[Windows Phone 7 General] sano4ever:
Windows Phone has been dead for a good year now, and Microsoft co-founder Bill Gates has decided it’s also time to move on. In an interview with Fox News Sunday, Gates reveals he’s now using an Android phone. While Gates doesn’t reveal the exact model, he does note that it has “a lot of Microsoft software” on it, which could suggest it’s a special Microsoft Edition Samsung Galaxy S8 handset with bundled software.

Microsoft started selling the Samsung Galaxy S8 handset in its retail stores earlier this year, and it includes apps like Office, OneDrive, Cortana, and Outlook. Any Android phone also supports these apps, but Microsoft’s customized S8 does suggest the company might continue to offer this for other Android devices in the future.

While Gates is switching to Android, he’s still not interested in an iPhone. Gates famously banned iPhones and iPods at home in the past, but he does admit that Steve Jobs was a “genius” in the Fox interview. Gates is still using Windows-based PCs, but he’s still not switching over to an iPhone, despite the Steve Jobs praise.
[Xperia Tablet Z Q&A, Help & Troubleshooting] purt51:
For some time now my Xperia Tablet Z has been feeling a bit slow to load web pages. After some performance profiling I came to the conclusion that the problem is its Javascript performance. Many web sites nowadays use large amounts of Javascript to build up their content and this is reflected poorly on browser processing times. For example, on a Finnish news site www.yle.fi the script processing on my Xperia Tablet Z usually takes something like 15-20 seconds whereas on my Xperia Z5 Compact it seems to take roughly half that time.

To get some comparable figures I ran some online Javascript benchmarks and here are the results:

sunspider-0.9.1 (lower times are better) :

Xperia Tablet Z ~ 2400 - 2700 ms

Xperia Z5 Compact ~ 1000 - 1400 ms

JetStream 1.1 (higher scores are better) :

Xperia Tablet Z ~ 14

Xperia Z5 Compact ~ 27 - 36

I did try these benchmarks on both Chrome and Firefox and there is no significant difference between the two. I'm currently running crDroidAndroid 3.7.

I'm wondering if these performance figures are in the right ballpark and therefore it would be nice to have some results from other owners of Xperia Tablet Z for comparison. In addition to the benchmark results, please include information on which ROM / kernel you are currently running. Thanks in advance!
[Xperia Tablet Z Q&A, Help & Troubleshooting] Rootk1t:
The hardware in tablet remains the same all the time, while workload increase constantly.

So there should be no surprise, that it takes long for tablet to process information.

On RR 5.8.4 with built-in kernel, i got 2477ms in SunSpider | 15.238 in JetStream in chrome-based browser, so your results are in the same ballpark as mine.

Working:

WIFI, BT, sensors, battery, USB.

does not work:

Cameras, LTE, OTG.

The Date, Cache partition is only supported in the EXT4 format.

The system is 32 bits, which means that the GAPPS set the arm version, not arm64!

You need to reformat the data, Cache partition to remove encryption and change the format to ext4!

No GAPPS included.

Fix termal throtling

HACK slip Lp0. Unfortunately, the dream is not complete. After waking up, the battery charge drops. The indication of the charge value of the battery smoothly comes to the actual state. Battery discharge is about 3% per hour.

ROM Version-1912 Download

Updated the kernel 23-12-17:

- fixed the battery level during sleep.

- fixed the NFC.

Updated the kernel 31-12-18:

[Nexus 9 Android Development] ItAintMee:
hey guys, is this ROM getting greater graphics performance compared to Oreo ROMs? currently have my flounder on RR V6.0 a and its decent, but the tablet heats up like crazy. would this be a better ROM choice than what I'm currently on? how would I go about installing this after having Oreo installed?
[Nexus 9 Android Development] swaaye:
It has a somewhat newer graphics driver and supports (rather useless) Vulkan, but I had problems with games crashing. I don't know if he got that fixed.

Nothing will stop the tablet from heating up and throttling. Undervolting helps a bit though. It will throttle less severely. The problem is it's too hot of a SoC to run at full output in a fanless tablet for an extended period of time. You can also try a tuning app that forces the CPU to run at a lower speed. Say 1.8 GHz (this also runs at a lower voltage, so the heat is considerably reduced). And then the GPU won't throttle as much.
[Nexus 9 Android Development] ItAintMee:
thanks for the response :good: how would I go back to this ROM from Resurrection Remix? would I have to flash older firmware first? is there anywhere I could find some instructions? I bought this tab mainly to emulate

Vartom, thank you for all the work you have done on this ROM, certainly is not low hanging fruit.

I am wondering if this is worth it for PSP emulation purposes. If OpenGL is slower on 32 bit then it might not make sense. I am hoping to increase processing power with Vulkan for ppspp PSP emulator and maybe other games.
[Nexus 9 Android Development] Nex5x:
32 bit Vulkan vs 64 bit OpenGL ES

To clarify and broaden, I am wondering like previous posters if this ROM helps with performance or is useful more from a perspective of being ABLE to run Vulkan. Thanks.

Can I just use this vendor ?
[Nexus 9 Android Development] Monfro:
You made really a wonderful work porting this kernel and enabling Cuda and Vulkan.

I am sure that with time everything will be sorted out.

Now that Nexus 9 is becoming cheaper on second hand market I think that new devs will buy and play with it.

I have seen also for other devices a "second wave" devs that obtained great results.

Don't give up!

You already made an incredible work arriving at this point

How is smoothness/ lag compared to other custom ROMs? I'm currently on slimrom and it's acceptable. Any advice would help.
[Nexus 9 Android Development] didnt1able:
No room will make magic happen. The N9 will always be a dumpster fire. BUT big BUT here. If this pans out, vulkan will make a night and day difference for gaming (to an extent). As far as smoothness is concerned the device will still have sub-par navigation of the UI. 2 gigs of RAM and dual core is just not cut for today's use cases with having multiple apps open and swapping and so forth. But for games, focusing resources to one task, the Nexus 9 does well. The second a ZIP is made available I will be on that in moments.
[Nexus 9 Android Development] swaaye:
I think it's mostly Android at fault. 4GB would undoubtedly help, and maybe also faster storage. But Surface 4 is a dual core machine, and 2GB Windows tablets adeptly multitask. Android is just a toy OS compared to Windows.

Sure, 2GB isn't ideal. But the Kangaroo PC that I've been using for over a year is great for what it is, and I've liked my previous 2GB Windows tablets. They are more pleasant to use than the typical cheap hard drive equipped notebook! I certainly would want 4GB+ in any new device though.
[Nexus 9 Android Development] didnt1able:
I have some Asus transformer thing it's a 2gb ram system quad core and some pretty slow flash storage. It's pretty bad. What is kangaroo PC? Something similar or does it have the option for SSD storage? Personally I don't find a speed difference between slow flash storage and a decent harddrive. Mainly because the slow controller that's used. But if that thing has an actual SSD with a decent controller that could make a major difference because of the speed of your swap(page file).
[Nexus 9 Android Development] swaaye:
Kangaroo PC is a mini PC that's the size of a deck of cards. Basically a tablet without a screen. The storage is pretty fast. I think it's just EMMC. EMMC doesn't have to be awful.

But yeah if the EMMC chip is really slow, that will ruin anything. I can definitely see ASUS doing that. That's often a problem with Android tablets as well. I have a horrifically slow ASUS EeePad. And their other Transformers with Android had big problems with EMMC slowdown/degradation. That was a thing with a lot of tablets and phones back then.

I flashed this build on my Nexus 9 and it's up and running. But I am having a problem with screen rotation. It seems to be +90 degrees off. So it rotates +90 degrees clockwise to landscape when I hold it portrait.

Overall though it seems very fast and functional. I used OpenGapps Pico. Played a race of Carmageddon as well and that was perfectly smooth as it should be.

USB OTG doesn't work but that's noted.

hi [MENTION=6556709]Vartom[/MENTION]

Am not a N9 user at all. Am looking for some Vulkan API workaround and someone point me to your thread.

We try to maintain some sony Xperia devices msm8994 (qcom) based and this soc is 32bits, so do not have vulkan support.

I looked at https://github.com/vartom/android_d...mmit/33c04e4e606d12ce8dfd59c8ff9352edbc01d1e6 but do not really understand how your implementation works.

Does NVIDIA updated your 3d tegra BLOBs or are you using some SW implementation?

Can you, please, point me to some of your changes &| links about Vulkan support for 32bits ARMv7 socs?

Thanks in advance.

I flashed the rom and gapps but when I try to boot up it shows the word "google" when it first starts then changes to "android" then just sits there. The word is animated in that the letters turn flow in different brightness so it's technically locked up. Any idea what is wrong? Also I downloaded the ROM Version-1912 Download link for the rom that's the right one? I wiped everything cept internal storage when I reformatted and changed the data format the ext4 like in the instructions.
