how to change the cell phone frequencies of a phone. I'm looking into a knock off 4G phone, but the frequencies run on 850mhz. I'm looking to switch it to Verizon's 700mhz 4G LTE network. What are the kernels or ROMs needed in order to do this? The phone has the hardware to support GSM and LTE. I may even test it out on my Droid Razr, as I've heard they have both but Verizon disabled the GSM function on it.

Whenever I try to set minimum CPU frequencies higher than the default value, no matter what app I'm using or what kernel or Rom it just won't stick. Governors and maximum frequencies stick though.

View 3 Replies View RelatedIm using bugless beast with P3droids 1250mhz lv kernel. I was want to do custom frequencies to add more steps. specifically i want 125/250/400/550/700/800/850/900/950/1000/1050/1100/1200/1250 1. is that safe? im not going any higher or lower than I already was
2. what numbers would i put in the setcpu file. is 125mhz 125000(1000khz/mhz) or 12800(1024khz/mhz)? im, assuming the latter, but unsure.
I want to create an application that is similar to a phone call, where it produces sounds through the speaker and receives sounds through the mic. i want to know if i can have an access to control the speaker and the mic to produce and receive sounds simultaneously (like a regular phone call) in my application. i also want to know if it is possible to specify the range of frequencies of the produced and received sounds.

Battery used by cell radio?
Does this just mean I am in a bad cell zone? This is my reading at home and it is the top battery usage on the chart, followed by wifi at 24% (on because I am home), and phone idle at 23%.

View 1 Replies View RelatedDoes anyone know of an app that can test what frequencies are being used in the area? I'm trying to figure out if something is interfering with my wireless router, and if so what it is. I've got "WiFi analyzer", but that doesn't show anything other than wireless signals directly from routers, even though a cordless phone runs on the same basic frequency.
In other words, I'd like to find an app that shows what frequencies are present near my phone, including what my phone is putting out. Is that possible?
I took some videos on SGII. They show up sideways on pc in mp4 format. It looks like I can change the orientation in Windows Movie maker, but when I try to save it as mp4 - it says "invalid format". It has it's own format to save it in and doesn't appear to have any other options.

So here's my question. Is there a ROM out there, or a guide to making a custom one, for removing the cell and 3G functionality? I haven't even found anything for a bootloader or recovery for it, so I don't have high expectations.
I was never really big into photography as its kind of expensive, but the camera on my own s3 is pretty awsome. I was wondering if there is a guide anywhere on taking different kinds of pics etc or what the different modes are for with situations. Like I don't know what macro is etc. Just looking forward to taking some cool pictures on my phone and maybe sharing on instagram. I wouldn't mind doing more than auto pics.

I am thinking about skipping this round of iPhone and opting for an Android handset for use on AT&T.
I may wait for the Samsung Captivate, but am wary about how it will stack up, particularly when it comes to the feel of the touchscreen compared other handsets. (The sensitivity of the touchscreen on my 3GS is one of the biggest factors that has kept me from switching so far.)
My Question:
Aside from the Nexus One and Milestone (international version), what other high-end Android handsets can be used in one way or another on AT&T's 3G frequencies?
Would the Incredible, Evo, or Droid X support 850MHz and 1900MHz if they are SIM unlocked?
As I am still catching up when it comes to Android, due to lack of a selection of devices to play around with at AT&T.

I received text messages from my husband's phone # but he swears he didn't send them, they said: busy right now, talk to you later. Is there something in the settings that he activated without knowing what it was, because one of his co-workers got the same text right.

I'm about to retire my trusty old Epic 4G and whats the best way to store my battery on it. I will be removing it but I'm not sure whether I should store it fully charged or half way charged. If I remember correctly, I read somewhere that you should store your battery with 50% charge for it to have some life if you ever need to use the phone months or a few years time. Storing it fully charged can pose a threat due to the battery blowing up?!?! Not sure if this is correct or not. What to do to preserve your unused batteries in your old phones?
View 6 Replies View RelatedI would like to have the cell network type displayed while I am connected to WiFi in the status bar signal cluster. Currently, once you connect to WiFi, the LTE, H, E, etc, go away; I'd like them to stay.
I can move the WiFi icon over to make room for the type icon (LTE, H, E, etc) just by deleting "android:layout_marginRight="-6.0dip"" at the end of the "id/wifi_combo" line in res/layout/signal_cluster_view.xml in SystemUI.apk.
Where is the function that turns off that cell type icon when WiFi is connected in SystemUI.apk? I know the system can detect the type of network whilst WiFi is connected, it's just a matter for forcing that icon to stay displayed.

I was wondering if an android cell phone 3G bandwidth is related to a hardware or software issue?
IE: My Motorola Defy+ has 2100 bandwidth, I know it cant work on 3G for 1900 bandwidth, buy i want to know if i can solve this changing phone rom or is a hardware problem...
Any other way than going to recovery and wiping data/factory reset in order to unlock the cell becausei have much important data in my phone in internal sd.
View 1 Replies View RelatedI recently purchased this Tablet cum Phone Device (Asus Fonepad) in India. I found this device very impressive with decent battery backup along with great standby time. Everything was allright. In morning I found heavy battery draining during standby.
Next day I uninstalled that Black market application and Uninstalled Exdialer with all downloaded themes. I got full signals and everything was working fine. But the Battery Drain in standby remain same. I observed the situation till next two days. I searched to forums and did following things:
1. I made factory reset to my fonepad. which was haviing 4.1.2 Android after updating through OTA. Which remains same after Reset.
2. I didnt install any other applation
3. I turned of all battery comsuming services like GPS/ Location reporting/ Data/ Wifi/ Uninstalled Google Play Service Updates etc
4. Installed Wakelock detector, Better Battery Stats etc All are showing that phone goes in deep sleep no prblem but Wakelock detector show that Cell Radio wakes up so much time when phone is on sleep mode. Default Battery monitor of Android Showing "Mobile Data" as most battery comsumer.
One thing I want to mention here the device is supportive to mini sim only. I was not having mini sim so I went to market and mobile shop keeper cutted my Sim to adjust into that slot and it woked. I was using same sim from Day first. It's Vodafone INDIA.
I have not rooted nor flashed anything from my fonepad. I am reached to the conclusion that There is some problem with Exdialer installation and applying new/old theme combination to it which made me device with no signal. And now The Cell Radio has been changed which is attempting to achive something in standby mode. Which is causing heavy battery Drain. Standby time is reduced to almost 15-16 Hrous
I've ported a Hero ROM to a HTC Magic.Here's my problem:
Problem: There's a great battery drain when you're connected to the network (no data but just mobile network for calls/SMS)
Ported ROM: Sandwich Deluxe 4.0 .
Original ROM: Hero ROM
Kernel: carz-2.6.34.4 (fast and stable)
The mobile network drains battery.I'm not in a low signal-area. Everybody who uses the ROM has a drain.I'm using a 2.x.x instead of a 3.0 kernel for an ICS ROM, can it be that this mismatch creates the drain?The phone displays a singal strength of 0dBm 97 asu. (Not normal?)
What doesn't cause the problem? In airplane mode there is no drain at all. So it is unlikely that some apps causes the drain.Wifi, GPS, sync, ... are all disabled.
What do you expect from xdamembers?
- Confirmation if the kernel is the issue of the drain. If not, I would like to know which files (in ROM) are responsible for network signal.
Is this possible? , I own a business and want to use one of my dummy lines for the business #, instead of my personal line so I don't have to carry two phone's like a pimp, and if it is possible can that line be turned off after biz hrs?, my business is mobile.
View 9 Replies View RelatedI have a certain group of mp3 files on my device for which I wish to change the album art image. I used a program called "mp3tag" to edit and save each file (from my computer) with the new cover image embeded in the tag info.
However, when I play these tracks the original album art still displays on both my music players (stock player and Just Playlists). If I go back and mount the device as an external drive and view these files again with mp3tag, it still shows the corrected/updated image.
why the correct imbeded cover art will not display when I play the files on my phone?
