Chosen Solution

Well i dropped my iPhone 4s lately and it did some pretty good damage, anyone got an idea to fix it? I do think its a screen problem but I don’t think I can fix it myself.. The problems are that apps you can see with double tapping homebutton has some weird whiter lines going from left to right, also happens to text from games, and there are some black pixel on the upper side of my screen

Sounds like you have damaged the LCD assembly and will need to replace it You can purchase a new one here: iPhone 4S Screen Guide on how to do the replacement here: iPhone 4S Screen Replacement
