I read that Motorola is slow at updating Android, but that’s not really a big concern to me
The previous Android (A13) had a major bug on many devices that allowed skipping the entire lockscreen and unlocking the phone without entering the device's code. It remains unfixed to this day in those models where A13 was their final Android version and the manufacturer stopped patching it before a fix was released.
Motorola is so slow with providing updates that even if such a problem were patched it could take months during which your only workaround to remain safe would be to put the device in a drawer.
Evidence of these delay issues with your very own Razr: Motorola only just release the first A14 version a few weeks ago in July even though that came out in 2023. We are close to A15! And your Razr is a flagship device! It's supposed to receive updates until 2027 but apparently customers don't even know if it will ever receive Android 15.
A cheap iPhone SE from 2020 still receives a new iOS version on day 1 like all the flagship iPhones. A cheap a series Pixel still receives a new Android on day 1. How is this joke that's Motorla acceptable and worth your money?
If you decide to stay Android, I would recommend a folding phone if you like the idea of it.
You mean a flip phone. The main issue I found was that anytime I wanted to use the phone for any reason at all I needed both hands to flip it open. Not a problem sitting at my desk but on the go it got old fast. With my smaller iPhone I can take it out of the pocket with one hand, it unlocks with Face ID immediately and I can swipe up with the thumb of the same hand and even type quick replies.
Foldables that aren't flip phones were also interesting but the only really good one I found was the Pixel Fold and that will only get 2 more Android versions (A15 and A16) but costs more than my iPhone did. If it were the same price as the iPhone with the same support times then I would have preferred it. But paying more money for worse support isn't something I consider and there's no Pixel Fold 2 and I needed to buy something.
People often ask why there needs to be a new iPhone every year and that the differences are really small but at least when I do need to replace my device there is a latest version with full update length available. With other smartphones you never really know if there's going to be a successor at all. Sometimes the entire phone design is turned upside down and it's not what you expected and wanted.
