These are screenshots of the v500 and then Nexus 9 after boot both running cm13. As you can see, the v500 is consuming much less RAM. :angel:
[Nexus 9 General] madbat99:
It's not RAM. It's all because of the translation needed from nvidia chipset. Period.
[Nexus 9 General] Masteryates:
I think you are correct to some extent. It's also RAM though as the Nexus 9 constantly runs out and has to employ tricks like zRAM to help it out. On exactly the sam ROM, my v500 has way more RAM and doesn't even need zRAM. On stock, the Nexus 9 doesn't use zRAM and then force closes things when it constantly runs out. That's why people are experiencing chrome tabs refreshing and launcher redraws. :rolleyes:
[Nexus 9 General] albsat:
I wish we could have upgradable memories as users on the tablets one day..
[Nexus 9 General] kacang87:
I think nexus 9 should have better ram management..lets wait for nexus 7 2016 by huawei,with nvidia X1 chipset and 4gb ram(rumour)
[Nexus 9 General] wilkster:
According to https://blogs.nvidia.com/blog/2014/08/11/tegra-k1-denver-64-bit-for-android/ there is a dedicated 128MB optimization cache used for the code translation in the tegra chip in the nexus 9. So I think everyone is correct. Less available memory to go around.
[Nexus 9 General] Masteryates:
I'd prefer them to put in the sd820 personally. 4gb would be excellent though. :angel:
[Nexus 9 General] ewa12321:
I dont think more RAM would change anything. I was reading Samsung S6 posta that theres redraws and bad RAM memory management. On other devices theres same issues, apps closed too fast, homescreen redraws etc
[Nexus 9 General] Masteryates:
Its a different issue on the Samsung devices. They sell you a device with lots of RAM but then don't let you use it to conserve battery life. My friends S6E starts force closing apps when just over 2GB Ram has been consumed. At least they have to choice to use it all in custom roms etc. We are just stuck with zRAM at best. :crying:
[Nexus 9 General] NYCHitman1:
Yeah, Google needs to stray from the Nvidia disaster. Safer to go with a more reliable chipset like Snapdragon.
[Nexus 9 General] Masteryates:
Yes, its no coincidence that the N7 2012 was crap, N7 2013 is still excellent and the N9 is crap again. ;)
[Nexus 9 General] NYCHitman1:
FWIW, I love my Flounder (Nexus 9). If you're someone who likes to stay on stock, this device just isn't for you. I've been able to annihilate many of the issues that plagued this device since day one with some kernel modifications and can now enjoy the tablet as it was intended. I still think that the Tegra platform sucks and has a long way to go. I've owned way too many Tegra devices and have been burned by them all. Lesson finally learned, but there are plenty of things a user can do to change that if they are one of the disgruntled folk.
[Nexus 9 General] Masteryates:
I know what you are saying NYC.

It really annoys me that Google aren't taking notice of the tricks to make the n9 work better and incorporating them into there new builds.
[Nexus 9 General] NYCHitman1:
Well, it shouldn't annoy you. It's a developer device. The main purpose of it was to give people the ability to easily tinker. If you're someone that isn't tinkering, not much purpose in owning a Nexus 9 (or any Nexus, for that matter).
[Nexus 9 General] Masteryates:
In the days before the Nexus 4, I would agree with you. I bought my Nexus 5 as it was the only device that was running stock Android at the time with no bloat to slow it down. That's the experience I was also expecting from the Nexus 9.

For me, I'm almost glad that I've had to tinker as I learnt so much. For my 65 year old mother however, she was expecting an experience like her Nexus 4 and is really disappointed.

Come on Google, sort it out.
[Nexus 9 General] swaaye:
I like the Tegra Note 7 and Shield Tablet. Especially the Shield Tablet because NVidia has supported it extraordinarily well. Better than even any Nexus device AFAIK. It's fast, stable, has top notch graphics drivers, etc. The gamepad-mode / console functionality works great too (as does their actual gamepad). It's an interesting study of what can be done with their own device which has no other vendors in the way of fixes and updates.

I think a lot of performance complaints with tablets in general have been caused by the OEM using a very cheap, very low performance EMMC storage solution. This causes the stuttering when apps are hibernated and reloaded later, and when you install apps and the whole system stutters.

The worst tablet I've ever owned would be a dual-OS Onda V919. It had a terrible Realtek wifi chip that had problems with many access points. The touch screen would "overload" and stop responding. The tablet would sometimes overheat and shutdown, especially in their lame Android 5 implementation. I edited conf files and fixed most of that. The Samsung 2048x1536 panel was wonderful, but that had a plastic face over it that scratched easily. It did have a fairly fast 64GB EMMC chip that was fast enough to even make Windows 8/10 enjoyable though.
[Nexus 9 General] the.teejster:
Would you mind sharing your setup (ROM, KERNEL + mods implemented) with us ?

I've always been on stock and am tired of the constant freezing / lag that plagues the device. Since support has officially ended I'm ready to flash whatever works to make this tablet run the was it was meant too.

Thanks in advance !
[Nexus 9 General] NYCHitman1:
I no longer use the Nexus 9. Upgraded to the Pixel C, so my N9 collects dust. However, I was using my own work when I was using it.
[Nexus 9 General] swaaye:
I have mine on official Lineage 14.1 and that seems fast and smooth to me. Using their kernel or ElementalX kernel doesn't really matter. As long as you also flash SuperSU, or use the Fire-n-Ice or ElementalX kernel, one significant speed boost comes from not being forced to encrypt the filesystem as on stock. This has been a cause of poor storage IO performance on a number of tablets. Poor storage IO performance is a major cause of stuttering and pauses.
[Nexus 9 General] madbat99:
The best, stable performance I've had was the last build of Dirty Unicorns (they stopped support now though). Right now I'm using pure nexus ROM and it's very nice. No studders or lags. When coming from stock, pure nexus will appear to fly. You will be quite impressed by the pure speed at which things open, and task switching.

Unfortunately I'm starting to get symptoms of poor build quality in this tablet though. USB port is beginning to fail (otg flash drives/sticks only work with some wiggling and tapping) and now I'm getting some bubbles in the corners of the display. I thought for awhile that I was one of the lucky ones... Nope.
[Nexus 9 General] swaaye:
Build quality problems suck. But I'll let you in on a secret.... Don't expect any tablet to be terribly solid. lol. Really though they all fall apart. They're all fragile. They all have some kind of frailty. I have a Surface 4 Pro and MS didn't really spare any expenses there and yet they have still been fraught with issues. And Android tablets are really designed to be obsoleted anyway. Maybe 2 years of support and then you're supposed to toss 'em and sign up for the next big spectacle. So I try to buy them second hand for cheap because they don't really have much value in my mind.

I think most of the speed boost people see with 3rd party Android firmware with N9 is the removal of forced encryption. Pure Nexus is another that disables it.
[Nexus 9 General] madbat99:
Agree 100%. Didn't get mine used, but on sale. Still like$350. Passed my n7 (2013) to my wife when I got the 9, that thing's still solid. Replaced the screen (my fault for dropping it), and it still looks new.

I think the animations are sped up on purenexus too. But it "feels" faster. It ought to be a great change for the guy coming from stock, no page reloads or redraws either.

I really hoped this thing would hold up as good as the 7. Admittedly I do drag it to work in my backpack everyday. Long drive to work so I watch movies (I know, safe right). Gonna change out the USB daughterboard this weekend, and likely the screen if I can find one cheap.
[Nexus 9 General] the.teejster:
Thanks for the feedback folks !!!

I'll likely try out Pure Nexus in the coming days. I prefer not to root my device so the only thing holding me back is losing progress I've made in some games I enjoy playing. But the lag / stuttering is slowly taking it's toll on me so I'll likely concede and take the plunge soon.
[Nexus 9 General] the.teejster:
I took the plunge and installed Purenexus last night... So far at least, the tablet seems much more responsive. I got a little scare when beginning the installation and having TWRP appear to be stuck at it's boot screen, but after some research found it was normal to take a few minutes to load.

When going through the setup process I chose to restore my apps / data from my google account and was pleasantly surprised to see a handful of apps / games actually had their settings and progress retained ! Looks like Android is getting better all the time.

Lastly, I thought after going through this process that my tablet would be un-encrypted now but that is not the case. Further research indicates that in order to remove encryption you have to FASTBOOT FORMAT USERDATA. Not a big deal as I've read time and time again that this tablet has hardware based decryption so there would be little to no noticeable impact.
[Nexus 9 General] evolucion8:
I sold my Nexus 7 2013 for this Nexus 9 and what a big mistake. The stock ROM is horrible. Tried different ROMs and the one that gave me the best results was the Omni ROM, will try SlimROM today. I used Elemental X kernel and improved slightly compared to the stock kernel on the Omni ROM but no difference RAM wise, used ICE and Fire Kernel and the memory usage is higher as it keeps more stuff on memory and hence, better multi tasking but its not stable enough, it would just reboot for no reason. So I will try SlimROM today with the default kernel but this time I will edit the Low Memory Killer configuration to force the software to have around 96MB of free RAM on the empty apps parameter as this tablet needs RAM (64-Bit OS overhead, Binary Translator which steals 128MB of RAM)
[Nexus 9 General] swaaye:
I'm sure you can format in TWRP too.

Full disk encryption has other overhead. All data goes thru CPU instead of just DMA. Etc. It will affect battery life and performance to some degree no matter what hardware acceleration is in there.
[Nexus 9 General] madbat99:
As [MENTION=3809589]swaaye[/MENTION] mentioned, TWRP format of data is available. Not just a wipe, but format data. Then setup after flashing a ROM that doesn't force encryption.
[Nexus 9 General] the.teejster:
Thanks for the feedback folks ! Much appreciated.

Last Question RE: TWRP... If I backup my (encrypted) data partition, format it in TWRP (to a presumably unencrpyted state) and then restore my backup, will the end result be a encrypted partition ? I'm assuming the answer will be yes but hoping it will be no ;)
[Nexus 9 General] Hans5849:
This tablet has gotten worse and worse with every software update. It has gotten slower and slower, bought it because my M8 was a great phone that held up fairly well considering my usage. The N9 though is so laggy at this point that the only thing I can use it for is an alarm clock, and that's only if it's not booting then immediately crashing.
[Nexus 9 General] madbat99:
Yeah, custom ROMs are the only things that make this old girl useful at all. Running slim7 right now. It's not loaded with extras, hence the name "slim", but it definitely helps the performance a lot.
[Nexus 9 General] Xaiux:
Is it worth picking up a Nexus 9 these days? I'd probably load LOS on it right away.
[Nexus 9 General] chrisclaytonnz:
Don't do it. Even with LOS it freezes and is slow. I'm trying to find viable cheap alternative. Thinking might even go back to iPad as almost no Android tablet are any good.
[Nexus 9 General] albsat:
If the price is OK for you , the latest nougat run so much better in N9. Try the [MENTION=5501864]USBhost[/MENTION] asop version. It is really stable.
[Nexus 9 General] jib@rmi.ge:
My experience: never used any custom ROM, just the ElementalX kernel, with maximal overclocking, and it really flies! Oh yes, and Greenify of course, for decent battery life. Yes it heats up, but then, all devices I had do that.
[Nexus 9 General] madbat99:
No need to stress your CPU like that with crazy overclocking a kernel, when just a few tweaks and a good ROM is so much smoother.

[Nexus 9 General] tetebueno:
Hi, it's not hard to understand why I ended up in this thread,so here we go...

So I tried changing the density since it's a harmless change that doesn't involve flashing or stuff (I now like things just out of the box, no more flashing ROMs for me); I picked 288 after trying a couple, and this did show some improvements in performance (no benchmark involved, just how others and I perceived it before and after).

It was awkward at first to get used to the little details that change after applying this, but I already forgot which were them, so I'd recommend this too to anyone who still want to make use of a device with so potential.

For the ultimate noobs:

Download adb in your computer (sudó apt-get install and),

enable developer options in your N9,

enable USB debugging

and run the command (use the full command so device reboots by itself) in the computer having the N9 connected to the computer:

adb wait-for-device shell wm density 288 &&
adb reboot

This is supposed to mess with the density of pixels per inch on the window manager of the tablet making it lighter for the OS to handle screen redraws, nothing hardcore, no worries.
[Nexus 9 General] iason747:
There is a 32 bit rom for the Nexus 9...
[Nexus 9 General] tetebueno:
Things got worse overtime. I ended up installing Lineage OS 14. Works wonderfully and their installation tutorial is flawless. Can't paste a long but google "Lineage os flounder install".

Cheers.
[Nexus 9 General] hydromanbj:
Did you install 32bit version of Lineage OS 14?
[Nexus 9 General] humzaahmed155:
How unstable is that though? I want to try it, before I give up on this tablet for good and just sell it. F2FS and no encryption at least made it a lot more usable. But when you really get into productivity it starts to bottom out on RAM.
[Nexus 9 General] swaaye:
I've used Windows tablets with 2GB and they multitask incredibly better than any 2GB Android device I've used. I don't really understand what the deal is with Android being unable to keep a few mobile apps running at once. It's not a great multitasking OS anyway considering it's not really designed to have more than one app in view at once. And the quality of the app offerings for productivity is awful compared to Windows or Mac.
[Nexus 9 General] Nylo:
What? My N9/WiFi runs perfectly with LOS 14.1. I use it extensively for traveling in Europe, maps, email, surfing etc. and it's never failed me nor slowed down.

The only problem I'm having now is lineage just dropped 14.1 and there is no 15.1 for the N9/WiFi. Not sure what Im gonna do! I'm just hoping lOS will change their mind and start supporting N9/WiFi again.
[Nexus 9 General] madbat99:

[Xperia Z4/Z3+ Q&A, Help & Troubleshooting] ra3ul:
In the past couple of days for no reason my phone when ringing to receive a call will freeze and restart itself, hence, missing the call, I can see the caller ID but no luck answering, upon restarted the call will not be on the call log. It doesn't matter if phone is idle or using an app, any app. I've lost a couple of important calls today. Happens on both lines.

Has anybody had this happened? I'm thinking of a factory restore, but will accept any suggestions before doing so.

Also, when leaving a wi-fi connection, ie: driving away from home, it takes about 3 or 4 minutes lagging, and then it will function normally, what I have to do now is shut wifi off prior to leaving the house or the office, untill I get to a new spot, but sometimes I forget to turn it back on and my plan is running, any ideas?

Both issues I don´t think are related.

I'm on Android 5.02, build 28.0.A.8.251, haven´t done any rooting, just like it came out of the box.

Thank you in advance.
[Xperia Z4/Z3+ Q&A, Help & Troubleshooting] Bagne:
maybe you can try repair your phone through PC Companion,

mine got OTA update right after i got it out of the box, if yours was the same, maybe that's the cause.

Do you have GPS turned on? What apps are you using? I think this might be an app related issue..... I also hate losing data and customizations I've done and opt always to stay away from reseting etc....

Check Apps that use GPS and recent apps you've installed

You did factory reset or restore from pc? Also after that did you restore data with a program or pc companion or your started over?
[Xperia Z4/Z3+ Q&A, Help & Troubleshooting] ra3ul:
I did a Pc Companion full restore, followed guidelines step by step andI just started over.

Except for contacts, those I emailed myself and loaded them from there.

I guess it was worth itView attachment 3514686

I still have 15%, since 6:45 this morning, it's 10:15 I guess I could go a bit after midnight.

A lot of whatsapp (at least every 10 minutes) Mail, Facebook, Twitter, a couple of videos, some games.

This is what Xperia is supposed to be I guess

once you are rooted you will no longer be able to update even after flashing stock
[AT&T LG G4] mu3g:
I've read posts of people who have been able to do so by removing all their "su" apps (including Xposed and all its modules) --> performing an unroot & uninstall using SuperSU --> unblocking/enabling all the blocked/disabled apps using Debloater --> flashing the stock unrooted image for your version (10g in my case) using the LER method and then as a last step

hopefully

taking + installing the FOTA update.
