[Q] About the encryption, performance and future updates.

Hi All,
Finally got my hands on a new nexus 6 for a bargain price. I've been reading and searching alot in this subforum in order to answer alot of questions i had.
My 6 is upgraded to last ota available with the last security patches, but the phone is encrypted.
Now the question is, is either me that is over-sensible to slowdowns and juddering due to encryption, or the people doens't really notice it that much? It bugs me out.
Granted my 6 is not rooted and unfortunately due to the need of having a working phone in an hour i didn't even explored the possibility of disabling force encrypt, but afaik this would lead me to:
- Do a full wipe to keep encryption off and thus loose all my stuff
- Reinstall everything from scratch
Is that right?
Also if i got right, doing so leads to:
- Impossibility to install OTAS because doing so will re-encrypt my phone and i will need to start from scratch again
- Impossibility to upgrade to Nougat when released, granted it will be encrypted from the start
Is that right?
Also if those saying that encryption performance is almost the same of having none, why i'm having such lags, juddering, pauses between apps, low battery performance and excessive warm when used for long?
Is my phone faulty/my android version or that is what happens when you run an encrypted phone with alot of apps (more than 50 due to work)?
Thanks for those who will take a minute to answer my questions.
Have a good day y'all.

Thank you, actually i have all the stuff to disable the encryption. My point in question is, restoring a backup made in TWRP makes it encrypted again?
Because i want to avoid to reinstall everything, set my apps back from zero and so on.
Also that doesn't quite answer to the question about security patches and OTA's. Do the phone reencrypts itselfs and gets wiped if i force install an OTA or security patch?
Each time i need to do the whole process from scratch?

To change kernel, system and data partitions you need root access. When rooted OTA update will fail.
That's why many N6 users have a custom rom and Twrp-recovery installed.
To avoid hassle and reinstall data and apps.
I am using this rom: http://forum.xda-developers.com/showthread.php?p=59561445/
The dev updates the rom mostly before the official OTA .
About encryption: in daily use not noticeable.
Only backup is faster; twice.
Battery. The amoled display is consuming a lot of battery power. To avoid this I am using apps withdark themes and a black background.
So no Gmail but Aquamail.

Thank you for your insight. So i'm better off to a custom rom, updated with encryption off and call it a day?
I don't want to stick to CM or other roms, i would like to stick to official-based ones, to keep the sake of google pureness.
Thanks again.

In a short time the new version Android Nougat will be available for the N6.
I think it's useful to wait. Don't make changes before you updated to Nougat.

Yeah thats my point, the problem is that i can't bear anymore the sluggish performance and the lag, sometimes it slows down to crawl, and based on some benches i did its because the disk access is so high that even alot of cpu power is used. The phone becomes hot when managing 6 mailboxes, 4 social profiles and pages and tons of other activites.
It destroys my battery life and also the performance takes a huge hit.
I guess ill be patient and wait for Nougat to come in a form of custom rom.

Decrypt will not give you a noticeable Bett. performance.
Try the app Advanced Task Manager. To kill background activities.

Well then definitely something is wrong with my phone. It really (sometimes) slows down to something unbearable. I think i'll wait, if things gets complicated, i will do a wipe.
I never experienced such low performance not even on dual core phones. I had to reboot at least once yesterday to get things decent enough.

When a reboot solves the performance issue than try the app Quit Reboot (PhongIT). It has several options for rebooting. .
Another performance issue can be caused by the Google Play Services (searches continuously for updates), or apps working in background. Check the battery use in Settings - Apps - <app name>.
Disable the Google Plays Services temporarely to see possible differences.
When the battery is becoming warm/hot. Could be a bad radio connection. Switch to 2G.
Switch off wifi and bluetooth when you don't need it.
Delete apps you hardly use or disable them in Settings.

thank you, will take care of the things listed.

there are so many great custom roms to try, some cm based, some not, and most if not ALL of them do not have any of the issues you are complaining about.
its a Nexus; root it, and start trying the dozens of custom roms out there..
dont bother decrypting; its a hassle with zero real world benefiits, aside from back up speed, which is meaningless imo
and, all the custom roms pretty much update constantly, so rarely are you more than a few days/week behind any google updates when you use a good rom; the dev's make sure they update/add any real improvements/features really fast.

Note 4 T-Mobile 32GB Random Rebooting/Slow

Hello my Note 4 is randomly rebooting all the time (it occurs randomly) and is slow (sometimes) when I use apps like messages, browsing the web etc...
I'm on the 6.0.1 marshmallow
I installed the clean master and battery saver apps and things were alittle better but it still is slow and restarts plus those apps are filled with spam and virus links so they will be deleted.
What are my options here to get this note running like new again?

First of all you delete apps like clean master and battery saver cuz this app killing your processor ram and battery .android 6.0 is very well optimized and it can handle everything without any 3rd party app. Just make factory reset,disable apps you dont use ,do not install junk or ram cleaning apps or even battery saving apps,android Marshmallow allready has doze feature that save battery while you are not using phone and goes to deep sleep. go to settings/battery/detail and you will see all apps are in doze.

Any answers on the gentleman's inquiry though? I have a T-mobile Galaxy Note 4, and after having the phone for 1 year and a half, all of a sudden it started acting up last Thursday while I was running my stock 5.0.1, I had it rooted and TWRP on it since I bought it. The phone was a GREAT acquisition and I've always been an Android guy and started to learn about flashing, rooting and XDA since I had my S, S2. I thought that by simply upgrading my 910T to the new MM 6.0.1 everything was going to be taken care of and fixed, but boy was I so wrong.
Could you shed some light on this issue on this great phone?

I think he answered pretty well. You should understand that these phones are, in essence, small computers. And like a computer, the phones will become fragmented and bog down overtime. The solution is a complete format of internal storage; wipe everything, format, cache and start from scratch. Odin is the best option so learn to use it if you haven't already.

Thanks for your reply, however I asked the question to the gentleman as he only said to remove all of those junk third party apps as they were more harmful than anything else. I appreciate the lecture on what constitutes a phone, but I am very aware of it as well as being comfortable of the use of Odin and the rest of the steps. I have already done all that you suggested and the issues still occur after a week. Once again, I appreciate your reply.

No problem. Response was not only intended for you but other members as well since you aren't the only one having performance issues. Only suggestions, you can take or leave whatever you'd like but you might get better results if you try harder to be a nice person.

True! I stand corrected sir. I appreciate your assistance.

Hey guys, so today I tried a different battery cause my was bad and overheating and I can tell this one is good because it also is charging faster than before.
Now I did delete those apps clean master and battery saver like I said I would but I'm still getting random rebooting and slowness, one example would be I was typing a text and the phone took awhile to catch up to my typing and suddenly it restarted itself.
I'm not rooted and my rom is stock. Noticed today that my water indicator underneath the battery has triggered.
So I'm still looking for options...let me know, thanks.

WiFi Turning Off During Deep Sleep

Hi all,
Can anyone help with this issue. I can see no long discussion about it which seems to suggest it's either rare (not great) or something I am doing (probably).
My WiFi status appears to be fine throughout the day, when in regular use. I have no speed issues (connection speeds as expected for my home internet), no random drops or on/off switches and no seeming battery drain. I have all additional services on (Bluetooth, location and NFC as I want the phone to be fully functional at all times and not just 'look nice') and despite this I get what I would expect in battery life (c. 6 hrs screen on time). YET, amongst a few other problems (what is the slider customisation about - awful!) the one I can't fathom is this:
My WiFi switches off over night presumably when the phone goes into deep sleep. I have gone into the advanced settings and set it to 'Always on' but this doesn't seem to keep it 'always on'. I wake up in the morning and it is off. I was running some Tasker profiles (which seem to make little difference given the slider issue noted above) but actually my WiFi isn't one off the Tasks effected by a night time profile.
Any help would be appreciated.
AS a secondary question, I switched my VPN over to Canada as suggested and was provided with the Nougat update. I haven't yet tried it but was wondering if there are any bugs that I should consider before switching over given I am 4 days into owning this phone and still haven't ironed out certain things in Marshmallow.

Just as a follow up question, would the 'turn Doze off' option help with this? Surely I shouldn't have to do this though?

Am I the only one having this issue? That would suck. Even so, would anybody more adept at these things than me like to have a guess at solving the issue.

IV had agresive dose mode on and haven't had any wifi problems but I am on 4.0.1 so might want to just update it as it's really stable and I haven't had any issue except having to reconfigure the APN settings. PS if you do update reset you phone after as some people have said it helps with the new file system.

This happens when people is crying about updates every day. Then, when the updates are available, they update it in the first minute and again, they start crying, that they encounter bugs and stuff that doesnt work as it should, even if they dont have any idea how to revert their OS to the previous working one. People should learn how to be patient and enjoy their phones without being so greedy about updates.
Just sit tight, enjoy your phone, READ forums about latest updates and the problems encountered on that specific update ( since its still a beta update, and an early one , called Beta 1 ). If they seem to be fine with those issue, ONLY then should update to the latest one.

I haven't 'cried' about anything, pal, so keep your unhelpful comments to yourself or help. Don't middle ground-it by offering your own personal, and incorrect, opinions.
I hadn't upgraded anything, I was running stock OS and stock marshmallow, so I had literally done nothing to my device other than switch it on and download the same apps I've been using for years.
I've also rooted several devices in the past with no issues and chime in when I can to help, but I'm not a dev and there are far more technologically gifted individuals operating in this forum which is why I sought help here... Not that I got much from you. But I'm more than capable of reading release notes and making sure I can revert backwards before installing anything.
Now to anyone still here, and with the same issue, it appears that carrying out the update to Nougat, re-adding my WiFi networks and clearing system cache solved the problem or at least for the first night. Should this change I'll update here.

Hi Iso, thank you for your response, I hadn't seen this until now.
The upgrade to 4.0.1 does appear to have done the trick somewhat as it stayed on overnight without issue. I did notice it wasn't on a little later this morning but I am giving the device the benefit of the doubt on that one as I have been messing about with certain things and it's possible I or a profile in tasker switched it off.
As an aside do you recommend any other potential fixes, just to be on the safe side.

Did you factory reset after upgrading? Other than that it's probably a app you have I hear Facebook is really bad at battery

I didn't factory reset, only Cache wipe after the upgrade, and as it seems ok so far, I am reluctant to factory reset the device as it took so long to set up in the first instance.
Should it start becoming an issue again I'll try it but for now...
Also I know there are backup options though I haven't found one that works flawlessly which gives me the confidence to explore this avenue just yet.

You might have to because in nuogat they optimized the file system and in order to get the new one you have to factory reset not 100% sure it affects battery life but it really affects performance, PS also try turning off gestures, ambient display and pocket mode

Are you sure ISO? The UI has been updated and the already snappy OS feels snappier. Is there a way to tell for sure if it's required?
If so, any good recommendations for backup capability. I have used Helium to mixed results and I can't use Titanium as I have no root (and don't wish to).

Maybe not but it all elts fails

Need help solving an issue, play store misbehaving on my SM-T810

Hello, I hope I can post this here.. i tried, i searched... can't find any solution to my issue.
Model : SM-T810 , with Samsung 128GB UHS microSD. OS : stock Nougat from Samsung.
Here is the problem :
On the play store, if there are pending updates, they only install one at a time, and then it won't do more. Like if there is 5 pending updates, it will maybe do one, and then the other 4 stay pending. It might only do the download portion of the first one and not go to the install phase. If there's no pending updates, and i try to install an app, only the downloading portion of the process shows up, it stops after that, it doesn't go to installing. I have to close the store and go back in for it to install, but if there's a queue of downloads (updates or asked to install multiple apps), I have to close the store for the same amount of apps in the queue for them to install one by one. Now I noticed that every once and a while, 2 or 3 will have updated overnight but that's it!
I closed the process, I cleared the cache, I cleared the data, I cleared the download manager's data and cache, i rebooted, i forced a wrong date and time then set it to auto-date and time to retry, etc.... I uninstalled the Play Store updates, nothing worked!!!
The next step was to do a factory reset. I did not want to lose some progress on some games, AND I have an app to read PDF files and did not want to lose read/unread status of my files...
So I used Odin to flash TWRP, did a backup, rooted, used Titanium Backup to backup my apps.
Then I did factory reset. Store behaved normally again! Installed a few apps, waited a few hours, still good. Did a restore of my apps from titanium backup, everything seemed fine, then a few hours later, store still was not updating or installing the apps right...
Did another factory reset, store worked fine, only restored a couple of backed up apps (the critical ones that i wanted to keep the saves from), everything worked fine. Over the course of 24 hrs, i re-installed a bunch of my regular apps via the play store. Play store worked fine. I did to another Nandroid backup with TWRP just in case.
Then all of a sudden, it started to lag a bit between clicking install, to downloading, to installing. And then a few hours later, issue completely came back, store won't install without me closing it between the download finish and install.
Now one of the last steps I did before it started acting up again was moving ONE app to the SD card (not using any root features). I'm not sure if that caused the issue to come back.
I did notice that Android left a bunch of files on my SD card, some Android folder, with a bunch of subfolders.
I'm wondering if the SD card could be the culprit... I will do one last restore from my last working Nandroid backup and not move anything to the SD card.
If it comes up again, i think i will move the data that i have on my SD card that I dont want to loose (my PDF, pictures, etc.) on to my NAS, and do a factory reset without the SD card installed. Maybe even re-flash with Samsung Kies... and forget about my Titanium Backup saves...
It's my last resort so I was hoping anyone would have any idea on what else to try before doing that?
One last point : yes the stores kinda slows down at some point where the download process takes a few seconds to kick in, and then a few seconds to installing, up to the point where it never does. BUT the rest of my tablet still is really fast, no slow downs anywhere else... All apps launch fast
Thanks!

Auto updates are bad. They just kill the performance of your s2.. better do such things manually.

Auto updates of the apps? Or the OS?
Apps i can see... but still... If I turn that off, that solves the issue of the auto-updates. But then if I want to update a bunch, they will only do one by one, i have to close the store and open again after each updated app.
But even with app auto-updates, if i want to install one new app on my S2, it will only download, but not install, i have to close the store and open it again for it to install. Then the next time that I want to install an app, I have to do the same thing again, close and open. It's like the download manager doesn't tell the Play Store app to do the install (or tell whatever app or service to install the APK...)

I would check for OTA update but since i rooted mine, it won't do them...
I'd have to flash the stock rom from samsung again and loose my saved data... which right now i might be OK living without...
Anyone knows if I loose TWRP if i flash a stock rom with odin ? If so... am i better using Kies?

Fair, let's recap: you do not use stock rom. You have root, twrp, flashed this and that and a morbid desire to have always the very lastest version of whatever the app. And now the Play store doesn't work properly anymore.. d
Do you see the pattern?
But, hey, maybe you need even more *lates updates* to fix your issue.
Updates = bad performance and new issues in general. Period.

Wooooh, DON'T jump to conclusions here.
I was running the STOCK out of the box Android for the S2, no root, no TWRP. The issue started after one year of usage, and not only included updating apps but installing FRESH NEW ONES TOO.
The "flash this and that" came AFTER i ran into issues.
I also have a Note 5 supplied from work and for that reason I'm still runing stock, not rooted, and never will root it. I have over 100 apps on there, 5 email accounts (2 professionnal, 3 personnal), multiple google calendars, multiple outlook calendars, auto-update is on, it's been over a year and a half, if not more, and never ran into this kind of issue, ever! It's synced with my CPAP, my smart watch, and my headphones. And it's still goes the same speed and gives me the same performance as when i took it out of the box.
My tab S2 is my second Android tablet, before I had a Tab 3 that never gave me issues like that either, and always had auto-updates on.
Sometimes you need updates. Some online services might not work right or at all if you don't have the app that matches the features, like evernote, facebook, onedrive, dropbox, etc...
Or you get new hardware that requires an update.
Yes sometimes they include bugs ... which are fixed in a later version.

I saw multiple posts of people having different phones running stock having this exact issue for a while with no solution in view. I think it has to do with Nougat too... But my Note 5 is on Nougat and no issue... it might be brought on with specific services or apps running while on Nougat.

Thanks for letting me know about the OTA update. Since i was rooted, i can't get OTA updates, would have needed to wait for the 7.1 Rom to flash...
I ended up taking screenshots of the stuff i didnt want to loose (read/unread status of my pdf files, nevermind the save games) and then i used Samsung Smart Switch to reflash the whole thing back to strictly stock, lastest firmware. So far so good, crossing fingers

Fair. So in this *year of usage* you never ever updated the OS?
And auto-update was of course *off*, right?
If that's the case, then clearly there must be some other issue with your s2.
Otherwise, you have merely confirmed what I have told in the very beginning: updates = bad performance and new issues in general. Period.
By the by, apps like evernote and facebook track and spy on you.
About your Note 5, maybe there weren't so many updates..

And auto-update was of course *off*, right?
If that's the case, then clearly there must be some other issue with your s2.
Otherwise, you have merely confirmed what I have told in the very beginning: updates = bad performance and new issues in general. Period.
By the by, apps like evernote and facebook track and spy on you.
About your Note 5, maybe there weren't so many updates..

Yes in that year of usage I upgraded the OS from 5 to 6 to 7. Yes auto-update was on, for Android and for my apps. By stock rom i meant nothing flashed "this and that" like you said.
If you would read my other comments, you'd also realize that another member helped me more by letting me know there was an OTA update that helped him. I reflashed my S2 with Samsung Smart Switch and haven't had any issue with the Play Store since... that proves that updates do fix issues.
There's no OS versions, app versions, firmware versions on any devices that don't have any issues whatsoever. Updates might bring bugs but they also fix the ones from previous versions. If you think that anything stock out of the box never have any issues whatsoever, you're wrong.
Apps like evernote and facebook spy and track you? Really? And you're on a forum for Android based product and don't think that Google tracks what you do? If you dont sign in with your google account and only browse the web with your tablet, that's your business, but you can't go on forums and admonish people for doing otherwise.
Besides, this is a forum where a good part of the posts are about custom roms, flashing different boot/recovery loaders, different kernels, unlocking phones... and you're judging me because i do app updates, and flash "this and that" ?
Come on...

No judging here. Just pointed out the probem at hand.
You did update the OS at least twice.. see?
OEM updates = bad in general.
Sure, new updates fix what *previous updates* screwed up to begin with; sometimes.
I totally agree that there is no OS version that is 100% issue free, but -- why trying to fix something that seems to work?
You see, that is my whole point.
I told you about evernote and facebook because you mentioned to have them on your Note 5 which happens to be your professional work phone?!
Just be aware that Evernote steals content just like the FB messenger. And I mean literally. Your creative ideas become their property. You did agree to their terms! FB also records the mic(s) 24/7.
Certainly Google tracks and spies as well. Then again, you can deactivate or block (firewall) those services/apps.
Just remember, things that are *free* come with a price.

Niii4, I tried to subtely pass the message that I did not want any of your help when I said that SOMEONE ELSE helped me with their input and update.
I didn't say that I was using evernote and facebook on my Note 5 from work. Jumping to conclusions again.
You want to know what are the biggest secrets in my Evernote notes ??? RECIPES!!!!!
Oh no... they can read the oh so secret lemon crinkle cookies recipe that is available with a quick online search! Here's the link btw : http://www.laurenslatest.com/lemon-crinkle-cookies/
I came here after trying a lot of troubleshooting steps, when everything that I've tried failed. And someone else helped me.
All you brought to the table was misinformation about updates in general and spread paranoia on who is spying on who.
fonetyk asked you to stop that, and I asked you to stop that. So far my issue has been resolved and i'm thankful to the user Tabpro8.4 for his comment.
Please, please leave my thread.

First and foremost, this is a forum and thus other users that may encounter similar or the exact same problem(s) will seek to comprehend the whole issue at hand and not just one side of a problem.
Oh yeah, an OTA update seemed to have fixed it. Seemed.. for now.
Second, this is not exclusively about *helping you*. Apparently you are quite knowledge resistant, especially when facts are being stated that don't conform your general view.
True, you only have hundreds of apps on your work phone. But definitely not FB messenger or whatnot. Whatever. What's right is right, and what's fair is fair.
I suppose, you are probably right, the work you do must be of no interest for anybody in this world; at all. Same for your private life. Now, be a neat little sheep and go on chewing the green.. (while we are watching you).
Oh, and you stalking all my comments, telling people to ignore me is hilarious. Keep up the great whine. ?

Lol... knowledge resistant. Thats cute.

Stalking your comments... ah! Maybe you got that dead pixel from trying to plug your bluray player on your tablet. Seriously clueless or just trolling...
My issue is resolved so im unsubbing from this thread.
Bye bye :good:

"Battery usage data isn't available" /data/system/batterystats.bin -daily.xml etc

"Battery usage data isn't available" /data/system/batterystats.bin -daily.xml etc
Got a "new" left over stock Nexus 6 through Ebay, installed lineageos 15.1 nightly, MindTheGApps, root, radio, bootloader. Everything seems to be working nicely, except the Nexus 6 runs pretty warm rather quickly after using it, and I find that the battery is draining pretty quickly. In standby mode it doesn't drain quickly.
But I get no access to battery stats in the settings, because under Battery, it says "Battery usage data isn't available".
There has been talk about this before, but it's all pretty wishy washy. Some people apparently had success by using recovery to clear the cache. Others deleted the /data/system/batterystats.bin file using the battery calibration app from the play store (I know I know, there is no such thing as "calibrating" a battery, but it's just used a tool to delete that file in this case), the one that happens to mention batterystats.bin in its description. Others simply waited a while, and others ended up reflashing. Short of reflashing, nothing has worked. I've tried to manually delete that bin file using Termux and then rebooting. I can see that the file gets regenerated upon boot. What is the reason why the Settings/Battery feature can not show any of its details?
Aside from batterystats.bin, I also see batterystats-checkin.bin and batterystats-daily.xml. Does anyone know anything about those files, and could I perhaps delete them all (or rather, move them into a backup folder so I can place them them if needed), without bricking my phone?

Try using acubattery for some days and see what condition the battery is in. Even if the device is new, left over stock, the battery might really be damaged.

I'm installing that now, thanks.
I just found this: (I'm not yet allowed to post links), youtube: v=dZL2LDAg5cs
So, in developer mode, Android can produce a bug report zip file that you can upload to a special website, that is able to pluck detailed battery usage data from. I wonder if there is an app that can do that instead. I suppose that app would not be able to directly show this kind of detailed information, but would have to be pointed to a zip file that the built-in bug report developer feature stored, eg, in the Downloads directory.
All this is only needed to troubleshoot what the cause of the battery drain is. But yeah, it may well be that the battery is old and stale or whatnot, even though it has not been used for like what, 4 years since it was manufactured. Interesting to find a "new" unopened sealed Nexus 6 on Ebay in 2018 though...

In your first post, you indicated you installed bootloader amongst other things. Did you mean boot? As in a third party kernel? If you really meant bootloader, would you go into more detail on that.
When you first turned on the device, what version of Android was it?

I followed the official instructions on how to install LineageOS 15.1. Part of that was flashing the bootloader using fastboot.
I just checked my phone again. It still says "Battery usage data isn't available.".
Accubattery was showing many details on how different apps were using power, but now it's only showing 2 entries. One for settings, and the other "Trebuchet" which I think is the camera app that comes with LOS. Oh, AccuBattery itself spontaneously joined in the list.
Anyway, I don't expect Android to work all perfect, because it's clearly one big pile of make shift goo. Nothing ever works right on it. You have to literally babysit the damn thing fighting problem after problem after problem.

Trebuchet is the LineageOS stock launcher.

i have this same problem with my Alldocube x, it drains pretty quickly and heats up enough I had the urgency to shove it into the freezer, sometimes I stick a block of ice cube on the back metal to counter the heat, I am only using youtube.
Along with this annoying heating problem is the battery drain and no battery usage problem.
I also tried resetting, reformatting, clearing cache etc.
im loving the Tab S4 screen on this and I cant go back to petty LCD tablets.
