If you follow the guide provided for applying the seal and making sure the seal is water tight (using heat gun, coins and heavy books) it will work. I accidentally dropped my phone into a bath of warm water the day after I replaced my screen and it worked! No water damage at all. That was 18 months ago and I’m typing this message with the same phone right now.
Thank you so much for the advice on this and the suggestion of heating coins and using books. I did as suggested and three weeks later my phone was knocked into a bath of water. It had a mophie case around it which helped bit I immediately fished out the phone, turned it off and dried it. Tapped out water in ports, removed the SIM card and then placed in front of a fan to dry put for 24 hours. I wanted to wait longer but I needed my phone for a long trip so prayed and turned it on. It was fine. Nothing wrong with it abs I can only thank you foe your suggestions to improve the seal that made the difference.
I did with a heat gun instead. I found the i opener not helpful.
I echo what everyone is saying here, the spudger just isn’t good enough for this and neither is a pick. The razor is the best way to go. I tried using a very sharp penknife blade and managed to damage my LCD (somehow!) and the bezel so I ended up having to buy a new screen display as well as a new battery. Think twice before doing this. Be prepared to shell out for a new screen just in case it goes wrong. You’ll also need the heat gun (the iopener was useless). If you do need to buy a new screen, make your life easier and get one with the speaker, forward-facing camera, home button, etc., already attached (you can then replace the home button) or you’ll end up having to transfer all these from your old display.
Thank the stars that I looked at these comments. I managed to do this and transferred the home button successfully. The pick is not good enough to do this job. The suggestion to use a new playing card helped. I also found that if you use a single edged razor to ply apart the bezel from the screen then when you apply heat with the heat gun the bezel will melt and bend a bit out of shape allowing you to use the playing card to lift the home button strip away from the bezel. The adhesive on the old home button strip was enough to stick it to the new screen bezel without having to buy new adhesive.
I found this to be completely useless. It didn’t help at all. I had to use a heat gun instead. Waste of money.
