People tend to buy devices with the hope that they will last for a long time. I mean no one wants to buy a device which is going to fail you half way through. You want to invest in a solid product that is effective and works well. This is why a lot of people tend to invest in buying an apple product as these devices tend to usually last a lot longer than other products. But of course you must keep in mind that nothing is going to last forever and neither is anything that durable. There will be situations where you could end up shattering your screen or getting cuff marks on your phone or something. In this situation you need to figure out on how to fix it.
To start things of keep in mind that most people when they buy they apple device on a carrier plan you are stuck with that specific device until your plan is finished. That is to say you get the subsidy only for the device you buy with the plan. If you damage your phone to the point of no repair you would have to end up paying the entire amount for your replacement device. So make sure that you take care of your device properly as iPhone Repair is not something that is cheap. You would end up spending a lot of money if you end up shattering your entire screen as screen replacements are very expensive. There are certain home remedies that you could attempt with easily available ingredients. They are supposed to work to a certain degree especially for like scratch marks and scuffs. If you really bust it up you for course will have to replace it I doubt there any home remedies to help you with that.
Of course as long as your warranty is valid you can get it fixed easily but there are certain types of damages to the device that normal warranties don’t cover. You could of course go to a trustworthy iPhone Repair shop. Of course if you have warranty still better to go to an apple store as if you go to any other place your warranty becomes void. Hence if you are going to end up using another place make sure that you are okay with your warranty becoming void. in my opinion even if they are a bit expensive it would always be better to go with the professionals at an apple store as they will give you good service and fix it up properly. All in all just be careful with your device and if you do need to fix it is always better to go to an apple store.
