Transfer data from water damaged phone

[Sofia12]

Hi, my poor Google pixel 3a has suffered water damage from having been in a very steamy room. The screen is all black and bit blue and cannot be used. My question is, when buying a new Google pixel phone, how can I transfer all my photos and folders and WhatsApp messages etc from the broken phone to the new? Instead of ordering a new phone online, am I better to order it from the shop and ask them to help me transfer everything? Is that something the staff at O2 shops are able to do? Tried calling them but no answer.

Thanks

Everything should be backed up to your Google account so will all be present on new phone after you login with your Google account details.

I just logged into my Google account on the laptop and it's all there. Baby pics and all! Thank God! 

Thanks a lot
