FAQ: Can I replace the home/touch keys or silver frame/bezel around the screen?
A:Yes but its a bit tricky trying to remove a good working screen from the frame. Search for 'separating screen from front frame on s4' to see how it can be done.
Q: How do I replace the power switch?
A: The power switch can only be replaced using a 'hot air' soldering iron. Google 1053010945 for the switch and find a local tv repair shop as they should have the tools and skills to replace it
Q: Can I just replace the glass screen as its only $20?
A: Replacing the 'glass screen only' can a bit tricky. There are plenty of videos showing how, but the results are varied. Unless you use 'optical adhesive' and a possibly a vacuum chamber to remove any air bubbles its not going to be a 100% repair. If you are happy to have an 'air gap' between the screens (which gives an 'oil slick' affect when you press down) then a glass only repair is fine. Most people replace the complete screen assembly with the frame or you might find a 'glass only' replacement service on eBay.
Q: Can I replace the USB charging port?
A: Replacing the usb charging port needs the use of a 'hot air' soldering iron. Google for 3722-003512 and find a local tv repair shop as they should have the skills and equipment to replace it. Or you can invest in a wireless charging kit (search eBay for 'galaxy s3 wireless charging') and use wifi to move your files..
It's worth paying the little extra for a new screen that comes with the frame(front housing/bezel) as you will not need to separate the broken screen from the frame and will have a nice new bezel.
Same procedure for i9300 T999 i747 i535 L710
If you've seen the drop test then you might find this puts your mind at ease for replacing the screen..
