I have a very weak reception, ranging from from -90db down to -105db, inside my condo with my Bell i9000m leading to calls drop.
Dialing *#0011# on the dial pad and walking around the place, I noticed the phone kept switching between the 1900 and 850 bands back and forth.
I kinda suspect the calls drop happen when the phone switches from one band to the other, so I'm wonderring: is there's a way I could set the phone so that it only uses the 850 band when I'm home?
Since the 850 is better at penetrating walls, wouldn't that help a little?
On older phones, non-smart ones, there usually was such a parameter to do that.

I had exactly the same problem plus my phone would turn off as well when it lost its signal for prolonged periods of time. I found a post on this forum which gave a keypad code to type in.My phone has worked perfectly since then. Unfortunately I can't find the post to link it to you. I'm sure if you search for a while you could find it.
Hope this helps a little.
In the dialer: *#*#197328640#*#*
1. Debug 2. Phone control 3. Network control 4. Band selection. (not the menu#'s)
I tried WCDMA all and was getting the shut off when phone loses signal when asleep. Just set it back to auto but might try setting it to 850 and see what happens. This doesn't happen too often, I get full bars at home and 2-3 bars at work but do lose signal sometimes.
Hope this helps and let us know how it works for you.

Forced my cell to use the WCDMA 1900MHz band instead and tadam... no more calls drop.
By the way, there a shortcut to get to the band selection dialog: *#*#2263# or *#*#BAND# if you prefer.

Hi there,
Can anyone please assist?
Whenever I select a phone Band of WCDMA and am operating on HSDPA [H], my Touch Diamond which is on Hutchison 3's Network, has very poor reception whenever indoors and has lots of call dropouts. The phone shows just the dot below the Antenna Icon or just one bar to the right, most of the time while on HSDPA.
Whenever I select a phone Band of GSM, and the phone switches to an Edge connection [E] then I have nearly full signal strength, but this is considered "Roaming" off my network service provider and therefore is much more expensive to use. (What a scam!).
I have tried installing several radio ROM's but it has not made any difference to the signal strength and dropout problems. The Radio ROMs tried so far:
1.09.25.23 Official (Quad Band)(52.51.25.26H)
1.08.25.20 Official (Quad Band)(52.44.25.24H)
1.08.25.08 Official (Quad Band)(52.44.25.24U)
1.00.25.BS14 Official (Quad Band)
1.00.25.06
The phone has had this problem with HSDPA signals since I purchased it.
My questions are:
1. Have other people experienced this kind of issue and is poor reception indoors normal when on HSDPA [H]?
2. Is there a way to force a Touch Diamond, say through a registry hack, to use a Band of WCDMA but stay on [3G] instead of using [H] ?
3. Is it more likely that my phone is a good candidate for a warranty return as perhaps the antenna is dodgy?
4. Are there any other suggestions I can try to fix this problem?
Any guidance here is appreciated.
Thanks,

I love my Diamond and think that it is one of the best PDAs I have used. Its small size is just perfect for me, and I find other phones eg iPhone, Touch HD too big for me as a phone. I have customised it to the extent that I get no lag issues and it runs really fast.
The one flaw which I haven't been able to fix is its poor 3G/HSDPA reception compared to other phones like my previous Nokia. (The iPhone suffers from this problem also).
You obviously live or work in a poor 3G reception area for Three. When your phone switches from 3G to GSM, it will invariably drop the call if you are on a call. If the 3G reception is strong, indoors or outdoors, there will be no problems. 3G reception can fluctuate especially indoors. I dont think there is any fault with your phone.
Your options are to:
1) Change mobile phone provider
2) Force the phone to use GSM in low 3G signal areas and you will have no problems with call drop outs. There is no extra cost for roaming in GSM with Three for calls, only for data.
I use option 2, since I use WI-FI in the house for all my data needs. The easiest way to do this is to use Comm Manager, under Settings, Phone, Band, and then select GSM in 'Network Type' to force it to use GSM, or WCDMA to force it to use 3G/HSDPA. The other option is Auto, which is the cause of the problem. I use a hack which enables a '3G' toggle in Comm Manager so that I can change from 3G to GSM with the simple touch of a button.
You will also find that the battery life of the Diamond is really poor when it has to constantly change from 3G to GSM and vice versa. On the other hand, forcing it to use GSM and only switching on 3G when you use data, will actually prolong the battery life. I get up to 2+ days battery life when using GSM only.

Riker88, appreciate your comments and feedback. Thanks.
I tried my 3 SIM in another Touch Diamond and found the problem with poor HSDPA reception on Hutchison 3 was exactly the same on the other phone. This likely means it's the provider, or phone + provider combination. In either case, darn it !!
I generally operate with the phone band selection on WCDMA, rather than GSM or Auto. I noticed yesterday while driving around the city that my phone switched from the HSDPA (ie. 3.5G) service with the [H] icon on the screen to the 3G (ie. 3.0G) service with the [3G] icon on the screen, and the [3G] service signal was stronger. What I'm wondering is this:
Is there a way to force the Touch Diamond to use [3G] all the time, instead of [H]?

From my understanding, you should get same radio signal strength no matter it is 3G or HSDPA enabled. Your observation may be your original signal (with HSDPA) is too weak and hand-over to another radio station that have stronger signal but no hsdpa.
I also notice that the 3G reception capability of diamond is weak. But this is nothing dealing with hsdpa.

From what i've seen - that's true. (i have the same problem).
Is there any way to get my Captivate to stick to 850 band only, and not switch to 1900. I live in an area where I have 3G coverage on both bands.
Edit: I can get to this using SGS tools, but that would be only till a restart. Any way to get this to stick permanently until disabled.
Go to the phone dialer and put in *#2263# from there you can select what band you want. To check if it took, type *#0011#
Yes.. what he posted above should work even after reboot
The moment I set to 850 its switching from 3g to edge. Strange. Cos when on 3g mode its always been on 850, atleast 80% of times

Thats one thing the bugged me is that this phone ... AT&T version anyways.... loves to camp on 1900mhz more and would be fine if it would switch to 850 when needed..... alot of time I would be at -111db and still on 1900 when 850 in the same are would be at -103db.
I enable 850 that way but once you reboot... you need to do it again.....

Technically, the lower band should have lower signal strength reducing radiation. Plus should be using less battery power. That is why I am seeing how to get to 850.
Anyways, I think I'll leave it how it is.
Hi,
I was wondering if we can turn off hsdpa to save battery life, i used to have a Captivate and we used this secret menú to disable hsdpa, leaving only the 3G which consume less battery than Hdspa and is faster than 2G, but i can not find this menú on my nexus 4, someone knows how to do it?

[REF] WORKING: How to disable HSPA / HSDPA for better battery life
Hi people.
One way to get longer battery life is to disable HSPA and just use 3G. 3G (UMTS) is not as slow as EDGE/GPRS but doesn't use as much power as HSPA.
Here's a quick comparison of *typical* download speeds:
GPRS: 48 kbit/s, EDGE: 150-200 kbit/s, 3G: 384 kbit/s, HSDPA: 1000 kbit/s
After some searching, I've found a method that actually works for our Galaxy S:
Go to the phone dialer pad and enter this code: *#301279#
Click [2] CHANGE HSPA REVISION
Click [1] RELEASE 99 (HSPA OFF)
Then you should see something like:
CHANGE_R99
HSDPA OFF, HSUPA OFF
Done!
Press the BACK button to exit, or press MENU button then END.
The setting should take effect shortly after you exit the menu. To be sure that the setting take effect, toggle Flight/Airplane mode.
You could store that number in your phone book or speed dial for a quick way to toggle HSPA.
The setting STAYS ACROSS REBOOTS!
If you want to enable HSPA again just go back to the same menu and choose [3] RELEASE 6 (HSDPA/HSUPA).
Just tested it with the XXJPP radio and it really works.
Longer battery life at last!
Quick way is Settings-More-Mobile Networks- Use Only 2g.
Better way is to install a toggle control app that let's you do it in one touch.

Thx, But 2G Its too slow, with this method the Hsdpa is off but the 3G still working so Its faster, but Looks like lg doesnt have this option or i can not find it.... Jet
HSPA is 3g
Sent from my Nexus 4 using xda app-developers app
Try this code:
*#*#4636#*#* :good:
Yeah the main way is to check "use 2g only" which would give you edge only and may save battery but yes it is very slow.
There is also a toggle 2g app which makes it more convenient, or you can use tasker.
Based on what I've read on the forums I'm pretty sure HSPA is 3g. In which case theres no in between.. if you go through the dialer menu you can choose wcdma/gsm which is 3g/2g. We're used to thinking hspa is 4g but its actually 3g since true 4g is actually LTE. Confusing, I know.
Please correct me if I'm wrong.
HSPA/HSDPA is enhanced 3G. Sometimes referred to as 3G+. It is faster than 3G, but not near as fast as LTE, which is true 4G. I speak mainly for the AT&T network because I spent a lot a time with this on my HTC Inspire. AT&T invested a bit of money enhancing their backhaul to accommodate HSPA. I lived in a marginal area where my Inspire was typically on 3G but, by design of the device, was constantly searching and switching to HSPA and back and forth. This constantly drained my battery and caused dropped calls because it was switching towers when doing this. I ended up having to place a microcell in my home to alleviate this, since there was no way to do it thru the device. I'm not sure how my N4 would act today because I still use that microcell.
The OP was asking how to turn off HSPA. In the context of this phone, that's 3G. The next step down is Edge.

HSDPA has no more battery drain than 3G...
3G is not HSDPA, is UMTS. HSDPA is 3G+.

True that. Considering this is considered a developers phone that is unlocked and unbranded, I'm a bit surprised at the limited band selection.
It's a 5 band GSM phone, what more would you want? Other than LTE, obviously, we've done THAT discussion to death
Sent from my Nexus 4 using xda app-developers app
I was referring to the ability to select the bands. When I go into the hidden test menu and try to select a radio band, I get a message that states "Unfortunately, the process com.android.phone has stopped". And yes I know this was done intentionally to hide the LTE band. My point was that I consider that somewhat odd. That is all. With previous phones I found the ability to switch bands useful for signal tests in my area, even though I couldn't always make them stick.
THANK YOU. I can finally enjoy fast (Fast enough for my needs) internet without the blackhole drain of HSPA+. 3g, UMTS, does not drain as much as HSPA+.

It's probably an NV Item in the Qualcomm radio. You would just need to find what value it needs, put the N4 into "modem" mode, and use NV Item editor or similar to change the value.
turn the data and gps off ,.turn down screen brightness, then you will found very long battery life for you
Just found a small trick to use only 3G instead of 3G preferrd.
Just dial *#*#4636#*#* select the desired radio in the drop down menu. WCDMA is 3G only.

Yeap yeap. Known for some time already. You can also force it to connect to 4G network instead of 3G network by selecting "LTE Only" but you won't be able to receive/ make calls and sms. Good for situation where you wanna use Internet and it is loading really slow cos your phone finds that the 4G signal is too low and determines that 3G is would be faster for you. But low signal 4G compared to higher signal 3G, 4G still wins most of the time to me.
Just a question. I had the S8+ S9+ and the Note 9 and seems like all the Samsung phones have terrible capabilities of keeping a signal in bad areas. We own property use mainly for long range shooting in FL and it's hit or miss getting a signal. Wonder if the S10 is any better? I don't think so but wanted to ask.
We switch to the Moto's Hers Z3 MIne Z4... and Motorola is the best same area up at property no issues at all. So proof that sammy radios suck.
FYI we are on Verizon.
:cyclops:
I have 3 towers, all 2 miles each away from my house, and I sit on 1 bar, if I'm lucky....it sucks.also on Verizon. Have an s10.
Just want to share how I solved this or similar problem in Malaysia. I find S10 sucks at band switching, I can literally see my 4G bars jumping from 1 bar to 4 bars then 1 bar and so ford , you get what i mean. This phenomenon is more significant when the phone is hold landscape or some of us called it "the death grip". Basically what the bars jumping means is the S10 is trying to switch to a "what it thinks more reliable band".
well, here come the good after all the bads, you can fix the problem by fixing the band, preventing it from keep switching like crazy. Luckily for me, my carrier provider use band 3,7,8 for 4G. i believe band 3 is 1800 MHz, 7 is 2500 MHz, 8 is 900 MHz. if you know physics, lower frequency can penetrate walls better, so I fixed my s10 to band 8. Oh ya, 900 MHz may benefits gaming latency as well, although lower down link.
Now my S10 have constant 4 bars in my living area. But beware, not all places have the same strength for all band, you need to find out your self for your carrier. This is how you can do this trick:
Go to Phone App -> Dial *#2263# -> Stack 1/2 (number of SIM) -> Band Selection -> LTE -> Band of your choice.
One nice thing about S10 is you can fix 4G band without disabling 2G/3G, which is super nice when you go to non-4G area. You can always revert to default by selecting Band Selection -> Automatic -> Preferred bands
Hope this helps.
