[Q] memory usage

Good day!
Im new to xda-developers forum, just found a link in youtube while watching some stuff about galaxy note.
I have not discovered my galaxy note thoroughly yet coz its still new to me. Just wondering, the usage of memory without running any apps will go about 60%-70% percent. My temporary solution for this is to run task application and kill all exciting apps. Just wanna ask what kind of problem this may be?

No need to get alarmed by that. That's the way Android runs: it keeps apps in cache, so you can access them faster. When there's too much of them cached, the system kills off some apps.

thank you for your reply.
in this case, i cannot access on other apps that i'll run. just manually kill all the apps every-now-and-then.

Just remember: free memory is wasted memory. This is true for almost every piece of computing machinery out there.

Thank you.
the only thing is, when i access on other apps like games. loading on the apps takes longer or even it crashes. maybe its because of the memory allocation of the apps or just there is no enough memory space to allocate the app.

While what the other member said is true, unused memory is wasted memory, but the issue is exactly that. Android ends apps that you may be running to be able to open more apps, which I find bad.
While it is normal to find the amount of ram you have said already loaded and being used, I still don't like it.
There are times that I'm trying to multitask and I open an app and right away jump back into the previous app to find that Android OS has decided to close it, within 3 seconds of hitting the home button. It makes multitasking a little harder. But there are ways around this .
But still, I hope ICS fixes this issue. I don't need 200 of the 1 gig of ram in use, what I would like is to have 300 or so free to be able to multitask normally.

can you please elaborate on the workarounds so that Android doesn't kill the background apps especially opera mobile

[Q] Half of my internal storage is missing

OK, so I have no idea what happened. All of a sudden my space was used up. Which I thought was pretty strange. When I look in settings, I'm only using about half of what I have. However, the other half of my internal storage is just unavailable. My tablet knows how much space it has total, however adding up my used space does not yield a number matching my total space.
As long as everyone understands lol, can someone tell me how to fix this?

Anyone?

Try the app DiskUsage to see if what if anything is using up your storage.
Also try booting without a microSD in the tablet. I've seen it that a bad card caused this.

OK, so I downloaded disk usage. Apparently, 11 GB is taken up by Android. This seems strange to me.

Seems you used a different app. I meant the one by Ivan Volosyuk.
But if you have ES File Explorer or File Manager HD, they also can show you what's taking up storage down to the file level.
Either you have a lot of forgotten nandroids on there on some huge log files left over. Dig and drill down...

Ok, so I downloaded the one you meant. And this illustrates the problem to be system data. 11GB of it to be precise. What is in there for me to clear out? And where do I clear it from?

Are you rooted?
If not all the stuff in green is inaccessible to you. I'm running a debloated custom rom and my System section is about 9 GB. Your's is 12 GB (1 mib = 1050 kb roughly). Could well be that non-removable apps (aside from necessary system files) take up the difference. Nothing you can do about that without root.
But I see a pretty good chunk occupying media, especially your Android folder is pretty hefty. That is where your app data lives. The most interesting part is cut off in your screenshot. You got some game installed with a very large footprint in terms of cache. Check out the size of your Android/obb folder!!!! Mine is empty!
Swipe to the right in DiskUsage and check what's taking up the space. Pinch in/out to see details.
Man, this app is great! I'm so glad I discovered it for you
Move anything not crucial like pictures, videos to your microSD. Uninstall apps you don't use anymore, especially games.

Yeah I have root. I am running CyanogenMod on my tablet as a matter of fact. Was a real pita getting there thanks to Asus but I managed with help from XDA.
As for the Android folder, I checked it out, and I am an idiot. GTA San Andreas, KOTOR, Bards Tale. That's 7.5 gb right there. I didn't realize there was so much extra after the fact with them.
Thanks for the app suggestion. I am adding it to me toolbox.

New to Android. Just looking for some pointers.

Hey all. Long time Blackberry user here. I have a couple questions about my note 5 I just picked up.
- Can I root the device (I'm on verizon)? I've done a bunch of googling and so far it seems like verizon has done a good job at making it impossible?
- The main reason I want to root is to just to rid my phone of all the JUNK apps I don't want. If rooting my phone isn't possible, what's the best way to prevent the apps from taking up space and using up data? With no sdcard slot, space will be a premium, and I'd like to free up as much as possible.

Right now without root access on our Verizon Galaxy Note 5s there's no way to get rid of the apps to free up space. However there is a way to disable the apps by using Package Disabler but you have to make sure that you don't disable anything if you don't know what it does because you can end up causing the phone not to work or not boot in which case you'll have to do a restore and lose everything. I actually made the mistake and disabled some things that I shouldn't have and it caused the phone to get stuck at the Verizon logo so just be careful what you do with it! Also if you disable certain things that the system needs it can actually become detrimental to the battery life and make it run out faster. Personally I'd say to just leave it alone unless it's actually doing something because on mine I noticed that if I don't use them or tap into them they won't run anyway.

hi,
Here's a few pointers, what i do (managing free space)
Firstly, i am also on a branded version. No root, stock Rom.
I found that i could uninstall most of my carriers bloatware,
( see... Device /Settings /App Manager)
Other system bloat apps, i just disabled in App Manager.
Check system apps like...
Eg S Voice.. Briefing.. S HEALTH ?, (if you can disable.)
Secondly your stock Smart Manager, /App Powersaving, the apps i hardly use, i set to always... optimizing.
I used to store movies on my ext Sd card, (but as
we have no Ext Sd card) , i keep my movies on
a mini OTG SanDisk. If i want to watch,i plug /attach, OTG and watch.( Saves a lot of space)
Eventually, you just "adapt" to the limited space.
Good luck
Post note,
Root, is not always the answer.!
Sometimes you just create, more problems /issues
for yourself.
All my other devices Note 2/3/4 is rooted.
My Note5 is not rooted and i am overall very happy with device.
I only have 2 x small system bugs, nothing to stress about /root (Found a roundabout way to fix these.)
Otherwise.......
(Battery life is good , Device runs very smooth, optimized good)

Thanks for the response. I've gone through and just disabled all the verizon apps that I could, as well as a few of the samsung apps I feel pretty confident I won't be using. Seems like rooting is more of a headache then I really want to get into right now with a new device, and a brand new platform (I've literally been using an android for 2 days now).
Thanks again!

RAM always at 70% on MI5

Hello fellow MI5 users,
I received my phone one week ago and I start having some issues with the RAM. In fact, at the start of the phone, it's already at 70% filled up which is too much for me. Indeed I use a lot of RAM and I'm that type of guy who let the apps running in background everytime because I keep opening them everytime. I was wondering if it was possible to have a link to a better ROM because I guess it's the problem and also a link for a tutorial on how to flash it I'm a newbie in this type of manipulation but I'm very interested so I hope you will help me guys. By the way, my MIUI version is the MIUI 8 Global 6.8.18. I honestly don't know what can i give as information but I'll answer ASAP at any questions
Have a good day

This is working as design - Android keeps apps in RAM to reduce I/O on resuming from background - faster & more energy efficient.
You can change the number of background processes via the development settings or you can kill apps on closing.

I've seen that indeed but it was set at standard so I'll probably put it at 3 I guess. How should I set the memory optimization? I've read it should be set off, altough I tried middle and I feel comfortable like that?
Is it normal to start at 70% without anything started ?

For the 3GB version? Pretty much. MIUI is horrible.
After booting I typically had 1.3GB / 3.0GB free but after a while this averaged to around 650MB free.

I know that but I need more because I use multi-task a lot. Is there a way to change the ROM so I have more space to work with? Even if the ROM itself is beautiful.
Indeed it's the 3gb version 32gb. It have lags sometimes and I think it's due to the full RAM. Can I have a link to a custom ROM which works fine on this device?

I'm a little confused, you want as much RAM available but you want as many processes in the background as well? That sounds contradicting to me. Memory optimization maps to ZRAM, if you set it off there will be no memory compression and thus even less processes will be kept in the background. If you set it high, you can have as many processes as possible, but there could be lag due to (de)compression time overhead.

Try different Rom
Try to use a different Rom. On the Stock Rom is a lot of bloatware which is using your RAM too.
First you need to get an Bootloader unlock permission and have to unlock the BL.
It could take up to 10 Days to get the permission from Xiaomi
http://forum.xda-developers.com/mi-5/how-to/unlocking-xiaomi-mi-5-bootloader-t3336243
After that you have to flash a recovery like trwp via ADB. Google it for videos or threads how to do it.
http://forum.xda-developers.com/mi-5/development/recovery-twrp-xiaomi-mi-5-t3412123
After that you can flash a developer Rom.
I use the Resurrection Remix and it works fine. The CM 13 stucks in Bootloop. Maybe because I made a full wipe and had to sideload my rom.
Because you don't have a SD card option you have to have the room installed on your hard drive. But just follow the description below
http://forum.xda-developers.com/mi-5/development/unofficial-resurrection-remix-m-5-6-9-t3395945
It took me just 1 day to get the unlock permit but don't try do do it without it. You brick your phone.
The RR Rom works really fine. Fingerprint and everything. It has no bloatware and you have to get the gaps like in the description. Arm64 nano seems enough.
Good luck and fun with a great phone.
Normally the android system kills the unused apps even in background. But i also experienced lack in multitasking.

I think you misunderstood the OP question, he wanted more free RAM at start in order to have as many as possible apps in the background.

In fact, I'm just doing some research before asking because I'm very new. I have found some videos but they are pretty old and not on this phone but I guess it works more or less the same way

OK, in that case, just open Security->Permissions->Autostart and disable those which aren't immediately needed upon start. I have 18 autostart items (mostly system monitoring & social media apps) and I usually start with 1.5 GB free RAM.

Defragmentation option appeared. Wow!

For the first time ever since getting my Mate 10 on launch day, I just received a pop up notification to defragment my phone which will improve performance. I did so. Wow they were not wrong there! Everything is so quick now. Apps launch super quickly! Anyone else had the opportunity to defragment their phone?

Mate 10 non Pro. ALP L29C636. UK.

Stange, I got the same phone and rom version .
All I've got was an update to .132 yesterday....
haven't noticed anything about defragmenting phone......
Where can I find it?
cheers.

Great Post.

I don't think you can find it. It just appears out of nowhere. I guess it depends on how much you have used your storage and delete and save files.
One thing I have done recently is empty the recycle bin folder in the gallery app which had over 30 days of deleted photos and videos. Perhaps deleting the accumulated storage taken up left a big gap in the storage file system. This is purely a hunch. Have no idea if this was the reason I got the defragmentation notification.
I wish I took a screenshot of it now.
Just found this blurb.... Defragmentation is mentioned....
"The HUAWEI Mate 10 and HUAWEI Mate 10 Pro take the “Born Fast, Stay Fast” promise to a new dimension. Leveraging AI-powered Battery Management, the devices improve memory allocation utilization, using different mechanisms such as: CPU Resource Allocation and Management, Run-time Memory Management, IO Resource Management, Storage Management and Defragmentation and Battery Management."

Yup I get a de-fragmentation pop up once in a while.
Still waiting for a firmware popup.

I saw this once and laughed, remembered me of Windows 98.
Android is supposed to support trim, so devrafmantation shouldn't be a thing... Unless Huawei is calling it Defrag but instead they're doing something else behind the scenes.
Anyways, the born fast stay fast BS is based on the system continuously trying to shutdown processes ASAP and keep them from working properly, and it's continuously pushing the user to delete all kind of "unused" files.
So I've a phone with 128 GB storage and 6GB of ram, but I neither can use the storage nor keep apps open in RAM cuz the system doesn't like it.
Wished we could disable the phone manager and its BS entirely.

I agree, that could be the reason apps like Adguard keep getting killed regardless of if its been whitelisted in Phone Manager.
As we approach having a stable TWRP/Root solution for ALP's, (cudos to Pretoriano80) I hope devs would find a solution to the over zealous AI/NPU.

You are full of BS, one of the weaknesses of F2FS is fragmentation decreases performance more than EXT4, so it actually needs defragmentation.

doesnt F2FS do auto trim?

I just got the notification to defragment on my Huawei P10 VTR-L09 and I clicked it, But I was doing something so I decided to go back to it and do it later. I figured I would be able to do a search In the settings to find the defragment option. Well guess what... It is not there. I guess the only way to defragment is when the system wants you to and not whenever you feel like it. I should have just done the defrag when I first got the message. Now I have to wait until it pops up again.... They should give you the option in the phone manager. Anyone know how frequently the defrag option pops up??

Yes a warning to others. If you get the defrag option, you MUST do it there and then. Do not navigate away from that notification as you can't get it back.
