Hey, how's it going? I would like to know if you guys have any knowledge about the use of tempered glass films on the screens. 
Are they able to affect the good performance of the pen?

I just bought a Lenovo P11 Plus with the Precison Pen 2 and I'm a little bit worried of having a tablet with no screen protection. So, if you have any 
knowledge on this matter, please let me know. 

Thanks in advance.

Greetings and thanks for raising this inquiry.

On a personal note, thicker tempered glasses offers extra protection to our devices but may have its screen not to be too responsive to touch especially when using a pen. With that, I advise you to contact the tempered glass' manufacturer to confirm its compatibility on the tablet. I'm sure and confident that other members here can share their recommendations and experiences about this inquiry.

Aside from that, I strongly recommend you to visit our Lenovo SmartFind site or contact our Lenovo Sales to check the available accessories your Tab P11 Plus can use and their availability in your region as well.
