Redraws in Lollipop? Hmmm, never experienced any. I play Asphalt 8, Real Racing, Darkness Reborn with the graphics in full, watch movies, youtube, etc., never experienced redraws. Only thing I don't like with Lollipop is it doesn't have a fully blacked out ROM yet that doesn't require unlocking of the bootloader, hence I downgraded to Kitkat 4.4.4 for now.
[Xperia Z1 General] amnher:
Its not the performance. Look at this post Memory Problem

I don't have lags but the problem is the leak. I can't keep my apps open on the background especially when the phone has been running already for more than 8 hours(meaning no restart)... I need to constantly reboot my phone to maintain multitask. Otherwise apps on the background keeps on restarting (after several hours of use) itself when the phone has not yet rebooted for a long period of hours. You can notice it when you go to Settings>Apps>Running... You can see most of the apps are restarting (After several hours) . I have a screenshot before and I'll try to paste it here. But this has been the problem since lollipop and many users experience this leak. Not only on xperias but others as well for those who are on 5.0.X... Thats why in my case that I use VPN + online game makes the game or the VPN on the background close by itself(Randomly all of a sudden) if my phone has not been rebooted for several hours already. By the way in my case I have only stock apps + VPN and one game installed.
[Xperia Z1 General] Deathschythe33:
Hhhmmmm... really weird. Not that I'm saying your just making it up, but I haven't experienced these issues. I mean, in Real Racing, if I keep using the same car on multiple races, I will eventually need to have the car serviced. And at times, Service can take 4-5 hours specially if I keep banging against other cars - lol - road rage / race track rage. So I would go to other games, like Asphalt or Darkness Reborn. Then once I get a notification that my car service is complete, back to the game through the recent pane and I don't experience this restarting. I get back to where I left. So I guess... lucky me I am not having the issues your experiencing.

I don't know if this may help somewhat but my androids since my old Lenovo P700i (RIP), I have always removed GAPPS, except Google Play and Google Play Store, and other services related to those two. All others are taken off my phone. I don't even have Google Chrome. I use Mozilla Firefox instead.
[Xperia Z1 General] amnher:
I do that also but yeah sometimes not but but most of the time yes. Well anyway this is also a known issue even on Z2 an Z3 when they were on 5.0.2 but upon upgrade to 5.1.1 its now fine. I am hoping that 5.1.1 will be released very very soon. Though as a sony user since 2010. This updates though certified may or may not come very soon. Sometimes the certified ones are not released. Well I am still enjoying kitkat's multitasking though for now.

Wow T2 Ultra Dual has been given with 5.1.1 though the correct order would be z1 series first before them. What the hell sony is doing >.<

Z1 user here..

I would like to seek for your help on my z1, it suddenly display "no service" on the upper left of the lcd and i don't have any network signal.

i experience it when i upgrade my phone to lollipop 5.1.1. can i downgrade my phone to kitkat?
[Xperia Z1 General] amnher:
have you tried a factor reset?
[Xperia Z1 General] motorazrv3:
Yes you can. But downgrade is only possible with flashtool. Sony official tools don't support downgrade.

Use flashtool, download your needed ftf file and flash the phone.
[Xperia Z1 General] lonesome10:
[MENTION=4410262]motorazrv3[/MENTION]

do you have a link for a stock kitkat ftf file where i can download it. i would like to ask why some ftf file is generic or unbranded?

also some ftf file selects region, does SG ftf firmware can be use in my z1 and i can have signal here in the philippines?

Hi guys! Newbie here for rooting my Z1. Since it is now official that Sony stopped supporting Z1 up to 5.1.1 only, can you help me rooting my phone? I've been reading 30 minutes of rooting Z1. (though I did already in my Arc 2 years ago but I don't remember now how to or there are new ways for rooting compared to my Arc before)

BTW, my phone is running the latest Lollipop 5.1.1 FW. Is it correct for this method:

1. Downgrade to latest 5.0.2 FW (where can I get one? XperiFirm?)

2. Root via Kingroot (or there are better ways than this?)

3. Flash pre-rooted 5.1.1 stock FW (what does pre-rooted mean and how to make a pre-rooted FW if FW is to be downloaded over XperiFirm?)

Let me know if I missed something. Thanks for your reply, mates!
[Xperia Z1 General] Deathschythe33:
1. There are alot of 5.0.2 FTFs in here. Just look around.

2. Yes, this is the easiest way to root 5.0.2.

3. [You are missing this] You need to have a custom recovery, else you will not be able to flash the pre-rooted FW.

4. Flash pre-rooted 5.1.1 FW

a. Flash the pre-rooted system.img through the custom recovery you have installed on your phone.

b. Flash the rest of the 5.1.1 FW using flashtools, exclude system.
[Xperia Z1 General] botski:
i will get my z1 later ;) haha i'm too late.
[Xperia Z1 General] botski:
Guys, please teach me how to install custom recovery?
[Xperia Z1 General] motorazrv3:
Root your phone, Google for nuts xz dual recovery, download the Recovery installer.

Install recovery. Be happy.
[Xperia Z1 General] botski:
almost mate :) thank you!
[Xperia Z1 General] botski:
guys, please teach me how to go to recovery mode? i can't enter. :(

---------- Post added at 04:32 AM ---------- Previous post was at 04:26 AM ----------

is this 5.1.1?
[Xperia Z1 General] xasbo:
Yes.
[Xperia Z1 General] motorazrv3:
If you have installed custom recovery successfully then power on your phone. The phone will vibrated and the green led brights up. Press and hold Vol + for 1 recovery or press and hold Vol - for second recovery.

Alternatively you can download ndr utils from play store. Run it and Grant super user rights. Define your first custom recovery. Hit boot to first custom recovery. Your phone should reboot and enter recovery.
[Xperia Z1 General] botski:
Thank you so much mate. But when i tried to run ndrutils not asking for root and i cant choose primary recovery.
[Xperia Z1 General] motorazrv3:
Are you sure your phone is rooted. Open your root ap and look if ndr utils is allowed to get root.
[Xperia Z1 General] botski:
yes mate, i install this stock rom pre-rooted:

thanks mate! is this deodex?
[Xperia Z1 General] motorazrv3:
I don't remember the routine installing the Recovery. I downloaded the installer and run it on my windows pc and the Recovery was installed.

To enter recovery you can also try :

Download terminal emulator from playstore. Open it and Grant root. Type su and hit enter. Type reboot recovery and hit enter. Your phone should reboot to recovery.
[Xperia Z1 General] botski:
Okay mate! I will try the second option.

---------- Post added at 10:55 AM ---------- Previous post was at 10:51 AM ----------

I think mate i don't have recovery.
[Xperia Z1 General] motorazrv3:
Just to make things clear.

Your phone was rooted and a custom recovery installed. Then you downloaded the zip you linked to upgrade to 5.1.1.

If you did that you are actually on 5.1.1 with root. The zip you flashed doesn't include a custom recovery, only root.

If you are rooted than just run the windows installer for nuts xzdr. This way you should get your custom recovery.

Good luck.
[Xperia Z1 General] botski:
all good now mate :) can you help me to install xposed and framework?
[Xperia Z1 General] motorazrv3:
All good? What happened?

No I can't. I haven installed xposed jet. And I won't do. But if I remember correct there is a thread here which explains what to do to get xposed on your phone.
[Xperia Z1 General] botski:
i managed to install TWRP and xposed and the framework! thank you so much for the help.
[Xperia Z1 General] xasbo:
No, it's not. Totally stock except for pre-root + custom recovery
[Xperia Z1 General] rency_0722:
Hi! I am searching for a customized PH 5.0.2 based in .270 but there are none, I only saw one, which is the first release .242. Besides, there is a customized SG for .270, which I think will work but I'm really not sure of.

Well, for the step 4, are those two different choices of flashing pre-rooted 5.1.1? Thanks! Gotta learn more of this.
[Xperia Z1 General] Deathschythe33:
It's ok to install .242, the OTA is incremental it doesn't jump straight to 5.1.1 so before you get 5.1.1, root your phone so you can have a custom recovery installed. Then install a pre-rooted 5.1.1

No, it's not 2 separate ways of root. You see, when you run a FTF through PRFCreator it produces a pre-rooted system.img that can be flashed though a custom recovery. Once you flashed it, the next step is to flash the rest of the FTF usong Flashtool but make sure you EXCLUDE system.
[Xperia Z1 General] amnher:
I cant seem to find system.img? only system.sin inside the zip created by PRF CREATOR

---------- Post added at 05:58 PM ---------- Previous post was at 05:37 PM ----------

Anyway I tried flashing the prerooted zip file and then flash the rest of the ftf excluding the system and I get at the end of flashtool this error

Now my phone wont boot and it says

"Software Update Failed. Make sure that your phone is connected to the computer and try again..."
[Xperia Z1 General] Deathschythe33:
Ah, yes my apologies I mixed system.img vs. system.sin, if you are making a pre-rooted 5.1.1 use this thread it details how to create a pre-rooted 5.0.2 but it is the same for 5.1.1

Question my xperia C6903 is stock on jellybean how to update to kitkat or lollipop?
[Xperia Z1 General] SUPERUSER:
If your bootloader is locked and phone is untouched you should be able to open the settings app.

Go to about phone and check for updates. Hopefully Sony still have the OTA files on their servers.

If so then just let the phone update it self and go back to settings app after it reboots as many times until it says there is no more updates. ;)

If Sony has removed the files from their servers you can manually flash a stock rom with flashtool.

http://www.flashtool.net/downloads.php

It might be a bit tiresome if you are running windows 10 because you need to disable driver signature verification before you install the drivers.

How to use flashtool:

http://www.xperiablog.net/2016/03/12/install-xperia-marshmallow-using-flashtool-and-xperifirm-guide/

In xperiafirm select honami and then C6903 and check all and wait for list to update.

And select the rom that might fit your location.

Hi got my z1 from hot gadgets and it's suffering from the touch screen issue, Touch fails to respond and can easily be seen through the service setting and sketch app.

Is this software or hardware related?
[Xperia Z1 General] nikkorob:
Oh okay. I ddnt know that one rule . Btw i cant tolerate the heat my sony produces when i play hard core games.. Sigh.. Nonetheless , its a good phone. All my friends and mates are amazed by how amazing the design was. They are willing to gve up their present phone for this one ;)
[Xperia Z1 General] brapicoco:
I think that's normal for phones especially quad core and z1 has a high clock speed. First it really gets hot and eventually temp goes down after playing the game for a while, That's my experience. I'm playing dungeon hunter 4, asphalt 8 and Frontline commando. However, the touch screen issue really is bothering the overall user experience.. :(
[Xperia Z1 General] zyxel25:
try reparing ung phone through pcc if it not fixed get a replacement.
[Xperia Z1 General] brapicoco:
Done that even with SUS and problem is still there, store wont release a replacement since it's already past 3 days. I dont want also to leave the phone there and sent it for repair since I had a bad experience regarding sending for repairs. Once the unit came back some of the parts were missing and I dont want that happening with my z1.

I hope this is can be fixed through a software update in the future as other xperia owners such as tipo, miro and sola have installed a third party app that calibrated their screen. Again, I hope that same app can be installed in z1 or other people can develop a screen calibration.
[Xperia Z1 General] nikkorob:
Yeah definitely agree with u on that one.it is really bothering me. The touchscreen would eventually loss its ability to function that much or as responsive as it should be. I hope kitkat 4.4 would make necessary changes.and do u have any problems with the menu keys below when playing games? I would like it stayed hidden like when watching movies. I found a thread that would autohide it but u have to root ur phone , which i find tiring and i have to wipe down all my memory. Any tips tho? Does that dont bother u, bro?
[Xperia Z1 General] Morlock O:
note sure if there is any phone out there that doesn't heat up when you play hard core games...

I play Asphalt 8, NBA 2k14 and yes they heat up but my friends Note 3 and LG G2 and IPhone 5 all heat up with the same game as well...
[Xperia Z1 General] brapicoco:
No bro, since I really cant play games that much also because of the annoying touch screen. However, given that the on screen buttons are there I really am not bothered by that since Z1 has adequate bezels. On the contrary it bothers me on my previous ZL.

It's really up to the users preference though. But I hope the touchscreen problems be fixed the soonest..
[Xperia Z1 General] brapicoco:
I really regret that I bought my z1 from hot gadgets (2nd transaction with them, first was ZL and had no problems with it) since it really has a touch problem and they insist that they will not replace the unit even if has problems since its past the 3 days replacement.

I'm really afraid to leave it at the store since they will send it for repair and you know here in the PH we have a very bad reputation about repairs. Once the phone comes back it's worse and parts are missing and on top of that they will charge you for the "parts" that they have installed which is unbelievable.

I don't want to take the risk so I hoping that a software update will fix this annoying issue.
[Xperia Z1 General] Morlock O:
I'm quite sure its just a software issue, as I did not have it in the previous firmware. I only had the touch issue after I update to the latest firmware where sony said they increased touch sensitivity.
[Xperia Z1 General] Dandroid2010:
Have you tried factory resetting the phone?
[Xperia Z1 General] brapicoco:
I have the problem even before the latest firmware update and I expected that it will be fixed. However, issue still remains.

Have tried also updating with SUS many times and still it does nothing.
[Xperia Z1 General] junta_mpb:
I'm kinda bummed with my Z1 getting scratches on the glass. They are very fine and you cant feel it at all, but its there. On the screen side, its mostly where my thumb travels and on the back its random. If you are yet to do so, I recommend getting a screen protector.
[Xperia Z1 General] cyrom:

[Xperia Z1 General] Morlock O:
this is a good place to start looking for a service center.

http://www.sony.com.ph/microsite/SonyASC/ServiceCenters.html

for your touch screen issue, first check if any app is affecting it.try to disable apps you are not using in the apps section.

I did have the touch issue for a brief time, I think 1 week or so then it suddenly became ok now. all I remember doing was uninstall apps that runs on the back ground (greenify or any battery saving program, location based wifi, media server etc), then restart the phone and let it settle for a few hours before trying again.
[Xperia Z1 General] brapicoco:
Thanks dude, so you have the issue before and it's good to know that you're not affected anymore.

Can you give me the list of running apps that come with the phone that I can safely disable? since I don't have any other apps installed since I just wiped my phone. What I have disabled only is Hangouts. and uninstalled other useless bloatware.
[Xperia Z1 General] Morlock O:
I did disable:

Google lyrics extension

Google play magazines

Location based wifi

news and weather

setup guide

youtube karaoke extension

I can' t remember the others I have un-installed using root uninstaller

I also went to Movies->settings uncheck get video details
[Xperia Z1 General] brapicoco:
Thanks mate, that's very informative. However, it will really help if you recalled something that you have disabled since maybe that particular app/program maybe contributing to the problem.

EDIT: Have disabled those and still touchscreen goes nuts
[Xperia Z1 General] Morlock O:
going nuts meaning on/off thus producing broken lines?

try to restart it again and let it settle for 30 mins, if it still have problems then definitely hardware issue.

do you have screen protector? sometimes that causes issues as well...
[Xperia Z1 General] brapicoco:
Yes, I have one. But it's very thin.

Going nuts, yes. It produces broken lines and while gaming movement of character is almost impossible.
[Xperia Z1 General] Morlock O:
hmm you may at least try removing the screen protector before sending it to service center.... removing it will be the first thing they will do anyway...
[Xperia Z1 General] brapicoco:
I will try first replicating the issue without the screen guard.. since I plan also changing it together with the customized one attached at the back panel
[Xperia Z1 General] Morlock O:
Sounds good! hope you finally find a fix for your phone...
