QR code scanning with the Galaxy Fold Z4

So, it's been a while I know, sorry... but I found out something I didn't see much about online on help forums for WhatsApp or Signal.


TL;DR - Cannot scan QR code with Samsung Fold for WhatsApp or Signal windows app connection?

Unfold the phone and scan the code it'll connect up. Scan it when phones closed, it won't. True for both for connecting WhatsApp and Signal Windows 11 applications to Samsung Galaxy Z Fold 4. 



My Galaxy watch gave up the ghost after coming back from a hot holiday this summer (Cyprus, thanks for asking... was amazing) It was stuck in a never ending boot loop and even on flat battery, when it came back to life, it looped. 



When I got home, I sent it off to Samsung for repair and they mailed me back saying;


Now, from memory this is pretty close to the cost of the watch so I picked myself up off the floor and politely declined and said send it back, which they did. 


When it arrived back, it turned on and worked. RESULT! 

But I figured there's a possibility that it will go bad again anyway, so I decided to look at what was new and sure enough, Samsung were about to drop their new Galaxy Watch 5 and their new Fold Phone. 

I've always kinda wanted a Folding phone so thought hell, lets just upgrade the lot. So I traded in my beloved Samsung S20+ BTS edition, with its purple heart (even though I literally paid £200 ish for the screen and back cover to be replaced about 4 months ago) #DOH and my now working watch. 

The phone swap was simple, it all came packed nicely and arrived a day before official release and Samsung's Smart Switch did the work so download that if you have a new Samsung and an old one going out. It doesn't do ALL the apps but it does enough. 

Signing in to WhatsApp and Signal was all the normal process but this is where I get to the point. No matter what lighting, what display monitor or what angle I tried to connect up the phone to the PC app via the presented QR code, it just wouldn't recognise it. 


I could use the camera of the phone in normal camera mode and it would scan but it would know that it needs an app to do anything with the result. I couldn't find anything on line for how to fix this on WhatsApps site or Signals and pretty much gave up as a bad job. Then I saw someone's post online about the camera quality on Samsung's and comment about the larger screen doing something differently...  


So with nothing to lose I booted the Windows apps up again and unfolded the screen.. 


BOOM, connected straight away. 


So, if you want to sync the Windows applications with your mobile chats, just unfold! 👍

Syncing your Nokia contacts to your car via Bluetooth

Image
So, over on the various forums I've frequented, and with the interest in mobiles and cars, I've been asked this question many times. It nearly always revolves around someone having a Nokia Phone and a problem with them syncing that phone's contacts to the car for communication via the dash or the head unit. There's not a problem with calls, its just this issue with being able to see your phone book. So if you are one of those wondering, "How the hell do I get my contacts to my car from this Nokia N8?" ... or Nokia N97 or whatever Nokia you may have picked up, this will help. To quote myself from the 1st time I wrote this out (I thought this was worth salvaging from the old blog posts) You need to download a file from Nokia that is called "810 contacts Download Application" and just for you, this is the link . Find your phone or equivalent and get that version. If you have the Nokia N8 the 5th edition version works just fine, even though you're on...

Xperia Play Screen Cracked

//thanks to the android app this is now the 3rd time I've written this. This morning, whilst sitting in the lounge a phone notification came through, so I went over the the stand that my phone was on to check it. To set the scene, this stand was a MASSIVE 2.5 foot high. As I picked up the phone, it span in my hand a little and slipped. Gravity did its thing and the phone went directly down. Opps I thought, and that was all I thought at that time. I've had many phones that I've dropped. Dropped on carpet, dropped on tarmac, dropped over 13ft from a shirt pocket up a ladder (that was a Nokia) down on to concrete ..... and they all survived with nothing more that a dint on the casing or in the case of the X6 that skipped down the tarcmac, a slight nick out the glass itself. So on to this morning. After the HUGE fall of 2 foot, clearly something met the very edge of the PLAYs screen and this happened. The hardest thing this could have hit is my pen lid, (which was metal) which ...
