Hi everyone,
My Tmobile Note 4 lags and freezes quite a bit. I've done many things to include a hard reset, but the lag is back. It can get bad sometimes. So I decided to install Trepn Profiler and the CPU usage for the Samsung Keyboard app varies from 10-30% when the keyboard isn't being used. I tried Greenify, but it won't force close the Samsung Keyboard app. Why is this program using the CPU this much when it's not being used? By the way, the Samsung Keyboard app is always at the top of the list on CPU usage.
In either case, what are your thoughts and how to fix this? What's the best way of tracking down apps that cause this beast to slow down and lag? I have too many apps loaded to uninstall them and track down the culprit or culprits one by one.
Thanks,
GP

Hi,
i've started to noticed that my Tab P1000 is lagging quite badly. Open and closing of any apps takes about 1 second or so. i'm not sure what's wrong and don't know when it started. i then explore into memory usage and memory booster app is telling me that free memory is only about 34%. The number of tasks running in the background is also quite huge (24 at a time).
Is the memory usage normal? i've tried to delete any un-used apps but it doesn't seem to help. Are there any ways i can improve the memory and the overall performance?
i'm running custom rom (overcome) kernal 2.6.35.7 overcome v3.3.1.
Any advice will be appreciated.
I had this, I cleared all of the app cache files and seems a lot better now.

you can try to wipe app cache, then use autoruns to disable all rubbish. and use overclock
I use taskxp from market, not just because its a task killer, but because it allows you to switch easily between open tasks, very helpful if you are running more tasks than holding home key menu will show (which is only 8 last accessed tasks)... anyway as a task killer it is very stable and customizable, I never have a lag or a unwanted task running in background (most games I notice will run in background even when you don't open them and I just kill them and free up my memory

This Taskxp thingy seems very handy! Thanks

I got my Xperia Z1 about a month ago, and I've noticed some issues with RAM management (or possibly under-optimized third-party apps). Although I haven't had much luck in replicating the problem, I noticed it happen a few times after a Firefox internet session, or after playing a graphically intensive game like Dead Trigger 2. The app would either close by itself (not crash, as in, there were no error messages), or, after I'd close it, I'd notice my launcher (Nova Launcher Prime) go into a restart loop. A quick glance at the running apps section in settings shows 50-100 MB of free ram, and all "constantly running" apps (launcher, viber, zooper widget, k9-mail, swiftkey, tasker, etc.) stuck, for want of a better phrase, in a restarting loop (due to lack of ram I guess).
I tried running Fast Reboot (a task killer) to see if I could regain stability of the system, but it kills only a few system tasks, freeing up to a measly 50 MB of RAM, which makes me wonder (in aggravation) just where the RAM is being used. The only way the running apps would stop closing and restarting (and I need the launcher stable) is to reboot. I'm not sure if the system would stabilize after x minutes, as I only waited for a minute or two before rebooting so that I could open another app/game.
I'm not trying to start yet another debate on necessity of used RAM on Android and efficiency/futility of task managers/killers, but what I described above really seems like poor RAM management to me. I've had a few android devices in the past, and experienced various problems /errors, but never something like this.
Has anybody had a similar issue, or have any tips?
My Xperia Z1 C6903 is currently running on rooted stock 14.2.A.0.290
Although i dont get force closes, but ive noticed most of the ram is taken by the phone itself, right now for me it says i have 1.1gb in use, when i close everything i have just a slight (barely even noticeable) increase in free ram, when i click on cached processes and close all one by one ive seen it increases the ram use instead of decreasing it?
But, do you use apps like setcpu? You can keep it on performance and keep the min slider to the lowest and the max slider to max, it runs stable and gives you performance when you need it, and no performance when you dont need it.
If all fails, try deleting system apps that you barely even use or need... Becareful what you delete tho!

Thanks for the reply. No, I've used apps like that in the past, but haven't installed anything similar on the Z1, because I noticed in BetterBatteryStats that the CPU speed goes down often when the screen is off, and up when, I suppose, it's required, such as in intensive games...
What apps do you use? For example facebook, YouTube, browser etc
Ive checked again on my cached apps and to my surprise, AOSP browser takes up 208mb!
Facebook takes up 48mb, and youtube takes up 22mb.
It just depends on the apps you have installed, some use the ram even while the phone is asleep.
Ive stopped those and a huge difference was made on freeing up my ram!
What i dont get is tho why sony advertises 2.2ghz quadcore if the phone itself takes most of it?
Just delete the apps you dont need from "all apps".
Hello Everyone,
With all my previous Samsung Galaxy devices, I have experienced this lag or delay in Previewing the photo after taking the photo from Samsung camera app. I have used Note 1, Note 2, S4, they all had this lag/delay after sometime of use.
Now I am experiencing the same lag/delay with my Note 4! Its international N910F Snagdragon, I was really impressed with the smoothness and fluidity of Note 4 but this one thing and the Recent Apps lag. When I clear the ram it gets bit better.
So Actually problem could be of excessive usage of RAM which is tooo much! with no app running on front ground it uses 2GB RAM, I am attaching the photos of my RAM Status with all the apps open and also with no active apps, so if you guys can see and let me know if it is just me or its serious problem with Note 4.
Thanks
I have learned from reading the treads that Unused RAM space is a waste. My Exynos is showing very similar RAM usage to yours.
Do you experience the camera app lag as well?
Sent from my SM-N910F using XDA Free mobile app
Recent Apps lag - yes. Probably get solved in Lollipop.
Camera Apps lag - no but after taking photo and preview slow open - yes it is extremely.
My RAM usage is usually 2.4 out of the available 2.7, this was very worrisome when I first got the phone but I just kept using it without debloating and I don't notice any slowdowns, delays or lag. Yes, the recents menu sometimes takes about 200 ms to appear compared to the usual 20 or 30 but it's not a big deal, it's barely noticeable, the home screen doesn't have to redraw after playing Real Racing 3, Chrome opens up in about 1 second (which is a HUGE difference, compared to the 6+ seconds it took for my S3 to open) and there's no delay when opening the dialer or settings apps like it used to on older Touchwiz devices.
At the end of the day, I simply forget about it and just keep using my phone, it's been performing better than expected. :good:
I debloat the **** out of my N910U
Turned off every app that can be disabled except essentials
(root) Used "disable service" to disable everything that has nothing to do with my usage
(root) Greenify everything except chat app
forced uninstalled all google app
I am still on stock rom and tw, UI smoothness and battery is much better than stock
but that recent app lag is still present so i dont think it has anything to do with ram
I dont feel camera lag that youve mentioned
I have my phone for about 3 months (i think) and it was working perfectly. Smooth, without any problems. I was using it for some small games (CoC) and social media (Snapchat, YouTube, Facebook). Well, it WAS working perfectly. Everytime I was clearing RAM (closing apps) it was showing that about 800-950MB of RAM were free. Now, after updating to Android 7.0 it changed. It shows about 300-400MB of RAM is free (without any app opened). I am also lagging as hell (specially in Snapchat - it freezes almost completly). I was trying to clear it anyway possoble, uninstalling apps, using stock File Manager trying to optimize system. It didn't worked.... Does anyone has similar problem and/or has some solution? Thanks...

tbh, for me android i did opposite. more ram free and 5% increase in antutu score.

More free RAM doesn't mean more performance. It's a bad habit to clear your RAM. Apps that killed will just come back and more hungry for RAM. Continuously doing this will put strain in the CPU and thus, will drain more battery.

I recommend uninstalling bloatware and keep minimal number of apps . This will save more ram and more juice . Dont use any task killers as they are themselves battery havvoks
My Snapdragon S10 is having a weird issue with RAM management. Over the course of a full day, basic apps like the Phone app or Textra will be closed and will need to be refreshed in memory when I open them.
I look at RAM under Device Care and there's around 5.5GB used and 1.9GB free. This is much lower than the free RAM I got on my Note 9 which usually has over 4GB free at all times.
I have Adaptive Battery disabled in the Battery settings as well. There's nothing that should be closing all my apps in the background.
Anyone else get this problem?
Think a few of my apps, like Twitter and Samsung watch app are having this issue.

I'm down to 1GB of free RAM now on a 8GB phone...
Apps opened in background right now:
Phone
Textra
Whatsapp
Kiwi Browser
Gmail
Google Photos
No games and no heavy apps. How is the free RAM so low? And in a few hours all of these apps will get closed and I'll have to reopen them.
Anyone else with this problem? How much free RAM do you currently have? And not off a fresh reboot
I have the 12gb version and have been experiencing this. It seems to clear some apps if the phone has been on staying for a couple hours.
I have the same issue. The phone becomes really slow after like 2 days of use and had RAM usage of 6.8GB. I checked in Developers settings and it says that AndroidOS and systemUI use both 5.7GB?!?! Any fix or should we report to Samsung?
I have the exynos variant and apps never close for me. Currently it's using 4.7gb out of 8gb with 14 apps open.
I checked if the apps reloaded and they didn't. Under developer settings it says that the OS is using 2.2gb, Android is using 297mb and systemui is using 246mb.
Adaptive battery is on and uptime is probably 4 or 5 days.
