[Q] Extreme Lag In 3D Games - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hey guys.
When i run asphalt 8, i think I've got a Cortex A7 phone!!! loading takes much time, then graphics are awful, and there is a LOT, I MEAN LOT of lags in game.
I've tried everything, updated, remove bloatwares, everything, it's still the same.
my phone is D5803, and i don't use 4G-LTE, can i flash a D5833 to test it? will it harm the device?
thanks in advance

I installed A8 just to test what you are saying and I found that the game just plays smoothly and the load times are "normal" ... the phone even feels faster than my LG G Pad.
So, I really have no idea what's happening in your case.

I'm on Generic MENA firmware. latest .77 with root and bloatwares removed, and also locked bootloader, D5803
May i kindly know your configurations? even your customization number to download it via XperiFirm and flash it to see how it works?
By the way, my question remained unanswered, will it brick my device if i flash a D5833 firmware into my D5803?
tnx dude <3

It won't brick. Just to be on the safe side, you can exclude "baseband" in flashtool. That way the baseband of 5803 stays

Many say it has a frap limit of 30 on snapdragon devices.
i've tried playing it once, and it was laggy indeed.

4.2.2 update in UK??

When will the 4.2.2 update be released in the UK? Seems like it's been out for a while, yet my phone still hasn't found the update using either OTA or with PC Companion on my laptop.
We don't have the insight to say. Nobody has. And no crystal balls.
4.2.2 has been out for a few days only and is clearly rolling out across the piste.
Just wait patiently or use one of the other Generic ones if you're really that desperate. They're all basically the same apart from minor app differences.
I think Vodafone has released it someone on another forum updated his to 422 via Sony bridge on a Mac.
Never.... (joking)
Considering we were left out of the last few updates wouldn't surprise me if we are the last to get this one.
So I would guess a month

You have a UK unbranded device? Customisation number 1270-7689? Or some other UK device?
Not booting up my PC to find out if this is true or not, as other methods of checking are still showing 434 as the latest available for UK unbranded.
Edit: I see you edited your post. Yes, most are aware that Vodafone have updated

Mines was a VF UK handset upgrade - so branded to them. The phone itself didn't report any system/software upgrades, but as soon as I ran up PCC and plugged it in, PCC kicked off the upgrade.
Just use the Sony original Japanese update it doesn't change the language or anything and everything works out is the official Sony update and u just flash it with a flash tool no wipe of data or anything and u can easily root it with doomlords rooting method. It's a one click root.

Just change to a different generic customization. Some people seem to think that there is something special about UK firmware, but that isn't true at all (except that it seems to get updated last). All customizations contain the same baseband, kernel and core. The only difference is the bundled apps, build.prop and some overlays. I think 'Generic ES' is the best customization to change to. It contains all Sony apps (so you won't lose Video Unlimited or anything), of course it also contains all languages and it seems to get updates first.
Also, please stop asking when an update for a certain customization will be released. Nobody will be able to tell you, so it's completely useless to ask. There are ways enough to check the latest version for your customization. I have a list that I update daily or even multiple times a day, you can also create a browser bookmark to Sony's Firmware Update Server (see same thread) or you can use this web check: http://scavenger.ch/sonyupdate/.
Don't worry, it should come sometime this decade...we might even get the firmware update that everyone else has had for 2 months before 2017...wouldn't that be great?

Instead of waiting weeks/months/ages and complaining, just change to a different firmware customization like everyone else did. What are you scared of? There's always the possibility of changing back to 'Generic UK'.

That doesn't exist. In Japan, the Xperia Z was only available through the carrier NTT DoCoMo, which had a slightly different version with a different model number (SO-02E).
Check this list for the available customizations: [INFO] Latest firmware version per customization (region/branding). For the UK, I would recommend 'Generic ES'.

Downloading the 'Generic TW' FTF and flashing it with Flashtool, or changing your customization number in build.prop and updating with Sony PC Companion will give exactly the same result. 'Generic TW' is the only customization that has been updated for C6602. It also seems to get updates first each time. So I recommend to use that firmware.
I will sell my XZ and buy Galaxy S4 i think, its not about changing customization etc it shows how Sony treat UK customers...

Good luck with your (plastic) Galaxy S4 (with ugly *** TouchWiz) then. Hopefully Samsung will release updates faster to the UK
Do you really care so much about the 'Generic UK' customization? It's not like it contains any special features that can't be found in other customizations.

[Q] Flashable Roms for T-Mobile Xperia Z

So far I haven't seen a whole lot on this just that CM doesn't work right now. Does that mean roms like Paranoid Android and PAC Man won't work either??
Which type of roms will work?
Can anyone list a few of the best ones? Mine's coming through UPS on Wednesday and I wanna be prepared to do everything right away. Thanks!
I assume you mean the C6606 (the T-Mobile US Z).
If so, you can only flash stock based roms.
The bootloader cannot be unlocked on the C6606. Locked bootloader means no custom kernels, which in turn means no roms like PA, CM, PAC etc will work.
So, to answer your question, any rom that says it's for locked bootloader should work.

I'm opening flashtools. I click flash at the top, click flashmode, then I click that newest ftp and click flash. The window that says wait for flashtool pops up.I power off my phone..hold down the volume up button and enter the usb cable.

Volume up is fastboot. You don't want to be in fastboot mode.
You need to hold volume down and plug the USB cable in to enter flashmode to use flashtool.

I have the T-Mobile Sony Xperia Z. First I rooted with doomlords method. Then I installed dual recovery. I made a backup of my phone and installed the newest ftf file using flashtools. Then right after I flashed the rom that was posted above. It's working great so far and you keep lte and wifi. Hope that helps. It really is the best rom available to us at the moment because of the locked bootloader.

i have been researching this. it doesnt seem like there is going to be anyone who can unlock the bootloader. but there might be another way around it kind of like "mini loader" basically we will be able to flash aosp roms and custom kernals just no unlocked bootloader. pretty much jump thru hoops to do anything with c6606 t-mobile has Royally F'ed us... i really want someone to unlock that bootloader n RUB IT IN THEIR FACE! i dont know why they bothered with this... but theres got to be a way around this.... keep on hoping and lets see what happens i guess...
My xperia z should be arriving in the mail soon so I have a few questions. Just to confirm can the dual recovery foound here: http://forum.xda-developers.com/showthread.php?t=2261606 be installed on the c6606? Also are there any custom roms based on the t-mobile firmware because I would like to keep wifi calling. Thanks.

He meant Wifi Calling, which is only available on T-Mobile firmware. He just put a period in the wrong place.
Bump...any new Roms where we don't lose wi-fi calling?
None that Ive seen. Only ROMs for locked BL that are coming out are based on firmware made for the international market (4.2.2), none on T-Mobile (4.1.1).
The locked BL is really disappointing. Really limits the possibilities. I bought the Z on impulse and didnt research the Development situation on the Tmobile version before i bought, now im regretting it. I love the hardware and design, but will likely be trading it in by Christmas because of the lack of options for custom ROMs. Samsungs may be ugly as hell but you can hack the hell out of them. If HTC makes a phablet with the design of the One, Ill probably make the switch.
Back on topic, which LB ROM is most recommended and bug free? Any way to fix the poor wifi signal? Its chewing my battery like nobody's business.

Really disappointed with no custom Roms too might trade for another phone but not going to samsuck. Still have faith in what the devs here can do though.

I think you mean 2.245? I don't think we'll get it, I reckon we'll jump to the 2.250.
So you're on generic UK fw now? Is there much difference between that And the orange fw?
Also, re the post about rooting, I didn't root. I reckon the ftf I downloaded was faulty.

Ah yes, I meant the 2.245.
Yes, I am on the Generic UK fw now. There seems to be not much difference between it and Orange. (Orange one had a app called 'Orange core services or so).
The dailymotion and Deezer apps are missing (and whatsapp as well I think). Both fw did have all the google stuff. Also McAfee security comes with UK and the uk update to 1.257 brought Box installed as well.
out of topic: does the led notifications work for whatsapp (if your using it)? Seems it didnt work for me. Yet to test Viber.. n facebook.
Yep, orange core services, no idea what that was for,
As for whatsapp, sometimes the led works, sometimes not?! I'm currently on the Russian 245 as the ram management seems a little better, but still not great. I did root it when on the 257 so u could adjust the minfree values to make the ram management better, but it broke nfc.
Sticking with the 245 for now, not rooted, as its just a tad better than the 257 .

You may try that. You can set the color, rate of blinking and how you want to dismiss the LED notification.

After a restart the led started to work for the whatsapp and works for facebook and viber too.
Only started to use the phone fully since last night..so hard to say on ram usage etc. Seems bit slower at times than the Xp T though. Also I've started to notice instances of the screen being blurry at times. Have you seen that happen? When the phone it booted up, on lock screen the clock goes blurry and becomes sharp. Then on general usage there are times of blurriness.

C9603 vs. C6902 + Customization Version

Two days ago I purchased the Z1 from a local retailer (Tel Aviv, Israel), not realizing that it was the C6902.
The problem is that its customization version is 1278-3595_R1A (software: 1272-6084_13.1.G.2.257.)
I hadn't realized that .257 cannot be rooted prior to updating to it because the OS prompted me to shortly after I first booted it up, so I was hoping to downgrade to .535, root, and update it to 4.3, and then install a custom ROM.
However, I gather from the thread with all the FTF collections (here) that no customization versions of 1278-3595_R1A exists. Does this meant that I can neither root nor install a custom OS?
(why I figured this is important: here.)
In conclusion, I assume that C9603 will get better and quicker dev support, so should I return my current C9602 and purchase the C9603 online (Ebay) while I still can?
Bonus question: why the hell does the C6902 even exists if it's just the C6903 without the LTE? Better to have it and not use it -- no?
(Note: LTE, or any form of 4G networks, including WiMix, is and will be unavailable here in Israel for the foreseeable future - at least to the general public.)
Thank you.
Just noticed that the title should be "C6903 vs. C6902 + Customization Version". I mistakenly misplaced the two digits in C6903.
Even ordering online has some problems. but any replacement to your phone is better!

That's what I'm unsure of - hence the pilgrimage for confirmation of my as of yet unverified findings thus far.

You can flash ANY C6902 firmware.
I thought that there is something wrong preventing you from flashing another firmware ftf on your phone.

Ah, then it seems I misunderstood where the different variations stand in terms of compatibility. I'll be installing the IN version soon and see how things go.
Thank you for the clarification.

[Q] Downgrade from KK

Hello All,
After using using KK in my Z1 for a week, i am very pissed, i did not like it at all, it is very buggy, camera is very laggy, the **** restriction of SD Card with 3rd party apps, the separation of settings and notification in the notification bar, the phone get stuck several times which makes me to hard reset it, the phone get overheat very quickly while using the camera specially while taking pictures in a hot weather which finally will force stop the camera and show the message of high temp while trying to use the camera....
So I am thinking in taking my phone to customer service (but i have no time for that) or downgrading the phone to the last firmware before KK which was very good with no issues...
Please guide me on how to downgrade step by step with the name of tools needed.
P.S. I live in Middle East (Bahrain)
Thanks & Regards

Currently the phone is still new with me so i wanted to stick with the official firmwares until i get bored, then i will try the custom roms, Thanks for the link
Currently my build number is: 14.3.A.0.681 ( C6903 14.3.A.0.681 Generic MEA 1277-2882 in the thread)
So the one with JB should be the one before that build number which is: (C6903 14.2.A.1.136 Generic MEA 1277-2882_R2B in the thread)
That is right ? i should download 14.2.A.1.136 ?
Thanks

Yes the .136 is latest 4.3. Make sure to backup your internal storage if there is anything important on it as it'll be wiped

Yes. Using Stock FTFs with Flashtool do not void your Warranty. Unlock Bootloader does.
