Hello Musicgold,

If the issues you're having are indeed software related, factory resetting the devices should revert them back to original and fix the problem(s). That said, those issues you describe sound more like hardware issues than software.

I understand Fido might have sold the phones to you, however, any warranty repair would be done through LG. If the phones are out of warranty, your option would be to have the repair shop replace the motherboards. You might consider contacting LG directly. If there are widespread motherboard issues with the phones, they might have a motherboard replacement program.
Hope this helps 
Cheers
Hey there @musicgold,
Are you perhaps referring to the LG G3?
