How do you test modem ? - Galaxy S III Q&A, Help & Troubleshooting

Hey, I'm new android user here
I want to know how do you test and compare modem ? By manually look at the signal strength ?
Is there any apps to benchmark it ?
I'm just tired flashing and downloading different modem but not sure which one is the best. Thanks !!

NO. Manually only, flash modems from here http://forum.xda-developers.com/showthread.php?p=28033515 , one by one every couple of days. Watch your signal bars and run few speed tests. Strong signal doesn't mean fast data. It's all depends where are you and who is your network provider. Have a fun

You have a very old Gingerbread baseband from september last year. LPS works excellent, I'd give it a try.
Downloading LPS now from this thread
http://forum.xda-developers.com/showthread.php?t=1131950&page=105
does Vodafone has any different modem for SGS2?
Still facing same issue upgraded modem LPS Its still the same.
Strange thing is Use 2G network and Data Enabled is unchecked itself whenever I had this problem.

There are a larhe number of modems .
Start with the last one and work your way back .

Best way to find a good Modem is testing them all.

You need a computer and a thing called search and you look on XDA thread for Modem post with flashable modems .Like most stuff its found in development .
But you would do better to read the basics first .

O2 UK modems

Any recommendations for a modem to use with o2/giffgaff ??
Sent from my GT-I9300 using xda premium
I'm just using Omega rom with the modem from that and it works beautifully, always get signal and strong internet speeds. Much better than my S2 when I used to flash new radios
A friend of mine has a O2 phone and i think he has XXLE5 on it
You cannot be recommended the best Modem. Even from people on the same network, they are not in the same are, going to the same places you go.
You have to work out which one is best for you. There is no right answer.

Hsdpa/3g switching issues

First off phone is stock and un rooted.
My issue is that the phone will switch to 3g or E so much and then often not switch to H when I use an app requiring Internet so the app won't load anything. Anyone else have these issues or is there a fix? I'm in Australia btw.

If your phone is unrooted, there are limited things you can do to solve it. If it is rooted, you can actually try to flash different modems for your phone and see which one works best for you or just find out from this forum what modem is best for your carrier.

Sorry, I have looked around and you can actually flash modem through Odin if your phone is unrooted.
Oh really?? Thanks for letting me know, I haven't messed with flashing before so I doubt I will now haha i might wait for official updates...

Most official modems for my region are terrible, I'll bet your's aren't better. Asian modems have a far greater stability, especially the DXLF3 modem.
You can't do anything wrong when flashing a modem. Just get Odin, head to the modem collection thread, pick your modem and flash away.

Sounds like antenna ping-pong. Basically that means that your carrier keeps moving you from one antenna to the other.
Alternatively, check if you have any Proxy configured in the APN settings as slow proxies can cause the same issue: go to Settings->More->Mobile network->Access point names, choose the one reading 'internet' (or something like that)
Check if any Proxy server IP is filled in. If yes, write it down and delete it from the profile. If Internet doesn't work, reconfigure it.
If it's better, congrats
Oh really! I didn't realise the Asian modems would work well in Australia thought they would be specific to region, obviously not! I will try the flash if nothing else works..
I checked in the settings like u asked but there is nothing under proxy? Should here be an ip is that the possible problem?

Wcdma only still switches between 3g and H, trying it now. So it wouldn't make a difference would it?

there is still difference in term of speed between 3g and H. if you want consistent H+, change modem to BWLE5, if you not in LFB based rom.

with this modem, your phone will go straight from 3g to H+, it doesn't even know H anymore. lol. try it to feel the drain on your own.

Try it. If it doesn't work flash back the modem you had before.

LF2 is older than LFB. Are you sure voice calls still work?

I am on stock firmware , no roms/mods at all . Thanks in advance.
anyone ?
use faster fix to set your region pool
Sent from my GT-I9300 using xda premium
Do you have active data connection (mobile or wifi) when attempting a gps fix?
If not, it can take up to several minutes for a lock if you have not used Gps for a while since that is how it work.

It will change the ntp pool to one for your region, as the one that came as stock may well not be set for your region

If nothing of the above helps, do a factory reset in backup and restore or in the worst case reflash the stock rom with Odin.

Good idea. If that doesn't work then most likely it's hardware related. Mime locks on in seconds. GPS is light years ahead of S1 and S2.
But as mentioned earlier make sure you have a data connection or it could take ages.

Its the same but i just use the UK Pool server .
You could try the AGPS patch as a replacement editing your GPS.conf file to match .

Hi!
I think you should flash another modem, Modem/Radio/Baseband is all the same thing and can be seen by going to Settings - About Phone - Baseband. It's basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etc..
anyway, here is the collection of modems for our s2
also, remember that Usually just flashing and then using the same modem for 3-5 days should tell you how well it performs in your are and with you Mobile Network operator. Please remember that it takes around 2-3 days for a Modem to "settle" and achieve optimum performance, so don't judge how good a Modem is straight after flashing. That's where a lot of people fail when asserting battery drain.
on the sidenote, here is a youtube link on how to flash a modem:
