Suggestions for an alternative to a Galaxy S7

[Russell]

I need to replace my Moto G4 Play, screen broken in many places and running so verrrry slowly.  I chose a Galaxy S7 as it is pretty much the same size weight etc but much more highly specced and were available as NOS for a resobably price.  However the first phone that I received and its replacement both had the back cover coming away from the case, possible a swollen battery??  I think I will ask for a refund but what other phone to go for?  I would like a 5.1" or close phone.

Thanks

I've been very happy with a Pixel 4a which is about 14cm if that's not too big. Great camera, battery and sound.

Larger than I would prefer and well out of the price that I would be willing to pay for a phone.  But thanks anyway.

Security updates for older phones aren't produced, and they won't run up to date OSes (planned obsolescence).  That's the issue with buying anything more than 3-4 years old.

So how much do you want to spend? Second hand Samsungs are usually not cheap. The S7 is about 7 years old, so will be stuck with an older OS version etc.
Unfortunately there's not many modern phones that are actually small, apart from a few niche brands.
