Had my phone (Galaxy s5 for a couple of years). Absolutely no issues whatsoever. Thinking to myself I could sell the S5 and get a Zuk Z2 with the money and have a new phone with twice the RAM / storage etc - financially it'll be no different
But really what is the point. I can understand if a phone is 5 years + old, back then there was a big difference between a cheap vs flagship phone.
These days each upgrade is only sightly better.
So my question is what is it you do with the phone to justify that 2gb vs 3gb ram or 2ghz vs 2.5ghz, or 60min charge vs 90min charge time. Maybe the camera??
Dont get me wrong tablets - thats a different story, but I'm talking about a regular 5" phone - calls/texts/light gaming/browsing.
Should i keep or get rid of it?
Unless you're truly feeling the need to upgrade don't upgrade.
If your phone is in good working order and you're not feeling any lag in the way you use it, or it's not hindering the way you would like to use a phone it then there's no need to upgrade.
