Performance
Running on Android 4.0 Ice Cream Sandwich, the Karbonn A25 is powered by a dual-core 1.0 GHz processor. Though performance is on the lower end by modern benchmarks, the setup was intended for basic smartphone tasks such as browsing the web, making calls, and texting. It should support some lightweight applications, but users are likely to encounter limitations with more demanding apps. The internal storage is a meager 114MB, which necessitates reliance on a microSDHC card for additional storage.
