Will a cracked phone screen damage the phone s usuability?

I just cracked my iPhone 6s today and my heart is crushed. I have not told my parents this yet, and I do not think that they will let me repair it/buy a new phone.

If I just purchase a plastic screen protector and leave my cracked screen be, will it damage my phone itself in any way?
Should I even bother getting it fixed?

Get the screen thing and it won't hurt the phone

Usually, a cracked screen won't interfere with the phone's normal operation. It just looks bad.

However, depending on how and where the phone is cracked, it can cause issues with the digitiser (touch screen) and may make things randomly happen; like random apps opening, etc. In addition, the glass can cut your fingers so it is a safety hazard, but since you will be buying a protector, then that's not going to be much of an issue.

Take it somewhere & pay to get the screen replaced. Then buy a case to protect it, nothing pretty but protective.

  • Will water stains on my iPhone screen damage my phone? Some water managed to get under my iPhone screen through a crack on the screen while it was raining. My phone works fine as of now, but there's a light blue stain and another white stain which look like dripping water under my phone screen. I'd really rather not pay for a repair on new phone and I can live with the stains, I'm just worried that they'll damage my phone. Do I need to dry it out or is it unlikely to cause a problem? TIA

My IPhone 5C screen is cracked (a lot!) everything else works and there seems to be no other problems other than glass falling out of the screen. Do I need to replace the screen with an LCD Touch Screen Digitiser or just replace the glass?
