Solved my own problem eventually. I have 2 TalkTalk email accounts on my Samsung phone, both working fine until recently. Then they ceased to work over 4G while continuing to work over wi-fi.
A month ago I referred the problem to Vodafone, and they reset Secure Net, and the accounts work OK again until yesterday.
There is a related thread here
After discussions with Vodafone and Samsung, I discovered that my IMAP settings were for security "None" on port 143. Why had it ever worked?
So I set the port to 993 and have to choose between "None", "SSL", "SSL (Accept all certificates)", "TLS", and "TLS (Accept all certificates)".
According to the relevant help page the choice should be "TLS". On this Samsung Galaxy phone running Email client Version 188.8.131.52 the security option which works is "SSL".
Who would have thought it?

That’s right. So it is a bit confusing when the TalkTalk instructions clearly state to use TLS, when actually SSL is what works. Anyway all sorted now, I just posted this so others might learn from my discovery.

Mine is a Samsung Galaxy J5 (2017) aka J530. Not sure if that counts as an "older" Samsung device. It confused Samsung Technical support, and it doesn't exactly match the characteristics of the J5 (2017) depicted on Samsung's web site.

That'll be me then! The older Samsung devices, for example a Samsung Galaxy Note 4, has the security types that you mention e.g. SSL or TLS. Newer Samsung devices specify SSL/TLS for incoming mail security.
IMAP Port 993 and Security Type SSL is the correct setting to use for your device.
