My widgets became corrupted after a while. What is the problem?

File corruption in microSD cards will most likely to happen when it gets interrupted while it has an ongoing write procedure. This can occur due to almost any reasons like power interruption, sudden card removals, etc.

There also a low chance that file corruption can occur when the file are frequently being read. The probability of this happening can be further reduced by using Industrial microSD cards that has 'Read Disturb Prevention' technology.
