Samsung Cell phones dont last

i have been a Samsung fan for years.. my first samsung was an S4.. it bombed out before my next urgrade was available, so i got an S3mini that i had to buy while waiting for my upgrade. i then got the S5 mini for my son, that lasted.. i then got a S6 , S7 that bombed out and got a J2 to keep me going to my next upgrade and S8 x2 which one bombed out and had to get a J7 now to carry me to my next upgrade.. scarry thing is, my upgrade is in 1 and a half years away so effectively it lasted 6 Months.. i have to say out of the 7 Samsung S series phones i got.. 3 of them never made it from one upgrade to the next.. IE they didn t even last 2 years.. that close to a 50% success or failure on their side, how ever you want to see it.. so sorry Samsung, my next upgrades on my cell contract will not be Samsung.. i need reliability not something cool for a few months just to spend money on a smaller phone just to be able to remain connected for the remaining time on my cell contract ... its a pitty, i really liked the Samsung
