GoSolo Verdict
The BLU Advance 4.0 is a 2019 budget phone built for basic calls, texts, and light browsing in markets where cheap connectivity matters more than speed. It is exactly what it promises: a no-frills device that works, but the 512MB RAM, 2-core processor, and HSPA-only network feel dated even for its price point, and there are better budget options available today.
Strengths · 4
- Removable battery: rare in this era, useful for field work or where charging is limited
- Extremely light at 104g and compact at 4.0 inches, genuinely pocketable
- Dual SIM with dual standby for users managing multiple networks or regions
- Runs Android Go (Oreo), which is stripped down to run on minimal RAM
Trade-offs · 3
- 512MB RAM makes even basic multitasking sluggish; this is sub-entry-level even for 2019
- HSPA-only, no 4G LTE means slower data speeds than 3G devices of the same era could manage
- 1300 mAh battery is tiny; claim of 18 hours talk time on 2G is deceptive when most networks worldwide are moving away from 2G
