Dear Customer: Hello! When you see this letter, it means you are looking for the right phone screen. Although we are now a new store and a small store, in fact, we have been engaged in the mobile phone screen industry in China for several years and are very professional. Please confirm your mobile phone model before you buy (if you cannot confirm the mobile phone model, you can contact my customer service for confirmation. Due to the time difference, the reply may be a little slow, please be patient, our customer service will reply you as soon as possible), Generally, we will complete the delivery within 2-3 days after you place an order and pay. Each screen will be repeatedly tested 3-4 times by professional staff before delivery (to ensure that every screen is perfect). After receiving the goods, do not rush to install, please connect your mobile phone to test first, and then install if you are satisfied (because of the long distance, you must first make sure that there is no damage during transportation). When installing, we recommend that you find local professional staff for help. Because the LCD screen is difficult to install and easy to damage (problems such as poor touch, black corners, colored lines or black screen), of course, you can also replace and install it yourself. After all, replacing the screen is an interesting thing (by overcoming many difficulties, successfully restoring the phone to normal, happy), when you decide to replace the installation yourself, you can go to the Internet to see the tutorial (the tutorial on the Internet will help you a lot), I believe we will be your most correct choice, but also the best choice for your mobile phone! Thank you so much for clicking our product links, happy shopping and happy life!
