16 October 2026Phone battery replacement: forget everything you knowSome of what people know about phone batteries comes from older battery types. Today’s lithium-ion batteries do not need to be run flat; many phones manage overnight charging themselves; and a high mAh figure on a label is not always the real capacity. Heat is one of the things that wears a battery most.

Do not use bleach and do not let moisture into any opening.

16 October 2026Samsung Galaxy S7 Edge screen replacement: what to watch on a curved screenThe Galaxy S7 Edge’s screen curves at both edges, so it cracks easily at the edges in a drop and a replacement needs a part that fits the curved edges.

16 October 2026What is a ghost screen? Ghost touch or ghost image?“Ghost screen” is used for two different problems. With ghost touch, the screen taps, opens apps or types without you touching it.

16 October 2026iPhone 12 cracked front glass: glass only or the screen?When the front glass of an iPhone 12 cracks, replacing only the glass may be possible if the OLED panel underneath has a flawless picture and touch; with stains, lines or touch faults, the screen is replaced. The iPhone 12 and 12 Pro share a screen size; the 12 mini and 12 Pro Max differ.

16 October 2026Ink spreading on a Samsung screen: what to do while the stain growsOn a Samsung AMOLED screen, an ink-like stain starts as a black, purple or green blot when the inside of the panel is damaged, and it can spread over time.
