Iphone 5s cracked screen

I drop my iphone 5s just now and the screen cracked. When i went to those shops that sells accessories for mobile devices they said the could repair my phone for $160. When i went to the Singtel shop it told me that they will repair my phone for $300+. Why is the Repair on Singtel cost more?

Lots of reasons. It's still a new phone. They know you will have to have it fixed and you probably do not have insurance coverage on it. Supply and demand basic economics of business. BUT they might provide you with a warranty for the repair and do it correct and professionally. IF you can I would contact Apple or find an Apple store in Singapore and ask them who they prefer or recommend. Sometimes they authorize certain dealers.
Hope you get if fixed.
Best luck.

No clue

I would take it to the apple store, have a professional do it because those places may screw it up.
