I am using 4G A52. So far so good. I think it's already one year +.  This is one of the few mid range phone which has OIS. Can't live without Samsungpay. And I don't want to pay crazy price for phone since mid range pretty much does everything I want and the A52 camera is already very good unlees you blow up photo on big monitor to compare with other phones, you won't see any significant difference. Probably my next phon also A50 series...lol
