a previous version cause issue. I don't care if the upgrade tells you too or not, read through the forums and you'll see it littered with people stating how they noticed a massive improvement after their upgrade once they factory reset. Yes, it does suck, but these days Android makes it very easy to do.

Hi, have you solved The issue downvrading? I have The same problems you described.
same issues
White lines then crashes, battery life under 4 hours,
Sounds like a case of broken hardware or one seriously misbehaving application. And in general, if nothing works, I'd recommend to do a full factory reset of the tablet after the lollipop upgrade (erasing all of your data and settings of course). The only issue that concerns me about lollipop is the increase in battery drain at idle. You need to hunt down for the apps that keep your tablet awake. But spend a full battery charge in minutes? No way. Impossible. Get the tablet replaced.
I've been having the same issues. When I did a clean install, the tablet worked fine. However, as I install various apps, the issue begins again. I haven't been able to identify a particular app.
Going to try Marshmallow and see if it's more stable
If you both post your apps list that might be interesting see if you both share an app?

nope. no stable mm roms yet.
Well, I've upgraded to Marshmallow and whilst it took a few goes to get it up and running properly (problems with installing gapps) it's working fine (mostly) now.
I've only had it running for a day but it is much smoother and quicker than kitkat and lollipop. So far there hasn't been any random shutdowns. It's too early to say whether battery life is better.
The only problems I've had is the camera isn't working (haven't bothered to look for a fix yet) and auto rotation doesn't work all the time.
I'll keep you up to date on how things go but so far I'm very pleased with the upgrade. I might now upgrade my 10.5

Hola, which procedure did you follow to downgrade OS to kitkat? I m right now on official Lollipop without root.
I had a notion that even if we downgrade to kitkat screen flicker will remain.
Awaiting your reply- thanks in advance

If your issues are caused by Lollipop wouldn't everyone one else with Lollipop experience the same issues? I have absolutely none of the problems you mentioned and I have had Lollipop installed since it was first made available for this tab. Seems to me you more then likely have a hardware problem. You said you were going to update in a day or two but you haven't so far. I'm curious if downgrading solved your issues.

SM-T705Y running 5.0.2 (LRX22G)
looks like update from 20th May which would be around when this started
I have a N6 purchased Dec 2015 new from Amazon. The only mods, if you can call it that is, I have unlocked the boot loader. I am currently running N6F26Y sideloaded via ADB.
The phone was great when I first got it but now after about a day or so of usage it becomes slow and sluggish and unresponsive I have to restart it to use it. I have done a factory reset a couple of times which gets it back to normal for a week or so and then the problem recurs. Occasionally I will delete the cache which also helps. Snapchat is one of the worse apps - crashes the phone regularly and is a very slow app.
Also the camera can get very slow often taking seconds to take one photo.
I love the phone but it's becoming unusable now. The contrast between this and a new phone (I have purchased a Moto Z) is like night and day. The Moto Z runs instantly, has no lag and is a nice phone. But what I like about the N6 is the large screen which makes it great for videos etc.
Short of perhaps flashing some custom ROM is there anything I could be doing?
I'd recommend flashing a rom like pure nexus, super stable that should fix your problem, otherwise you've done all you can and is the easiest fix

Hello,
It seems like some apps are really slowing down your phone. I use my N6 at home for web browsing mostly as I have a Pixel XL now. Just like you I love the screen size.
The camera has always been slow fore, because of the time it takes to focus...
Did you try using your phone a few days without Snapchat installed? Maybe you also have other misbehaving​ apps installed.
Uninstall Snapchat and other apps and start from here. Reinstall one per one with a few days interval. See if the issue still occurs.
Installing a custom ROM + kernel will likely speed up things a little bit. I second @Dugaldrob with Pure Nexus and I'd suggest ElementalX kernel on top. Running this combo on N6, N6P and Pixel XL and they work flawlessly.
I don't believe installing a custom ROM alone will fix your issue though. Stock ROM shouldn't cause the phone to slow down to the point you need to reboot to use it.
Finding the culprit will...
Good luck...

First step is to remove Snapchat. I rarely use the app and only because my daughter sends stuff on it. I am going to tell her to send me stuff via another method
If that doesn't work then it's a new ROM. I have performed ROM installs before but have never flashed a new kernel on a phone before so that will be a new experience. Hopefully I won't brick the phone

I've been running Pure Nexus and wanted to let peeps know I put Nitrogen on and man it's so smooth, my wifi tether is back and I went to sleep last night with 50% battery still. When I installed it I opted for the nano gapps I think so like 175mb for minimal apps and maybe that's why it's running so efficient. Maybe I could have re-installed Pure Nexus with a clean install and it would have gotten better but it was a good time to try something else. Also when Nitrogen got an update I was notified just like stock and it downloaded. I didn't even know these could do that. Anyways give it a try and you might just switch back. I was looking into new phones but if it keeps working so smooth with battery longer than a day then I'm fine for now.
Snap chat is not that big of an issue. What I have found to cause the device to slow down is normally almost full device storage and a crappy cache release code in apps. Some apps don't release their cache properly. So it causes lag. This is why a reboot seems to fix it.
While a custom rom may fix this issue it is not the solution. The proper solution is to find what is causing it and fix/repair/ditch it.
Worst offenders for crappy code in my thoughts. Other will disagree with one on this list I am sure. So don't bother. I know people swear by it. It runs like crap for me at times and causes my whole device to lag until I close it out.

3 Google Chrome ( don't do it lol)

Mind you this is just a list on my usage. It may very per user and even device (considering different hardware)

I can confirm this, because I've removed these apps (-whatsapp) and also decrypted the data partition...
My N6 is fast.
Maybe a lite stock ROM and an other kernel is a good start.

Currently I have FB, FB messenger, and Chrome but when I installed gapps I chose a super lite install so tons of bloat and google apps were not installed and my battery has gone way up and it's so smooth. I'm sure even when we don't use apps they're always doing something in the background. I bet you're right and a stock lite ROM would be good too with the minimal bs apps.

Thanks for the advice. Of the list of apps above I have only Chrome and Hangouts. I really can't see replacing either of them.
I also should have pointed out that the phone locks up randomly requiring a hard reset. I wonder if an errant app could cause that or I have some RAM problem. Certainly on a PC bad RAM can use in Windows a blue screen or something but perhaps Android isn't so forgiving?

I would flash TWRP, flash supersu in TWRP to root, make a complete backup in twrp, then remove whatever Google apps you're not using with a system app removal app. Getting some of that bloat off the device should help. If it's still laggy, then look into a custom ROM. I run Tesla on my Nexus 6 with none of the issues you're having. I don't decrypt it either
Running abdroid 7.1 here. I dont get any slowdowns, at leas until the battery doesnt drop below 50 and 25 percent.
Im running a custom kernel and my phone is rooted. Everything else is stock.
Can you flash a custom kernel and presumably TWRP without wiping the phone? If so then might try that before a custom ROM

Hello,
Since your bootloader is unlocked, flash TWRP and install the kernel, no problem.
Might give you a slight boost at first sight, but your device will likely slow down over time anyway...
Cheers...
I'm on 7.0 with the April SP. I have dozens of apps installed, including Hangouts. I use Firefox for browsing, I like it better than chrome (and you can install an ad blocker).
My camera slows down when the battery is under 40%, and the whole device slows dramatically, though not unusable, at or below 5%. But otherwise, no issues what so ever.
One solution that I have not seen suggested here is resetting the device and NOT taking the Google account backup of all your apps. I would suggest making a completely clean install of the factory rom you have and installing one or two apps at a time, most important to you first. And do this for a few days/weeks until you find the app that's misbehaving.
Although there are general bad players out there, this bad app could be unique to your device. Just because all devices of the same model have the same specs and components, doesn't mean that there isn't variability in parts quality.
I would do this before trying any new roms or kernels. Find the true problem first.
Good luck!
edit:
I had another idea: Go into your battery stats and network stats and storage stats and see if any app seems to be using too much of any, or all of the 3. This may get you the answer more quickly.
