[Q] RAM usage...

My RAM is always at about 250/328MB
Is it possible to lower that amount used?
Would it help speed things up a little? Wondering if that would help with the problem that sometimes when I back out of a program or app or hit the 'home' button all that comes up is my background pic and it sometimes takes 20 seconds or so for my apps to appear on the screen.
My 'home screen' just has the Samsung widget Program monitor on it and I usually try and keep that at 0 so Im not running programs Im not using anymore.
Thanks

I would avoid that as it will likely cause problems. Android will have a high memory usage when everything is running fine and normally. It leaves frequently used apps in memory so it takes less time to open them when you need them. It will also free up and allocate memory automatically as needed. If the system gets low on memory, it will free it up from somewhere else. Task killers will just create lag as they will close stuff that likely should be running, or needs to be running. Killing them just creates lag by forcing them to restart. Same goes with other applications, like the browser, email, gmail and messaging that people likely use frequently. Killing them will just make it take longer when you go to open them up again.

not totally true...if you know what you are doing then freeing memory by killing apps that you don't use everyday makes machine run smoother...installed about 400 apps which caused auto start ups to cause machine to run super slow with about 40-60 megs free.

Just hold down your home button, there's a task manager built in... end all of the apps you aren't using.

True but I was thinking more about processes...rss doesn't work right now so I kill the two processes...stuff like that and gtalk and skype

the best thing to do is root your phone then get an app like titanium backup and freeze the bloatware or the apps you dont use. i have done this and it has freed up something like 20-50 mb of ram

While that is true, if youre smart about the apps you kill,you'll extend your battery life and increase your ram. Dont kill things like task manager, voice command, and any widgets you're using. like imnuts was saying, if you kill those apps, youre decreasing your battery life and create lag because theyll reopen on their own and are essential for the phone to run. U want to kill things like phone, messaging, facebook, cachemate, and other things that dont automatically quit when u exit them and arent essential for the phone to run. once ur finished with them and dont need to use them again u can kill it. The task manager that comes with the phone only detects apps that are left open using the home button. Also, dont use live wallpapers and widgets u dont use. Use setcpu and a debloated rom, and that should help as well.

S4 Keeps Freezing

Hi all,
My S4 (4G 16GB Snapdragon) keeps freezing when it is locked, e.g. in my pocket, on my desk at work etc. It also sometimes freezes when it is charging overnight. It was doing this non stop but after I deleted AVG it seemed to have stopped. This morning my phone froze again while it was charging overnight. This has become a critical issue not only for the phone, but for me since I use the alarm to wake myself up for work.
The apps I have downloaded include:
-Advanced Task Manager
-Real Racing 3
-Air Navy Fighters
-Flashlight
-Viber
-Whatsapp
-Speed Test
-Skype
-My data manager
-MTR Mobile
-Facebook
-Personal Notes (not sure how this got onto my phone).
The phone is not rooted and using the standard operating system.
Has anyone had any similar issues? Is it perhaps one of the apps which could be causing this? I'm going to start trial and error process of deleting 1 app every 2 days to see if the issue continues. It would be great though if anyone knows the answer straight up, so that I dont have to spend a long time trialing the different apps. Perhaps it could be an issue with the phone itself and not the apps I've installed.
- This also leads me to my next question, is it bad for my phone or battery to be plugged in and charging all night long?
Thanks everyone
Rob

-Advanced Task Manager ???

Come ooon Bob why you need a Task Manager?
You have already pre-installed stock one.
I recommending to factory reset all phone with full wipe on internal memory. (copy important files before)
Don't use Advanced Task Manager. It was many debate why this apps is bad

Wow thanks for the prompt reply.
I didn't realise my phone has a pre-install task manager. How do I access this?
Does that mean that theres absolutely no point in having a "non standard task manager" installed on the phone?
I have done a factory reset before, but that didn't change anything. So you are pretty sure its the task manager that's giving me trouble?

Hi Robert. If you interesting about it, I recommending to you read this one of the many threads
Proponents of task killers notice that Android is using a lot of RAM – in fact, Android stores a lot of apps in its memory, filling up the RAM! However, that isn’t a bad thing. Apps stored in your RAM can be quickly switched to without Android having to load them from its slower storage.
In summary, you shouldn’t use a task killer – if you have a misbehaving app wasting resources in the background, you should identify it and uninstall it. But don’t just remove apps from your phone or tablet’s RAM – that doesn’t help speed anything up.
Empty RAM is useless. Full RAM is RAM that is being put to good use for caching apps. If Android needs more memory, it will force-quit an app that you haven’t used in a while – this all happens automatically, without installing any task killers.
Task killers think they know better than Android. They run in the background, automatically quitting apps and removing them from Android’s memory. They may also allow you to force-quit apps on your own, but you shouldn’t have to do this.
Task killers aren’t just useless – they can reduce performance. If a task killer removes an app from your RAM and you open that app again, the app will be slower to load as Android is forced to load it from your device’s storage. This will also use more battery power than if you just left the app in your RAM in the first place. Some apps will automatically restart after the task killer quits them, using more CPU and battery resources.
Whether RAM is empty or full, it takes the same amount of battery power – decreasing the amount of apps stored in RAM won’t improve your battery power or offer more CPU cycles.
hope u understood.
Also samsung included a stock task manager.

Thanks Avetny, there's alot of great information there.
Both your comments and the link make complete sense. I actually never realised that Android doesn't perform in the same manner that windows does.
I've deleted the task manager after your first comment. My device is actually running faster and the battery is more efficient too.:good:
I really appreciate you going to the effort of sending the links/information/photo.
I'll report back if this has fixed my freezing problem.
Thanks again :highfive:
Rob

You are welcome Rob. Stay tuned

Fortunately the phone has not frozen since, both the battery efficiency and response time has significantly improved

What is App Optimization exactly?

Ok, I just received the N910FXXU1COJ3 OTA on my DBT N-910F with all the security updates. Great, but I did notice that the conveniet app manager feature that killed background processes inside Smart Manager is now gone and from the looks of things, there is a new "alternative" ambiguously called App optimization, within the battery section.
Now I for one am getting pretty tired of this inconsistency and constant feature swapping and come here seeking information. Can anyone actually clear things up for me and explain what exactly App optimization means. Will it simply kill the apps background services and if so, why is the minimum timeout 3 days? I also heard that it is more like a disable fuature for the selected apps, meaning no activity whatsoever, like notifications.
Is there any way that i can make use of the convenient "garbage collection" that Smart Manager used to offer, or am I hopelessly stuck dealing with Samsung`s ADD?
Thanks, any assistance is greatly appreciated.

Ok. I have a call recorder. It just happens to stop working after awhile. I went to app optimazation and disabled it. Does that mean now that my Call Recorder app doesn't apply to these rules and should never shut off or stop working if I disabled it for that app. It's so annoying because all of sudden your looking and your call isn't being recorded. I have to open the app...then it works again. Am I using the app optimazation option improperly?
When I bought the pro version; a message appeared explaining to disable app optimazation for the app so it continuously works. Is this right? And I'm just dealing with an app problem or I'm I not using this feature properly. I want my call recorder to always be working. [email protected]

App Optimization is Doze mode, that simple

You have to disable App Optimization for apps that should always run in background or be accessible without opening the app itself like Tesla Unread, Torchie, some reminder apps an some e-mail apps. In my expirience if an app is being optimized it will not show any notifications and such until "acitivized" by opening the app itself.

Apps that I don't need running in background and have used more battery than I think they should when in background are set to "Always power saving". Exaples: 9GAG. Previously I used Greenify for these apps.
Apps that need to stay active at all times are set to "Disable for". Examples: Reminders, Tesla Unread.
Most of other apps are set to "Automatically optimising".

This.
This feature can also be found on aosp based roms like cm13.

i cant find some apps in the optimization list (like whatsapp) and messages comes really slowly !
Any suggestions?

Questions about battery draining...

Hello, I have got the Note 4 you see in my sign..
I'm wondering why my Note 4 has this heavy draining mainly by 2 processes (Android System and Android Operating System).
As you can notice in attachment the processes I said drain about the same percentage of Screen On.
What do you think about this issue?

2 ppl already said cleanmaster unnecessary as we already got smart manager. imho, all apps alike clean master / antivirus are unneeded in smartphone.

I'm sorry..I was wrong in my previous post when I asked which app do you suggest me. I meant to say CCleaner but the answer I think should be the same.
To be honest I deactivated the optimisation app for battery in Smart Manager. But now I'll enable this feature.
However I noticed Smart Manager for junk files is powered by Clean Master (you find written that next to unnecessary data in Smart Manager).
I don't remember if I've ever resetted my phone (probably only some wipe Dalvik cache) but I wouldn't like reinstall all things and I should spend a lot of time to recreate folders, shortcut, etc...[emoji27]
You consider that I don't have root access for use of Titanium Backup..
Sent from Note 4 device - Rome - Italy

CCleaner should not affect your phone to this extent. It's not the problem.
I find that Google Framework services are the problem.
Look for both the newest Google Play store AND Google Play Services apk online (apkmirror or androidpit) make sure you get the right ones for your phone - they'll tell you how to check.
Go to App Manager and clear caches for these apps or disable if you can.
Install the new ones.
This may or may not work, it's hit and miss. I had the same problems with my S6 edge +, and this did it for me.
Some people don't like cleaners - I do. I use 360 and Greenify and at times, Deep Sleep Battery Saver.
And I use SdMaid for deep cleaning.
Shutapp and Doze work very well for my LgG4.
Whatever people say, I have increased performance with these apps, and with Greenify I have extended battery during screen off - I've tested it extensively.
The key to improved battery life in all cases is to fine tune your 'white lists' and to be sure that these apps THEMSELVES are not running in the background.
With the apps I've mentioned there's no problem, I've never used CCleaner on my phone.
The Battery optimisation that comes with Samsung is VERY good though. You must make sure you go through ALL the apps and select 'always optimising' except for those few (clock, calendar, Nova AND the external optimization apps you have installed, i.e. CCleaner in this case) which you select 'never optimising.' It makes a big difference.
You'll see that Google Framework Services cannot be optimized.

Google Play Service consums that percentage as it's shown in picture I shared you.
I worried about that two processes of Android System with a very high percentage.
In my phone I have a very large battery by Zerolemon and I don't mind to deactivate some processes like background apps.
I don't know how Samsung Optimisation works and for now I setted Optimisation every three days for all apps.
@kolembo
Why do you suggest me to exclude optimisation of clock, calendar, et. apps?
Sent from Note 4 device - Rome - Italy

I want to thank you all because after the optimisation (Smart Manager) the battery discharges very slowly..and with this large battery is very quite!
But how does it work Smart Manager?

Auto-close apps.

Hello guys, i have a problem with the Axon 7. When i turn off the screen for a longer period of time(10-15 miuntes) and then turn it on again, i get the massage:" unused apps auto-closed during Screen locking".
It seems like it deletes all cashe from the running apps. For example the video i paused in youtube disapeared in the app. This is pretty annoying. Do you have this issue, too?
I hope someone can help me. Thanks.

Would be very nice to be able to disable this bloody thing!

Maybe you can opt to not have it optimized by the power manager in settings?

Is this exclusive to the US version? Only have used mine for a day but never saw that.

It's an option on the power managment. Disable the second setting under power managment.

ZTE is actually thinking this is a feature. It doesn't activate itself for apps that were installed pre-upgrade, but I installed instagram today and it does by default activate the "clean lockscreen" thing which means that it will close the app. The problem is that for system apps, you cannot change the setting. It's a bad implementation of a useless feature.

That's horrible I feel like that's return-worthy. Are you still within your return period?

I've only had it for 3 days, so I still have 27 days to return it. But I strongly doubt ZTE will keep it that way. Maybe @rikin93 can get ZTE to do something about it.

The RAM Management on the Axon 7 is too aggressive! I've got the european Axon 7 quartz grey model (A2017G, update B03) and whenever the screen is off for longer than approx. 5 minutes most/all apps I had open are auto closed. I've searched all settinigs (maybe I missed something) and did not find a way to disable this behaviour (at least for some apps). It is pretty annoying to wait for apps to relaunch and should not happen on the Axon 7, having 4GB RAM!
My previous OnePlus One has 3GB RAM, did not auto close any app like Chrome anywhere near as aggressive as Axon 7 (some long unused and big apps are still closed relatively soon).
Is there anything I can do or do I have to wait until ZTE decides to change this behaviour on the Axon 7?
