Q. I bought an Android Tablet 2.2
Kernel version: 2.6.32.6 jade@linux-server2 #207
Build number: V2.061
My tablet is not working correctly. The touch screen is not sensitive, you have to repeatedly pound the screen. And it WILL NOT charge. The red light stays on, and if you unplug it, it immediately goes black. Who do I contact or what do i do?

Can an android tablet be booted from a usb port?
Q. I was wondering if I can run one of those light weight linux distro installed on a usb flash drive on one of those android tablets.
1) Is there a cheap tablet PC (under $200) that can be booted from a usb port?
3) Can I find a lightweight linux distro that has all the drivers for that tablet?
Thanks for replying.

A. First of all, Android is Linux. It's a custom Linux kernel with a special software layer on top. And the customizations to the kernel and the software layer sitting on top of it are pretty important for it to run on the rather specialized smartphone architecture.
Second, a kernel has to be compiled to run on a certain architecture. So you'd have to find a version of Linux compiled for an ARM processor. That's not much of a problem. Several distributions, including Ubuntu, have ARM kernels. But then you'd have to have kernel modules for the drivers of the smartphone hardware, which... isn't nearly as likely. And you'd probably need a specially-designed interface, since Gnome or KDE really wouldn't work on a 4-inch touchscreen. And all of that would also have to be specially compiled for the kernel. And that's before we start with the application software. And by the time you got all of that working... you'd essentially have Android.
And even if you could do all of that, you'd have to have some way of booting from the USB, which you can't since smartphone firmware boots the kernel directly, without any sort of bootloader like you have on a personal computer.
If you want Android to be more Linux-y -- whatever that means, since the Linux experience differs greatly based on the graphical interface (assuming you use one) -- you can install a terminal emulator and even the bash shell. If you play around with it a bit, you might be able to install some command-line Linux software. But even then, it wouldn't be terribly useful, given the limited ability to enter text on a smartphone.

How can I optimize my battery life on a rooted android phone?
Q. i recently rooted my phone, and now i want to improve its battery life. what are all the possible ways i can do this?
i underclocked it but i want to know if i can do more. i also heard you can do it involving kernels, if so how and which kernel?

Does anyone know how to connect a flashdrive to a android phone?
Q. I have an android LG Optimus Slider (virgin mobile). and it would be vary useful if i could use my flashdrives with it so if anyone knows what apps/programs i would need or the hardware hook up. i have no problem with making some sort of adapter for the data port on the phone i just need to know how. or if anyone knows where i could buy some sort of adapter. and would i need to root my phone. all help appreciated
A. The easiest way to start is to grab a USB OTG adapter. If you can't (or don't want to get one), find a female USB A --> microUSB cable. On this cable, open the microUSB side of the adapter and solder pins 4 and 5 of the microUSB port together.
When you have your USB OTG adapter (or modified microUSB cable) you can then run the commands to load the necessary kernel drivers. Everything here is already on the rooted PlayBook, so you won't need any extra files. The commands are as follows:
slay RIM_usbmgr-Winchester
slay io-usb
slay devb-umass
sleep 2
RIM_usbmgr-Winchester -m0s
io-usb -domap4430-mg ioport=0x4a0ab000,irq=124
sleep 2
waitfor /dev/io-usb/io-usb 4
devb-umass cam pnp blk automount=+hd6t6:/accounts/1000/shared/usb:dos,automount=+hd6:/accounts/1000/shared/usb:dos
The only line you really need to pay attention to is the last one as it shows where the flash drive will be mounted after it's connected. You can specify different mount points for different partitions by separating them with comas (in the example here hd6t6 and hd6 are shown).
