[Q] Performance Decreasing: After first reboot and over time

I have flashed many Roms over the last year, Jedi Roms, Infamous Roms, Stock, and most recently Rushing's Shadow Rom. I have stuck to only Touchwiz based Roms since I need WiFi Calling to use my cell phone in my apartment.
The one thing I noticed every time I flashed is that the phone would get significantly slower after I rebooted the phone the first time after I installed a bunch of apps. (Not after the first one I do after the phone has resynch'ed contacts and stuff from google) Additionally, after a couple months the phone would get so slow that I would reflash a new Rom (generally, by this time a new version, but if a new version is not available, I usually switch Roms)
The apps I usually download include:
Google - YouTube, Maps
T-Mobile -Visual Voicemail
Media - Pulse, BeyondPod, a music player
Root stuff - Titanium, Rom toolbox, ES file explorer, etc.
Popular apps - Facebook, twitter, ebay, bank of america, etc.
Are any of these apps known to degrade the performance of your phone over time? Is there a way to diagnose which of these apps are running and when?
A second theory I have is that something on my SD card is either corrupt or not getting wiped properly. Then, these corrupt sectors/files cause performance to decrease over time? Has anybody heard of anything like this? Are there any utilities out there to look for corrupt file. Can anyone reccomend a SD cleaning app that might help if this is the case?
A third theory is that these customized Roms aren't as stable as they are thought to be. I don't believe this is the case since the developers on this forum are much smarter than me, and thoroughly test their roms. Additionally, I have seen this happen with Stock rooted also, which also discounts this theory.
Most of this is spit-balling so that people can see my symptoms (if you had similar symptoms, please share troubleshooting steps and resolution) as well as maybe trigger an idea in someone that has an easy fix to my issue. I like this phone a lot and I don't want to buy a new phone just to avoid these issues. I think this phone is still capable of handling the workload of a 2013 smartphone.
Please let me know any tests/logs that would help you help me solve this problem.

Want to give my S3 to my mom - what's the best setup for a smartphone newby?

I haven't used my S3 in a while since I got my Nexus 5 but never got around to selling it. I was thinking of giving it to my mom instead, who's never used a smartphone but expressed some interest in getting one.
I had unrooted and flashed a stock Rogers 4.3 in anticipation of selling it.
Last week my Nexus 5 died and while waiting for my replacement I was using the S3 again as a backup. Since I only needed it for a few days I didn't do any rooting or customization and lived with the stock experience.
However, I found there was serious battery drain. Much more than I recall when I was using it prior to 4.3 (which came out around the time I switched phones). Based on betterbatterystats it looked like this was being caused by a wakelock related to google network services. I see the same wakelock on my Nexus 5 but it doesn't seem to cause any drain while sleeping while on the S3 it's probably losing 20% per hour while sleeping which is a major issue. Is this a known issue with Samsung's 4.3?
So I want to give her the phone in a state that is as maintenance free as possible. I planned to just keep it stock but the battery drain is going to make this phone useless for her and any kind of apps/utilities to tweak battery usage is not going to be a tenable solution with the phone in her hands. She's going to have her hands full just learning the basics.
Is there any way to fix the stock ROM to fix this battery drain issue? If not, is there a custom ROM that does not exhibit this problem but is fully stable and usable by a non-technical user? My experience with custom ROMS has been they all seemed to have various bugs or issues, probably related to incomplete driver support. That's one of the reasons I wanted to get a Nexus. But I haven't followed S3 development since so any suggestions on stable ROMS that don't need any tweaking would be appreciated.
Thanks!

On the stock side, you could start with a non root debloating effort.
Two basic principles are:
Eliminating 2x & 3x built in apps & services like email client, music store, contacts sync, social networking updater, weather widget etc. That is to say pick from the Samsung, Google or AT&T (or no) version and "Turn Off" the others in Application Manager, as able. Obviously root & say, App Quarantine would give greater reach there.
Secondly, reducing unneeded background activities like synching in selected apps' (like Gmail or Skype) settings menu and, if sufficient wifi uptime is available, "Restricting background data" per app; below the pie chart (in Settings/Data usage, after scrolling downward from the bar chart to click on individual apps.) This will limit top background data hogs from overusing cellular data connection activity (with its battery impact) & restrict them to the wifi connection. This works (non destructively wherever real time data can wait for wifi).
My rooted, modded stock 4.3 may be a little less restrictive than yours, but these procedures can make a pure stock flash tamer while considering root options.

Korean Galaxy Note 2/Note 2 LTE keeps restarting

Hello everybody,
got this mobile a few months ago, latest Android officially available release, only thing I did was rooting and adding some software, I use it as a second device mostly to check email and online services, I use my other smartphone as a phone and for calendars, phonebook and notes.
I noticed that the device all of a sudden restarts without me doing anything, my son (who uses Android since longer than me but who doesn't really know much about it...) said it could be the heat (it's always in the shade) or too many options on (wi-fi in primis) but I checked and there are just a few apps running (mail, phone, phonebook, sometimes Instagram), what can I check to find how does it restart without any notice or action from me?
Thank you

soory

I had an issue where my Note 2 would randomly reboot, I also had an issue where my power button was dodgy.
What it ended up being was the ribbon for the power button, got this replaced, and this fixed my dodgy power button issue, as well as the random reboots.
I paid to get this done in a shop, but it seems you can do this yourself.
Sorry i can't post links - hope this makes sense

Of course, your problem might be different

Dear Giuann
What you are experiencing is know as SOD (silence of death) on our Android World
If your phone is rooted and you have custom Kernel then it would be due to the kernel... change your kernel to stock or a more stable one as per your device.
If you have a stock kernel... then clean your cache.. etc.. or better reflash stock ROM...
alternately use Betterbattary stats to identify if you have any rogue application which is causing issues...
I have experience this issue when I did rooting.. re root it with the correct method....

I did only root it as to install software I download from the internet, everything is as it originally was, ROM is the stock one.
Which are the steps to perform to clean the cache and to check if some app is making the OS crash?
Thank you

Updated Google Play Services killing my phone(s)

I'm running stock AT&T 4.0.4 ROM, rooted with CWM. Google Play Services just updated to version 9.2.56 (034-124593566), and it's sucking my battery dry and making the phone run hot. I have a spare phone and brought it online, and the same thing happened as soon as Google Play Services updated. It is running anywhere from 50% to 80% of my battery when the screen is below 10%. Yep, it's using more than 10x what the screen requires. Battery that used to last 18 hours now lasts 2 to 3. Others have posted similar comments in the Play Store (like that's going to do any good). Common theme is it's older OSes.
I have tried disabling everything and it doesn't do any good. Too many things break if Google Play Services is removed. Going back to an old version is futile -- it self-updates within minutes. I tried GServiceFix and it works for few minutes, then the usage creeps up again.
I sent Google an email, but I expect nothing less than the run-around. So, I turn to XDA Developers.
First, is anyone else here still running stock, and did the same thing happen to you? How about on other ROMs (please specify)? Did you find a fix?
Assuming Google will do little to help, I need to do something to make my phone work right. So if there is a ROM where this is not a problem, I guess it's time to jump in. Problem is, some of the links in this forum are broken. I've found (or already had) most of what I think I need except a version or EFS Professional that works on our phone. I can find no working links to an older version that will do the job. I do have a Nandroid backup (also stored on my NAS), which I believe can restore the EFS, but I'd like to get just the EFS in case I need to load it to the system after flashing. None of the tools available in the Play Store seem to work on the Glide -- I end up with an empty backup directory.
My plan, assuming there is a Jellybean ROM without this issue, is to flash twrp-2.8.4-flashable.zip, since I understand TWRP is required for JB, then do another Nandroid backup with it, then flash whichever ROM is suggested to get over this. I've looked at Bubor's CM10.2, and it looks like it will fill my needs unless it also suffers this problem. If there is a reason I should update the Kernel, please let me know. I have not seen anything that makes me believe I need to.
Man, I wish one of the manufacturers would come out with a similarly sized new phone with a slide-out keyboard and AT&T compatible. I'd gladly upgrade, but there is nothing out there that meets my needs. Samsung S5 mini with slider -- I'm in.

Hi,
its one year later...
I'm with the same problem. Do you still have a solution?
Other ROMs have issues with camera and BT...

How to disable CNEService or its high usage of data?

Recently it is using a ridiculous amount of data (started a few days ago). I checked the data usage and found the name: com.quicinc.cne.CNEService.CNEServiceApp. How do I disable it?

I don't think it's a service you can actually disable. It's part of the chipset and is used to determine whether a WiFi or data connection is stronger in real time and keep you on the stronger connection. My understanding is that all of your data goes through that service regardless of which app is actually using the data so thinking it's that service itself that's using all your data is backwards. That number is basically a catch all for the data used on your phone by other various apps and services.

Is there any way to figure out what app or service is it?

Using Stock ROM? I had this some time ago. It's because it's downloading an OTA update in the background, failing to install because of custom recovery/root/something else, and retrying forever.
Some have suggested disabling automatic updates in dev settings, but for me it didn't fix it.
Flash the latest images and you'll be fine.

Thanks. I did root the phone. I just turned off the automatic update, hope it'll work.

Like mentioned by josdehaes, having automatic updates turned off still allowed the usage on my rooted Verizon phone. I saw one person suggest the issue might be specific to rooted Verizon phones, but I have no idea if that's accurate or not. Since my phone is rooted with SuperSU, and because I don't have anything else like TWRP installed, I just started using FlashFire to update. Keeping the phone updated to the latest software has worked so far, and letting FlashFire install the OTA on the phone is a lot quicker than messing with factory images or sideloading the full OTA. If that wouldn't have worked, I thought about installing a ROM that doesn't use the OTA, since the only other procedure I've ran across for stopping stock updates kept my phone from going into deep sleep.

High CNEService can probably be caused by a hundred things other than a failed OTA update and if it actually was an OTA update you should see an Android notification mentioning the fact that there's an update. Having a rooted phone on stock does not stop OTA updates from downloading successfully and it certainly doesn't prevent the Android notification telling you that an update downloaded or is available for your phone. If you bother to do a Google search on your "problem' you will find that people complain about the same exact thing on an assortment of Android devices regardless of manufacturer and most of the people doing the complaining do not have rooted phones. It has nothing to do with Verizon and most probably nothing to do with what the earlier poster suggested.

Having a Pixel rooted with SuperSU certainly can stop an OTA update. Although my phone had been updating fine using the OTA before installing SuperSU, either SuperSU or the changes I made with root would no longer allow the OTA, even after SuperSU was removed.

All the discussions I've read in the Pixel and Pixel XL forums that mention unexplainable and abnormally high cellular data usage, which the phone lists as being from a CNEService process, have been rooted phones that are not running the current update. As previously noted, it's the most likely guess, since that's the consensus from multiple threads. All I know for absolute certainty is that the Automatic system updates setting had been turned off, and my phone stopped the excessive data usage after updating to the current version. I had never seen any listings of which phones in the discussions were Verizon phones, so I'm not sure where the presumption came from that only Verizon phones might have been affected when automatic updates were turned off.

Pixels redownloading the OTA's over and over while failing silently has been reported many times here. No idea why, but they are always modded or rooted phones and usually​ a VZ phone or a Google phone with a VZ SIM

I'm not saying that having a rooted phone on stock wouldn't stop an OTA from updating successfully --on any other phone besides a Pixel that would pretty much guarantee that an OTA would fail to install. What I'm saying is that the OTA would still download and you would still see an Android notifications informing you that either an update was available for your phone or that one was downloaded and ready to install. Even if you are rooted on stock or are using a stock based Rom it wouldn't normally interfere with either the download or the notification --only the ultimate installation of the OTA. The fact that turning off Automatic Updates lowered your reported CNEService usage also doesn't prove that the problem was actually a failed OTA update --it could be that turning off Automatic Updates stopped a background process that was misbehaving or corrupted on your phone. Reporting of high CNEService usage isn't any more common on rooted phones than unrooted ones and if it is actually a sign of a problem and not simply a misinterpretation of what the number means then a factory reset pretty much always fixes it.
People have also frequently reported that turning off both WiFi assistant and the scan for open networks options fixed the same problem on their phones, even though logically you would think that would do the opposite and make the problem worse. But Android likes to simplify things for users by grouping the numbers for multiple processes under the same header, which is apparently the case for that number which is why it can actually indicate different problems on different phones, providing that there actually is a problem in the first place. People sometimes see that number and freak out assuming that it represents separate data used completely apart from their other apps and services but that isn't the case.

I should have mentioned that turning off both WiFi Helper and the automatically connect to open networks setting solution to high CNEService data usage actually came from the official Pixel Support thread on Google. People on XDA probably assume the issue is related to root because people on XDA like to root--to a hammer everything looks like a nail. But the same issue is also common on phones running full stock.

Far as I can tell, the original poster indicated that they had a rooted phone and allowed automatic updates. Prior discussions appear to suggest that could correlate with these high data usage events. I'd still take the position that turning off the automatic update setting on a rooted phone is probably a decent suggestion. Based on my own experience, I hesitate to suggest that turning off automatic updates eliminates the possibility of high data usage happening on future updates.

Actually, that is not a fact in relation to my comments. I personally had Automatic Updates turned off before the update notification.

Mainly I just take this sort of statement as merely a suggestion to consider other possible avenues in troubleshooting the situation, since I'm not sure what data someone might use that would be a necessarily superior choice. I probably did factory reset my phone after the high usage, so I suppose that might be an alternate explanation for it only happening one time.

I thought Wi-Fi scanning was always turned off on my phone, but one time when I was out of town I noticed it was actually on, so it's possible Wi-Fi scanning could have been on when I had my own high data usage event while ignoring the software update message. I think the Wi-Fi Assistant setting was most likely turned off.
People sometimes see that number and freak out assuming that it represents separate data used completely apart from their other apps and services but that isn't the case.

Again, I take this comment as merely a suggestion of alternate possibilities. The only thing out of the ordinary on my phone at the time was Google Earth, but it didn't seem to correlate with the usage, since the timeline didn't appear to match up and short-term use over Wi-Fi usually only reports as a few MB. I suppose with how Android automatically updates apps, maybe there was something on my phone at the time that was unusually using data that has since been corrected, yet I still don't see a clear reason to entirely discount the possibility that the event might have related with the software update being ignored.

Did anybody actually found a solution to this problem, or is it simply unsolvable?

Just turned off mobile data or wifi and CNE is turned off,
If you want to remove this service just goto /vendor/app/cne.apk
...
CNE - Connectivity Engine is the brain of the modem driver or Qualcomm chipset driver.
...
Removing this service makes your device save a lots of power best for you.
...
Removing this service can soft brick your device or simply your device can't connect to the internet.
