[Q] Clearing RAM

Whenever i clear the ram on the phone, it seems to move all the applications on my home screen around, making me put them into their places all over again. Anybody know why this is happening?

Well this is awkward a bit
Try to use the stock ram cleaner & tbh i never encounter that issue atall

that;s the one im using, the stock ram cleaner, when you hold down the home button, bottom left and click on RAM then clear memory. That's when it happens :S

Know the Difference Between Good and Bad High RAM Usage
"Sometimes people like to panic when their computer's resources seem to be maxed out. While CPUs and hard disks may suffer from high usage, RAM doesn't necessarily slow down your computer when it appears to be running low."
http://lifehacker.com/5958598/know-the-difference-between-good-and-bad-high-ram-usage
Whether your RAM is full of cached files or completely empty, it's all available for programs that really need it. Cached data in your RAM is marked as low-priority, and it's instantly discarded as soon as the memory is needed for something else. Because this data can be instantly discarded when necessary, there's no disadvantage to using the RAM for cache. (The one potential disadvantage is users who don't understand what's going on becoming confused.)
Empty RAM is useless. It's not any faster for the computer to write data to empty RAM, nor does empty RAM use less power. In fact, assuming you're launching a program that may already be present in your RAM's file cache, programs will load much faster when your RAM is used rather than when it's empty.

You mean to say it refreshes the whol3 screen after you clear ram?

tbh, when i cleared the ram, it would remove dolphin browser and the stock msg app into the all app folders for some reason. si id have to put them back to their place every time.

UK G3 memory

Well I've got my g3 and after 2 days use I've noticed that with its 2gb memory it constantly uses 80% of it even on standby with no apps open. I did a factory reset and didn't install anything and it was still using 72% of the memory. Anyone else noticed this or is my phone faulty.......?

I think this is how Android works, it fills the memory then kills things it doesn't need. There's also ZRAM active in the kernel which uses roughly 25% of the memory as swap space.Heres a snippet from an article on Android RAM....
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a*good*thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.

Its not so much Android as how Linux manages memory. The memory usage indicated includes memory used for cached apps and information, or swap etc. In saying that LG's version of android does use more memory than stock AOSP android on say a nexus 5 (1.2gb~ on G3 compared to around 700mb on N5)
But the rule still stands true, used ram is better than unused ram.

free ram is wasted ram.

So? What's the problem? Using RAM is good, it's what it's here for. Android will try to keep in memory as many apps as possible, and when it's full, it'll start killing old apps to free ram for new ones. Don't worry about that, it's how it's supposed to work, and Android is very good at that. You should never have to worry about killing apps yourself, and you won't see any bad performance impact because of high RAM utilization. These "task killer" apps out there (including the default one on your phone) have only one valid use case: killing an app that's not responsive, in a connection loop, or that you wish to manually reset for any other reason.

Well thanks guys for your replies. Had no idea that's how android worked. Just goes to show you learn something new everyday.

[Q] RAM Usage

I've been noticing some slight lag in unlocking, the screen coming on, etc on my new Note 4 from time to time. I've found that going in the app switcher thing and clearing all remedies the issue for a bit.
I was curious recently and looked at the RAM usage in that screen and was surprised to see that ~2.1GB of RAM was being used, even after clearing all recent apps.
Is it normal for the thing to be using over 2GB of RAM at all times? This seems very strange to me.
Thoughts?

I'm pretty sure its normal because mine is also using 2GB after clearing all. After a reboot, it dropped to 1.6GB before manually launching any application. I'm pretty sure Android is designed this way.

The way android is made and runs, it uses almost all RAM at all times... Basically "unused RAM is wasted RAM." All of our phones have run this way since the time of I'm.
Now, with respect to lag, that's all the bloatware forcing itself to be the main process or close to it. Only way is to fully delete (not only disable) all of them and their underlying processes.

Thanks for the replies, guys. Just waiting on root, then bloatware will be gone.

Well said..

Only time I have lag on the lockscreen is with a sub par sd card. Once I got rid of that junker the lag went away. Try removing your SD card and see if that fixes the lag.

Note 4 Sprint 6.0.1 Baseband PC1 lags

I bought a used Note 4 Sprint and since I flashed marshmallow using odin on it it gets laggy or reboots from time to time.
Is it something with my Baseband? Like should I install a different Frimware or it's a marshmallow issue?
The battery is okay and the screen is all good as well.
And finally do you recommend me any stable ROM or stock ROM ? Thank you I'm advance

You could likely do better with later Marshmallow releases and possibly custom ROMs if that's your thing. I'm on the PJ1 update running UN7 (Note7) port.
Between, Samsung, Google and Sprint, there's enough bloat on a stock Sprint Note 4 to sink a ship. And Samsung can't optimize the RAM caches well enough to suit individual preferences because it favors its native apps that are baked in as well as other system apps from Google.
This optimization may not favor the apps you prefer to run at will so you need to understand how to deal with it. There's Samsung's version of Doze and there's Android's version of Doze on your Marshmallow Touchwiz firmware. Samsung's version will routinely shut your apps down and doesn't do a good job of real time RAM management while sleeping. It's based on a 3 day run theory but it doesn't my user apps use at all; it shuts apps down that haven't been used in three days. This favors apps that it runs in the backgrounds continually.
So turn that of and focus on Android Doze is my advice. You can find both methods in battery management. Smart Manager may a shortcut to battery management but you can use Settings to find it too. You may see App power monitor on first battery screen; I advise turning that one off. Android doze can be found by tapping Battery usage then tapping 3 dot menu button in top right to goto Optimize battery usage. Once there, the dropdown menu will allow you optimize doze by showing all apps. I disable ones I don't want running continually but enable those that may be impacted by doze with screen off only. If you ever wonder why your music or downloads stop with screen off, here's a place to start. Push notifications should happen anyway with doze active so those may not need enabling to run continually.
You may consider freezing apps that show as running when you don't prefer them to even you're checking running apps. You can use Smart Manager often to optimize RAM or get an app that allows you white list some apps and dump cache for non white listed apps on a scheduled basis.
Personally I find Marshmallow Touchwiz poor for RAM management. The UN5 Lollipop ports managed RAM better without having doze. Somehow I think even the Note 5 may not have good RAM management on Marshmallow. Maybe Nougat is a different story? But I do know that Marshmallow proved to be a bigger challenge than Lollipop did, especially the ports. Why would I run Marshmallow? I guess its inherently faster than Lollipop. But only when optimized, IMO.
I also use Boost+ by HTC found in Google Play Store to free up RAM. Samsung thinks many apps I use regularly aren't being used. HTC Boost+ can discern app use better and logs freed RAM so you know it's working.
As a user, you can discern if these suggestions help or not. Just lag, preferred running apps and battery management advice. They may not be every user and YMMV.
Edit: pay close attention to battery capacity at reboots; bad batteries do have a tendency to shutdown, possibly reboot as well. Last time I had a bad battery, it was on a lollipop ROM; phone shutdown at 30% and plugging in charger showed 0%. Marshmallow may be different; battery is suspect for reboots in Marshmallow. I haven't experienced reboot issues with Marshmallow or have a bad battery to add to this suspicion though.

You couldn't have got a better answer very concise and thought out. I can only add that a bad battery will have the same results as far as shutdowns in marshmallow. Never had a reboot issue. However many have with the earlier builds.

RAM BOOST

Hi to everyone. I'm comming from OnePlus 5t and I don't have any experience with "Ram boost" that we have on Oneplus 7t (Settings/System)... Also I didn't find many explanations by searching (neither here on XDA nor at Google search).
So basically, how it work and is there any benefit except gaming, (and I don't use mobile for gaiming) in real life?
I can't recall is it On or Off by default?
And last but not least, how it's effect battery life?
Thank you.

From what I read, it works like windows superfetch.
When ram usage is not taxed, it will fill the free ram with apps it knows you use frequently. Presumably as with windows, it keeps them in an off state, but when you open the app, it doesn't need to load it in to ram from flash storage, so it can load much much quicker.
There won't be any battery drain.
When ram usage is needed by say a game, it'll kick these auto cached apps out.

I've been using the OP7T for close to a month. I've experienced lag while using various apps, and especially when switching between apps. Occasionally the system becomes temporarily unresponsive, and a handful of apps have crashed multiple times. My previous OP3 phone rarely lagged, even if I had tens of apps open. I've been using the RAM booster on the 7T, but today I spent some time removing and freezing apps that were consuming tens of MB of memory in the background.

personally I didn't had any glitch or lag... I didn't saw any different.
But I don't recall is it turned on or off by default.
Anyway thank you both for comments and making it more clear to.
