After updating to the 20170708 firmware the problems have disappeared!
The phone plugged into the cable, not original, off, has the normal alarm clock, both in the original charger and USB port of PC (better than version 6.0).

Problem solved!

Thank you

After the last update (20170708), I noticed that when rebooting the cell phone the system performs an error scan on the card, and simultaneously displays the message that the storage has changed. Soon in the sequence asks if I want to change the storage location, that is, every time I reboot the sys...

hi, I´m sure the only way to solve your problem with SD Card and WhatsApp is to do a factory reset. Myself I´ve had problems with sd card and WhatsApp - I solved it with a factory reset.

I'll try the configuration. And as for the answer of the problem 1) the SD memory card always has to be chosen when starting the cell phone. I want to leave as standard the storage always on the external card, but choose this always, this is annoying me a lot.

Sorry, I forgot to mention that the alarm clock does not work when the phone is power OFF when connected to the charger. In version 6.0 the same problem happened only when I was charging power off and connected to a USB port of a computer, in the original factory charger there were no problems, now ...

The last version (7.0) the alarm clock does not work with the unit charging in the original source.
The previous version (6.0) only had this problem when I loaded it through the USB of the computer.

Help me!
