Issue - Lost DC-HSDPA after flashing slimkat - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi guys. I have an S3 4g (i9305T) bought unlocked here in Australia and it used to display "DC" in stock form whenever it was downloading data - play store, browser etc. Was also quite fast considering the 3G virgin sim card I'm using. I have since flashed a few ROMs, settling on SlimKat 4.4.2 for the time being (battery drain using pacman was crazy!) Now, the phone is working perfectly and I don't really want to change but I've lost my dual carrier (DC) data connection, having to settle for the much slower 3G, H+ type of connection.
Any suggestions much appreciated guys!

Unable to connect to 3G with Froyo on N1

I live in Japan, and use a Softbank SIM card from an iPhone 3G. For the past few months I have been running Cyanogenmod 5.06 with no issue, Yesterday I installed Froyo with this ROM.
bit.ly/9l3sBM
Everything works great minus connecting to 3G. In japan 2G is no longer used therefore I cannot even make a phone call.
I have checked and rechecked to make sure I am using the correct APN settings.
Any ideas? Could my carrier be blocking it. May it be a problem with the ROM? I did a sum check before installing.
I really would like to use 2.2 as its much faster and the battery life is at least 2X longer.
Thanks,
Brandon
So apparently there was an issue with my automatic cell phone payment, and once my phone disconnected from the network it was not allowed back on. I payed it, and it now works.
Unable to connect to internet with Froyo on N1
Hello !
I just installed froyo on my nexus and i cannot connect to internet (3g, 2g) anymore.
I have the same settings as in previous 2.1 (i asked operator for apn, user etc.).
Every other mobile device i have works with my sim.
Everybody have this issue ? My Nexus is useless without this....
Thanks

[Q] Battery drains 5%+/hr standby on 3G

Hi guys,
I have a Nexus One purchased from Google last year. I only started using 3G this month with Vodafone Australia. My battery drains ridiculously fast on 3G compared to 2G. On HSDPA("3.5G") network with everything off (including data) it uses 5-10% per hour standby. On 2G it drains less than 1% per hour. Using a battery monitor app I can see that 2G draws less than 10mA while 3G draws 25-100mA.
Since on 2G battery life is very good this should not be a problem with any software running in the background. I also tried the following with no help:
- Dial *#*#4636#*#*, set to WCDMA only instead of WCDMA preferred, and select radio bands to AUS BANDS
- Upgrade radio to the latest Korean version
- Force the phone to use UMTS instead of HSDPA network by editing build.prop
I tried both the stock 2.3.4 ROM and the latest CM nightly, but the problem persists. I really want to take the full advantage of 3G and leave it on all the time so this is very frustrating to me. I can use Toggle2G to automatically switch to 3G when screen is on, but that's not what I really want. I know although 3G uses more battery it should not be that dramatic. After all the specified standby time on 3G/2G are 250/290h by Google. With 3G my phone won't last even a day purely on standby.
I also wonder if it can be a problem with the network. My signal strength on 3G is around 2 bars - not particularly bad. It almost never loses signal. If anyone can post a ROM/radio from Vodafone Australia for me to try out that would be greatly appreciated too.
Thanks all!
2 Bars of Signal strength might be one of the reason that battery is drained faster. As the signal is not that strong enough, it keeps searching for stronger signal and results in faster battery consumption.
Personally the radio version '5.12' wasn't satisfactory. I prefer 5.08 version. (Signal strength, speed, battery...)
I recently upgraded from CM 7.0.3 to 7.1.0 RC1 and noticed battery life is much better.
So I am going to suggest a few things you might want to try:
- Downgrade the radio to 5.08
- Full wipe and flash CM 7.1.0 RC1 (or a different custom ROM)
- Try a different kernel (I personally like Cyanogen kernel though)
- Uninstall Task Killer if you have one installed.

Hi zephyr, I previously had CM 7.1.0 RC1 with radio 5.08 and the Cyanogen kernel but the problem remained. I also tried to put my phone near the window, where it has 4 bars signal, but the battery drained just as fast. Thanks for your suggestions though.
I know T-Mobile in the states screwed up something on their network a few weeks back. In doing so, it caused massive power usage on devices when using 3G/4G. I wonder if Vodaphone Australia did something to their network as well...

install current widget, and take logs of your current draw in mA during idle to see what's going on. do an overnight test, then during the day. post your logs.
So I just stumbled across this thread. I've been having the same issue on my Desire, it started suddenly a couple of weeks ago. In 3G mode my phone drains about 120mA. In 2g it drops down to 4-8. I've eliminated all the usual suspects by doing a factory reset (using the CM7.1.0RC but have also tried the latest nightly build), so no apps running in the background, and tried different versions of the radio. I am also with Vodafone in Australia. One thing that I have found is that if I go into Phone Info I can force the phone to make an EDGE connection by choosing the "AUS2" frequency band, and with an EDGE connection I get the good battery usage. But if I choose "AUS" or "AUTO", the phone makes an HSDPA connection and this drains the hell out of my battery.
Just wondering if the OP has had any joy with this?

Try Juicedefender Ultimate, it shuts down data when not in use. I see 1-2%/hr max when used with a good kernel.

Alas it's not the data, this happens even with the data turned off. It's something to do with the baseband connection.
It's not data here either.
This just started happening on my 100% stock unlocked N1 about 2 weeks ago. (ATT)
Most of the time at work I'm on WiFi, yes the signal (cell) is very bad in my office. Has been for a long time, something else is strange.
No extra tasks running, nothing new installed.
Gets piping hot when on the charger - sucks juice like crazy when off.
Checked data log - nothing unusual transmitting...
What sort of area do you operate your phone in? My phone used to drain like mad inside my house (perth- vodafone) and in areas with spotty coverage. In my house my reception would be on the very edge of 3g with no bars and EDGE, constantly switching between the two. Do you have your wifi policy set to on while sleeping? Provided you aren't out and about all day, that would help, though i assume if you've had the phone that long, youd have changed the wifi sleep policy by now.
My wifi is always on - never has changed.
It gets hot at home where there is good reception and at work where there is crap.
I've had the phone for over 1.5 years and this just cropped up.
I rooted my wifes N1 and she doesn't have any issues...

I'm also in Perth, on Vodafone. I get a pretty decent signal strength at home, and it seems to be happening to me wherever I go, unless I'm "lucky" enough to get an EDGE connection. This started overnight, almost exactly two weeks ago. I've been speaking with Vodafone about this at length but not really getting anywhere. Yesterday they swapped my SIM but it didn't make any difference.
Yep, wifi is set to never sleep.
I bought a prepaid SIM card from another provider a few days ago. I only get a UMTS connection with them, but still the current drain when idle is what is considered "normal", 4-6mA.
One thought I've had is that maybe I never had an HSDPA connection before but recent network upgrades have meant that I'm suddenly getting one. Still, 125mA is way too big a drain and seems to indicate something wrong with the phone.
The last test I can think to do is to swap SIM cards with a friend who is on a third network, who gets an HSDPA connection. He has a Nexus One and gets very low current drain. At least that way I can be sure of whether it is or isn't the network. We're doing that tomorrow so stay tuned

Question for Motorola Milestone users on Vodafone New Zealand....

Hi guys, just a quick question for you Motorola Milestone users that use Vodafone's network in New Zealand.
First off, I know that Vodafone NZ does not support Milestone. Only Telecom XT supports it. However, Vodafone does support and sell Milestone 2, so I don't see why this couldn't be possible.
Anyway, I'm currently using Android v2.1 (Eclair). I flashed the New Zealand v2.1 SBF on it, and it works fine and all except it's obviously for Telecom XT, therefore I can't get my Vodafone SIM card to work properly. If I change the network from 2G to 3G, then it works. I don't get full signal bars (4 bars), but I get 3 bars most of the time which is pretty stable so it's not bad. However, if I switch to 2G (to save battery) then I get no bars at all, completely empty. It doesn't seem to be able to detect any network at all when I switch to 2G. Whereas switching to 3G the phone is able to detect all 3 networks in New Zealand (Vodafone, Telecom, 2Degree).
Now the reason why I'm on Android v2.1 is because when I was on v2.2 (Froyo), it has all sorts of problems with the WIFI. It's probably because of the kernel or something, and it seems A LOT of people have the same problem with me on v2.2 as well. If you do a quick Google search on wifi problems on Milestone then you'll understand why. A lot of people have suggested to flash back to v2.1 to fix this, and so I tried and it did indeed work for me. But since the only available SBF for v2.1 for New Zealand is for Telecom XT, now I have this new problem to deal with. It's not a big deal, I can stay on 3G. But if possible, I'd rather not because it seems v2.1 uses up battery more qiuckly, and the fact that using 3G uses more battery means I have to charge often and that's something I hate doing.
Now here's an important note. When I received my Milestone which came with v2.2 (Froyo) pre-installed, it was using Europe/UK I believe. It doesn't have problems with Vodafone's network on 2G at all, however like I mentioned it does have problems with the wifi. But the point is, the 2G network for Vodafone works fine on it.
So ya I'm just wondering, are there any Milestone users out there that flashed a different SBF, say Europe for example, and able to get the Vodafone network to work fine on 2G, while also making wifi work fine as well?
Or, are there any basebands for New Zealand that I can flash? There doesn't seem to be any from what I found.
Oh and here's where I found the SBF files in case you're wondering, here's the link for v2.1 (Eclair):

and here's the link for v2.2 (Froyo):

[Q] 4G, LTE not working / SGS 3 LTE / I9305 CM11

Does anyone know, why 4G is not working with CM11 with SGS 3 LTE version? I just tried to flash another radio, but there was no help found. Or is LTE not available yet in CM11? Is there also any way to have screen rotation in CM11 on desktop? How about battery drain? When I used CM10.1 i could use my phone at least two days, maybe 4 with less use. Not battery life is around one day.
Thanks in advance.

First of all, what version of CM did you use? LTE is no problem generally speaking with CM11. But make sure you have the right APN-settings for your operator. The last nightly I tried was 040828 and with that one I had very stable connection, both on 4g and 3g, and when switching between them.
Battery drain differs sometimes from nightly to nightly, at least it has done for me.

I'm using CM11-20140509-nightly. Now the battery drain seems to stabilized with this nightly. Never had working 4G with CM11. In CM10.1 and CM10.2 it was fine. Is there possibility to have 4G connection problem because my network provider? I'm from Finland and using a network from one company which is a daughter-company of bigger one. The smaller company uses bigger companys network. Could the problem be with national roaming (in 10.2 i had to check the allow national roaming and 4G worked fine, in CM11 there is no such button - at least I couldn't find it)?

The big operators in Sweden does the same thing, with daughter companies for the cheaper mobile plans. But that hasn't anything with national roaming to do, at least it's spposed not to. That should be dealt with on SIM-card level I guess.
My best tip is to verify with your operator what APN you should use for 4G. With some nightlies that hasn't worked automatically, so I've had to mess with them manually to get stable connection on 4G.
4G is working fine for me, currently on the 0508 nightly.
I had to change the APN to match Vodafone's, but it's working.
It's been while since had this problem - it actually is solved. I just had old fashioned SIM-card and operator didn't even offer me new one for LTE and I paid full price of LTE for months. But got new SIM now, but no money back from those robbers. I think they should give proper SIM cards for customers which are working with the connection deal.

4G doesn't stay, always return to H+

Hello everyone,
I just bought a Oneplus 3T and it's a really good phone, but i'm facing an issue : 4G only appears a few time (with almost full bars) but it's just coming back to H+ every time, i mean every time.
Usually i have 4G in that place, even with my old ****y Samsung Xcover 3 and its the same with another phone operator sim card.
What do you recommend for me ?
Thank you very much
Details :
French version
Up-to-date (Android 8.0.0)
Phone operator : Sosh (tried B&YOU)
Fix
*#*#4636#*#* use the diagnostic under phone information and move it to 4g/lte only
I've seen this solution but it's not a real one, no ?
If I put LTE Only, i will not have 3G/H/H+ and stuff if there is no 4G around me, right ?
Perhaps your ISP radio tower is far away, doesnt mean its phones fault
I had some issues with sim. I've to get new sim and 4g service reactivated
Well, as i said before, i was able to have 4G even with my old Xcover3 in that place, so it's not the network provider's fault.
4G is working on my Oneplus 3T, it's just that it's most of the time, like MOST, on H+ and not 4G even if I had 4G in thèses places before...
It looks like he phone auto balance between 4G & 3G as soon as 4G is a little bit weak (even weak, it's still beter than 3G anyway...) and I noticed that sometimes the data are just turned down (nothing DL, charge, but H+ still on status bar).
Im on Oreo stock OOS, do you know if there is any issues on this new version ?
