Touchscreen malfunction after changing of earspeaker cover

[Uneksia]

After my iPhone 4s 16GB with iOS 6.1.3 got slightly wet I started having problems with the earspeaker.
I've changed it and it went better, but the volume was still low.
Then I've changed also the earspeaker cover, but when I restarted the phone I've started having problems with the touchscreen. The lowest part of it is almost unworking.
Even if I never changed the earspeaker cover itself before, I'm used to these kinds of work on every iPhone models and I have never had such problems.
Can someone help me?

First of all, the full effects of water damage can take time to appear, and s impossibly what's happening in your regard. It is also possible that you may have reattached the touchscreen improperly. I don't know, but if you haven't already, retrace your steps to make sure you did everything correctly. If you're confident that you have, it may be time to replace your iPhone 4S.

I've changed the full display and now everything is working
