A decent starter phone for a tween, Virgin Mobile’s LG Unify is the best phone (and the only one you should consider) for its Virgin Mobile Custom service. But it’s not the best prepaid phone in the $100-150 range. While it’s compact and has great battery life, we were disappointed with this version of the phone’s performance.
The LG Unify is actually just a rebranding of the LG Optimus F3 ($29.99 at Amazon) , which is out on Sprint, Virgin, Boost, T-Mobile, and MetroPCS. We gave a positive review to the Optimus F3 when it came out on Sprint 15 months ago, celebrating it for its extremely long battery life. This model has highly customized firmware to support the Virgin Mobile Custom service, and it turns out that also means it has somewhat different performance.
Read the Optimus F3 review for a basic rundown of the phone’s performance and capabilities, and our full Virgin Mobile Custom review for the details of the new service plans. Here, we’ll focus on what makes the Unify different from the Sprint phone we looked at last year.

Voice and Performance
We thought the Optimus F3 was a very good voice phone on Sprint, but something’s gone wrong with the Unify. I had poor voice quality when testing this phone on Sprint’s network, with a fuzzy overall sound and distortion at top volumes. Wind caused dropouts in my voice calls. The speakerphone was better—clearer, if a little fuzzy—although wind noise still caused some problems there. Wind noise also meant the phone had trouble understanding names for Bluetooth voice dialing, just like the F3 did.
While the Unify is an LTE phone, it lacks Sprint’s new Spark frequency bands. That means it will get lower LTE speeds than competitors like the LG Volt ($29.99 at Amazon) on Boost. In our Fastest Mobile Networks tests, we found that Spark more than doubled Internet speeds from an average of 3-6Mbps to 11-14Mbps. So not having Spark is a significant minus.
Sprint’s LTE network was too slow to do our LTE streaming video rundown test, so we had to resort to Wi-Fi. The 2,460mAh battery combines with the relatively small screen here to turn in solid, if not extraordinary battery life. We got 6 hours, 18 minutes of continuous YouTube streaming, surprisingly less than the 7 hours, 25 minutes we got with the Sprint version of this phone.
The Unify comes with 4GB of internal storage of which only 1.24GB is free. It runs the obsolete Android 4.1.2 with no expectation of an
, on a decent 1.2GHz Qualcomm Snapdragon 400 processor. That’s a version of Android from 2012, and it lacks some major performance enhancements that have come since then.
Although there’s a microSD card slot for your photos and videos, you can’t load apps onto it, which means you’ll be quite limited in the number of games you can store on this phone. Virgin seems to understand that, so most of the ‘preloaded’ bloatware on the home screen are just deletable shortcuts to Google Play.
Competition and Conclusions
We primarily recommend LTE phones nowadays. Sprint’s 3G network is so slow as to be almost unusable, and its LTE network is spreading. The future is LTE. Since the Unify is Virgin Mobile Custom’s only LTE phone, this is the phone we recommend if you’re looking for Custom’s flexible plans or parental controls.
Last year I was just impressed with the Optimus F3 having LTE at all. Now, there are better values at comparable prices. The LG Volt, an all-around better phone with a better screen, camera, and Sprint Spark, is $143 at Virgin as of this writing. On Boost, the superior HTC Desire 510 is $99.99. On Cricket, both the Moto G LTE and the Desire 510 are $149. If you aren’t married to Virgin Mobile Custom, those are all better choices for prepaid phones at this price point.

Hello,
the code for the temperature sensor DS18B20 works fine using only the display. But when I add the BLE code, I can't get it to work, it disconnects before receiving the temperature value. I have tested the same BLE code with another max30102 sensor and it works perfectly.
Can you help me?
Thank you
Show LessI have a MiniProg3, trying to get it to connect to PSoC Creator. When I first pulled it out of the box and plugged it in, I followed the steps in the MiniProg3 Program and Debug Guide . PSoC Creator said "Firmware is not fully loaded and device cannot be detected. Please Reconnect." I went through the troubleshooting steps on this forum post, including the Troubleshooting PSoC-3-4-5LP Programming Debugging Issues document, but nothing changed. The message was the same whether the MiniProg3 is connected to the target board or not.
Finally I replaced the included USB cable with another one I had on hand. It started working!
For a few days anyway. But now it doesn't work with any of my USB cables. I tried unplugging all the other USB devices and that didn't help. The behavior is the same on my work computer and my home computer.
Now when I try to program in PSoC Creator, it goes to the select target screen and hangs for a long time (see screenshot).
In PSoC Programmer, it says it connects and I get the blue dot by the MiniProg3 serial number, but there is a red FAIL in the bottom right hand corner of the screen.
Does that mean that my MiniProg3 needs replaced? Or are there some other troubleshooting ideas I can try?
Show LessHello, I've used the PSOC 4 and PSOC 5 and like using the PSOC Creator IDE for code development. I've now stumbled on the GUI generation with the PSOC microcontrollers. I want to learn more, can anyone tell me what software I need in order to create GUI's for the PSOC 4 and 5? Are there any videos on the steps to create GUI's? Kinda like the PSOC 101 videos on youtube.
Thank you

I want to make an application to get my notifications from an iphone through psoc 4 ble. I'm subscribing to ANCS service, i get the notifications, and after i want that data to send to windows to a java or c# application. What I don't know how to do or if it's possible: how do I make the connection between psoc and windows to send the data.
Show LessHello everybody,
I have the following problem: I have two glued boxes which have only 2 free GPIOs and where I have no acceess to the other GPIOs. The two boxes should be able to communicate via UART. For Tx( transmit) there is a ready-to-use block which I can put on each GPIO.
For Rx, there is no such a ready-to-use block an I have taken the source code from another forum post.(https://community.infineon.com/t5/PSoC-4/Software-Based-Uart-Receive/m-p/220861)
I can only receive characters if there is no delay in the source code. If I have a CyDelay() in my source code, then the Software Based Uart Receive no longer works.
Is there a solution to this? If you use an SCB UART block, you can only use certain GPIO pins. Can the GPIO pin somehow be forwarded to another GPIO pin? I am testing it on the Piosnieer Kit 042 with a PSoC 4200, but on the box itself is a PSoC 4100.
Best Regards
Michael
Show LessHi,
Working on a wireless capacitance sensor based on the CY8C4248LQI-BL583. All components are rated to 85 degC or more.
The sensor works fine in room temperature but raising the temp makes it fail as early as 51 degC.
Failure temperature depends on which software I run on the sensor board. With the simple "Find Me" example failure occurs at around 70 degC.
I have tried heating various components e.g. oscillators and capacitors. But most indications points towards that it is the MCU that fails.
I understand the the information provided is not enough to pinpoint the root cause of the problem. I'm rather asking for troubleshooting advice.

Hi,
We restart an old project developped with CY8C5568LTI-114 and we want to open the associated project. For the moment, we just want to analyse the firmware. After that, we redesign the product and we change the microcontroller.
The problem is we can't open the project because the old microcontroller is not recognize by the software PSoC Creator 4.4.
Could you help us to open this old project please ?
Best regards,
Thomas
