I bought an Edge to Edge tempered glass from good mobile accessory shop and got it fitted in my Mi10 by a professional technician there itself.After a week or so there developed one or two air bubbles in the screen and they began to grow big covering half of my screen.So I approached the shop again and they repalaced the glass with a new one.After about 2 weeks there began to develop air bubbles again and they growing in size gradually.My had not dropped anywhere from me or others.So what is the reason for this?If I replace the tempered glass with a Screen Protector film,can the developing of air bubbles be completely prevented?Aso will this actually protect the phone screen glass from breaking in the event of a fall?Can anyone suggest a good quality Tempered glass and good quality Scree Protector Film?
