Just to share an alternative perspective, I actually find it very useful to know if a certain build is more friendly towards using an existing data.img - sometimes I arrive to updating a day or two after the release and reading folks' experience is a great indicator to whether it's safe to keep the old image (which does save lots of time, at least to me) or not.

Of course, when Cope specifically says that a new image is required, it's a waste of time to not create one, but on the 6/25 release post I couldn't find such instruction (http://xdaforums.com/showpost.php?p=15085626&postcount=11180).

Battery drain observation

i have observed that whenever there is a notification lying on the taskbar i.e sms, missed call or market update the battery drainage is high around 60-70mah even with the screen off and when no notification its 6-8mah....

just wanted to trigger the attention of the Guru's on this matter....

60mA drain with notification

I found out and posted about that roughly 400 pags ago ;)

But, I noticed that system own notifs, like gmail, original email app, market updates do not trigger the higher drain, its only 3rd party apps like k-9, goSMS, etc.

With go sms I found the solution to be quite simple, just disable pop up of new sms and enable private notif (only says "new msg", no preview of text in notif area). With these settings I had no more excessive drain.

I got rid of K-9 because of excessive battery drain, so that problem was solved as well...

Its actually the same with most of the apps, if they are running and you dont exit them (by pressing home button) but only turn off the screen and they stay in foreground, I found that most of them then cause a ~ 60mA drain.

Change any setting

Ok, this is not a problem report but merely a little request, can somone try to make a change in any of the settings (like change date format, or enable vol. keys to unlock phone in cyan settings), post what they changed, what build they are on and if the change actually got applied?

I noticed this a few builds back but actually thought it was related to that specific setting I was trying to change. However just now when trying to enable vol. keys as unlock, I noticed that all the settings I try to change are back to default when I press the back button and then go into that menu again... :confused:

might be new data.img time...

Hi, you're not alone (postes it some posts ago).

Still also have the night pb : after with radio on and data/sync off, i need to register the network manually...

Overall, with this build, i have a very few FC (less than 5 since 25, BT autoconnect and seems more stable, and no pb with my hidden WPA2 wifi.

No more restart since yesterday (linked to ext2 size?)

Edit : tried volume button in CM, and it works as ticked. I tried others status bar tweak, and it's always kept... if you need another specific test;-)

Hmmm i don't know why noone is answearing on dozen of posts "batterry drain issues" like it's not an issue?!?

It's major issue and ROM is almoust imposible to use with that issue...

Who cares if app is working good and how much you can overclock when you have to carry it on the charger...

It's not some app problem, it's not notification problem...

Cause only thing that helped was changing the kernell... and i'm not the only one...

So please, just confirm it's an isue and tell us that work is in progress on that issue...

p.s. which kernell do i use now is irelevant but everything is perfect again after changing kernel to "someone else's" :(

Please say something...

[HD2 Android SD Development] antaed:
Hi Cope, Warren, guys

I'm sorry if I bother you with my issue but it seems that I have nowhere else to go with this.

Moreover, I love this build and you are true developers with the kind of knowledge that could hopefully provide a solution for my issue.

To get to the point, the g-sensor stopped working in Android ever since I had my screen replaced. It's not a hardware issue because it works in wm6.5 and wp7.

Also, it seems I'm not the only one having this:

http://xdaforums.com/showthread.php?t=1069578

My logic says it must be a kernel issue caused by my new harware not being recognised.

I ran Alogcat and found these lines in the log, which seem to confirm that what I suspect might be true:

E/Sensors ( 311): Couldn't open /dev/akm8973_aot (No such file or directory)

E/Sensors ( 311): ECS_IOCTL_APP_SET_XXX failed (Bad file number)

E/SensorService( 311): Error activating sensor 0 (Bad file number)

I did a google search for akm873 and found the sensor datasheet - see attached.

Any help would be highly appreciated, thanks :)

[HD2 Android SD Development] evo1rs:
Have a look for 'sensor test' on the market and see what values are changing because AK8973 is the magnetic and orientation sensor, bma150 is the g-sensor.

You are absolutely right, battery is one if not the main concern!

I have posted findings and was told to zip it, so best is to not bother until a release comes saying "ok, we are now back up to date" or similar.

In the mean time you can consider yourself lucky as you have found the perfect solution to your prblem. Who cares what kernel you are using?

Use the one that suits your needs best and atm there is only one out there that does that for me. Don't think I will change that anytime soon as I am absolutely 100% satisfied regarding my smartphone needs! Only thing that could make it better would be 128MHz enabled, but thats not really bothering me that much, especially compared to all the downsides of the others out there.

Search for my posts a few pages back (best under Advanced search), I have detailed there 2 ways how it works for me, depending on whether you want to connect a phone or a laptop to your HD2.
[HD2 Android SD Development] antaed:
Thanks for your quick reply evo1rs.

Accelerometer, compass and magnetic field sensor do not work - please see the screenshots.

Edit:

maybe that akm8973_aot file is created on boot.

for some reason, it wasn't created on my phone.

[HD2 Android SD Development] hobo2009:
Geenyous, you are really a genious! ;)

I can now unlock the phone. What I did was the following:

1. Made the adaptation from 240 to 202 in the build.prop file (located at \Android\240buildprop\root\system\)

2. Copy (not move) the file from \Android\240buildprop\root\system\ to \Android

Moved back

Because of excessive battery drain on 0623 build I have moved back to 0604 build which has a good battery life but has two issues

1 led

2 during phone call the screen does not get on immediately after you move it away from your ear...its takes a few seconds and sometimes it does not at all until you press the hardware button

On 0623 build the led and screen getting on was solved....
[HD2 Android SD Development] TheNT:
And it seems to me that it is concern only to few of advanced users like probably you are... 60ma is unaceptable... no worth to do anything unless this is fixed... other things work fine and personally i don't see the point of changing them too much. It's fast, no FC, no problems at all, just battery drain so i can't use it every day...

You are right, why do i change?

Probably cause i want to give some feedback and make this build perfect but seems to me that i will stick to this 0625 build with other kernell until i saw some major improvement...

like:

battery 4-8ma everything on FOR SURE not maybee

Like 720p with more than 15fps...

But it's almoust imposible to see improvement cause major problems go under the carpet...

Who cares about the quadrant score and such things?

That is irelevant... guys buy gameboy ;)

Waren and Cope again... this is not attack on you, just try to put everything on right path... cause this way... there is no road, just crossroad...

You are doing great job and thank you... i still think this is the best build jet, but why don't make it perfect? it can be, cause just with taking other kernell it's near by... and than i could tell to my friends go on XDA and install "that" the only and best build.

Other thing... on front page is article about MCCM build with 720p recording and sense 3.0.

http://www.xda-developers.com/android/hd2-keeps-on-living-sense-3-0-with-working-720p-camera/

Anyone read it?

They said it's first build with 720p recording and it records at 1fps... seems familiar to you :)

That feature is in ACA build long long time ago and someone else is taking credits... why? it's even not mccm's feature, it's practically boxmax build with redisign...

tnx and don't take this as an offensive letter ;)
[HD2 Android SD Development] evo1rs:
Ok so I looked on my phone and I do have the aot file in /dev but it is only visible to certain file explorers and I can't pull it out for you as 'operation not permitted'

I suggest you get astro or androidmate file explorer from market and see if you have the file.

If not then try a fresh install of aca. It should be there as it is part of the build files. Not created I think.

You could try bma 150 recalibration (search this thread for 'bma150') but it may not do anything.

I saw that too, 1fps is what we have now. I think it may be due to running of the SD Card, I believe teh WP7 builds record in 720p, but I could be wrok, so I think it is possible, but probably requires running the rom from NAND.
[HD2 Android SD Development] antaed:
i did clean install the build 3 times already (task29, sd card format, no backup... everything from scratch).

however, i went back to wp7 and checked everything again just to find out the compass doesn't work.

then i flashed the stock wm6.5 rom again and indeed, the compass does not work.

i still don't know why the accelerometer works in windows but not in android...:confused:

i'll send the phone back and we'll see what happens next...

[HD2 Android SD Development] grandmaster_b:
Thought I would post my input and make a request.

This has been my daily build for a number of months now and its near perfect.

This latest one has a 60ma spike which I think is either occuring after you take a call or do send/rec on email I have found by then making a call and hanging up or doing end task on email fixes the drain for me.

When surfing the battery life is terrible the standby is very good as long as you spot the spikes and end them asap.

Warren is there any chance you can include an undervolted version of your kernel as an option ?

I tested the rafpigna kernel 1.9 which is undervolted to 925 I think and the surfing on that lasts much longer than any other kernel yours or Tytung's for me now yours is on par with Tytung for speed and battery standby but not as good as Raf's for actual usage, surfing, gaming etc.

But Bluetooth actually works on yours where as on Raf's it does not with 3.3.4 :)

There you go some positive input and a request/suggestion :)
[HD2 Android SD Development] kergekecske:
Configure and setup your phone . If you cant , write a post like that.
[HD2 Android SD Development] p107r0:
My feeling is that spikes depend also on installed apps and their sync settings, 0625 works very good for me, although I disabled (or set to WiFi only) all non-essentail syncs (weather, RSS etc.), almost no spikes observed, stable 7-10mA, which is a relief compared to 0512 which gave 4 solid spikes per hour.

Power consumption on WiFi can be theoretically reduced using WiFi TX Power. More details on app and checking if it works here.

Yes, volume is up (obiously) but no sound while i up

I restart phone but still the same problem

I cant hear anything of media sound, no sound in youtube etc...

Jun23 Update over last release (kept data.img)

Update went fine - systems seems quick - but now having problems with Bluetooth connectivity. With previous release, paired devices worked as expected, now I keep losing connection (it connects to paired device - then disconnects when I try to initiate a call)

I tried to re-pair the device, but once I de-paired them - I could not them to pair again.

So Bluetooth is broken for me. Only option I see is to install fresh (with fresh data.img) and hope it works - or wait foe next release. Anyone else having bluetooth problems with 6.23 release?? :( :confused:

Did you try 0625?
[HD2 Android SD Development] kdelisle:
Regarding battery drain and alternate kernels. There are 1000 pages of posts and I guarantee that w&c have read EVERY SINGLE ONE. Have you?

In particular, did you read where they are rolling back and testing every single change on the kernel to address problems? Do you think that they are satisfied if the battery drain is high or there are force close issues? Do you think they have not looked at and considered tytung and raf's kernel structure? Would you rather they stop testing and answer each redundant post? Posts that berate the developers and then end by "don't get me wrong, I love the devs" are horrible.

THINK AND READ BEFORE YOU POST.

One thought. Perhaps if it is an APP causing battery drain, there never will be a perfect kernel. It may boil down to choice.

To Justx and shames - you told me months ago that I would get sick of annoying posts. I finally reached my breaking point. I concede - you were right!

+ 1 on this!

I don't normally post but have read every page after following this forum since April.

I'm on the latest release but still use my old data image from ? 28/29 April. No real major issues, mostly what others where getting. I don't like raising issues with any of the builds even if its constructive, don't like to sound like I'm moaning coz I know the devs work so hard putting in lots of hours, but I can also confirm that on this release bt doesn't work for me either, had no problems with any of the other builds. I managed to pair it once or twice with my in car bt and connect but it would quickly disconnect, worked ok in win mo. No big deal for me I'm far too happy with the rest of it :) Big thanx to everyone involved in the build :)
[HD2 Android SD Development] p107r0:
Not to brag, but it works perfectly on mine, therefore invalidating your hypothesis that it's broken in the builds, therefore suggesting that your problem may be of PEBKAC nature, in which case the more adequate wording of you request would sound like "it does not work on mine, what can I do to fix it" or somewhat similar.

On the practical side - did you try any of the following: starting with the fresh build, starting with the fresh data.img, removing all the remebered wifi connections and setting them anew, resetting the router, checking if MAC filtering did not get in the way? Have no other ideas, and anyway feel like an idiot providing unrequisited suggestions.
[HD2 Android SD Development] see_u_then:
I have started with a fresh build, formatted SD card and created a new data.img. This is work wifi so I cannot reset router. I tried the 0608 build again (on the same phone+original data.img) and it can connect to work wifi without any issues. I also tried a random build from another developer and that one works too.

p107r0 - Your IT may be using some other setup for wifi. At work, we are using a hidden network with:

key_mgmt = IEEE8021X

eap = TTLS

phase2 = "auth=PAP"

(copied from wpa_supplicant.conf)

Similar issue happened in few of the April builds, but warren/cope fixed it in subsequent release.
[HD2 Android SD Development] rfox:
Good news! Bluetooth works with 6.25 version!

as expected! Great!

Another question: I have free space n my 16GB card and was thinking about adding an EXT4 and Swap partition for speed. Can I use a working 6.25 install with data.img and simply create the EXT4 and Swap partitions - or do I have do to do anything special to activate the usage of the EXT4 partition?? Will it simply recognize the new EXT4 and Swap partitions and start to use them?? :confused:

Any tips would be appreciated!

Great Work so far! :D
[HD2 Android SD Development] p107r0:
it will, good walkthrough in faq (see post 1), although I'm not that sure it actually increases performance, it's more like a backup, so may slightly prolong shutdown time, otoh switching builds is easier, as the data from ext4 is copied back to fresh data.img
[HD2 Android SD Development] nygmam:
Just want to point out, 0623 & 0625 BT has worked fine for me, and still working fine. I uses BT everyday, for listining to music/video and calls, plus when I am home, it pairs to my cordless phone, and I use it there too, without having any issues. Those of you with BT Issues, can you post what version you are running, if you did a clean install (And tested BT prior to installing apps) and what you are pairing to.

I can tell you, all work fine for me, even skipping tracks, pausing, and answering/hanging up from calls. Therefore, there must be something else going on, if you are having BT issues, so more information is needed to help you fix it. Also, I will add, you may have to repair, and make the phone discoverable the first time you repair.

A small advice to ALL of you.

Warren and Cope make a very best android ever, spending much of time developing it. So make their time at least bit worthwhile, donate even a little bit, so it will encourage them to stay with us!

They are one of last devs that aren't on the money, but on project itself!

Many devs left to better, newer phones. They are still with us.

Personally I would like to thank you for great work. You are the best.
[HD2 Android SD Development] manoruz:
it's the volume guy again :)

Hi everyone.

So I came across one of the old builds I downloaded long ago - must be one from Dandiest - based on 2.2.1 - the kernel is 2.6.32.15_r2-ga236d1a tytung@ubuntu #5 - the build name is DL DesireZ v3.4Z final.

the volume is just as loud, and has the same quality as the stock Leo Winmo so it got me thinkin - is it sound drivers or jus as the dev's put it 'tweaking' that make it like this - as compared to the other builds - Ds' superram 1.5 all the other one's like JaguarMiui and stuff - none of them quite have that ooompfh.

Hope this helps :D
[HD2 Android SD Development] geenyous:
yeah...

hey, listen up, I got a really cool idea, lets all just start to report the stuff that is working, alright?

Might be some 100+ features plus a few more settings, but imagine, all this positive feedback, nice...

I always thought it was easier the other way around, but who am I? I might have to reconsider... At least no feelings get hurt, especially not those of these poor people that have to actually sit infront of their computer, get forced to log onto xda and read all that (negative) feedback, and the unimaginable pain when they start to type a reply, that nobody asked for and doesn't contribute a bit, boy that must be the horror!

I had an SOD today... unable to unlock : long-press don't even vibrate... but phone was workable : charging was made up to 100%, and through myPhonExplorer, i was able to multi-sync, send and receive mail, check batt status...

But this build works good for me : around 5-10 with data ans sync on (off course, when syncing, it consums more, it's normal), BT works with my car, for receiving even an unpaired device, WIFI wpa2 working.

Without this build, not sure i keep my device...
