Zoom any­thing on a web­site

The pinch-to-zoom mag­ni­fy­ing ges­ture is widely used, but it doesn’t work all the time. You can’t, for ex­am­ple, pinch to zoom phone and tablet home screens, while many ‘mo­bile’ web­sites dis­able this fea­ture. But there are hid­den tricks that’ll let you zoom any­thing, any­where.

In IOS, open Set­tings, then tap General, fol­lowed by Ac­ces­si­bil­ity. Tap Zoom, then tap the switch to On. From now on, us­ing three fin­gers to dou­ble-tap the screen will zoom into any­thing, in­clud­ing your de­vice’s home page and any web­site. To move around the mag­ni­fied im­age, tap, hold and drag with three fin­gers. To change the zoom level, dou­ble-tap then drag up or down.

In An­droid, open Set­tings, tap Ac­ces­si­bil­ity, fol­lowed by ‘Mag­ni­fi­ca­tion ges­tures’, then switch the set­ting on. You’ll now be able to zoom with a sin­gle­fig­ure triple-tap. Ad­just the zoom level with a stan­dard two-fin­ger pinch ges­ture, or pan the view by drag­ging two fin­gers.

On Kin­dle Fire tablets, swipe down from the top, tap Set­tings, Ac­ces­si­bil­ity, then switch Screen Mag­ni­fier to On (see screen­shot be­low left). The ges­tures are the same as on an An­droid de­vice.

Dis­able ‘adap­tive bright­ness’

Do you some­times feel your screen is brighter or dim­mer than you’d like? This is down to the adap­tive-bright­ness fea­ture, which uses the de­vice’s am­bi­ent­light sen­sor to au­to­mat­i­cally set the ‘ideal’ bright­ness level. Great in the­ory, but all too of­ten very un­re­li­able.

To dis­able it on an ipad or iphone, open Set­tings, tap ‘Dis­play & Bright­ness’ then switch Auto-bright­ness off. In An­droid Set­tings, tap Dis­play then switch off ‘Adap­tive bright­ness’.

Set the screen for your par­tic­u­lar colour blind­ness

Mil­lions of peo­ple see screen colours dif­fer­ently be­cause they have a colourvi­sion deficiency – com­monly known as colour blind­ness. Colour fil­ters can help you dis­tin­guish colours if you suf­fer from this con­di­tion.

In IOS, tap Set­tings, Ac­ces­si­bil­ity, then Dis­play Ac­com­mo­da­tions. Next, tap Colour Fil­ters, tap the switch to On, then be­low that tap the type of colour blind­ness that’s rel­e­vant to you. For ex­am­ple, choose Protanopia if you strug­gle to dis­tin­guish blue or red from green (see screen­shot be­low).

In An­droid, tap Set­tings, Ac­ces­si­bil­ity, then scroll to the bot­tom and tap ‘Colour cor­rec­tion’. Switch it to On, then tap ‘Cor­rec­tion mode’, fol­lowed by the rel­e­vant fil­ter.

Make screen fonts big­ger

If you’re strug­gling to read what’s on your screen, you can in­crease the size of the font used in IOS and An­droid. In IOS, tap Set­tings, Ac­ces­si­bil­ity, then Larger Text. Drag the slider to in­crease the font size. If you need to go larger still, ex­tend the slider by switch­ing Larger Ac­ces­si­bil­ity Sizes to On. On An­droid de­vices, tap Set­tings, Dis­play, ‘Font size’, then tap to choose a larger size. If you have a Kin­dle Fire, swipe down from the top of the screen, tap Set­tings fol­lowed by ‘Dis­play & Sounds’, then tap the plus (‘+’) but­ton next to Font Size.

Ap­ple’s IOS has fil­ters that help peo­ple with colour blind­ness
