[Q] /cache - HTC Aria General

Quick question. Had my Aria for 4 months now. I noticed on my OS Monitor app it says system cache 50% full (40,960K total 20,454 used). What happens when it gets full? I guess with an unrooted phone I can only delete an applications cache?

Cache will be deleted automatically if it needs more space, etc. It's all automated. Nothing you need to mess with on your own.

"Nothing you need to mess with on your own"
No need to imply that i am feeble minded. I am a mechanic
by trade who performs diagnostics with engine control units and can swap an engine block in less than two hours, but I get nervous about rooting a little phone. I can't figure it out.

Whoa there, BeanTown...
No one is implying any feeble-mindedness on your or anyone's part.
Drumist is simply stating that the Android system handles this by design, and that it's not intended to be fussed with by users.
It would be like having a watch and manually advancing the minute every 60 seconds instead of letting the watch keep time on its own. Yes, it can be done, but no need to mess around with it.

Understood.

Clunky Like Windows 95? Hmmmm.....

First, I am straight vanilla on my EVO--stock ROM, no root, etc. But I have noticed a behavior pattern in Android that reminds me of Windows 95. I am not a heavy or light user, just standard. But I have noticed that after a month or so, the UI begins to get clunky or jerky or sporadic (put your own word here). But if I pull the battery for a complete restart, it runs as smooth as silk again for about another month, when I have to repeat the process.
This reminds me of the old days of Windows when even Microsoft recommended PC's and servers be periodically restarted to clean up memory issues.
You went a whole month without rebooting your phone??
I've noticed a little lag after a few days but I rarely go even that long without restarting for one reason or another. I always though periodically rebooting was just something that was good to do anyways.
That is pretty standard for smartphones. I restart mine every morning when I get out of bed.
the fact that you can go a full month without rebooting your smartphone says something I think.
Well, I haven't been tracking the interval on a calendar, but a month (plus or minus a week) seems about right. But I am astounded that this battery-pulling process is "common" knowledge or that anyone would would think that doing it every morning is an acceptable practice!! Seems that people that b*tch about wifi speeds and light leak would be putting a gun to their heads if they had to reboot every morning...LOL.
You are "stock" not "vanilla". The two are not interchangeable. Vanilla implies AOSP non-sense which is what you want if that ui is bogging you down. Try adw or launcher pro and that sense ui lag will be a thing of the past. A custom ROM like cm6, fresh, or baked snack will fix you right up.
Swyped on my EVO
I am pretty sure none of the people who answered pull the battery for a restart. It's as simple as getting a program (quickboot) from the market to do it or long press on the power button. That is not a hassle at all, and really, every smartphone should be rebboted from time to time. This phones are now mini computers and as such from time to time will need rebooting to keep things smooth.
+1, pulling the battery is not necessary to reboot. I don't know why Sprint would suggest that is any different than just rebooting..
whats the name of the App in the market that will reboot your phone for you at a specified time/date/interval?
I know its in the market (and requires root) but i cant remember the name

I saw the thread about someone asking if an app like that exists, I didn't think it had been made yet.
I can see how someone who is not rooted could go a month with out restarting there phone. I mean most of my restarts happen because i am flashing a new kernel or rom or some combination of the 2.
What others listed is true though almost all smart phones need a reboot from time to time. Even newer PCS with win 7 you should reboot now and then so this wasn't only windows 95.
Also as stated above you dont need to pull the battery just power down and power back on and you should be good to go.
I think having to reboot your phone is a ridiculous notion. Just because it has the functionality of a mini computer doesnt mean that shortcomings of computers should be forgiven...
I mean, hell, portable gaming systems are getting more and more popular, but no one says hey its okay for my ds to overheat because its becoming more like an xbox 360...

good one
a power cycle is unavoidable, thats when your system cleans up and wipes whatever isnt needed like temp files and what not, even regular cellphones from time to time require a restart, all computers require restart, what im more interested in is how android handles memory fragmentation, in ubuntu, they recently released a kernal upgrade that allowed for ubuntu to handle huge file sizes but now requires defrag to be able to compensate for fragmentation caused by using such large files and i was told that android has some sort of 2gig limitation on the overall os and i believe apps have a 15mb write limit or something of that sort, would that be to try and avoid memory fragmentation??

That's not a fair comparison at all. Overheating is something that can damage an electronic device. I've never heard of a phone getting damaged by rebooting it.
Hell, for all we know, the OP doesn't even need to reboot. Running a task kill might have been enough to fix his problems.
IDK about you guys, but my battery dies so often and quickly, I don't think I can go more than a day without it dying at least one...
Whats the big issue with restarting? Takes like 1 minute.

EXT4, journaling, data integrity, reboot, space aliens, and robots

Well, okay, nothing really about space aliens and robots, but you're here reading, aren't you?
Lots of discussion about pro/con of the EXT4 filesystem, risks to data integrity without journaling (analogous to a transaction log for a database), the disappearance of the reboot option on Bonsai (and maybe other ROMs) because of this, blah blah blah this, blah blah that, and on and on and on.
There is another solution. You can still have the performance of EXT4, without journaling. With much lower risk to your data in case of the battery leaping out of the phone on a whim. And good ol' reboot can make a comeback too!
The nirvana is a linux command called 'sync'. Crusty old unix hacks like me will get a twinkle in their eye at the mention of this command.
sync does somesthing very straightforward and simple: It syncs the filesystems. Put another way, it flushes the in-ram buffers out to "disk", syncronizing the actual state of the filesytem with what is stored -- and stale -- in secondary storage (hard discs on the big boys, NVRAM/SD/whatever on phones).
I've been experimenting with this to see if I can improve data integrity while minimally impacting performance. Here's what I've done:
Using GScript Lite, created a simple Superuser script for rebooting that looks like,
sync
sync
sync
/sbin/reboot #Bonsai ROM
Why 3 syncs? Paranoid. Nothing more.
Optionally create a shortcut on the homescreen to invoke this script to easy one-button reboot. I did this a week ago, have been using this to reboot Bonsai 4.0.0 a gazillion (actually, a bazillion, but I'm rounding) times, and have had absolutely no problems at all. Seems to work.
Created a shell script that launches at boot, as superuser, that runs in an infinite loop waking up every 10 seconds to do a sync. No detectable impact on performance that I can see. This is what I'd expect, as there is never more than 10 seconds of filesystem activity sitting "dirty" in the cache, so the sync doesn't usually have much to do (most of the time, nothing).
What does all this mean? Well, it's sort of a "lazy" journaling, and much more efficient. There's still a higher risk of data corruption under uncontrolled loss of power than with journaling, but in my considered opinion its negligible with the usage model/patterns for this particular situation (a smartphone).
FWIW, before I implemented this method for reboot, I like others got FCs on apps randomly after using the 3-finger reboot, simply running reboot directly from a shell prompt, or back on Bonsai 3, using the power-button menu reboot command. With this sync approach, I have not had a single problem -- and I can reboot the phone again easily!
What this means for you
If you're enough of a hack to understand how to implement this stuff yourself, give it a shot (at your own risk!), and let us know how it works out.
For the rest of you, be patient... I'm putting together a package to make it simple to install all this (initially just for the Bonsai ROM, others to follow, maybe), and should have something to test in a day or two. If you're interested in being a tester, PM me. Looking for 10 people.
I'm interested in this as I have been wondering about no_journaling for some time. I think it would help to prove or disprove the theory that no_journaling is causing data corruption. PM sent.
This is very interesting. I'll be watching this - depending on the results, it may be a good option for future versions of SRF.
I think a mod should move this thread over into the Development forum, please?
This sounds interesting. So will this "lazy" journaling put the same or less wear on the nand chip vs journaling being enabled?
If it has the same or similar wear factor as no journaling, as well as no impact on performance. Then this mod is a no brainer IMO.
Does sync only cause a write operation for data that has changed, or simply rewrite the entire buffer to disk each time? I'm sure you can see where I'm going with this...

It's better than nothing, but it still doesn't address battery pulls or phone freezes. It just provides a more graceful shutdown IF you do a clean shutdown.

I tried this on my phone and so far, so good. I am using ACS Frozen Rom 1.1.0 with Twilight 1.1.0. When I downloaded the GScript lite, there was already a script for reboot, I just edited it to add the sync lines. I assume that the #Bonsai ROM is a comment and not needed, so that was omitted. I have rebooted about 10 times (I know...many, many less than a Gazillion) and have not had any issues.
Thank you!

In terms of the precise impact on storage, it is indistinguishable from not doing it at all. All this does if change the timing of the writes -- you control it, rather than waiting for the OS to decide to flush the filesystem buffers.
In the case of a reboot, this makes a ginormous difference, because anything in cache that hasn't been flushed is lost if the system doesn't sync before quitting back into the bootloader.

only dirty blocks.
sync should not cause anything to be written that wouldn't be eventually written anyway, when the kernel decides it is either idle enough to perform the deferred task, or cache "fullness" requires it to make room for newer data by flushing older stuff that hadn't been written yet.

True on the reboot mod.
On the monitor, though, it can make a big difference in the case of catastrophe. The FS cache is never more than 10 seconds out of sync with the underlying NV secondary storage. Depending on the usage model, this may be enough to reduce risk significantly.
The interval, of course, is configurable. The monitor could sync every second, reducing risk further. Given the speed of the processor in the 4G, and the low overhead hitting sync when there's nothing to flush, the overhead at a one sec interval may be trivial.
I haven't progressed far enough with this nascent idea to have characterized such questions. It's on the work order, though.
Also, my rough experimentation with this is all via shell scripting, which has a lot of unnecessary overhead. Coding this into an Android service, calling the linux sync(2) system call directly will be much more efficient.

Yes, just a comment... across different ROMs I've found that devs mess around with the location, and linking, of the reboot command.

[Q] Nexus 4 malware attack? Help please!!

Hi All,
This is my first post on XDA and I hope that I'm posting in the right place!
I have a Nexus 4, 4.4.2 which has never been rooted. For what it's worth, I've always run AV software (Lookout from day 1, subsequently Kaspersky) and only downloaded from the Play Store. (I have always had 'Unknown Sources' unticked). I'm pretty careful with permissions.
In hindsight (a wonderful thing) things started shortly after one of the Kitkat OTA updates. Not absolutely sure which…
One evening, my lock screen clock suddenly showed my time as 3 hours ahead (i.e. Moscow: I'm in the UK) along with a rectangle giving my home time zone time. I googled the symptoms and it seemed widely reported so I just put it down to an update bug and carried on.
However, I've recently been having large, unexplained, data spikes in seemingly innocuous programs. Specifically, I had a 6GB spike attributed to Opensignal. I uninstalled Opensignal, but the data use continued, albeit on a smaller scale, reported in Data Usage as 'Removed Apps'. This was definitely data use *after* the program was removed: I altered the sliders to focus on the time after uninstall.
To be on the safe side, I gritted my teeth and performed a factory reset and altered my important passwords.
However, this is happening again.
'Removed App' data use has started increasing once more and have just had another large data spike attributed to, of all things, Kaspersky. Over 600MB in a day. All data is now turned off, but possibly too late?
Do I have to assume that the phone is well and truly hacked? If so, am I going to have to unlock and root the phone and side load a factory image from Google, or is there an easier route?
Many thanks in advance for any help.
Cheers,
Edward.

I know you probably isn't going to like this, but for the most part, apps like Kaspersky and lookout does a lot of phoning home, thus use a lot of data. Some will say they are useless, but that's a judgment call. I have tried them but usually end up getting rid of them.
I don't know OpenSignal so I can't really speak on it. What's it used for?

no silly Malware are for Windows. You said Kaspersky? lol.... anyway seems like an app issue. I always enable > set mobile data limit to certain MB / GB. Try checking other apps aswell like (Google Plus, Facebook) disable auto photo sync.
To Factory Reset:
1. Backup your files from your sd card.
2. Download Nexus 4 4.4.2 (KOT49H) image from here.
3. Extract it using Winrar or 7zip.
4. Connect the Nexus 4 to your computer and run *Flash-all.bat*
5. Let it do its magic.

Hi,
Thanks for the reply.
Opensignal is a crowd-sourced mobile/wifi signal mapping app.
Can't post a link yet (only 1 post!) but if you Google it... Had it installed for ages and didn't use more than a few kB a day, as one would expect.
Really think it's something deeper than this, because programs are continuing to use data after uninstall and, although AV programs use a fair bit of data, half a gig for just definition updates seems silly.
Cheers.

My suggestion would be to wipe your dalvik, cache and at the extreme your data, but you're not rooted.
The AV app(s) does a lot more than check for definition updates. They also check out the websites that you visit as well. That could account for the data used.
I'm not aware of an app that could wipe the mentioned partitions without root. Maybe someone else might know?

Precautions to erase all personnal info from a device

Hi all, I am starting this thread for my own info, but also hopefuly to see if it can be helpful to others in the future.
I often change devices, and soon will resell my S4.
Usually, before doing so, I wipe all, including internal storage from recovery then flash a stock/stock looking rom.
Should that be enough to get rid of absolutly everything? I recently heard a podcast where they were discussing the fact that many phones sold on ebay and such still contain quite a lot of personnal data, but I tend to think that the people reselling their devices just don't even take the necessary precaution to wipe it.
They went on saying that encrypting the device, then removing the encryption would make sure that nothing is left, but is it really necessary in your opinion? I am thinking that simple formatting all as I do (and many of us too I guess) should be enough?
What do you think?

When you wipe your data you are still able to recover them with programs like Recuva.
To be 100% sure you have to delete your data and overwrite the complete internal storage with senseless information.

Oh yeah I see, but it is still some "work" to get information from an individual person, what I mean I do not hold any sensitive info or anything.
But good to keep in mind, i guess I'm just wondering if that would be enough for normal usage... No personal info can normaly survive such a wipe I think
When you delete data on a storage it still stays there. It isn't deleted, the system just releases the space for overwriting with new information.

For normal usage, yes. Using Odin to flash the stock ROM will remove all references to your data. The data will still be there but will not have a file structure so a normal person getting their hands on it won't know that there is existing data and will overwrite it with their own data in due time.
If you sell it to someone who knows what they are doing, the data is easily accessible.
If you really want to kill the data, kill the phone. Put it in the microwave for 45 minutes. Have a fire extinguisher handy. The phone will not have any data remaining.
(Do not actually do this. You will burn your house down.)

If you want to be more thorough figure out how much free space is on the internal storage and then upload that amount of mp3's to the storage. Then delete them. That will overwrite your data.
It could still be recovered by someone who REALLY knows what they are doing, but at this point you would have to be paranoid to worry about it.
On a tablet forum I frequent I had this exact question asked, and the solution I gave was to encrypt the data first, then wipe the device. That way if something is extracted from the device, it's virtually useless as the new owner won't have the necessary information to decrypt the data.
Yeah, all those would work too
I'm not that paranoid, as I don't really hold any very important info on this device, I think i'll just go for a complete wipe, thanks for your input guys.
There is a software named NUKE MY DEVICE.. its an apk file.. install and run it on ur device..it will erase all the data and the data will no longer be recoverable..

Hight CPU and battery usage on idle system; restarts don't help

I've got a problem with my S8 which is running latest, official, non-rooted XEO firmware. Specifically, it uses battery like crazy and heats up whilst doing nothing. This smells like a virus / malware infection or just... well, the last update was in December 2021 so it's also possible some system component is wonky OR... <shivers> some rootkit? I'm generally rather careful when installing apps, most of which will be coming in from official sources (Google Store) or at least fairly trusted sources.
Every so often I'll get a warning that a system component is using too much CPU and I should restart the phone - which obviously doesn't help at all. Also the battery drain is reported primarily by Android System and System Core (29 and 15% respectively). Battery usage stats generally don't add up because the listings don't add up to 100%. :/
I know the S8 is an old phone... and I know there are probably steps I should take prior to asking here - like a factory reset. But I'm really sceptical of doing a factory reset simply because I've got so much stuff on the phone that, while not impossible to backup, is certainly annoying (authenticator or banking apps for example - and I don't think the standard backup tools like those available from Google or Samsung backup such apps).
So I'd rather try some solutions or methods of dealing with the damned thing without resetting the phone first. Is there anything I can do?
You need to find the root cause. It may be a 3rd party using one or more of the Samsung system apps running under Android services, lol Legend for there are many... all lumped together.
A firewall with logging can help. Karma Firewall is what I use, uses almost no battery. Being rooted you have more options... use them.
Malware is always a possibility.
3rd party apps can cause hell. I don't allow any social media apps on the phone, ever.
Try in safe mode... if things calm down it's likely a 3rd party app. If so start going through the installed apps.
Clear system cache.

Sorry about the root thing, my bad.
If you're running on Android 9 or lower Karma Firewall's logging feature is fully active otherwise not. Samsung store>Galaxy Labs> Battery Tracker can be useful.
I use Accubattery's history page to get a quick idea of charge/discharge rates.
I use Device Care>storage>clean as well.
Make sure no cloud apps are running in the background.
Update: in safe mode the phone doesn't heat up and battery usage seems normal. So it's probably some app.
Alas, the firewall wasn't very helpful - it seemed that apps that attempted accessing the internet were your usual suspects - Play Store, One Drive or other sync apps, Vanced.
Any other suggestions on possibly nailing down the culprit?
PS. I've also decided to send Samsung an error report via the Members app - I don't know what their reply times are and I honestly don't expect much from them but who knows? Perhaps they'll come through.

Why other than maybe text messages is anything syncing? Take out the trash and go from there.
The ones that are connecting every minute or more when not open are prime suspects.
Some apps like Brave browser need to be closed out when not in use or they eat battery.
You can also try a hard reboot.
Update!
I left the phone in safe mode overnight. I mean, it seemed like things were better, so at least I'd have a stable phone.
Well, in the morning I was greeted with a severely depleted battery (went from 100 to 40 in the span of 6 hours) and I got the "high CPU usage" warning popup. The phone wasn't as hot to the touch tho.
So... Whatever is going on seems to happen also in safe mode, albeit less often? Or perhaps it's less "severe" where it doesn't heat up the phone but the drain is still there? But since safe mode is affected it's probably NOT an app, right?
At this point I'm completely baffled. Any other ideas?

Update!
I left the phone in safe mode overnight. I mean, it seemed like things were better, so at least I'd have a stable phone.
Well, in the morning I was greeted with a severely depleted battery (went from 100 to 40 in the span of 6 hours) and I got the "high CPU usage" warning popup. The phone wasn't as hot to the touch tho.

Hard reset... hold power button until it powers off.
Try temporarily disabling Google play Services at night, see what that does.
OK, I'm baffled. I feel like I didn't really do anything but the phone is now running fine. Battery drain now might be better than ever!
Warms up on usage, obviously, but when idle it's nice and cool and battery drain seems minimal. I'll... leave it for a few days to see how this develops. It's very difficult to tell what the heck's the case here.

Retrace what you did. Reason being you may need to do it again. Really most times all you need to do is just "play" with it a bit (a lot). Almost impossible to crash a stock load, so explore and learn by playing with it. You are what you load and download; be careful with 3rd party apps they are the biggest potential hazards.
Once you have a fast, stable OS that's fulfilling its mission, let it be. Don't update or upgrade it.
Updates can and do break Sammy's. This N10+ is still running on Pie, current load is over 2yo. Rock solid stable and it runs like a bat out of hell with minimal maintenance. Security isn't an issue.

I have a suspicion this might have been some Samsung app (my bet's on Bixby) since those are likely still able to run in Safe Mode that got updated and then fixed...? Does that make sense?

I'm concerned about the last bit. I mean, upgrading to a new Android version is one thing but security updates are common, no?

Kill wittle bixby... you read it EULA?☠
It's more than one apk though. Takes a while to optimize a Sammy the first time
Well... if it's set up and used right Android 9 will run securely in the real world. No saving dumb bunnies anyway; they'll still get tagged even with the latest version
The proof is in my hand. Loaded over 2+ years ago and this N10+ UI version 1.5 is running clean like a bat out of hell. If I do get malware I can't erraticate in an hour or so, factory reset and change passwords.
My data is redundantly backed* up 4+ times, plus the onboard SD card used as a data drive. I'm ready to reload right now if I have to...
A malware forced reload is still less trouble than constantly updating and having the updates screw things up. That means more troubleshooting, finding new work arounds and still maybe needing a factory reset on top of all that. No.
Not vaxed either... not buying the hype.
*critical data must be redundantly backed up or sooner or latter it will likely be lost. Never encrypt data drives as you are the most likely to be locked out!

Oh I'd love that - but it's a system app and removing those without root is kind of... impossible? I can look into disabling it completely however - I never use it anyway. Since it's not a single app - any chance you got a link to the list of apps that need manual disabling?
Anyway, I'm still getting those damned warnings. The phone isn't constantly hot however, which is some improvement.

Package Disabler kills bixby proper.
You can also disable it with an adb edit. That's one of the first things I do.
Bixby is a hot mess best dump along the interstate... like Google Assistant it needs external servers for many of its functions. I may change my mind but it's eula is like eating dry hardtack for breakfast.
