Tweak Your Kernel Settings with Handy and Free Application

The kernel is arguably the most important part of any ROM. A well written kernel makes the device rock stable, battery-friendly, and lag-free. That's why we have so many greatly written kernels are available here at XDA. But having a good kernel is one thing, and squeezing the maximum performance out of it is another. And without experience and excessive knowledge, it's sometimes difficult to modify even simple variables. More than a year ago we informed you about Trickster MOD,...

Sony Releases Open Source Files for the Xperia Z Ultra and M

"Good Guy Greg Sony". It's a rather affectionate title that Sony's been given for the past few months, particularly for their leading track record in GPL compliance as displayed on multiple occasions. So to make sure that they're continuing their fairly extraordinary performance, they've just released the open source files for the recently announced Xperia Z Ultra and M. Much in the spirit shown by Sony back with the Xperia Z, the company's gone ahead to make sure developers can...

Android Basics 101: Understanding Kernels – XDA Developer TV

Par for the course at XDA is to customize our devices. This includes a custom theme or a custom ROM with different launchers, layouts, and color schemes. However, an important part of a device's firmware and software package is the kernel. The kernel is like salt in a recipe for cookies. You don't notice when it's working fine. But when it's not, you notice. In today's video, XDA Developer TV Producer Kevin talks about the unsung hero of Android. He...

Dual Boot Your Samsung Galaxy Note 2

We don't usually cover individual custom kernels here on the Portal for the simple reason that thanks to the development community, there are so many great options available that we wouldn't have time to cover anything else. However, every once in a while, a kernel developer brings so much awesome to the table that it would be downright rude of us not to sit down and stuff our faces until we are fat and happy.

Custom Kernel for the HTC One Brings a Touch of Normality to its Button Layout

Despite being an almost sickeningly desirable, ultra-specced, and feature laden beast of a device---so desirable in fact that this self confessed Samsung fanboy considered making it his next device---the HTC One isn't without it's little quirks. These are quirks that may just be enough to sway somebody from choosing it over a competitor. One of these is the somewhat baffling decision by HTC to offer only two capacitive buttons and opt for an on screen software menu button in the absence of the...

XDA University: Adding Features to Your Freshly Compiled Kernel

We've previously covered step-by-step guides on how to compile your own kernel from source. Simply compiling some readily available source code though is only half the battle. For there to be any benefit of compiling and flashing your own kernel, you're going to need to make some modifications. Which particular changes you make is of course entirely up to you, and there are a huge number of improvements that can be made at kernel level to improve the performance of...

Linux 3.0.8 Kernel for 2011 Xperia Devices

Some devices just refuse to die, no matter how long they've been around. That said, a team of devoted developers has come together to bring the Linux kernel 3.0.8 to every 2011 Xperia device.  The last official kernel release from Sony (Ericsson) for 2011 Xperia Devices was version 2.6.32.

OK. It's no big secret. The HTC One is a great and exciting device. You've heard us talk about it---everything from the launch event and preliminary benchmarks to giving the device and its carrier variants a place on our forums. Now, we have kernel source for some One variants, which is great news for those looking to start development work for HTC's latest flagship. And since the device was only recently launched, with many carrier variants still pending release, HTC has done...

Linux 3.4 Kernel for the Galaxy S Plus GT-i9001

If your Android device has an unlocked bootloader, it's undeniable the usefulness of having a custom kernel on your device. With no release of Linux Kernel version 3.4 from Samsung as of yet, it's great to see developers on XDA all contributing to make this possible for a mid-range Samsung device, the Galaxy S Plus GT-i9001. The mastermind behind this creation is XDA Senior Member educk, who rebased support for the i9001 on the 3.4 kernel baseline, ahead of a release...

Sony Xperia Z Kernel Source Released Prior to Worldwide Device Launch

One of the most highly-anticipated devices debuted at CES 2013 is the Sony Xperia Z. With a 5" 1080p screen with a ~441 ppi, sitting atop a quad-core 1.5GHz Qualcomm S4 Pro with 2 gigs RAM and a 13.1 MP camera, there's no doubt that anticipation is warranted. With the device recently released in Japan, and a worldwide release date is speculated to be in the next few weeks, what is this? Kernel source already? This year, Sony Mobile has already...

An Official Alpha Release WITH Kernel Source? Who Does This Sort of Thing?

Here at XDA, we take the responsibility of carriers and OEMs to provide timely updates to their devices (and to honor their GPL requirements) seriously. There are those who do a good job (Samsung is one of them), those who don't always do a good job (HTC, Motorola, LG), and those who do a terrible job (Huawei, ZTE, Rockchip to name a few). But there is one who right now is doing a terrific job, and that is Sony Mobile. Back...

HTC Delivers ICS Kernel Source Code for the Sensation, Sensation XE and Vivid

HTC has always had a good relationship with its users, by industry standards.  They've made several game-changing decisions in the past year, including unlocking device bootloaders and confirming Ice Cream Sandwich support for a wide range of handsets, including some that were lower range than most competitors bothered to support. Now, continuing in an effort to improve that relationship,  HTC is challenging the idea that the company is slow to deliver source code for its devs and fans! HTC 's...

Fix 15% Battery Shutdowns on HTC Desire GB Sense Kernels

It is an issue many with older devices face: once the battery percentage hits the 15% or so, the device simply shuts down without any notice. What's the reason for this problem? Battery aging. The process of battery aging isn't inherently the cause, but as XDA Forum Member theGanymedes points out, it is the fact that your Desire thinks your battery is actually brand new. TheGanymedes puts it this way: ... your device thinks it has more capacity, when it's actually empty...

HP Releases Android Kernel For TouchPad

You may remember that during the HP TouchPad fire sale, a few slates slipped out with a primitive Android Froyo build on them. Well, HP doesn't seem to know how the tablets hit shelves with Android on board, but its decided to release the source code for the OS. Devs had previously called on the company to hand over the code, but the request was refused since HP had never intended for TouchPads to ship them with Android, so they...

Mod for EVO 3D Allows Device Wake Using Swipe Gesture

So what about phones without any physical front buttons? This is a problem that XDA Senior Member bponury is working to fix for...

Samsung Galaxy S I9000 Gains USB Host Functionality

Ever since the release of the Samsung Galaxy S in June of 2010, enabling USB Host has been a hot topic. While remaining a hopeful situation for a year and a half, success has remained just one or two steps out of reach.  Luckily, the tribulations of developer life simply cannot stop the developers of this site from overcoming OEM-imposed device limitations. Loosely based on a previously released set of USB host drivers that were later adapted to work with the...

I made a mistake.  A few days ago I reported that, with a slew of new kernel source codes posted on HTCdev, HTC is now GPL compliant.  That wasn't true.  I found out after saying it again on XDA TV.  On Twitter, @gu1dry said, @azrienoch Just finished the new XDA TV video, issue with the end, @HTC still hasn't released source code for the Evo Design... :/ That was true.  Somehow, I overlooked the HTC Kingdom (HTC EVO Design 4G and HTC Hero...
