Can y'all help me figure out what's happening to my wife's phone? My wife's phone is getting bogged down. Apps will sometimes force close. We have been told that she needs to empty her cache when it gets up to 1 Gb, about once a month. We've been monitoring it and it fills up in a week or less. Three days ago it was at 2 Gb, we emptied it. Today it is at 0.9 Gb. I don't understand what is going on.
Here are my questions:
1.) Will a large cache (> 1.0 Gb) mess with her phone?
2.) Why would her cache fill up quickly?
3.) Is there anything we can do to make her phone more stable?
We've talked with the techs at Verizon but they aren't XDA.
Thanks.
the cache is not supposed to be filled up that fast. I believe big cache might have a slight negative effect on overall system performance, but this would not be dramatic. The bigger problem here is, WHAT is constantly creating such big data, which no doubt requires lots of computing power.
I would suggest freezing all possible apps and monitor
I would suggest looking going into Settings > Storage > Internal Storage > Apps and go through each app on the list and see how much data is cached. Then you can identify any badly behaving apps and know for certain what is making your cache grow so big so fast.

Using my phone I have tried different methods of installing the latest VanijEclair on my Tilt. However ever since I installed everything on Nand including data I have noticed that I have awsome battery life on a fresh install. I am using 2G all the time also but even with 3G on I get a little better battery life when installed strickly on Nand.
Before I settled on this method I tried installing Sys on Nand and Data on SD and I would go to work have to recharge at the end of the day because my phone would just die. The only thing that I can think of is that even when the phone is off the sdcard is constantly reading and writing data sucking down precious battery power throught the day.
Although when installing strictly on Nand you don't receive the benefits of more space you do gain speed I think as my phone is pretty smooth so far.
Has anyone experienced this?
My view is this, when we flash the NBH, it creates 4 partitions in nand, one for boot, one for system, one for data, and one for cache, ( I think that's correct, please let me know if I'm wrong), anyway, if we install sys on nand, data on SD, what happens to the /data partition on nand? Is it magically transformed into RAM or something else? No, it just sits there doing nothing, you could hack the partition sizes to free up more space on system, by 'stealing' it from the redundant /data partition, but that has no real benefit either, apart from being able to install huge experimental builds, like a hero/sense one I'm playing with, ( no it won't boot, and it's so old it has cobwebs on /system/media).
So why waste that space, I've always used sys and data on nand, and tried to control my bad habit of downloading every damn widget and app i like, because I'm really only going to use once, or maybe twice, and battery life is something that 'improves' with use anyway, ( it's called battery calibration, the longer you use a build, the better the battery calibration gets).
I do think that the ideal set up would be similar to the one I use on my G1, sys and data on nand, ( naturally), sd card partitioned 64,512 swap/ext2, the remaining space fat32, use apps2sd and either swapper2 or enable swap from spare parts, (some builds have that option, unsure if it works on kais tho, something else to play with if I get the time).
The reason why battery life is worse using SD may be that is just less efficient anyway, it's certainly slower, and ties you to that SD card, which is usually fine, but occasionally like to transfer data, and removing the SD is possible if it does not contain part of the OS
half way through the day today, and a couple days ago, i noticed my phone slowing to VERY very much, huge lag and latency. i barley run any appas at work, ill check a couple of websites, facebook and txt messages. I checked spare parts > Battery History and Running is at 100%. when i check partial wake usage, no apps seem to be staying awake and draining my battery. any1 ever experience this? is there another way to see if there is an app/service bogging down my phone. sometimes i notice when im on 4G it also slows doen, but it has never drained my battery like this.
im considering wiping the cache and dalvik, would that help?
Yes wipe both and then go to "Other" and select 'Fix UID mismatch' while you're there.
Another app that can help narrow it down is "SystemPanel Lite", free on the market.
Or if you like, start using Juice Defender and maybe even buy the UltimateJuice for 3.99 if I remember correctly, It gives me a x1.87 boost, so It could work...GL
And I just found this useful bit of information on each method to save your battery or increase it in fact here it is the link http://home.comcast.net/~evobenchers/index.html viola enjoy
Thanks for the suggestions, ill see if it helps within the nest couple days
Good luck...nothing has worked for me. I have done all of the above and it still happens. 4g does seem to slow it up also. My phone runs around 100% but no apps are draining it. Very rarely will watchdog alert me on an app draining the usage. I do not want to do a hard reset but that is sprints only answwr.
Hey, are there any side effects to wiping the cache and dalvik without flashing a new rom? will i lose anything?
Edit1: also, i'm looking into WatchDog. which version are you using skillzo1?

None other than your first boot up will take a little longer as it rebuilds the Dalvik.
It probably could be considered a good maintenance step as is cleaning up "Other".
Ok, so check this out and tell me if you're experiencing the same:
After fresh reboot:
After a hours/days of usage:
Just took this one on Liquid 1.25 (4.0.4 based)
After reboot
You're looking at "System" RAM usage and its affect on total RAM usage at the top pie graph. Is this normal? It's very annoying because it runs considerably slower after a while, so I check the RAM usage and "System" is taking 4-5 times more RAM than it does after a fresh reboot. I wish I could just kill/restart the service without rebooting the phone. Or better yet; keep it from getting that high in the first place. It causes constant OG Droid-like launcher redraws almost EVERY time I hit the home button, taking at least 5-10 secs for the icons to even start appearing and probably 20+ secs for it to be fully loaded and scrolling to be smooth again (using Apex at the moment because Nova seemed to be worse than that). I wish we could see what the remaining ~300 MBs of RAM were being allocated to too.
As long as I have around 150MB+ free, the phone seems to run great. But that "System" seems to slowly creep up in RAM usage until I have 100MBs or less free, bringing things almost to a halt. I have noticed this across a couple 4.0.3 (shown pics I'm running Codename Android 1.5.0) ROMs and just saw it again for the first time on a 4.0.4-based ROM (Liquid 1.25). I was hoping the update would address this . Also, no amount of killing apps or disabling Google services brings this number back down. The only way I've found to fix it is to reboot, which I find unacceptable. I don't want to reboot my phone multiple times a day to keep it running fast.
TIA for any insight, suggestions or help.
FYI: The app I'm using to display that info is called "SystemPanel" (free and paid version in the Play Store).
Update: Here's a video I made to show what I've found that causes this. If you're running this ROM or have a ROM with a lockscreen like that (as I did with Codename 1.5.0), please see if you can replicate this. It seems that once I enable that octo lockscreen, the memory leak will be permanent after I enable that because I can revert it back to the stock lockscreen and it will still increase System memory usage after ever unlock.
Update 2: I've replicated this on AOKP now using the same lock screen setup. Now you can see me crashing the phone after only locking/unlocking the phone.

Have you compared this to the default tool under 'Settings > Apps > Running'? I've never used that tool before and am not sure where it's getting it's numbers from. But I do know that a high amount of RAM being used is not necessarily a bad thing, since it might just be cached. I would recommend using Elixer 2 for all the stats you'll never need for your phone. When I checked the "android system" process was taking about 100mb
Maybe you should try the stock ROM? I didn’t install the app you noted here, but I also don’t have this crazy 5, 10, 20 second issues that you have after a week of uptime.

Yeah, I've looked at the stock app manager and it showed about the same amount of remaining RAM when it was down to ~100MBs. But right now it's showing about 90MBs less RAM available on SystemPanel as compared to the stock app manager.
Thanks for the Elixer link. I've never heard of that and it seems pretty nice. On Elixer, the RAM usage amount it's displaying matches up exactly with the "Resident" Memory Usage displayed on System Panel (2nd and 4th pics in OP). I'm not sure what the difference between "Resident", "Effective" and "Shared" memory is, but it seems "Effective" is what's actually utilizing the physical RAM on the phone since that's what's being displayed on the main processes/services page in SystemPanel.

Yeah, I'm considering that because I ran my Nexus stock for a few weeks just to make sure my hardware was good (my first stock/unrooted Nexus randomly rebooted periodically in its first week so I exchanged it for my current one) before I started rooting/ROMing the phone and I don't remember ever experiencing anything like this on stock 4.0.2. I definitely didn't have many launcher redraws, if at all. It just sucks going back to stock after being used to all the extra functionality of these other ROMs. I really like having all the status bar customization/widgets, fast charge/LTE toggles and most of all the search and menu buttons on the Navbar.
It's annoying to have to compromise the speed of the device for more functionality. It seems no one else has these same issues, but I do and that's why I'm here trying to figure it out so I don't have to make these compromises if possible.
Thanks for the responses . Any more are very welcomed.
Wow this looks like a problem. I haven't noticed this issue but I'll start paying attention. I use system panel all the time. I can confirm however that my total ram amount never ever gets below 200mb, so I prob don't have this issue.
Bump for help.
first thing i would do is try stock. it's not hard to go back to your rom if you make a backup.
see if the problem resides in the rom itself.
I have the same EXACT problem on 4.0.3 AOKP... its really starting to get annoying i just used the app and found my system is at 300mb!

Use stock. It has been mentioned several times. If it doesn't have issues, then its crappy roms with memory leaks.
If it helps I'm on aokp 29 4.0.4 and haven't seen this bug yet. I keep checking periodically.

So far I don't have signal issues.
I think I may have somewhat figured this out now.
I went into my "Superuser" app to see what apps had root permissions and "system" was among them. So I toggled it to "deny" and rebooted the phone. Upon reboot I got a prompt that "System" was requesting root permissions. I denied that too and left the box unchecked so it will prompt me again if it tries to access root again (to see what actions trigger it later). So far "System" has stayed in the 50-60 MB range for usage, but it's only been a few hours since that reboot. I'll have to monitor it for the next day or so to see if that keeps it down.
I've noticed something since monitoring this "system" usage for the past week too. Once it reaches around the 300 MB spot in RAM usage, it causes my phone to reboot. I've seen it consistently do this 3 times in the past week or two. So there's definitely like a memory leak or something because it slowly but surely increases. Every time I went back to check it after a few mins of usage, it would have raised by at least 1-2 MBs. I don't think I've ever seen it lower in usage. It seems like the more I use my phone, the higher the RAM usage gets for "system".
So could anyone that's reading this thread (that's rooted) check their Superuser app and see if this "system" app is listed and what permissions it has? I'm hoping that I've found out that it's not supposed to have root access. But then that begs the question; what is "system" and why is it requesting root access? If it's a legit service; should it still have root access?
I'm hoping to see that no one else here has it listed in their Superuser app so that I can leave it as it. I just hope it's not something that requires root access and will interfere with the OS at some point if it don't have the permissions it requires.
Thanks for all the help so far!
System requiring root access?
I'd call that a malicious app.

Yeah, I was thinking that too, but could you please check your running services and Superuser app to see if you see it in there too? That's what I'm trying to see.
Thanks!
Only in system panel.
My apologies. I do under system panel. It looks like the screenshot in the original post. However, it definitely does not have root access.

Thanks . I wonder why a lot of other people see it running on their phone too then? I doubt we're all infected.. .

Good question. I'm on LiquidSmooth 1.25 at the moment though.
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.

hahahahah wtf
Phone is the 6GB RAM 64 GB storage version.
For the last couple of weeks it slowed down to a crawl when it comes to launching apps. For instance it takes 18 seconds!, I timed it, to open Skype on my phone. Other apps also open very slowly. Once they are opened and kept in memory they are re-opened instantaneously so the problem is only when launching the apps the first time.
There is about 2.8GB RAM available, only 35% of storage space is used so there is no reason why the phone should run so slowly.
I have upgraded to Oxygen 5.0.4 but no change.
If I run it in safe mode I can't check if it's slow or not because no user apps are available.
I have cleared Cache and Dalvik cache repeatedly to no avail.
Any ideas would be appreciated.
Does this also happen on newly installed apps? It could have something to do with the ART optimisations on app launch but you experience it every time you open it from scratch?
1. your phone is fake or defective
2. you have installed some battery saver apps
3. you have flashed some custom kernels
I have used OP5T for over a month and I have to say, it's the fastest phone ever I have till now, before OP5T I got S7E, NoteFE, Mate 9 and IMO Mate 9 is really fast with Kirin 960 but OP5T is better and smoother than Mate 9 in many aspects. The things I missed so much from Mate9 are Sdcard and extremely long battery, the rest are fine for me on OP5T.
SOLVED.
It was an application called ProtectMyPrivacy, PMP for short. If I don't start it after rebooting for some strange reason it slows the phone down incredibly. It's a very useful application, it blocks all the sleazy apps form accessing, unbeknownst to the user, things like Phone Unique ID, Contacts reading, Calendar reading, Fine Grained Location, Mac address, etc. It's crazy how bundled apps we aren't even aware run in the background collecting all sorts of information and sending them to who knows where. Apps like AdMob, Flurry, AppBrain, AppsFlyer, InmobiFabric, Hockey App, etc. that are part of a regular app that we download but we have no idea they are bundled in. Sleazebags.
Anyway, PMP blocks all these bastards from spying on the phone but I need to start PMP manually every time I reboot the phone. I sent an message to the developer, SynergyLabs at Cornegie University, to let them know about the issue.
