Guaranteed Original Equipment Manufacturer LCD Display With Touch Screen Digitizer For Huawei Nova 2 Plus - with unique 45 days replacement for manufacturing defects.All our products are thoroughly tested but you might run into some unforeseen problems if you do not use an expert technician. So, we strongly recommend servicing under expert technical supervision. Self-installation without required skills can be dangerous to the screen/device. Do not remove screen guard or warranty sticker until you are completely satisfied. Screen guard removal means acceptance of the product. Warranty is voided once the screen guard is removed. A technician can test the product easily by connecting it to the motherboard of your phone & test it fully. When you are certain that everything is working fine then your technician can install it permanently (we will be not responsible for any damage done by technician/repairman). Please keep the item in original condition and don't remove warranty sticker & screen guard.
