I updated to pie and now when I receive text messages and calls my phone doesn't vibrate even though I have it set to vibrate when I receive calls and messages. Does anyone else have this problem and does anyone know how to fix it?
Hi @Kelly8, I am sorry to hear about this.
Have you been able to carry out a quick test on your phone in order to see whether the vibration functions as intended or not? This can be done using the support app. Find and tap Settings > Support > Xperia Tests > Vibration.
Another good idea is to clear data for the app in charge of sound and notifications. this will reset all settings for the app which might do the trick. keep in mind though that if you have chosen a specific ring tone you will need to set this up again afterwards.
In order to reset the settings for the audio settings, Find and tap Settings > Apps & notifications > See all XX apps > Tap the three dots in the top right corner > Tap "Show system" > Audio settings > Storage > Clear data > Restart the phone.
Try this and keep me posted on how it goes! 
I went and I had did the test and I felt no vibration. Following that I had went and cleared the audio settings and reset. Unfortunately my vibration still doesn't work.
Thank you @Kelly8 for your quick reply.
In that case I suggest that you try to to perform a software repair using a computer and Xperia Companion. Please note though that a software repair will erase all user data, so remember to do a backup of your user data first.
If the software repair do not manage to improve the vibration function, My suggestion is to get in contact with your local support team in order to have the phone sent for repair. If you have any questions regarding the service, such as routines, warranty and consumer laws, these type of questions are best answered by your local support team as well, as they vary between markets.
I hope that helped!
