The last phone i bought used in 2 weeks time starting rebooting on its own and eventually got into a boot loop, out of warranty i managed to sell it "Working as is, best for parts" which needless to say resulted in a big loss. Now if the P2 XL is an ideal size and if the warranty is infact 2 years, then i would understand why so many support going with it than P3XL if you dont care about the updates. For me, im too paranoid now to buy phones used, ill sell mine (which are always in mint condition) but that experience made me scared enough to not take the risk again.
