4. What is Root ? Why should I root my SGW ?
Rooting the phone gives you all adminstrator rights, like you are used to on the PC.
Advantages:
All apps, also the sytem-apps like the ones from Samsung etc. are deletable (Titanium Backup required)
You can make your apps free from advertisements (AdAway,AdFree etc.)
All directories are viewable and editable (with ES Explorer or Root Explorer)
Swapping external SD and internal SD(with some tweaks)Disadvantages:
Officially: losing the warranty (but after unrooting or reflashing firmware, no evidence of rooting left)
4.1 How can I root my Samsung Galaxy W ?
Here is a detailed HowTo with different methods of rooting.
4.2 How can I undo the rooting of my Samsung Galaxy W ?
Therefore you will have to unroot your device this is also described in this HowTo. It is of importance to choose the right method to unroot your SGW.
5. What are Custom ROMs ?
Custom ROMs are curtumized firmware developed by different developers. They are very often better in peformance, because they can free up from bloatware(apps which are unnecessary for most of us) and are optimized.
6. What is overclocking ?
By overclocking the processor, you can increase the clock rate and gain more performance (of course it has to run stable). The default clock rate is set at 1401MHz(1,4GHz) for the Samsung Galaxy W. Increasing the clock rate usually provokes a growth of temperature.
7. What is flashing for ?
If you have gained root access, you will be able to delete important apps which may be necessary for android to work. Deleting these apps could end up with a boot loop(the phone stucks at the bootscreen) or other problems. In this case flashing is the only possibility to get the phone running again.
