If I may suggest, look up liquid screen protectors. I'm using one on my L1020, and it seems to perform as advertised (against scratches, fingerprints, reduction of glare/reflection). This is not a tempered glass screen protector, but in my opinion liquid screen protectors are in many ways better than tempered glass add-ons. Specifically, I've got Kristall Liquid screen protector on my L1020 and a handful of other phones that belong to those in my immediate vicinity. Have a look at the reviews and video demonstrations online. One of the things I like about it is that it can be applied on any device - unlike tempered glass protectors that need to have a specific shape/size for each model - considering that the L1020 is a bit rare and old, finding L1020-specific accessories at this point in time may be a bit of a challenge.
However, if you insist on tempered glass screen protectors, you may move along untouched by my post. :smile:
