This tiny phone packs a big punch! I purchased the Jelly 2 to try and reduce screen time and practice a more minimalist approach to smartphones. It has served that purpose very well so far! The phone is much quicker than my old LGV20, and the battery life is superb for such a small device. The extra thickness is noticeable but worth it for me personally for the extra battery life. This phone does everything a normal-sized smartphone would do, including running all my apps (music streaming, navigation, email, messages, banking, stock trading, calender, radar, etc.) in a much smaller package that is just more fun to use. I also love that in includes a headphone jack, IR blaster/remote, and even a fingerprint sensor. Can't ask for much more than that in a tiny 4G smartphone.
Speed; snappy processing/navigation speeds, probably due to such a small screen and fewer pixels. But I'll take it! Absolutely blasts past my old LGV20, which was a flagship in 2016 and has a Snapdragon 820 chipset.
Camera; I'm going to include this as a pro for this device since I wasn't expecting much from a phone this size/price point. I was pleasantly surprised however, and most photos have turned out pretty decent. Good lighting helps. Whether close up or taking nature shots, the camera isn't "great", but it is certainly acceptable. (See pics for reference)
Fingerprint Reader; after registering the same finger twice, I get nearly 100% success using the fingerprint reader. That's a good thing, because it's my preferred method of unlocking the phone. I also like that it was kept on the back of the phone, rather than an in-screen reader.
Calling; I was worried about the mic being so far from my mouth while talking on the Jelly 2, but so far I haven't had to repeat myself. I am able to hear the other person, and they are able to hear me just fine. The earpiece speaker may be a bit quiet if you are in a noisy environment. I did notice "HD" on the screen during my last conversation, so apparently the phone is capable of HD voice calling as well. Has not dropped any calls yet.
Battery life; I put this phone to the test my first few days, purposely charging the phone to 100% and using it until it literally died in my hand. I can stream music, search the web, use navigation, send texts, and even make short phone calls for hours before the battery fully dies. I do wish the battery was removable so that it could be easily replaced once it begins to deteriorate. Hopefully Unihertz will offer a battery replacement at a decent price when this does inevitably happen. I would estimate I'm getting about 4-5 hours of screen-on time, with an overall battery life of about 12-14 hours with moderate to heavy use. Not bad for such a tiny phone!
Non-removable Battery; it pains me to see that the battery is non-removable. This means that when the battery eventually loses its ability to hold a charge, you will have to either send the phone back to Unihertz for a battery replacement, or just replace the phone entirely. Since the phone is not a uni-body design, and is at a lower price point, I can't understand why we are not given the option to remove the back and pop in a new battery ourselves. To me, this is a major downfall of the Jelly 2 over the long term.
Speaker Boost - Go to Settings > Sound > Advanced > Sound Enhancement; now toggle on "BesLoudness" to get a noticeable increase in speaker volume.
Face Unlock - Go to Settings > Security > Face Unlock (enter your pin) > Enroll Face; now let the camera familiarize itself with your face, and you now have the Face Unlock feature on your tiny smartphone!
Increase Keyboard Size - Go to settings > System > Languages & Input > Virtual Keyboard > Gboard > Preferences > Under "Layout", Select "Keyboard Height" > Choose "Extra Tall"; you have now maximized the size of the on-screen keyboard to allow for easier typing.
Overall, the Jelly 2 is a great little phone. It's powerful/speedy, has a decent camera, good call quality, great battery life and an adequate display for its size. It will do everything your larger smartphone will do in a smaller package. I do worry about the build quality with the aforementioned jiggly plastic buttons on the side. I also wish it had removable battery. But these are small gripes compared to the overall device. I'm glad I purchased the Jelly 2, and it has even become my daily driver for now! I look forward to seeing what Unihertz puts out next. Would highly recommend the Jelly 2!
