Yesterday, i updated my lumia 525 to winphone 10 preview from winphone 8.1. After that, my phone can’t access settings, my alarm is crash,…
However, when i Hard reset my phone, it’s worked perfect, but i lost my data like messages, apps, game except my photo cause i store it in SD card. But when you sign in by microsoft account, you will get all back. But i don’t know if i lost some data !
Finally, my phone worked normal, some time it lag but i don’t care. =]]
Hope it will help you. :3
