In this overview I will not tell about characteristics, I will tell what to do if you like to stitch devices and that you receive having purchased Nexus 9. Also many councils can help also for other Android-tablets or even smartphones.

Nexus 9 — the overview from the geek, we stitch, we turn on the indicator of notifications, we increase operating time and many other things

What we will make in article
  • It is a little about picking and quality
  • Let's unblock the loader, we will set recovery, we will be updated to the latest version of Android, we will deliver to custom rom, we will set Gapps
  • We learn that it is possible to turn on the indicator under the screen
  • Let's increase operating time from 5 to 8-10 o'clock
  • Let's reduce charging time
  • Let's solve problems with random access memory.
  • We learn that standard Magic Cover is able




It is a little about picking, quality and highlights


Upon purchase the tablet very strongly sat in a box — at taking out it even began a little to understand. Be careful.
During tests it turned out that the standard battery charger at 1:5A, in attempt to connect the device which consumes more — is just cut down. For the first time I see it.

In general everything is collected well, there are no problems. An interesting part — the USB cable inverted.
In more detail about picking, etc. it is possible to read in other standard reviews.

Also I want to warn — LTE the version is not able to call, and here to send and accept Sms can. Calls cannot be included.
And still — the screen 4:3 i.e. if got used to watch video on the tablet — it is necessary to reconcile to black bands. At the same time it is very convenient to serfit the browser and to play the same HS — an ideal ratio of the parties for all tasks except video.
Even it is convenient to photo to look — a color rendition by the way good, but the tablet has zasveta which are noticeable only in the dark with black images or a dark background. It is not critical.

Updating and unblocking


It is better not to be updated through OTA — to you more than 5 updates which you will put in turn will arrive where that. It is far simpler to unblock the device at once, to download the last firmware and at once to stitch it — you will save several hours of time. Actually it is one of the reasons writing of article — I spent all day for updating process, and it was possible to keep within at 1 o'clock.

On process of an unblocking and installation of spendthrifts I will strongly not paint. I will make the main sources and recommendations. Especially, in sources there will always be much fresher data. And yes, you monitor what you swing — I have for example a LTE 32Gb version — some firmwares are compatible only to Wi-Fi the version.

All information is here — forum.xda-developers.com/nexus-9/general/index-nexus-9-development-t3070240

Let's assume you only purchased the device and tested it, you already decided that you will have non-standard ROM and a kernel. (here by the way it is important, I will describe further why)

  • At first unblocking. At the same time you will lose all data.
  • Further I recommend to set a fresh image of system — you will stitch developers.google.com/android/nexus/images Through the built-in script of FlashAll all at once that is necessary.
  • After they are TWRP
  • After that you can download any ROM, I for example use The Pure Nexus Project
  • To set a kernel — I advise Simple Stream
  • We take Gapps to the 64th bit version (it important!) — opengapps.org
  • After updates through recovery surely we clean manually caches — otherwise at start receive errors from a half of the installed programs


The indicator of notifications under the screen — or why we delivered to Custom ROM


I got used on Nexus 4 that at receipt of the notification under the screen the indicator burns. And here it from a box does not work. It flickers only if you put the battery in 0 and connected charging. At the started system it is not even in settings.

It looks here so —

It absolutely white — not RGB. But also it quite is enough.
In non-standard firmwares it is unblocked and executes the functions.

We increase operating time from 5 to 8-10 o'clock


I was a little surprised when using 2 days, I noticed that the tablet sits down already in 5 business hours of the screen.
The reason in very big warming up of the processor, and also in Chrome!

And, it is possible to switch off the preset Chrome and to set from Chrome Beta market — the problem is solved completely. That is Chrome Beta works quicker and does not heat the tablet — any magic.

Also you can configure the custom kernel so that governor CPU was not Interactive, but ondemand. It is also possible to lower frequency to necessary for you. However the solution in lame most strongly increased operating time.

Today I received already here such results — I spent 50% of the accumulator for 4 hour of work. Earlier at 4kh business hours of the screen, I had 10% of the accumulator.

At the same time Hearthstone was a little started that too strongly influences. But the most important — the tablet does not burn a hand in chrome any more.
In a network where that was seen by a screenshot — the user in general delivered himself the simplest browser and achieved 11 business hours.

Time of charging and indication


Initially the tablet is charged on 500 mA from the computer. And 1.5 A through a standard battery charger. And at connection of more powerful — it will be loaded all the same 1.5 A — it is connected with restriction in a kernel. There are 4 hours of charging that long enough.

And here the non-standard kernel allows to charge the tablet with 2A charging. What quite reduces time till 3 o'clock. And as the bonus — the tablet pulls from USB 3.0 900 mA now.

There is a problem with indication on some combinations of firmwares/kernels. It is observed in the form of 3747% of the accumulator (at the same time everything is loaded and discharged)
Also even at normal indication charging can sometimes stop for 50-80% (at the same time all 100% are loaded) — reset solves a problem.

I think creators of spendthrifts and kernels all these defects will solve soon.

The interesting part on performance — in spite of the fact that it left a year ago — it bypasses even innovations

For example, in geekbench it even bypasses Google Pixel C

Random access memory — a big problem


When I only began to use I noticed that having loaded couple of tabs in chrome — all other applications began to fall. Actually first of all chrome changes for a beta, as well as with a case with the battery — it helps also with memory.

And also I wrote about a kernel above — in it ZRAM costs on 500Mb that just solves problems with memory.
At the same time when testing noticed that from UKSM there is no sense, but at the same time logs from it noticeable — it is better not to include it.

At 64 bits of the application guzzle not strongly more — and here system processes and OS are surprisingly one many more.

Magic Cover


I purchased the tablet with Magic Cover at once, I was strongly lucky that it was in shop.

It is such cell-like pad which can be attached to back or front part of the tablet. Keeps on magnets around a metal frame of the tablet.
Magnets do not hold the tablet suspended, also at a turning it is possible to drop a cover — more carefully.

From interesting features — at bending back or a bending of a corner — the camera turns on. And it is the most convenient to bend it in inside, then it does not prevent shooting

Quite good video overview of a cover.

It is soiled by the way quickly enough. One party at it soft, other a little "rubberized".

More carefully with a cover — it spoils back part of the tablet. On dark model it is not strongly noticeable (though I noticed) And here on light receive clouds behind

Results


The good fast tablet, copes with all tasks assigned to it. Quickly works, very thin — here the cover from back part of the tablet helps even to hold it in hand more conveniently. There is a backlog on the future — though memory pumped up — 3 Gb RAM would be better. In this plan in fact Pixel C is more convenient, however it is slightly more in dimensions.

I will add to this article still some moments which still I will find. Actually article was written just for those who decide to purchase this tablet now — it is possible to solve on points a number of problems at once and to see all "reefs", and a lot of boring reviews on all network are most often useless.
