Dear All,
Well first of all after a long anticipated time the Windows Phone 10 Preview have arrived .. however i was too disappointed to so many reasons.
I will list the major problems that i faced after updating my Lumia 1520 to WP10:
1- When you are done with the update .. the actual boot time of the device is longer u will have to wait for about a minute each time you restart your device. My boot times are near the same (40-50 seconds)
2- The Pin Problem . your phone will get frozen once u enter your pin for the first time and that is what happened .. i removed the sim did a hard reset the problem worked fine .. however i lost my data. I have no issues with PIN entry
3- there is no EMAIL app that is clear .. have searched for few hours and found nothing on how to add a new email. Outlook email is present
4- The contact app is really buggy .. very slow ... and crashes way too often .. The people apps, alpha and standard, have not crashed for me
5- some of the previous apps will give you a crash and exception errors due to memory allocation issue. I have not experience this issue
6- Your phone touch screen will freeze .... No freezes so far for me
7- The power draining is incredibly annoying your battery will go from 100 to 50 in about 2 hours .. After 6 hours, my battery is at 77%. Others milage may very
8- The actual call app is very buggy and it takes u forever to answer a call and call. Although I do not like the layout of the new call app, I have not experienced any buggy-ness or slowness
9- the one thing that i hated the most is the keyboard .. it seems that there is a layout problem and the keyboard is super small ... I agree
10 - the glance screen cannot be turned off .. Same here
11- you will be lost as many of the settings are hidden inside another which is annoying and frustrating once you want to fix something every time. I personally like the organization of the Settings, better than the never ending scroll of WP8+. It does take some getting used to, though
12- many apps do not work and if they do they are super laggy. I have not experienced this issue. But, I do have 5 apps that will not update/install (OneDrive, Kinectimals, pin.it, Pimp my Band, device hub)
13- YOUR LUMIA 1520 will GET HOT ! REALLY REALLY HOT ! My 1520 is not getting hot, but did a little initially while on the charger and updating. I am unsure is that was usual or not
14- The camera app is laggy and very slow. Lumia Camera is as fast as it was in the previous 8.1 dev preview build
15- the vibration on the 3 buttons you have is constant and u cannot turn it off which will drain your battery even more That is true. I didn't even notice that, since I leave the vibration on always. This bug is reported
16- the home button becomes non responsive in many cases and you will be forced to do a reboot for the device. I haven't experienced this issue
17- the notification bar gets stuck while taking it up or down . so you will be forced to do it twice for it to work . I have not experienced this issue
These are some of the problems i have faced with my Lumia1520 after the update and now i am rolling back to 8.1 ....
Hope that gives u a heads up ...
