Update: After day 18, I finally got my phone back from service center. Widevine issue is fixed.
So, 18 days to flash widevine certification keybox.
So, before you guys go to service center, keep in mind that it may take more than 2 weeks to get your device back.
Black crush issue is still the same. That is the only issue with this phone right. Other than no phone accessories is available on sale in india. I have been waiting for Aero Active Cooler 3 to go on sale ever since I bought this phone, but can't find it in my country.
This is phone is great at gaming, and probably is the best gaming experience on Android phones, but black crush issue is nightmare.
