Using a tempered glass screen protector on a cracked screen of the Redmi Watch 5 Active can be a temporary solution, but it may not be the most effective or recommended approach. Here's why:
1. Protection and Durability: Tempered glass protectors are excellent for preventing scratches and minor impacts, offering superior durability and scratch resistance with a hardness rating of 8 on the Mohs scale[2]. However, if the screen is already cracked, tempered glass might not provide adequate protection against further damage or water ingress.
2. Installation Challenges: Applying a tempered glass protector on a cracked screen can be tricky. The protector may not adhere properly to the cracked surface, which could lead to bubbles or uneven coverage. This could compromise the effectiveness of the protector and the overall user experience.
3. Long-term Solution: If the screen is cracked, it's advisable to replace it entirely for optimal functionality and to prevent further issues like water damage or screen malfunction. Replacing the screen ensures that your watch remains fully functional and protected[3][5].
4. DIY Repair vs. Professional Service: If you decide to replace the screen, you can attempt a DIY repair using replacement parts available online. However, if you're not comfortable with DIY repairs, it might be better to seek professional assistance, although service centers may not always provide support for such repairs[3].
In summary, while a tempered glass protector can offer some protection, it is not a substitute for a proper screen replacement if the screen is cracked. For a long-term solution, replacing the screen is recommended.
