苹果官方于2015年9月25日正式发售iPhone6S A1688/A1633机型。 此机型的修理方式与先前几代差不多, 需要螺丝起子及撬棍工具。 同时也适用GSM or CDMA/16, 64 or 123 GB/ 银色, 金色, 深空灰色, 玫瑰金色等机型。
A Yellow dot is typical on poor quality backlights on replaced screens. If you have not had a replacement screen and the screen you have is the original one another possibility is that if the phone has received a blow (typically from a drop ) it may well have created a small dent that has placed the screen under pressure thus in turn placing the backlight under slight pressure and that is showing through with a yellow patch.
An easy way is just to connect a replacement screen but dont seat it back in place. Boot the iPhone and see if the yellow patch is gone if it has then power down and disconnect the battery and screen again. Then examine the housing any even tiny dents etc can cause the issue. If you dont have the tools to remove those dents its quite cheap to get a new housing
