If someone was savvy enough to install a spyware app on your phone, they're probably also savvy enough to know how to hide it from you. Why do you think someone installed spyware on your phone?
It's always possible, depending on the spyware app. But remember that your Google activity will show lots of diffferent apps, many of which are obscure system apps. You'll worry yourself to death wondering if some techy-sounding app you've never seen before on your phone is spyware or not. The real question here is why you're concerned about spyware. Did you recently install any shady apps, or visit any shady sites? Does someone seem to know all of your activity? Keep in mind that it can be very easy these days for bad guys to know a lot about a person based on everything shared on social media. So if you're posting tons of pics from your current vacation, and a thief already knows your address from publicly available information, then they know that nobody's home, and will help themselves to your stuff.:'(
Here's my usual spiel on malware:
For the most part, it's still quite difficult to get an actual virus on your phone, because malware requires you to manually accept the installation (which is why they try to fool you into thinking you're installing something legitimate). Use common sense:
1. Avoid shady websites that deal with things like porn, gambling, and "free" (aka pirated) apps/music/movies.
2. Never ever tap on a link that appears in a popup while browsing, especially if they're warning you that your phone is infected -- they're just trying to scare you into installing some bogus "antivirus" app that is probably malicious itself.
3. Only install apps from well-established app sources like Google Play Store or Amazon Appstore. Read a bunch of app reviews before installing an app to look for any complaints about adware or suspected malware.
4. Turn on Google Play Protect features in Settings>Google>Security. This allows Google to periodically scan your phone's apps to look for malware.
5. Turn off "Unknown Sources" in Settings>Security. This prevents any app that wasn't obtained from Google Play Store from being installed (which could include malicious apps that are inadvertently downloaded).
When I clicked on that link it opened nothing but after 1 day when I downloading a pic from Twitter on Chrome browser it says permission or access denied and after 2-3 days then after 2-3 days there is the problem of screen overlay detected suddenly.What kind of weird behavior? If you can't find any unusual or unrecognized apps in your app list, it might be a good idea to a backup your important data, then do a factory reset. When you set the phone up again, don't restore from a previous system backup. Set the phone up as a new device, and then restore your backed up data afterwards. Don't let any app automatically reinstall -- install them manually yourself.
When you tried to download that pic, was it the first time you had tried in a while? Go to Settings>Apps and select Chrome, then Permissions. Is Storage permission turned on?
Screen Overlay can happen with other legitimate apps: https://www.howtogeek.com/271519/how-to-fix-the-screen-overlay-detected-error-on-android/

It depends what you call a "spy app". Google tracks everything we do on our phones. Are they considered a "spy app"?
No not the first time that's y I get tensed.
Is that indication of hacked phone?
Clicked on a link from a chat room on your phone = bad idea. Great advice above. You should probably add a paid version of Norton, etc.Yeah actually I clicked on a link on stranger chatting site send by anonymous asking for her pic but there opened nothing . But after that incident I found some weird behaviour of my phone
So is Storage permission turned on for Chrome or not?
If you're really worried, then backup your important data and do a factory reset. Make sure you set the phone up as a new phone, and don't allow any app to automatically reinstall -- manually install your apps by yourself, and do it one by one, rather than all at once.

Asking for a 3rd time -- is storage permission turned on for Chrome? Trying to determine if this might be the reason you're having trouble downloading pics from Twitter on Chrome.
I realize that you didn't manually turn off Storage permission, but odd things can happen -- maybe the permission turned off by itself for some reason. Just to be sure, go to Settings>Apps, select Chrome, then tap Permissions, and see if Storage is on or off.
