[Galaxy Note 4 Q&A, Help & Troubleshooting] darekz:
63% screen time. Did you set up automatic screen timeout for 10 mins? I have mine set to 15 sec and I'm using app called screebl to keep screen on while is not laying flat. Otherwise turns off after 15 secs. The only downside is that you have to remember to turn it off before put it in your pocket (when you use s-view cover it turns off when cover is closed).

Turn off high accuracy location service (gps use a lot of power) until you need to use navigation software. Set location service to power saving mode and that is sufficient for correct weather updates, alerts....
[Galaxy Note 4 Q&A, Help & Troubleshooting] 1Neo:
ok great (: its Does it matter if its with cable or normal charging?

ok thank you for your advice.

i use also for 15 sec automatic screen, i changed alot of settings,

settings- display screen - mode - basic.

enable auto adjust screen tone.

smart stay enable.

daydream off

touch light key duration 1.5s

screen timeout 15s

brightness -5 auto

gps - off

google sync - only contacts.

what should i do more?

btw this is my new power saving settings:

and the history:

and yesterday i spoke so many times (voice calls the screen drops to 8% and the voice calls to 40-50% something strange.

and what do you say about it now? it is good?

and again about the red flickering screen thats happend me yesterday i most to get answer about it im a little bit worry and i think to do a reset settings (dont know how) should i have to do? its doesnt happend me again, only one time yesterday but im a little bit worried.

i talked about this,

when i turn on devs optons and when i turn off the scale animation the screen start to flickering on red colors, after 5-10 sec its stopped and never happend again.

should i have to worried? btw like i said i already removed/hide the devs options from settings (clear data settings did that)

i found a picture from another website of the same problem thats happend to me but for nexus,
[Galaxy Note 4 Q&A, Help & Troubleshooting] darekz:
Auto adjust screen tone turns on sensor and that use additional power, smart stay turns on camera to sense your face, using power again. Manualy shut down some unneeded apps running in background

Mine settings
[Galaxy Note 4 Q&A, Help & Troubleshooting] 1Neo:
ok thanks.

btw guys can anyone answer me about the flickering screen thats happend me before 2 days? if is normal? if i have to worry about?

and one more quesiton,

my home button start to do noises/clicking noises sometimes it is normal?
[Galaxy Note 4 Q&A, Help & Troubleshooting] zurkx:
set your background to full black with the file i posted up and set all the effects to off in developer options as instructed. you should not see any flickering.

also you should set your keys to silent to avoid the clicking noise.
[Galaxy Note 4 Q&A, Help & Troubleshooting] 1Neo:
the flickering screen happened only once its some bug or something.

and what you mean set my kets to silent? i mean when i click the home button its make some noises of clicking.

thanks again.

omg! I dont get it!!!

Galaxy note 4 has many useful features but as what i am reading here base on your comments,

all this features must be shutoff to prevent battery consumption!!!

If this is the case all the best feature of this phone will unusable because it eats a lot of battery!!!!!

Is there anyway how to maintain good battery percentage without trying to disable all features that this phone have????
[Galaxy Note 4 Q&A, Help & Troubleshooting] darekz:
Turn them off only when that are your preferences. It is like driving car with air conditioning turned on all the time and complaining about fuel usage. If you choose that, keep topping off gas tank.

I personally keep most features on (no touch sound, vibration, auto tone adjustment) and keep charging my phone every night. Im not battery freak and always buying phones with replacable batteries.
[Galaxy Note 4 Q&A, Help & Troubleshooting] 1Neo:
anyone?

and about the battery i hope its will be better in few days (look up my settings and what i did to try to save my battery)
[Galaxy Note 4 Q&A, Help & Troubleshooting] razno:
Problem is, phone first must survive until night. :)

With s5 sd all on including high precision GPS I didn't have to think one minute about that. But either 910c i have. Not what I really expected.
[Galaxy Note 4 Q&A, Help & Troubleshooting] easycure1974:
And yes it is fun to buy a smartphone and have to shut everything of doing it as smart as a Nokia 3310 just to survive the day :) The Note series has been well known for their great battery but the Note 4 is pretty bad. Had to root mine and install Greenify and other things to make the battery acceptable. My Z2 and Z3 fared much better and made it to late evening wihtout any tweaks at all. And thats without turning stamina mode on. Even exchanged my phone believing it was defect. But the new one with two different batteries is as bad as the first one. Almost thinking of buying the stupid 10 000 mAh Zero lemon battery :)
[Galaxy Note 4 Q&A, Help & Troubleshooting] darekz:
T-Mobile US version, no power saving turned on and no complaints from me.
[Galaxy Note 4 Q&A, Help & Troubleshooting] 1Neo:
guys any one can help me with few more questions?

1. fast charging settings drains/drops the battery faster?

2. my home button starts to do clicking noises its normal?

3. antivirus is recommend for the note 4? i downloaded avs its ok or not necessary?

4. i put my mobile networks - network mode WCDMA/GSM (auto connect) its mean no 4G, its saves more battery? cuz the lte/WCDMA/GSM (4G) not always show on my device. what should i put and if its saves battery?

thanks guys!
[Galaxy Note 4 Q&A, Help & Troubleshooting] zurkx:
1. yes fast charging is bad for the battery. if you want good battery life disable it and charge wirelessly.

2. yes its normal unless you disable the noises in your settings. (button click noise)

3. not necessary.

4. yes 3G uses less battery than 4G.
[Galaxy Note 4 Q&A, Help & Troubleshooting] 1Neo:
hey guys i have more questions,

1. so if i dont have 4g in my area so to put it on 3g only? (WCDMA/GSM) its will be better?

2. And about the sor/idle let me understand something, SOT = Screen On Time thats i already know buts whats is really means? is playing games/apps/internet/whatsapp and everything else?

and idle is when im dont use my phone? (Do not use it at allׁׁׂ)

if yes so my SOT is like 5-6 hours and about the idle i checked it while im sleeping i had 100% i woke up after 8-9 hours and the phone was 93% ( i had some voice calls and whatsapp messagesi didnt answer during the night)

if is not what i say so i will glad for explanation.

here is some screen shots from my power saving in settings, i will be glad if someone can tell me if its ok,

power saving:

screen use details:

history deatils: (what is the yellowgreen/gray in the network signal? thats mean i have a bad signal?)

View attachment 157235

my settings in display are:

fast charging : off (just turned it off to check charging without it, still didnt charge it while it off i will test it soon)

brightness - auto -5

screen rotation - on

smart stay - on

screen timeout - 15 seconds

screen mode - basic

auto adjust screen tone - on

daydream - off

led indictator - on

touch key light duration - 1.5 seconds

increate touch senstivity: off

sounds settings:

vibrate when ringing: on

feedback:

dailing keypad tone: off

touch sounds: off

screen lock sound: off

haptic feedback: off

sound when tapped: on

vibrate when tapped: off

location: off (This is related to the battery? or should i put it on?)

what should i do more?

I will be happy with the recommendations.

3 .today i was in the sunlight and the screen was colorful its normal? i heard its beacuse the auto brightness.

and here is a sub question, auto brightness -5 is good for battery or should i put +5 auto or to cancel the auto and put in on the middle? what is the best?

thanks!

Looks like Cellular part doesn't work. Reboot on setup screen, and endless searching when looking for providers.

Am wondering if this has an apns-conf.xml?

Baseband isn't installed?

Never mind, apns-conf is included.

Also notice it only has 2 and 3g capability, even if it worked. No LTE

Screen rotation doesn't work and gets stuck in portrait mode when Hangouts opened.

Wifi drops out and will not auto-connect (sporadic)

Camera Forces closes

GPS doesn't work (locations doesn't work with wifi either)

Seems these issues are also on the Z2 Phone.

Ive also noted on the downloads page there are 2 download files with the same file name. However, when zip opened, the file image sizes are different.

Are they indeed 2 different builds? After redownloading, it is indeed so. Pity there isn't a date before downloading. (I know why)

Oh yes, one more thing. Adfly needs to go. It's fair enough I paid for the premium speed, but the adfly is against the rules.

Hi there,

Any chance to see a 4.4 AOSP for the Z2 tablet ?

I'd like to use XPosed but that can't be done in LOL I think...

I know that there is a CM 11 for the Z2 Tablet... but some features I'd like to get on my Tablet using Gravity Box won't work as the things are modded by CM (i.e. : the QuickSettings)

AOSP exists for the Z2 Phone... why not for the Tablet ?

If needed, I have a running Linux VM to build it myself... but have not been really succesful so far :(

[Xperia Z2 Tablet Original Android Development] :
Adventures in Free Xperia land driving Z2 Tablet.

First of all : infinite kudos and congrats to Free Xperia and Sony!

Next: I am grown up Android user and I do not complain, I comment...

Here go

I got (a present) a (nice!) Z2 Tablet (4G/SGP521) 1 day ago.

I upgraded to 23.0.1.A.0.167 4.4.4, unlocked bootloader, installed

TWRP 2.8.5.0, which I only got to work by installing CM-12.1.

CM ran fine

But, what I really fancyed is AOSP. So I installed it (5.1 castor) and

it runs just fine as well.

Still, here are my comments:

AOSP is, as I expected and wanted, very minimal, but, perhaps, too

minimal for me...

There is no google play service, but, so what, one can flash

gapps. However: to flash anything one needs to boot custom

recovery. Here is my issue: I could not figure out how to boot into

recovery (TWRP 2.8.5.0 in my case).

All standard recommendations fail (using adb reboot recovery, or

holding/tapping volup, after fastboot reboot, etc...).

So, right now I reverted back to (so far, excellent) Free Xperia

CM-12.1 (which I had backed up with TWRP).

So with AOSP I feel like 'close but no cigar': how do I install more

Gapps and later Super User if I cannot boot into recovery?
[Xperia Z2 Tablet Original Android Development] :
I would not universally recommend that step.

At least on my Z2 SGP521 it removed filesystem from cache partition and AOSP boot did not reach beyond android logo.

Luckily I could connect with adb and create ext4 filesystem on cache partition. Next reboot, AOSP booted complete.
[Xperia Z2 Tablet Original Android Development] :
I got a way around it by only fastboot flashing aosp system and aosp

userdata but keeping cm boot

So I could still boot recovery and install supersu and gapps from

there

Next I fastboot flashed aosp boot.

Nice fast lean ROM, as known: camera not yet working.

One question, tablet looks like a big phone in terms of user interface: all GUI

elements are big. Is there a way to adjust DPI as to fit more on the

highres display?
[Xperia Z2 Tablet Original Android Development] :
The castor 150331 build is getting a bit old as compared to other recent 150515 builds ...

Can we pls get a more recent build? Also, are changelogs somewhere to be found?

Have a great day.
[Xperia Z2 Tablet Original Android Development] :
Would FXP mind publishing the exact valid build recipe for AOSP? Or

pointing to an URL where such recipe is written?

Sony has kindly done so and I can build AOSP just fine following

their recipe.

But to build FXP AOSP variant I do not know exactly what to put in

local manifest and which patches to cherrypick and to apply or not and when.

I tried to hack my way but failed, like: I could not even choose to

build castor. That's of course because perhaps I did not try hard

enough and need to be taken by the hand to follow the correct path.

I build free software for 20 years now and typically it is not

sufficient to just have the source code avialable. One must also

provide a valid build recipe.

Having such recipe I can build castor AOSP FXP style myself instead

of having to ask.

So if FXP reads this, please kindly do as Sony kindly does. Not only

provide repositories but also working build recipe.

[MENTION=5414600]alesyt0h[/MENTION] : I did not try latest AOSP (yet) as I am happy with latest CM. Perhaps I'll try anyway (soon), just for fun. Feel free to try as well.
[Xperia Z2 Tablet Original Android Development] :
I tried combination:

- AOSP_L_MR1_150522_castor

- Slim_normal_gapps.BETA.5.1.build.0.x-20150523

- UPDATE-SuperSU-v2.46

and

- camera does not (yet) work

- youtube looks odd coloured indeed (tried a few developer options to fix it too)

Reverted back to

FXP-cm-12.1-20150517-UNOFFICIAL-castor

via

openrecovery-twrp-2.8.5.0-castor

Still: I look forward to have AOSP with defects fixed on castor as it really feels best.

@FXP : please continue the excellent work!

question: since FXP CM camera and youtube works, would it be possibe to provide an update.zip just to bring same functionality to FXP AOSP?
[Xperia Z2 Tablet Original Android Development] alesyt0h:
Thanks dude!
[Xperia Z2 Tablet Original Android Development] :
Dear FXP friends

I know there is an issue with booting some xperia recoveries, but,

nonetheless, for SGP521, is there any particular recovery img you

recommend to put there? Or does it not matter at all what one puts there?

(put = dd ;))

Thanks for your excellent work, and sorry for my limited understanding.

let me repeat: the fxp/sony free/open source initiative is unique!

[Xperia Z2 Tablet Original Android Development] Dior DNA:
AOSP_L_MR1_151203_castor.zip

I notice there is AOSP_L_MR1_151203_castor.zip on FXP which. I assume, will have new snapshot, zip v14 as announced in http://xdaforums.com/showpost.php?p=64111291&postcount=5

Did anyone verify if camera works on LTE Z2 'castor' tablet and if youtube artifacts are gone?

Also, will CM updates come that take advantage of the zip v14 new snapshot?

I run CM which works perfect but I would prefer, or, at least, want to try running AOSP if above issues are fixed.

Thanks FXP for great work!
