While everyone marvels at Samsung's latest and greatest Galaxy S series, for many people, these high-end devices are either unattainable or downright...
Unless Samsung removes the 3.5 mm jack and microSD slot as well, it won't equal the iPhone!
Though seriously, I have a spare Samsung A series phone lying around. I used it for couple of weeks and it was unstable(like it often froze and restarted in the middle of something). I dunno if it was happening because I was using Goodlock modules on that phone which Samsung doesn't officially support. But it was lackluster. The audio jack was barely outputting loud enough sound via IEMs( same set plugged into other Android phones produced louder sounds).
I know this is supposed to be an entry level handset and I appreciate that Samsung is giving 4 years worth of security updates(many mid level Chinese OEMs won't give that), but the hardware is a little too underwhelming.
The A series has a lot of variance within it now. Personally I think anything from the A2x up is pretty good (the A25 had an Exynos chip, a 120 Hz AMOLED display and 5 years of security updates) but those beneath are more akin to what the J series used to be.
Usually, the reason my phone restarts is due to using virtual RAM and having the phone under memory pressure. Disabling or reducing the virtual RAM made the phone snappy at the cost of increased App reloads. Choose the balance you like. The hardware is not strong enough for multi tasking anyway. Assuming it has RAM plus.
I'm speaking from experience of using galaxy A22 5g which had 6GB of RAM and 128GB of storage. But, this is still true on my realme smartphone with 12GB of RAM.
