Go into Wireless and Networks, WiFi Settings, hit the Menu button, Advanced, WiFi Sleep Policy, and choose Never. There ya go, WiFi stays on when the device is asleep. This should be the default on all Android devices, but it's not.

WiFi uses far less battery than 3G, even if left on while sleeping, and of course it doesn't burn your data plan.
[Galaxy Tab General] Beards:
Thanks... Okay, that's got rid of that problem.

Anyone else have any opinions on whether or not to use the Tab with a SIM Card?

I can justify getting the Tab but I can't justify buying another SIM Card.... unless the advantages outweigh the costs.
[Galaxy Tab General] Jyveafk:
Get a 10buck data only card and leave it plugged in. If you think you're going away for a bit, pay 10 bucks to re-enable it for that trip and be done!
[Galaxy Tab General] Beards:
Don't think they do a Data card for that price in the UK.

You can get a £10 SIM Card from the likes of T-Mobile but it's still £10 every month regardless of whether you use it or not.
[Galaxy Tab General] george1983c:
Hey I don't have a galaxy tab used to have an alas before it bricked. Anyway there is no need to buy a simcard just Google advisable.apk. Its a mod that allows you to establish an ad-hoc connection to pull internet from a mobile or computers ad hoc connection
[Galaxy Tab General] Beards:
Intrigued, I did as you said Googled 'advisable.pk' and the results came back..... Nothing.

Are you sure you have the name correct?
[Galaxy Tab General] foxmeister:
Not so.

There are plenty of PAYG deals doing around that allow you to do.

For example -

3.

T-Mobile do a £2 per day deal which is quite good.

My personal favourite would be GiffGaff if there was any kind of O2 signal where I live.

EDIT - actually, my new personal favourite would be TMo 6MONTHWEB for £20, which gives you 1GB a month for 6 months for only £20!

As far as I'm aware, all of these are effectively "pay as you play" options. If you don't need to use the internet from one month to the next, just don't use the SIM, and when you need to ensure you have enough credit to buy an add-on/goody bag whatever.

Regards,

Dave

Hi Beards

FYI, T-mobile US no contract Tab comes with a SIM card unactivated.

Wifi works just fine in this configuration. It also works without SIM card however you get a message Emergency calls only.

Cheers
[Galaxy Tab General] slimdizzy:
I have a sim for my tab. $20/month Bell Flex plan is cheap enoigh and I can cancel at any time and just tether with my desire. Wifi at home but HSPA everywhere else. Once the roms start coming out ill unlock amd just use my telus sim with a BT headset for calling. Using the bell sim allows me to text from my GT and I love that option.
[Galaxy Tab General] XavAcid:
I didn't put sim in my Tab at first, but now I got one and a tiny dataplan to go with it, since I mostly use wi-fi and work and home.
[Galaxy Tab General] jay_jay_n:
Really wifi uses less battery? So is there a way to fully disable 3g and use wifi only , thinking of just using a phone as a access point
[Galaxy Tab General] Croak:
Airplane mode and then WiFi back on works.
[Galaxy Tab General] deez1234:
I believe you can use the XDA Superpower app.
[Galaxy Tab General] foxmeister:
Switch to GSM only which will leave the phone operational, or airplane mode with wifi on to completely switch off cellular radio.

Regards,

Dave
[Galaxy Tab General] Beards:
Interesting comments.

I was not aware you could obtain a SIM card with Data for such a cheap price.

However, it's nothing really to do with the money, I'm fortunate to be able to afford an additional card without even thinking of any financial consequences. I am though more interested in hearing how you use the Tab and how you get around the problems.

Having said that I know what will happen; I'll get the Tab and then end up purchasing another SIM Card with all the trimmings for something like £15 to £20 a month just for ease of use.
[Galaxy Tab General] jay_jay_n:
this is wierd i have it set to never sleep wifi but it seems like everytime the screen is off the wifi does sleep, i am using the modified wpa_supplicant to connect to my ad_hoc...
[Galaxy Tab General] fnakfhe:
how much did bell charge you.

i wanna get one without a data plan just out right.

what options do we have?
[Galaxy Tab General] Croak:
Bell charges $649, but also requires you sign up for at least one months' service (minimum $20, but they bill for that), and there's the $35 service fee (which they may charge on the spot, or they may bill you for, or even waive).

Cancel the data plan as soon as you leave the store, you're still out $55+tax but have a month's service to show for it. Or keep it on for two months and get a $50 credit, which after taxes means you get those two months for free, and THEN cancel.

There are no other options, though you may be able to talk a Best Buy or Futureshop flunkie to sell you one outright with no activation, but that's very hit or miss.

i have got this problem on all my roms

is this a normal problem and i there a solution?
[Desire HD General] Potential Buyer:
Hi everyone;

I am almost decided on doing away with my SE x10i for Desire HD. But I also have HD7 and iPhone4 on my mind.

My basic requirement is a cell phone with a good video quality (to watch movies/videos) and good audio quality (to enjoy music on). From what I have heard DHD has good video quality, worth watching videos/movies on, but I want to know how good is DHD's music quality on Head Sets? (I know it isn't much impressive with the speakers).

I really used to love the audio quality on my iPhone3G. Later I bought x10i which basically is not a good device for music. The reason I don't want to go for iPhone4 is small screen. To simply put how good is DHD compared to iphone series when it comes to music? & also is it any better then x10i?
[Desire HD General] moraal:
For me, the DHD has great audio quality, I use a pair of Sennheiser CX500,very cheap and excellent quality, comparable to Shure plugs (so I've read). As a music player I use PowerAmp and together the sound quality is very good, even with the stock player. Music quality is important to, but I'm not an audiophile. Before I had a Samsung Omnia HD and SE W960i walkman phone and the DHD definitely has the best audio quality.
[Desire HD General] vimto25:
Audio is better than iPhone 3gs
[Desire HD General] Potential Buyer:
Thanks guys;

I think DHD it is then.

I just pray and hope I don't regret buying it like I did with x10i.
[Desire HD General] XmUrF:
The sound should definitely be better than x10, but I don't think it will be better than iphone. Check the review on "gsmarena.com"

They talk about stereo crosstalk problems with headset on. The frequency range is good, but according to them the stereo crosstalk with headset is quite bad. I myself haven't listen to music that much and anyway I use the original HTC headset that comes with the phone. It's probably not the best option so can't really judge the audio quality, but for me and my needs it's enough.
[Desire HD General] hudlqs:
I tried using my Sony XB700 headphones, and i must say that i'm very pleased with the sound quality! I'm almost about to ditch my Zune HD :D
[Desire HD General] Robboftw:
While people are moaning no end about the speaker (which is not really that bad at all), the headphones quality (tested with the standard HTC headphones) is really impressive.

I would imagine its second to none with some decent headphones. Impressed.
[Desire HD General] Potential Buyer:
That would definitely be a disappointment, but if it is any better then the x10i I think it would do. X10i simply $uck$.
[Desire HD General] Luki3d:
After I saw review on gsmarena, I'm worried about sound quality too. I guess digits don't lie, but I still can't believe in such poor result. Too bad that I can't test it anywhere, it's really impossible for me to find a place where I can put my hands and ears on DHD.

So any opinions will be helpful.
[Desire HD General] YumYumHD:
Actually while being unsatisfied with the external speakers, I'm really amazed by the sound quality through headphones/earplugs.

I use Sennheiser CX300II in-ear plugs, and can't say otherwise that I'm really pleased with the soundquality, especially compared to my old N95.
[Desire HD General] Potential Buyer:
Looks like we both are on the same boat now. Only way is to actually buy DHD and check it out. In my case I may have little to lose as I am sure it has better audio quality then x10i. Even if not it is over all better then x10i. I'll update in few days when (or if) I get DHD.
[Desire HD General] Noisy1:
I too was impressed by the stock headphones that came with the phone, although they were lacking in bass they were very clear. I've got a pair of Sennheiser HD 485 home theater cans which i've tested the phone out with and i'm very pleasantly surprised, i've tried both stock music player and power amp and both sound great no complaints at all.
[Desire HD General] noobdeagle:
one of my friends got a vodafone one here in aus ....meanwhile im still waiting for my sim free one from handtec :\

anyway they used to have an iphone and both the DHD and the iphone sound average to me the DHD is probably above the iphone when it comes to clarity and EQ modes let you change it more than you can on the iphone where your limited to premade presets which just are ...meh the dolby really adds bass tho but still seems a bit artificial and sometimes the mids seemed a bit to harsh,

but on the whole both iphone and DHD have nothing on my cowon S9 so im not ready to stop carrying a dedicated player just yet, once my DHD arrives :P

headphones i used were Jays Q-jays dual armature IEM's

so yeah its ok but its not as good as dedicated devices :)
[Desire HD General] rossysaurus:
just listening to some test tracks now with my RE0's, ultrasone 780's and sennheiser mx760's.

its not bad, but my god it has A LOT of bass. the mids sound thin and artificial, but the treble is not too bad. its certainly better than the 2nd gen ipod touch, and i'd put it close to the iphone 4. if the mids didnt sound so....cheap it would be as good as the iphone 3GS/4.

it could sound better but its not bad. dropping the mids helps slightly, which can be done in power amp but not in the basic android player. the rock EQ preset helps a bit though. with this it sounds very close to the iphone 4.

dolby mobile sound is TERRIBLE. sounds like you've swallowed a sub woofer and put your head in a cardboard box. SRS is just trying to deafen you with harsh horrible artificial sound. avoid them two.
[Desire HD General] NZtechfreak:
I think what you're saying marries up nicely to the GSMarena review.

To the OP: If sound quality is very important to you, and your ears can actually tell good sound quality, then I don't think this is the handset for you (unless its considerable other benefits outweigh that for you, but from your original post I'm not sure they do).
[Desire HD General] dr.m0x:
I did regret buying an x10i, and I don't regret buying this. Great phone. Speaker is a little lame but very nice with headphones.

| Sent from my LeeDroid Desire HD |
[Desire HD General] Potential Buyer:
Well ... all I want is sound quality that is at least equivalent to my old iPhone 3G, if not any better. That's all. I am not looking for a dedicated music player on a cell phone. I would go for iPod if I were. Would cost me much less.

I am also looking for good video quality to watch videos/movies on while traveling. This puts DHD on top of my list. Other alternative for me is iPad - but the hectic it carries when it comes to converting videos files to mp4 just kills it for me. Plus I want something that fits into my pockets.
[Desire HD General] XmUrF:
Well, honestly, .mp4 files play and look quite good on dhd. However beware, not everything plays OK with the internal player and rock player is good only for .avis. Anything heavier and it struggles.
[Desire HD General] Potential Buyer:
Well as long as it plays .mp4 and .avi in good resolution I have no issues. The x10i plays DVD quality files in .mp4 format pretty well, so I guess DHD can do so also(?). HTC has been promoting the device as good for movies.
[Desire HD General] XmUrF:
It is good for movies. With Rock Player you can play any .avi file (well at least I haven't found one that can't be played). mp4 files however you can play only with the default player (with rock player's software decoding it's unwatchable) and the default player doesn't play every .mp4 file out there.
[Desire HD General] Luki3d:
I'm waiting for your impressions. :)

Also, guys could you go to youtube, find any video with the stereo test and tell us is that "nearly mono sound" is a real problem, or it was just an issue with that particular device gsmarena had tested.
[Desire HD General] Potential Buyer:
I might get the set today. Will update you.
[Desire HD General] NZtechfreak:
I would have thought if movies were also a priority with music then the Galaxy S would be a better fit - it has much better sound quality, a better screen, inbuilt ability to play many movie formats.

It has its own pros and cons, but for what you've shared so far of your needs its better.
[Desire HD General] XmUrF:
I don't know about the sound, but the screen superiority is very subjective. Dhd has larger screen and although samoled has better contrast I think sLCD is OK as well. Better view outside and for movies the higher contrast is painful ( when you watch with little or no light).
[Desire HD General] NZtechfreak:
The true blacks and contrast make it much better for movies (the contrast is not the problem for low light viewing, its the brightness), but its better for playback support too with its inbuilt player, and it has a better battery life (so you can actually watch a movie whilst not attached to a charger). Take a look at the GSMarena review (in fact pretty much every review on the DHD) - they all say the screen is alright, but distinctly inferior to the Galaxy S. I don't think anybody has suggested its better in outdoors conditions either, I think perhaps you are confusing the Galaxy S Super AMOLED screen with previous generation AMOLED screens, which did suffer by comparison to regular LCDs outside. Screen quality is subjective, but the screens are far enough apart that nobody will tell you the DHD screen is better for movie watching.

Thats not to say that the DHD isn't a great device, but for music and movies its distinctly inferior to the Galaxy S, I don't really think its possible to make a legitimate case for the DHD being as good in those arenas. It may still be a better device overall for a particular user, and that may include the OP here, but if these areas a really priority use-cases then the choice is reasonably clear I think.
[Desire HD General] XmUrF:
You are right, it's the brightness. And as a matter of fact I did read reviews that preferred dhd's screen over samoled. Yes it's true samoled has very vivid colours, very crisp image. However I do insist that on low light it's painful to watch. At least for me. And when you reduce the brightness it's harder to see compared to slcd. And although my experience is based mostly on amoled, I doubt it differs that much from samoled. And of course bigger is... Just bigger :)
[Desire HD General] SupremeBeaver:
The problem with Super Amoled, or Amoled is the pixel arrangement. Simply because of that i prefer LCD screens.
[Desire HD General] Potential Buyer:
I got the DHD today. My initial review is that it has good audio quality on head phones. Certainly better then the x10i and may be close to iphone (may be). The reviewers complaining about low sound probably got a wrong set or they confused x10 with DHD.

In the video quality department, unfortunately I found x10i better in quality. DHD pixels aren't good on DVD quality .avi file. But I think it is still good and I can get used to it.

In addition, it is the most handsome phone I have ever seen. What ever the pros and cons (except the phone breaking up or totally stop working), I do not regret buying it and turning in my x10i.
[Desire HD General] NZtechfreak:
I agree, I don't like pentile subpixel matrix either (although I love Super AMOLED), but it only really makes itself known when viewing text. It doesn't matter at all in video watching.
[Desire HD General] l0w:
Ipod/iphone 3 is vastly superior for listening to music compared to dhd.
[Desire HD General] JohnMJH:
I'm trying Rockbox player now. There is a setting allowing you to increase the "stereo width". I find that reduces the stereo crosstalk problem on DHD.
[Desire HD General] erichung_13:
A 4inch screen for movies and DOLBY certified speakers with SRS. Im pretty sure this beats the iphone 4..
[Android Q&A, Help & Troubleshooting] python08:
Hi everyone,

I'm currently trying to compile Android 2.2.1 for my HTC Desire. My question is simple : how do i add Superuser and su to my build ? I managed to add Superuser but su isn't included... my android/system/extras/su/Makefile looks like that :

ifeq ($(BUILD_ORIGINAL_SU),true)
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES:= su.c su.c activity.cpp
LOCAL_C_INCLUDES += external/sqlite/dist
LOCAL_SHARED_LIBRARIES := liblog libsqlite libandroid_runtime
LOCAL_MODULE:= su
LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_STATIC_LIBRARIES := libc
LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES)
LOCAL_MODULE_TAGS := debug
include $(BUILD_EXECUTABLE)
endif

I took the code from Cyanogenmod.. but it doesn't work ...

Thanks in advance for your help,

Renan.
[Android Q&A, Help & Troubleshooting] Gene Poole:
su.c didn't produce any output? Was there an error in the build?

You could probably fake it by just copying sh to su and giving it SIUD (root:root 4755) permissions
[Android Q&A, Help & Troubleshooting] python08:
Thanks for your reply.

I tried to compile with different Makefiles (stock, modified, cyanogenmod one) and different files (su.c or su.c, su.h and activity.cpp) but there's no output :/ I don't see su in /system/bin or in /system/xbin... And when I load my ROM on my phone, Superuser doesn't work because there isn't su. I tried to flash superuser.zip but there's an issue with the symbolic link I think.

I found a guide who explaned how to root aosp for motorola sholes but this method (the one I used) doesn't work for me..
[Android Q&A, Help & Troubleshooting] Gene Poole:
It it's just a matter of the su executable, one from any android build would probably work. The command line tools are all ELF ARM-NONE-EABI.
[Android Q&A, Help & Troubleshooting] python08:
It doesn't work at all...

If I remove su (chainsdd's android_system_extras) and add the binary, then create symlinks, it doesn't work.

su causes an issue when I'm building source:

android/system/system/extras/su/su.c:149: undefined reference to `_mktemp'

But it's strange... when I build without it and then re-add the source, all is ok. But on the phone, I get a seg fault when I try to run su...

What's wrong ? :/
[Android Q&A, Help & Troubleshooting] Wing_Zero85:
I'm also interested in this...
[Android Q&A, Help & Troubleshooting] python08:
Look at the sources of my ROM : http://github.com/python08/android_system_extras.git

Look at su/Android.mk

You will understand the problem ;)
[Android Q&A, Help & Troubleshooting] arshcaria:
I dont know if it is too late to answer you~

Be aware of the following:

LOCAL_MODULE_TAGS := debug

It means this module is included ONLY when you are building an "eng" or "userdebug" version.

If you build your android with "user" this module will not be included.

Try change LOCAL_MODULE_TAGS to "optional".
[Optimus One, P500, V General] uitem:
sometimes on Optimus I cannot access the GPS, any program doesn't get a fix and the very good GPS test app is not showing any satellite. This is outdoor where some minutes before the GPS was working perfectly.

I fixed it once by restarting w/o the SD, then putting it back in, but it doesn't always work. Sometimes it helps to remove the battery, but I can't find a sure fix for that.

It is annoying also because there's no way of knowing why the GPS is not working.

Hmmmm.... U can try this tips to access the internal gps test menu @ link: goo.gl/ZFs6D

Looks like you haven't understood yet how patch/diff files work.

This message:

drivers/media/video/msm/msm_v4l2.c:337: error: expected expression before '<<' token
drivers/media/video/msm/msm_v4l2.c:343: error: expected expression before '==' token
drivers/media/video/msm/msm_v4l2.c:346: error: expected expression before '>>' token

tells me that the file msm_v4l2.c is broken between lines 337 and 346. You couldn't "put" the resulting kernel in your G1 even if you wanted, since the kernel doesn't even get built due to that error!
[G1 Android Development] michael-knight:
Okay, I thought about it for a while, and I couldn't believe that it was the patch file causing this to happen, because the patch file is adding support for the USB Host function, why would it mess with video?

Anyway, I compiled the kernel 3 times after that. I compiled it the way it was meant to be compiled; 2708 config with no patching which obviously worked with little error (although it was surprising to see how many there were anyway), I patched it then I compiled it using the 2708 config to see if it was the merged config at fault, and it was.

So what I decided to do after is merge the two config files again but be a little more careful not to merge anything that doesn't have to do with USB Host.

After I did this, I used the newly merged configuration file, compiled itand it worked!

There was probably about the same amount of errors as the original.

Moving on, what do I do next?

I'll attach both the output text when compiling the original kernel and original config file, and the output text when compiling the patched kernel with the merged config file.

Also, what does "module" mean? I was given many options to compile many device drivers (I'm assuming? that's what it looked like) with three options, N/m/y.

I'm also assuming that N is capitalized because it's default, but I decided to choose m for most of them, because I thought I might use them, and module sounded like a compromise between no and yes.

Maybe what I'm really asking is, where do the modules get stored?
