User Reviews
I was tired of poor data speed and service with a competitor carrier and I took a gamble with the A20 and Metro. Coming from an iPhone Xs (yes a downgrade), I am mostly pleased with the A20 with the 3GB of RAM and 32GB of ROM. I opted to put a genuine Samsung Micro SD Card 64GB in and also purchased a case and screen protector. The screen is nice and robust. I see pixels on the 720p screen with readers on, but it saves battery.
The audio on calls is excellent, even outdoors. It is loud and crystal clear and I keep the earpiece volume at about 80% or so. The UI is snappy for a mid range phone. Response is fast and touch sensitivity is great. I wish I can keep contact notification settings even if I delete an contact from my SMS List. The fingerprint ID works well.
So far the A20 is working out well as of 3/4/20 where I also received the software update ending in ATB3. I have got the phone almost where I want it setting wise. I am experiencing speeds of over 150/50 Cat 4. Maybe this has a Cat 6 LTE or higher? Take your time registering your fingerprint.
- Android 9.0 Out of the Box
- Dolby ATMOS
- Good AMOLED 720p Screen is vibrant.
- Good Standby.
- Raoid Battery charging.
- Experiencing LTE Speeds over the Cat 4 of 150/50.
- Great Call Audio (Earpiece).
- 3/4/20 Software Update ending in ATB3.
- SMS Notifications must be reset if contact is deleted from SMS List.
- Speakerphone is a bit low in volume.
