I am profoundly grateful to have received my Samsung Galaxy A42 5G 128GB in Black, arriving in pristine condition—its screen unmarred, battery fully optimized, casing immaculate, and all ports, buttons, and camera lenses functioning flawlessly upon meticulous inspection. Back Market’s exemplary customer support representatives, Anna and Kat, resolved every concern with unparalleled care and attentiveness, particularly as a disabled customer deserving of such tailored service. It is earnestly hoped that Back Market will offer protective phone covers tailored for refurbished devices.

Item arrived on time as promised. It looks and operates like brand new with battery life about 3-days. I could not transfer apps from my old phone due to the age of the old phone but all data (pictures, contacts, etc) loaded in with the sim card from the old phone. Had some trouble connecting bluetooth to my hearing aids but help from Mr Google resolved the issue. I'm a happy camper and satisfied customer

After having my moto g stylus for 3 years, the volume buttons came apart and had to tape it bsck together. I knew it was time for another phone, but i didn't want to spend $300 on something brand new or upgrade to a bigger plan. The phone is exactly as hoe it's described in the description. I will need another phone case, but I really like this phone and it only costed me $156 including shipping. I'm never buying a brand new phone again, I'm sticking with Back Market the next time I need another phone.

The definition of 'UnLocked' does not leave a Refurbished phone shrieking "SIM Card is Not From Verizon" message every half hour or whatever it is. What is left that needs to be nuked, and where is the step-by-step fix speciific to Samsung Galaxy A42 5G?
