Some screen protector sharing here for s21 Ultra.
1. Tested with original basic plastic screen protector come with the new phone for a week. Then saw the youtube video about that plastic protector only support up to level 3 scratches. Then syarted to order screen protector.

2. Purchased TMax tempered glass and installed according to the video. Specially handle the fingerprint area according to video. User experience not so good. The FP cannot read if I just wash hand with soap or sanitizer, or sometime just hand too dry. I thought is weather making my finger dry bcoz if I apply abit lotion/water, whatever form of moisture, it can read the FP. Then after 1 week I thought of wanted to reapply the protector again(I got spare UV glue) but accidently drop the protector on floor from table height after removed from phone. It cracked.

3. Without having any choice, I experienced the screen without any protector for 1 week until today. The FP super duple great experience, never have such condition as dry finger that can't read the FP. Just a gently touch without any pressure, 100% detected. Really like the way it unlocked, fast and precise! But the drawback is the naked screen easy to coat with fingerprint grease and dust. Make the screen always feel dirty. Of coz also high risk without protection.

3. Then my mocolo brand tempered glass arrived today. Installed with special handling on FP area too. It work for my S10+ but not on S21 ultra which I apply both phone with same method today itself. My S21 Ultra totally not able to register the FP with this screen protector. Checked again the mocolo glass, it is significant thicker compare to Tmax glass. End up I removed it again.

Now still searching which tempered glass to go for. Whitestone Dome is overly expensive which not in my consideration at all. Being using it on Note8 last time. It is good but too expensive.

Already tried coin trick, alchohol pad+ thumb holding on the FP trick too! My guess is the glass quality not premium enough and affecting the detection. Being study alot on how to apply tempered glass properly from youtube. So far no perfect solution yet...

I did the same, everything ready before my preorder arrived. At the end preorder availablefor pick up 2 days early somemore. I'm using spigen camera protector + nikkin super frost shield. Still waiting for spigen thin fit to be available in malaysia.

Not seeing any different after install the clmera protector. Photo as clear as it is.

It come with 2 pieces. S21 Ultra camera module quite big, I feel more secure with the protector.

Received tge galaxy fit today.
