Samsung Galaxy A35 5G troubleshooting

Published specification

What is true of this model and changes how you fix it

• What owners run into
  Mid-range phones feel slower as storage fills, and the A35 has no memory card slot, so owners meet storage-full warnings. Others see apps close in the background and a camera that is slow to focus in low light.
• How to approach a fault
  Free storage first, since a nearly full phone slows everything, and then restrict background use for apps that restart. Updates arrive for several years, so keep the phone current.
• Finding your model and software
  Settings, About phone shows the model number SM-A356 and the One UI version. Samsung promises four Android updates and five years of patches, which is long for a mid-range phone.
• Keeping storage under control
  The A35 has no memory card slot, so storage is fixed. Delete downloaded videos, clear caches in Device care and let Google Photos back up and free space. A phone with less than a tenth of its storage free becomes slow and unreliable.
• Charging and battery
  The A35 charges at up to 25 watts and does not include a charger, so buy a compatible USB Power Delivery adapter. Its 5,000 milliamp-hour battery lasts about two days of light use, and turning down the refresh rate extends it further.
• Getting more from the A35
  The 120 hertz display and the big battery reward a few habits: set the display to adaptive refresh, remove widgets you do not use, and let apps sleep when you are not using them. Install apps from the Play Store or Galaxy Store only, and keep one or two gigabytes free for the system to breathe. These simple steps keep a mid-range phone feeling fast for years.
• Four updates, five years of patches
  Samsung's long promise for the A35 means the phone gets new Android versions for four generations and patches for five years, which makes the first sign of a fault worth fixing and not replacing. Check Software update monthly, read the update notes for battery and camera changes, and keep a note of the date of the last patch so you can see whether Samsung has shipped a fix for the thing you are seeing. Back up with Samsung Cloud or Google before any big update so a bad install can be rolled back by restoring.
