Fix and improve touch screen sensitivity issues on iPhone after glass screen protector is installed
2022-01-03
Better late than never. Just after detecting two small scratches on my new Apple iPhone 12 Mini 128GB screen I immediately decided to put a screen protector. Tempered glass option was my first thought choice because it is most likely more scratch resistant although slightly more fragile. Apple iPhones are expensive, and it is best to do whatever you can in order to ensure longevity. To be honest I should had installed the screen protector even before the first scratches, anyway better late than never.…

So I wish you a much better year 2021 than the unfortunate COVID influenced 2020.…

I decided for the upgrade because the router behaved sometimes in a really strange manner. WAN interface was marked as down anyway the VPN was up an running. Which is a contradiction. Long story short, the Asus got bricked with the official firmware upgrade done in an official upgrade your firmware button press.…
