Samsung Galaxy s2 switcing question ?

mjdj1689 · 14-09-2011, 02:41

My Galaxy is s2 is sim free, and I tried a 3 sim in the phone just now , where I live there is only 1 3 base station, my question is why does the phone keep switching between 3g and the H symbol, (3.5G) if there is only one mast near me, and 3 have also confirmed i only have the 1 mast, so its not switching to another mast . ?

Thanx

I had exactly the same problem i think is may be a 3 and a galaxys 2 thing for what i can tell the phone switches back to 3g if there is no active date throughput or to save battery what you need to do is goto the keypad #*9900# goto fast dormancy and disable it then reboot the handset.This should help to a certain extent but not 100%,reading xda developers this will enable the H for longer and its supposed to save your battery again, Just to add you can always revert back by using #*9900#.

I think it's dependent on the strength of the signal you are receiving. It happens on mine when I'm indoors.

Yes and no with the galaxy s 2 it will still happen even if you have a full signal if your using something like tvcatchup or in my case slingplayer mobile or any other streaming for example using #*9900# will enable hspda for longer if you have any usable signal strengh

That code doesn't work on my S2.....I don't really find the switching a problem and don't notice any majorl change in downloading times. So I think I'll just be happy with it as it is....
@jcm193, I'm on the O2 network by the way so it's not 3 specific

Are there and downsides to using this code?

Can it cause any problems?

I have a S2 and want to be sure it is 100% safe to enter this code.

That code does not work for me either, i type it in to the phones keypad, the press the call button, and get invalid code.

In a full strength signal area, it still reverts back to 3g, but in some areas now getting Hspa + (on the 3 network) im getting 9 down and 1.4 up, thats fast, and impressive, well my other phone on Orange is only 1. 3 down.

GrannyGruntbuck · 15-09-2011, 21:28

I have used the code and did not get any error messages.

No idea if it has made any difference.
