as for today( January 2015) my answer will be.. my next phone will be android lollipop..1st there no leak/news about upcoming flagship/high end model for Lumia.. to date still use 2 years + 920.. still this 920 2 years old camera can beat latest mid range phone..os wise..WP today much stable but to catch up with iOS and lollipop need much help from big apps developer which WP lacks very much..and for android phone like other say... many android phone with good spec priced less 1.5k such Xioami..already use iOS platform..so nothing interesting for me...

Hey guys, what's up? My 1020's warranty has expired, and I've been thinking on getting a new Lumia.. either 930 or 1520, and we obviously don't know when 1030 will come out (IF it does anyway).

So, which is a better deal? The 1520's larger screen (but not amoled as 930), larger batt, and microSD slot... or 930's higher ppi, corning gg3, smaller size (easier one-hand operation)?

And do they both have Glance screen as per 1020? Thanks. 

whoops my bad its 1020. mixed up 1080 (tv resolution lol) but yeah internet sharing is definitely not a problem.

sharing internet using USB cable is a function called "tethering"

to answer your questions : phone firmware updated to the max, windows updated to the max. auto update already set but also manually force update to check updates. USB port is healthy. OS healthy. sharing internet via bluetooth wifiu?tethering is a different technology but I did test out internet sharing (phone hotspot) which works as expected on my laptop which is on windows 8.1

if you wanna say my phone/usb cable/pc/OS/firmware got prob, i do IT at my workplace so i do have access to many various devices/PCs. when internet goes down, i do help my colleagues tether their phones to their PCs if really needed to and what i found was ANDROID phones can tether to windows 8.1 pcs with no issue. but when I wanna do the same? FAIL my windows phone cant do that, how embarrassing is it to be an IT guy using a high end windows phone but cant even do tethering when your colleagues phone which cost 1/3 or 1/2  of my phone can do something mine cant?

you can try googling "tethering windows phone", you will find no real results where you can see people asking on how to tether but people respond ignorantly by teaching them to use internet sharing (hotspot/wifi/bluetooth). you can even find some people even  suggesting that this feature be added in on windows phones.

retarded level max. windows phone OS? no thanks.
