Wanted to say a big thank you to all the people who have contributed to this thread, It's been really useful for an old fart in his 70s who's returning from the dark side after a journey of many years. iPhone 4 to iPhone 6s then to SonyEricson.
A diversion into the world of Samsung with the S7 followed by my current Honor View 20.
I've ordered the 12 Pro in Blue which should arrive on Friday.
In the meantime I've dug out my old 6s and have been reaquainting myself with the world of IOS. I've been following this discussion and have ordered and received screen protectors from LK, a Ringke Onyx case from a helpful link from another poster on this forum and also a Wallet case from Ocase. ( I know it covers the screen but I've got used to having my Bank cards and travel pass in the C/Card slots )
The LK screen protectors came with a protector for the camera lens but my instincts tell me that fitting one might degrade the optics as it's an extra reflective surface in front of the lens.
I ordered ( and cancelled ) the Apple magnetic charger as I wasn't sure if the charger would stay attached when the phone is taken off charge. ( I have a nice wood effect platform wireless charging stand that I used on my S7, it was easy just to plonk it on the stand and let it charge when at my computer desk )
Current plan is with Plusnet Mobile, 4 Gig for £7 per month on a rolling one month contract. No 5G yet where I live.
Really looking forward to Friday and hope the swap over from my View 20 is as painless as possible.
So thanks again folks, a great forum!
