Tap2Unlock Brings Security to Tap2Wake

android-icon

Android OS offers many ways of unlocking your device. Among the most popular are entering a pattern or PIN and face unlock. Although patterns and PINs can be pretty secure, there are still ways to improve upon them.

The Android kernel offers many functions that can be used even when the screen is powered off. Double-tap-to-wake is a common feature that can be found on many custom ROMs here at XDA. XDA Senior Member goutamniwas created quite an interesting method for screen unlocking using the tap2wake technology.

With Tap2Unlock, you can unlock your screen by entering a PIN code while your screen is off. This module splits the screen into four squares. Pressing the wrong pattern will light up the screen but disab. . . READ ON »

HTC Releases Kernel Source for One M7, M8 GPe Devices

htc-one-m8-vs-one-m7-22

A few days, we talked about the Google Play editions of the HTC One M7 and M8 getting an Android 5.0 Lollipop update. Those updates, in addition to the totally new user experience, gave developers a chance to use the updated binary files, which were built to handle Android 5.0 without issue. HTC did its homework accordingly, and has now released the kernel source in a timely fashion.

Most big OEMs respect open-source licensing and release the GPL-compliant kernel source code for all their shipping devices and firmware. However, this usually takes a few weeks to make its way to developers, but HTC has released these files almost instantly, thus giving developers a chance to implement the changes into the kernel b. . .

Easily Load Your Favorite Kernels with Kernel Manager

image

Custom kernels are designed to make our devices run better, faster, and be more battery friendly than their stock counterparts. Kernel development is definitely not easy, as it requires lots of knowledge about the Linux ecosystem and coding ability. You can find multiple kernels available in basically any device subforum.

Kernel developers often create applications to keep their users on updated versions and to streamline the update process. Users can easily download the kernel and install it without even touching a USB cable, which is surely a convenient way of updating. However, not every developer creates such Android applications, so it might be a bit problematic to keep them up-to-date. XDA Re. . . READ ON »

HTC Desire 816 Gets Developer Treatment with Custom ROM, Recovery, and Kernel

HTC-Desire-816-vs-Asus-ZenFone-6

In the last few days, we’ve talked about some fairly high end devices receiving official ports of popular ROMs or updates via OTA. Users of mid-range devices usually must be more patient when it comes to waiting for their devices getting developer support. Patience, however, is certainly a virtue.

The HTC Desire 816 was announced at MWC in Barcelona in February of this year and eventually released in April. This 5.5” phablet brought a number of high-end specs into mid-range world. Now, Desire 816 owners have a proper reason for celebration, as XDA Recognized Developer Grarak and XDA Senior Member v_superuser laid the cornerstone for the future development for this device by releasing . . .

Charge Your Kindle Fire HD 7″ Faster… Much Faster

Qualcomm-quick-charge

The Kindle Fire HD 7” is quite an intriguing device. Technically it uses its own operating system, “FireOS,” which is essentially a skinned variant of Android 4.2.2. Of course, it was only a matter of time before fully fledged Android was ported to this device. Actually, lots of development related activity has happened since September 2012, when the device was made public.

One of the latest development projects for this tablet comes from XDA Senior Member SafinWasi, who compiled a new kernel for this device with fast charge enabled. Fast charge itself isn’t a new concept, and you can find it in various projects since 2011. This modification enables charging with the . . . READ ON »

Convert PNGs into RLEs Easily on Any OS with PNG2RLE

png2rle converter

Unlike other operating systems, Android uses its own graphical image formats. Most of the images use in the OS are PNGs, but there are some devices that use the RLE image format for their kernel logos. This format provides a pretty good compression ratio and is very fast. Sadly, converting a PNG file to RLE isn’t easy and requires some tools. There are plenty of them, but not many can be described as cross-platform and don’t require ImageMagick to work properly.

If you are looking for a simple tool able to convert PNG files into RLE files in just few seconds, XDA Senior Member alireza7991 has created something for you. PNG2RLE is a text tool that converts raw PNG images into the kernel logo co. . . READ ON »

Google Pushes Experimental Linux Kernel 3.10 Defconfigs for MSM, Exynos and Tegra SoCs

Linux Kernel

The big hype surrounding Android L’s unveiling caused us all to skip one important change, the debut of the Linux 3.10 kernel in the ARM world. New smartwatches like the LG G Watch and Samsung Gear Live work atop the Linux 3.10 kernel. However, most currently released devices are using the Linux 3.4 kernel, the ninth long-term stable release from 2012, with supports that expires in October 2014. Google is eventually planning to switch to 3.10 from June 2013, the tenth long-term stable release. In the Android Wear source recently pushed to the Google Git, you may find some pretty interesting findings.

If you take a closer look at defconfigs, you might notice that there are some experimenta. . . READ ON »
