3G only

Hello,
I was wondering if there was anyway to strictly run off of 3G? I was using cm6.1 rc 2 for a bit but noticed it switches constantly between H and 3G.. and in return rapes my battery. While rooted with setcpu profiles I get 5-7 hours more battery life while running on only edge. Anyone have any ideas?

Switching from edge to 3G is a lot different from switching from 3G to HSPA+ which uses the same technology. Cyanogen just made the signal icon more accurate, because the stock rom doesnt differentiate between HSPA (3G) and HSPA+. ANybody with a standard 3G phone will tell you that running solely on 2G will save you a ton of battery. The difference from 3G to 3.5G (HSPA+), however, is negligable.
Either use 2G or use HSPA... i agree cyanogen should have an option to stop differentiating 3G fro 4G since it can be distracting.... and ignorance is bliss afterall.

so wait im running cynogen mod RC 2 will it give me a 3G icon instead of a H cuz i always get confused whether im on 3g or HSPA+(3.5g)

You can do this actually... search for the thread about editing the radio settings in system/build.prop

And there is really no battery damage from 3g to hspa switching. U could just enable 2g only in settings.

Help no 4g

I can't connect to 4g even thought I live in orlando. I only can connect to 3g. I'm using the newest royalmiui. I didn't have any 4g problems untill I flashed royalthunder then I only got 3g all the times. The speedtests I do show 3g speeds. Any help is much appreciated

Try a full wipe including formatting system and boot and reflash your Rom. Also make sure that your Rom supports 4G

I can't format boot in the new recovery. I have done a full wipe for every rom I flashed. All 4g roms. I'm gonna do it again when I get home to see what happens

Maybe the 4G tower is down? I'm not sure if roms have to be specially made to support HSPA+ because a) HSPA+ is the same technology as 3G so it should be backwards compatible; and b) the HSPA+ chip in the mytouch is only 14.4 mbps which is the fastest HSPA(3G) chip, not 21 which is HSPA+. I think.

check your coverage map on tmobile.com I have had the same issue and I almost started flaming rom cookers... even on cm7 I get 3g speeds. turns out the part of town I live in has low 4g coverages. Usually stock roms only have the H or H+ icon on the framework. so even when you're on 3g it shows H, even when you're on 4g it shows H. on custom roms notice you have 3 different icons. (or 4) H, 3g, EDGE, (GPRS)
H stands for 4g. mostly on custom roms this shows up when there is STRONG 4g signals
3g shows up all the time even though if a stock similar device such as another mytouch or a g2 shows H.
and edge/ gprs is self explanatory.
some roms may come with kernels that may have botched LIBS that prevent 4g connection (ie cooked roms from european phones like- desire HD etc...). get a friends phone that is similar IE a vibrant 4g, g2 or a mytouch and run speed tests using the OOKLA app on market. You will get the same results when his **** shows H and when your **** shows 3g.
Oh and they and you will be surprised at how much cell carriers lie to us about coverage
I live in North Houston and I can get full 4g speeds 2% of my usage times per month
I did this the other day with similar WHITE MYTOUCHES, one was bone STOCK no root, and one was root with cm 7- royal ginger 1.5

I live in Orlando Florida so my 4g coverage is beyond great lol. I had the galaxy s 4g and I never seen 3g on it. I kno this is a older device so 4g won't be as great as the sgs4g but it dosent mean I shouldn't pick it up at all

This is weird. I speed test on full 3g nd I get 9 dwn and 2 up. So its 4g just no Rom will say h

Call it dial-up, call it hand signals, call it morse code. If you are getting 9 down 2 up you are making 99% of t-mobile users jealous. Simple as that.

Lol... I have to drive 1.5 miles just to get cell service to make a regular cell call. Wifi calling is the only way I can use my phone.
Living in the woods at the base of a mountain kinda kills your cell reception.

I have the same exact problem but I have the speed of 4g just no H on my status bar
Sent from my HTC Glacier using XDA App

Yep my speeds are 4g on the my touch even though it never says HSPA just UMTS. But on speed test my vibrant is faster not sure why.

It seems like the 4g issue is with custom roms not the stock rom. I flashd stock with root and I never seen 3g only H the whole time

I have noticed that in east orlando by ucf I get a bad 4g signal more toward down town I get a much better speed.

Network 3G and H swapping problems...

Hi
I have this problem and i think ive come across a few people with the same frustration.
Which is the constant switching of our galaxy s fone networks frm 3g to H.... Happens so constantly it disrupts and keeps me in limbo so many tyms i cnt even tether properly with this problem!!!!
Please olease is there any fix for this out? Ive looked everywher!!!!! And if not. . . please as a humble request can a dev please create something so that only H frequencies are chosen and are prioritized so that it doesn switch to 3g please?????

Ha.
Yeah mine does too sometimes.
A way I get past it is to tap back button and select again and it quickly loads up in h.

Could be a problem with XXJVS radio? I go back to XXJVR to compare results.

HSDPA is an extension of 3g. It uses the same frequency. The reason it is switching is to save power for better battery life. It switches to H when you are using the connection, but than switches back to plain 3g when it is idle.

one will see 3g changing to H and call it a bug or so =)
i belive only on what is there in logs

Yes ofcourse its an extension from 3G to H .... But i am still using the dam network n it still keeps changing to 3g and H is there no way to keep it on one of em?

That's just how dataconnection works. .if you want to keep your connection in H-mode constantly, you need to make your phone to ping something for every 3 seconds...like ping -t 3 8.8.8.8 in windows (if I remembered it correctly).
In short: connection is in H-mode as long there is traffic. .

In my experience (from reading stuff here and observing my phone) it seemed that constant switching between H and 3G drains battery faster than if we could force the phone to use only H. From your post, I understand this is not the case. I never thought that 'switching' was a battery save feature...

I'm using CM7, and although it switches to 3G for a short period of time very infrequently, most of the time I have an 'H' displayed, even when it's idle. I also don't notice any significant battery drain. Maybe my phone is just crazy, though.

I've had this since day 1 with my phone, through many different roms... it's frustrating as all hell and really hurts my battery life and my patience

The switching from 3G to H is not the problem and not the cause of the problem here - it's just the symptom.
It's because data is lagging and stalling further upstream, so the phone is simply returning to idle as it should.
The solution is to change carriers to something that gives more reliable data.

Take a look at http://forum.xda-developers.com/showthread.php?t=837716 for a guide to disable HSDPA for better battery life.

Wouldn't the most likely cause of your phone switching back and forth be because you're losing connection? My phone stays in H when I need it, and leaves it when it doesn't. So...

Nope i have constant network on full bars... Keeps working only until the H starts swapping is the time my phone enters limbo and i lose connectivity

The problem is that it literally hangs between 3g and H changing constantly without loading anything. If I say for example on xda, touch a thread and it does this, it may stay in a changing to and fro for minutes and not load. But if I select thread again as soon as it starts doing it it opens to thread quickly and normal.

Problem with 4g

I have been flashing different roms for a long time. I never had a problem with my 4g connection. I'm now stuck on 3g. I have tried GB, ICS & JB ROMS. It doesn't matter which one I use u only get 3g. Sometimes I see the H for 4g but only for a few seconds or barely one minute. I have flashed different radios and some of them gave me 4g but only for a short time. I have formatted my sd card and did a full wipe before all the new roms. Nothing is helping me stay in 4g.
I'm not over on my data usage either.

It might just be your phone trying to save battery so its switching to 3g instead of using 4G or it might just be telling you that its 3G. Have you done a speedtest when the 4g flashes on and off

When I have 4g I get 6mbps down and 2 mbps up. On 3g I get 3 down and less than 1 up. How do I the phone to stop trying to save the battery? Even though I didn't have this problem before. I go all over town and it just doesn't stay on 4g.

Try a new ROM, or reflash the radio. but, if you're wanting to go back to 2.3.4 rooted, and want to get Gingerbread even better, check out myGinger ROM in the Dev section. I made it myself
