Recently i've formatted the SD card for storage issues, setting it as internal memory.
I've transferred the possibly transferible apps on the sd card a week ago, but now the system crashes the app and doesnt' recognize the card...

Please check if there is some problems with your SD card, Just insert it into another phone.

There are numerous of things you can do in this situation
1. Make sure that you have your card as FAT32 for 32gb or below and exFAT for 64gb and above (maybe considering to reformat it by your computer)
2. Try to plug it in another phone and see if its work.
3. Try to reformat the card in our phone after step 1.

Please post your any of your updates and concern below. Thank you.

Neither the other smartphone recognize the sd card (Kingston device).
Is it beacause i've formatted it for the blackview?

I've found an old ScanDisk sd card, and it works. But now i have to reinstall all preferences and apps.

Blackview never stops to disappoint me. I'll choose another rugged smartphone brand.

Every phone encrypts the SD card used in it. If you want to use an SD card in another phone, you'll have to format it again. This behaviour can be found in EVERY phone brand. Nothing to do with Blackview

The only other smartphone i've ever had, was a Samsung S3, and the SD card never stopped working.
And i hadn't to format the card to transfer some apps onto it.

Why i can't transfer all the apps, but only certain ones?

PS: After the factory reset, the blu led has begun to work again (it stopped blinking previously with no reason).

Using the SD card as an internal storage is not recommended, it may cause weird issues as you can see here:

Using it as a portable storage is the best way.

This isn't a brand related issue.... just open the link i posted.
In every Android phone (of every brand!) using an SD card as an internal storage may lead to weird issues.
