Allenater Arena Apprentice 8 Great phone for every day tasks Posted: Jan 18, 2022, 12:12 AM Phone owned for more than a year

I've owned this phone for over a year. I really like it a lot. The only problem I have with it is when you stream music. It's will slow down and freeze after a few hours. To avoid this I have to clean out the cache. For every other purpose the phone is great. A little clunky processor but for what I paid for it not bad.

SimonTheBest Arena Apprentice 9 Good Qty Phone - Samsung A51. Edited: Oct 05, 2020, 8:55 PM Phone owned for less than 3 months

I gotten the A51 becos my last phone went dead on me. I have been using it for the last months or so, I am quite happy with it. Many reviews had said the chip set (Exynos 9611) is outdated and slow. But I find it okay for my use. I have the 6GB RAM, which helps alot. One more note to consider....the A51 is going to get updates for 3 years....which is a good surprised for me. The only fault of the phone is the onscreen finger print scanner...it is rather slow but I learnt that having registered 2 same fingers on one scanner helps to improve it. But I am hoping that Samsung will do an update to fix the problem. As for another issue, is the battery......The A51 is quite a beast in consuming battery....And this too, i hope it can be fix with updates.

wickedwilly Arena Master 9 Great phone for the price Posted: Jun 24, 2020, 8:36 PM Phone owned for less than 3 months

Have been very happy with this as a smaller 2nd phone since day one. Considering the price and this is in the budget/mid-range it is highly recommended all-around phone. The comparable Pixel takes better photos, but for almost everything else this is better. Compare with the iPhone SE and this is a much better phone in most areas and a far better buy.
