I had to downgrade back to KitKat which I wrote about in the downgrade thread: http://xdaforums.com/xperia-z/general/downgrade-lollipop-to-kitkat-4-4-4-guide-t3114081

The reasons was:

- Battery drain. First it said 3 days and 2 hours with stamina mode on, did hardly last one day. Screentime was bad, 1% drop every 1-2 minutes, a bit less when not using, dont know exactly but 1 % every 10 minutes.

- Phone turning of itself. Had it in my pocket, took it out and it was of, turned it on and later it was of again. turned it on and left it on the table, after a while it tuned of itself again.

- Autofocus problem in Camera. Made video capture, when it saw the faces if focused on them which is a good function idea and might work if you make an interview. People moving or dancing doesn't work. In a bright room the video got lighter and darker every second. Sometimes the focus didn't worked at all so it got all blurry for 5 seconds, that happened repeatedly.

I know that many had problems with battery drain (and heating which I also had problem with) but did anyone had problems that the phone tuned of itself in Lollipop and that the autofocus is terrible?
[Xperia Z General] theduke7:
not really, 1st time i hear this problem... this maybe a a problem with flashing , did you tick wipe Cache & Data on flashtool before flashing?

also you should do a factory reset both before and after flashing LP .
[Xperia Z General] oskar_08:
Well I used Sony PC Companion to update to LP so I didn't used Flashtool at all. Didn't do a factory reset before either, only after. Someone wrote that it's best to do that also but when I read that it was already too late.

I will wait until Sony gives us a new update with bug-fixes (if we get that) and then I will do as you said and hope for the best! Meanwhile I will keep using KitKat.
[Xperia Z General] lee480:
Have a Z upgraded to lollipop. As usual, there will be always an initial battery drain that will dissappear after several days. Excellent battery life now! Good job Sony! One of the best update given to this 2+ year old phone.
[Xperia Z General] poran123:
once my phone had rebooted after i unplugged the charger... i dont know why.. till now its working fine, hope it wont repeat
[Xperia Z General] natibongo:
Well said peeps

These are my observations:

1. I noticed the battery drain problem and decided to install system app remover from the play store to remove some unwanted apps and saw some improvements

2. I regularly clear recent used apps(though apps from the play store can automatically do that) decided to do it manually

3. I use WiFi often because 3G/LTE drains battery like s**t

4. Also, I try to open apps like Facebook and Twitter from browser instead from the apps itself and that helps a lot

5. I reduce screen brightness to the minimum based on lighting conditions
[Xperia Z General] comax70:
After restore backup from twrp sd internal don't work bug twrp lollipop?
[Xperia Z General] jamminen:
So i did OTA update, but i did factory resets, but does it seem so that those who updated using flashtool don't have problems? Could it be the option to wipe cache/data, which maybe doesn't happen in OTA update? My phone really drained juice twice as much when used, not on standby.

I haven't rooted this because it has just been so good there was no need. And didn't want to brick it :) But at the time when i was a bit curious to root it, i didn't find working method.

BTW, i used flashtool to return to kitkat, but my phone went to bootloop. Luckily it shut down vol up+ power, and i got PC Companion to install latest rom it has to offer and for some reason it was 4.4 :) So i don't know if i dare to try flashing LP with it...

I got an idea why the charging is slow. It's because the intensive battery consumption, the apps that are running use the power. When sleeping, stamina mode kicks in and prevents it, but when on charger stamina mode does not apply.
[Xperia Z General] theduke7:
so Ironically , it just happened to me, the phone just shut down by itself, it was beside me, and a friend called another mobile i have and told me that this number is offline, so i checked and found it turned off... it didn't want to turn on either, i plugged the charging cable and also it seemed that it was bricked, but i clicked the power button and the Vol up + and it turned on to charging, i turned on normally and it worked...

so i don't know what to till you really,.

this at least on my part a Bug, i hope it's something i did and it doesn't re occur , i'll do some research and give it some time and get back to you.

that said , up until this happened i had a great experience with lollipop, and there's a way to root it, you root with Kigroot version 4.1 and then theres a script that replaces it with Super SU... there's a thread about it.

also the law sound there's a couple of mods that returns the sound to normal, they're on the cross development section i think, even the batter issue can be resolved without rooting by just turning off LTE , and with root greenify seems to do a good job ( it even stops apps on sleep)...

so again as i also now have the sudden turn off issue i'll be getting back and report as soon as i find out anything...

hope all goes well with you...
[Xperia Z General] thunder141:
There is a known Bug. Turning mobile data off will Not reduce battery drain. I use flight mode after using Mobile data, then disable flight mode and battery drain gets a little bit better

No, I didn't. It's been a week now. I need to call them, ask what the heck is going on and get my $12 back for overnight shipping. I called them on Friday and they said it will be delayed a few days.

[Huawei P8 Questions & Answers] me_is_rushin:
Mine was ordered on June 4th with regular shipping and arrived June 8th.

As far as tracking it did not show up in an email, however, logging into the huawei website I was able to find a tracking number there. Mine was delivered via USPS.
[Huawei P8 Questions & Answers] Kiwi_in_KC:
I ordered on the evening of June 4th and received the phone, case, bluetooth speaker & $50 tracfone activation code on June 11th delivered by UPS. It showed as from Amazon.com with the origin of Middleton, DE. The Net10 BYOP activation kit was delivered by the USPS on Monday June 8th.

Phone is fine for what it cost with the promotional deal. I don't care for the Huawei skin/modifications so am looking forward to some custom ROMs. Also hope that Huawei gets a lollipop update out in the next month or two.

I found an auto rotation bug that stops the phone from correctly orienting when it is rotated 180 degrees in portrait position.

No NFC, 5GHz WiFi or wireless charging though I can live without those while I wait for the next Google Nexus phone/s in the fall. This is a gap phone as I dropped my Nexus 5 and the screen is cracked enough to be an annoyance to use. I would have sent it in to LG to get repaired however I can't be without a phone until it is returned.

bought it as dedicated sports phone besides my n5 ... now im thinkin about using it as my daily driver . ---but not with EMUI

if huawei would provide a vanilla rom - that would be great

if cm was available - that would be awesome.

but i read that isnt going to be that easy.

but regarding a vanilla version of lollipop you can write them a recomandation

Agree that EMUI is not the best for home Screen. But if you install Nova launcher and then go into settings, apps, manage defaults: there you can set Nova as default home. It works very well and the battery life far exceeds any other phone I've used (S3 and Note 2).

Won't be anything until someone ports a custom recovery to make things easier. Personally can't wait to get AOSP on. Xposed is currently not functioning on this phone with emui as well. Really irritates me that OTG is not supported too, so no USB devices. Otherwise, after rooting at least most off the root apps work properly.

Get huawei update unpacker.

U need stock rom for P8 Lite (http://xdaforums.com/android/development/huawei-p8-p8-lite-stock-rom-firmware-t3176374) or Your B046.

Unpack UPDATE.APK Copy system.img to Your minimal adb & fastboot location.

Run CMD as admin, run this:

fastboot flash system system.img

fasboot flash recovery recovery.img

@UP(This is recovery, not recovery1 or recovery2)

fastboot flash boot boot.img

fasboot flash cust cust.img

Those are basic files for repairing every rom error.

Also U can try to flash every .img file from ur unpacked update.apk. Then u will have full rom with every **** there is.

Run Updater from Settings, but be aware that B120 has broken my WiFi (Mac adress gets deleted), so I'm not ever again installing any official update. Will be waiting for full roms.

P8 Lite doesn't have yet working custom recovery. As for roms, eventually we will get CM, but for now: Root, Adaway, Droidwall and root app remover.

True. Some girl from Emui dev team replied with info that they're preparing clean base rom for further developing.

Turned off unwanted Google **** and now it works 54h with normal use (~1h of calling, ~60 SMS, ~1,5h Firefox, ~1h Music on way to work, etc)

I Wanted to say that I, too, have this problem of double letters which is so annying. I cannot understand, how a phone with so many functions still suffers from basic problems. Its unacceptable from Huwaei to not solve this issue from the first complaints received. Its almost been 4 months since the phone came out and still no solution. Is it hardware or software related problem?

I am actually currently looking into porting CM to P8 Lite (ALE-21 version).

I just started this week and the kernel sources were not quite ready to be compiled but that part is done now and the kernel compiles.

Next step is to create custom boot.img with custom kernel and getting the p8 Lite ready as CM device. It'll all take time though ;)

If somebody is brave I do have a boot.img available with a custom kernel (currently just the default config used)

USE AT YOUR OWN RISK

https://www.dropbox.com/s/mall7o43rrzvsz1/new_boot.img?dl=0

use "fastboot flash boot new_boot.img" I have not tested myself yet though.

If you need to go back here is the boot.img of B136 firmware

https://www.dropbox.com/s/fi8wn97ccxfl8vu/BOOT_B136_original.img?dl=0

or ideally make boot.img backup via TWRP and restore that one via fastboot if you used twrp for boot.img backup also test flashing it back before trying above boot.img so you are on the safe side..
[Huawei P8 Questions & Answers] jdstrydom:
Hi,

fastboot flashed the "new" bootloader, and I am sad to say that it did not boot for me. It just freezes at the Huawei logo; logcat not available so early in the boot process.

I flashed the B136 bootloader you provided, and all good again except for wifi; will sort that with the backup boot.img I have.

Hi Slade87, you seem to be the furthest along with any kind of dev'ing on the p8 lite ALE-l21. it has been a while, so I am just interested whether you have been able to make any progress on this? Meaning the boot.img & wifi drivers etc. Not pushing for any type of eta or whatever; just interested in what kind of obstacles you might have been running into. If the kernel / boot.img is sorted will you or other devs be able to compile with for example AOSP / CM; or will the supplied kernel sources restrict everyone to emui stock based roms?

Thanks
