    •  Small Yet Powerful     

    Jelly may look cute but it packs a punch! It uses a quad-core of 1.1 GHz processor up to 2GB RAM & 16GB ROM.     

    • Dual SIM-Cards 

    We are travelers and we are business people just like you. Many people prefer to maintain more than one phone number and switching SIM cards to do so or when traveling is a hassle. Jelly makes it easy with dual Nano SIM card slots.

    • Enjoy the Fast 4G Speed

    Jelly supports most of the 4G network carriers except those with CDMA.

    Working well.

    Everything is good, the camera, the touch screen are working well, the only problem is the battery, I include all the functions of the charge save.


    Coming from dedicated Mp3 players similar in size and the predecessor the Posh Micro x240 (in hot pink

    pros -the killer size, serves a 'niche' market -2gb ram is excellent beating out my old galaxy s3- 16gb storage and micro SD slot is there. -2 sim slots work well -pretty fast- android 7.0 feels really nice here. -ONBOARD FM RADIO! thank you Unihertz team for including this on your phone! It's not the greatest- but it records and I'm super happy its present. -camera/video? not the greatest but I'm happy its there for sudden improvements when its needed and nothing else is around. a VAST improvement from Posh, flashlight is on there too I love this feature- so cool to have a flashlight on such a tiny phone. completely missing from posh. -Build quality considering is pretty good. care and attention went into the design. I loved how the posh felt in the hands and I'm happy to say this is mostly the same. -Full android 7.0 experience. Apps work much better then they did before on the posh-faster and more optimized. -call recording is there when you need it. -answering and taking calls can be a pain... but greatly improved from posh. love it love it. however, its not a prefect backup phone. some things can be worked out. Even some improvements can be done with what we have now. some examples Cons -the BIGGEST FAULT would have to be the battery, a HUGE downfall for MANY phones over time. Processing power has gotten ****** good ****** quick but lithium ion battery tech is still the same as ever with the improvements only being in size. Even though a great improvement from the Posh, the 950 Milliamp Hour(mAh) (over posh 650mAh) however it does not quite optimize it even very well. I think the new 7.0 and some built in apps really drain it and make it inaccurate at times. I have personally charged intermittantly to see big (60ish%) numbers only for it to fall during listening to a podcast an hour later. the battery drain really sucks the usability of this tiny rig. Users report rooting and cleaning up of certain apps and disable of wireless communications to greatly increase the capacity of their jelly phones. Unihertz please release a bigger battery with a new backcover and case to compensate, -users report bad GPS feeds... I haven't seen this so far. -a couple of apps can be glitchy, again its likely the battery saving doing its job. -NFC missing... fair enough it may be even more draining for battery use. -taking out the battery to install micro SD/SIM cards is a pain in the rear. Confusing and hard to figure out- quick guide wasn't clear on this. I preferred the posh mini sim/side loading design here- back cover had to go but the battery could stay in. minor gripe in design it functions otherwise after installed. -NOT recommended use for heavytexting/webs surfing. However in a pinch it DOES get the job done- I like to use the smart keyboard pro app to talk into my phone to send accurate text messages when needed.

    They fixed the GPS !!!

    GPS functionality is poor if not useless. I wanted to use this phone while I ran to track GPS and heart rate (Strava or Wahoo apps) while I listed to Spotify. It was purchased to replace my Samsung Galaxy SIII which was larger and had an older Android version (4.3). Also purchase the arm strap and wore like a watch - hardly noticed it while running and was able to observe app which was great. My old SIII worked excellent except for the fact I wanted something smaller with an updated Android version. Unfortunately the GPS functionality of the Jelly Pro is unacceptable. Accuracy is terrible as can be seen in attachments. Shown are back and forth runs using the Jelly Pro and SIII - Good data should follow the road. The Jelly Pro appears to be off as much as a quarter mile. Its useless for what I want it for. I also down loaded the GPS Test app and found the GPS functionality to be erratic compared to the SIII. I spent a good amount of time trying to get this phone to work including a factory reset but was not successful. GPS Problem is also reported on Unihertz Kickstarter site. In short I wish it would work for its small size is unnoticeable while running. Nov 23, 2017 UPDATE: Unihertz has been very cooperative in solving this issue and their tech support is great. There has been some improvement with the recent phone update but not there yet in regard to the GPS issue. They are still working on a fix. Dec 14, 2017 UPDATE: Unihertz provided an update that has significantly improved the GPS functionality. GPS test app now consistently sees more than 10 satellites - as much as 19 with clear sky. It is also more stable (GPS app no longer loses all satellites). Will update again after I test while running. Unihertz is focused on fixing this and has been very helpful to date. Dec 23, 2017 - They fixed the GPS - Best accuracy I have ever seen in a cell phone - See 3rd attachement.

    Nice, small, functional

    It's ok, easy to use despite of super small screen; smaller definitely than most of other phone coming last 10 years and getting bigger and bigger to the point of fablets. Frankly, I really don't need 5.5 inch in my pocket while going out to sit with friends. It comes without charger, but apparently any other USB charger can be used. Battery with moderate to full use can last a day, and with just a few calls a day and not too much fiddling with wifi, gps and all that stuff, and with airplane mode enabled over night, battery can last up to 4 days.
