its coming! Google Nexus 9

EagererBeaver

Got a software update notification (6.0.1) which surprised me as I thought that's what I was already on. Anyway, tried to install and have started getting the following error:

"there's an internal problem with your device. Contact your manufacture for details"

Happens every time I not and the UI is now slow as hell, with what could be, at best, described as horrendous frame rate drops.

Anyone else come across this?

Monthly Security updates for 6.0.1

Probably a corrupted update. If your bootloader is unlocked, you could flash the factory image and hopefully resolve it without wiping data.

If it is locked, you will need to wipe your device to be able to flash factory image. So backup your data and try a factory reset first.

EagererBeaver

Completely stock, have never touched it and download was OTA

Have tried to factory reset but it just keeps freezing when I get to the final "erase everything" button.

EagererBeaver

Have managed to get it reset through recovery but still getting the fecking message.

Is anyone else Nexus 9 gone dog slow?
Its fine playing games but using it for internet browsing, or Facebook, or any other app, and its so slow.

Half considering picking up the Pixel C. :mad:

Yeah in the last week or so mine has become almost unusable it's gone so slow and laggy.

Sorry for resurfaced thread! Anyone still with an operational N9 after 4 years?

Edit: Just ordered 32GB Black wifi model - Hope I don't regret it. For whatever future reasons!

Edit: I cancel my order with amazon, and placed one with google play. Which works out cheaper than amazon.

My tablet still functions but with a degraded battery, it freezes up (with static) when battery power is low.

Took advantage of Aliexpress 11/11.

Just ordered a battery for €15.14 of aliexpress (incl of shipping).

Also just tried the trick of disconnecting the battery, and now in the process of draining it completely, so to re-calibrate it.

Was not going to bother until I saw this reddit thread and got curious for what a replacement would cost.

The_B_Man

Mine is still goin strong, with SlimROM. Battery is still decent. It's slow enough when opening chrome (I think due to feck all RAM), but it's effectively a YouTube machine for the little one now, and works perfectly. Touch wood!

Is the back easy to get off to replace the battery? Any soldering involved?

I must check AccuBattery to see how healthy my battery is. Be good to have a backup just in case.

Our one still works - not amazing but still works. Battery poor at this point but we can live with that. Suprised its outlasted a lot of our devices!

No soldering just gently pry the back open with a plastic tool.

^^^ Expensive battery linked from that video!

The_B_Man

Just checked there. My battery health is 5500mAh so that's a loss of 1200mAh. Not too bad.

I saw online there was talk of soldering in new RAM modules, which I think would make a huge difference!!

Accubattery needs a few charging cycles (powered on) to get accurate readings, so if you only load the app in yesterday, give it a week or two.

Just put the app on my own today, so will see in a fortnight to a month, around the time my replacement should arrive hopefully.

Have you a link to the discussion on increase the ram on the device?
What i have checked on XDA, sound s like you end up with a brick or a device that can not utilize the extra ram due to kernel etc.

The_B_Man

Was most likely XDA I saw it.

I would have thought something like LineageOS wouldn't have a RAM limitation, considering it's built for so many devices with so many different combinations of RAM and CPU etc.
I'd have guessed that it'd search for RAM etc at boot, like a good old fashioned POST, and just used what was available. Unless its hardcoded into a closed source kernel or something.

Can you upgrade the RAM of an Android device?

You can't. Most smart phones are designed as a System-on-Chip; which means that the CPU, RAM, GPU, device controllers, etc are all in a single chip. Updating RAM in such system means replacing a whole lot of other stuffs. Not to mention that you probably would have a hard time finding a chip with different specification which fits perfectly into the hole that was left behind after you dismounted the chip; due to size restrictions, the components around the chip are designed to fit tightly into the available space.

Even if you did replace the RAM chip, the code to enable it is more than likely embed in property code on Vendor partition and maybe the kernel.

There is this thread on XDA but the author never got around to posting a guide or provide proof that he actually achieved it.

LineageOS and all other custom roms, need specific device builds (except outside of Treble enabled roms).

I would not recommend believing in Accubattery's health report's of your battery.

After 4 charges (while powered on), I'm getting estimate 5,622 mAh (84%), and after 4 years and usage patterns plus piss poor SOT. My battery health should be a lot worse than reported. Especially with the static freezes.

Also it is know that the app only reports estimates to around 90% of capacity. Two other devices, I have with much more charge cycles have been reporting that level. A newer device and a device with a replacement battery.

It due to the 10% the app can not read in the extremes (5% both ends).

How does a phone battery percentage display work?


After disconnecting+reconnecting the battery, and a re-calibration, as recommended on reddit, the device is no longer freezing with static. At least has not happened since I did that. But that is also report as a temporary solution and the problem may reappear.

.....

Battery arrived yesterday, reliable and genuine battery received.

Put it through a test yesterday, 12 Hours of use, 4 and half hours SOT, 20% Battery remaining.

Improvement from my degraded battery, that was lucky to last 5 hours and barely reach 2 Hours SOT.

Accubattery app will require a few charge cycles to get accurate estimated capacity. After 1 over night charge from 20%>> Health 93% ~~ 6,217 mAh

Thanks for that corkie,i was giving up on my nexus 9,but i might give that ali express batrery a go,showing at $18 but still a worthwhile deal.is it really as straight forward to change the battery as the guy in the video makes it look?

Yes it is that easy, 5 to 10 mins job.

But had a practice run to just disconnect battery before hand, so had an idea of the procedure.

All you need is the plastic pry tool, which I had from a previous battery purchase for my Kenzo.
Edit: - Tool not provided from aliexpress seller with battery.

Edit 2: - The device wouldn't turn on at first with new battery, until I connected it to a powerbank.

Did you order the same battery?
Looks like that particular seller, doesn't stock it anymore.
There is others that have it.

About 2 weeks for delivery, so doubt you have received it yet.

Tbh corkie i didnt bother,its the most annoying tablet i have ever owned,considering it was marketed as a premium tablet with a premium price.from the early stages there has been lag,apps randomly closing.i came.close a few times to bouncing it off the wall.i use it now mostly for just casting tunein radio. Thanks for the heads up about the battery anyway,appreciated

Same, flashed SlimRom and didn't bother installing Facebook and a few other apps which seem to chew up the battery

Works pretty well, it can be slow for a while after turning it on as it goes through the 'updates', but works fine when it's all updated.

I'd definitely recommend flashing SlimRom.
