a.k.a my test machines.
I’m a poor student with no source of income (except what my parents gave me and whatever amount of money I managed to save every weekend) , so the devices and OSes on where I test the apps are not the newest, fastest, most cutting-edge devices and OSes available out there. This is also the reason I will only review free apps. But if those apps I had tested work on my devices, it possibly would work on yours too.
My devices are:
Samsung 370R4V laptop
Processor: Intel Pentium 997 (1.6 GHz) dual core, Resolution: 1368 x 768 (14″), Storage: 500 GB, RAM: 3.8 GB, OS: Windows 7 32-bit/Xubuntu 16.04 LTS 32-bit (dual-boot)
I bought this laptop on May 2013. It came with no OS installed, but I got the storage divided into 3 partitions and Windows 7 32-bit installed right on the place where I bought it. Windows 8 was already released at that time, but I never get comfortable using it.
I used to use Ubuntu (from version 12.10 to 14.04 LTS) but switched to Xubuntu (starting from 16.04 LTS) on 2015.
(Yes, I prefer LTS releases)
I also stopped using Windows in 2016, since everything I want to do with this laptop (school/internet/entertainment) can be done using Linux.
Motorola Moto M
Bought on 2017 as a birthday present. It’s a phone with near-stock Android, 2.14 Ghz CPU, 4 GB of RAM, fingerprint sensor, USB type C port, and 3050 mAh of battery capacity. So far, it’s a reliable (and pretty) medium-range phone.
Asus Zenfone 4C
On July 2015 I was given this phone as a triple birthday/graduation/college enrollment present. It’s a not very expensive phone with pretty, solid design, good speakers, and Android 4.4 Kit Kat installed. It has lots of pre-installed Asus apps that can’t be disabled, and being an entry-level phone, it has some performance and battery problems.
Conclusion: Don’t buy an entry-level smartphone (and stick to stock Android).
Samsung Galaxy Mini GT-S5570
Dimensions: 110.4 x 60.8 x 12.1 m, Weight: 105 g , Screen: 240 x 320 pixels, 3.14 inches, Internal storage: 100 MB, External storage: 1.84 GB, CPU: 600 MHz, OS: Android 2.2.1 Froyo. Specifications taken from here.
I bought this phone on January 2012.
The internal storage of this phone is ridiculously small, and I would be warned with a ‘Low Internal Storage’ notification every few months. I know you’re laughing at me for still using Froyo, but my phone is still really reliable for my daily needs (aside of not being able to test pretty apps only available for 4.0 and up). Sometimes it would froze when handling many tasks, but that’s not really a problem.
Genymotion 2.3.0, Free Version
Since October 2014, I’ve installed the free version of Genymotion on Ubuntu (it’s the only Android emulator available on Linux, to my knowledge). It’s based on VirtualBox, which I’m already familiar with.
Although it can’t replace an actual Android device, and its performance is not as great as the real thing (just like any virtual machines) I can use it to test out apps not available for both my phone and phablet, because of version and/or storage limitations.
I’m currently using a Sony Xperia S virtual device (it’s the type of phone I’d like to buy) running Android 4.4.1, with the default 1024 MB base memory and 720×1280 px screen resolution.
