I had used this phone for almost 2 years and 8 months. The phone has 3 GB RAM which is still the best as compared to today’s mid range phones and Apps available on Android. Needless to say performance was good. Internal storage is 16 GB and this can be a problem if unwanted files are not moved or cleared as downloads happen by default in the internal memory.
Picture quality is good and can serve the purpose. Video capture is decent and also has slo mo recording.
Battery backup is good and last for 15 - 18 hours depending on usage. My phone was in usage for almost 4 hours talk time daily basis and on 4 G always.
