Hi all,
Firstly, apologies if I have posted this in the wrong area & if this has been covered a number of times before.
I have had a Nexus 9 for the last 18 months, since the upgrade to marshmallow, the tablet is sooo laggy and at times completely unusable. I have tried wiping the cache partition and that helps for an hour or so but then its back.
I have also read, some people have put a custom kernel on and it has done the job.
Being rather new (but capable) to custom kernels, i am hoping for some straight forward guidance to which is the best kernel to put on and perhaps a how to guide.
Thank You
Just realised that this should be in the Q&A thread. Not sure how to move it myself, but if an admin/moderator could do it I would be grateful.

Have you considered going to nougat? You don't really say how long you've been having the issues. Mine started lagging after about 6 weeks of getting it (over two years ago). It also locks up quite a bit. It used to spontaneously reboot. My solution was/is a complete wipe as in factory reset every 4-8 weeks. Have you ever tried a factory reset? I do run ElementalX kernel but run stock OS as the custom ROMs I tried didn't help.

The tablet is on Nougat now. I've been having these issues for over a year now. I don't get the sudden lock up and reboot though.
Done the factory reset many times, will cache partition. I read somewhere that the custom kernel really helps.

It could be an app, or more than one. I run as few as possible. I stopped Facebook as it was an issue. My TouchPal keyboard also caused problems. When you reset, do you just let Google restore your apps?
As far as custom kernel, is your bootloader unlocked? Are you rooted? Wug's Nexus root Toolkit works well​ most of the time if you're not familiar with the darker (joke) side of Android.

Ive tried running the tablet with only stock apps after a reset.
I will try and be clear here, I have been through nearly all the common fixes (resets/app deletion etc) for having a laggy tablet, except the rooting etc.

You have one of the buggy tablets. Join the club. Now, the ElementalX kernel helps my tab, but it's not a fix--just a temporary solution which I've made work for me. http://www.wugfresh.com/nrt/. Start with this kit unless you are fluent in CMD prompt. If you use Apple, another approach is needed. I'll try to locate posts within this forum.

Nexus 9 slow
After suffering forever and trying everything to resolve my Nexus 9 slowness. I did a factory reset and wiped out everything and now it is as fast as it was new.
It might just be something you have to do periodically. EMMC storage chip performance often degrades in the long term if you don't do a wipe. This is the type of storage most phones and tablets use.
What I can suggest you is to reset to Nougat (7.1.1) and not install further updates.
I had your problem during the past years, but after the rest I didn't update anything and my Nexus 9 works excellently.

sorry ahead of time for the rambling and wall of text.
i have a few questions i suppose. im currently running the latest 4.1.2 release on my razr. stock. i went through 2 phones recently because the update was wreacking havoc on them. before the update i loved my razr. only issue i had was battery life, but i cant lie, was my fault for playing battery hogging games ALOT. lol. so, i got my latest replacement phone. i have the same apps as before, minus a few ive ditched. the phone is feeling laggy/sluggish now. it may partly be from tsf shell, which i love but would ditch if need be to get my phone back, even though it never caused lag before the update.
From reading around the razr isnt getting another update antime soon, if at all. its pretty much on its last leg, as theyre moving away from it im sure. ive tried numerous things to get it running a bit smoother and its helped to an extent, but there is still some lag.
my question is, whats the best way to go from here to getting it running better. ive been rooted before and tried different custom roms, so im not against it, if thats the way to go. if it is, what custom rom is best? if there isnt a 'best' which would you recommend i try? i guess a 4.2.2 rom will probly be suggested. what are the major differences in the 2?
thanks for any opinions and advice.
If it is running slow, you could always use an app like is monitor to see if an app has gone rogue and is using up lots of ram or CPU. I doubt its tsf, as I used that for a very long time on mine without issues.

Hey there!
First off, for the lagging problem, I'm positive that your phone probably needs to be cleaned up. The stock JB that you currently have is supposed to be the most stable one there is.
For cleaning up, just get SD Maid, and clean up using all the options available.
WAIT! Can I get one thing straight? You did do a factory reset before upgrading to JB 4.1.1 from ICS, right?
A LOT of problems sprout from this simple fact actually. A factory reset is mandatory when upgrading from one kernel and ROM to another, be it stock or not.
In Custom ROMs, we tend to always encourage full wipes before flashing one ROM over another unless we are only doing a minor, from let's say, Liquidsmooth v2.4 to v2.7. Then, only the cache and dalvik has to be wiped.
Yep. Hope this helped. If the answer to my above question is no (you didn't full wipe), the nI would just recommend you to use TiB, backup all your apps and data, then factory reset and then restore using TiB. That should help.
replying
the phone im talking about came from the manufacturer by verizon with 4.1.2 on it, so im not sure if it was upgraded that way.
if i have to factory reset, whats the vest way of saving game data so i dont have to start all over?
im currently not rooted. will root if its needed.
thanks for the previous info.
Hmmm. A sticky situation, TBH.
Maybe you can try rooting and then this app: https://play.google.com/store/apps/details?id=eu.thedarken.sdm
But I haven't quite got experience working with RAZRs which came with 4.1.1 installed..
So try out the app after rooting, and if that doesnt help, factory reset. Backup your apps and their data using Titanium Backup which is available for rooted phones.
If even after that things are laggy, then i suggest getting Liquidsmooth or MoKee Rom. They are pretty fast and lagless.
Hey,
I just received my Nexus 9 from Amazon and I'm happy with it, but I just can't help but notice the glitchiness of lollipop already! It crashes constantly, sometimes I have to reboot it just to get it working again.
Does anyone know what I should do to improve the performance? I'm happy to flash a custom rom as long as it's not glitchy as 5.0.2.
Thanks,

I've had my Nexus 9 for over 3 months and I've never experienced glitches, crashes or lag with Lollipop. I do with CM12 on my old HTC One X, but that's to be expected. I've always rebooted my tablets once a day, usually before I put it on charge (one of my OCD compulsions), so maybe that has something to do with it. I also did a factory reset on my N9 right after it updated to 5.0.1 and set it up fresh.
Might need to do a factory reset as I never had an issue while I was stock. I was stock for like a month and never had any of those issues.
I also have not had problems. As others have said, do a factory reset. If you still have problems, flash the factory image with fastboot. Then if you still have problems it's time to rma the device because something is wrong with it.

No problems with mine. Maybe some badly written apps are causing bad performance?

Like everywhere above, I would recommend rebooting the device. If that doesn't help, I would try to get a new one.

Just as kendrick8997 and others have suggested. I'm running stock (albeit rooted with custom kernels on most) Lollipop on an N4, N5, N7 FHD, and N9. No issues.

So, I've tried every which rom out there for the nexus 6p and got tired of dealing with sub par battery life, random hangs (albeit occasionally, but precisely when I needed it to not lag) and other issues. I even tried having 100% stock but with custom recovery and systemless root. Somehow though they were nice for a while they started to slow down and act up after a while. Finally I decided to go back to stock. Fastbooted and flashed stock from Google servers and even locked the bootloader and unchecked "allow unlocking".
I can honestly say that ever since then I've had zero issues and battery life has been phenomenal. No random lags or freezes or drain.
Perhaps this is how google wants the device to be used and stock Android has something in our that works properly only on a 100% factory set software.
Yea I miss the ios style emojis and ad bocker but at least now I can be rest assured about ota updates and using the device in the way google intended and thus having the best experience??
Also I think xposed is slowing down marshmallow and giving it some issues after a while.
What do you guys think ?
Sent from my Nexus 6P using Tapatalk
Using a Stock based ROM with root, Adblocker and some Bloatware removed works the best for me. I remember Xposed to be buggy since Android 5, this is why I never used it again. Flashing Updates is not a big deal if you know how to use fastboot and how to flash single parts of a factory image.
Same here dude I have had android phones since the g1 rooted so many. I even remember when Franco was starting out lol. But with the nexus 6p I feel stock is the best experience I have tried a few ROMs but stock is great for this device... Don't get me wrong I feel I need to sometimes try a rom but I don't as it's a hassle now. 100% stock here.
I'm a happy custom rom flasher! Rocking with Chroma for now & like Sinless .. XDA Development for the win!
I'm using Pure Nexus with no issues whatsoever. It's essentially the stock ROM with a few goodies added.
That's where I'm at too. Tethering works, Android pay works, I have no problems with battery. Couldn't be better. I do miss some of the root/ROM features like center clock, different pictures on lock and home, double tap to wake and sleep though
Pure nexus works for me. But yea each phone will be a little different.
Agreed.. I buy nexus so I DON'T have to root to get that experience.

Placebo...
Absolutely not my experience. Used the phone about one month with stock ROM and flashed Chroma ROM and Franco's kernel then. First thing I noticed was the device running much cooler!! Not a single problem here...
Hmmm pure nexus with ak gives you much better performance and battery than stock.... On screwd at the moment. Also very good
Stock is stock the way the device was intended to be used. Any changes will come from the source, "customize" someone else's work lol..... Riiiiighhhht

If you are happy with pure stock, that's great. May I suggest unlocking that bootloader though. I've read about a couple guys where an OTA failed for whatever reason and the phone will not boot. With a locked bootloader, you have no hope of fixing it.

I second this.
Battery for me has been the same. Also that white background settings UI I hate, black background just looks so much better
Opinion I know but it's an option is lose without root
Kinda Agree.. I'm on Chroma's Rom and not rooted. I like Chroma's subtle additional settings and stock kernel plus the Phone runs great. I will only load roms that use stock kernel because of lag and additional rom anomalies that happen when i need to do something...Ugh!
Choose your apps carefully, is my advice.
If you want to use facebook/messenger. Go for tinfoil or something like that instead. Also, disable the google apps you don't use. Maps can also be done with the browser and is one of the primary battery drains for example. Just like i noticed that since i disabled chrome and went for a chromium browser, battery life has gone up! Same with swiftkey instead of google keyboard, ecspecially with a nice black skin.
And yeah, use the drawer and dock for shortcuts, don't clog your homescreen with icons and widgets. That saves memory and thus battery power.
The thing i don't get though, is that with my z1 on 4.4.4 i could easily get 3 days with 5/6 hours screen on time. I really have to do my best to get that on my 6p. Even though the battery is 500 mah larger!

Thanks for the tip. That makes sense. Perhaps when ota update comes in and updates the factory recovery, it needs the "allow unlock" button checked.
Maybe that's why it was checked by default after factory reset.

Hello,
I have my original TF201 and it's between treated extremely carefully and not used a ton. So it's in perfect shape. I reset it sometime ago so that other family members could use it as well. It's back to factory reset with the latest official update on it. I installed several apps that I would commonly use and the performance slowed to where is literally unusable. Clicks take forever to register, pages take minutes to load, etc. I uninstalled as much as I could and that helped somewhat but it's nothing like the performance it used to have. So, from what I've read, I'm thinking that the performance of that last official update is the problem and it might be time to get into rooting and flashing a different ROM. I've rooted before but it's between several years so I'm not an expert.
I just wondered if this sounds like the best thing to do for my performance issues. If so, which ROM would you recommend? I'm not stuck on any particular version of Android more interested in what your experiences are with which ROMs runs the best on this unit. If KatKiss is recommended, would you go for V30 or one of the older ones? Another post said that, at that time (maybe two months ago), people were having issues with V30 and I'm not sure if those issues have been resolved. I'm OK with a Marshmallow, Jellybean ROM too. Just any help on which direction to go would be really wonderful.
Thank you so much!

I found Katkiss LP v26 worked really well. I am now on the Marshmallow version #22 and so far that is really smooth and quick.
Make sure you upgrade to the right bootloader then follow the instructions in the Forums to the letter.
Good luck
I am currently using KatKiss v30. Was in a similar situation to you where my Prime got very little use due to being slow / unusable. KatKiss v30 has been pretty stable for me as long as it is kept below 1.8Ghz, highly recommend trying it out if your Prime is anywhere near as bad as mine used to be.
KatKiss v30 is the way to go !!!!!!! really not much of a difference in user experience with my galaxy tab s2 ))
Hi guys,
I'm sorry cause asking this, especially cause this question has been asked manytimes and I have read several subjects too, but I didn't strict answer I'm looking for.
I recently bought nexus 9 (WiFi only model) 16gigs,
I unlocked bootloader, I rooted the device and now I want to debloat it.
I'm in dilema weither I should just have it rooted and debloated on 7.1.1. android, or should I use some of the custom roms around.
I'm aiming to use tablet mainly for gaming. I have servral games I'd like to play listed:
Marvel Future Fight
DC Legends
Star Wars Galaxy Heroes
Star Wars Force arena
and few others but i take it that if those can run fine, all others would too.
Also can someone point me to a safelist of application that can be removed if answer to first question is to just leave it rooted and debloat.
Thank you a lot for help.
Cheers.

For the best performance, install a custom ROM. As for debloat, ... It's a Nexus, what bloat?
But if you want minimal, I would say flash slimrom and the smallest gapps package that fits your needs. Or go gapps free and use micro g instead.
Performance on stock is pretty bad (really bad), but a custom ROM will fix it for the n9. When I say bad on stock, I mean opening more than 1 tab in chrome, it has to reload the page every time switching between the two. Same with having a couple apps open.
Fortunately, most of the ROMs out there take care of all that.

How would someone find official roms? I used pure nexus rom thinking that is official but i guess i was wrong. I not to big on roms knowing. They all looks the same to me I just care to be able to uninstall builtin apps i don't use and that everything works fine.
This one i use now had a problem common with nexus 9, white blocks and anoying skrechy sound, but i read somehwere it is fixed by unhoking battery, cleaning pins and putting it back together. I tried it and I didn't have problems since then. I drained battery to 2% no problem, before it was impossible. I have no idea was it ROM issue or what.

But it's safe to say that it's fixed now. Everyone was talkin about disconnecting battery, and clean a bit and connecting again.
it seems such a easy troll solution to this "very anoying and hard problem that even HTC didn't solve", and i did it and it really did the job (knock on a wood ). I've been draining battery to the end for 3 days now, nothing ever like that happend ever again. before it wasn't even a day when i didn't experienced that problem.

Good to hear. That usually is the fix for that.
Please, just to confirm, is this "image-volantis-n9f27l" official ROM or it's custom ROM?
I also use this bootloader : "bootloader-flounder-3.50.0.0143" since other ones didn't work for me.
I was with support trying to solve issue of Device restarting every time I install new app or update app, and while trying to clear cache partition, it gone to my device not wanting to boot. so i had to factory reset, and it still won't start android in full. so i have to reflash ROM. I guess.
I'm kinda lost now cause i don't know what to do.
As said i just want for my device to be rooted so i can delete all apps i don't need and change launcher (deleting existing one - well i don't know if it's smart or not. i figure why having two launcers when i will use only one).
And i want to play games and use apps without it failing on me all the time.
