Why doesn't touch work?

Samsung Galaxy S4: Reset but Touch Screen not responding

1. If you recently got your screen repaired, it's possible that the repair was not put on correctly. Take it back to have them redo it.

2. If you replaced the screen and digitizer with aftermarket parts, I've heard of parts received DOA (dead on arrival or with issues of their own) being installed. In that case you may want to try getting parts from a different Seller

2. If your screen is not cracked and you did not damage the phone, and the phone is still under warranty, call Samsung Tech Support to see what they think. 1-800-SAMSUNG. You will need to mail it to Samsung for review. If it's deemed your fault it may cost up to $200 to fix +$30 to ship back to you +about that much to ship your phone insured to them. Or, take it to a local repair shop to save $$. If you have insurance on your phone from the Carrier, get them to check it out. It could be the touch sensor or the digitizer

3. This is a suggestion from online, however I don't think it will help, but it doesn't hurt to try. This suggestion is normally used when a tablet with a fixed battery that cannot be removed won't turn on.. Try depleting your battery to zero.. Meaning keep the phone on until the battery dies and the phone powers off by itself, take the battery out, hold down the power button with the battery removed to help the phone deplete any leftover energy in the phone. Put the battery back in, charge the battery to 100%, and then try powering on the phone after that. Doing so will soft reset the battery kind of like reconditioning it.

Cant use my touchscreen

Hi there

First remove the protective cover (if any) the protective cover may be preventing the touch screen from working properly

Oil or residue from your hands can build up on the screen and interfere with the touch screen function.You should clean the screen with.

To do this, turn off your phone and disconnect any cables. Put a small amount of water on the corner a soft microfiber cloth, like those used to polish musical instruments.

Gently wipe the phone with the damp cloth until it is clean. Dry and lightly polish the screen with the dry end of the cloth. The towel should be damp,

. When the Phone is completely dry, put it back in its case and power it on. Do not put water directly on your Phone

If all these still do not make the touch screen work then you should have your screen replaced.

Samsung i780 Ringtones corrupted

I have exactly the same problem and also noticed that Windows Media Player was not starting on my Samsung i780. I Googled a bit and found the reason. Media player is somehow using the Application Data/Volatile folder. When I looked to that folder via File Explorer I saw about 300 folders. deleted them all and after a soft reset all problems gone. Hope this helps.

Turn on problems

Your phone is working fine, you only have to increase the brightness. If you press "phone disconnect call button" and hold it for a while (like you do to lock the phone), then you will see the screen. Now you have to find a way to "blindly" go to systme->backlight->brightness and just increase the brightness.
It is a bit tricky but solves the problem. You can "lock" the phone to see the screen as often as posible,
