I just finished a chat support session regarding the loss of GPS functionality on mine and my wife's Galaxy Note 8 phones (SM-N950U). The support person was familiar with the problem and it seems most likely to have been caused by a software update.
The Note 8 was released in Sept. 2017, so it is only three years old. This GPS issue has been dogging us since at least June 2020 and I see no fixes in sight and Samsung advises that the phone will NOT receive an Android 10 upgrade. Unfortunately it seems us Note 8 users have been abandoned by Samsung.
One purchases a flagship product costing around $1000 each and this is the treatment we get? This is the Galaxy Note product that succeeded the Note 7 disaster! Sorry but please explain, why I would ever purchase another Samsung phone?
Hey Shona, to be clear, the GPS works but often when using car navigation it will stop working and show us moving at 0 MPH. Turning location off, then back on remedies the problem temporarily. Have done a factory reset, updated everything, cleared caches, storage, etc. I see many people complaining of the same issue, glad you don't have it.
