Review: Just what I was looking for - Perfect phone for me, the screen is small but fine if using swipe text, The size of the display stops my constant casual web browsing like on my old smartphone and limits me to looking at what I need to know. You can watch video no problem though. the NFC feature is really useful. Battery life is good, I charged it overnight 13 hours ago, used it for 2.5 hours streaming music and texting and still have 50% left. I love the size, so easy to fit in my pocket, I can stream my music while running and in the car etc no problem. at all, The usual Apps work fine so its reduced my smartphone use but kept me connected. the IP68 rating is great for the beach life in Cornwall. I did try the Nokia 800 tough before this but sent it back due to being so slow and glitchy, this phone is twice the price but worth every penny.
Review: Fabulous little phone. - I bought the Jelly 2 which had software issues. Unihertz advised me to buy the Atom and I am pleased I did. It is as fast and does everything my Galaxy A8 did. The fingerprint reader is a bit iffy but the face recognition works well. It is small for shopping but I have a mediapad at hope for that, the typing is difficult, fat thumbs and a small screen! But the talk to text works quite well for sms and Whatsapp . The battery lasts the day. If you're sick of large phones this is a great alternative.

### ⭐⭐⭐⭐⭐ Fabulous little phone.

### ⭐⭐⭐⭐ I love it. Not for everyone
*by F***A on 11 January 2025*

This is great for my needs. I've been resisting having a smartphone for years because a) they're massive and I can't be bothered carrying one and b) I know I'll end up scrolling endless nonsense and wasting hours. The Atom is tiny and fits in all my pockets with ease; it does everything any other smartphone can do so is great for messaging, maps, checking emails etc. But it is quite a faff to use so I've not been tempted to do any casual browsing. Keyboard is fiddly but predictive text does most of the work for you. I get 2-3 days out of the battery depending on use, but I have turned the brightness down, battery saver settings on, and I switch the phone off at night. Camera is fine for snapping this and that, probably not going to win any photograohy prizes with it. The only thing that's really annoyed me is that once every few days, it shuts down for seemingly no reason whatsoever and has to be manually restarted. So if you're waiting for a life-changing call, maybe don't trust the Atom to be there for you! (Or just keep a really close eye on it)
