Why do consumers decide against buying a new phone in favor of switching screens?
Replacing a phone is expensive.
A brand-new flagship phone costs several thousand yuan or more. Customers find it easier to accept that changing a screen only costs 30–40% of the price of a new phone.
Performance on mobile phones is still adequate.
Daily video browsing, WeChat conversation, news reading, and document processing are all flawless even though the S21 Ultra is a model from a few years ago. The user feels that their phone doesn't need to be replaced.
Data migration challenges
Reinstalling apps, moving photographs, and logging in again are all necessary when switching phones. It is more convenient to fix it and keep using it because many consumers are reluctant to experiment.
Quick circulation in the used market
In areas like Latin America, Southeast Asia, and the Middle East, the updated S21 Ultra still has a high circulation value. Screens for equipment refurbishing are still being purchased by the rehabilitation factory.
Installation Notes
Avoid tearing off the film prior to testing.
Turn on the computer, connect the screen ribbon cable to the motherboard, and verify that the stylus, touch, fingerprint, and display are all functioning correctly. Remove the protective film and start the installation process after making sure everything is operating as it should.
Prior to securing, align the cable.
Only tighten the cable interface when you hear a "click" sound after aligning it with the motherboard socket and gently pressing it down. Non-display or touch failure may arise from improper fastening.
Examining fingerprint cables separately
The S21 Ultra's fingerprint cable is rather tiny and easily missed. Before moving on to the next step, test fingerprint unlocking after installing the screen to make sure it functions.
Clean up the residual glue in the middle frame
After removing the old screen, the remaining glue particles and impurities on the middle frame need to be cleaned up. There may be black spots or poor touch when there are clutter on the new screen.
One time adhesive bonding
The screen backing adhesive is a disposable design. Before closing the lid, it is necessary to confirm that all functions are normal, and then remove the adhesive protective film and stick it together. If you stick it on and then remove it, the backing adhesive will become ineffective.
Try before installing to avoid rework
After passing all tests, tighten the screws and close the cover. After installation, if problems are found before dismantling, it will take time and may damage the screen.
