Yes, the amount of file types is definitely ludicrous (I had to prepare quite a few different logos in different formats so I know [crying] , by the by from my limited experience the DOB maker doesn't like GIFs so much and prefers BMPs) and I doubt anyone here expect you (3CX) to waste precious time/resources on generating exception handling contingencies for them, when there are so many more important things than a logo on a phone that we all need/want.
And I am certain consequences can be dire (which is why one should always backup before changing important/weird/quirky settings, and any sweeping changes, and make screenshots of settings panels) and I do understand that this is a business, and at the end of the day you have to manage expectations for the overall/median/average userbase and that no one wants to spend a weekend restoring a customer's system because someone did something incorrect and tanked the entire enchilada or set it on fire (or gotten Googleslashed ala UniSuper).
But like data protection/information security, compliance, at cetera, you can only go so far to protect users (or CEOs) from themselves.
Perhaps lock it under a submenu "advanced users only"-esque that you have to click to open the panel, display some legalese flavour text that you understand the risks et cetera your phone can be bricked and that you're on your own/your partner's liability, and then tick a box that you've read and understood and agreed it all, then another "are you sure you wish to proceed?" and then it'll display you the thing. And of course have it available to system owners only.
Or when the phone does not load it, it will be the fault of 3CX that it isnt loading. Noone ever blames the phones themselves.
Oh, I rue the day I met a certain Y-brand. I definitely love you guys. <3
I blame Panasonic for destroying themselves and thereby with exiting the market denying us decent phones and by proxy ruining it for all of us.
This is not detrimental to the phone working.
Couldn't agree with you more there. Unfortunately, it's the management's mood that's detrimental to IT admin working.

And management got told phones can have logos. So if they walk around and see some phones don't have logos then critical work has to halt for *ahem stupid ahem* logos.
