It's one of those that's not only able to close some questions, but also raises new ones by questioning certain answers many assumed were written in stone. Even though it can come to a dissapointment for some to know that leaving questions unanswered may seem strange, there's also a silver lining in knowing that Alan Wake's storyline is first and foremost that of a TV series format within a game. In the other half of the presentation department (graphics and sound), "The Writer" is able to hold up with the stiff competition on the marke...

Why Phone Touch Works Randomly After Water Damage or Screen Change

When your phone’s touchscreen starts working intermittently or erratically after screen replacement or minor water exposure, it’s a sign of interference or damage in the touch circuit. This issue can range from simple grounding faults to deeper motherboard-level problems. Let’s uncover the major causes and working fixes for this frustrating problem. 💧 1. Moisture Under the Screen or Touch Layer Even a small drop of water trapped under the new display or near the touch connector can cause ghost touches or delayed response. This happens because the capacitive touch system detects electrical charge through the screen — and water interferes with that signal. Fix: Power off the device immediately. Remove the screen (if recently replaced). Dry all components with a blower or silica gel for at least 6 hours. Reassemble only after confirming there’s no moisture residue. For safety, see our post on how to stop apps from listening to you — it also explains why ...
