Hi. Just a quick word to avoid confusion on these units. There is more than one model, and they are quite different in their design, both in the screen design and how it’s fitted together.
The model I have with me (I’m fixing the cracked touch panel) is held together by the same 4 screws as shown here, but the screen looks far more modern. The one shown in this guide appears to be the old style of touch panel, these have a kind of hazy appearance to them. The model I have, which is still named DriveSmart 50LM, has a full width real glass touch panel and is a far more rectangular design. It’s also extremely tight to crack apart the casing once the screws are removed.
Also mine has the same size of circuit inside, but looks far more complicated that the one here, with no circuit shielding, and a MIC on a length of wire that also needs removing (it just plugs in to a space inside).
I’ll try to find time to write a guide for this other model while I have it.
Thanks for creating this guide all of you :)
It is possible to get them seperate, but the process for fixing them together is complicated. The touch panel is just the thinnest glass layer, and very very cheap from all sorts of places (I don't want to advertise any company names). But to make that glass stick to the LCD panel, requires special UV glue (a very thin glue that only becomes sticky when UV light is applied to it in the right amount) for the right length of time).
It's practically impossible to split your original glass from the LCD panel though - the UV glue is a one way thing, the LCD panel is so sensitive it will 99% break, and the touch glass is also about 1mm thick and very weak.
For that reason, most people just buy a complete screen, and make it into a 10 minute job to refit it.
As mentioned above, the screens are held down by double sided tape, usually made by the 3M company. But most other good quality tape can do the same. The proper tapes are cut perfectly to fit all the little adge bits of the casing-to-screen, and that's all that makes it waterproof.
A thing to remember is, most people loose the charger cover anyway, so worrying about a perfect screen seal from water doesn't matter then I guess as water will just flow in anyway.
The screen isnt really waterproof, its just water resistant, so it's okay for the odd splash, but drop it in a bucket, and it's probably ruined :-( unless the bucket is empty of course ;-) When I refit a screen, i put a 5mm strip of my own tape down the centre (it MUST be the thinnest tape possible!!) and that helps keep the screens in place, but that idea varies from one phone model to another.
