Same thing for me (BT Teos i5800), battery level is displayed 10% by 10%. That's how it is supposed to be for this device.

Pay attention to battery monitoring software you can download from the market, or task killers. They are both useless (for task killers, an excellent article on the net explains why they should not be used, use this search in Google to find it : "android task killers explained") and for some of them can drain your battery (since they monitor the battery, they induce more CPU work than if they were not used...), or be shipped with adware (resulting in frequent data connections thus battery drain...)

Root first, then use either Titanium to uninstall system apps or do it manually, deleting unneeded apks from /system/app. Both will work, however uninstalling with Titanium updates (removes uninstalled packages) packages.xml file properly.
[Galaxy 3 Android Development] matanb:
Hi!

First of all thanks alot for the answer.

When you flashed your device with the JI2, you didn't experience any of the mentioned IMEI loss or the changing MAC address?

Is there any way I can be sure that everything will work ok and that any of these problems will appear?

Another question - with the JI2 firmware do you experience the the known GPS issues and the incorrect battery indicator?

Thanks again :)

Matan.
[Galaxy 3 Android Development] mehmet1978:
Yes indeed, battery monitoring is useless with the teos, and I uninstalled taks killer too, I noticed what you say with my galaxy S, taskiller drained a lot of battery!

merci, oui, toutes mes tentatives sur le JI4 se sont soldées par un bloquage sur le logo Samsung... je suis finalement sur le JG6, je passerais directement à Froyo quand (si) il sortira!

Merci à tous

Thanks you all

hi elliot, ive been earching all over to ee if there is a foolproof way of rooting and flashing our uk i5801s and have had not much joy either!

i spoke to a phone shop buddy of mine who said he has the softwares to rewite imeis back but he himself didnt know anything more about rooting or flashing thee phones.

i think until there is a 100% success option for our phones and the reason rooting loses the imei and mac addesses, then all we are left with is to try it anyway and keep your fingers crossed that it works.

after all my searching tho, it seems that the est option is to flash our i5801s down to i5800, think someone said better to use one of the earlier firmware versions, and then try rooting them.

ut as everyone seems to keep asking.........if anyone knows the best way for us uk orange i5801 guys, please let us know so we dont brick our phones!!

[Galaxy 3 Android Development] jup007:
I have this happen on quite regular basis with stock JG7 at least. It's not problem with drivers, because even without drivers, the phone should indicate USB connection once you connect it to PC. However, it just behaves as if you connected regular charger. And dmesg show is as modem something.

Anyway, after searching all over the internet, I found the way to get USB connection working again without hard reset. Try this:

1. Dial *#7284#. This should open app called PhoneUtil (there are other ways to get to it)

2. In USB section, swith it to Modem, then switch it back to PDA

3. Exit, and USB should work.

I think for some reason it stars working as USB Modem, because dmesg are same as when I manually switch it to Modem and leave it there. However, on PhoneUtil it doesn't show as Modem, it just behaves like one. Still, it can be forced back to normal PDA mode. Go figure.

possible fix for battery draining fast

Hi everyone,

I have a i5801 branded from Optimus (Portuguese carrier) and with the stock firmware it was impossible to root.

I then updated to the Fixed I5800XXJI2 Firmware in the #2 post, and all went good, including the rooting.

After some days of using and tweaking the phone, everything was doing fine.

But all of a sudden, the battery started draining fast.

I thought what I did before this happened, and I realized. I disabled the visual effects of the UI, and everything came back to normal.

So I guess that the visual effects of the TouchWiz are buggy in this version.

So right now, everything is perfect with this firmware (root, livewallpapers, battery, etc.).

See if this works with you also.
[Galaxy 3 Android Development] Ano59:
Well, everything about Odin is perfectly described in the first post of the topic, which I gave a link to. :D I only added details about things that were not fully described.

I forgot something ; sometimes, the phone puts itself in USB Modem mode and I'm not able to revert it. You can do an hard reset to revert it (but you lose your data) or you can reboot the phone in recovery mode (same thing that when you root your phone ; press Home + Menu + Volume + Power to start the phone (probably Volume down + Volume up, not sure, try different combinations)) and decide to reboot the phone, one of the options that you can select in recovery mode (don't forget that this applies only with flashed firmware, if you keep Orange's one, you can only do a factory reset). This fixes the USB problem (even if it can occur again). A normal reboot fixes nothing, you have to use Recovery mode to fix it, even if you simply use it to reboot the phone.

However, a few posts ago...

I'll try this if the problem occurs again, it'd be faster than a reboot. I'm also using AdbWireless and it works well without any USB connection.

Oh, and I tried the GPS outdoors. It is incredibly slow when you rebooted the phone, I got a fix only after several minutes, but once locked to a GPS signal, you can disable GPS/Wifi/3G/Anything or shut down the screen (not the phone), when you enable everything back, you get located very quickly. I wonder if there's a way to improve first fix delay though.

I've been told that task killers were completely useless and not productive, this was said in this topic too. So I removed my task killer and installed Watchdog.

I installed Swapper 2 to use a linux-swap on my SD card (I formated it with Gparted), it works (even if no one can tell if swapping is useful on Android devices).

I'd be interested in overclocking too. I know you can do it only with a custom ROM because it's a very low level change...I'm using SetCPU to underclock my device when needed and it works fine (I strongly advise you to buy this app, so you can slow down your CPU while screen is off and/or battery is low), it'd be better with some overclock when needed, though.

Now I will try Live Wallpapers. No reason for them not to work though, as some of you said they were working.
[Galaxy 3 Android Development] Ano59:
Live wallpapers don't seem to work. :confused:

I've put needed files in /system/app and /system/lib without any problem, but there's still no "Live wallpapers" choice when I want to choose a wallpaper after a reboot...

[Galaxy 3 Android Development] pp63.1:
Hi,

Tasks killers are absolutely useless, you are right. As someone from the net pointed out (see my post 2/3 pages above), the problem is not with task killers themselves, but with applications which behave badly (frequent 3G connections, whereas some date could be cached, adware applications, applications preventing the device from sleeping [wake locks not released, that was the case this summer with a poorly coded Facebook update]).

So, uninstall / stop using any bad application ; By doing so, you won't ever need any task killer. My Teos-i5800 battery longs 2 to 3 days, compared to just 2 days some weeks ago, when I used to launch many apps, some of them sponsored with ads... I noticed that even when the application was not visible, its ads were fetched from the net (thanks to a background service), resulting from frequent 3G connections, and a device not be able to enter sleep state.

Again, task killers are useless provided all applications on the device have been conceived properly. But with the android market, it's quite easy to download free applications ; many of these applications are poorly programmed, and sometimes their creators don't have a good knowledge of the android platform, so that the apps they create are not respectful to the mobile device context : low memory, slow CPU, battery powered device, network usage, etc.

For the GPS issue, a user named "octy" (search for its posts here) has created an small application which patch the GPS settings so that the fix is done in several seconds. It really works great ! (without using this trick, you would have to dial a secret code to invoke the GpsStatus2 activity and manually enter some settings related to the Assisted GPS). Search "octy gpsopt" on the market, you should find the app.
[Galaxy 3 Android Development] rex4u:
@jup007

Thank you so much for tip. I will try and report back. Thanks.

@amo59

For Live Wallpaper you need to run those commands in terminal emulator.

For GPS use GPSopt from Octy. It works.

Btw, froyo for Galaxy S is launched and is available through kies. Check gsmarena.
[Galaxy 3 Android Development] arnaud_c:
Why nobody use the I5800XWJI4 version ? It's the last one. Is it too much bugged ?

There are gps buggs and not wanted restarts with the last version but it seems to be normal.
[Galaxy 3 Android Development] Ano59:
I already got GPS booster lite from octy. ;) The GPS still takes a while to get a fix the first time.

Thanks, Live Wallpapers work fine now. :cool:

But there's nothing for I5800/I5801 now, right ?
[Galaxy 3 Android Development] pp63.1:
Try using the application named "Gpstest" from Chartcross ltd. I noticed that when doing a cold fix, it was quicker to get the fix from this GPS diagnosis tool (some seconds) ; when the fix is done (accuracy indicator, at the screen top-right corner, shows something other than 0), close Gpstest, and open your favorite gps-enabled app, such as Google Maps, it will fix more or less immediately.

I've tried a good GPS test app I was using, and I tested Gpstest too. Both produce the same results.

I usually do quick GPS test indoors (near a big window) because it's easier for me to do it, but I confirm them with outdoors tests. :p And I just tried again outdoors, I'm still getting no or little GPS signal, and no or a very very long fix. Even if I got GPSopt / GPS Booster Lite.

task manager

yes task manager may be responsible for less battery life, but if we remove it the phone becomes really slow................

i've tried both ways........
[Galaxy 3 Android Development] pp63.1:
Maybe you have a hardware issue, since Octy's app works great on my Teos i5800 (refer to pages 11 or 13 on this thread, when Octy wrote a post to announce his application ; many users answered that it has made their GPS work nice).

Between fix tests, do you switch off/on the GPS ? When I was looking for a workaround to the GPS issue, I observed that it helped to switch the GPS off and then switch it on again between each test to get the fix.

On a typical use case :

- I switch the GPS on (always off, since I don't use it every day)

- I open Octy GPSOpt lite (the free release)

- I open GPSTest and wait for the fix (accuracy showing something other than "0"), usually done within 10 seconds... As good as a good old TomTom ;-)

- I hit "back" button, thus closing GPSTest, and I open Google Maps. The fix is immediately done.

For tests, I'm on my balcony, with a large open view on the south.

For "real life" use, I remember using the GPS either on regular city roads (with buildings, thus reducing the GPS visibility) or on places with more "view" (parks, etc.).

However, when testing behind a window, it's not always as quick to get the fix, but that's the same with a regular GPS (Tomtom, for example). Anyway, since getting the fix "indoor" is not a real use case, I don't mind.

And, by the way, please confirm you have 3G enabled when fixing, since the aGPS (assisted-GPS) gets the fix by querying satellites locations through the network...
[Galaxy 3 Android Development] pp63.1:
You are absolutely right !

The idea is not to consider your phone as a high-performance laptop where you could open apps again and again...

This is a PHONE, with low memory and battery power ! We should use only GOOD, well-behaved applications ; the key is to uninstall any application with advertisements or inefficient network connections (connections even if the app is no longer visible ; this is often the case with ad-sponsored apps ; connections results not cached, etc.).

Since I no longer open TF1News (a news info service provided by a French TV channel) or Facebook (default release or any update), I have 1 day more of battery power !

I prefer to rely on web-browser equivalents (Google News, Facebook Touch mobile website) ; they are as efficient, and sometimes bundled with more functionnalities.

Sorry for my bad English :)
[Galaxy 3 Android Development] pp63.1:
I totally agree, try with and without task-killers for some time (a week ?), with sensible phone use (some calls, some sms/emails, and favorites applications, such as Facebook, etc.).

By the way, something could be used by many people, but it does not always imply that it's a good pratice ;-). Think of smoking...

Again, a technical approach proves task killers are useless. The Android VM has been designed to manage application lifetime, and opened applications waiting in the background don't eat any CPU... The only thing draining the battery is network/wifi/gps use ; a careful choice of well-behaved applications (no ads, no auto-updates/realtime notifications if not required) and reasonable use is the only trick to extend battery life.

Reading any Android-developers book clearly explains how application lifetime is handled by the system. Just have to be curious.
