So I rooted my phone got lagfix.. And mu phone has been very glitchy...getting stuck on screen.. Touch screen sometimes stops working... Sometimes I programs force close themselves... So I started removing bloatware vz crap tetris n4s.. I'm benchmarking 2155 but its like the phone ran better b4.. I've notice my ram is sometimes droping down to like 50 60 left.. So I task manager and end all apps.. And advances task killer end everything.. And my ran avl. Goes to like 136 and in five minutes its back down to 50 60.. What is going on?

Dont run task managers for one. And anytime you have > 40mb of ram, you should be fine. Try removing the lag fix and see where you are at after that. then try removing root. If this doesnt fix your issues take it back to VZW.
I'm not trying to argue.. But why shouldn't I use task killers? And my phone came with a task manager?

I had the same problem, not after rooting, but after doing the lag fix. I removed the lag fix this morning, and so far it's been all smooth sailing. The screen responds as it should, no lockups, no FCs.
Im a little sluggish too after root. No force closes but laggy when scrolling. Whether its changing screens or scrolling web pages. Not too bad just annoying since it was good before root. Lag fix didnt help so I deleted it, but I may try it again. So sure of the problem.

This may sound confusing and its so hard to explain, especially with just text but I'll try to explain the best I can.
Let's say android os is a chalk board and when you open an app the os writes on the board, some apps he writes more than others. The more Ram you ha e the bigger your chalk board. Now when the os gets to the end of the chalk board it simply erases what it wrote at the top and writes in its place and keeps going.
When you kill the tasks you are erasing the whole board that the os wrote on. So now the os has to rewrite what you erased ( killing battery and taking time) and im assuming after you kill apps you are opening another so its trying to write with two hands (multi tasking) and making it seem to run slower.

Also just plain rooting shouldn't do anything to make your phone run different, honestly it must be the "lag fix" that is messing things up. A good quadrant score doesn't mean a faster phone
Sent from my ADR6300 using XDA App
thanks wisenick.. that def makes sense... with your chalk board explination..lol.. and what exzactly is my quadrant score then? and what does lag fix do???
This is a good example of why quadrant scores mean very little in the real world... Im not entirely sure what the lagfix does, it obviously has to do with the on board memory and data. The memory scores in Quadrant skyrocket after the fix because whatever test it does is largely effected by the lagfix. But this doesn't mean that the phone will perform better, quite the opposite in my experience. The lag fix did nothing but make my phone lag and give me and huge quadrant score. Ill take stable real world usage and low quadrant score...
im with you on that on.. 4 sure... so do i just load up lagfix and click uninstall to get rid of it??? or is there some other way.. ive read of ppl doing it that way.. and not getting there memory back?
Removing the lag fix helped me a lot, but I still noticed the unlock screen would hang up a little. I just did a factory data reset, and wow! Everything seems to be working like a well oiled machine. And for those who are wondering, doing the data reset will not unroot your phone.

I called Verizon today regarding my battery life (at work which I started today I get sh*tty reception which kills my battery in 4 to 5 hours--usually last a full 12-14 hours pretty perfectly). The rep that I talked to quickly realized that I knew what I was talking about tech-wise and thankfully didn't treat me like an idiot.
She said something that got my attention though: she said HTC recently (as in the past few days) released something to Verizon reps saying that Task Killing apps actually interfere with the system and code in a way that drains battery *more* on the Thunderbolt than any other device thus far.
Anyone else heard of something like this or have a reason why it would do this?
*edit* I'm looking for like a dev answer to this... How it interferes with the system? I've seen the threads that explain how it messes with the Activity code but it seemed like it was more than that for the Thunderbolt.
Haven't gone a full day with ATK uninstalled but I'll try tomorrow and see how it goes.

they told me the same thing but not about the battery drain, just that it screws with the system
but on other phones (droid 1) they highly recommend using task killers.
obviously two different phones/companies, but still you'd think they say dont use them for all phones, not just certain phones, because most people feel they are useless.
But it hasn't screwed up anything that i've noticed, and my battery has actually improved since day one, so i think it depends on your phone. And i dont think my improvement is from task killers, i'm rooted and i think custom kernels and roms have helped increased battery life.
Id say whatever works for you do it, and dont worry about the task killers ruining you phone, but if you find out they are then dont use them.
good luck
I would guess that they'd negatively impact performance. The only reason you'd need a task killer is if you were on a 1.5-6 device. In all later version, tasks are managed natively as part of the core os.
One problem is with people using them to auto-kill apps far too aggressively. If you're constantly killing apps that are constantly re-launching (such as clock/weather/SMS/MMS/news/widgets/etc that tend to stay resident), you're going to end up up using a lot more processor time, and thus battery life, than if you just let the apps sit idle.
I heard that its because Android 2.2+ automatically restarts apps that you close and then it uses more memory to restart each time it is killed. There is a built in task killer in the phone anyways. No need for a secondary killer. But from my personal experience: yes I got worse battery life with task killer than without it. Although on my Droid x it was the opposite. Must depend on the phone

Your explanation is off a bit but you get a C+ for the spirit of it.
In short, Android use your free memory to cache programs into using spare resources. ATK then removes these apps from this free memory, making it free again. Android then uses your free memory to cache programs. Then ATK. Then Android. Etc... See the problem? Slows down your system and wastes battery doing it. You are correct in that there is a built-in memory-freeing system that does this really when it's needed. There are ways to influence how aggressively it frees memory up.
The reason it helped with your Droid X was because of how pathetic Blur was. With custom roms that removed most of Blur, ATK hurt a lot there as well.

+1 thank you... didn't feel like explaining all that
one thing to add for all you wondering...ram will use the same amount of power whether it is full or empty so don't' worry about using up all your ram...the android os will kill off apps and caches as needed to keep you running fast and efficient. our batteries life sucks because we use our phones so much or because (like me) we run beta software with bugs.
i've tested numerous times and sitting idle overnight (about 8 hours) on 4g OR WIFI, i will lose between 4 and 6 percent.
Quit muddying up the dev section! This has nothing to do with DEV!
This should probably be in the general section, and yes active task killers will ruin your battery life, if you have it uninstall it. The only way you should ever force close running apps is with the app management built into the android system and thats only for rogue apps that never stop running.

on droid x wit blur atk still hurt battery life. only worked on eclair.
One thing that I have encountered in supporting VZW technical issues, in addition to battery life, over-aggressive task killers, if not configured properly, can kill necessary apps. People call cause their alarm clock didn't go off, they didn't get text messages for 30 min to an hour, etc. Some of these programs *need* to run in the background.
Yeah from what I understand its not the phone but the os. On eclair task killers helped out . But froyo and gingerbread both take care of all of that in the back ground and using tk's affects the way the two os's are working. I was told all of this back on my Captivate and at the time I was hooked on task killers and Froyo leaks were just coming out. My batt life sucked and a dev some probably know , Designingears , explained all this to me and omg it was hard for me to take in and delete advanced task killer lol. But I did and have never looked back and it definitely improved my batt life. Now every now and then you just get a stubborn run away app that the os just can't stop, can't remember the app but theres a couple out there that take care of this and there not task killers. Me, I just reboot my phone every now and then and all is well .

so from what I've learned being in the business for 6+ years. The task killers kill everything where android needs certain things to run so your system doesn't lag. That being said a lot of the manufacturer are including a task killer in there new roms to over come this issue. Example the new droid x 2 has a new task killer app. Motorola was the first to say to Verizon no task killing apps and now HTC follows. Wont surprise me with the gingerbread updates to android phones if you see more companies build task killers into their roms. I stopped using a task killer last week and battery life has increased. Just my thoughts and opinion.

I second that. When I bought my Thunderbolt the clown at the store told me to put a task killer on it. I did that it killed the battery...On Perfect Strom 1.4 I am getting over 10 hours with out a task killer. Not scientific but I consider 10 hours good for battery life on this phone
Day 1 when I bought the TB a HTC rep was in the VZ store and he was saying same thing then about task killers worsening battery life and performance

exactly.. froyo and GB do the task management job well.. when I had my droid 1 running 2.0, i compared with and without a task killer, and battery life improved a little when I did use task killer. But then with froyo and above, it would actually make it worse to use one..
Me thinks that the phone processes is set up to where a simple task manger can kill them, thus messing with some essential processes. Which in turn, would make the phone have to use a little bit more juice to start the processes back up over and over.

Atk initially "sounds" good because most of us use to windows OS. Atk would/could be of use if droids ran windows... Droid is based off Linux and if you read up on how Linux operates, there is no need to constantly kill apps when it doesn't draw on system performance while in the background. Where the problem is, is that some apps have permissions to chill in the background and by killing them and the system brings them back up, just to be killed again. Not gonna drag thus on because I'm typing on my phone, but atk's aren't necessary.

Thank you in advanced!
Sent from my T959 using xda premium
maybe it have a software on market but i dont remember it
Nope. From the factory we have a misleading 512mb. I say that due to the fact that something like 170mb is automatically eaten up by the Android system. Leaving us with a meager 340mb. In the beginning kernel makers were tweaking the amount we had available but it left other things broken. We can never have more ram available without ruining other processes. And adding a new chip of ram like a pc is absolutely out of the question. May I ask why do you need more ram? Are your homescreens widget city? I've needed to compromise which widgets I use but thanks to circle launcher makes it not half bad.
Sent from my T959 using xda premium
One of the things that I do when I flash a new ROM is delete all the /system/apps that I do not use. Well, delete isn't really the right word. I move them over to a folder on my external, so just in case I ever want to reinstall them, I can just move them back to /system/app, wipe Dalvik and reboot and viola they are there. Another thing that I also do is if I don't know about a certain app and what it does, I'll use TBPro to freeze it and wait for a few days to see if there are any adverse effect. If not, then I'll uninstall, If so, then I will defrost and make note.
The reason I mention this is, aside from being in widget/homescreen hell, there are system apps that you may not need/use that are running and taking up unneccessary RAM. Example: If you never use Maps, then move it out and that service (locator- I think it is) won't be running in the background.
There are times that I opened a lot of apps,some still runs in background even if i already closed it and it decreases the performance of my phone.. I have a friend who have a Samsung Ace and he was able to add up memory of his ram..I did the same thing and it just adds up on my internal SD... just wondering if that is something to do with tweaking.. by the way I'm on MIUI

Any of the "hacks" to get more memory on this phone will result in either lower performance or breaking something or both. That's why there's not anything around for "increasing" memory.
Any by the way, he probably added a swap partition on his phone, which NONE of the roms for vibrant support/have implemented.

Well try what I do. Im using startup manager and blocking which apps are allowed to startup without me starting them. Start up cleaner is free and appears to do the same thing. Much better than freezing in titanium because they are still useable. A VERY few apps might start up anyway but who cares you will be in much better shape overall.

What are some first steps I should take to figuring out what is the culprate to causing this lag?
Clear some cache? I did a battery pull. I dont see anything Seriously abnormal in cpu or gsam. Help walk me through a couple steps please!
Different phones run different ROMS differently, even if its technically the same phone.
I'd suggest trying other kernels.

Get rid of apps that aren't commonly used. I clean out my phone and SD card every month or so from all of the apps/games I try out. IME monitor and battery saver apps do far more harm than good. I also noticed that Facebook is causing all sorts of problems for data connection and performance on all my family's phones (2 TBs, 2 bionics, and a SSGS).
IMO, CM7 is the best daily driver TB has seen. I ran it for almost a year with no issues. Its not flashy or new but its super stable on our TBs.

Firstly, you need to face the fact that 2GB was a bad decision by Google for this tablet. There is nothing that we can ever do about that. :crying:
If you want to stay on stock, Chrome is the main culprit in consuming Ram. Switching to Habit Browser makes things better as well as changing your DPI to 288. Do a search on XDA regarding this. Whilst it improved things, it was still not enough for me.
I snapped a week ago and have now rooted and flashed CM13 and stuck with Habit. I've been using a few days now, and for the first time, I can keep my 3 Fantasy Premier League Tabs open, (they are huge,) without constant refreshes, redraws and lag. :victory: Right now, I feel for the first time, I'm getting what I paid for and the Nexus Experience. The only bug so far, is that always listening doesn't work.
If you've just bought this tablet, I'd consider returning it if you are not prepared to root. The performance will never be acceptable on stock.

Clearing dalvik cache will do precisely ONE thing and ONLY one thing; make it take a long time to boot next time as it regenerates it.
Ignore the amount of available memory. People who are concerned about the amount of free memory are trying to apply bad mswindows knowledge to Android. Totally different and no comparison. UNUSED MEMORY IS WASTED MEMORY!!!
So here is how memory management works in Android; it *preloads* everything that it thinks you are most likely to actually use, so that when you DO use it, it is more likely already loaded and starts up very quickly. If you are switching to something that is NOT already loaded, then it just needs to dump lower priority programs out of memory, which basically only takes a few nanoseconds (billionths of a second). So that is NOT it.
If your device is acting slowly, then you need to figure out what the actual cause is. Trace the CPU utilization with something like the "top" command (the one with busybox is a lot nicer than the one that comes with Android) while you are experiencing slowdown. You can also look to see if there is excessive I/O happening (i.e. read/write to the internal storage), and of course, some software will require a network exchange before it will start up -- nothing you can do about network lags.

You can do some investigation by watching the processes and seeing which are taking the CPU and memory on stock. The problem is, when you find out, there isn't much you can do about it.

Its quicker and easier to just install a custom rom where this type of work has already been done for you. :victory:
Lately, I've discovered that loading Chrome immediately raises my CPU temp by 30+ degrees. Sometimes that's enough to make things run really slow
Yeah, I agree...I will try to fimd sometime amd go over flashing a custom rom. ??
Yes! I habe noticed that these slow downs mostly happen when I am browsing in Chrome...
Web browsers are DEFINITELY a source of slowdowns.
The problem, more often than not, is actually *javascript* that is written by MORONS. Even on a desktop machine, you can watch the web browser for CPU and RAM utilization, and it just grows and grows and grows until you finally kill the process and start a new one.
What this may come down to is actually quite simple; the CPU in the Nexus 9 is actually more suitable for use as a stovetop than an actual CPU. These things get way too hot way too fast. If you beat on them with a web browser, they'll get hot and throttle down to low/verylow frequency, which will make them generally unresponsive. So if that is what is happening to you, there really end up being a few options to deal with it;
1) disable javascript in the browser,
2) don't use the browser,
3) improve the ability to disperse heat from the CPU.
For #3, you may note that when it gets hot, it is pretty localized to the corner of the device up near the power button. An easy solution to distribute heat better might be something simple, like adding a layer of copper foil to the inside of the back cover. The thicker the copper foil the better. Copper is very good at conducting heat, so this would spread the heat around over the entire area covered by that foil. http://www.ebay.com/itm/Copper-Foil...nductive-Adhesive-Ship-from-USA-/162018486132
I also found chrome was slow starting up, switching tabs etc. Found that logging out of my Google account in chrome improved this. Seems that synching tabs etc triggers the pause. This might be an acceptable workaround for some but I appreciate it isn't a great fix if you want to use that feature. Actually I'm not bothered as I think Google know too much anyway. �� But the underlying problem is this tablet... I don't have this problem on my phone.

Web browsers are DEFINITELY a source of slowdowns.
The problem, more often than not, is actually *javascript* that is written by MORONS. Even on a desktop machine, you can watch the web browser for CPU and RAM utilization, and it just grows and grows and grows until you finally kill the process and start a new one.
What this may come down to is actually quite simple; the CPU in the Nexus 9 is actually more suitable for use as a stovetop than an actual CPU. These things get way too hot way too fast. If you beat on them with a web browser, they'll get hot and throttle down to low/verylow frequency, which will make them generally unresponsive. So if that is what is happening to you, there really end up being a few options to deal with it;
1) disable javascript in the browser,
2) don't use the browser,
3) improve the ability to disperse heat from the CPU.
For #3, you may note that when it gets hot, it is pretty localized to the corner of the device up near the power button.

Yeah, they do get hot...and the browser is the problem, I agree...however, I think they are not the main reason...there is something wrong with low memory or maybe some apps...

I don't agree with that.
We use our N9's *all of the time*, and there is never any perceptible slowdown. Possibly with the exception of straining them with web browsers, but web browsers are... poopy... on EVERY platform and device, so that doesn't really stand out. Typically just minimize the use of web browsers and all is well.
Web browsers were good in 1996 when they were simple things to display an html website. Since then, they've added all kinds of useless crap to them that bloat them out, hog up tons of memory, and just generally make them into a useless waste of space.

I know..but everyone knows that N9 should be faster!...

Update:
I think I have kind of find the problem of low speed of my Nexus 9...I uninstalled an app that was for weather prediction and from that time on my Nexus 9 is very fast and responsive...No problem so far. I also uninstalled some other apps alogaide that which I was never using them,so I am not sure if the weather app was exactly the reason of the slow downs...but the other apps where just some games or some simple apps....well, I hope this information helps! Let me know your idea. Thanks everyone
