Hi there. I was just wondering if anyone else has experienced this issue.
I used to think it was only caused when I changed my phone to a custom Kernel but its also happening on the stock rom and kernel too and even a reset and wipe didn't fix it.
Basically after a while of usage the phone just gets extremely slow and laggy and it seems to be related to GPU not CPU as when I run Quadrant my CPU scores are the same when this issue happenes but in graphic tests the fps has gone from 60fps to 30fps.
The only way to fix this is turning the screen off and then back on again. Once I do that it goes back to normal.
Its not a heat issue or DVFS issue as I turned DVFS off and and it still happenes and my temps are the same as usual. it just seems to happen randomly after iv been using it for a while.
Has anyone else experienced this and does this seem to be a fault?
Scrolling through the home screens becomes really laggy when it happenes like the speed has halved so its easy to spot.
I haven't noticed anything in stock.
Maybe trying a firmware 4epair through Kies. Not Odin.
And then try again in stock and if all is well try in custom
Hi Guys,
I am a new Note 4 user, I've had note 2 before. Recently I have used Z3, OneplusOne and S5, which in my opinion other than the S5, the phones were smooth and laggieness was non existence. I have since changed to the Note 4 and immediately I have realised that even in the kitkat (currently running lollipop) that the phone lags when changing between the programs, turning on the camera, or even after a picture has been taken it takes a while to get to respond. Hardwar-wise I believe the Note 4 is very respective and I can only blame this on the software. I have since upgraded to lollipop and I must say the performance is no different than before. Could anyone tell me without rooting and installing a modified rom, is there a way to increase the smoothness of the phone? it is because of the bloatware? how to de-bloat? or is it just how it is?
Thanks
Patrick
the better is a clean installation and after that come back and report any issue's
Thanks vagenrider but this issue was already apparent when I first used the phone right out of the box and noticed the lag.

hi,
I can say this,
that i had my Note4 (N910F rooted, stock Rom.) since October 2014 till now.
Overall i had little or no "lag" of note. (apart from Recent button plus an setting issue.. minor )
Over this period of time, if i found/noticed a bit of "lag" and i found culprit, causing the problem, I would uninstall app,
i also noticed, so far that it has always been a 3rd party (badly coded.. or on lollipop the app was not "playing" nicely.. etc etc)
So overall.... when i was on Android v 4.4.4 or now on Lollipop my device has been working fine.. battery use, been good, very, very smooth
So all i can say, if you have issues it is either you have a faulty device or an app/combination of apps causing lag.or setting issue
I have stated this, in many of my post that i have following devices.. on hand
Note 4, Note 3,Note 8.0 (tab) Note 2 and they all running fine..( 100% satisfaction)
Bottom line
is that i think i am in a good position to state that my Note 4 compares 100%plus, with my Note3(which is a very very, good device, smooth no lag, etc etc)
Above is just my opinion and i hope that you can sort out your device
Good luck

I am having the same issues with my device. I've had it with both lollipop and KK. I've had multiple ROMS (all stock). I've done fresh installs, cleaned cache, disabled apps, and completely run with none of my apps installed. All the same issues, as you've mentioned. I'm thinking of returning my note 4 if they don't fix it by 5.1.1 or August. This device cost way too much for these kinds of issues... :-\

About debloating:
Without root you cannot really debloat the rom. You can only try to holding every app you don't need and drag&drop on touch wiz launcher and drag&drop it to "app details". New window with details will be prompted and you can delete or deactivate the app. This is everything you can do on stock to debloat.
About the main problem:
Also here without root and custom rom I could only suggest to try following:
Go to Settings app.
Scroll down to device information.
Tap few times (I think 5 times shoul it be) on build number to activate developer options.
Go back to main screen of settings, scroll down to developer options and open them.
So from here you can try to change following values:
- Force GPU rendering
- Turn off hardware overlays
- lower values for animations (all three) or just set them to zero if you don't need them. That gives really bounce speed (but mainly just for eyes, it doesn't really chages overall performance of device, just little bit maybe)
The nagtive thing of GPU and harware overlay is little bit higher the battery drain then usual.

Thanks for that!! I've just done the above, will use this setting for a while and see how it goes.
Hi Guys, after applying vbaschen's suggestion I believe the phone has improved in terms of window changing and smoothness in operation. Battery discharge hasn't affected me that much given the battery has always lasted an entire day of heavy use and I plug it in everynight. I would recommend this quick mod. Thanks again vbaschen.

Right on. I was going to recommend reducing the animation values as well as that is usually the case. Hope it helped!

I went for a completely different solution: the Note 4's Snapdragon cpu has the bad habit of heating up very quickly. Two or three minutes of heavy usage (gaming/emulation, or worst: piles of file operations, e.g. media scanner) make it shoot up to 85° C. To prevent serious damage, the cpu is then automatically scaled down to extremely low values, which results in abysmal performance. When I first unboxed my N910F and inserted my old sdcard, the media scanner went haywire because my sdcard was faulty (works alright in my old Note 2, but the Note 4 is picky). The phone quickly got too hot to even touch, ran sluggish as hell (AnTuTu scores between 24000 and 29000), then shut itself down. :crying:
After I had replaced the sdcard, things got better, but only when I didn't put too much load on the phone: 52000 AnTuTu points in the morning (first thing to do with the cold phone), but getting worse steadily until I couldn't score more than 43000 points.
Now, after a lot of fiddling and tweaking (Kitkat, Lollipop, Stock, Custom, CM 12.1), I finally settled for (Lollipop) Emotion Revolution R8 ROM along with the Emotion nightly kernel (r17) and (most important) Synapse kernel tweaker. Instead of overclocking the blasted thing even more, I actually downclocked it one step (2572,8 MHz). The result: a rock stable phone that actually runs way better than with the higher (stock) clock rate. The cpu hardly ever scratches 70° C, and usually stays around 65° C even when I run demanding apps like PPSSPP, Dosbox, or Real Racing 3 (don't like that one, but it beats the s**t out of the cpu - 85° with stock cpu clock!). AnTuTu scores reach about 51500 - almost as much as with stock clock rate - but several times in a row now, with no performance hit. So, even though the peak performance may be one or two percent lower, I can run my phone for hours without any performance drops. Oh, and it's good for battery life, of course. :good:
So, if you're rooted, you may want to give it a shot. :fingers-crossed:
Hi.
So, I bought a Galaxy A5 2016 as my new daily driver. What a beautiful phone, really. Pretty fast, better than I expected, I must say. But things are not going so well.
I have a intense usage pattern. On the morning, I use Spotify (sth like 20-30 min), then e-mail sync through the day (every 5m) + browsing and messaging apps. Then, more 40m of Spotify. Everything seems in pair with other devices with similar price and hardware specs. Until today.
As my usage pattern reports, I always use Spotify for 20-30 mins every morning. Today, I was using it, and the song suddenly stopped. As a coincidence, my 3G connection is limited - so it's not operating on its normal speed, which roams about 3Mbps~5Mbps - so I thought that the connection was dropped. When I pressed the HOME button, nothing happened. The song suddenly stopped, along with the system. 10 seconds later, the song returned to play. Less than 5 minutes later, the same bug happened again - same MO. 10 seconds off, returns, didn't happen again. Tested Spotify on the afternoon (same conditions + SAMSUNG personal music player running together), didn't happen too.
Along with that, my RAM usage is pretty high. Besides my downloaded applications, the RAM is mostly consumed by the system itself - so maybe root will fix it. But I'd like to know if anyone ran into this abnormal RAM usage. I even thought about memory leak, but that seems a bit odd, since the memory leak stopped being reported in Android 5.1.
Has anyone ran into any of this issues before? Thanks in advance.
I have it for two days now, yup, ram is at least 80% when I clean up the memory.
It's also pretty hot during the lightest use, average temperature is 35C. When idle it's at least 28C. Anyway, glass backpanel feels really hot, is it normal?
What's your average temperature?
I also want to report that i have the same problem on my A510F on MM 6.0.1 (no root). I have disabled many apps like Skype, S-voice, all the microsoft apps and some system apps that could be disabled but pretty much nothing changed... My ram usage is always around 70%, if i clean it it goes down to 55%-60% but then it gets full again. This does have an impact on the overall performance since on heavy games and generally heavy usage, the phone lags and gets hot. I want to know if ROOTING the device and installing xposed modules and/or uninstalling much of the samsung crap will help the phone breath normally. Any answer or tip is welcome
I have at least 70% of RAM usage and i think it is ok... but there ia a problem over 85-90%: then I have almost same problem as you. It's my second A5 16 and still have this problem. I don't know what to do. This issue happens increasingly. I have 5.1.1 and still hope for removing this problem with marshmallow update.
Anyone more has this problem?
Any ideas what to do?
It makes this phone useless when happens so often![emoji35]

Same problems on MM too, 70-85% RAM usage...hope to solve in feature updates.
Sent from my SM-T560 using XDA-Developers mobile app
I don't see anything bad in usage above 85%, the problem is closing, crashing and lagging apps.
If MM (update for Europe/Poland) doesn't fix it I will probably sell this phone. It's unbelievable to crash apps during using just a 2 of them (in my case Spotify and instagram at top and a few used before).

Did anyone try to fix this problem by "turning off apps in background" in programist options?
I would really like to do that, but every time when I turn this option ON and go back to settings and again go to programist settings it is turned off again - can anyone try to do it on yours phone?
Skrobnięte z A5 '16
Mine is always around 55~60% but free RAM = wasted RAM in Android
More free RAM =/= Smoothness
My A5 2016 can multitask very well (Even with games!) and not much lags
So why some of A5's has so huge problems with ram managing?
Skrobnięte z A5 '16
Is there any stock Android like ROM available for Galaxy a5?
I get MM update yesterday, after 24 I can say my problem stops. Phone seem to be faster and don't get above 87% ram usage.
I didn't restore A5 16 to factory settings.

I have problem with level battery when Reach 5% my mobile trun off ??? Plz slov
@up
First thing which you should do is restoring to factory settings and then we will see.

did this happen after u do an update?
im using A5 (2016) for my daily driver.. using spotify a lot too when comutting. never failed me until now (4 month). in my region A5 still dont get MM yet. so i manually upgrade to ROM everymonth with russia region (MM). suprisingly samsung do apply 'android security update' every month for A series.
is ur device is locked by some carrier? AT-T /other? if not try flashing with Russia ROM. u can flash with odin. fear not, ur data & apps still intact. if u flash official fw with odin.
for ram usage, i think this is not a problem. the multitasking still flawless for 2GB of ram. the feature i like from this phone is the GPS. lock very fast. im glad buying this phone. the only downside for me is 'no notification led'
So, as the title says, there may be a way to prevent your device from freezing due to unlocked bootloader. Here are 2 things I've discovered:
1) Most of you may already know of this: If you switch off cores 3 and 4 of your CPU in the app Kernel Adiutor you can prevent the freezing issue. However, you lose half your CPU power, and if you leave it that way for long you can't switch those cores back on for some reason, and you'll have to reboot your device(else your battery will drain out if left as is, from my experience), so it's quite a cumbersome task.
2) If you play games that require little more than average ram and CPU power(even games like hill climb) your phone won't freeze while playing. I play this game called Vainglory, and after having played for over 10 hours, I can say for sure it didn't freeze even once.
From these two things I can draw up a vague conclusion that the phone freezes when the CPU isn't doing anything much. When we switch off 2 cores, the workload increases on the CPU, this making it busy(which also leads to quick drain). Same goes for gaming.
So how do we work on that? I'm not sure. Anyone have any ideas? Maybe someone can create a kernel compatible with RR and other cm13 roms which has what's needed. Or maybe try a different CPU governor? Well, just wanted to put it out there.
I tried all what you're trying to do and I understand that. The thing is that it will freeze no matter what.
Of course you can try but don't expect too much.
Goodluck!
I am facing this same issue suddenly
there is no connection between ifwi and cpu core

Who said there is?
Another thing I found:
When you use kernel adiutor to switch off cores 3 and 4, and use your phone normally, the instant when your phone would have frozen if it weren't for the app, is when your phone gets much slower suddenly. At this point, you'll no longer be able to switch those cores back on, and only a reboot will resolve that.
I've mentioned this so-called "method" of preventing Z5 freeze long ago. I can confirm that switching off cores 3 and 4 somehow halts the phone's urge to freeze. I could've lived with limiting my "power use" as I'm not really a fan of entrusting your phone with large tasks. However, what turned me off was that disabling either one of cores 3 and 4 also disables the camera somehow (Ring a bell, Z5 users who lose their cameras whenever their bootloaders are unlocked?)
No one really replied with certainty back then and up to now, that thread is still collecting cobwebs.
Question: is battery drain a characteristic of disabling cores? I disabled only core 4. Cores 1, 2, and 3 are up and my ROM (Lineage 14.1) runs perfectly without freezing.
So I don't know when this started happening but almost every single game on my Galaxy S7 lags after about a minute of playing, like the frame rate will get cut down from 60fps to a choppy 30-50fps, and stay that way unless I exit to the home screen and back into the game or press the app switcher button for a second and go back into the game, then it jumps back to 60fps for a little bit and the lag goes away but it always comes back.
I have no idea what's causing this problem and I'm tempted to factory reset my phone to see if that fixes it because I've tried almost everything (disable game launcher and tools, disable the packages, game mode, high performance mode, delete cache, rebooting, etc.)
Does anyone else have this problem and could it be a certain app using resources in the background that's causing lag? I'm on the stock rom from at&t, no root and no bootloader unlocked, everything is pretty much vanilla.
Finally after months of trying to figure this out, I fixed it by pure luck.
Every Galaxy S7 user should do the following:
1. Download Game Tuner
2. Create a custom profile
3. Set FPS to 60
NOW ON TO THE MOST IMPORTANT STEP!
4. Set HW Performance to +4
HW Performance affects the stupid throttling that games seem to do that prevents smooth 60fps in an effort to preserve battery life and keep heat down I'm guessing. Setting it to +4 fixed all the lag I was getting in every single game.
