A:Answer 5-7 years old.... probably not ?
P.S. I won & still use DAILY Motorola DroidMaxx mad in y.2013, still perfect voice & texts, only problem is carrier refuses to update software, obviously dueto age & few owners of such old thing, so my WebBrowser also refuses to update & many websites became somwhat criplled, but mostly usable, can you believe? year 2013 it was sold (made in 2012), still amazing battery life & display in Black/Night/HighContrast mode....
I tried to TradeIn - DroidMaxx doesn't even comeup on allowed dvices list for TradeIn ANYWAYs, you just goto Tradein webpage, donot buy for real but start/simulate processes by clickign tradein & follow thru menus to enter old device & if you don't see your son list of acceptable tradeins then nope you can't trade in, but 5-7 years old MAYBE acceptable th unlikely, my (10+ years old) is definitely unacceptable, checked
