how do I retrieve deleted messages on my Huawei p9 lite.
Hi jennifer. I'm pretty sure your carrier can help you with that. Contact them and ask to recover the deleted messages. Also, there are softwares that claim they can retrieve deleted messages like FonePaw (link), I highly suggest checking the reviews of these apps before using them if you plan to. If none works, you can avoid this in the future by using apps like Easy Backup & Restore (Android app on Google Play store).
