The owner reports that after the One UI 7 update in late July 2025, the touchscreen intermittently stops working when unlocking and the phone restarts unexpectedly, including at night while charging.
What to check. A One UI 7 update can introduce touchscreen and random-restart bugs on the A05; check for a newer software version before assuming hardware failure.

A buyer review states the LCD is bad and the screen cannot be touched, and that all users complain about the same thing, asking Samsung to pull the phone from the market.
What to check. If you buy an A05, test the touchscreen thoroughly within the return window; this is the most repeated failure across sources.

It lists as classic signs of a worn battery: faster discharge than before, sudden shutdowns at 10-30%, heating while charging, and a jumping percentage indicator.
What to check. If the A05 starts shutting down at 10-30% or heating on charge, the battery is the likely cause; a replacement is the standard fix.

A buyer of a Galaxy A05 in Turkey reports the battery drains very fast since purchase and the case has a slight bend, with no impact or user error, and that Samsung asked for about 3,500 TL for service despite the warranty.
What to check. In Turkey, fast battery drain is reported on the A05; if under warranty, push for free service rather than paying the quoted fee.

An owner reports a green line down the screen appearing randomly after a little over a month, with no damage; a Samsung helper replies a green line usually suggests a physical fault needing a screen or cable replacement.
What to check. A green line on a month-old unit is a hardware fault, not software; expect a screen replacement rather than a fix.

The owner reports the phone overheats and suddenly drains the battery when running multiple tabs, and crashes.
What to check. Heavy multitasking on the A05 can trigger overheating and sudden battery drain; expect this in demanding use.

The owner reports the screen began freezing often after about five months, requiring a power-button reset each time, and that the problem persisted after clearing storage and resetting internet settings.
What to check. Frequent screen freezing that needs a hard reset may not be fixed by clearing storage; it can require service-center attention.
