I finally got a replacement A53 from Straight Talk, still on Android 12. I missed this phone, lag isn't so bad if you uninstall the bloatware and set RAM+ to 0 in ADB. Is there really a big difference on 13?
I have had the unlocked version since it was released last spring. I preordered it to replace a OnePlus 7 pro that had a failing battery. I really miss the wow factor of the 7 pro and the pop up selfie camera. Also the 7pro was smoother running by a bit.
However the battery in the A53 is great. Samsung has been doing much better than past samsung phones I had ad updates. my 7pro still had android 11, the A53 came with 12 and now today got 13. I do like the 5G data speeds and having an SD card slot again.
I just bought the a53 last night (old phone is a oneplus 6t) and frankly, I'm under-whelmed. Reason being is that my old phone had no lag -- everything was butter. A53 has a 1/2 second lag and sometimes requires a harder press on the touch screen, so it seems.
the A53 has a better chipset, slightly bigger battery and no headphone jack. It's more of a "side grade" than a true upgrade.
I hope the aforementioned helps. =)
