My Samsung Galaxy S4 Zoom phone has been automatically upgraded to firmware version: PDA:NH1/Phone:NH1/CSC:NG1 (BTU), and ever since it reboots randomly, the zoom lens extendes and retracts without warning and the phone has become totally unreliable.
Is there any way to down grade to the original firmware version?
Thanks for your help.
Thank you so much for your help. Whilst I could not get the previous version of the firmware to work on the phone, however I did find a more recent version that the version I was having problems with, which had not automatically downloaded to the phone.
I have now replaced the firmware with this newest version, the phone appears to be working OK and hopefully over the next few days I will be able to see if this has fixed my problem.
Once again many thanks for your help.
