3G in Europe / Asia

I am planning to purchase the Samsung Galaxy SGH-T679M from Virgin Mobile Canada and I was wondering if the phone will support 3G ("H") in Europe & Asia?.

3G radio frequencies in Europe, Asia & Australia are different from the 3G frequencies in North America. I purchased a Samsung Galaxy Gio S5660M from Bell Canada and it did NOT support 3G in Europe & Asia. I was able to only get "E" (edge) in Europe & Asia with the Gio S5660M last year.
[Samsung Galaxy Exhibit 4G] Irate Iguana:
It all depends on the frequencies used in europe/asia and the phone's support. According to http://www.worldtimezone.com/gsm.html it seems like most if not all European countries use 2100 for their 3G. Check if the phone you're buying supports the 2100 spectrum.

[Samsung Galaxy Exhibit 4G] utsc:
Thank you. Yes you're correct 2100 is kind of the standard for 3G outside of North & South America. Gmarena says that Samsung Exhibit II 4G supports HSDPA 850 / 1700 / 2100 / 1900 so it should work. However the retailers site does not mention HSDPA 2100. Also what is sold in Canada is SGH-T679M

3G not working in Europe

I actually own a T679 and I live in Europe (Romania, Transilvania), so I can tel You for shore, that it does not work on any standard European 3G network.

In Romania there are 3G networks operating on 2100MHz, different channels as in US.

There are also 900 and 1800MHz networks. These are GSM/3G.

The GSM part works beautifully on 850/900/1800/1900MHz (EDGE/GPRS).

In Australia 3G should work on 850MHz...

You are right Whyzor, credit goes to Pasquale Lodise (lupohirp) from Italy.

I tried it on my friends P500 with ICS (CM9), and the camera works for still pictures and preview.

Issues:

-no motion pictures

-no tap to focus (it focuses on center of image)

-no panorama pictures (this may be related to the camera app)

There is also a camera fix on http://xdaforums.com/showthread.php?t=1626281&highlight=lupohirp+camera witch I did not tried yet.

Be aware that the P500 has an older sock with a diferent instruction set, and it might not work at all.

Hope this might help Tim1928 .

CWM Backup/Restore Revision Control

I am using the latest version of CWM, and use it to make frequent Nanroid backups, as I switch between CM9 and Stock 2.3. The file naming convention (date&time) results in confusion as to which backups are CM9, and which are 2.3! I tried to change the name of the backup files to better reflect the OS but that resulted in a MD5 checksum error. I have had to keep a written table of what is in each backup. Is there a better way to manage this?

[Samsung Galaxy Exhibit 4G] Willielf:
Wait, does making nandroid backups allow you to keep your apps and data between switching the rom?? Sorry I'm kinda noob at this..
[Samsung Galaxy Exhibit 4G] KemikalElite:
Only change the folder name for that nandroid backup, not the files inside it. Do not use spaces, this can cause errors.
[Samsung Galaxy Exhibit 4G] kingdavidd:
No it just backups up your current install so you can flash to another rom and then restore the backup when you wanna go back.

[Samsung Galaxy Exhibit 4G] Faultyy:
Yes, when you make a nandroid you make an exact copy of whatever your phone is at that time. So that would include things like your boot image, apps, data, even your homescreen will look exactly the same when you restore a nandroid. It's a great way to switch between roms.

I have not tried it yet.

I needed the camera (reliably) for my work, so I switched to Rebel 2.1.

I really-really miss ICS, but I had no choice.

Maybe Sunday I will have time to flash ICS and try it.

The fix is working on the P500. I think it might be adapted to our camera driver to.

How do you like it now? I'm always a little cautious when buying batteries that come from ebay and such. I could care less if the battery doesnt last as long as the original (In terms of charging cycles) while giving me a longer battery life per day. I just don't want these things to damage my phone.

The price is good, cheap good batteries, was just wondering how you like the battery now after using it for a bit.
[Samsung Galaxy Exhibit 4G] airwickkk:
I was considering buying an OEM battery on ebay, because there are some times where in extra battery would really come in handy. Please, do tell how you like your 3rd party battery!:D

[Samsung Galaxy Exhibit 4G] dennis96411:
Well you'll have to be patient, takes about 2 weeks to ship because it comes from China. :p

It's been 11 hours now, still 40% left. I've been using my phone all day, so this battery is actually pretty good. When I first charged it, it didn't last very long; the second charge lasted much longer, which made me decide to just use this battery as my primary battery.
[Samsung Galaxy Exhibit 4G] Willielf:
Just wondering, how long have you been using your battery now? Because I've heard that bad quality ones usually start to degrade later.
[Samsung Galaxy Exhibit 4G] dennis96411:
Only about a week, I'll keep using it and report back.

Well I downloaded their camera fix which seemed to be just an apk that used a script that cwm 3.x.x does not support so I took the apk out and installed it which was camera.apk didn't seem to fix anything but there camera may be the same as ours, I am only saying that on the basis of ours is a 3.5 megapixel and theirs is also.

[Samsung Galaxy Exhibit 4G] stab244:
Huh just noticed this issue where my ringtones changes to use unknown ringtones after I rebooted my phone. Not sure why. Maybe because it's stored on the external SD card and it doesn't scan it.

Was there ever a temporary solution to the 10% an hour battery drain?
[Samsung Galaxy Exhibit 4G] kingdavidd:
I wasn't aware of this issue? I have been running this rom since Jocala compiled it and never once had that.
[Samsung Galaxy Exhibit 4G] jgrinst1:
For those still showing battery problems, you need to re-calibrate your battery, which you should do every time you change type of ROM.

1. Plug in charger and charge to 100%.

2. Unplug charger and reboot to CWM recovery.

3. Choose Advanced > Wipe battery stats and do it.

4, Reboot to Phone.

5. Let run down completely and turn itself off.

6. Recharge to 100% without using it.

7. Go. Use normally.

You should see a significant improvement!
[Samsung Galaxy Exhibit 4G] Willielf:
What do you mean about the 10% per hour? Is it on standby? Cuz I don't have that problem..

[Samsung Galaxy Exhibit 4G] kingdavidd:

[Samsung Galaxy Exhibit 4G] strogg:
I did that first thing a long time back and it did nothing but make the drain very linearly. Here's some more report back. Magically (I did nothing) it went to 5% an hour. it was an improvement, but i still can't get 24 hours out of a charge. Turning off wifi notifications did practically nothing. This is still a problem that needs to be addressed, since I was able to easily get 50 hours out of a charge from using the xquizit rom. Now, again, i get about 20 hours.

Also, is it normal that I can't turn on the phone while it's plugged in? I have to unplug the cable to turn on the phone from dead off. Otherwise, it just shows me the battery charging animation.
[Samsung Galaxy Exhibit 4G] danny8:
I don't know if it is normal, but I also have this. I cannot reboot while it is plugged in either. Just to be clear I am talking about charging my phone via USB cable from my desktop computer. I have also seen my phone spontaneously boot (!) from powered-down state when connected to the computer. This happened when I booted the desktop computer.

You might clarify if you are talking about USB charging or AC adapter charging. If it even makes a difference. I'm going to test it with my AC adapter right now.

Edit: my Exhibit II will not boot while it is being charged via AC adapter. It just ignores my long-presses.

I suppose there might be variance in the charging components used in production runs. For all I know, regulator chips have their own firmware or primitive logic.

[Samsung Galaxy Exhibit 4G] interessant:
Confirmed something that happend in the past but wasn't sure last time. When leaving the area with service into an area with low power service the hunt for signal will warm up the phone significantly and drain battery fairly quick. Turning on airplane mode will fix it but it will also disable you from using wifi at the same time.

Tried various options of having just wifi on without service hunt and it wouldn't work.

I also noticed a nexus s with wcdma only option enabled was able to retain service in the same location on same provider.

Without wcdma only option the hint would take longer and wouldn't remain locked as moving through the low signal area.

Its unfortunate that we can't completely separate wifi from low signal hunting whether 3g data is on or off..using airplane mode or not. Its also unfortunate that the wcdma only option or any other band option cannot be enforced through the kernel. I'm fairly sure this is a rom coding issue as opposed to available feature options in the radio chip set.

I've been using my phone the whole day in airplane mode with Wifi on.
[Samsung Galaxy Exhibit 4G] Willielf:
I just tested it, and the volume will work if I go over the 60% mark on the volume bar. It's kind of weird, because that would usually work for earphones.

Edit: yeah, I just tested with headphones, and it has no problems going past the 60% mark.. Does the phone detect the audio outs differently for each plug?
[Samsung Galaxy Exhibit 4G] interessant:
I wonder if it's the hunting for gsm signal that interfered with it. The wifi status would be on but it would not show any wifi networks available until airplane mode was turned off.
[Samsung Galaxy Exhibit 4G] strogg:
Yes. I get the problem in Pandora. I haven't tried with headphones yet. Headphones and receivers do have different impedance ratings, though. Maybe rather than sensing the physical presence of the connector it senses the output impedance, and if it's too high (usually 600+ ohms for a receiver) it may as well not be plugged in? Just conjecture.

But yeah, in Pandora, it will randomly seem like I just unplugged the cable. Audio will cut to the phone loudspeaker for a split second before Pandora pauses. Could be a ROM coding issue? I've never had the problem before.

Enabling European 3G frequency band (2100)

Does the SGT-T679M have to hardware (radio chip) to operate in the 2100 frequency band? Is it possible to Enable European 3G frequency band (2100) in SGT-T679M by flashing the firmware with a European version?

According to gsmarena this phone supports 3G Network - HSDPA 850 / 1700 / 2100 / 1900 . However the phone specification in gsmarena is SGH-T679 and NOT SGH-T679M . I believe the "M" version is an American model so I am not sure if it has the same hardware as SGH-T679 and if the custom service provider software has blocked the 2100 band but I could be wrong. Hence I the above question from the experts.

Thank you for your time.
[Samsung Galaxy Exhibit 4G] TheGeekRedneck:
No offense intended at ALL, but I wish people would stop giving out this advice. Wiping battery stats (ie deleting batterystats.bin, which is the same thing that the option in CWM does) has absolutely zero... ZERO effect on battery life. It also has ZERO effect on the battery life that Android shows you in the status bar.

The 'battery stats' (better known as batterystats.bin) is ONLY used for the per-app battery usage tracking in Android.

But don't believe me, believe it right from the horses mouth:

Here's the deal. It doesn't change the physical way the phone or the battery work, just the way that the operating system is reporting it. Yes, the file is deleted in certain circumstances when the phone is nearly charged, in which case this won't help. In the case where people's charging habits don't coincide with that possibility, this may help them out.

In my case, after doing this, Android reported a 30+% improvement. Up from 10+ hours to nearly 14 before expiring.

So, that is more likely the current baseline for this ROM. People who turn off Wifi or total cellular data (or both) could get much better battery usage. That's where Juice defender comes in and is good at. However...

When I am at home, I have both Wifi and data radios going but not GPS or Bluetooth. I don't need mobile 3G data but I do want to get Google Voice push notifications, which rely on a data connection (not sure about cell), so I can't turn on airplane mode. IIRC, you should be able to turn off 3G data radio without turning off cellular (GPRS) so that's next on my list.

So, obviously, this is still a work in progress. I've just started using this ROM, so I apologize in advance if this is a waste of time.

It is Mixer ICS theme (props to T679noob for the suggestion) with minimalistic text "icons".

The Mixer ICS theme is installed from a downloaded .apk. It has (at least) one bug, with the alarm display, but it has a really nice look. For CM9/ICS only, I think.

(In fairness I should call it an incompatibility, not a bug. When I applied the theme it warned me about "missing assets for this screen size" but I clicked "apply anyway".)
