The new music app in 8.1 sucks, download the music hub tile app to use the old one until the 8.1 version is improved.
How big is your SD card? I have an 8gb one and it's as speedy as it was on 8.
Been using WP8.1 on my 520 for several months now and I love it better than WP8. I did a hard reset BEFORE installing the WP8.1 Developer Preview. After the update, it felt like a new phone... Months after, no problem with the performance of it.
I just rolled my 520 back to WP8. The 8.1 DP had it running like a bargain basement Android -- trash. Throw in crap UI/UX changes and made it easy for me.
I have updated my 625 to Denim. Ever since it is laggier than ever. Same thing happened when I updated from Cyan to Black. So now it is 3 times laggier than wp8 Cyan. Hurray! Good job MS! WP the best! The phone crashes and restarts on a daily basis. I can't even open news sites with many images.
It was definitely worth updating, because:
- I have a higher version number for IE
- I would have cortana, word-flow and cool things if I were 'murican (but I am not, and I will never be able to use it, cause fk the other parts of the world)
- Some fancy stuff
- My friends can joke about me using a Denim spray as a phone
I hope some MS nerds will send a reply telling me how to reset my phone and reinstall and reset everything. WHOOAAAA best advice ever! Thanks! Just one question: do you reinstall your whole pc every time there is an error? Perhaps you should reset your life as well
My conclusion: WP is an unborn baby. Only a marketing bullshat. A lie.
