So, here's my full list of bugs and feedback for improving Windows 10 Mobile starting from Build 10512 (I'm testing it on a Lumia 920):
Windows 10 Mobile Build 10512 - BUGS AND FEEDBACK LIST:
UPGRADE NIGHTMARE:
- Upgrading from WP8.1 takes very long time, almost 2 hours before I logged in W10M Start Screen on my Lumia 920;
- Upgrading from WP8.1 generates a Start Screen bug where it took very long time for it to load-up. "Resuming..." took an average of 20-30 seconds before Start Screen to load, even after quitting a simple app by pressing Home or Back button;
- Upgrading from 8.1 downgrade Firmware version from Denim to Cyan;
- Lag, slowdowns, crashes and many bugs stayed even after 24 hours of the phone let alone doing its things, and settling down;
- SO: Upgrading as a whole was a very painful process and the only solution for the problems above (and many other quirks and oddness) was in the end an HARD-RESET of the device, WITHOUT restoring an old Backup, but starting new. Very annoying and time consuming;
- PLEASE IMPROVE UPGRADE EXPERIENCE: Both from WP8.1 -> W10M, and from Old W10M build -> to new W10M. Always doing Hard Reset after an upgrade is NOT acceptable.
HARD RESET + NO BACKUP = PERSISTENT PROBLEMS:
- Camera App: swipe from left to right to smoothly load Camera Roll photos is missing. A downgrade compared to stock 8.1 Camera App;
- Many animations are missing: for example opening Edge "Hubs" button, Edge "Tabs" button does not trigger any animation, and the next menu just appears like Windows 95. It happens many times with many OS menus, very ugly and a regression compared to WP8.1;
- Lock-Screen is very slow: it takes 4 second for Time and Date to appear, and many seconds to unlock to Start Screen;
- PIN Screen is visually very ugly compared to both Android/iOS, and should be totally re-done and polished;
- Many apps trigger "Loading" or "Resuming" black screen, while they never did on WP8.1 (for example: Facebook, Tubecast, Twitter, Mail, Calendar);
- Action Center needs transparency like Windows 10 Desktop (or iOS7-8-9);
- Edge renders slowly and crashes on some webpages (example: www.winbeta.org or www.wmpoweruser.com or www.windowscentral.com);
- Edge ABSOLUTELY needs an AdBlocker or TPLs (Tracking Protection Lists) support. See new iOS9 Beta native ad-blocking features. It's night and day browsing after that;
- Edge doesn't have "Google" search engine option instead of Bing;
- Glance is not present in the "Extras" section. It can be opened from Store only;
- Glance shows time only, and partial date or notifications even if enabled fully;
- When clicking the Power button to wake the phone, there is bad flickering showing Start Screen for a brief second, and only after Lock Screen appears;
- Unlocking from Lock Screen still requires 3-4 seconds to show Start Screen (while on black screen + Resuming...);
- HERE Transit isn't available in store;
- Italian new "Maps" doesn't have tranit (Bus/Metro) public transport support, only on foot + car. HERE Maps still has it instead. Please, add it for Italy too;
- Swiping to "All apps" list, and then back to Start Screen reload Background (along with refreshing and flickering tiles) and lags;
- Live Tiles often flickers and/or not update themselves;
- Swiping down the Action Center has a lag/delay of 2-3 seconds before it shows itself;
- Calendar Live Tile doesn't update itself;
- SMS app is VERY slow to open;
- Performance is sometime faster than 8.1.2, sometime lags a lot more. A LOT More performance optimization needed;
- Live Tiles on Start Screen completely stop working after a lot of apps were used and multitasked;
- New Outlook app is slow to open, and hangs;
- LinkedIn is no more integrated in People App.
PLEASE, now SHARE this list inside your W10M "Feedback App" (adding all your personal issues too).
That's the only way for MS to REALLY notices us.
Thanks! :)
