If you have any kind of problem with the screen of the iPhone 6s or 6s Plus, don’t worry. It is unusual for these to fail, even less if they have not suffered any damage. That is why we analyze here the possible failures that may arise, as well as the recommended solutions to attack them.
Blurred screen of iPhone 6s

Despite continuing to be an exceptional problem, among the screen failures this is one of the most common. Whether it is because the entire screen is blurred or a specific section in which the image is moved, the best thing to do is to calibrate the screen. This calibration must really be carried out by experts, so you should go to a technical service that has tools available to carry out this action.
If the screen is green

Having the green screen or any other color variation on an iPhone 6s or 6s Plus could be related, again, to a poor calibration of it. However, it is also possible that this is due to an accidental blow to the screen. Many times we can drop the phone on the ground or get hit against an object and present no apparent problems at the moment, however some part may stop working over time due to the wear caused by the accident. Be that as it may, we again recommend to go to a technical service to check the screen and they can offer you a repair estimate.
Solution to software problems

Obviously a screen is pure and hard hardware, but you have to know that sometimes the software can play a trick on you and for some type of failure it shows the screen with inappropriate colors or some other type of problem. The best solution to this is to restore iPhone without backup .
The fact of not making a backup is fundamentally because if the problem resides in some type of file that you have on your phone, it will continue if you restore with a copy. In any case, we recommend making the backup before carrying out this process, since in case of not solving the problem on the screen, you can restore and, this time, load the copy. To format the phone it is always recommended to do it with a computer, although if you do not have one you can do it from Settings> General> Reset and clicking on Delete content and settings .

Price for iPhone 6s screen

If you finally have to change the screen due to an internal failure of this or for having suffered an apparent breakage, the price that you will have to assume at Apple is 171.10 euros regardless of whether it is the 4.7-inch model or the 5-inch one ,5 inches. If you have contracted AppleCare +, this price will be 29 euros , also on both models.
If you are looking for a cheaper solution you could change the screen yourself. This option is not recommended if the phone still has a guarantee, since this would be automatically canceled when handling its components. It is also not recommended to change the screen yourself if you do not have the skills and sufficient knowledge for it. If you finally decide to do it, you can find very cheap packs on Amazon in which in addition to the screen the necessary tool kit is included, although it must be said that the quality of the screen is not the best as it is not an original part.
If the iPhone is under warranty

It has been several years since the iPhone 6s and 6s Plus were launched on the market, but because there are stores where they are still sold, it is possible that yours was a recent purchase. If your phone still has a legal guarantee, the best thing for any failure is to always go to Apple. You can request an appointment on their technical support website and if you do not have a nearby Apple Store they can come and pick you up at your home to take you to their laboratories. Of course, this has an additional cost of 12.10 euros that could be added to the possible repair in case it is not covered by the warranty. In the event that there is no nearby Apple Store or that Apple does not operate in your country, it is recommended to go to an Authorized Technical Service (SAT).
