Greetings.
Recently I had a problem of sudden shutdowns of my Microsoft Lumia 640XL. The diagnostic message after restart is somewhat like “SD card corrupted”, with a possibility to run a check. However, running the checking utility does not change situation at all, except a possibility for another shutdown and making all SD-based apps inaccessible.
I have run a check of SD on my computer; it seems perfect. Desiite that, I replace the “problem” MicroSD with a fresh one and re-install the most useful apps; the error continues. A hardware diagnostics reveals no problems with an SD slot or other hardware components; I suppose a Windows Phone problem. Which measures I can take to remove or just disclose a source of this problem?
Best regards.
