In today’s digital world, our mobile phones are more than just communication tools—they are our lifelines. And protecting them with a mobile screen guard has become a common practice. But what if we told you that most people actually make basic mistakes while applying or choosing a screen guard? Mistakes that not only reduce screen guard life but also harm your phone screen in the long run.
If you are someone passionate about mobile repair or even considering learning the skill professionally, understanding these beginner mistakes is crucial. In fact, if you master this one simple area—screen guard handling and application—you can start building trust with your future customers.
At Vaishno Mobile Training Centre in Delhi, we make sure our students understand even these small but important aspects of mobile repairing. Let’s dive deep into the top 5 screen guard mistakes and how you can fix them today!
1. Choosing the Wrong Type of Screen Guard
Not all screen guards are created equal. Beginners often pick the cheapest option without understanding the difference between types like tempered glass, PET film, and TPU.
Comparison Table: Types of Mobile Screen Guards
Type | Protection Level | Flexibility | Clarity | Cost |
---|---|---|---|---|
Tempered Glass | High | Low | High | Medium |
PET Film | Low | Medium | Medium | Low |
TPU | Medium | High | High | Medium |
Fix: Understand your customer’s need. For most users, tempered glass offers the best protection and clarity. Learn about material science in our course to recommend and install the right one.
2. Not Cleaning the Screen Properly Before Application
Dirt, dust, and fingerprints are the biggest enemies of a smooth screen guard installation. Beginners often skip this step or use a regular cloth, leaving particles behind.
Fix: Always use a microfiber cloth and alcohol-based cleaning wipe. Apply in a dust-free environment. In our practical sessions at Vaishno Mobile, we simulate clean room environments so students can practice like pros.
3. Applying the Screen Guard Without Aligning Correctly
A misaligned screen guard looks unprofessional and can even affect screen sensitivity.
Fix: Use the hinge method:
- Align the guard and secure one edge with tape.
- Flip it over, clean again, and slowly apply from one end.
- Use a card to remove bubbles.
This method is taught practically in our live workshops. You’ll learn tricks from industry experts that can’t be found in YouTube videos alone.
4. Ignoring Air Bubbles and Not Using Proper Tools
Air bubbles are a big no-no. Many beginners try to push them out with fingers which leads to cracks in the screen guard or even dirt entering the screen.
Fix: Use a bubble remover card, usually a plastic squeegee. Apply screen guard slowly, pressing bubbles outwards. For stubborn bubbles, lift that part gently and reapply.
At Vaishno Mobile, we provide each student with a complete tool kit, including these bubble removers, so you always work professionally.
5. Forgetting to Educate the Customer
This one is often missed even by trained technicians. Once the screen guard is applied, educating the customer on how to maintain it is essential.
Fix:
- Tell the user to avoid excessive screen pressure for 24 hours.
- Recommend using a soft cloth to clean.
- Inform about lifespan and when to replace.
We teach soft skills and customer interaction techniques at Vaishno Mobile. Because being a good mobile technician is not just about repairs—it’s about offering complete service.
Bonus Tips to Make Your Mobile Repairing Career Stand Out
