WiFi consumes less power than mobile data

This is perfectly normal.

It's even one of the ten most common android tips - to keep WLAN ON even if you have data plan.

In most of the SoC(s) out there the 3G data mode can consume up to 4 times (don't believe but I've read it somewhere) the power of the Wi-Fi chip - as it looks for better signal/speeds constantly.

Even If you're using unlimited data plan it is advised to keep WiFi ON and use it (so mobile data goes standby) to save the battery. Quick google search will reveal dozens of results of this.

I'm sure some of you already know about this but I didn't realize that it was in the stock ROM till now. For those of you that don't know it let's you block certain numbers from ringing and I believe it even lets you do whole blocks of numbers like anything that starts with 1-877 or just anyone that isn't in your contact list.

It's in the phone app, Just hit the menu button and then Call settings -> call restriction. You can also long hold a number in the recent call list to add it to the restricted list.

Thanks people.
[Asus Transformer TF700] ShadowLea:
PDF: Perfect Viewer with PDF plugin (Both Free.)

Office: Kingsoft (free), DocumentsToGo or OfficeSuite Pro. (both paid)

Presentations: for images: Quickpic (just make a folder) (Free) or the office apps. ^
[Asus Transformer TF700] MarcoDev:

you should try for your office: Kingsoft and DocumentsToGo (it's awesome).

Great topic.

I hate Polaris office, and either it or Kingsoft changed the orientation of my Excel spreadsheets from "Left to Right" to "Right to Left" (Column A was at far right, B to its left, etc.)

I'll get a detailed list of what I personally use on my Infinity in the coming days.
[Asus Transformer TF700] _that:
:)

I tried once to create a very simple spreadsheet with Polaris Office. And with "simple" I mean about 10 rows by 6 columns with nothing more complex than additions.

After saving the xlsx file, Polaris Office could not even read its own file again! The extremely helpful error message: "An error occurred while opening the document". Yes, the very file that the very same app just saved a couple of seconds ago.

The funny thing is that Kingsoft Office, which I immediately installed after this incident, could read the file successfully. I still wouldn't do any serious business stuff on a tablet, but at least Kingsoft Office does the basics (like reading its own files) right. :)

[Samsung Galaxy Nexus] Tarzanman:
I am having a problem tethering my laptop and my desktop computer to my Galaxy Nexus ever since I installed the 4.2 update. My Nexus 7 tablet does not seem to have any issues connecting.

My laptop is a Lenovo Thinkpad T60-2007 which has an Atheros 42T0825 wifi chip. It used to connect to the Android 4.1 Galaxy Nexus hotspot without any problems under Win XP. Immediately following upgrading the Galaxy Nexus to Android 4.2 the laptop had problems. The laptop would connect to the tethering wifi hotspot, but would not be able to browse the internet (or in a few rare circumstances, would browse extremely slowly with frequent errors that would prevent web pages from loading).

I tried a factory reset on the Galaxy Nexus (which still left the phone at android 4.2), and there was no change in behavior.

I tried removing the wifi password and running the hotspot as an 'open network' and there was no change in behavior.

I tried a Windows XP reinstall on the laptop (to Windows XP SP3) and there was no change in behavior.

I replaced the wifi card (with and identical model) and there was no change in behavior

As a last resort (and because the laptop needed it), I installed Windows 7 Ultimate 64-bit on a new SSD and put in additional 2 GB of RAM.

Now although the laptop can still see the hotspot, it cannot connect to it. Even though the correct password is typed at the prompt, it gives a 'Network Security Key mismatch' error and will not connect. The laptop can connect to the hotspot if it is set as 'open', but will not connect to any sites or web pages (i.e. same problem as before with Win XP).

The laptop *does* work with the Galaxy Nexus via USB tethering, which suggests that there is some kind of wifi issue, but the laptop connects to my home wifi network (Linksys E3000 running stock firmware) just fine.

My desktop computer (running Windows 7) exhibits the same behavior as the laptop under Windows 7.

I was able to get a Macbook and a Dell Latitude laptop to connect to the wifi hotspot and successfully browse the internet (I will have to look up the model numbers later).

I am writing to try to find out whether anyone has noticed any similar problems/incompatibilities and whether anyone might know the causes.

Is there a problem with the b/g/n connectivity of my laptop? Did the wifi hotspot b/g/n configuration on Android change with the 4.2 update? Might a bad install of android 4.2 on my phone be to blame? Maybe there is a problem with g or n protocols? Which does the 4.2 hotspot use?

Thanks in advance
[Samsung Galaxy Nexus] deeprocks31:
same problem with me

i am also facing the same problem when i try to connect to any wi-fi network. it stucks on obtaining ip address. even though the password is correct. even i tried hotspot way to connect. via different s/w like connectify even i tried to make hotspot via cmd shell commands too. in that same it is not able to connect.

i dont know what the problem. i am currently using 4.2.1 rooted JB. i am planning for factory reset. but as you did earlier and no success so i might not do.

even with open wifi network it is not able to connect..!! it happen after the update..
[Samsung Galaxy Nexus] puothy:
The inability to either create a mobile hotspot and connect to it is why I went back to stock rooted 4.1.1. I have tried Muzzy and AOKP and could not create and connect to a hotspot using native tethering or Wifi Tether. It has been a while since I checked the forums, but did not see a solution that helped me

PS - I was trying to tether mobile devices not laptops though

As the title suggests How To Extract Stock Recovery.img From an android device ?
[Android Q&A, Help & Troubleshooting] dvucino:
well its quite easy but it can get complicate if you have bml partition

if you have MTD partition then conect via adb shell or in terminal emulator type: cat/proc/mtd and press enter

you will see which is recovery partition and then type: dd if=/dev/mtd/mtd1 of=/sdcard/recovery.img (note that mtd1 you must replace with number which is recovery partition)

after that you will have recovery.img on your sd card

but if your file partition is BML in that case you have a problem.

[Android Q&A, Help & Troubleshooting] StefanMiller:
OK, that is very interesting!

There´s another possibility to make a backup:

you need SP Flash tool: chinamobiles.org/attachment.php?attachmentid=23720&d=1354147322

and MTK droid tools: http://chinamobiles.org/downloads.php?do=file&id=733

Open MTK droid tools, connect booted phone in Android and click on "blocks map". Switch to full screen mode and make a shortcut copy of all the shown datas. Best: Print that page, you´ll need it later.

Close MTK droid tools again.

Open Flash_tool.exe.

Go to read back and remove all entries if there are any.

Click an "add".

Double-click on entry. Change name "ROM_0" to first entry of you printed list, i.e. "PRELOADER".

click "save"

in next window let "HEX" and enter start adress and length of the list in HEX format (starts always with 0x...)

i.e. PRELOADER start adress 0x0, length 0x40000.

repeat "add" with all entries like DSP_BL, MBR, EBR1, PMT... in my example 19 entries.

Take care that all adresses and lenghts are correct!

at least push "read back"

SP Flash tool will create a backup.

Hey guys, sorry to bother you. Wonder if you guys can help:

I was trying to back up the rom (UG007). I tried connecting to a laptop but it was not detected, not even as a unknown USB device. I connected the UG007 with a USB extender cable (I guess it is called the B type-the big one) with a Male-Male gender changer at one end to the large USB port of a laptop. Also used the mini/micro usb to connect power and HDMI to the TV. I had the "connect to pc" checked and USB debugging on.

Am I doing anything wrong?

Hi Pratikmore, thanks for your suggestion. I can only install the usb driver once the computer has detected the device.

Anyway, made it work. The trick is to connect your device with usb (both micro or the regular usb port work) and only then check the "connect to PC". After that the computer detects the new hardware and then install the usb driver.:D

Now I have to figure out how to backup the ROM in a relatively non-technical method. Any help?
