Recently, I bought a Lumia 520 as a low end device to replace my dad’s existing Windows Phone 7…as he complains App selection on his phone wasn’t great. It explains because Windows Phone 8 is growing and people are developing for that platform.
Enter Focus Flash 4g- http://www.phonearena.com/phones/Samsung-Focus-Flash_id6138
- 1.4 GHZ processor, Snapdragon S2. 512 MB Ram, Windows Phone 7.
Enter Lumia 520- http://www.phonearena.com/phones/Nokia-Lumia-520_id7745
- 1.0 GHZ dual core processor, Snapdragon S4. 512 MB Ram, Windows Phone 8.
Windows Phone 7 performs better on a two year old device running on single core processor with 512 MB. Windows Phone 8 (update 3) in comparison, suffers dramatically performance wise with better processor and same amount of RAM. Lumia 520 is not that great a device as it is hyped up to be. In under 24-hours of using the device, Launching Whatsapp constantly freezed his device after. Similar tax never brought his OS to crawl on Focus Flash, running Windows Phone 7.
One thing Microsoft failed to address in Windows Phone 8 is efficient memory-use. It fails to even match its own effort in mobile. Windows Phone 7 is the supreme undisputed leader in low-end handset market. Other than app-selection, I don’t know why manufacturers use Windows Phone 8 over 7. Here is a picture from Build 2013 that backs my claim for Why Windows Phone 7.1 was and still is more efficient than Windows Phone 8 on low-end.
