[Xperia Z General] TorN-d-:
I'd have to disagree with you on almost all of the things you just said :P

Speed - 6.5/10 The device actually does stutter because of the old and "slow"(by today's standards) CPU. But most of all, bad coding and bad software is pissing me off, for example recent apps with smallapps usually takes about 2-5 seconds just to show after pressing the button. I'd say speed is OK, the Z won't piss you off, most of the time :P but compared to lets say nexus 5 its slow as a ****ing snail.

Camera - 8/10 I really have no idea how can you rate this camera so low. What were your criteria really for grading the camera?

Yes, it's not on par with current flagships, but if you go back to 2013, it was right there with back-then flagships, except for low-light photos.

BTW, you probably got a bad phone, since i never got the overheating message, nor did my friends that have/had the Z.

Screen - 5/10 Out of all the things that are actually good, for the only thing that is really bad on the Z, you say its good.... Seems to me you never held more than a few serious phones in your life but OK...

Screen is OK, but lack of contrast, oversaturated screen which needs to be adjusted so it isnt all yellow on white background, and those ****ing viewing angles.... the screen is just OK, nothing less, nothing more.

i dont even agree with build quality, because it seems to be different for different batches of phones. My phone for example is perfect for almost 2 years now, and material usage is cool for me, because it would be fatter with metal edges(like the Z1).
[Xperia Z General] TorN-d-:
OK since i took the time reading you rubbish kilometer post i gotta answer.

i never saw noticable chromatic abberation.

you do know how proper HDR mode works? it pieces together 2 photos? ofcourse you are gonna see ghosting if you move the ****ing phone while shooting.

BTW blurry day shots are because of superior mode yet again, because it automatically activates HDR if there is high contrast on the picture.

check some tests that professionals did. the camera is GOOD, except low light. colors are oversaturated on superior mode. But 90% of users and reviewers are probably crazy, yeah, the camera on Z is **** :)

the OP asked if it was better than his previous Z ultra. it is miles better.
[Xperia Z General] Okluzhion:
I'm selling my Z soon. If I had known I'd have so many problems, I'd never have bough it. I changed USB cover flap 2 times already, changed back cover because it cracked (that was my fault, though, didn't have a case and dropped it on the floor, but still), had to peel off the ASF because it scratched pretty quickly and bought a screen protector to replace it. To top it off, my camera has started to get more and more dead pixels, and it's very noticeable. The quality of photos has gone from good to horrible. It's like I'm not even using what used to be a flagship. Front facing camera is pretty bad as well. Battery life is poor, but it's an old chipset, so not much can be done in that department. Screen is okay, I don't really care about viewing angles. Multitasking is fine, too. A bit slow compared to the new phones, but still fast enough (I don't play any heavy games on phone). Typing is for some reason a nightmare at times. I type more accurately on my old Xperia Arc and my boyfriend's Meizu M1 Note than on XZ.

Xperia Z feels like a heavy test subject for latter Z series. Personally, if I had to choose a phone from this series, it would definitely be Z2. I liked its design the best. But for now, I'm staying away from Sony products. Not only because they have disappointed me again (Xperia Arc had build quality issues to begin with), but are also out of my price range now.

Even though I liked Z in the beginning, I somewhat regret spending so much money on it.

[Xperia Z General] cocagenda2:
totaly agree with u about the camera taking good pics outside when its brite and bad pics in low lite condition. i had xperia Z for about a year, now my mother has it still a good phone but those flaps are bad made and yea i also forgot to say that it has very very i mean very bad quality speaker LOL did they make joke with us back then in 2013...my first thing when i got it was, i rooted the phone and flashed sound mod lol eveything else was fine i think.now im using Z2 for more then a year and im so satisfied with the phone that my next will be from Sony again maybe Z5 or whatever it comes. :highfive:

We all know that the 3 weakest parts of the HTC Universal are the USB port, the screen hinge, and the screen itself. A friend lent me another BT headset to try, and I crammed it into the belt carrier with my phone. Result: cracked screen.

Sent it to Pocket PC Techs (the i-Mate-authorized repair center, by the way) for repair ($250). They repaired it the day they got it and I received it back the day before their tracking said I would, good as new. Not only did they replace the LCD, but they also adjusted and tightened the swivel.

My impression is that they're a first-rate outfit--which isn't always the case with a manufacturer-authorized repair center, based on my experience. Hope you never have to find out, but just in case.... Cheers,

Important Note:: This kernel is based on the LZD22D kernel source code (say "thanks" to Google for not releasing the source code yet). I had to make some changes to emulate the changes they have made to the backlight brightness but otherwise the source seems to be compatible enough to work well. When Google updates the source, I'll merge it and release that version.

The following versions with changelog are available:

* boot-tetra-LCA43-r7.img

Enable ZRAM to increase the available virtual memory space

Enable KSMa

Configure the interactive cpufreq governor better

Add bfq io scheduler (although it's not being used any more)

Fix cfq to be more performant for SSDs

Modify the Android Low Memory Killer to work correctly with swap enabled

Note: this combined with enable zram seems to fix one of the major 5.1 battery drains for me. Please let me know if that's not the case for you.

Disable modules (free up more kernel memory)

Disable extra debugging (free up more kernel memory)

Disable NFS (fre up more kernel memory)

Enabled compiler optimizations to speed up the kernel (uses more memory)

Disable "adaptive low memory killer" (seems like the stock kernel is killing too many processes, this may help that)

Updated to Linux 3.10.86

Enable all 4 cores

Installation:

* Reboot to fastboot and then

fastboot flash boot boot-tetra-LCA43-r<whatever>.img

.

Warnings:

* This probably breaks your ability to accept OTA updates.

* github : the repos you need are all explained there along with how to compile it

[Sony Smartwatch 3] anees167:
wanted to ask, if you are using this kernel... how do you update your watch to the latest version?? and do you encounter any issues??
[Sony Smartwatch 3] crpalmer:
I definitely use the kernel. I actually completely stopped using my watch when 5.1 came out and there wasn't kernel source to work from to fix the battery problem. It was just more annoying with that problem than having the phone was worth. Now I'm loving it again.

You should be able to back-up and restore using twrp and just doing fastboot boot twpr.*.img to run it without modifying your recovery partition.

Prior to this last release, I had system dumps I made myself of the first release. I just put them back. Unfortunately, I just found out on this release that you can't downgrade (I couldn't boot the old images). In case of emergencies like that, Sony PC Companion (?) lets you reflash their latest image which is what I did to fix it last time.
[Sony Smartwatch 3] anees167:
thanks for the reply... really tempted into installing the kernel... will let you know once i have downloaded the kernel...thanks
[Sony Smartwatch 3] DarkRazorZ:
Just flashed the kernel now, watch is running fine without issue. Thanks for your work! Quick question: I'd like to be able to use WiFi in apps like Chrome, Twitter, etc. (sideloaded) but I can only do so if I disconnect the watch from my phone. Is this controlled by the kernel and if so is it possible to have WiFi working in these apps? I know WiFi will run in smartwatch apps without having to disconnect from the phone, so I'm not sure what the issue is.

Alternatively, is there way to let these apps have access to the phone's data via bluetooth?
[Sony Smartwatch 3] crpalmer:
I've never tried chrome or twitter.

Whether or not WiFi is enabled is not a kernel decision though. That is all user-space (aka Wear aka closed source that I can't do much of anything with).
[Sony Smartwatch 3] lekofraggle:
So, WiFi is limited on wear. As deployed, there is no WiFi access to user apps. System apps do get WiFi access. However, elevating a web browser or Twitter app to system status could be a huge security risk.

I do not think this limit is in the kernel, I think it is a permission set somewhere.

So, as of now there are three options.

1)Put the watch in airplane mode, then connect to WiFi. For some reason this works and is more secure than elevating permissions for every app you use to go online.

2) Put any app you want to use online in /system/app or /system/priv-app. Know that space is limited, and this could be a security risk (You need root for this too).

3) Use (or make) a specific app designed to take advantage of WiFi on wear as a user app (so Google must let you define the permission in the manifest) such as wear internet browser. Or, use (or create) a specific wear app that takes advantage of the phones data with a host app and bluetooth. Note that a persistent connection to the phone may use more power, but so will keeping the screen on to surf the web.

So, some apps are probably worth dumping in a system folder. Es File Explorer comes to mind. Others, not so much if you ask me.
[Sony Smartwatch 3] greenbat:
Can someone please benchmark the watch with stock rom and this custom rom. It would be interesting if scores are much higher with 4 cores enabled.

Please use vfp benchmark for android wear.

Thanx!
[Sony Smartwatch 3] DarkRazorZ:
Damn, I'm really hoping there's an easy solution to take advantage of data over Bluetooth for sideloaded apps. Also, just want to say that I have not charged my watch since flashing your kernel and I'm still at 53% right now, this is the best battery life I've had since buying my watch, so I think you may be on to something!
[Sony Smartwatch 3] mickael91210:
Hello and thanks for your work...

I never modify my watch and I want to install your modified kernel. I hope it will really fix my battery drain (As soon as my phone is disconnected my battery decreases extremely quickly if i don't see that and if I don't use plane mode...)

So is it possible to have the full procedure (from stock) to install new kernel or a link? As same to come back to stock?

Thanks a lot.
[Sony Smartwatch 3] RJASSI21:
Im thinking this kernel was successfully installed as u can see where most of my drain was before installing the kernel and performance improvement it has thanks

Sure thing!

Pre-flash (stock LCA43):

Single Thread SP: 2.291 GLFOPS

Single Thread DP: 1.155 GLFOPS

Multi Thread SP: 4.792 GLFOPS

Multi Thread DP: 2.331 GLFOPS

Post-Flash (this kernel):

Single Thread SP: 2.306 GLFOPS

Single Thread DP: 1.154 GLFOPS

Multi Thread SP: 9.185 GLFOPS

Multi Thread DP: 3.041 GLFOPS

The multithread results certainly show an improvement. Ill be happy so long as the battery doesn't tank mid day.....
[Sony Smartwatch 3] RJASSI21:
Im getting more tempted to move chrome into the system since TWRP has a built in file manager it is possible I managed to install an apk using 3 apps:

1.)Chrome on Wear

2.)Superbeam

3.)Es File Explorer on Wear

What I did is used Superbeam on my smartphone to send the apk to the wear device then I disconnected my smartwatch from my smartphone and copied the ip address for the apk into chrome on the Wear device then allowed it to download the apk. Once it had downloaded I used Es File Explorer on Wear to check if it was successful and successful it was. Then I booted the wear device into TWRP and moved/copied the apk into data/app (I used TWRP since Es File Explorer wasnt showing the directory) then I chmoded the apk to 0644 and surprisingly when I rebooted it worked so im gonna try various apps using this method and consider moving chrome into system to see if that allows wifi while connected via blutooth.
[Sony Smartwatch 3] greenbat:
Very nice improvement :)

Do you notice a smoother watch experience? And any noticable battery use change?
[Sony Smartwatch 3] Divine_Madcat:
Truth be told, i never really had a performance complaint (especially compared to the Moto 360... what a beautiful slug), but it certainly doesn't feel like it is lagging at all. Ill keep an eye on it over the day, and report back when i have a better feeling for it..
[Sony Smartwatch 3] matejdro:
Is removal of pixelated ambient mode included in this version or do we need to wait for source drop?
[Sony Smartwatch 3] lekofraggle:
Why not just use es file explorer?

Move it into the system folder on the watch.

Install it on the phone.

Find the apk in essence file explorer on the phone

Long click,

Send to device

Open es file explorer on the watch

Send apk to watch from phone

Accept the file transfer on the watch.

Go into tools in es file explorer on the watch

Click on manage apps

Navigate to the folder where you saved the apk

Install.

Good luck.
[Sony Smartwatch 3] RJASSI21:
I cant find the manage apps tool I managed to send the apk but I really cant see the manage apps tool and the acctual tool button on the homepage just throws up a bunch of ads with other apps to install and if I navigate to the folder it cant install because android wear has no package installer
[Sony Smartwatch 3] lekofraggle:
Try this...

In Es File explorer, go to the tools section.

Click on the root explorer toggle

Then click on the text for root

It will pop up a menu

Click one click install

Find your app and install it
[Sony Smartwatch 3] karl0ss:
great work on this kernel, thanks for getting it working on the latest build :)
[Sony Smartwatch 3] RJASSI21:
That menu pops up on my phone but not on my watch on the watch when I press root Explorer it does nothing
[Sony Smartwatch 3] lupick:
bootloader need to be unlocked in order to flash this kernel?
[Sony Smartwatch 3] DarkRazorZ:
I imagine so. Unlocking your bootloader is a very simple process though.
[Sony Smartwatch 3] mickael91210:
Hello,

Now that some days are passed... Can you confirm that with this kernel the battery drain is really gone?

Thanks

Are you using any special setting? My device can Last 1day

[Sony Smartwatch 3] crpalmer:
No. I leave all settings as they are set after a factory reset.
[Sony Smartwatch 3] lekofraggle:
With a little work, you can flash this kernel without unlocking the boot loader. What you need to do is...

Root your watch

Adb install es file explorer and flashify (you can download es file explorer from the web. I am not sure about flashify. I pulled it from my tablet).

Push the kernel to your ad card.

Open flashify and back up your current kernel.

Open es file explorer and find the kernel.

Click on it and open with flashify.

Select okay to flash to boot.

Enjoy.
[Sony Smartwatch 3] DarkRazorZ:
Battery is still doing well, nearing 24 hours with about 68% left, all my settings are enabled (WiFi, GPS, etc.). I think it may be safe to say this kernel fixes the major battery bugs.
[Sony Smartwatch 3] gscollier:
No

---------- Post added at 04:48 PM ---------- Previous post was at 04:47 PM ----------

Way too complex. Root not needed. Just flash in fastboot as per OP. No offense intended :)
[Sony Smartwatch 3] kalousek:
no root, unlock bootloader or custom recovery ?

HI,

so for installation I dont need root, unlock bootloader or custom recovery ? and if I will want to come back into stock (with OTA and full warrranty) is there any option to go without a trace of custom kernel ?

Can you put here some detail tutorial for smartwatch nobs ? :p How to flash this kernel and how to back to 100% stock.

Thanks guys :)
[Sony Smartwatch 3] piggarello:
tryng to flas i had this:

target reported max download size of 425721856 bytes

error: cannot load 'boot-tetra-LCA43-r7.img': No error

i made something wrong?

thanks

F:\OneDrive\Z3\motog>pause

[Sony Smartwatch 3] DarkRazorZ:
Did you flash it or try to boot it?

Should be "fastboot flash boot boot-tetra-LCA43-r7.img"
[Sony Smartwatch 3] piggarello:
ctrl-c cltr-v command on post 1.....

this is the batch...

echo on

fastboot flash boot boot-tetra-LCA43-r7.img

[Sony Smartwatch 3] gscollier:
All your assumptions are correct. As for getting back to stock apparently PC Companion will get you back to "official". Haven't looked into that since applying this kernel over 12hrs ago I still have 80% battery left. So assuming it stays that way ~40% per day. Best I've seen since getting the watch 6 or 7 weeks ago.

Some hints, in sequence:

On the watch, turn on developer options in settings/about device then click on build number 7 times.

In developer options turn on ADB debugging

Connect watch to PC and use "adb reboot bootloader" - you may need to setup an adb folder, plenty of resources to help you with this.

Once in bootloader use the command in OP "fastboot flash boot boot-tetra-LCA43-r<whatever>.img". You can keep the same command window open that you used from the adb part and type in the command there.

Then "fastboot reboot" and done.

No messing with su, unlocking etc. The only concern might be void warranty, flashing a custom kernel will void it but if PC Companion can reflash a stock then you are good to go. No knox nonsense as per Samsung, not sure if this sort of hacking is logged somewhere on a Sony device. FWIW I void my warranty on all my devices the moment I get them :)

Bad download of the .img file? How are you getting into bootloader mode?
[Sony Smartwatch 3] kalousek:
Thank you very much. I will try it and will write here my experience with this kernel. :)
[Sony Smartwatch 3] gscollier:
Good luck. Feel free to PM me if you need further info.

Mr Palmer, kudos to you. Very happy so far with the kernel, early days yet tho :)
[Sony Smartwatch 3] piggarello:
Ok...

long press power...then 2 press to enter menu that leed to fastboot...

i've downloaded the file twice...is 5,8MB so if the limit is 425721856 bytes software is right...??

EDIT: ok redopwnloade for third time it goes...thank you.....

---------- Post added at 12:06 PM ---------- Previous post was at 11:44 AM ----------

how can i see if i'm using ths kernel???
[Sony Smartwatch 3] kalousek:
Hi,

So i try to flash kernel, but it writes following error (I think, that i need unlock bootloader)

c:\>fastboot flash boot boot-tetra-LCA43-r7.img

target reported max download size of 425721856 bytes

sending 'boot' (5754 KB)...

OKAY [ 0.254s]

writing 'boot'...

FAILED (remote: Device locked)

finished. total time: 0.258s
[Sony Smartwatch 3] crpalmer:
adb shell cat /proc/version

If it is running my kernel it will say (crpalmer@compile) in the string.
[Sony Smartwatch 3] gscollier:
Possibly bad download, note that [MENTION=737936]piggarello[/MENTION] had to downloaded 3 times. I used a PC, first download was fine.
[Sony Smartwatch 3] kalousek:
I tried it at least 5 times. Same error. Device locked. Are you sure that, I do not need to unlock bootloader ?

Thanks.
[Sony Smartwatch 3] gscollier:
I certainly did not unlock bootloader and no others have mentioned it.
[Sony Smartwatch 3] kalousek:
Hmm.. you don't have any idea? :D I downloaded this image 4x time and situation is same. It lookes that problem is in sending img to device.
[Sony Smartwatch 3] matejdro:
gscollier are you absolutely sure you did not unlock it? Did you get watch second hand? If yes maybe previous owner unlocked it.

Whole point of locked bootloader is that NOTHING CAN BE FLASHED except kernels and ROMs signed by Sony.
[Sony Smartwatch 3] gscollier:
It is not unlocked but I've just checked my watch with adb shell cat /proc/version and it seems that the kernel did not go on (no crpalmer@compile in the string).

I tried flashing again and I do get a failure. I probably saw the OKAY message and did not read all the fastboot output. So in effect I do not have this kernel but have noticed a marked improvement in battery life. What I did do yesterday is factory reset after "flashing", perhaps that has helped.

Sorry if I have misled anyone, had assumed LB was OK as was not mentioned in the OP. The upside for me is that after factory reset things are looking very good. Only been 24 hours tho.

---------- Post added at 08:39 AM ---------- Previous post was at 08:38 AM ----------

Please see above. It seems you are correct. :(

Maybe try factory reset, I at least am getting very good battery life now.
[Sony Smartwatch 3] kalousek:
That´s ok. :) Is there a way to relock bootloader without any trace ? ( 100% stock ? )
[Sony Smartwatch 3] gscollier:
Don't know but I recommend trying a factory reset first. Since I am not running this kernel and battery life is definitely better it is the only thing I did yesterday that might explain the improvement. Factory reset its not too painful after after a few times :)
[Sony Smartwatch 3] kalousek:
I did a factory reset after wear 1.3. update. And it fix 99% battery problems. (After 4 days i got battery drain in theater mode at night)
