Customer Reviews
It is really small, fast and reliable. The service and relacement parts are very good, even when they send them to Europe. I love it to play music, whatsapp, banking or order a taxi. People are surprised when they see it function.
The screen of my previous mobile phone broke, so I bought a new mobile phone. I use it daily as primary phone. It's very perfect for me, a student who don't have time to lose in distractions. This phone has the speciality of the leds on the back. They are very useful to know who is calling me when I am in the library. Also, I had the discount of a free accesory and now I use it for running or in the car.
I hate having large phones, which barely fit into my pocket. I have been looking for a small, yet usable smartphone for quite some time and could not find anything, until 2 weeks ago.
The price I was willing to pay for a phone was up to 1000€ ($1100) and there were no serious options, outside of iPhone 12 / 13 mini (which you can see on the photo), but I dont like iOS and the battery on iPhones barely lasts a day, even if its new.
Finally, I have found Jelly Star, which almost perfectly covers my needs. I was worried about the screen at first, if I will be able to write on it (I am tall and have bigger fingers), but did not have any issues, compared to iPhone 12 mini, which I had to correct myself over and over. I was a bit slower at writing though, I would say I can write at 70% of the speed compared to my 6,5" android phone.
Battery is "only" 2000mAh and I was worried about it at first too, but it does not really seem like an issue, unless you want to stress the phone. When idling, the phone takes about 1-2% of battery each hour, with about 70 apps installed, WIFI toggled on and also SIM card with 4G inserted.
I chose to transfer my files from my previous phone to this one with a USB-C to USB-C cable, which I had to buy (they are not so common, but I recommend you to buy one, it will make your life much easier and clonning faster). I have charged the phone before data transfer to 100% and chose to transfer all my contacts, apps, files, settings,... which was around 50GB totally. Its quite a lot of data and many apps (80 at the time of transfer), so even the CPU was stressed a lot because of installing them one by one. The battery got from 100% to 20% during this "stress test" in 2 hours, after that I just unplugged the cable from the phone, charged it for about 30 minutes (which pumped it from 20% to cca 60%) and was able to just reconnect the cable, press a few buttons on the other phone to continue data transfer and the transfer finished).
Photos taken on the phone are comparable to other Android smartphones in this price range. I dont consider not having more lenses as a disadvantage, if you need this for standard use and dont consider yourself an "influencer" taking photos everywhere, or something :D but even then, the photos are very usable. Daytime photos are completely normal, night time not so much, but thats what I expected anyway.
So, do I consider this phone worth your money? Certainly yes! I am a developer and spend a lot of time on my PC and phone and was looking for something usable, as a minimalist phone, which I can use in case of emergency (to respond to important emails, connect remotely to SSH console, or anything else requiring an Android APP). So if your case is the same, this can be a full replacement of your phone, which you can, but dont want to use (for scrolling instagram, facebook, tiktok and other things all day).
