PIN Code not accepted anymore

[Monjara]

Hello everyone,

I've bought my Sony Xperia XA2 in France a month ago.

Tonight, the PIN Code that I have always used is not accepted anymore by my smartphone.

Two days ago, there wasn't any problem.

Yesterday, I went to a party with neighbours, but I don't think one of them as neither the skill nor the will to modify or hack a PIN Code.

Is the PIN Code modifiable via the Google Account ?

Yet my Google Account didn't inform me of any intrusion attempt. I will secure my Google Account nevertheless.

Can somebody help me ?

Now I can only rely on the fingerprint to unlock my phone.

So it is very strange,

After many unsuccessful attempts, I plugged the phone and it restarted by itself, although the battery was loaded.

Then, the PIN Code worked as it used to.

I've just read that it could happen though.

Does it come from an application ?
