How can I fix iPhone 14 GPS issues after iOS 18.4.1 update?

I've been having the exact same issue for a good few weeks on 18.4.1

I’ve been using Waze for years, never any issues. Lately (iPhone 16 pro max on 18.4.1) been having GPS connectivity issues every single day. I’ve done everything! Reset network settings multiple times, reset location & privacy, reset all phone settings, got my network provider (Three mobile) to reset my network connection from their end, still same GPS issue on ALL my sat nav apps, Waze, Google maps & Apple Maps! Deleted and reinstalled the three apps and same issue.

Last night I backed up and erased my whole iPhone, still same issue today! Apple has checked my GPS antenna and all hardware on my phone, they said all working fine.

Sorry but it’s gotta be the software. Have an appointment with Apple tomorrow morning, will get them to plug my phone in and check the phone, will see what they say 🤷🏼‍♂️.

Hey sorry for late reply been non stop!

So Apple plugged my phone in and scanned, they said they could not find any faults, which did not make sense to me.

The technician decided to replace the motherboard (logic board) with all chips and processors obviously.

luckily my phone is under warranty! Motherboard replaced and seems to be all normal since running GPS apps! Every time I drive though I turn on my sat nav apps to keep checking incase.

Apple recommend that after phone being completely erased, just incase it is a bug in the backup copy on iCloud, don’t directly restore iPhone from last backup, set up phone as ‘new’ then choose last option (3rd option down).

Your photos, contacts, notes etc will all

still re-download onto your phone, you’d just have to rearrange your settings and redo passwords all apps, banking apps etc, which is a bit of a schlep.

Yeah no worries. No you wouldn’t be covered as initial phones warranty is 12 months unless purchasing more.

It’s not about wiping everything to set up like new to kick the GPS receiver back into life, it’s more about the fact that if there is a bug on your backup copy on iCloud, when you redownload your backup back onto current or new phone, that bug downloads with the backup copy from iCloud.

I thought I’d try redownloading my last back up ‘with the bug’ a few nights ago just to see, driving on motorway today it happened again even with new motherboard! It froze saying in red on top ‘no gps signal’…

So annoying. I now know it’s a bug in the software OR in my backup. I’ll have to erase again and start again then test again.

Apple don't replace motherboards, partly because iphones don't have motherboards, but also because they only replace batteries, screens, or complete phones.

Make an appointment at the Genius Bar to have it diagnosed.
