[Q] Frequency - Galaxy S II Q&A, Help & Troubleshooting

Hi,
Had a search and couldn't find the answer I was looking for, so if it exists please point me the right direction.
Is there an app / widget that can tell me what frequency / band my phone is using?
To be exact, I want to know when my phone is on 850mhz or 2100mhz.
Closest I found was http://forum.xda-developers.com/showthread.php?t=913340 but it didn't work on my SG2.
Thanks in advance

i don't think there is one, but to make sure all available bands are open, open dialer enter *#*#4636#*#* then go to phone info, then the menu key then select automatic, this will allow all bands

you want too see what is the currect CPU freq?
well i just have set cpu widget on my first page it does good job
try it

Have you tried open signal maps?

May be not much of a help.

i found a band changer i would like to post it

i found a program that allows you to choose what band to lock onto, like 3G or GSM its handy for me because my 3G signal was low so it would switch to GSM when i didnt want it to, with this band switch i can just tell it to stay on 3G signal and it wont switch back to GSM. How do i share this find with the community? so i can post the cab file or email it to somebody so they can do it for me?
whats wrong with tapping on the antenna icon, then tapping on settings and then choosing the "BAND" tab to lock your bands !! it works fine for me !
blush did not know that (im a noob )
I've had mine for 6 months and never paid attention to that tab, so don't feel bad.
lol we all have to start somewhere !

[Q] Network Band Widget

I was wondering if there's an app that can add a widget to the homescreen that shows which network band (850mhz / 1900mhz) the phone is connected to. I browsed the Play Store and couldn't really find what I need. I'm aware that I can enter a code on my dialer to get the info, but I actually want to monitor which band its connected to without going through that. So a widget would be helpful. ANyone know of such an app?

wcdma only?

When I had my nexus one and nexus s I could create a shortcut with bettercut called phone info. It took me to a screen that allowed me to select GSM/wcdma or wcdma only along with a few more options. Where I work it switches from "4g" to edge constantly which I'm sure is draining the battery. I want to lock it to wcdma only but can't create the same shortcut. I'm not sure if it has a different name on gs3 or if the option just isn't there. Any help would be appreciated.

Found an app called network in the play store took me to the device info screen and I was able to select wcdma only.

[Q] No 3G, no EDGE, no data

Dear Sirs!
I have read the similar topics, but it does not apply, since people at least get 2G data.
My carrier uses 900 Mhz (only) for their 3G - is there any way at all to make that work on the Omate smartwatch?
Their Edge is also on 900 or 850 Mhz, and even that is not working (no E icon shows ever, with full signal).
When I tap the option Access Point Names I only get blank screen.
My watch is the new EU edition, I only got it now, but without data it is useless
I would really appreciate some help!
Kind regards.
One part solved...
Apparently the blank screen for APN was hiding the menu accessible only with swiping.
So now I do have the Edge connection.
I still wonder - is there any app or a way to enable 3G via 900mhz on this watch?
I am still non-rooted btw.

Question How to enable 5G band 40

(base on GSMARENA)
This phone support the following 5G bands:
5G bands 1, 3, 28, 41, 77, 78 SA/NSA
however, my current phone sim need to utilize the Band 40, n257/n258 for 5G,
anyone know how to enable or activate these bands? Is there any MTK engineering software for this purpose?

I'd like to help but I'm not sure if the solution I would use would fit your needs and capabilities.
The (apparently secretly hidden) Android Activity it calls is apparently
com.samsung.android.app.telephonyui.hiddennetworksetting.MainActivity​Based on what a free google free ad free gsf free shortcut inspector says
Activity Inspector
Having said that, I can bring up the HIDDEN Activity that allows you to select the bands available on the phone by calling the activity directly.
C:\> adb shell am start -n com.samsung.android.app.telephonyui.hiddennetworksetting.MainActivity​
They even make apps that do that for you such as this one.
Network Mode Universal​
See my screenshots below for my phone.
Hope this helps.

Thank you very much for your suggestion. I have tried all these and found:
Network mode universal - this is similar to *#*#4636#*#* for phone information.
Shortcut Widgets (+ Inspector), nothing shown in POCO X3Gt for band. it "maybe" work on your Samsung phone. Could not find any band information.
However, when get into *#*#3646633#*#* Developer option, it shows bands as attached photos, the Band 40 is greyed, no possible to enable it.

My response will be in two posts because I don't want to confuse you with the response about "Shortcut Widgets" so I'll take that separately as it's really useful only as a final step.
As for the band B40 being grayed, out, that is a problem.
My only experience with this band selection is on my phone, where nothing that is listed is grayed out. That is, for example, I don't have Band B28 on the phone (AFAIK) but that band is not listed either.
What I have that is listed, as far as I know, can each be checked.
So the fact you can't check a band that is listed, is really, I think, the problem all of the users here have to put our heads together to figure out why that is the case.
I don't know why you can't select Band B40 even though it's listed.
I can only suggest tests you can run to perhaps figure out why.
a. Anyone else with the same phone could run that test for you.
(Let's hope someone with that same phone will see this request.)
b. Maybe you can try one or two other "band selection" apps?
(This would eliminate it being a bug in that specific program.)
c. But the real problem may simply be the phone hardware doesn't support that band.
(I don't know any way around that.)

Ah. I think I figured out what I'm doing differently from you since *#*#4636#*#* doesn't work on my T-Mobile Samsung (we really need someone to test this using the same phone you have!).
My Samsung has its own app from that same outfit I referred you to
Network Mode Samsung​
I'm guessing that your "network mode universal" is (maybe) giving you a list of all possible bands but (maybe) not just the bands on your phone alone like my "network mode samsung" is apparently doing for me.
If you can find a network mode app for your specific phone, that may show just the bands you need... but... you already ran the *#*#4636#*#* dial-code to bring up the hidden activity I think... so you may already have seen that the dial-code you gave probably brought up only the bands which are available to you.
Hope this helps. I'm NOT an expert in this. I would hope others with the SAME phone as you have can confirm our suspicions or prove them wrong (better yet).

At this point you don't need Shortcut Widgets + Inspector, as it's only useful to find out what the hidden activity name is, and even then, you only need to know the name if you're going to create your own shortcut to bring it up.
It's useful mainly for HIDDEN activities, because once you know the name of a hidden activity, you can bring it up in a single click if you know what you're doing (you have to create a shortcut to it).
As far as I know, it's the ONLY APP in all of Android that does what it does (although others may exist) so it's a keeper, for sure; but it only tells you what you want to know AFTER you've already brought up the "activity".
An "activity", if you aren't aware of what that is, is kind of sort of like a "pseudo public page" inside any Android app, which can be brought up if you know the unique name of that activity.
There are something like three or four hundred public activities in the Android "Settings" app alone, while most apps have a few dozen or so public activities you can call up directly, which means there are about a thousand or so, which is why you might need an app that tells you what activities are brought up when you do stuff on the phone.
However, if you can ALREADY easily bring up the band-selection activity on your own, you won't need this app to tell you that so I'd ignore it for now. Sorry if I wasted your time.
Appreciate very much for your reply with detail explaination.
I believe this Dimensity 1100 is prebuilt with all bands when sold to each different phone company, however, MTK will price differently base on the the number of bands given (enabled), some companies may sell its phone with lesser bands so to lower its price to make it more competitive.
This problem is hardware problem, so it could only be done with MTK special engineering software or some special code to enable/disable them.
This is just my suspicion, I may be wrong....

I agree.
I hope you find someone with the same phone who can try it to help. Or someone who knows the MTK software. Good luck!
