Wonantorna Tempered Glass Compatible with Samsung Galaxy A21s Screen Protector, [3 Pack] [No Bubbles] [Easy Installation] Tempered Glass Screen Protector Compatible with Samsung Galaxy A21s

Does the job.

Very easy to install

Nice thick screen that seems to still have a good touch screen sensitivity. No obvious instructions regards fitting the main screen although I have fitted a few so managed that bit OK. The air gap reducing liquid was a bit different though. Followed the instructions but if you want to be picky then you can still make out a slight line about 2mm in all around the edge. Also managed the get some on the screen when wiping the excess off. This left it a bit blurry to start with... Hopefully it will be ok. Good value as it includes 3 of everything..

The size of the glass is too big for the A21s and overlaps the sides of the curved screen. This will accumulate dust and eventually peel off.The size should've been smaller to fit the inside edge of the curved screen ORIt should've been designed with curves to fit the screen properly.

It is easy to install and it last for long

Does not stick on edges and really easy to scratch...Get 1 good 1 for this money instead of those .

Found I lost contact with the screen , they are very thick, not what I was expecting and I prefer the peel off film type ,The upside there were no bubbles . Once on, but trying to close a page on my phone took several attempts till I removed the screen .I just found it fiddly to apply probably wont use the other ones , but I didn't think they were expensive so it was worth a try .

Installation will inevitably reduce sensitivity of the screen - I have installed several times... not because it is bad - it does the job. Its also a pain when the air gets stuck and does not come out - irrespect of using the goop supplied.
