Redmi Note 3 (Snapdragon) Hangs and Restarts

Hello,
I bought Redmi Note 32GB Snapdragon variant (my first Mi phone) a month ago and just after 10 days or so it started showing hanging problems. If it was a random once in a while hanging issue, I would not have had any problem but when the phone slows, after a couple of seconds it freezes then all I can do is restart it into fastboot mode or wait for it to switch off after around a minute so I can restart it myself. I have tried installing MIUI 8 Global Beta and after that back to MIUI 7 but both seem to have the same problem. I also went to the Mi Service Center where they installed their own update again and said it will not have issue anymore but it still shows the same problem.

I have googled for a similar issue on this phone but I seem to be only one having it yet. I have no idea what to do so please if you know anything about this issue then please tell me.
Regards,
Varun

Flashable themes with secure boot (with PIN) hangs

I've recreated this problem with a number of themes on a couple of different ROMs so I'm hoping someone can help me find a workaround or a way for the theme providers to bypass this issue. I keep my HTC 10 encrypted using the normal means, and when I selected a PIN I enabled the secure boot option that requires a PIN. To be clear, if you are using this feature then when you reboot or cold boot after the initial boot animations it flashes up a screen that says "preparing settings" (or something like that) then you get an off-white screen with a prompt to input a PIN to decrypt. If you succeed, then it goes back to the boot animation and then it continues to boot to the initial login, which looks like your lock screen PIN entry and requires a PIN on first boot, even if you have fingerprint enabled. So secure boot has 2 PIN entry requirements., and it almost looks like 2 boots to get into a fully operational system.

Anyway, if I flash a zip them (say, one of the venom official themes, pureview, etc.) then it will get to that screen that says "preparing settings" and it will hang forever. It never allows me to input the decryption PIN so it can continue boot, and I have to reboot to recovery and restore. Can anyone help me address this?

Thanks!
