Yes, if you have simple needs then the Samsung a3 1 still can be used for everyday use. The highlight is its 6.4-inch Super AMOLED screen, which offers good brightness for videos and reading, and sharp Full HD Plus resolution, with rich colours. With a 5000mAh battery, you can expect the phone to last for more than a day of calling, messaging and streaming.The topmost pros are screen, battery, microSD slot for an additional 512GB storage, dual SIM and the headphone jack. The 48MP primary camera also produces nice photographs in the day light and the 20MP front camera is pretty good for video calling and taking selfies.The things they're weak at are the performance and the age. The samsung a31 is powered by the MediaTek Helio P65 processor with 4GB or 6GB of RAM, which can appear to be underpowered for the heaviest of games, applications and heavy multitasking. The charging rate is capped at 15W, and the plastic body isn't that impressive. Also the macro and depth cameras enhance real photography little. It was also released with Android 10 and One UI 2.0, so software support is only available today, and there are some issues to take into account when using banking apps and security.If someone can find a good used samsung a31 for a low price, it's a good back up phone or a first phone for a family member. However, for a key phone in 2026, you'll probably find a newer model of the same price that will provide better performance and software longevity.If I'm researching a gadget, I enjoy reading authentic opinions from techyassist which has genuine reviews on actual devices and also lists products, and then I can purchase from the website when I'm convinced of what it is. It's best to read a few reputable reviews before you make your decision; avoiding being left with a bad impression.
