A friend asked me to repair her friends Samsung Galaxy S3 mobile phone, that had a broken glass screen/digitizer, so I had a closer look at it. The process of replacing the glass screen/digitizer on a Samsung Galaxy S3 is straight forward and not many tools are needed. However, what you really need is patience… a lot of it.
This post shows how it is done and why I still would not recommend it anyway.
There is a lot of confusion and wrong information in the internet about the Unified Extensible Firmware Interface (UEFI) and how to set it up correctly – especially under GNU/Linux. What makes things worse and also confused me a lot is that all vendors tend to implement this “standard” differently. So although UEFI is defined as a new industry standard replacing the BIOS, it can hardly be called “standard” at this time. Yet another problem of understanding UEFI is, that people seem to mix up words that have a special meaning.
My old notebook still uses the old BIOS-MBR setup, not capable of any UEFI fancy-ness. But it is dying, so I recently bought a new one. It is an “HP EliteBook 840 G1”. I used that opportunity to familiarize myself with UEFI and GNU/Linux.
This article explains two things (only taking GPT setups into account):
How is UEFI implemented in practice and set up with GNU/Linux?
The Archos 101 has a crappy touch screen, as all the owners of this device already know. Most of the other problems could be fixed using a custom rom like urukdroid. But the touchscreen has been bugging me for the past year now: the touchscreen sometimes just acts weird (wild and random clicks, or almost no reaction), until it is “recalibrated”. No wonder, since it is a cheap USB touch screen “UNITEC USB Touch (Win7)”, probably made for windows 7 netbooks. Since the recalibration is hidden deep in the android settings, but needs regular access, I wrote a simple app as a “shortcut” to it. You can find the app download link at the end of the article.
